NHTSA complaint #11696131

Owner complaint summary

I am submitting this complaint regarding an ongoing and dangerous issue with my 2022 Hyundai Tucson involving repeated fuel injector failures that have caused the vehicle to stall and lose power while driving, without any prior warning indicators. The first incident occurred in October 2023, at approximately 16,000 miles, when the car suddenly died while I was driving. There were no warning lights or signs of a problem before the stall occurred. The vehicle had to be towed to the dealership, where they replaced two fuel injectors. Just two weeks later, the same issue happened again—the car died while driving and was towed back to the dealership. The remaining injectors were then replaced. Unfortunately, this problem has continued. In November 2024, at around 26,000 miles, the vehicle again stalled while driving, with no warning, due to another fuel injector failure ( more failed injectors). Most recently, on October 18, 2025, with 31,000 miles on the odometer, my Tucson lost power and died while I was merging onto an interstate—once again with no warning or alert of any kind. I am still waiting for confirmation of how many injectors have failed this time. This is an extremely serious safety hazard. Losing engine power unexpectedly, especially while merging into highway traffic, puts both the driver and others on the road at significant risk of a collision or serious injury. Despite multiple occurrences, Hyundai has not identified the root cause of the injector failures and continues only to replace the faulty parts, which clearly does not resolve the underlying issue. It is unacceptable that a relatively new vehicle would experience repeated fuel system failures of this nature, and it is clear that there is a systemic defect affecting safety and reliability. I urge the NHTSA to investigate this issue to determine whether other Hyundai Tucson owners are experiencing similar failures and whether a recall or safety action is warranted.
