Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Auto Engine Idle shut off engages when the vehicle comes to a stop. Upon releasing my foot from the brake pedal, the truck shifts into park as the engine restarts. This happens about 75% of the time when engaged. If I turn this feature off, I experience no issue. This is a government mandated feature that appears to be a problem. I need support in making sure that Honda takes responsibility for this issue.”
