I purchased a 2010 Hyundai Sonata in February 2022 from the original owner. In July of this year, my engine failed due to the oil consumption defect found in many of Hyundai's engines produced at the Alabama factory. My oil and check engine light came on before it was time for my following oil change, despite making on-time synthetic oil changes during ownership. The vehicle hesitated and jerked on my commute to work, potentially causing harm to myself and other motorists. I went to take my vehicle to the mechanic on my lunch break. The car failed to turn over and has been inoperable ever since. I need my engine replaced at no charge. It's unconscionable that corporate would turn me away because the engine has 146k miles, which is nowhere near the industry standard 200k. Hyundai has inspected the vehicle and confirmed that an engine replacement is needed.

Recently at the Hyundai Dealership in Plantation, Florida I had them repair 2 RECALLS which were the LAMPLIGHT SWITCH & CROSSMEMBER. These RECALLS were not done correctly and caused my ESC Light to come on and my car shakes while driving. I never had these items before until they worked on my RECALLS. Now the Hyundai Dealer service is refusing to fix the damage they caused. I need help right away. The RECALL repair appointment was on June 12, 2022 and had them check the RECALLS again on August 29, 2022. My car is still at the Hyundai Service in Plantation, Florida.

Car has only 77,000 miles and was well maintained. On August 27, I had driven the car late afternoon, parked. Later after a couple of hours when I went to start it, it would not start, jump start did not work. Mechanic replaced the starter and still would not start. He checked the engine and told me that the engine has seized. I took it to the Hyundai dealer who confirmed that engine has seized. I contacted Hyundai as the complaint is similar to other car engines that seized when driven between 60,000 and 90,000 miles. Hyundai motors is not willing to fix this major issue.

Have seen the recall notice on Sonata 2011-12. I have a 2010, manufactured in Alabama. The motor went out in the car a few months ago while I was driving. It lost power and stopped. The car continues to sit in my driveway. I had the dealer inspect it before it went out because of a knocking noise. The dealer (mungenast Hyundai, 649 dunn rd., St. Louis, mo) reported it was a motor problem and the only way to fix it was to replace the motor. The warranty had already expired, and I did not have $5000 to replace the motor. The motor problems did not start with the 2011 models. I hope you can look into this, and hopefully I can get my vehicle repaired. Thank you.
