2020 Honda Ridgeline

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).

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.

Connecting rod/bearing failure.

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.

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.

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

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.

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.

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.

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.

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.

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!

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.

The contact did not have the report number. The contact stated that the EMT team was not called. The contact stated that she had bruises on her knees and abdomen, and she had 2 bumps on the right and left sides of her head. The contact stated that she later went to see her doctor. The contact stated she was able to drive the vehicle to her residence. The contact had taken the vehicle to a collision repair shop. The vehicle was not yet repaired. The manufacturer was informed of the failure. The failure mileage was approximately 65,000.

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.

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

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.

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.
