2021 Honda Passport electrical problems

Filed Oct 9, 2026 · Electrical, Engine · TX

I was at a traffic light, when the light turned green I gave the car gas it hesitated, then went into neutral, the battery sign showed on the dash, the car would not go. I was 1 line under half a tank of gas, so I wasn’t empty. Also, just before this happened the radio became full of static on an FM channel. It wouldn’t allow me to switch to park to try and restart it. Scary and Frustrating!!!

multipurpose camera failure at 41000 miles. just past warranty

My 2021 Honda Passport experiences a sudden, complete failure of the digital instrument cluster and infotainment screen while driving. The dashboard controls go pitch black without warning, resulting in an immediate and dangerous loss of the speedometer, critical vehicle safety warnings, and the federally mandated rearview backup camera. The system stays dark for 3 to 4 minutes before attempting a forced system reboot. This matches the exact failure mode of the federal safety agency Recall 23V‑431 (MOST Bus Network Connectors). However, both the dealership and American Honda Corporate refuse to cover the repair, stating my specific VIN is excluded from the current recall footprint. This is a severe, active driving hazard that removes critical speed and safety information while traveling at highway speeds.

There is a known issue with auto idle feature. If you do not manually turn off every time it stays on and occasionally will cause car issue when stopping. I have had it happen in vehicle about a dozen times. When you fully depress brake engine is suppose to i gel to save gas however on occasion the vehicle will completely stall out. I have had this issue happen when approaching stop signs or in traffic situations. The biggest problem is trying to reengage car. Sometimes you can feel it starting to do this and if you quickly apply gas you can avoid it however sometimes the car will lock up with display lights and you have to keep pushing the Engine stop button to turn off the vehicle and turn vehicle back on. It is sometimes difficult to even turn off engine vehicle when this happens but seems to be only way to get vehicle to respond. I have had vehicles behind me almost hit me while I try to get vehicle out of this mode. I know it’s an issue as it’s all over the forums when you search for fix.

Honda has a recall on certain vin numbers for the starter. My starter i was told to replace at a $2500 fee from reggie jackson honda in raleigh nc. I had to visit the dealership 3 times, they said its the battery, replaced the battery at my cost, now they said its the starter. They said there is a recall but my vin number was not included in the recall. The starter is worn out from the auto start and stop feature at stop lights. My issue is it will stop at a stop light and it wont start again then a warning comes on the screen about collision detection issue, then the warning goes away quickly and eventually i will get it to start but it is a safety issue that honda is aware of. I am asking honda to do partial credit on repair costs, but i dont understand why my vin number was excluded. The managers name was ruben lopez who informed me that the starter is causing issues, and sometimes its the battery, but that my vin wasnt covered. I just want my vehicle to not get stuck at after stopping in traffic when honda knows of the issue it should be covered for a lifetime warranty or recall. The stopping issue where it wont start again happens approximately 1 time per month, and seems to be in warmer weather but i cannot confirm this nor do i keep an exact log of when it happens. Thank you.

4th occurrence. Car fails to start. The instrument display reads: AUTO ENGINE IDLE STOP SYSTEM PROBLEM. Electrical system including radio, A/C etc were working. (Including the car alarm which begins honking the horn as soon as I open the door) Repeated attempts to start the car failed to do anything except to annoy anyone within earshot as the horn kept honking! Roadside assistance was not able to get the car started either so it was towed to the dealer. I've had the car into the Honda dealer for recalls but this problem has not been solved.

After having constant issues with the idle stop and the car alarm going off in the middle of the night and day for no apparent reason I took it to the dealer to get it fixed. After supposedly fixing the idle stop, about two weeks later I was going up a ramp during a heavy traffic hour and the car completely shot down. It took me a few minutes to get it back on. I’ve had issues with this car from day one (brand new). I’m currently trying to get another car.

Vehicle has been having AIS issues for a couple of years, requiring new batteries, new starter/relays and countless internal computer updates (none of which have helped btw...). This morning she had the AIS engaged, went to turn left at a green light and when she released the brake the vehicle threw itself into Neutral and flashed a "Auto Idle Stop System Problem" message on the dash. She put it into park and tried to restart, which failed, she then had to turn the vehicle off completely and restart from there. As I mentioned, none of the computer updates Honda has done for this vehicle have helped and it's my understanding there is a block of vehicles in this age range (all Passports, Ridgelines and Pilots) that continue to have problems with the AIS as well. Honda needs to disable this "feature" on any vehicles they cannot fix via computer updates IMMEDIATELY before they get someone killed. Not to mention, we are sick and tired of having to replace the battery and/or starter every couple of years. Honda should not be putting tax breaks above their customers safety and satisfaction. You know it's bad when their 30+ year techs go out of their way to buy a used Honda just to avoid the AIS because they don't know what to do with it at this point either.

No incident has occurred. However, my concern is that a recall was issued on February 1, 2024 (the federal safety agency Recall Number 24V‑064), and as of October 31, 2025, Honda is still stating that parts are not available to complete the repair. I first contacted Honda in March 2025—over a year after the recall was issued—and was informed that the necessary parts were still unavailable. I called again in October 2025, and received the same response. We are now approaching two years since this recall was announced, and it is unacceptable and inexcusable that Honda has yet to provide the parts needed to correct this safety issue.

To preface: All of these issues only occur when the engine idle feature is on. I have not experienced any of these problems when the feature is off. Question #1: When I release the brake with the engine idle on, the vehicle will sometimes completely shut off. When this happens, the steering wheel and brakes lock up, and I am unable to restart the vehicle for at least 60 seconds. Question #2: On one occasion, my wife, our 8-month-old child, and I were stuck at a green light for about 60 seconds while unable to restart the vehicle. Cars were passing by at over 50 mph, and we were relying on other drivers to notice us in time. This situation has happened multiple times and poses a serious safety risk to both us and others on the road. Question #3: I have not taken the vehicle in for service because the issue is difficult to reproduce consistently. That uncertainty is part of the problem, along with the anxiety of not knowing whether the car will suddenly shut off. Question #4: For the same reason, I have not been able to demonstrate the problem on demand. However, the main concern is that I should not have to worry about my vehicle stalling when I go to accelerate. Question #5: The vehicle has completely shut off four separate times over the past year. On one occasion, after releasing the brake, the engine struggled to reach normal RPMs and the check engine light came on. I pulled over, turned the vehicle off, restarted it, and it seemed fine afterward, although it had noticeably less power while the check engine light was on. Lastly, there have been several instances where the engine did not completely shut off when the idle feature was on, but when I released the brake to accelerate, I heard a clicking sound and the vehicle seemed as though it was about to stall. It then resumed operation normally as the idle system re-engaged. Since this happens intermittently, it has been difficult to recreate during a diagnostic inspection.
