Chevrolet Blazer 2022 — Problemas reportados

The contact owns a 2022 Chevrolet Blazer. The contact stated that while operating the vehicle, the check engine warning light remained illuminated, and after turning off the vehicle, the fan continued running, causing the battery to drain. The vehicle was taken to the local dealer to be diagnosed, and it was determined that the thermostat needed to be replaced. The vehicle was not repaired. Additionally, the contact stated that recently while operating the vehicle, the steering assist warning light remained illuminated. The cause of the failure was not yet determined. The manufacturer was notified of the failure and informed the contact that the vehicle was not covered under an extended warranty coverage associated with the thermostat. The failure mileage was 51,000.

1. Vehicle completely shut off at a stoplight during the nighttime. The vehicle lost all power including lights, hazard lights, horn and electrical system. Would not start back up for several minutes while sitting in the middle of the highway during the nighttime, creating an immediate safety hazard in traffic. Vehicle self-corrected after a few minutes.

I had no warning or indication whatsoever that my battery was going bad. I was at a major red light and my car shut down, then started back on its on with the entire panel lite up. The light changed and when I tried to turn I had hardly any stirring and almost no brakes. I almost ran into the car in front of me. I was able to get it into a parking spot and then it still gave me no light or notice of a battery issue. Because it had a recall on it that was repaired four days prior I had it towed to the dealership. They told me it was the battery but even when I picked up the car (for AAA to install the battery), it still showed 13.6% power on a 14 volt battery. This issue almost caused me to have an accident and caused me to waste $168 for a tow.

The contact owns a 2022 Chevrolet Blazer. The contact stated that upon coming to a complete stop, the vehicle shut off. After several attempts, the vehicle was restarted, and the contact continued to drive. The vehicle was taken to an independent mechanic, where it was diagnosed, and the contact was advised that the failure was not duplicated. The vehicle was taken to a dealer where it was diagnosed, and the contact was informed that the failure was not duplicated; however, the dealer suggested that the fuel pump driver control module be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 83,000.

I am reporting a severe powertrain safety hazard involving my 2022 Chevrolet Blazer at approximately 69,000 miles. The vehicle's 9-speed transmission is experiencing a critical internal hydraulic failure that causes unpredictable and violent lurching. Specifically, there is a severe delayed engagement when shifting into Reverse. The engine revs without moving until the hydraulic pressure suddenly spikes, causing the vehicle to violently slam backwards and catch the gear. Furthermore, the transmission exhibits harsh and slipping shifts while driving forward, specifically violently jerking during the 2nd-to-3rd gear upshift. ​These exact symptoms align with widely documented hydraulic control and valve body defects in the GM 9T50/9T65 transmissions, which are known to cause harsh shifts, delayed engagement, and flaring between gears. Concurrent with these transmission failures, the ABS warning light illuminated. An independent shop misdiagnosed the severe drivability issue as a standard ABS fault, while a local Chevrolet dealership denied Goodwill assistance despite this being a premature internal transmission failure. ​This creates a severe safety hazard. The unpredictable lurching in Reverse endangers pedestrians and other vehicles in parking lots. Additionally, the violent shifting at speed creates a high risk of sudden internal component failure and a complete loss of propulsion while driving in active traffic.

The contact owns a 2022 Chevrolet Blazer. The contact stated that after the dealer had performed a software update under TSB Number: N212355740, the computer blew up. The contact was informed of the failure, provided a loaner vehicle, and advised that the manufacturer was notified of the failure by phone. The dealer was awaiting a callback from the manufacturer before performing further repairs. The contact expressed concerns and dissatisfaction that the dealer had recently confirmed the vehicle was covered under the TSB, but the manufacturer had failed to send a notification of the TSB. The failure mileage was approximately 12,000.

"Steering Assist is Reduced, Drive With Care" showed up on the dashboard. The temperature gauge dropped to dead cold. Once the car was parked and cut off, the fan still kept running for 5 minutes. From my research it seems these are the signs of a thermostat being stuck open. It also seems this is a very common problem with this car, according to the internet. This vehicle has around 70K miles. There were no other issues prior to this failure.

While driving on the road at/or about 45 mph to my workplace, the transmission gave out and lost forward momentum. I had the transmission serviced for its second serivce at 84705 miles just ten days before this happened. The first service occurred around 47k miles when I learned about this issue with Chevrolet transmissions.

As I accelerated after the traffic light turned green the vehicle stalled. I was able to move the vehicle to the curb on XXX [XXX] is a two-way road. The vehicle stalled while on an active road which could have led to my vehicle being rear ended causing potential injuries to myself and other drivers. The engine turned over and there was fuel in the gas tank, however, the vehicle wouldn't start. A warning light showed: "low battery", but since the engine was trying to start, it seems unlikely that the battery was low. A second warning light showed: "battery saving" mode. These lights appeared once the vehicle was parked on the curb of the road. The vehicle was towed to David Chevrolet, a GM dealership on [XXX] about 2 miles away.

My 2022 Chevrolet Blazer abruptly Shut down all power for about five seconds while I was stopped at a red light. The vehicle restarted after I pressed the push-button ignition, but the dashboard displayed a brake system error warning with no explanation of the cause or instructions for next steps. No other warning lights preceded the shutdown. The vehicle appeared to resume normal operation after restart, but the brake system warning remained. This appears consistent with complaints filed by other 2022 Blazer owners describing simultaneous electrical and brake system failures.

Intermittent electrical defects are beginning to occur that impact the power steering or power brakes. After starting the vehicle, there are times either the power steering or the power brakes do not function. When the braking defect occurs, the engine warning lamp is displayed and indicates brake system control module. Sudden switch to manual steering or manual braking are a safety hazard. A couple ignition recycles eventually corrects the electrical defect and restores the vehicle to normal operations. Vehicle has been dropped off at dealership for warranty repair.

My infotainment system has completely blacked out. I have no navigation, no rear view camera or warning signals. I have no phone and no SOS emergency calls. I have no music no lane merging alerts. My charging station does not work in the front of the vehicle.

I have been smelling engine coolant for some time and found a leak on the drivers side top seam where the aluminum meets the plastic tank on the radiator. This is a known problem with 2019=2026 Chevy Blazers by GM and it still hasn't been resolved. After researching, I have found numerous Blazer owners that have this same issue and some are on 3rd and 4th radiator replacement. I am afraid to drive the vehicle due to the leak that could leave me and my family stranded on the side of the road. I am also concerned about a major leak or seam separation that could allow a large amount of coolant out that could get on the tires and cause loss of vehicle control as a result. Also, the leaking coolant is a hazard to any animals that are around as the coolant puddles under my vehicle after driving. At this point, the Blazer is running hotter and I had to add coolant. I just called to price a new radiator...$450 and install...$1,025...that isn't a cost I should have to take on with GM knowing about this issue for years.

The contact owns a 2022 Chevrolet Blazer. The contact stated that the coolant was leaking from the radiator. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the radiator needed to be replaced. The contact was informed that the dealer was replacing a lot of radiators for similar failures. The vehicle was not repaired. The manufacturer was contacted, and a case was opened. The failure mileage was approximately 49,500.

Car stalled and told me to put in neutral. Could smell gas. Car wouldn't come back on. Code u18a2 (lost communication with fuel pump communication module), part is available for inspection, we were all at risk due to the car stalling on the highway with no prior warnings, check engine light came on after car stalled, ordered new part from GMC, fix the issue right away. This part has been recalled on other models just not on 2022.

BROUGHT MY CAR TO CHEVROLET CENTER IN WINTER HAVEN FLORIDA BECAUSE I HAD 2 DIAGNOSTIC CODES SHOW UP WITH A CHECK ENGINE LIGHT, THE CODES WERE (U1345: Indicates a communication fault on the LIN (Local Interconnect Network) Bus, usually tied to modules like the active grille shutters, cooling fans, or charge air cooler (CAC) pump.U0632: Indicates lost communication specifically with Cooling Fan 1.) THE DEALERSHIP TOLD ME THEY DIDN'T FIND ANY CODES IN THE SYSTEM AND THEY TRIED TO CHARGE ME $165 FOR A DIAGNOSTIC FEE. RIGHT AFTER I LEFT THE DEALERSHIP I WAS HAVING THE SAME CODES POP UP, WITH THE CHECK ENGINE LIGHT AND MY CAR WAS OVERHEATING. CHEVROLETS ECM/PCM WARRANTY IS 8 YEARS OR 80,000 MILES.

Thermostat fails resulting in steering power reduced, temperature goes to C and fan runs overtime. This thermostat or temp sensor fails intermittently and fixes itself. Car could be overheating and you wouldn't know. This part is recalled on 2021 Blazers already.

I have a 2022 Blazer with a 3.6 engine. The thermostat has failed and dealer says only certain blazer vehicles are covered under aspecial warrnty exstesion. I know several people having the same problem.I have a check engine light, with a scan shows code P0128(thermostat0. I also have a display of power steering assist reduced and tempature gauge stays much lower than normal.. When you turn vehicle off the high speed cooling fans remain running ub=ntil battery is dead.

I have received this warning a few different times “Steering Assist is Reduced". Which causes my vehicle to not blow cold air when AC is on. Fans are louder than normal. And when I turn off my vehicle fans continue to run for roughly around 8 minutes.

My engine coolant temperature sensor failed. Replaced it and still not fixing the issue. This takes my steering assist away as they are all interlinked? I have seen on forms this is a common issue. This has the potential to blow up my engine, I’m not sure how this is not a recall with so many 2020-2026 blazer owners having the same issue.

My Drive Assist stopped working. Then my Air conditioning stopped blowing cold. Then the temperature gauge stopped working. Upon turning the car off the fan continued to run for several minutes. Took to repair shop where it required a new thermostat housing, coolant temp sensor and coolant flush. The total cost for repair was $1,131.52. The car has 37,000 miles on it. Barely out of warranty. This is a well-known issue among Chevy owners.

When shutting off the car, the fan continued to run. I started the car up again to see if this would allow the fan to turn off. No luck. The steering assist was dis-enabled on the dash. I took my car to the dealer to find out that it has a bad thermostat and that my radiator was leaking. The thermostat was covered but I had to use my extended warranty to pay the additional repair. My deductible for my extended warranty is $300.00. My daughter has a 2021 Chevy Blazer and the same situation happened. There was a recall and all her parts were covered.

Transmission completely failed while driving at highway speeds.

Driving the vehicle when all of a sudden the engine shut off. All electrical systems continued to function. Luckily this occurred at low speed in a parking lot but had it happened at high speed on the freeway it could have been a huge safety risk. The vehicle was towed to a nearby automotive shop that diagnosed it as a bad fuel pump controller. There is an open GM recall that includes the 2021 Chevy Blazer (and a suite of other GM vehicles), but not the 2022 Chevy Blazer. I am concerned that the GM recall does not fully cover all of the vehicles that could be impacted by this issue. Date: September 11, 2025 Subject: N252516900 - Emission Recall Fuel Pump Power Control Module [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Unknown…. Cut open my shin (leg) on the bottom corner of my driver’s door (black plastic side molding). That part is sharp! Required ER with 14 stitches on 9-24-25. As of today I’m still recovering.

Car is displaying a “Steering assist is reduced drive with caution” engine light is on and fan continues to run for 5-8 minutes after car is turned off. Was told by a mechanic it is a P0128 code, coolant thermostat. This is the third time it has happened in the last year. Other two times the codes cleared.

Incident Description: While my wife was driving our 2022 Chevy Blazer at approximately 40 miles per hour, the vehicle’s dashboard suddenly went dark and became unresponsive. Multiple warning lights illuminated simultaneously, including the check engine light, ABS light, and other system alerts. The dashboard appeared to flicker as though it was repeatedly shutting down and restarting. When the brake pedal was applied, it offered no resistance and traveled completely to the floor without slowing the vehicle. To bring the vehicle to a stop, my wife shifted into neutral and allowed it to coast until it came to a complete stop. Fortunately, there were no intersections or other vehicles in front of her at the time, preventing a potential accident. This incident raises serious safety concerns, as both electrical and braking systems appeared to fail simultaneously.

Put my car into park and the fan kept running continuously. I noticed that the engine temperature gauge did not move off of cool either. When I drove it, I got an alert that the ‘steering assist was reduced’ and shortly after my check engine light came on. My safety was at risk due to the fact that I couldn’t monitor my engines temperature and it very well could have been overheating and I would’ve never known. I took it to the dealer and they did confirm that my thermostat was stuck open and wasnt allowing my engine to get up to temperature. My ecm module had to be replaced as well. The mechanic said, had it closed my engine would’ve overheated with no signs until it was too late.

Control arm snapped on the I-71. Going 70 miles an hour when it happened. Definitely could have been a major accident but luckily no cars were around us when it happened. i rode over a bridge's transition and heard a big pop like a tire. Then it sounded and felt like we were riding on a rim. When we got out we saw what had happened. No warnings or anything before this happened.

Automatic transmission and radiator. Vehicle shifted hard and then would not go to a higher gear after pulling out into an intersection. Vehicle was pulled over to side of road and shut off. Restarted and tried to merge back onto main road and while trying to accelerate, the rpm’s went over 3500 quickly and wouldn’t shift once the vehicle hit 30mph. The engine light came on. There has been no previous engine lights or issues. Scheduled an appointment at a Chevrolet dealership and had the vehicle towed on a flatbed trailer to be looked at. I stated that there was a major problem/issue with the transmission and explained the problem. In their notes it states they took it for a test drive before even checking the transmission fluid for metal particles. I told them it was a severe failure and was barely drivable. It was able to drive up in the trailer to be towed, but never shifted out of 1st gear. We are a little over 64,000 miles and the warranty cut off is 60,000. The dealership states that the transmission needs replaced and the cooling system as well since metal particles made it into that system as well.

While driving, the vehicle displayed a “Service Power Steering” warning message, and shortly after, the steering became noticeably heavier and less responsive. The issue occurs intermittently but has worsened over time, creating a serious safety concern because loss of steering assist could occur at any speed. The dealer diagnosed the problem as a failure of the electronic power steering module and rack-and-pinion assembly, quoting an estimated repair cost of approximately $2,500. The vehicle has only around 56,000 miles and has been maintained as recommended. The dealer confirmed the issue but stated that General Motors would not cover the repair under warranty or goodwill assistance. This defect poses a significant safety risk, as a sudden loss of power steering assist can make the vehicle difficult to control, especially during turns or emergency maneuvers. There were no accidents or injuries, but the potential for loss of control is high. The warning message and loss of assist can be reproduced and have been verified by the dealership. The vehicle has not been repaired yet, and the defective parts are available for inspection upon request.

Increasing speed by itself, let foot off gas pedal and gas pedal sticking, 1st time I tapped brakes and it quit. 2nd time it did not. I had to slam brakes and hokd until the point they had overheated and smell burnt and filed a separate complaint for that today. Gas pedal sticking and self accelerating. Pedal to the floor accelerating. I do not drive like that and scared the hell out of me. I bout it 5 days ago from a Chevrolet dealership. I'm tired of rip offs. Next one best be brand new and they reimburse me for outside mechanical I inspection period. Bc I trust no dealer now. Went from 7p to about 95 in 10 seconds for 10 min. Not sure what braking did bx I coukd care less about the phone whike I am trying not to hit cars in front of me literally almost jammed an 18 wheeler and moving truck with me pushing the brakes as gmhard as I could.

Accelerating without pressing gas pedal and gas pedal won't release with braking. Brakes overheated and this went on 10 minutes before I got it to release the gas pedal so I could safely stop. I almost hit 4 vehicles on the interstate because the gas pedal went to the floor all the sudden.

Temp sensor quit working. I have seen online there are tons of people having this exact problem but no recalls issued

1. Fuse array has failed, and yes it is available for inspection upon request 2. The car overheats, posing a threat to passengers lives due to having to pull over on the side of the road and being struck by other drivers. 3. Yes it has been confirmed by a dealer/service center. 4. Yes it has been inspected by certified service technicians. 5. Yes, the engine light comes on and the dash says “Engine power reduced” and then “vehicle overheating, please pull off the side of the road and turn engine off”. There were no symptoms leading up to the vehicle overheating. This first occurred in April 2025, and occurred again September 6, 2025. When speaking to the dealership, they stated that this is a widespread issue with Chevrolet Blazers and because of how big this issue is, new parts are on back order until middle to end of October. I cannot drive the vehicle to go grocery shopping or bring my daughter to daycare. Because this is a widespread problem, there needs to be a recall issued. Chevrolet installed faulty fuse arrays in their vehicles and this is their fault for this happening at such a large scale.

The contact owns a 2022 Chevrolet Blazer. The contact stated that upon stopping at a red traffic light, the vehicle's auto start/stop system activated and turned the engine off. The warning message "Brake System Failure - ESC- Steering Assistance Reduced". The driver was able to pull to the shoulder of the roadway and turn the vehicle off. Upon restarting the vehicle, the vehicle returned to normal functionality, but the failure recurred. The check engine warning light was illuminated. The vehicle was not diagnosed or repaired by the dealer or an independent mechanic. The manufacturer was notified of the failure, and a case was filed. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was 121,000.

2023: 16K miles, the Chevrolet Blazer in questions transmission went out; thus requiring it to be brought into the dealership for repair; It was "repaired" and given back to us. A few days after said repair, I was driving it with my son in the vehicle, and the transmission went out while on the highway. I was almost hit from behind as I limped it to the side of the road. A brand new transmission was put in. During this time, there was also issues with the brakes where they were making noises. 2025: Blazer check engine light came on. On the way to get it diagnosed, it began to overheat; we were limping it to the side of the road when it stated "engine overheating, vehicle turning off". The safety system for shutting down when overheating worked, however, I was in the roaad again. Thus putting me in danger of being hit. We just received notice from the dealership that it is (as of this moment) a cooling fan, AC pressure switch, thermostat, and a cracked radiator. We are waiting on the technicians to finish checking it to see if there are any other issues.

Intermittent dash warning: "Action Required. Steering Assist is Reduced. Drive with Care." Power steering is sluggish when this happens. Having this happen while driving could be dangerous. Only stays on for a few minutes then goes away. This started with only 10k miles and has been continuing for 2+ years. Based on what I've read online, this is a known issue with the thermostat and/or coolant temp sensor. Dealership refuses to fix it unless it's throwing a code while in the dealership. Of course, it never throws the code while at the dealership.

Vehicle gear shifter is stiff and difficult to pass from Park to Drive--the gear shifter gets stuck in Neutral often. The Entire Dash and instrument cluster goes black during driving and will not come back on until hours later even after the vehicle has been turned off and back on. This has caused me to be unable to see my speed, turn signals, fuel gauges or any engine controls. This leaves me unable to operate or control my vehicle. This is a huge safety issue when driving as I am unable to determine my speed or see any of my vehicles controls or warnings. The front passenger seat motor has a horrible vibration and struggles to adjust the seat properly. I have contacted multiple dealerships on multiple occasions regarding these issues and have been told that the extended warranty will not cover any of these issues although I was told it would when I purchased. Chevy has refused to offer assistance with Towing the vehicle to a dealership when the cluster stops working and encourages me to drive a vehicle that is not operational. The service manager at one location told me this was a known issue with the vehicle.

The engine fan has been running and the check engine light has come on and upon further inspection I discovered that this is a common issue with this vehicle. I have had my vehicle inspected and serviced by Chevrolet since I purchased it and I informed the technician that there was water under my vehicle if it ran idle on several occasions and was told that it was a non issue and now that my vehicle is out of warranty there is an issue with the same thing I have been concerned about.

265 ./ 45 R21 on our 2022 Blazer AWD Premier. I have the tires rotated every 10,000 miles and the vehicle only has 30,600 miles and all 4 tires have worn out, down to 2/32 or 3/32. I have owned 20+ GM vehicles over the past 25 years and I have never had to replace a tire due to tread wear before 45,000-50,000 miles. This is an expensive mid-range SUV and should not have junk tires. It is also my first GM vehicle that has Continental tires. The replacement Continental tire is $370 each. These are expensive tires and the SUV costs more that $55K, this is not ok. I see there is one other complaint filled for tires, but most consumers don’t know this web site exists. I would not except we I called Chevy customer service, they recommend that i file a complaint. I also don’t think most Blazers have 21 tires, i order this vehicle from Chevy with this as an upgrade option. Please research this tire brand and model as well as 2022 Blazer AWD Premiers with 21 tires an i think you will see this is a pervasive problem. Thank you.

To whom it may concern; my son's fiancé was driving on the highway and the vehicle had a sudden loss of power. Afterward, it turned off and would not re-start. After towing the vehicle to a repair facility (out of warranty by mileage, 45K) were advised they retrieved DTC P023F and advised the fuel pump control module failed. I did some checking and found that GM is aware of the issue and has released T.S.B. #PIP5964C, which states "CRANK NO START, STALLING, LOSS OF POWER, FUEL GAUGE INOPERATIVE/ERRATIC, MALFUNCTION INDICATOR LAMP (MIL) ILLUMINATED P023F P129F". Fortunately nothing happened, she is young and smart and was able to handle the situation without incident. However, I shutter to think if my father in-law would have been driving, and/or any individual who would have panicked.

The lift gate on my vehicle closed suddenly and for no apparent reason as I was loading groceries into the vehicle. The lift gate hit me in the back of the head and did NOT retract/open upon contact. I had to quickly lift the lift gate with both hands to get out of the way and press the button for the lift gate to open. A couple of minutes later, the lift gate again closed suddenly and for no apparent reason; however, I was not hurt the second time and was able to move out of the way and press the button to stop/open the lift gate.

My transmission started slipping really badly. Had never happened before, and then suddenly wouldn’t shift above 3rd gear. My reverse gear stopped working. I had to have my valve body replaced which fixed the drive gears but the reverse still didn’t work. After months without my car, my dealership had to replace the transmission.
