“I have been taking my 21 Santa Fe hybrid limited into the dealership for a year and a half for the same code . Powertrain code P040B00, and to this day they can not repair this issue. I looked it up and a ton of us are having issues with this same code. It should be investigated, and customers should be warned. Hyundai needs to recall these vehicles or provide a solution. A year and a half is unacceptable”
NHTSA complaint #11533831, filed 2023-07“While I was traveling 70-75 mph the vehicle had a sudden loss of engine and battery output performance and I began losing speed. There was a very rapid decrease in speed, and no warning chime activated per manual. “Check Hybrid System. Stop Safely, triangle warning displayed.” The vehicle would not accelerate despite pressing the gas pedal all the way to the floor and had to be coasted off the interstate through three lanes of traffic to get to the shoulder. No fault indications were present in the Bluelink app despite warnings present on the dash. …”
NHTSA complaint #11477826, filed 2022-08“While driving on the highway, when I pushed on gas pedal the car would not accelerate, I was uncertain if I was losing power of the vehicle, luckily it maintained the current speed and did not decelerate,but I was unsure at the moment if I was losing complete power, because it wasn't responding, it felt like the car was going to stall similar to when you run out of fuel. This occured for around 20 seconds, i would guess, long enough to notice that the car was not responding and continued to not respond,and to be concerned from a safety perspective. …”

NHTSA complaint #11564397, filed 2024-01, 31,000 miles“Gas pedal stops working while driving down the road. Happened 3 times. Will work again after awhile. Dealership can't find what's wrong with it and so hyundai and the dealership said they can't fix it.”
