I am writing to formally report an incident involving the service department at Lakeland Hyundai (1500 W Memorial Blvd, Lakeland, FL 33815). My 2007 Hyundai Santa Fe was brought in on 12/31/25 for an active engine recall involving the Cylinder Head Cover Oil Leak Repair (Recall Code 976 / Campaign 24-01-026H). The vehicle was driven into the dealership in proper working condition. I was later informed that allegedly stripped bolts for the cover would require an out-of-pocket cost of $483.36, despite this being a recall repair. There was also a required Upper Timing Chain Guide repair quoted at $58.38 to complete the recall work. When I was called in on 01/12/26 to pick up the vehicle for completed work, I was charged $29.99 for a Multi-Point Inspection related to the recall, yet no documentation or billing was provided for the timing chain guide repair I was told was completed. …
My vehicle had an oil leak from the front cylinder bank valve cover onto the alternator. the oil damaged the alternator resulting in illumination of the charging system warning lamp and disablement of the charging system. On 11/09/2021, the engine light came on and my car turned off. I had it towed to my mechanic and on 11/10/2021 he replaced the valve cover gaskets, alternator and belt. On 12/2023, I found out there was a manufacture recall related to the valve cover. I placed a claim in 12/2023. They have asked for several versions of documents and then stop communicating and eventually deny/close the account. I have filed approximately 4 claims and they stop communicating. The last claim was filed on 1/2/2025 and I have only received an email stating "Thank you for contacting Hyundai Motor America." I have tried to ask for an update and no response. …
In 2015 Hyundai issued service campaign 936 for 2007-2009 Santa Fe valve cover & alternator due to the valve cover leaking & dripping oil onto the alternator, potentially damaging the alternator resulting in the charging system becoming inoperative. My 2007 Santa Fe was repaired under this campaign. Now with less than 30K miles since the repair the same problem exists, the valve cover is leaking oil onto the alternator again. I've contacted my local Hyundai dealer but they refuse to repair the issue under the campaign a 2nd time. The issue was detected by the local dealership during a routine oil change & they advised me that the cost to replace the valve cover gasket & the alternator would be in excess of $1,000.
The E .C. M. PART# 39110-3C561 started faulting out, causing stalling abruptly while stop at an intersection an merging into traffic.This events were randomly happening causing higher risks of accidents. I took the vehicle for service an was informed that the "ECM" was causing this faults. The vehicle had the check engine light on during this time. The service shop advised me to bring the vehicle in to the Hyundai dealer, because the problem is likely to increase. The Hyundai dealer verify that the "ECM " is faulty an extremely difficult if not impossible to find. This faulting "ECM " part has literally but my vehicle totally useless.
UNKNOWN Went to the grocery store and vehicle was working fine. Upon leaving the store, started the car, ESC OFF light was on and when I went to press the brake to put the vehicle in reverse, the gearshift was locked and I couldn't move the gear. Long story short, I had to get my vehicle towed to the house as the vehicle is non-drivable at this time. Kelly's Blue Book indicated there were a few Hyundai recalls related to the ESC but my make and model was not affected but clearly I believe it is based on my experience and find this very unsafe.
Brake/stop light switch located behind the brake pedal sticks causing the gear shift to not be removed from or into Park. Hyundai issued Recall #110 for this issue but the recall does not cover all versions of 2007 Santa Fe even though the issue occasionally occurs on non recalled versions.
Car made rapid click failed turn signal sound while driving without signal activated and haphazardly activated left signal independent of driver. Sideound stopped if signal activated. As approached busy traffic area (airport), steering column started smoking and burning smell filled passenger cabin. Hyundai dealer acknowledged is manufactuer switch defect, without safety fuse to prevent fire on overheating, but is charging $250 to repair and keeping my only car for at least a week while ordering another part (which as it is the same defective part is just as likely to eventually fail and risk a car fire while driving my kids). Dealer says Hyundai accepts no responsibility for the defective part. A complaint 10629458 was filed for what sounds like the same defect in a 2010 Santa Fe with similar abdication of responsibility by Hyundai. Things that cause cabin fires should promp a recall.
Friday, aug 12, I parked the car around 6:30 pm. Around 8:40 am, Saturday aug 13, neighbors rang my door bell and banged on the my door. The Santa Fe was on fire. My insurance company found no evidence of arson. The car parked for around 14 hours caught fire. Researching online, I found numerous comments from other Hyundai owners who faced a similar experience.
2007 sante Fe alternator issue. Post recall fix, oil leak still happening and this time the alternator almost caught on fire. Smoke started pouring out from under the hood.
