2020 Honda Ridgeline electrical complaints
Page 2 of 3: complaints 11 to 40 of 50, newest first, as owners wrote them.
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.
On two occasions the vehicles auto start/stop system has shut off the truck and not restarted it after releasing of the brake.
Stopping behind another vehicle. My vehicle engine was off because it was in ASD((automatic shutdown mode).Vehicle ahead moves forward. Immediately the dashboard says vehicle ahead has moved. Depressing the gas pedal the vehicle will not move forward. It does not come out of ASD. Message on dash says SHIFT TO PARK. Then I have to restart my vehicle The delay of moving is a safety hazard to me and obviously an irritant to the traffic behind me at least. Perhaps more than that. This has happened more than a few tmes
Scheduled my vehicle for recall related to the tailgate/camera/rear area warning system harness replacement for today 10-15-2024 after two notices. Upon arriving for my appointment, I learned that the dealer, Voyles Honda Marietta, GA does not have the parts, nor can they provide a time/date when parts would be available. Further, the Service Manager, Marvin, said the same parts issue is present with a fuel pump and electric steering campaign currently released. From prior involvement with many heavy truck campaign recalls, I know the O.E.M. Is required to have adequate repair parts to satisfy the released safety recall. In the previously noted Honda recalls this requirement is ignored by the manufacturer placing safety concern on the public, stressing dealers, and forcing vehicle owners to operate defective vehicles because parts to repair are not available, nor is there an expected date when they will be. Responses like “on manufacturer back order “ is not acceptable for a released National Safety Recall. Honda Corporate needs to be held accountable and owners need to be compensated for their inconvenience. Maybe restrict Honda from selling more vehicles until ALL safety campaigns are completed. the federal safety agency, check your records on Honda’s completion performance and take appropriate actions.
I experienced multiple warning lights on my dash when disengaging my cruise control on the freeway to pass a slower vehicle in front of me. Attached photo depicts these lights and a loss of dash gauges. I arranged a vehicle inspection from the purchasing dealer the next day, but later the entire dash “blacked out” losing speedometer, tachometer, turn signals, back-up camera etc. Given the uncertainty of the safe driving condition of the vehicle I opted to have a closer authorized dealer inspect the vehicle. The consensus was that there was a failure of the dash panel resulting in a $1600.00 repair. Learning that this exact failure was known to American Honda Motor Co., Inc. I reached out to their customer service since like year(s) models of the Passport, Pilot & Odyssey were part of an official warranty recall (along with extended warranty coverage) by American Honda Motor Co., Inc. to see if any goodwill assistance would be provided, given what I’m sure are shared components between the three models. Honda declined. In all transparency, I am a retired AHM employee who services my own vehicles, so their decline, I’m told was partially based on the lack of an official service history. The failure that I have described is totally unrelated to scheduled service. In closing, I am attaching a “screenshot” for a Honda Pilot Owners blog which goes into greater detail of the exact failure I experienced, described as inappropriate software programming. Again, these items in the Recall cited FMV SS101 & FMV SS111 as being key reasons for the issuance of the recall. Why the 2020 Honda Ridgeline which experienced this exact failure was excluded is a question that Honda should answer. Thank you.
When operating the vehicle in reverse, the dashboard screen was black/blank instead of displaying the view from the rear backup camera. The issue began to occur intermittently at ~40,000 miles and the camera was completely non-operational at 42,163k miles (10/21/2023). Upon investigating and diagnosing the root cause of failure, the dealer determined that the rear backup camera wiring harness failed. The failure point was a flexible section at the rear tailgate hinge that permits opening and closing the rear tailgate. Because the dealer's total replacement cost was too expensive (>$500), the original wiring harness was repaired by the owner. At 50,185 miles, the failure is intermittently occurring again with the repaired harness. A non-operational backup camera puts pedestrians, cyclists and others at risk when the vehicle is backing up because the driver may not be aware of their presence and could strike them or cause a collision. The local dealer diagnosed the issue and subsequently sold the owner a new replacement wiring harness that has yet to be installed. The vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others. No warning lamps, messages or other symptoms of the problem occurred prior to the failure.
Back up camera no longer works, all black when in reverse.
Back-up camera failed.
Rear camera does not work. After investigation found four or five broken wires in the wire harness that goes to the rear camera and some other stuff
The back-up video is not operating on this vehicle. It stopped functioning properly within the past week. In checking on this, it appears multiple other owners of this vehicle are experiencing the same issue and it generally relates to wires being pinched or cut accidently due to apparent design or equipment failure while vehicle is being operated in routine fashion. Specifically, it appears these wires are pinched and ultimately severed when tailgate is being opened/closed. This is an issue as the camera is very important manner for safely backing.
Rear Camera has stopped working. Black Screen. Poor rear visibility when trying to back up causing a safety issue. Same Issue as Service Bulletin 22-049 describes, except this is a 2020 not a 2019.
My rear back-up camera suddenly stopped working. The display screen is fine, but no signal is reaching it. No warnings or messages. Worked one minute, not the next. Looking on-line in the forum, it looks like a common failure of the wiring harness at the tailgate.
Backup camera wires pinched, camera stops working!
The backup camera suddenly went black. I saw this was a problem that led to a recall on earlier models of the Honda Ridgeline. I was fortunate in that the dealer did get it covered by the warranty department. The confirmed it was a wiring problem.
Back camera failed and screen goes black.
rear view camera and rear traffic and warning systems stopped working. Honda diagnosed and repaired the wiring harness. the federal safety agency has opened an investigation PE24004 which appears to identical to the issue we have.
Rear back up camera stopped working. When putting the truck in reverse the video display only shows the yellow grid lines. The camera video is black. I saw on line that this is caused by a faulty wire harness. There’s a you tube video showing where the problem is and how to fix it so this must be a common issue. I followed the instructions from YouTube and I took the tailgate apart and found that the camera wire was broken. I spliced the wire back together and now it works again.
My rear camera stopped working. My understanding is that it is a defect in the wiring harness. My rear camera is not useable, and makes backing up very difficult and is a potential hazard.
My cars auto engine idle is malfunctioning causing my car to have serious transmission issues. I currently have 3 warning signs on my dashboard. 1. All wheel drive system problem 2. Auto engine idle stop system problem 3. charging system problem. I bought the car used last year. Its a 2020 honda ridgeline with only 29k mikes. Ive been seeing reports online that this issus has been affecting many honda users. Please help!! Honda needs to be responsible for this problem! RECALL NOW!
My reverse camera was intermittent approximately 2 months ago. It would occasionally flicker, but then went totally dark with no picture. I took it upon myself to investigate for a loose wire as I know this was an items that was recalled on the 2017-19 models as well. I did find a severed wire, which leads me to believe that the same issues that forced a recall on the previous models is also affecting my 2020 Ridgeline. The absence of the backup camera makes backing out of parking space or the potential for colliding with other cars or pedestrians a very real concern.
Rear view camera wiring harness broken. Recalls on 2017 to 2019. My truck is built in 1-20 and is out of warranty. Same issue as with previous Ridgeline harness. Safety issues with no backup. Dealer refuses to do anything about it as it is not in current recall and it's out of warranty.
Back up camera is black with yellow lines
I shifted the vehicle into reverse and the parking assist camera (backup camera) did not appear on the infotainment screen as it should. There is an active recall on the 2017 - 2019 models as Honda is aware of this problem with the tailgate wiring harness design. Backing up without the visual aid poses a serious safety threat to any pedestrians or vehicles that may not be seen due to the camera not working as it should. I have not yet scheduled a repair for this item but will update when the problem is remedied. There was no warning before this occured. It was sudden without any signs. It is my hope and the duty of the manufacturer that this issue is fixed within ALL model years that this problem is known to occur.
The contact owns a 2020 Honda Ridgeline. The contact stated while stopped, the automatic STOP/START feature intermittently failed to operate as needed after the vehicle had shut off. The contact stated that the vehicle would independently shift to neutral(N) during the failure. The contact called the dealer and was asked to bring the vehicle in for a diagnostic test. The manufacturer was also notified of the failure and referred the contact back to the dealer for assistance. The vehicle was not repaired. The failure mileage was approximately 18,000. The VIN was not available.
Rear camera has failed and no longer works. Previously flickering then went dead. Same problem as with 2019 Ridgelines and other Hondas. Has been extended to other 2020 Hondas but not the ridgeline. This is an early build ridgeline that was delivered in Jan 2020.
The backup camera stopped working. The wires to the camera broke. This is the same issue as the 2017 - 2019 Ridgeline recall. When will the 2020 models be recalled?
The wiring harness for the rear back up camera is beginning to fail. I know this is an issue and has been a recall on the 2017-2019 model years. The harness that fails is the exact same on the 2020 model and should be recalled as well.
AT odometer reading 35870, while loading the pickup for a trip home the backup camera failed. No local dealership was open on the weekend and we were 600 miles from home. Upon arrival, Monday, the local dealership was called and we were told the repair would not be covered by warranty and a similar recall on 2019 vehicles would not apply to 2020 model year for the same issue.
Rear view camera ceased to display picture. Screen black except for yellow guidelines and view options. inspection of rear tailgate wiring found 3-4 wires in wiring harness corroded/broken. This is similar to known issue with 17-19 ridglines which have a TBS out for same issue.
