“I have had 2 major issues, the idle stop feature has multiple times caused my car to stall. It has even happened on the highway during traffic where the car went into idle-stop mode and would not restart the engine. Last week it happened again on a major road and the only way to restart the car is shift to park in the middle of a busy 4 lane road, turn off the car completely and then attempt a restart. The other issue was with the rear sliding door, my 3 year old son closed the automatic sliding door by pressing the button and his hand was crushed/ stuck until I was able to reopen it. I have called Honda who told me I could have it looked at but it would cost me for the diagnostic and repair if needed due to the fact that it was one month past their 3 year warranty period.”

“Multiple sensors malfunctioned. Mechanic read code U3000-49 (Multipurpose camera unit/millimeter wave radar internal electronic failure). There was no collision or damage of any sort that led to this malfunction. The following systems no longer work: Adaptive Cruise control Collision mitigation system Lane keeping Assist Road departure mitigation system Blind spot info system Tire pressure monitor system Transmission system All of these failures started at exactly the same time. This severely compromises the ability to use this vehicle safely as these systems are all designed to prevent various safety hazards.”

“When vehicle is completely stopped at a traffic light there have been numerous occasions in which all electrical components fail and the vehicle turns off and fails to restart. This only occurs when the auto idle start is engaged. A few times I’ve had to completely jump the vehicle. I have replaced the battery and also had the car examined at the dealership. They stated they had previously updated the system, had heard of other instances of the same issue but since it wasn’t under recall and they couldn’t replicate the issue they couldn’t do anything. This has proved to be extremely dangerous because at rest, without being able to restart when the light turns green my family and I are at risk of being severely rear ended at high speeds.”
