Chevrolet Colorado Cab Chassis 2017 — Problemas relatados

I purchased a new 2017 Chevrolet Colorado on XXX. On about XXX the truck started shuddering or not shifting correctly. I took my truck to the local dealer [XXX] GM. There the diagnosed the problem to be the torque converter. According to what they told me GM instructed them to drain and replace the transmission fluid. GM knew the 8-speed transmission had a design defect in the torque converter. The torque converter clutch fails to engage smoothly, creating the shudder vibration. A fluid flush treats the symptom, not the cause. GM was permitted to put a band aid on a problem to get the vehicle through any warranty and make it not their responsible. The vehicle was returned to me, even after I complained to the dealer that this was not fixing the problem. And the truck continued to have a pause in the shifting. On about XXX the shuddering became much more apparent. I made an appointment with this same dealer that had done all of my service. On about XXX they did confirm the the problem was the torque converter. At this point the truck was no longer under the warranty, so GM had succeeded in putting the replacement of the faulty torque converter on me the consumer. As a consumer I feel I have been failed by a system we have in place to protect consumers from dishonest Corporate transactions. This process cost me $4000.00 out of pocket, and 11 days without the use of my truck. All of this transpired, because GM decided to not do what was right and fix what they knew was defective.

Transmission fluid flushing. Hard gear shift at slow speeds. Transmission shudder at high speeds

See attached document for complaint.

The contact owns a 2017 Chevrolet Colorado. The contact stated that while driving at an undisclosed speed, the vehicle shuddered and vibrated abnormally. The vehicle was taken to the local dealer, and the contact was made aware of a technical service bulletin which included replacing the transmission fluid. The transmission fluid was replaced, and the vehicle was repaired. The contact stated that recently the transmission started slipping and the vehicle was taken to the local dealer to be diagnosed. The dealer determined that the transmission torque converter and the transmission valve body needed to be replaced. The vehicle was not yet repaired. The manufacturer was not contacted about the failure. The failure mileage was 39,200.

There is a major fuel line leak just before the high pressure fuel pump. It appears that the fuel line aggressively rubbed against an A/C line component (looks like a muffler/canister). This rubbing created a huge hole in the high pressure fuel line, causing diesel to spray everywhere on the driver side of the engine compartment. This causes a massive safety issue due to diesel fuel uncontrollably spraying onto hot engine components. In my own research, this seems to be a known problem for GM. I believe there is a TSB published for this exact problem, but I have yet to find the document online. This needs to be an official recalled item ASAP.

Thermostat is having problems. Fan runs over use and Thermostat will not open

On or about 02/09/2026, the vehicle experienced a catastrophic failure directly related to a known defect identified in Technical Service Bulletin 19-NA-066. The engine "sucked" in the oil filter due to a poor design on GM's part. The stand pipe was not present apparently, and must have broken off at some point. This bulletin acknowledges an issue affecting this vehicle platform. This should have been recalled to address this engineering flaw that GM acknowledged in their TSB. Despite multiple attempts and ongoing communication with authorized representatives to have the vehicles engine replaced under an extended warranty, the vehicle was inoperable and unusable, causing significant financial hardship. I owned the vehicle for approximately 5 months and had the vehicle in the shop multiple times for other repair issues that were known per forums from other owners of this model/year of vehicle. I have exhausted all reasonable efforts to resolve this matter through dealership, GM customer service channels, and GM's executive team without satisfactory resolution. As a direct result of this defect and resulting failure, I have incurred the following damages: Loss of use of the vehicle ($24,578 purchase price on 09/20/2025) Rental and alternative transportation expenses ($90.58 rental vehicle from 02/12/2026 - 02/14/2026) Diminished vehicle value ($24,578 - $12,000 (Selling Price) = $12,578) Out-of-pocket diagnostic and related expenses ($2,036.50) Total loss and seeking reimbursement: $14,705.08

On Wednesday, February 18th, I was driving on the freeway, usual heavy traffic right off of it at 5:00pm. When exiting and merging onto the street, I pressed on my break to slow down and meet the speed of traffic, but my breaks felt hard, I struggled pressing it down, and my car wasn’t slowing down. I was able to swerve off into a dirt patch next to the road. Then I panicked, unable to find where my emergency break was, I put my car in park and it eventually came to a stop. I then took the car to the dealership, and they’ve told me that the vacuum pump needs a replacement. The car has currently been at the dealership for a week and a half and there still seems to be no solution. I’ve reached out to General Motors and with the responses they’ve given me, it feels like they the know what’s going on but have thus far given me the run around. They say they’ve reached out to the dealership, but when I mention it to my dealership advisor, they say they haven’t heard anything.

The heating blend door broke making the heater unusable. I cant defrost/defog my windows to see in February in New york...its a very common problem with this vehicle and the cost to repair is over 3000

Infotainment system will start changing on the screen to navigation and also on the odometer screen to audio settings. After turning vehicle off it will seem like a reset then do it again. A big distraction. Has done this multiple times in the last 3 months.

Transmission hard shift. Sputters when driving

On Sep 14th 2025 with KM 41959km, after turn on my colorado, after I filled the fuel tank, I had driven more of 50 min, a message appears in the screen control: Failed braking system 100km/h Max Velocity and a second message appears: Provide service to ESC. Then turn off the colorado, wait some seconds and turn on again, no messages appears. So I continue driving normally until Dec 21st 2025 with KM 47200km driving on a boulevard, I did stop two times due to traffic, automatic start/stop activate, in the second stop when start on again same message appears: Failed braking system 100km/h Max, I felt the brakes not responding, my colorado stopped over a greater distance. If I hadn't maintained a safe following distance, I wouldn't have been able to stop in time and I would have crashed into other vehicle. I arrived on home safe but nervous. At next day, Dec 22th turn on my colorado and appears same message, KM 47245km I turned off and tried turn on again but it not turn on, battery low message appeared, then I had to have my Colorado towed to the car dealership. It is on revision waiting a diagnosis. I hope you can analysis this issue. Thanks

October 2025----problem with 2017 Chevrolet Colorado WT with 2.5L engine and 6 speed automatic. It has 57,000 miles on it. Original owner--bought new. "StabiliTrak" warning light came on when I first started the pickup in the morning and stayed on. Then a message appeared saying that there could be a steering issue or a control issue operating the pickup and to take it to the dealer for service. Colorado starts normally and runs normally. Only issue is the warning light for the StabiliTrak is on constantly. I read in the manual that TCS(traction control system) and the StabiliTrak system have been disabled. The owner's manual states "The vehicle is safe to drive; however, you do not have the benefit of StabiliTrak, so reduce your speed and drive accordingly." Have a dealer service the system. I have had no safety issues or risky situations. Have about 300 miles added since it occurred. It has not been inspected yet by a dealer.

2017 Chevrolet Colorado pickup with 58,000 miles. Check engine light came on. Scanner reading by a repair shop indicated a EVAP issue. I declined the $1200 repair estimate. I paid for diagnosis of problem $200. I repaired the system by "cleaning 2 filters at the beginning of the fuel tank ventilation system. The "primary filter and hose are located in a especially dusty area on the pickup truck and is prong to plugging if regularly driven on rural gravel roads. Nothing in the owner's manual indicates the service is required of this filter. FILTER SHOULD BE RELOCATED TO ENGINE BAY. Check engine light was reset and has not come back on. NOTE: This is part of the pollution equipment that stopped working properly before 10yr. or 100,00 miles.

Fuel leak. Engine stop the truck, smell of fuel in the cabin, the truck is using diesel. This started in Ictober, technician told me it’s the gas pump. Still the smell in the cabin and now lights on dashboard alerting failure in the system,

I cuts out and shuts off driving in a parking lot at 10 miles an hr and while driving on the freeway going 65. Started 6 months ago but has gotten worse. The computer system on dash goes black and will start randomly changing stations, or freeze and now it's changing on the steering column and engine light is on

I believe there should be a recall for the KNOWN chafing issues for the engine wire harness. This happened to my truck this past year around September/November of 2024 and didn't get a fix until June 25. There are TSB's out for other models as well as mine regarding the wire chaffing. it shorts out intermittently and cause all kinds of warning lights to go off, (check stabilitrak, check 4x4, etc) the vehicle usually did a bunch of stop and go jerks when it would do this then go into limp mode. I even had it stall completely on me and the steering wheel locked up. I think they had to disconnect the battery or something to get the key out. I've been on several different forum pages trying to find the issue and I have seen it happen on relatively new vehicles as well. Lucky for them they are under warranty but dealers still giving them a hard time on this issue. I believe this poses a safety issue and there should be a recall on this. Besides that, no one should have a perfectly good vehicle and have to pay 4000-7000 dollars to replace a wire harness because of a manufacturer design defect which seems will eventually cause this issue though it had happened on newer models as well. the bulletin #specific to my vehicle is PIT5626D but there are other bulletins for other engines/models

Received a P2138 Throttle/Pedal position sensor/switch "D"/"E" voltage correlation code while driving that caused "Reduced Power" and "stabilitrak" errors. The reduced power mode it went into made the truck unable to accelerate in a safe manner and made the truck "jump" wildly as it attempted to accelerate.

The vehicle shakes aggressively when you speed up. We took it in and it’s a transmission issue. There have been thousands of similar complaints from other owners but Chevy refuses to acknowledge it and issue a recall.

The contact owns a 2017 Chevrolet Colorado. The contact stated while driving at an undisclosed speed, the transmission converter clutch was shuddering. The contact stated that the failure persisted. There were no warning lights illuminated. The vehicle was taken to the local dealer where it was diagnosed that the torque converter and a fluid change were needed. The vehicle was not repaired. The manufacturer was contacted and offered to assist with the cost of the repair. The failure mileage was approximately 38,000.

The transmission jerking @ or skipping.

DESCONOCIDO. El volante se puso duro cuando me echaba de reversa para estacionar,

My son was driving the vehicle when it lost power and he had to maneauver to the side of the road putting himself and others in danger. The truck was not able to drive forward, but could only drive in reverse. There were no warning lights or other indications that the vehicle had a problem. I had it towed to a mechanic who said Chevy Colorados have problems with their transmissions and it would need to be replaced.

The heating cooling blend door broke as it's made of cheap plastic. Doing research on this defect it's very common ...in this year vehicle as well as in the gmc canyon...it's a manufacturer defect. And makes it impossible to defrost/defog your windshield without fixing it...and average cost to replace is 1700.00- 2300.00...due to labor cost...part itself only costs around 100.00....that's an astronomical amount of money to fix something...that is a defect and you can't safely drive without it!

The contact owns a 2017 Chevrolet Colorado. The contact stated that while the vehicle was parked, the key was difficult to remove from the ignition. The failure occurred on several different occasions. No warning light was illuminated. The vehicle was drivable and was taken back to the residence. A dealer was not contacted. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 70,000.

I was driving to lunch and without warning, my brakes failed when I approached a 4-way stop. With ABS, I was able to stop my vehicle safely in a parking lot. However, the when I turned the vehicle off, it would not start again. The vacuum pump seized and since it is driven by the exhaust camshaft, it destroyed the exhaust camshaft. It's been two weeks and I have been unable to acquire that part. I have been notified by GM parts distributors that the part is on a national supply delay with no firm ETA from GM. It seems to be a very common failure. I have been out of a vehicle for over two weeks because of this failure. I also could have been in a terrible accident since the vacuum pump failed without warning. I have checked chevy forums and several others reported the same issue.

The parking brake lever contacts a piece of the wiring harness/bundle during operation. Wear on the wiring lead to exposed wires in the bundle. For me, this resulted in an electrical short that rendered the dashboard inoperable. This is a safety hazard as the entire dashboard becomes inoperable, and also a potential fire hazard.

The contact owns a 2017 Chevrolet Colorado. The contact stated that the air bag warning light was illuminated. The contact stated that the seat belt warning light illuminated while the seat was not occupied. While driving at various speeds, the engine overheated. The coolant reservoir was empty, but there was no indication of a leak. The fan was operational, but the vehicle continued to overheat. The vehicle was taken to an independent mechanic, who informed the contact about the operation of the fan. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 110,000.

Fuel leak in line. There is a pin hole in the line spewing fuel under pressure when running. The fuel flows down the side of the tank as I reported in Complaint Number 11587383 on May 7th, 2024. Now I have removed the bed to discover said leak. Adding picture of the leak spewing fuel from line, by "P E" lettering on the line This is a major concern as any flame near the vehicle would cause it to go up in flames. The manufacturer should correct this problem. I see no reason why this hard plastic pipe developed a hole. It is product defect.

* Smell gas and discover leaking down driver side of fuel tank after parking, so something on top. Maybe fuel pump or ?. It is available for inspection. *Fuel puddle under vehicle in parking lot. *Have not contacted dealer, just noticed and found lots of others with same issue online with the Chevy Colorado and GMC Canyon. *I am the only one who has inspected to date. *No warning of any kinds, except stepping out of truck and heavy GAS smell, and seeing a shine of color in the rain water going to parking lot drain.

Truck started having electrical issue after finding a dead squirrel in the engine. Taken to dealership 9/2/2023 and was told the wiring harness needed replacement. Left the truck there for 2.5 months with no repair so we brought the truck home in December 2023 and asked them to call us when they got the part. Had a rainstorm the following day and the truck tried to start itself, wipers running, lights flashing, and smell of something burning. Disconnected the battery and had truck towed to Beach Chevrolet Dealership. Damage was worse than they originally thought and we still needed a new wiring harness. That particular wiring harness has been discontinued by GM and they are unable to find the part anywhere. The truck is still at the dealership and it will be 8 months on May 2, 2024. State Farm refuses to total the truck and we have no idea when our vehicle will be repaired. Have contacted GM customer Disservice repeatedly with no resolution in site. What recourse do we have?

Power steering stops working on and off out of no where no engine light until power steering is actually not working. Transmission shudders also which both are known issues to these year model trucks.

Front Passenger airbag always showing it is "OFF" whether someone is sitting in seat or not. The dealer wouldn't fix this unless I paid a diagnostic fee of $185. Also Radio infotainment system doesn't respond to touch, however it has a mind of its own, blaring radio volume up and changing channels on its own. Very distressing and distracting while driving. Also a $185 diagnostic for looking at this as well. I had purchased an extended warranty and extended maintenance agreement. The dealer told me they won't fix it unless I pay for the diagnostics and they won't have the extended warranty company fix it under my original extention warranty agreement. This all happened before my vehicle had 26000 miles.
