2008 Hyundai Santa Fe electrical system problems

“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”

“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. The dealership can't provide any photo proof or documentation stating what work was done. The dealership claimed that Hyundai doesn't need photo proof as of 2023 and started needing it in 2024, they simple state that the work was done and sign the car off on the recall. I don't…”

“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.”

“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.”

“The contact owns a 2008 Hyundai Santa Fe. The contact stated that the vehicle was experiencing difficulty charging. The contact stated that while driving 50-60 MPH, the vehicle stalled. The contact was able to pull to the side of the road. The contact stated that the failure had occurred several times while driving on the highway. The vehicle was able to be jump-started. The contact stated that a mobile mechanic had inspected the vehicle and informed the contact that there was oil leaking onto the spark plugs. The contact stated that the vehicle was chugging while driving. The contact became aware that the VIN was included in Hyundai Campaign Number: 976. The vehicle was taken to the dealer for repair. The dealer diagnosed that the valve cover gasket was leaking onto the alternator and onto other unknown parts. The dealer replaced the valve cover gasket and the alternator under Hyundai Campaign Number: 976. The contact stated after driving 7-8 minutes after picking up the vehicle from the dealer, the contact noticed an abnormal odor and smoke coming from underneath the hood. The contact pulled into a gas station and parked the vehicle. The manufacturer was…”

“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.”
