2021 Honda Pilot Electrical System

I was driving my Pilot and came to a stop during stop and go traffic on a highway. Normally the auto stop/start feature would stop the engine and start it again when I released the brake, but at this stop the vehicle stopped the engine and lost all power. The car went completely dead. As traffic started moving again I had no idea what was going on and my vehicle was in the path of moving traffic causing a hazard and safety risk to myself and others. I was able to restart the vehicle with the normal procedure, but it was in park and had to be shifted back into drive to get moving again. This became a normal occurrence so I took the vehicle to Honda for evaluation. They contend that the battery, while still "good", was not providing adequate voltage for the stop/start system. Proposed solutions were continue use but manually deselect auto start/stop function each time I started the car or replace the battery (at my expense - not covered by warranty). I am reporting this due to how the vehicle handles this lower voltage state of the battery. I think it if the vehicle senses this situation it should 1) notify the driver of the low voltage state of the battery and 2) automatically turn of the auto start/stop function of the vehicle thereby preventing an unsafe and startling vehicle shutdown while on the road and in traffic. This is an unsafe vehicle reaction that should not occur with proper system programming. I confirmed with the dealership this is a normal occurrence when the battery falls below certain voltage requirements, but the operator of the vehicle has no prior knowledge when this situation might occur (ie no warning light). This creates a potential for vehicle accidents and personal injury. Some type of warning and automatic suspension of the auto stop/start feature should occur.

There is speaker cracking noise and monitor goes black when using navigation. This is distracting and dangerous do to myself as a driver and others. It is distracting and concerning that a new vehicle goes crazy and Honda has no idea how to fix this. I have taken the vehicle to get serviced 4 times and still there is no resolution.

The contact owns a 2021 Honda Pilot. The contact stated that the information center was not connecting. There were no warning lights illuminated. The vehicle was taken to the local dealer for NHTSA Campaign Number: 20V439000 (Back Over Prevention, Electrical System) and the vehicle was repaired but the failure occurred. The manufacturer was not contacted. The failure mileage was unknown.

When the automatic engine shut-off is engaged during traffic stops, sometimes the power to the vehicle shuts off. It can happen at stop signs with out warning. The vehicle usually powers back up in Park.

There is an issue with the electrical system in this car. The radio has intermittent static on any station and hands free calls drop after a short period. I have Googled this and it is a very common complaint on this type/year vehicle. I am concerned there are other electrical issues that may be more safety related. The dealer did a hard reboot of the computer, but nothing changed.

I was about to cross the border I was not driving faster than 3 mph when a few functions stop working

The dash crackles sometimes a little and other times it crackles constantly all across the dash. If the radio is playing, it interferes with the radio or using the Bluetooth. At first it seemed like something hit the windshield and now it's worse and crackles all the time. There was a recall on this recently but not for the 2021 Pilot. This needs to be fixed. It is quite distracting and annoying.

The contact owns a 2021 Honda Pilot. The contact stated while driving 30 MPH, he noticed that several warning lights illuminated and remained illuminated. The contact continued driving to his residence. The following day the warning lights disappeared. Several months later the failure recurred. The contact took the vehicle to the local dealer to be diagnosed. The mechanic related the failure to an unknown electrical failure and performed a software update to fix the vehicle. the contact stated that the failure recurred. The vehicle was taken back to the dealer but was not diagnosed. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 1,000.
