2023 Hyundai Palisade: sudden loss of power

Filed Jan 23, 2026 · Brakes, Electrical · IL

I am reporting a recurring, life-threatening electronic failure in my 2023 Hyundai Palisade. On [XXX], while turning into an intersection, the vehicle's brakes spontaneously engaged, stalling the car in the path of oncoming traffic. During this event, multiple critical safety systems failed simultaneously, including the headlights and horn, leaving me unable to warn other drivers. A "violent" surge was required to clear the intersection, risking a high-speed collision. Similar spontaneous recurrences occurred on [XXX] and [XXX], and most recently on [XXX]. These incidents are characterized by "phantom braking," total loss of propulsion, and a complete lack of interior/exterior electronic response. Technical Evidence: Diagnostic scans revealed 16 distinct fault codes (including C161608, C181287, and U012687) involving the Chassis Control Module, Electronic Control Unit (ECU), and communication buses. Despite these logged codes, Hyundai and the dealership have repeatedly returned the vehicle to me, stating they "cannot replicate" the issue, thereby dismissing a documented electronic record of failure. Arbitration Status: I entered into BBB Auto Line Arbitration (Case #[XXX]). Hyundai has contested the claim by attempting to manipulate the "start date" of the defect to February 2024 to avoid Lemon Law statutes, despite dealer records confirming the first occurrence in August 2023. As of January 13, 2026, the dealership is again attempting to force me to take delivery of the unrepaired vehicle. This vehicle is a "phantom" safety hazard. The manufacturer’s inability to replicate a logged electronic fault during a brief test drive does not mitigate the extreme risk of sudden braking and power loss at highway speeds. I am requesting a formal investigation into these specific fault codes and the electronic integrity of this model.

This incident occured on 4-2-2024, while driving to the doctor with my newborn daughter. Our 2023 Hyundai Palisade Limited did not respond/accelerate/move when pressing on the gas pedal. The engine/transmission seemed to malfunction when trying to pull off from a green traffic light. There was loss of power and the palisade would not move. This vehicle was purchased brand new and it is a serious safety concern that the vehicle can malfunction when attempting to accelerate.

When put in snow mode, there is a loss of power or failure for the car to accelerate at all. You can put the accelerator to the floor, and the car will not move forward. You basically can not drive in traffic. I had to pull over multiple times to the shoulder, because the car would not accelerate at all. I could not even get to the shoulder, because the car would not drive. Almost caused multiple accidents as the car stops without warning. It happens without any warning lamps, messages or other symptoms. It is not because the car is in snow and trying to not spin tires or get stuck. You can try to very gently accelerate and it still won't go. You can push harder on the gas, still won't go. It is like it stalls but the car is still running. Just all of a sudden will not accelerate. I took a video of it occuring and gave that to the dealership. I took the car to the dealership as it was new, and they could not "replicate the problem." We no longer used the snow mode after that incident. Now, approximately a year later, we had a winter storm, so attempted to use the snow mode and it happened again this week. Attempting to turn into oncoming traffic and the car stalled out, almost causing a collision. I have read online this is happening to multiple people and other people have contacted the federal safety agency. The dealerships can't "replicate" the issue, so no one is getting help. This is a serious safety issue that will cause a collision or worse, if it has not already. A recall and safety update to the system is needed for cars experiencing this failure!

When using the steering wheel paddles to manually shift gears while driving roads in hills, the vehicle will lose power and slow down. Have to pull over and shut off engine. On engine restart, engine power is back and problem is resolved.

First issue was engine misfire and loss of power while on the highway in the middle of no where. Car eventually died and was restarted. It happened twice at around 1700 miles on the odometer. Second issue is when the rear panoramic sunroof spontaneously exploded. I’m very thankful my daughter was not in the rear seat, as this happened while driving normal speeds. Sounded like gun shot. The sunroof spontaneously combusting seems to be a problem dating back to 2018 according to other reports online. Mine is a 2023.

I was just turning right from a stoplight into a store parking lot when I lost power steering & my brakes were ‘difficult’ to push down. I barely got it out of the way of traffic and I turned the car off, got out, opened and closed my door, and got back in and it started back up and drove to the parking spot like nothing had happened. Sensors reset to 0. It happened again 2 stops away while in a drive through. I did the same thing and it started back up ok. It would do this every 2-3 days for 2 weeks. Finally it did it one day, 5-6 times. The day I called the dealership & said that I was afraid my 2023 Palisade was going to literally get me killed on the highway was when the manager was able to get me a loaner vehicle to drive. It’s been in the dealership for over a week. I saw the recall about the loss of power brake assist online and thought this may pertain to my Palisade.
