The contact owns a 2009 Hyundai Santa Fe. The contact received a notice for TSB: [redacted] and the vehicle was taken to the dealer where the campaign was completed.

[redacted] We took out Stanta Fe to the Hyundia Dealership in Columbia, TN 38401. The installed a new rover cover gasket left and service kit. The purpose was to stop oil from leaking into the alternator. 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. …
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. …
Alternator failed Due to valve gasket leaking, Hyundai issued a recall during time vehicle was in probate, I did not receive notification and had the valve gasket, manifold gasket, and alternator replaced.

The claim was transferred to claim reimbursement 8/29/2022, I received an email stating it would be 3-4 weeks for reimbursement. I called 9/29 and was informed it would be 120 days from submission date, On 12/6 additional information was needed. I was not notified, and saw the status changed, and called for update on 12/13. I submitted the same day. On 12/22, I received the repayment notification, but not the amount. …
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.
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.
Right front fog light inoperative. Dealer replaced halogen bulb. Within a few days fog lamp overheated causing bulb socket and lens bulb holder to completely melt down causing bulb to fall down onto the inside of the right front bumper and burned two holes through bumper almost causing a fire as bulb was still functioning. No circuit breakers or fuses blew. Dealer states this has happened before to other vehicles and now dealer needs to replace both socket & wiring and complete lens body.
While traveling on the interstate at speed (70 MPH), car stopped responding to throttle with no warning. As I merged to right lane, car died completely and I had to maneuver to shoulder with no power. Stuck here with wife and 2 toddlers until towed to mechanic. The alternator was dead and had to be replaced. One year later, same thing (luckily not on interstate this time, and warning light did come on this time). Alternator replaced again. Later in 2015, Hyundai announced a maintenance campaign (#936), and I was reimbursed for initial 2 events, and local dealer completed the required maintenance in nov 2015. 2 years later, same thing: warning lights, oil on alternator, etc. Local dealer again completes the work (thankfully at no charge to me). As of today, oil is on the alternator again, and I feel it is only a matter of time before the issue occurs again. …
Contact owned 2009 Hyundai Santa Fe sport utility vehicle. At 2 pm 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. …
I am having the issue with the gas gauge, where a short time after filling up the tank, the gauge drops to empty and then the check engine light comes on. I believe this problem was caused by the same issue as a recent recall, where oil was dripping on the alternator. Just a couple days after I received the recall for that issue, I began having electrical issues. My radio came on and off, my windows rolled up and down very slowly. On my last drive home, my electronic brakes stopped working, the steering was hard and the transmission began shifting up and down before I was finally able to pull over and have the car towed. Upon my drive home from the dealer after the recall repair, I noticed that a headlight was newly burned out. In less than a week, the other headlight burned out. …
