Hyundai Sonata

The vehicle experiences a severe delayed start/extended crank condition before finally starting. This is caused by a loss of fuel pressure prime due to the defective fuel filter housing leaking internally, creating an unpredictable and unsafe vehicle operation hazard. The dealership is denying coverage under the 15-year/150,000-mile extended warranty (Campaign TXXS), claiming the issue is a standard fuel pump failure while completely ignoring that the integrated fuel filter housing defect…

The fuel tank assembly became pressurized with compressed air due top worn purge control system check valve. This caused the tank to deform and the deformation of the tank led to the fuel pump being pushed out and the back seat of the car was completely unattached and no longer secured. There was a strong presence of gas smell in the car as well. The check engine light came on and the car began to drive poorly. It was taken directly to a Hyundai dealership where it remains as of today. This…

My 2011 Hyundai Sonata with the 2.4L Theta II GDI engine developed an engine failure at 99,928 miles. On XXX Hyundai’s dealer (McFarland Hyundai, [XXX]) ran Hyundai’s T3G connecting-rod-bearing test, and the engine returned NO PASS. Hyundai’s own test recorded the oil level as full. This engine family is the subject of Hyundai’s connecting-rod-bearing safety campaigns and its extended engine warranty. Hyundai declined the repair (#XXX) as “exceptional maintenance neglect,” although the oil and…

Transmission problems began around 60,000 miles (but we didn’t know what it was) — jerking and hesitation, that worsened over time. We took the vehicle in (November 2025 ),at around 109,000 miles at which time they couldn’t find anything. I took it back in December and they recommended the spark plugs. We took the car back again in March at which time they recommended other little things. We took the vehicle back yet again on March 10 and told them to check the transmission. The dealership said…

Upon arriving home I noticed that the paint was missing from the back passenger side & when I left the parking lot before heading home there was no paint missing.

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…
