NHTSA Complaint #11717330 — 2007 HYUNDAI SONATA

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.
