“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”
“While driving 80 mph down the highway my brand new vehicle shut off completely, the entire car lost power. In another instance I was going around a roundabout and my acceleration completely went out, my son was in the back seat and another car had to jump the curb to avoid crashing into us. I met a woman in the dealership who has been waiting over a year for her recalled tow hitch to be fixed. When it rains or snows the forward safety systems shut off and the alert repeats extremely distracting on your dash, like sounds, red flashing lights, over and over again. You have to constantly hit the ok button while driving to get it to go away.”
