The rocker arm of the engine has failed, causing a repair for a full engine replacement. The car has always undergone maintenance timely, and upon inspection by the dealership technician, the report state the vehicle was up to adequate level. There were no symptoms before the issue occurred, only the sudden catastrophic engine failure.

I am submitting this complaint due to a potential safety-related engine failure that occurred while my vehicle was under dealership repair. My vehicle was dropped off at Huffines Hyundai on October 2, 2025, for a fuel injector issue and has remained under the dealership’s exclusive possession since that date. I have not driven or had access to the vehicle after drop-off. During the repair process, I was informed by dealership staff that an injector was seized in the fuel rail and difficult to remove. Although the injector replacement was documented as a short repair, the work was delayed and completed on October 16, 2025. Immediately following this repair, on October 17, 2025, the engine was documented by the dealership as having low compression. I was not notified of this condition until October 27, 2025. The engine damage occurred while the vehicle was under dealership control and immediately following a repair involving seized components. The diagnostic documentation provided to me is incomplete and does not include compression PSI values or supporting data. I am concerned that improper repair or handling may have caused internal engine damage, resulting in a condition that could lead to engine failure or unsafe operation. Due to the circumstances and lack of transparency, I do not feel the vehicle is safe to operate and am concerned about the risk of engine failure.

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.

While driving the car the engine died, locking up both the gas and brake pedals. The car had to come to a stop on its own, my wife could not depress the gas or brake to stop the car. She was going through an intersection and narrowly avoided a major accident! The battery light came on, the check engine light and the car started to fill up with a smell of burning plastic and gas. When trying to turn the car back on after turning it off it would start with a major shake and bang then turn back off. All warning lights stayed on. Battery was fully charged still. Autobody shop found engine issues in their pre scan before sending it to Hyundai to warranty it as it only has 6,626 miles and is 2 years old. There was a warning of low battery while we were on vacation and the car was sitting for a few days. And a sluggish start when it sat for few days like the battery was low, but it wasn’t based on the volt meter.

I have a 2022 Hyundai Tucson with about 15k miles on it. I have had it serviced twice for oil changes and the recommended manufacture recommended maintenance. However, I have noticed a SIGNIFICANT loss in power upon acceleration with this vehicle. My new car drives very rough and this is a safety issue due to the fact when entering the interstate, the car will not increase speed as requested putting myself and others on the road in danger. Additionally, simple maneuvers like turning into cross traffic are of concern because the vehicle doesn't respond to acceleration when accelerating from 0mph as well as in stop and go traffic. There are no engine lights or codes that I can visibly notice but even in sport mode the acceleration of the vehicle is not responsive. This is a KNOWN issue at Hyundai as one local dealership offered me a service visit 6 months out because they are so overbooked with these issues. A quick Google search also brought up numerous owners experiencing similar and and escalated issues to include complete engine failure and vehicle overheating. This vehicle needs to be recalled immediately! I experience this loss of power EVERY SINGLE TIME I DRIVE and I don't feel safe driving my new car anymore. I have mentioned this to my dealership and they are going to take a look at it today. Occasionally, the car will also indicate to me that I should keep my hands on the steering wheel when I typically drive with BOTH hands on the steering wheel.

At highway speed engine began stumbling and shaking car and stalled the car within 5 seconds bring car to halt. Engine would not restart properly, would not settle at idle rpm with rapidly inconsistent rpm shaking the car and then stall within 5 seconds. Any attempt to place car in drive immediately stalls car. After attempting 50-60 bump starts to get car off road the check engine light and error message about engine control system error eventually showed. Hyundai towing refused to take inoperable car to dealership for warranty repair of 1000mi car, instead left it at our apt parking lot. The engine failure left the driver and other motorists in danger as unable to move stranded car off 50mph busy main road on cold dark snowy evening. Dealer reports they are “swamped” with repairs and cannot see an inoperable car for at least 2-3 weeks and no loaners or rental could be provided. There were no warning lights or warning during initial stall or subsequent restarts. Error message and check engine light did not light until attempting 50-60 bump starts trying to get car off road and a hazard to occupants and other motorists.
