The contact owns a 2020 Honda Ridgeline. The contact stated that while driving at an undisclosed speed, an abnormal knocking sound was heard, and smoke emerged from under the hood. No warning lights illuminated, and the engine failed. The vehicle was towed to a dealer, but was not inspected. The vehicle was then towed to another dealer, where it was diagnosed with a failed engine. The dealer informed the contact that a piston went through the engine and advised that the engine needed to be replaced. The vehicle was not repaired. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The dealer offered to replace the engine with a salvaged engine and cover the repair under warranty; however, the contact declined the repair and requested a new engine, which was denied. The manufacturer was notified of the failure, and a case was filed. The failure mileage was approximately 80,000.

When driving normally, oncominng traffic is triggering the frontal collision warning system. Is some cases long enough to start the emergency braking procedure if I do not engage the brakes manually preventing the automatic emergency braking. This usually happens on curves in the road in typically right hand curves. This is happening on 2 lane roads at between 45 and 55 mph. Initiating and emergency braking at this speed could send my car into the oncoming traffic. I am concerned for my safety if I do not hit the brakes manually.

The vehicle's front-facing monocular camera experienced an internal component failure that triggered a permanent error code U3000-49. This hardware failure instantly disabled multiple core safety features simultaneously, including the Adaptive Cruise Control, Lane Keeping Assist (LKAS), Road Departure Mitigation, and Collision Mitigation Braking System (CMBS) ABS Braking and High Beam Support with all dash lights remaining on. The sudden, unexpected loss of automatic safety braking and driver-assist features while moving poses an immediate highway safety risk.

The vehicle's Auto-Idle Stop (AIS) feature is defective and creates a severe safety hazard. While stopped at a busy road intersection, the feature engaged and shut the engine off normally. However, when releasing the brake pedal to proceed, the engine glitched and completely failed to restart, leaving the vehicle completely stalled, unpowered, and stranded in live traffic. The vehicle became a sitting duck in the intersection. This is a recurring issue that requires a complete ignition power cycle to recover, posing an immediate risk of a rear-end or side-impact collision. It happens most often under heavy load. Hot day with AC on, or Cold day with Heater on and seat warmers. Dealer ignored or failed to re-create at first because it was intermittent. I've been through SOFTWARE UPDATE, STARTER, RELAY REPLACEMENT AND VALVE ADJUSTMENTS (twice) and a new BATTERY over several years and it still stalls. It's dangerous and terrifying to be immobilized in traffic when it won't start.

The contact owns a 2020 Honda Ridgeline. The contact stated that while driving 65 MPH, there was a misfire coming from the engine with the check engine warning light illuminated. The contact pulled over to the side of the road and, upon inspection, the contact determined that one of the ignition coils had failed. The contact purchased a new ignition coil, replaced the part, and resumed driving; however, the vehicle made an abnormal rattling sound while driving. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the engine had failed due to a loosened connecting rod and needed to be replaced. The contact ordered a new engine. The vehicle was not yet repaired. The manufacturer was not contacted. The failure mileage was approximately 118,000.

2020 Honda Ridgeline-Internal failure, multi purpose camera. Multiple lights on dashboard and codes associated with driving support system, Collision Mitigation, Braking System, Lane keeping assist system, Road departure mitigation, Transmission System error. All these are showing up because of the front camera going out due to overheating. Dealership quoted $1197.20 for replacement. Multiple safety violations making vehicle unsafe to drive. Extended warranty will not cover.

BCM module failure. Keyless entry error. Vehicle dashboard lit up with many errors. Car alarm went on and off. Car will not start . Disconnect battery toe reset. Drove home and the car doesn’t want to stop running or idling. Disconnect battery till it turns off.

The contact owns a 2020 Honda Ridgeline. The contact received notifications of NHTSA Campaign Numbers: 26V365000 (STRUCTURE, SUSPENSION) and 26V332000 (AIR BAGS); however, the parts to do the recall repairs were not yet available. The vehicle was taken to the dealer, and the contact was informed that the bolt set needed to perform the suspension recall repair, and the parts needed to perform the air bags recall repair were not yet available. The contact stated that the dealer had expressed frustrations due to a lack of support from the manufacturer. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue, but no assistance was provided. The contact had not experienced a failure.

My vehicle has safety recall, I contacted twice Honda Dealer and I was informed that part has been ordered. It has been timer a year, but so far no update.

While stopped in heavy traffic at a traffic signal, the engine stopped and would not restart. This was due to the AIS system. The car became disabled in heavy traffic. I was only a few feet from the entrance to a gas station, however due to the interlock system that locks the transmission in Park, the truck could not be pushed out of traffic. Honda, unlike other manufacturers the use the same transmission, does NOT supply an emergency over ride to get the transmission out of park ( hazard). After a few minutes of sitting in heavy traffic and nearly. wing hit by fast moving cars, the engine did restart. This is not the first time this has happened. The dealership is over 100 miles drive to have to checked (r/t).

Connecting rod/bearing failure.

After parking on the roadside with engine off for about 10 minutes, the truck would not start. I tried to start twice; the dash lights came on, I could hear the starter try to engage, felt a slight forward lurch from the vehicle, then nothing. The starter seemed to disengage' the dash lights stayed on, and the electric system went into ACC mode. I tried twice with same result. I attempted to put the shift selector in neutral, but it stayed in Park. I was seated in truck, seat belt on, foot pressing on brake pedal. After waiting a few minutes, it cranked and started normally. No further issues the rest of the day. The weather was mild, sunny, temperatures in the mid-60’s fahrenheit.

Stranded in traffic unable to start almost got rearend because the start-stop died and to cycle to park to get it started. This has happen on more than one time.

Spun Rod Bearing at 70,000 miles. Truck will need a new Short Block. Truck has been at the dealer for all recommended service and oil changes.

Auto stop start does not work properly in this vehicle after repeated fixes by Honda and dealership. Vehicle sometimes does not restart after stop start engaged at stop causing a stall like event. Auto stop start tries to start vehicle after stop but vehicle either stalls/fails to restart or is extremely slow to restart. Vehicle has been repaired, new starter, new battery, new relays less than one year ago and vehicle is now experiencing the same issues. Owner (me) is now disabling feature every time vehicle is started to prevent system from engaging.

Dealership has not completed NHTSA Recall Number24V-064 Honda dealer is saying they do not have parts to perform this recall.

The rod bearings had failed on cylinders 3,5, and 6 at 140 thousand miles with proper mantice being done to it. This has been confirmed by the dealer Honda Maryslviie in Maryslive, Ohio. The vehicle has just been looked at by the dealer. No warning lamps but just started to hear knocking in the engine.

The contact owns a 2020 Honda Ridgeline. The contact stated that while the vehicle was parked or while driving, there was a loud knocking sound coming from the engine compartment. There were no warning lights illuminated. The vehicle was taken to the dealer, where it was diagnosed that three rod bearings and that cylinders #3, #5, and #6 had failed. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was opened. The approximate failure mileage was 140,000.

1. Visibility: rearview mirrors/devices: exterior. Driver mirror fell off. 2. Windshield multipurpose camera unit, u3000-49, burned out. Requiring replacement within 4 years of purchase. 3. The auto idle stop stalls the car.

While stopped at a traffic light on a state highway the idle stop did shut off the engine. When the light turned green, I released the brake, but the engine did not crank or start. After placing transmission into Park, I attempted to start normally. There was no response to the start button being pushed, other than all the typical pre-start warning lights check on the panel. Tried to start with transmission selector in Neutral..same result. All doors and hood was closed, driver in seat, belt fastened, and key nearby. I attempted to get out and push the truck to the side of road with assistance. Unable to do that because of the transmission park interconnect. After about 3 minutes trying multiple times to start the engine, it finally did start normally. The vehicle battery is pretty new and checking the voltage at home, it is fine. This is a dangerous situation. This “ Idle stop” system is senseless and a safety hazard. I have not received any notice from Honda about any recall on this system.

The contact owns a 2020 Honda Ridgeline. The contact received notification of NHTSA Campaign Number: 24V064000 (Air Bags); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact had not experienced a failure.

Truck stalls repeatedly at intersections due to failure of ignition to restart after stop signs or stoplights. Warning lights come on and complete restart is required. Other motorists become agitated.

My 2020 Honda Ridgeline has an Auto Idle/Start system. The truck engine turns off when it stops, then automatically turns on when brake is released or gas pedal pressed. There was a Honda notice issued that the system may not automatically restart. A fix (software update) from Honda was implemented on my truck on 03/29/23. This "fix" did not work. On 09/05/25 at 1:25 pm I pulled up to an intersection. The Auto Idle system automatically turned off the engine as intended. About 2 minutes later, when the brake was released and gas pedal pressed, the engine did not restart. The truck stalled. Various efforts (~ 1 minute of panic) ensued to start the engine. Eventually, put the truck in park, waited, then started the engine. This situation occurred during high traffic at a busy intersection. It caused other drivers to take risks pulling out in front of other cars to get around my stalled vehicle. It was a very dangerous situation. A class action lawsuit was filed against Honda about this. Honda claims their software update fixed the problem. My scary experience shows that it did not fix the issue. Their auto idle/start system is simply unsafe. Also, it is not possible to permanently disable it.

Auto start stop fails to work.

Multi purpose camera behind front mirror failed. Most safety systems will not work. Various warnings regarding system failure were noted on dash. Supposedly a bad battery installed and warranted by dealer caused this problem? Dealer covered the battery but charged $2100.00 to replace the camera!

Auto Idle Stop system is not working correctly. Usual it happens at a traffic light, the truck Auto Idle Stop system sometimes will not start the engine and requires me to put it in park and restart with the primary starter. Took the truck to Honda dealer and they told me the best remedy was to turn off the Auto Idle Stop system every time I use the truck. This does not seem like a reasonable fix. I have had the truck or 5 years, but only have about 26000 miles on the vehicle.The Auto Idle Stop system has failed to work approximately 15 to 20 times since I bought the truck new in 2020.

AIS system not working properly . Vehicle stalls when brake is applied when car is stopped and at idle. Does not restart when brake is released as designed . This creates a safety hazard when in traffic . This has occurred frequently . Automatic Idle Stop/Start (AIS) System

On several occasions (>5) the engine had delayed starting after the auto engine stop feature engaged (when idling). After the engine didn’t start… we attempted to start by pressing start/stop button with no immediate response. Typical time to restart the engine is approximately 5-10 seconds. On one occasion it took 5 minutes. Apologize for lack of very specific information but when this occurs it causes some level of panic especially when you are in traffic. We have been disabling the feature as a habit since 2021. On rare occasions when we forget to disable the feature I would estimate that there is a ~50% chance we will encounter a delayed start issue.

My Honda 2020 ridgeline has intermittent faults on the dash monitor, it displays ACC, LKAS, Collision Mitigation, High beam, lane departure warnings, and sometimes transmission problem. I am told it is the muti cable assembly sensor on the front window not communicating with the other sensors. I took my car to auto zone and they stated no communication, due to a bad battery. I replaced the battery, and it still has the multiple errors/ fault codes. During research several people have had this problem with Honda vehicles. At times it goes away for a day or two and then comes back with the same faults. It seems like a faulty part. The dealer wants 1800 for repair and calibration of sensors, this was after they ran a diagnostic test and found no engine faults/codes.

The visor on the drivers side will not assume the position so that it does not interfere with complete visibility of the front window. It was hard to adjust when we first bought the car and we thought it would get less stiff but it hasn’t.

My Ridgeline has stalled during normal operation 3 times. The 1st was in April 2024, and the latest was this week. All three times it stalled when accelerating after a traffic stop. The first was at a stop sign at the bottom of a hill. The second was at a traffic light, it should be noted that the start/stop was "off" on this incident. And the latest incident was during stop and go traffic on the highway. * Yes - available for inspection. * Safety - could be a safety issue when a vehicle doesn't operate in a normal manner. * Dealer/Others - no I haven't had it inspected, I have been monitoring this issue on the internet. * Symptoms - there were none before the incidents

Whenever I’m driving in my vehicle everything seems to be fine until I stop at a red light. On three separate occasions, while my vehicle is stopped it will automatically go into neutral and stall. This causes my truck not to run properly. I have to shut my car off, and then turn it back on to put it in drive and operate it like normal. I’m unsure what my cars issue is but it is an inconvenience and a safety concern due to it keeps happening while in traffic.

My rear camera failed again. The vehicle was recalled for rear camera failures and a supposed better cable was installed. In less than a year it failed again. So I once again are without a rear camera even though it was recalled and repaired. The repair apparently didn't work.

In then last 6 months my Honda Ridgeline fell to restart engine at the stoplight 7 times

In response to a recall for the possible failure of the rear camera, I had the Honda dealership make the repair. Upon receiving my vehicle, I noticed that the wiring bundle had numerous small gauge wires exposed. I photographed them and corresponded with the dealership. They said they’d rectify my concerns. After visiting the dealership again for yet another recall concerning front passenger seat sensors, I was informed that the wiring issue was standard Honda practice and I should contact Honda. I filed a complaint with Honda and I just heard from them by phone and I was told they don’t consider exposed wires running from the bed to a tailgate a safety concern. I had checked two additional model years of the Honda Ridgeline(22 and 25) and found the same unshielded situation. Certainly a design flaw and a safety situation. Honda intends to do nothing although there is an active recall for rear camera failures. A truck bed is used to carry all kinds of things and unprotected wiring to vital components is unacceptable.

Regarding 2020 Honda Ridgeline, we have two issues. In December 2024, the auto stop / start feature started working intermittently and then a few months later ceased to work entirely ceased to work. In May 2025, we got two error messages on the dashboard. One was for transmission error. The second was for emissions error. There were no apparent mechanical issues with the truck shifting gears when we brought it to our local mechanic 2 miles away and to the dealer approximately 5 miles away. We brought it to our local mechanic who said it was the solenoid in the transmission and would cost around $7000 for parts and labor since Honda didn't sell only the brain and we would have to purchase the entire transmission. We brought it to Norm Reeves Honda (the largest Honda dealer in the United States) who confirmed this root cause mentioning "MIL" and "Solenoid" specifically. Norm Reeves Service Technician said it would cost around $9000 parts and labor. We logged a case #15593XXX with Honda Motor Corporation who auto-responded to our email saying, "Please note, due to a recent influx of inquiries, our response time will be delayed. Please do not submit multiple inquiries as this can lead to further delays in case handling." An internet search for Honda Ridgeline Service Bulletins uncovered Service Bulletin #A23-091 for what sounds like one of these two issues. It has been more than 3 days since the "inquiry" to Honda and we have yet to receive any response. Norm Reeves said they will start to charge us a storage fee of $35 USD a day if we do not pick up the vehicle by Saturday EOD.

My auto start/stop wouldn’t restart my car in traffic. I ran the battery down trying to restart it and finally had to jump it off
