What 131 owners told NHTSA about the 2022 Kia Carnival

My 2022 Kia Carnival, approximately 80,000 miles, had intermittent dashboard warning lights and grinding brake noise for a few weeks. I brought the vehicle to Tasca Kia White Plains first time on 4/14/26 then again on 5/8/26. The dealership initially could not reproduce the issue, then later suspected an ABS sensor issue and ordered the part. On 5/12/26, before the repair was completed, I was driving downhill with my children in the vehicle when the brakes failed to respond properly. I had to steer off the roadway and go over rocks/boulders to stop the vehicle. At that time, the brakes would not respond normally, and I could not immediately shift the vehicle into Park. Police and towing services were involved. The dealership later replaced an ABS sensor. However, when I reviewed the codes with the service manager, I was told the ABS sensor code did not appear on the date of the brake incident. I was also told that an ABS sensor failure itself would not typically cause hydraulic brake failure. I am concerned that the sensor replacement does not explain the brake failure and that this may involve a brake/ABS/electronic stability control safety issue.

The back tailgate door, when opened, will go up to desired height set in car settings, then slam back down 1/4 to 1/2 of the total height. Turning off auto open and close it continues to do so. When manually pushing the door to the open position, it will continue the problem. We have had numerous incidents of heads being hit by the door, arms and hands have also been hit. We took the car to the dealership and they said the door actuator would be over $2000 to fix. It seems like this is a similar issue to the side door actuators that had to be replaced via recall.
