2022 Hyundai Tucson

The contact's wife owns a 2022 Hyundai Tucson. The contact stated that his wife reported that the vehicle shuddered significantly and failed to exceed 30 MPH while driving. The check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the fuel injectors were leaking, and the dealer determined that the fuel injectors needed to be replaced. The dealer informed the contact that the manufacturer had redesigned the fuel injectors due to the known failure. The dealer informed the contact that the repair could not be covered under the extended warranty because the vehicle had exceeded the required mileage. The contact was informed that parts needed to be ordered to repair the vehicle. The vehicle had not yet been repaired. The contact related the failure to TSB Number: 22-FL-002H. The manufacturer was notified of the failure, and a case was filed; however, no assistance had been provided. The failure mileage was approximately 65,000.

2022 Tucson (NX4, Alabama built) 2.5L Engine experienced a catastrophic failure leading to Hyundai dealer diagnosis that "Cylinder #3 is not contributing properly," which requires a full engine replacement. The vehicle is currently located at home and is available for inspection upon request. The engine scuffing has resulted in a severe loss of power contribution from Cylinder #3, leading to potential for sudden engine stall or complete loss of motive power while driving. If the engine seizes or stalls at highway speeds or during a critical maneuver (e.g., merging onto a freeway or turning across traffic), it creates an unreasonable risk of a rear-end collision or a catastrophic accident, endangering both the driver and others on the road. Furthermore, the internal mechanical failure creates a significant FIRE RISK due to potential oil leakage onto hot exhaust components. The problem has been confirmed by Hyundai Service Center in El Paso, Texas and three independent service centers in Arizona and Texas. All four assessments concluded that the vehicle requires a full engine replacement due to severe internal damage. Inspected by Hyundai Service Center in El Paso, TX. Despite confirming failure, Hyundai refuses to provide critical diagnostic data (Power Balance Test, Endoscopic Inspection, DTCs) and the determined root cause. This refusal hinders warranty transparency. The Check Engine Light (CEL) did not illuminate. Symptoms appeared late September 2025 at approximately 88,000 miles (audible engine noise/scuffing, rough idle, significant power loss). This failure at non-typical mileage demonstrates a severe internal defect and a safety system malfunction (failure of the ECU/CEL to adequately warn the driver). Note: Dashcam video documentation of the engine failure symptoms (audible noise and power loss) is available and can be presented to investigators upon request.

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.

On August 14, 2025, at approximately 12:40 AM, my 2022 Hyundai Tucson Limited suddenly stalled while driving and became completely non-functional. The vehicle had about 25,000 miles at the time. This left me stranded on the highway in the middle of the night, creating a serious safety risk for myself and other motorists. The vehicle was towed to a Hyundai dealership. The dealer claimed the issue was caused by “carbon buildup” and stated that the problem would only be considered “repaired” if I paid for a fuel injection cleaning and fuel induction decarb service (about $500). These services are not listed in the Hyundai factory maintenance schedule, and no diagnostic evidence (photos, test results, or measurements) was provided to support the claim. Because the stall made the vehicle inoperable, I believe this should have been handled under warranty. Instead, I was pressured to pay for optional services in order to have the safety issue resolved. Safety Risk: The vehicle stalled without warning at highway speed, placing myself and others at risk of collision. Based on the dealerhip this needed to be serviced every 20k miles and hyundai deosnot recommend to consumers for some reason..

I have had 3 fuel injectors go out on my 2022 Hyundai Tucson. When this happened it was completely random and my car would stall and I would be stuck on the side of the road. I have had to miss work due to this happening. They told me that they are only able to replace the broken one each time instead of replace the all 4 while covered under warranty. They also told me that fuel injectors breaking is a common problem in 2022 and newer Tucson's as they are higher pressure systems than previous models. Im worried that this is going to keep happening and I'm going to keep breaking down due to fuel injectors breaking and end up stranded somewhere.

Fuel injector failure. Car was losing power completely when pressing the gas pedal then would suddenly catch and go again. Then go very slowly with little power, almost got into an accident because of the loss of acceleration. They replaced the fuel injectors and it is now happening a second time with the check engine light coming on again. A RECALL NEEDS TO BE MADE! SEVERAL OF THE SAME COMPLAINTS ON HERE!!!!!!!

FUEL INJECTORS FAILURE..... SECOND ONE IN A LITTLE OVER A YEAR. BROKE DOWN ON MAJOR HIGHWAY.. TOWED TO HUNDAI IN CAPE GIRARDAU AS IT IS UNDER POWER TRAIN WARRANTY. ONLY TO BE TOLD THAT THIS IS NOT PART OF THE POWER TRAIN EVEN THOUGH IT IS IN THE ENGINE. KNOWN ISSUE,, LAST TIME THE MECHANIC TOLD US IT WAS PART OF POWER TRAIN. THERE HAVE BEEN SERVICE BULLETINS ON THIS ISSUE.
