   I was coasting into a library parking space with my foot off the accelerator. The car accelerated even with my foot on the brake, jumped a curb and was stopped with above ground tree roots. The dashboard should have been lighted up with collision warning indicators and the automatic braking should have engaged. It did none of that. The car was totaled. Nothing was ever checked to see if it was a mechanical error. My insurer totaled the car.

   While driving on the highway in foggy conditions, the smart cruise control system and forward safety system suddenly shut off while I was going 70 miles an hour. This almost resulted in a car rear ending me due to the sudden deceleration. The following day, with clear weather, the same issue happened again despite nothing appearing to have caused this issue while I was driving. This is a very serious concern to suddenly stop on a highway.

   ICCU stopped charging my auxiliary battery (Hyundai Ioniq 5). I couldn’t figure out why, but I began carrying a portable charger with me which instantly got my car going again. One day during a particularly nasty snow storm, my battery was dead again and I jump started my car. I drove it about 40 feet before I realized it needed snow socks. I stepped out of my car and got back in and a whole myriad of warnings were going on. I got a code for the vent flaps (snow had got…

    The cruise will shut off randomly saying the radar is blocked. When it does this the car decelerates very fast. Which is very dangerous in traffic. I’ve almost been rear ended a few times. It has also just started decelerating very fast when in cruise on highway for no apparent reason with no one in front of me.
