2022 Hyundai Tucson fuel/propulsion system problems

“My car suddenly broke down on the side of a busy highway halfway through my workday. When attempting to restart it, all warning lights came on on the dashboard and I could see white smoke coming out of the exhaust pipe while the car shook. I had it towed to the nearest Hyundai dealership and they confirmed it was broken fuel injector(s). I do not have the broken piece to show as it is with the dealership. It has not been examined by police or insurance. No warning lights came on until after the car had suddenly slowed to a stop and I attempted to restart it.”

“Vehicle Fuel Injector code P053F84 Reading on 9/9/26, this is the second time vehicle was taken to the dealership for the exact same problem, the idle button in orange, and displayed, first visit while vehicle within warranty limits technician stated couldn't find anything wrong, now vehicle is out of warranty and dealership wants $1300 to fix the same issue.also the Engine was hesitating at each occurrence.”

“In April 2026 (29,805 miles) I was on an interstate underpass U-turn and when I went to accelerate from the U-turn, the vehicle “revved”, had difficulty accelerating, and appeared to not go into the next gear for a roughly 10 seconds, meaning I was unable to accelerate and get out of the way from oncoming traffic. Traffic slowed and the vehicle suddenly returned to normal (no warning lights appeared) and I drove home cautiously with hazards on. When attempting to leave less than 45 minutes later, the vehicle started, then as I placed it into drive, it began lunging and the check engine light appeared. Because it was running rough and kept lunging, I parked and had it towed to the dealership. The DTC code listed was PO30300 (DTC system powertrain and subsystem EMS). Per the dealership, fuel injector #3 was bad and needed to be replaced. When I picked up the vehicle, notes stated “ GDI FUEL INJCTR REPL (ALL4)”. I picked up the vehicle after the repair. In August 2026 (30,923 miles), with less than 1,000 miles driven since repair, I started the vehicle and it immediately “died”. I restarted it and the check engine light came on and it began lunging out of my…”

“Fuel injector went bad causing vehicle engine to misfire and shake rapidly. Check engine light is on. The vehicle only has 40,000 miles on it. Seems to be a very common concern for this make and model and roughly the same years. Will not accelerate instantly and will surge a bit when it does. Will still shake when the vehicle is idle.”

“While driving the car stalled and then the engine shutdown, caused by a misfired fuel injector. Myself and the passengers in the car were minorly safe, as this incident occurred while driving through the Yellowstone National park; having to pull over on the side of the road with no shoulder. The Woody Smith Hyundai Dealership in Idaho Falls confirmed that the feul injectors had misfired, and then replaced them. Prior to the failure, there was no warning until the car was actively stalling and failing (battery light and check engine light came on).”

“I became aware of a Technical Service Bulletin that Hyundai published in Jan 2025 acknowledging that many vehicles (of which mine is one) have a faulty fuel injector and it will fail. Hyundai elected to not issue a recall on this issue so the public has no idea they are driving vehicles that are just awaiting for a malfunction in their engine. It appears the reason Hyundai is doing this is because fuel injectors are only covered on the manufacturer’s limited 5-year 60,000-mile warranty so they are hoping the faulty injectors last long enough to get beyond that point and customers don’t know the injectors were even faulty to begin with (because TSBs are not public knowledge). Hyundai can then charge for full repairs and omit admittance that the injectors were faulty and blame it on wear and tear. Mine failed beyond 60,000 miles and I am in this predicament. I imagine most customers with 2022 vehicles have not driven as much as me and haven’t had this come up. It seemed like something I should inform someone about. Do with this what you wish”
