2 unrepaired recalls. Frame rusted and unsafe to lift to repair the other recall which is an oil leak onto the alternator. Car won't run now. Corporate asked if I had a lawyer. They have declared my car not fixable or drivable. Neither corporate nor dealer will return my calls. No info from them at all. No offer of a buyback. No anything.

Vehicle will suddenly shutdown in the middle of the road. This could easily have caused a crash at any time. Several batteries have been replaced due to alternator not charging the battery. Then the battery has to be jumped for emergencies. I have taken the car in for repairs of the recall twice. I was told that the front end would come off and parts would have to be replaced because of the age of my vehicle they would not fit again. I need a solution to this problem.

I would like to point out we did not see any visible signs of the gasket was leaking. We had our regular scheduled oil change in Feb of 2025 and no report of an oil leak. We had a service event at the end of June 2025 and were told there was a visible leak was present and appeared to be about 3 months old. We took it back to the dealership and reported the recall issue was occurring. This was 7/25 and just outside of a year. The stated it would not be covered under warranty/recall now. I called and complain to Hyundia corporate. Waited 2 weeks to say it would be taken care of by the dealership. Called them today to arrange for bring the car in but they had no record of what I was told by Hyundia corporate. I believe this breaking faith w the whole recall process with the NTSB.

I am having a serious issue with my car that mechanics are unable to figure out. On multiple occasions, while driving at low speed in preparation for making a turn, my car has completely shut off, making it impossible for me to steer, brake or accelerate. I lost all control of my vehicle. I noticed the ‘check engine’ and ‘battery’ lights illuminated each time, but this information, along with incident descriptions, has proven less than helpful when I’ve taken it into a shop for inspection/repair as mechanics have been unable to reproduce the event or to accurately identify the problem. This has happened on the road (at intersections and once at a traffic circle) and on two occasions while I had a passenger in the vehicle with me. I currently have my vehicle back in an auto shop because it happened most recently about a week ago. However, since the problem has yet to be successfully identified and since I feel as though this is a serious safety issue that could impact others with the same type of vehicle, I am filing this official complaint.

Contact owned 2009 hyundai santa fe sport utility vehicle. At 2pm on july 7, 2017, driver experienced a sudden, uncommanded acceleration that caused a fatal crash that resulted in the death of the driver and two passengers. Manufacturer was informed about the subject incident. Hyundai is aware of a statistically significant number of unintended accelerations with this generation of vehicles. Other public voqs and private consumer complaints support the contacts allegations that the vehicle had a catastrophic failure with the electronic throttle control system. The 2009 hyundai santa fe was not equipped with available 'smart pedal' brake throttle override technology. In 2012, hyundai admitted that "with virtually all cars using electronic throttle control today, there remains the remote possibility for an unforeseen electronic throttle control malfunction, causing a vehicle to accelerate contrary to driver input. Although very unlikely due to various built-in electronic safety protocols, unforeseen circumstances could still exist that could cause this type of malfunction.' hyundai introduced `this critical safety technology' on 100 percent of its new models anticipating the government might mandate it sometime in the future. 'with hyundai's brake pedal throttle override capability, any brake pedal input by the driver, even with a runaway throttle condition, completely overrides any throttle malfunction,' stated the director of certification and compliance affairs for hyundai's american technical center, inc. (hatci), said in a statement. 'it is no longer possible to have increasing engine power once the brake pedal is depressed by the driver. This adds a reassuring, incremental safeguard of control for hyundai drivers.' per consumer affairs, 'local police agency suggests that hyundai accelerated on its own before fatal crash'. Special crash investigation.

My 2009 hyundai santa fe has stalled more than 4 times while driving since 2010. It loses power without warning rendering the vehicle unsafe and not able to be driven. The first time in 2010 it stopped while on the exit ramp of a highway doing about 50 MPH. The car was brought to the dealership and they "could not duplicate the problem" so they did nothing. Brought same vehicle back to dealership in 2011, 2014 and 2019. Each time we are told "could not duplicate at this time". The most recent on august 7, 2019 they replaced the alternator and battery commenting that "vehicle now operates normally. Vehicle does not stall". The vehicle has since stalled again during driving. The dealership will only look again at the vehicle at the cost of $100.00 per hour. We have contacted the corporate office and they were not helpful, in fact rude and hung up. After reading so m;any complaints on just this site I hope our government can help get hyundai to be responsible for their vehicles before someone gets hurt or killed.
