2017 Hyundai Tucson Fuel Cell electrical system problems

“The controls (buttons) on the right side of my steering wheel progressed from slow to respond to completely unresponsive, and then the driver airbag light started coming on. At first it was intermittent, then constant. I didn't expect those two issues to be related but did come to learn it was the clock switch. According to my Hyundai dealer, this is a known issue in several other years/models of Hyundais and they have extended those warranties, "but it hasn't reached the Tucson yet". I was told that either 1 - my airbag wouldn't deploy or 2 - it would deploy randomly when I was driving the vehicle. I spent nearly $1000 in diagnostics and repairs.”

“Power windows will go down by driver buttons but driver buttons will not work to make windows go back up. Engine is stalling, can smell exhaust, manifold is said to be needed to be replaced. Burns oil badly.”

“1. After driving the car and turning it off, I get a loud bang coming from a gas tank. 2. Sometimes when making a hard right or left turn steering wheel vibrates, and the warning light for all wheel drive system comes on. When I turn the car off and restart it, it goes away. 3. After software installs due to recalls, when I accelerate my radio occasionally shuts off on its own, and then we’ll come back on on its own. 4. After turning the car off when I restart it occasionally the clock in calendar revert to 00:00 for the time and the date resets to 1/1/20.”

“All of the lights on the dashboard and check engines light were illuminated. The speedometer would not work and the stick shift would stick in park causing me to have to release the shift lock manually to drive. The failure mileage was 59,450.”

“Rear driver side door suddenly will not open from outside or inside. A rear passenger would be essentially trapped in the car should an incident/accident happen. I googled and it seems this is a well known issue affecting several model years of Hyundai, including my 2017 model. I do not see a recall for this extremely dangerous issue.”

“I am writing to report a serious issue with our 2017 Hyundai Tucson. As the first and only owners of this vehicle, we have diligently maintained it through authorized dealerships. However, in May 2023, while driving on the highway, the car suddenly lost power and would not accelerate beyond 30 mph. There were no warning lights or indications prior to this incident. My wife managed to pull the car to the side of the road and slowly drove it to the dealership. Despite having only 30,000 miles on the odometer from personal use, we were shocked to learn that the engine had suffered significant damage due to low engine oil. Notably, we had recently serviced the vehicle at the same dealership just a few months earlier. The dealership informed us that the engine needed replacement, but the process took nearly a year. During this time, we were left without our vehicle, causing considerable inconvenience and financial hardship due to renting replacement vechile . We find it concerning that an engine failure occurred despite our regular maintenance and adherence to authorized service centers. We kindly request an investigation into this matter and hope that steps can be…”
