2022 Hyundai Santa Fe Fuel System Problems

Your panoramic sunroof suddenly exploded while you were driving at 50 mph, sending glass shards into the cabin with no apparent impact or cause. Separately, your check engine light came on and the engine went into limp mode, which was caused by a faulty fuel injector that needed replacement. The sunroof issue remains undiagnosed, while the fuel injector has been replaced to restore normal engine operation.

Your 2022 Santa Fe is experiencing repeated fuel injector failures that cause hesitation and jerking when you accelerate. The check engine light keeps coming back on even after the dealership has replaced multiple fuel injectors—first one, then another, and there's a technical bulletin indicating all four may need replacement. The dealership will likely need to replace all four fuel injectors and investigate why they're failing repeatedly.

Your fuel injectors have failed multiple times and required replacement three times already. This is causing problems with how fuel is delivered to your engine. The fuel injectors will likely need to be inspected and replaced again by a mechanic.

While traveling out of state, my 2022 Hyundai Santa Fe (2.5L) experienced a sudden loss of power and rough running during acceleration to pass; check engine light came on. Independent shop pulled code P0302 (cylinder 2 misfire). Vehicle became unsafe to drive and was left at a Hyundai dealer in Indiana. I later learned Hyundai issued TSB 25-FL-001H (Jan 2025) for 2.5L GDI injector internal filter breakage that causes misfires and directs replacing all four injectors. Parts were quoted up to three weeks on backorder. This sudden power loss during highway passing presents a safety risk (inability to accelerate/merge). Vehicle is under 60,000 miles.

Vehicle failed to accelerate while operating on the highway. Pulled over and shut vehicle off and smelled gas. Vehicle would not stay started. Towed to dealer and was told it was a defective fuel injector. All injectors were replaced. Apparently this is a known problem. This could have been extremely dangerous if I wasn’t able to pull over. Hyundai should issue a recall to replace these defective parts.

The vehicle was towed to the dealer, who determined that the fuel injectors needed to be replaced, but the parts were on backorder. The vehicle was then towed to a second dealer, AutoNation Hyundai Mall of Georgia (3445 Buford Dr, Buford, GA 30519), who determined that the fuel injectors needed to be replaced and informed the contact that parts were still on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 30,000.

I filled up my gas tank and the digital guage was on 266 miles. After I filled up, it was the exact same mileage on the dashboard. It did not move after putting in about 4-5 gallons of gas.
