2019 Honda Pilot electrical problems

Filed Nov 4, 2026 · Electrical, Engine · NJ

Frequent struggles/failures to restart engine from the auto idle start/stop feature engaging. Multiple times, despite top of the line battery with AGM have even failed to restart the car and that is with a battery being than a year old. Wife and children have been stranded at a light in the middle lane of a busy roadway, intersection and at work. These issues also occur from cold starts, again, with newer batteries + AGM at just about the 1 year mark each year. Costs, risks, inconvenience that have been present year after year. We MUST disengage the auto idle feature manually every time we enter the car or else we are at risk for our safety or at the least a costly/frustrating series of events to restore the situation.

Auto Start / Stop for the engine when coming to a stop at idle. We cannot replicate the situation over and over, but it has happened numerous times. If the auto start stop feature is allowed to function and the vehicle motor turns off at a stop sign or a stop light, it sometimes does not turn back on when you let off the brake and push the accelerator. This puts us in a very dangerous situation at intersections with a stalled out car. It sometimes takes several minutes to restart the car, all the while (my wife usually drives this car) she is panicking while cars honk and swerve around her disabled car. Honda dealer has been less than helpful stating they cannot do anything unless they can replicate it in the shop. Most recent incident happened today while my wife was driving to work.

VEHICLE: 2019 Honda Pilot EX VIN: [XXX] CURRENT MILEAGE: 77,000 miles COMPLAINT DESCRIPTION: I am filing a critical safety complaint regarding a catastrophic transmission failure that actively disables my vehicle's advanced driver-assist and automated safety systems while driving, creating a severe crash hazard. At approximately 36,085 miles, the vehicle experienced a severe torque converter judder. The dealership performed an 11-quart transmission fluid service. Immediately following this service, the vehicle began suffering from unpredictable, cascading dashboard warning lights that completely disable the vehicle's automated safety braking, forward-facing camera suites, and vehicle stability systems. The dealership repeatedly misdiagnosed this powertrain fault as a camera/sensor issue, charging me out-of-pocket for a front multipurpose camera replacement that did not resolve the issue. At 77,000 miles, the transmission suffered a complete failure. A diagnostic tear-down confirmed a stuck solenoid valve and destructive metal shards circulating throughout the transmission and fluid lines. The primary safety hazard is that the mechanical failure of the powertrain and torque converter actively sends erratic data to the vehicle's central computer, instantly shutting down the automatic emergency braking system, lane-keep assist, and forward collision warnings while the vehicle is in motion on public roads. This forces the driver to operate without critical automated safety features unexpectedly. Honda has issued an extended warranty for transmission judder on certain 2019 Pilots ([XXX]), but claims my specific VIN is excluded despite experiencing the exact same catastrophic mechanical and electronic safety failure. I request an investigation into this safety-disabling defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Honda DTC U3000-49 Internal Electronic Failure of the Multipurpose Camera. Ran into an issue where most if not all system modules began flashing warnings in the instrument cluster. The last time this happened, we found our original factory Honda battery to have finally failed. We replaced the battery 6 months ago, thus it's basically new. Naturally we thought possibly that something happened to the battery again, so we brought it back to Goodyear, and they ran tests. Alternator charging system was good, and so was the battery. They reset the system, and all of the warning lights went away for about 5 minutes. After idling for about 5 minutes, all of the random warning lights came back on the instrument cluster. Since the system was reset, the only thing that was flagged after pulling the codes post-reset was U3000-49, which after some research appears to be somewhat common. I talked to my local Honda dealer and they said the cost to fix this is in the mid to high $2000 range. I had to pay Goodyear $67.98 due to the fault not being with their installed battery, and they let the car go saying they couldn't do anything, so I contacted Honda.

This vehicle is equipped with Honda's Auto Idle Stop (AIS) system, which shuts the engine off automatically when the vehicle comes to a stop and is designed to restart it when the brake pedal is released. On XXX, while stopped at a light at approximatly [XXX], the engine shut off as normal, but failed to restart when I released the brake. The vehicle was inoperable for approximately one to two minutes while stopped in a busy traffic muilti-lane road at a light over an expressway, creating a serious risk of being struck from behind by other traffic. This is not an isolated occurrence, I experience this AIS no-restart failure on a regular/recurring basis, not just this one time. I am aware that Honda has issued service bulletins related to this issue (TSB 23-008, TSB 23-009) and that this defect is the subject of a certified class action settlement (In re Honda Idle Stop Litigation, No XXX). I believe this represents an ongoing safety defect that creates a real risk of a collision, particularly in higher-speed or higher-traffic conditions where a temporarily immobile vehicle is a hazard to itself and surrounding traffic. This vehicle has a rebuilt/salvage title (repaired and retitled prior to my purchase; it passed state inspection and is legally registered and roadworthy). When I contacted Honda about repair under the applicable service bulletins (TSB 23-008 / TSB 23-009) for this defect, I was told the rebuilt title status disqualifies this vehicle from that repair coverage. I am not seeking a warranty or cost remedy through this complaint, I am reporting this because it means an unknown number of vehicles with this safety defect are currently excluded from any manufacturer-provided fix, leaving the underlying no-restart hazard unaddressed on the road.

When at a red light or stop sign the vehicle will idle and turn off. The vehicle doesn’t want to restart. It takes a bit to get started again then it progresses.While parked I turned the car off for 5 minutes and it would not start up again. Tried the jump cables to make sure it wasn’t the battery had to have a tow truck come they were able to get the car jumped and started. Took the battery to get tested and the battery was perfectly fine. Something is wrong with the starter. It doesn’t happen all the time but it has happened to me a few times and it’s not safe with me and kids in the car.
