2022 Honda Pilot electrical system problems

“The contact owns a 2022 Honda Pilot. The contact stated that the rear passenger's side brake light was intermittently inoperable. The dealer was contacted and provided an estimate for the repair. In addition, the contact stated that several warning lights and messages, including "Air Bag Malfunction", "Adaptive Cruise Control Problem", "Collision Mitigation Braking System Problem", "Road Departure Mitigation Problem", and "Auto High Beam Problem", were displayed upon starting the vehicle and while driving, followed by a loud dinging sound. The dealer was contacted for a battery replacement estimate. The dealer provided an estimate but informed the contact that a diagnostic test was required prior to any repairs. The contact believed that deactivating the Auto START/STOP system might have caused the battery failure. The manufacturer was notified of the failure and informed the contact that the failure might be associated with the short lifespan of the battery. The failure mileage was approximately 101,000.”

“My 2022 Honda Pilot has experienced a serious safety malfunction involving its Idle Stop system. When the vehicle stopped and Idle Stop activated, the vehicle unexpectedly shifted into Neutral and would not allow me to shift back into Drive. I had to turn the vehicle completely off and restart it before I could drive again. This left the vehicle temporarily unable to move in traffic. Since XXX, the vehicle has required five replacement batteries, three installed by Honda dealerships and two elsewhere. In XXX, Honda sent us a letter titled "PGM-FI Idle Stop Software Update" and "Warranty Extension: Engine Does Not Auto Restart After Entering Auto Idle Stop." The notice referenced Honda Service Bulletins 23-008, 23-009, and 23-010. During our most recent visit to Honda of [XXX], the dealership diagnosed a failed battery and charged us $634 for replacement parts and labor. When we picked up the vehicle, we specifically asked whether Honda's PGM-FI software update had been performed. The service representative stated that the update was unnecessary because diagnostic testing did not identify the issue. We have not received confirmation that the software update was…”

“The car stopped in the middle of the high traffic highway in IL while driving to the airport on [XXX].The car failed to restart on few restart try. Vehicle was put on emergency flashing light and turned off / turned on. it would not start. The break / clause was stiff. We turned off the vehicle completely for few min and then restarted. The vehicle started. it was the scariest thing ever happened. as we were 5 member in the car and the situation was very risky, prone to accident and death.”

“Multiple dashboard warnings appeared simultaneously and deactivating Adaptive Cruise Control (ACC), Lane Keeping Assist (LKAS), Collision Mitigation Braking System, Road Departure Mitigation, Auto High Beam, Blind Spot Information, and Brake System warning. While on cruise control vehicle tends to slam brakes with no reason and nothing in front - major safety issue for driver.”

“The car has auto idle. It is the default and operates anytime the car is started unless you specifically push a button (each time) to turn if off. Starting about a year ago, the car battery seemed sluggish and then when I was driving if I stopped at a stoplight, the car would completely die and I had to restart it. Thinking it was a battery issue, I had a new battery put in on 10/15/25. But the issues have continued. Just recently, the car has twice died when I am at busy stoplights which could have easily led to me being rear ended. I have to put the car in park and attempt to restart it. It sometimes reads that the battery is dead, but then will start after a couple tries. I am taking it to my Honda dealer today, but they have already said "it's probably the battery - which is less than a year old and has a four year warranty.”

“Unknown. I took it to a local shop and they did read the codes but were unable to find camera or fix anything. I have 5 warnings that all came on one after one. Can not be cleared. We reset battery and a few simple fixes that didn’t work. Following warnings: Auto high beam problem, lane keeping assist problem, road departure mitigation system problem, adaptive cruise control problem, and collision mitigation system problem. I was driving on a smooth road with no issues and nothing happened, they just started going off one at a time. We have an appointment with Honda dealer on Tuesday September 29th 2026 to drop off to get checked out. I took it to my local shop on 9/24/26 with in an hour of it happening. Picked my car up from That shop on 9/25/26 they checked it out and said it was safe to drive but not something they could fix for me. I called Honda 9/25/26 that morning after picking up my car and they gave me the appointment.”
