“On August 19, 2026, at 76,170 miles, the engine in a 2012 Hyundai Sonata GLS suddenly lost power and shut off while the vehicle was moving on gas station property. The driver had traveled approximately 10 feet before the engine stopped. Repeated attempts to restart were unsuccessful; the engine would not crank. The driver shifted into neutral and pushed the vehicle to a safe location. Before the failure, the vehicle was running smoothly, with no warning lights, warning messages, unusual noises, or other symptoms. There was no collision, injury, smoke, or fire. The sudden, unannounced loss of propulsion created a safety concern because the vehicle could no longer move under its own power. Fortunately, the driver was still on the gas station property and was not blocking traffic. An independent repair shop inspected the vehicle and confirmed that the engine was mechanically locked up. The vehicle was subsequently taken to an authorized Hyundai dealership for inspection. The dealership’s service adviser reported lower rod-bearing failure. Hyundai later denied engine-replacement coverage, citing neglect and missing maintenance records. That denial is being disputed…”
“Based on what I experienced, the fire appears to have resulted from an internal mechanical or electrical failure that occurred without warning while the vehicle was in motion. No prior issues or dashboard alerts were present at the time, and there was no external impact or damage that could explain the fire.”
“I am reporting a total manufacturer parts shortage. My 2012 Hyundai Sonata GLS is part of the Hyundai Anti-Theft Customer Satisfaction Campaign P33 (Ignition Cylinder Protector). Hyundai launched this program to fix a massive vehicle theft vulnerability, but they have failed to release or distribute the physical parts to dealerships. I have been blocked from receiving this security fix since the campaign's rollout, leaving my car exposed to theft. I spoke today 10/15/26, with Piazza Hyundai in West Chester PA, to schedule appt, and was told this recall was launched in 12/25, and as of today, Hyundai still has not provided the parts. The P33 letter mandates that I repair the car by March 31,2027. BUT THERE ARE NO PARTS!”
