2021 Honda Passport Other or unknown Problems

“The emergency collision system constantly actives when there is no need for it to activate. It’s more of a safety hazard. I have just under 40 years of driving experience, former mechanic, and police officer for over 20 years. My professional opinion is, Honda needs to correct this problem. Thanks.”

“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.

This happened multiple times without receiving any warning or notifications, just suddenly. It would happen without warning, or sometimes nearing a bridge or a cover plate on the road, which almost caused accidents multiple times to get rear ended. …”

“I purchased my vehicle in August 2023 (used). Phone calls (both through using CarPlay and with the phone unplugged and with genuine cables) sound terrible on the part of the recipient. We replaced the FAKRA cables and harness late last year and just replaced the microphone (and I got charged a diagnosis fee). The issue is continuing. It's gotten so bad that I have to use my AirPods to make any calls for my recipient to hear anything I'm saying (which is illegal in my state and should not be a requirement in a car that is less than 3 years old). …”
