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.

From what I have been told there is no recall on this issue. Purchased a Hyundai Sante Fe Hybrid 2021 brand new in 2021. I live in La Quinta California summers are especially hot. Temps can be anywhere from 105 to 120 . Only had the car for 6months when in light came on saying Inverter needs coolant this has been a problem for the past 2yrs. Checked with Hyundai Service department my coolant is fine air conditioning works well. This not a safety issue but should be fixed and Hyundai is doing nothing about it. Many complaints have been ignored.

Whenever the weather gets above 80 degrees outside my car put a notice to refill inverter coolant, when everything is filled max line. I’ve mentioned it twice to the Hyundai service and both times the employee told me not to worry about it and it is a sensor issue. That is unacceptable, I live in Las Vegas, Nevada where temperatures on average in summer are 90+. That’s a big risk an unnecessary danger to have my car engine over heat and stop in the middle of no where and potentially leave me stranded or worse cause an accident or fire. On top of that I have to see the message every day in the summer temperatures, without any way to remove the message. This will be the 2nd summer I’ve seen this message appear in my car, and I’m tired of the dealership & their car service staff telling me this is nothing to worry about… especially on car not even 4 years old!

On December 28, 2022, we were driving 70 miles per hour on Route 75 in the third lane of a four-lane highway from Michigan to Tennessee. In Ohio, the vehicle lost all drive power without warning. As it decelerated, we were able to maneuver the vehicle to the breakdown lane, narrowly avoiding other vehicles around us driving at 70 miles per hour. We do not know what caused this to happen. After several hours on the side of the highway, the vehicle was towed to Jeff Wyler Hyundai in Fairfield, Ohio. They have not been able to diagnose the problem as of today. The contact stated that the cause of the issue was due to an oil plug that was improperly tightened by the dealership during service maintenance. As a result of that, the oil was able to drain out and cause the engine to fail.
