The contact owns a 2008 Hyundai Santa Fe. The contact stated that the vehicle was taken to a local dealer for an undisclosed recall repair, and the contact was informed that the valve cover gasket, and the alternator were faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 88,000.
In October 2021 the alternator failed due to an oil leak from the valve cover gasket. I paid the local Hyundai dealer to replace the alternator and they also said the battery was damaged because of the failed alternator so I paid for a new battery as well. The dealer never mentioned the recall on this vehicle for the leaking valve cover and did not disclose that the leak was known to cause alternator failure. I later learned of the recall and had the valve cover repair performed under the recall. However, Hyundai has refused to reimburse me for the alternator repair that I had already previously paid for, and likewise have refused to reimburse me for the battery. Clearly the problem was due to the known defect that resulted in the recall, so I am obviously entitled to compensation for the out if pocket repair expenses. Please advise me how to proceed.
I took the car to get this recall done: Hyundai has decided to conduct a service campaign to inspect (and if necessary replace) the alternator and replace the front valve cover gasket on certain 2007-2009 model year Santa Fe vehicles. The recall was done, replacing the gasket and alternator. 2 years later the car started to stall in the middle of traffic. I returned to the dealer, dealer inspected and reported "oil found on the new alternator and oil leak found on the real valve cover gasket". I have been going back and forth on the phone with Hyundai costumer care. They said they will not redo the recall. It was not done correctly and slowly leak again. the vehicle now cut off everyday specially when i stop and go at short drives. It has also cut off in traffic. making it very dangerous. But Hyundai is telling me nothing for them to do.
Brought 2008 Hyundai Santa Fe to Carlsbad Hyundai dealership on 12/22/23 for Service Campaign 976, due to oil leaking from the front cylinder bank's valve cover onto the alternator. Oil could damage the alternator resulting in illumination of the charging system warning lamp and disablement of the charging system. If the vehicle is continually driven without recharging the battery, the engine will eventually shut off, increasing the risk of a crash. Dealership said the vehicle needed to be fixed but they needed to order parts and that it would take 2-3 wks. It has now been over 6 months. I have called the dealership and Hyundai America multiple times all to no avail.
Engine rattles noise when starting the car after sitting for more than an hour it makes that sound another issue is that when i turn the headlights on all interior lights shuts off including the instrument cluster radio and ac climate control buttons
My car has a recall, and the dealership is unable to fix it. There is also an issue with the oem control module that they are unable to get the part and unable to fix this because they do not have the correct software.
I have taken my car to my local dealership for the Service Campaign 976 (Oil Gasket leak) back in Nov 2023. Ever since then my car has had starting issues until one day it needed a jump start in 2024 during the summer. Didn't think anything of it at the time, until the beginning of 2025. Car needed a jump start in the winter before leaving for work in the morning and before going back home from work. My brother who is a auto mechanic suggested I needed a new battery by now so I did that. Once I replaced the battery on my car I noticed that I didn't have headlights, power steering or heat working in my car. He came to my home and checked my engine and noticed that my alternator was covered in oil. I remembered that I took my car to the dealership for this issue with the Service campaign. I've been back and forth with this issue between the dealership and corporate to look at this issue. …
