   Vehicle was involved in a double fatal. After viewing of dashcam video I suspect a malfunction of the vehicle may have occurred. The video appears to show the vehicle continuously accelerating despite the sound of what may be the driver attempting to repeatedly mash on the brakes. EDR records do not coincide with the dashcam video.

   The vehicle repeatedly displays a "Stop Vehicle and Check Brake System" warning together with an ABS warning, accompanied by a loss of normal braking response. On XXX, while driving at approximately 60 mph on I-85 northbound near Exit XXX in [XXX], the warnings appeared and the brakes did not respond normally. I was maintaining a substantial following distance, and the braking system restored itself before I reached the point of needing to brake hard, so no crash or injury…

   OnXXX, as we approached what I call the 6 o’clock position of a round-about in [XXX], we had braked almost to a full stop (0-5 mph) to wait on the car ahead of us to enter the round-about when we felt increasing movement. Despite braking, to wait on that car, our car with increasing speed started shoving that car into the circle. Fortunately, he was able to drive away from us, but that car had been damaged on the back and right side. With that obstacle out of the way, our…

   On [XXX], I received a warning on my 2023 IONIQ 5 that said “stop vehicle and check braking system” and the car went into “turtle mode”. I took it into the dealer for repairs and they said the issue was related to the 12V battery and returned the car to me as repaired. Then, on [XXX], I was driving the car and I got the same error message but this time the car’s brakes didn’t work. Thankfully, I was able to pull off the surface road I was on and pulled into a residential…

   When parking in a supermarket parking lot I slowly approached the space while braking. As I turned left into the space and released the brake pedal to allow the car to slowly roll into the space as I always do, the car surged as if someone floored the accelerator. I veered left to avoid a head on collision with the parked car facing me and went diagonally between the right front fender of that car and the left front fender of the car parked in the space to my left. I…

   I bought my Ioniq 5 in April 2023, starting in June 2023 I started having issues with the internal navigation system locating my vehicle on a different route than I was actually on. When I connect to Apple CarPlay to be able to use Google Maps or Waze, it also throws my cell phone system off and will be taken into wrong streets. Vehicle navigation also detected me driving in the wrong direction alerting me not to enter the street. I took video and photos to the dealer…
