I have a 2007 Hyundai Sonata SE v6 3.3L and on January 9th, 2026 I had an incident where on the road my charging system light on signifying alternator failure. I made it home, but the battery was dead which was recently purchased. After recharging the battery I conducted tests with a multimeter and have determined the alternator has failed. The alternator has accrued a coating of oil overtime that was unknown until my research into the matter of root cause. Hyundai manufactures a V6 engine family called Lamba in which a version called Lambda MPi G6DB was introduced in 2007–2009 Hyundai Santa Fe (CM) and 2005–2009 Hyundai Sonata (NF) models. In 2023 Hyundai issued a recall for the 2007-2009 Santa Fe for a Cylinder Head Cover Oil Leak Repair where oil drips from the valve cover directly onto the alternator causing it to fail. I have a 2007 Hyundai Sonata 3.3L V6 engine where the very same issue has occurred with photo evidence that has caused my alternator to fail and have tested the issue. This vehicle model was not included in the recall despite the engine being exactly the same as the recalled model, the year being the exact same as the Santa Fe, and the alternator in the exact placement where the oil drips into the alternator causing failure just like the Santa Fe recall. The Santa Fe recall with the same issue is documented with National Highway Traffic Safety Administration below: [XXX] Hyundai has yet to issue the same recall for the Hyundai Sonata brand of vehicles, despite the same issue occurring and a known issue with the Lambda MPi G6DB engine design effecting multiple models in the same way documented across multiple owners of these vehicles with various fixes suggested on Youtube, Reddit, and enthusiast forums for this engineering failure that causes considerable risk if the alternator fails in operation on roadways.

Red “airbag” light on dash illuminated while driving. Code read as B1706: passenger buckle pretensioner. May have been covered under Hyundai’s 15yr/250k warranty but owners never notified since not official recall. Although, this defect may not affect airbags themselves it causes “airbag” light to remain illuminated until addressed. Driving with the “airbag” light continuously illuminated may pose risk to unsafe conditions due to unknown new airbag codes since “airbag” light already illuminated with buckle pretensioner code B1706.

I have been encountering issues with my 2007 Hyundai Sonata SE in the following manners: 1- At times the brake lights will be on and the car will have anyone inside. 2- My ESC OFF light comes on will not go off. 3- When using my headlights the cruise control will not work. (Specifically when the automatic lights would come on the cruise goes off) 4-At random times the key will not turn. All the above mentioned issues concern the electrical system!, Speed Control!, and lighting systems. All are available for inspection upon request. My safety and the safety of others has been put at risk because of system failures causing the car to operate improperly and dangerously. I have not had the extra money to take it to the dealership. No other reports have been made. The only warning light is the ESC OFF light comes on occasionally. This light began coming on 6 months ago.

I recently purchased this vehicle from my father. I believe there is a faulty sensor in the passenger airbag sensor for their OCS (occupant classification system). The warning lamp for 'Air Bag' stays on when operating the vehicle. When starting the vehicle with no passenger, the lamp to show there is no passenger comes on but then turns off. It does the same thing with a passenger in the seat. The lamp to show there is no passenger used to stay lit, when there is no passenger. I have tried to address the issue with Hyundai about 2 or 3 times by calling customer service by phone and they told me all 3 times that there are no "open recalls for this vehicle at this time." But I can clearly see through records that recall no. 08V161000 addressed this very issue. I will attempt to make an appointment with one of their Hyundai dealerships but I believe there is a safety issue here. Thanks!

I took the car in for a recall/warranty repair on 3/28/2021. The part (seatbelt/airbag sensor/pre tensioner) has still not been delivered to the dealer so that they can repair the vehicle. The part being defective prevents the airbag sensor from operating correctly and, as such, the airbags will not work in the event of a collision. This car is my daily driver and has largely been parked idle for 12 months. For the entire year, I have been fighting with their corporate customer support team and there has been no progress whatsoever on securing the part. They have given me numerous dates for the part to arrive. None of them have been met. No new date has been provided. The dealer blames Hyundai Corporate, Hyundai Corporate blames the 'distribution centre' and so on. The car is unsafe with no airbags and there is no resolution in sight.
