This is the 3rd time it happened to me. I was driving on the highway at speed 60-70 and a flash came across my dash that said emergency brake warning and my car started slowing down. I panicked and pulled over the road. The warning came on so fast and not even a min it stood on. It went off within 5 seconds. This is a safety hazard and can cause death when this happens. Please issue a recall for this to be fixed because this is dangerous to me and other drivers. I want my money back because this is the manufacturer defect or issue. They need to correct this before fatalities happen.

Had been traveling for approximately 2.5 hours in a winter storm, pushed on brake to slow down and park and the car started to chug. Turned car off and then back on again. Car would not start and had to be towed to nearest Hyundai dealership. There were no warning signs at all, car just suddenly quit. We were later informed that it was the fuel injectors. We were very fortunate that this did not occur in a place with no cell service on a very frigid, stormy night.

Driving going 30 mph, vehicle stopped accelerating. Error code was Engine Control System failure. Codes P2178, P0301 and P0087F0 were shown at dealership. Car was taken to dealership for repairs where the fuel injector on cylinder #1. 16 days after receiving car back, we went to start the car and it wouldn't start. After several attempts, gasoline began spewing from the car leaking an entire tank of gas on our garage floor and driveway. Very dangerous! Being towed to dealership again today.

I was traveling on the freeway when I began experiencing erratic acceleration, around which time the check engine light came on. I took the next exit, and continued to experience the same symptoms, as well as rough idling, and a bit of smoke. The car was towed to the nearest Hyundai dealership where the fuel injector was replaced under warranty.

Took a trip to the grocery store, and started up my car when I got back. The engine turned over but after a few seconds, it stalled. Tried this again, but lightly pressed the accelerator. This raised the RPM, but it dropped quickly and stalled the engine again. Made a couple more attempts after and eventually, the engine light came on. Shortly before this incident, I had about 10-15% of gas left in my tank. After this happened, bluelink reported that I had 1% left. Got the vehicle towed to the dealership, where they confirmed the condition and found that the fuel injector for cylinder 3 needed to be replaced. I consider myself lucky that this happened while my vehicle was parked. This would've been a huge safety concern if it happened out on the road.

The contact owns a 2023 Hyundai Sonata. The contact stated that on two separate occasions while driving at various speeds, the vehicle started to shake, and the vehicle lost motive power. The vehicle was pulled over to the side of the roadway and turned off. The vehicle failed to restart on both occasions. The vehicle was towed to a dealer where it was diagnosed that the fuel injector needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 11,000.

Forward Collision Warning appeared, vehicle lost power and would not accelerate. Vehicle kept loosing power. Multiple codes appeared. I am an ASE certified mechanic, so I went to my own business to get my scanner and there was a list of codes. Vehicle is currently at dealership and they are tracking down issues. Currently blaming an ECM but unsure. This is the second vehicle I have had this exact issue with. I have video that it won't allow me to upload of all the codes. I have a video of a previous issue, with a different vehicle. It's a 2023 Hyundai Santa Fe
