I am the original owner of a 2023 Hyundai Tucson with approximately 56,000 miles. I am reporting a recurring safety issue involving sudden loss of engine power and acceleration while driving. I previously experienced a similar incident at approximately 50 mph, when the vehicle struggled to accelerate. Hyundai of Cumming inspected the vehicle and, on XXX, at 44,199 miles, replaced the high-pressure fuel pump and fuel pipe (Repair Order XXX). Despite this repair, the same issue occurred again on XXX. The engine struggled to gain RPM, and the vehicle would not accelerate properly. There were five occupants, including my [XXX] daughter and her [XXX] friend. Fortunately, I avoided an accident, but this could have resulted in a serious collision. I regularly use this vehicle for family transportation, including school and daily activities, and my commute involves approximately 25 miles of driving each way, including highways. Unexpected loss of acceleration is extremely dangerous, particularly when merging or keeping up with highway traffic. The vehicle is currently parked because I no longer consider it safe to drive. I am requesting an investigation into this recurring loss-of-acceleration issue in 2023 Hyundai Tucson vehicles, including whether a defect involving the fuel delivery system, high-pressure fuel pump, fuel pipe, or related components could cause sudden loss of engine power while driving. This problem poses a serious risk to the driver, passengers, and other road users. I am also attaching the hyundai repair invoice from last year for your reference.

SAFETY DEFECT SUPPLEMENT TO the federal safety agency COMPLAINT #11685540 | VIN: [XXX] | MILEAGE: 27,370 ​This filing supplements Complaint #XXX regarding an uncorrected, compounded steering safety failure following the catastrophic detachment of the steering column while driving on XXX (Repair Order #XXX). ​COMPONENTS FAILED: Steering column assembly, footwell closeout shield, dashboard lower crash pad structural frame, and push-start switch. All components and vehicle are available for immediate inspection. ​SAFETY RISK: Following an invasive warranty teardown for an ignition switch failure under R/O #XXX at [XXX] Hyundai, the vehicle was released in an incomplete, hazardous condition. The factory lower footwell closeout shield was completely omitted, leaving the rotating intermediate steering shaft, universal joint, electric power steering motor, brake clevis linkage, and wiring harness fully exposed directly above driver foot controls. This creates a severe entrapment and mechanical binding hazard. An unauthorized exterior screw was drilled directly through the finished lower crash pad trim to pinch broken internal plastic tabs together, and hardware was left rattling inside the column housing. ​DEALER CONFIRMATION & RECORD FALSIFICATION: Management dismissed the exposed shaft. On R/O #XXX Line 3, the dealership falsified the narrative as "customer needs screws put in behind steering wheel" under an engine line to conceal shop rework. Authorized remedy has completely failed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2023 Hyundai Tucson Limited, 2.5L GDI, Alabama-built (VIN 5NMXXXXXXXXXXXXXX), built [XXX]. On [XXX], at about 37,550 miles, the check engine light came on flashing and the engine ran rough while I was traveling in Canada. My scan tool showed P0300, P0302 and P0304 (misfires on cylinders 2 and 4). On July 6, 2026, Experience Hyundai in Charlottetown, PE (service order 92XXX) replaced one ignition coil under warranty. No fuel injector leak test was performed. The misfires returned. On [XXX], at 39,409 miles, my scan showed P0302 active and P0304 pending. The car also had extended cranking after sitting and the check engine light was on. I was told I could keep driving the car unless it started to jerk or engine light started to flash, then immediately stop driving it and have it towed. On September 25, 2026, the car was towed to McGovern Hyundai Route 2, Leominster, MA (invoice 148XXX). The dealer found all 4 fuel injectors leaking and replaced them under warranty with injector service kit 35399-2S133QQH. My vehicle is outside the production range of Hyundai TSBs 23-FL-002H-1 and 26-FL-001H, which cover this injector failure only for Alabama-built Tucsons produced through July 11, 2022. Yet it failed in the same way. I am concerned the defect extends beyond the bulletin dates and that a sudden misfire could cause loss of power in traffic. There is no recall for this condition. The dealer found all 4 fuel injectors leaking, even though only cylinders 2 and 4 had set misfire codes and replaced them under warranty with injector service kit 35399-2S133QQH.

The car was working perfectly fine I drive it for work all the time and one day it started shaking weirdly. A couple days later the check engine light turned on. It was throwing the code that was pointing to "misfiring in the 3rd cylinder" We changed all the spark plugs, 3rd cylinder coil pack, and switch the coil pack to see if it would say a misfiring in a different cylinder. We then took it to a mechanic saying that it is the high pressure fuel injectors and that he has seen this problem with other Hyundai Tucson around the same year as us and that there was a bulletin on it.

The right rear shock absorber failed and was replaced under warranty at approximately 22,000 miles. The car was making noise, the shock was leaking, and not working properly. The dealer admitted to problems with rear shock absorbers failing at low mileage on Hyundai Tucson Hybrid SUVs 2022 through 2025 Tucson Hybrids. The left and right rear shock absorbers are the same part number so we now expect the left side to fail but the dealer will not replace the left until it fails.

Under Hyundai Recall 290, the dealership permanently removed the functional trailer light wiring harness and replaced it with a nonfunctional rubber dust cap. A Hyundai case manager informed me that a replacement harness is "in development," but official the federal safety agency remedy filings show the cap is the final remedy, resulting in the permanent loss of a factory feature I paid for. The removal of towing functionality without a clear timeline for a safe replacement parts remedy constitutes a failure to properly correct the vehicle defect.
