The contact owns a 2023 Hyundai Santa Fe. The contact stated that while driving and decelerating to approximately 10 MPH onto an exit ramp, the vehicle suddenly stalled and failed to restart. The contact noticed that there was blue smoke coming from the exhaust pipes, and several unknown warning lights and messages illuminated, including the Check Engine warning light. The vehicle was towed to the local dealer, who diagnosed that a fuel injector had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was not yet contacted. The failure mileage was 35,652.

Two unsafe scenarios in past two months: 1) Driving 80 mph, engine misfire, vehicle will not accelerate past 1 rpm, had to drive home from out of town with very slow acceleration, dangerous to not be able to accelerate efficiently on highways 2) Driving 55 mph, all driver safety systems malfunction, accelaration completely disabled, had to coast to safe stopping point. Restarted vehicle and could drive home with check engine light on, incredibly dangerous for car to lose all ability to accelerate in the middle of a highway.

I was driving down the road and came to a stop at a stop light. After accelerating again my car lost the ability to increase speed above 20 miles/hour and would not shift gears. I was heading to the turn lane to get on the interstate and quickly had to change lanes to find an area to pull over as I could not reach highway speeds. I turned the car off. I turned the car back on and the problem resolved. This is the second time this has happened. I have seen this problem mentioned dozens of time on Reddit message boards including Hyundai buybacks on some of these vehicles. It doesn't sound like Hyundai has any idea what is causing this issue. This issue should be looked into further.

Hyundai Corporate is refusing to ground or provide alternative transportation for a documented, warranty-covered engine cooling fault (Code P2181), creating a highway stalling risk. Hyundai's legal compliance team reviews these logs daily.

We were at full stop with Auto Hold feature enabled. Car lurched / jumped forward with no depression of the gas pedal. This caused us to strike the car in front of us.
