2023 Hyundai Santa FE Hybrid Vehicle speed control Problems

“As I was driving today my Santa Fe Hybrid lost all power while on the road. The hybrid battery gauge went from 3/4th full to empty in 20 second and I could not get the vehicle to move. Thankfully there was no one behind me and I could safely pull off. When I stopped and restarted the car, the system said ready to drive but the car wouldn't move”

“On highway, emergency braking enacted. I pulled to side the of the road to turn engine off and restart car. When I did, I could not put the car in gear. I have had other similar incidents happen with this vehicle. After about an hour of waiting for roadside assistance and having NYS troopers come help, the car dash lit up and I was then able to put car in Drive. When I talked to dealership and said that I got a diagnostic message on my screen to have transmission component checked TODAY ('today' was in all CAPS on the screen), they said they could not get me in. …”

“The engine/ability to accelerate seemed to fail. It would not accelerate past 45mph and then couldn't even maintain that speed, even with the pedal to the floor. The engine sounded like it was revving at high RPMs and wasn't shifting into gear, even though it had just been in drive and operating normally. Yes, it is available for inspection. My safety was put at risk by not being able to accelerate when merging onto the highway, leading me to be going much slower than the traffic around me. I have not asked the dealer to reproduce the problem. The component has not been inspected. …”

“Bought the car in July 2023. Nov 23: I had a check hybrid system followed by check engine + red battery warning while driving in the interstate. The car lost power abruptly. Coasted out of the interstate, took the exit, and turned it off. Restarted after 15 mins. Only the check engine light came back on. We drove it back home. Just as we were entering the garage, the sequence happened again: Check Hybrid System warning followed by Red battery warning followed by car losing power. We had to push it back into the garage. Started it two days later and the check engine light was on. …”

“vehicle fails to accelerate, engine is “sputtering” and making a rattling sound and battery is draining to nothing on the freeway driving at normal speeds. vehicle is lurching and engine does not appear to be shifting as it should - car losing power and failing to accelerate despite being full of gas. transmission doesn’t feel like it is shifting properly. vehicle only has 8000 miles.”
