2024 KIA EV6

When I stopped the car in a parking lot, before I could engage the parking brake, the vehicle suddenly accelerated and climbed over the curb adjacent to the side walk. Stopped for few seconds and again suddently started accelerating. I could not stop the car as the brake appeared to be disenaged completely and was going all the way to the floor. The car went on the side walk, and descended on the road from the side walk and crossed the road, climbed on the curb again and stopped on the grassy area. Side airbag on the driver side inflated and the drive seatbelt tightened.

Brakes failed with unintened acceleration. We were stopped behind a truck at a stoplight when the the vehicle accelerated with a foot on the brake. We had it towed from the scene of the accident to our local dealership for testing. They had the vehicle for 4 weeks. Kia customer care was not responsive to our calls and emails or the dealerships. The dealership could not confirm the cause without their cooperation. The police were called to the scene of the accident and there is a report. The vehicle has been looked over by the service department at our local Kia lot. It was appraised for cost of damages by the collision center.

There is a safety issue with the specific implementation of the regenerative braking system when the car is put into reverse that I have experienced on several occasions. This is not a failure or malfunction of the system as it is working as intended nor are there any warning messages or alerts to signify a defect. The way Kia's system works is that regenerative braking is always on (like all EVs), but at a level you set from 1-4, with 4 being the most aggressive. I leave it on level 4(i-pedal) because I prefer one-pedal driving which I find to be more comfortable and safer. When the car is parked, or at a complete stop, if I put the car into reverse then the regenerative braking level is forced down to level 3. This creates a novel situation where regenerative braking is holding the parked car in place, but also the car won't move until the acceleration pedal is pressed. So I need to tap the accelerator then quickly move my foot to the brake pedal to stop the car which takes a couple of seconds. This causes the car to lurch backwards quickly until my foot reaches the brake pedal because Level 3 is not aggressive enough to bring the car to a complete stop in a short distance. Once I have held down the brakde pedal I can use that to slowly reverse more safely. I haven't hit anyone or anything yet, but I have had a few close calls from cars or pedestrians suddenly appearing from outside my view range at the same time I'm doing that initial reverse lurch. If someone were slower than me or have some physical hindrance that didn't allow them to move their foot quickly then it would be more likely the car may accidentally reverse into a person or car before the driver could respond. Being that regenerative braking is still engaged while reversing it should be a simple software change to allow for level 4 to be enabled thus eliminating the initial reverse lurch issue.

[XXX] about [XXX] our 2024 Kia EV6 WIND RWD AUTO VIN: [XXX] already serviced in both NHTSA Campaign #: 24V867000 and Campaign #: 24V200000 had a sudden loss of drive power and nearly all control while driving in rush hour traffic at 65MPH on [XXX] between Atwater and Livingston. The confirmed failed ICCU component can be inspected at Modesto Ca Kia. The sudden loss of drive power and control in rush hour highway traffic put me and numerus other rush hour highway drivers at catastrophic risk of multiple crashes, this could happen to anyone with the same car and especially concerning because our car had ALREADY been serviced in the 2 previous NHTSA recalls (see above) for the very issue (ICCU) that impacted our car nearly resulting in a catastrophic outcome. The confirmed failed ICCU component has only been inspected, and confirmed failed by the KIA EV certified technician at the Modesto Ca Kia dealership. Since owning the car [XXX] a yellow 12 volt battery lamp indicator, not a warning light, on the front dash would occasionally be lit randomly while driving or parked. Just moments before the sudden loss of power and control numerus warning lights and messages were appearing and the displays were flashing on and off. We had absolutely no: warning lamps, messages, symptoms, nor any other issue whatsoever with our car prior to this sudden failure while driving on the highway.
