Electrical System Problems of Honda Ridgeline - part 1

I had the backup camera harness recall performed on my 2018 Honda Ridgeline on 09/06/2023 by Honda of escondido , CA. (see attached invoice of recall work performed. ) on 01/27/2026, the backup camera failed to appear on the dash screen when the vehicle was in reverse. I restarted the vehicle and the camera view was still not visible on the screen. I drove home and parked the vehicle in my garage. I turned the ignition off and then on again and put the car in reverse with the brake applied. This time the camera view was displayed on the dash screen. Appears to be an intermittent problem. (see attached two pictures of rear camera view not projected to the dash screen and one picture of my vehicle"s mileage, 50,518 miles. ).

The vehicle’s engine and powertrain management system repeatedly fails with multiple dtc's triggering a full-system cascade of safety-critical warnings and automatic power-limiting. The issue affects the engine, transmission, emissions, awd, brake system, stability assist, steering assist, abs/vsa, hill-start assist. The vehicle is fully available for inspection upon request. During each failure, the vehicle abruptly enters reduced-power “limp mode” without warning—resulting in loss of engine power, disabled awd, and disables all safety/stability systems. These events have occurred in normal traffic, including at red lights and in intersections, creating a risk of rear-end collisions, inability to accelerate, and loss of vehicle control. I transport an autistic child, making reliability and predictable vehicle behavior critical to passenger safety as well. The problem has been reproduced and documented by multiple authorized Honda dealerships. The vehicle has now undergone 13 repair attempts in the first 14 months of ownership, across 6 different Honda dealerships. All have been unable to diagnose or permanently repair the defect. The vehicle has been repeatedly inspected by Honda technicians, who escalated the issue to Honda tech line. Tech line documents (dated 10/1/25) show that no aftermarket modifications exist and that the failure is verified but intermittent and ongoing. Warning lamps / symptoms: each failure event triggers a full dashboard sweep including: – awd system problem – emissions system problem – transmission system problem – power steering system problem – vehicle stability assist problem – hill start assist problem – brake system warning – road departure mitigation problem – blind spot information system problem there is a federal lawsuit filed filed in oregon district court case 6:25-cv-02142-ap.

I took my vehicle to the Honda dealership to have a safety recall repaired. Following the repair, the alarm started intermittently going off. Before the repair, the vehicle was running well. I did not know what the alarm sounded like before the recall repair. After they checked the vehicle, I was hit with a $1500 repair bill to replace the keyless control unit. This part is what is causing the issue. Now I am left with no recourse. I called Honda corporate, and they told me that they couldn't help me. I am very disappointed because I am a long-time Honda owner and apprantly the quality is not there anymore.

The contact owns a 2018 Honda Ridgeline. The contact stated that while driving approximately 50-55 mph on I-40 westbound to I-25 and making a turn in a construction zone, the passenger’s side air bag deployed without warning or impact to the vehicle. There were no reported injuries. The air bag control message was displayed after the failure. Two days later, the system indicators produced a failure with the road departure mitigation, collision mitigation, trailer stability control field assist, vehicle stability control, power steering, air bag system, and adaptive cruise control. The brake system warning light was illuminated after the parking brake was released. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was approximately 56,850.

Auto start/stop malfunction. On two occasions the auto start/stop has shut the engine off at a stop light and after releasing the brake the vehicle went completely dead. Dashboard/radio and all electronics dead. After multiple attempts the vehicle finally restarted. Now the normal start is sluggish like a low battery. Battery was replaced under warranty and check out multiple times by the dealership with them not able to find any issues.

My vehicle just reached 101,000 miles and is having engine problems, vehicle will not accelerate past 40mph which is really unsafe, I saw a article that this was a common issue on the 2017 model.

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.

I bought a new 2025 Honda Ridgeline truck from hendrick Honda, easley, SC and within the first 24 hours the instrument display showed an “auto idle stop error” and to get service at the dealer. I took it back to the dealer within two days, and they said they ran diagnostics and couldn’t find nothing wrong. The service advisor said “it will probably just go away as you drive it more. ” well, after a couple thousand miles now, it has not gone away but sporadically reappears while driving. I called the service advisor back and he said I could bring the truck back and they could try a diagnostic test again. I asked him to instead contact Honda automotive as this is a known issue with the Ridgeline then call me back to notify me of the solution. He never called back.

Rvc rearview camera is not functioning.

See all problems of the 2023 Honda Ridgeline 🔎.

The rearview camera continues to fail after recall for the issue was completed. Estimate 6 months+ since recall was performed to replace camera tailgate wire harness. It has begun random failures again. There is no indication from the dash of an error. When placed in reverse, the camera display in the dash goes nearly black or totally black; sometimes lane back lines are present, sometimes not. The current problem is entirely consistent with the failure conditions and symptoms prior to the recall update to replace the wire harness. The problem can fairly routinely be triggered by multiple uses of the dual-action tailgate movement. A few flat down and back up, then a few swing-gate actions will generally trigger the failure. When the camera monitor does have a normal picture, it will stay that way indefinitely -until you again have repeated tailgate movements using the dual-action feature. It is generally possible to perform several dual-action movements of the tailgate and restore the camera monitor to a functional view. The recall and replacement with an "improved" wire harness has failed to last; the identical problem is recurring. The vehicle was at a Honda dealer today. They report no error codes, they report no continuity issues with the wire harness. Proposed remedy is to replace the camera unit, despite no error codes. The only basis seems to be that they could not "see" a problem with the harness. Nor can they explain why the circumstances are identical to what caused the initial recall, but still feel it's not the cable. Nor can they explain why my repeated movements of the tailgate can make the display work again. This is a considerable safety issue as it's extremely difficult to back up the vehicle if you can't see behind/below the tailgate. Mirrors are not enough; safe backing requires the use of the rear view camera.

While idling at a traffic light,2 systems shut down: adaptive cruise control & road departure mitigation system. Also the brake system light came on, but the brakes continued to work.

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.

The automatic high beam system is terrible. It is too sensitive so the beams flash hi/low on and off. Even a small road reflector on a dark empty road will force it back to low beam. Other cars I own with this type system work much better. It’s a safety hazard because auto hi-beam is on by default and you can’t count on it providing the correct amount of lighting when on dark roads, plus it annoys oncoming drivers because of the constant flashing.

The contact owns a 2019 Honda Ridgeline. The contact stated that while driving 30 mph, the vehicle briefly lost motive power before slamming into gear. The contact was unsure if any warning lights were illuminated. The vehicle was taken to the dealer to be diagnosed, and it was determined that the transmission needed to be replaced. The vehicle was repaired. The contact stated that on a separate occasion, while the vehicle was parked inside the garage, the horn and panic alarm activated independently, and the headlights started flashing. The contact disconnected the battery to stop the failure. The vehicle was taken to the dealer to be diagnosed. An unknown software update was performed on the vehicle. The contact stated that when the windows were completely closed, there was a musty odor inside the vehicle. The contact was unsure where the odor was coming from. The manufacturer was not notified of the failure. The failure mileage was approximately 42,000.

Auto idle stop (ais) system, a fuel-saving feature that temporarily shuts off the engine when a vehicle is at a complete stop. Drivers say that in some cases, the engine does not automatically restart, leaving vehicles stranded in traffic. Several complainants reported needing to jump-start their vehicles to get them moving again.

Vehicle started on it's own without key fob triggering the alarming system to turn on. They only way to turn both off was to disconnect the battery.

Truck was waiting at a stop light in drive mode and foot on brake pedal. When the light changed to green. I tried to accelerate to go and the whole vehicle shook/lunges forward and shut off. Vehicle went into neutral and wouldn't allow me to go into drive mode. I had to restart the vehicle twice before it allowed me to go into drive again. Vehicle was stuck in the middle of the street with oncoming/ongoing traffic. I had this vehicle at the Honda dealer(with documents) three times previous for this issue and its still not resolved. Please help.

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

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.

Keyless access control unit part number: 38320-t6z-a31 the vehicle headlights came on and dash lights flashed on and off. The alarm would also go off and on. This causes the battery to drain as well. Also I know of several other Honda Ridgeline owners who have had the same part failure.

This is a brand new 2025 Ridgeline with only 900 miles. The collision mitigation breaking system and the lane keeping assist system does not work properly on my vehicle. The dealer where I bought the vehicle (dick brooks Honda in greer) has insisted there's nothing wrong with the vehicle on two occasions. However, I took the vehicle to another dealer; the master technician said there might be something wrong with the radar system in my vehicle and to take it back to the original dealer. The original dealer won't even acknowledge what the other service department said about the radar system. Honda is just parroting what the original dealer is saying. I have a brand new vehicle that is not safe to drive and nobody is helping me. I have captured video on a gopro of some incidents when this occurs. These systems go off for no apparent reason. When I manually turn off the cmbs, there's a persistent warning message that appears on the infotainment screen entitled, cmbs problem. That message says: "the collision mitigation braking system has a problem. Restart your vehicle. If the indicator remains on, have your vehicle checked by a dealer. " the cmbs is malfunctioning, but how do I know if the system is off when I turn it off when this message appears? the dealer where I bought the vehicle from says "this is normal", but I know that is not true because I have looked at other 2025 Ridgelines and this message does not appear.

2019 Honda Ridgeline alarm started going off at random times. This is a safety concern because it causes drain on battery and could affect vehicles ability to operate . The part is the keyless entry unit located behind glove box. I had to go out to check the car in the middle of the night several times. This part has been reported and listed here under bulletin sb-21-055. Honda offered extended warranty and fixed some vehicles as reported by some Ridgeline owners. This random alarm was reported by 86 Ridgeline owners according to Ridgeline owners club. The repair cost me $957 including a $287 charge for labor- according to the nhsta bulletin sb 21-055 labor should be . 03 to . 08 hours to repair - beware of over charge for labor. Courtesy Honda of palm harbor FL. Offered $100 off when informed of the keyless entry unit history. I escalated to american Honda who offered nothing, not even goodwill discount. This is the keyless entry unit for bind Ridgeline and pilots. There is a documented issue with this part (sb 21-055) it’s a safety concern considering the draw on battery power not to mention where you are when the alarm starts blaring. This part has a known history of being faulty, has been documented with nhsta (sb 21-055) Ridgeline owners club has 86 different entries for that part alone and could effect lighting and driver assist functions considering the draw on battery power. The alarm goes off without warning or indication and happens randomly.

On 5/10/25, while driving 5 warning icons came flashing on after another. 1) emissions system problem 2)vsa systems 3) hill assist problem 4)tsa 5)power steering system problem . This 2019 Honda Ridgeline with 49272 miles ended stalling 3 xs in the middle of traffic!! frank brown Honda was called and not very helpful! I’m waiting to hear on expensive warranty what can be done. I don’t have towing so stranded at my house with the car. This was scary and upsetting!! please help if you can.

On several occasions, while driving at night, the auto dimming headlights would not dim. Last evening, on 2 different occasions , on a rural road, no road signs, mailboxs . Nothing that would cause a issues, the headlights would not go from high beam to regular (or low beam. ) 2 different times , vehicles coming at us, the lights would not dim. Time was apx 9pm , not a cloud in the sky. I had all so noticed while driving on a interstate , the same thing would happen, the lights would not dim,, drive maybe 50' or 5-10 seconds later. They would dim. There seems to be no rime or reason of if or when they will dim. We had 18 and 22 outback and they worked perfectly , where the Ridgeline has malfunctions. Asking the dealer they have not heard of anything wrong . . I have not had them to check , but have heard from other owners of the Ridgeline and they are complaining about the same thing. Uptill either the 22's or 23 models the auto dimming worked perfectly . . Then Honda changed either the location of the sensor or changed the software.

While sitting at a stop light at an extremely busy intersection, after pressing the auto idle off button in trying to keep the air conditioner running, my vehicle just completely shut down like it had a completely dead battery. I couldn’t even turn on my hazard lights. The vehicle was completely dead. After pressing the on/off button several times, power to the vehicle was restored and I was able to restart the vehicle. It reminded me of when a computer glitches and reboots on its own. By happening at an extremely busy intersection, I felt like my safety and the safety of others may have been in jeopardy if other vehicles would have made aggressive maneuvers to get around my inoperable vehicle.

Reference investigation: ea25004, no restart after auto start/stop engages 2 separate instances 1st instance during stop and go driving on highway in heavy traffic, engine failed to restart automatically after full stop, message stating something about neutral appeared, unsure exactly what message stated. I had to shift to park and hold the brake down for a normal start. 2nd instance 2 weeks after 1st 04/04/2025 while stopped at a traffic light engine failed to auto start - same result as above (1st incident).

Dog walked on neutral button while truck was in motion, causing moving vehicle to unsafely go into neutral. Same thing can happen with a child or passenger who accidentally pushes the fully exposed button.

Engine "stop/start" turned off when trying to make a turn. When it did the steering would not move. Also when "stop/start" turns off it was dangerous when turning. I email Honda and they called me back. They could have it disabled but it would cost $80 and I would have to buy the part and they would install it. This is a new truck bought last month.

I was driving home climbing a hill in the slight rain when the check engine light came on. I drove with the light on to get to the next closest city about 2 minutes out from where the light came on. The engine was running rough and shaking the car and was having issues stopping at a light before I could pull into a parking lot. I pulled into the parking lot, my book said that it was a misfire and to let the engine cool off so I sat for about 2 hours, checked fluids then started the car. The ticking noise was there but there were no lights on my dash at the time and assumed it could make it home after I let it idle for 5 minutes. I proceeded to get on the road and the vehicle did ok. I got on the freeway to get home, slowly let the car climb to 50 and kept it there. 1 minute later the whole dash glowed saying everything was not working and giving special pop-ups on the dash explaining the vsa, abs, and electronic power steering were not working to name a few. I stopped the car and pulled over immediately and called for a tow. I took it to my local electric shop to see because the brakes still worked and they said that it was possibly the ecm, that they couldn't fix it, and the ticking was a heatshield, and to take it to the dealer. I then towed it to the dealer. The Honda techs said that they didn't know what was wrong because the car wasn't throwing any codes. They replaced the tailgate harness that the previous dealer I took it to didn't and said to replace the pully and tensioner before they drove and diagnosed it further. I had it towed to another shop to get those replaced. This shop listed some of the same fault codes as the first shop and when they tested the vehicle they had called me to come in and inspect the vehicle as they started it after it was at the dealer and told me it was an engine knock and that the engine would need to be replaced with the drive shaft. I called Honda's corporate office and they took my complaint and documented it only.

The automatic engine stop/start system is a safety hazard. On multiple occasions with two different drivers (husband and wife owners), the engine has stopped just as the accelerator is pressed after waiting for traffic to clear at a stop sign or while waiting to enter a street from a driveway or parking lot. The delay when expecting the vehicle to accelerate has nearly caused accident(s) several times. Drivers are forced to switch off the automatic stop/start system every time the vehicle is driven since it defaults to active and it is not safe to use. The system should be permanently disabled or at least programmed to be disabled as default when engine is started. This issue was reported to the local Honda dealer during the first routine service--owners were told that nothing could be done by the dealer. The service advisor suggested that we contact manufacturer or NHTSA directly. The incident date and mileage were entered below for yesterday since that was the latest event. It has happened numerous times since the vehicle was purchased in July 2024.

Sunday March 23, 2025 vehicle would not restart after the auto engine idle shut off feature turned off the engine. Attempted to restart several time with no success. Vehicle finally did restart when jumped the battery. Could be a safety hazard being stuck in traffic. Have not reported to dealer but will on next scheduled service. No warning lamps indicated a problem but every lamp on the dash console lit up when attempting to restart.

See attached document for complaint.

Unsafe auto high beams. They do not come on over 45mph. They have a mind of their own and seem to always come on and off at the wrong time. Also is dangerous to the oncoming vehicles that become impaired due to the high beams coming on when another vehicle is approaching. Especially most dangerous when you are on a 2 lane highway. Also the adaptive cruise control is inconsistent and seems to be very laggy and brakes way too hard.
