2020 Honda Ridgeline Problems

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.

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.

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.

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.

I own a 2020 Honda ridgeline pick up truck. For many months, I have been aware of an existing recall on the rear view camera tailgate wire harness and have received two notices. I have been at the dealer twice to have it repaired, the last time of which they canceled my appointment the day before the repair saying they don’t have any parts and that I will hear sometime Late fall. Honda has been aware of this problem with the rear camera tailgate wire harness because of recalls on the 2017 through 2019 models. That I have received two recall notices already with Honda claiming they don’t have the parts to fix it is ridiculous. Their dilatory conduct in fixing this defect is a definite safety concern. My rearview camera does not work and Honda has failed to timely fix it pursuant to recall 24V-321.

Side view mirrors were replaced for a recall. Replacement drivers side mirror was wavy and distorted. Made me not want to use it. More dangerous to drive not wanting to use that mirror.

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).

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.

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.

Sudden spontaneous moonroof explosion. Traveling at approximately 60mph I experienced a spontaneous explosion of the moonroof while it was closed and the headliner was closed. Glass flew into following traffic. There was no oncoming traffic and we were not following anyone. Sky’s were clear and the road was dry and paved. This was a loud and distracting event and if the headliner cover wasn’t closed it could have been much more serious. This happened around 10am MDT yesterday June 25 2023. The vehicle had about 20300 miles on the odometer.

Since buying this vehicle new, on multiple occasions the automatic braking system has come on approaching other vehicles on a straight stretch of highway even when both I and the approaching vehicle are nowhere near the center line or anywhere near an accident situation. I reported this to the dealership in the first six months after purchase and was told nothing was wrong. The frequency of this happening seems to be increasing.

While driving on the highway truck pressed brakes without any obstacles near or in front of me. This event has happened more than once as of late.

Same thing they told me at Honda Mossy Lemon Grove that corrosion and rust are not warranted by Honda.
