My 2022 Kia EV6 developed a serious electrical/MCU malfunction on 10/19/2025 at approximately 64,300 miles. While driving, the vehicle began to stutter during acceleration, all driver-assistance and safety systems disabled (LKAS, collision avoidance, lane keeping), and the vehicle could not accelerate normally (topping out around ~60 mph when fully pressing the pedal). The Kia Connect app displayed fault codes MCU P0A4100 and LKAS C164286. The malfunction recurred immediately after a dealer visit on 10/20/2025. The vehicle has since been inspected by Huffines Kia in Corinth, Texas, but no confirmed diagnosis has been provided, nor have they notified me of dropping/reconnecting the HV battery. On 11/18/2025, a new fault code appeared: MCU P0C1700. This failure affects the high-voltage electronics/MCU and causes sudden loss of acceleration capability and complete disabling of active safety systems while the vehicle is in motion, placing me and other drivers at risk. The issue is reproducible, continues to occur, and the vehicle remains at the dealership. I am requesting the federal safety agency review of this electrical/MCU malfunction as a safety-related defect.

After driving the car for a while, when the car is parked and the car is still ON, the car began displaying - Check Lane Assist warning. From that point, the Smart cruise is not working. The warning displayed for more than 20 days. It happened to me more than 5 times. I reached out to Kia and their engineer is unable to resolve it. The warnings get erased after 20+ days. In the recent visit, Kia engineer asked me to change all 4 tires, which I did along with the Wheel balancing and alignment, still I got the same issue last week.

While driving at normal road speeds, the vehicle suddenly lost all electronics (infotainment, air conditioning, dash). After 2-3 minutes these systems came back online but the car continued to have a warning light for the Lane Keeping system not functioning. This warning now comes on periodically after this incident

The contact owns a 2022 Kia EV6. The contact stated that the stereo system started making abnormal noises then went black. During the failure, the Lane Departure Assist, Parking Assist, and other unknown functions became inoperable. The dealer was contacted and stated that the amplifier needed to be replaced. The vehicle had not been repaired due to the parts not being available for the repair. The manufacturer was made aware of the failure and filed a warranty claim. The approximate failure mileage was16,030.

I was driving on the freeway with the lane keep assist and adaptive cruise control engaged.the system worked fine for a while but when I took my eyes off the road for a quick minute to grab something from the back seat, the system either disengaged without a waraning or decided to steer to the left outof the lane, because in that short time, it moved two lanes to the left and hit the road barrier deploying the airbags and causing injuries to the passengers. The vehicle was declared a total loss. There were no warningss before or during the incident to indicate any kind of issue. I believe the hda software on the ev6 is quite buggy as a similar incident happened a few months prior when the car randomly decided to take an evasive action to the right when there was no one else on the road. In that instance I was holding the steering wheel with my eyes on the road so I was able to apply immediate corrective action to prevent a mishap

This vehicle is equipped with Semi Autonomous Driving. While using Semi Autonomous Driving with Navigation and all other Safety Items active, the vehicle swerved out of its lane and side swiped a Semi before driver could react and move vehicle back into lane. Multiple items failed. Semi Autonomous Driving - Lane Assist - Lane Keep - Emergency Breaking - Blind Spot Warning. No warning lights / sounds activated. (We have a video of this happening a 2nd time but we avoided the accident). Damages to car is roughly $14k and luckily it was not worse as loss of life could have happened. KIA has been notified and the claim is 14832390. Current status is they want the dealership to review the vehicle once the Body Work has been fixed. KIA wants to see if they can recreate the incident. Vehicle is still being fixed and expected to be available to me on 8/26/2022. Afterwards, I will provide the vehicle to the Dealership. (Hoping they will not perform updates to fix the problem and inform me they could not reproduce the issue) FYI - I am not able to download the video to this complaint. Your system will not allow my video format. Also, for final damages, the price is higher than attached documents as Collision Center has added to the claim.
