   The Engine stalled completely at highway speeds. It was then towed to the dealership and was diagnosed with engine rod bearing failure. Hyundai is denying the warranty extension for this engine failure based on an incomplete 'Service Campaign 966' that does not appear on the NHTSA public recall database, leaving consumers unnotified of safety-critical software updates."

   My vehicle was brought to an authorized Hyundai dealership In November 2025 to complete safety recall campaign KSDS (Campaign 966). Soon after picking up the vehicle after the dealer flashed the ECU, the vehicle went into a permanent, dangerous "limp mode" that severely limits the engine's RPMs, making it impossible to accelerate to highway speeds. The vehicle's computer displays zero OBD-II diagnostic trouble codes (no P1326 or standard fault codes). The dealership is…

   After a Hyundai dealership installed the Knock Sensor Detection System (KSDS) update to prevent engine bearing failure and potential fires in certain Theta II, Nu, and Gamma engines, my Elantra GT is stuck in limp mode and will no longer accelerate. Since it takes my car a very long time to reach safe driving speeds, I took the car back to the dealership and they conveniently blamed the catalytic converter. I went for a ride with a California BAR associate, and he agreed…

   I bought a 2017 Hyundia Elantra GT on 2/14/22 for my 16 year old daughter cash $8000. The car ran good for about a month but I could smell fumes so I took the car to the dealership on 3/11/22. I had to replaced the catalytic converter with the Hyundia dealership, which cost me $2600. On 4/8/22, my 16 year old daughter was driving to work and she advised me that it was really hard to stop on the brakes. I asked her did the brake light or service light come on. She was like…

   Bought my vehicle used a few months ago. Engine started knocking. Hyundai dealership told me I had a engine recall but would not fix the problem due to sludge buildup causing the engine to knock. Sludge buildup is due to manufacturing problems but Hyundai is refusing to fix.

    I am the second owner of a 2017 Hyundai Elantra GT hatchback. I have not had any issues with the car until last week. I was driving in town to pick something up and the engine started knocking and losing power. The rpms would go up but I could not go anywhere. Eventually I had to park the car and have it towed to my house. I checked the oil and it was very low and had sludge in the upper engine area. I could visually see sludge where you fill the oil. I received no low oil…

    I was driving down the freeway and moved over to pass a slower vehicle when the engine lost acceleration. I pulled over to the side oft the road and had the vehicle towed to the nearest garage. They told me the engine lost all its oil and the engine needed to be replaced. I find this hard to believe in a 4 year old car. I am bringing it to dealership tomorrow to see if they have the same diagnosis.
