2024 Hyundai Santa FE Hybrid Transmission and drivetrain Problems

“We had notice that my wife's 2024 Santa Fe Hybrid Calligraphy AWD, is shuddering and vibrating at low speeds 20 to 40 mph always. Probably now is a little more accentuated. There is nothing on the steering wheel, but in the whole vehicle. Because this is not new, and I am not always driving this vehicle, I need your assistance as soon as possible.”

“When accelerating from a stop, the transmission fails to engage causing the engine to rev but not allow for movement until the gas pedal is disengaged then engaged again. This happens sporadically and I have not been able to find a pattern or reason for this issue. I have reported this to Hyundai and taken the vehicle in but the dealership was unable to reproduce the issue after driving the vehicle for 20 miles. This is a safety issue as the vehicle does not always accelerate as expected from a stop and could potentially cause an accident.”

“While driving on the highway the vehicle lost power and then lowered the transmission gear and would not accelerate over 17mph regardless of pressure on accelerator. I switched from auto hybrid mode over to sport mode so the gasoline engine could be used yet the transmission would not increase power to the tires. I stopped several times and restarted with no corrections. Vehicle battery drained quickly and vehicle alarm told me to pull over to charge battery. Sat for a few minutes to charge battery, put in drive and vehicle went forward to 17-20 mph and would not go any faster. …”

“We purchased our '24 Santa Fe hybrid on 9/18/24 new with no problems. On 10/8/24, about three weeks later, I was stopped at a stoplight after exiting the freeway. When the light turned green, I accelerated and felt a clunk, then the car would not accelerate past about 30 mph. Several warning lights came up on the dash. I could hear the engine revving, but it felt like it wouldn't go into the next gear. I thought I could make it to the dealership, which was only a few miles away. But at the next stoplight, I was stopped in a turn lane, and when I pushed on the gas nothing happened. …”

“The vehicle will not accelerate past 30 mph on the highway. The fuel system will not engage, and the vehicle continues to run on hybrid mode which causes the battery to drain and acceleration to throttle. This occurs on all drive modes and fuel conditions.”
