2010 Hyundai Sonata Engine Problems

While driving 60–70 mph on [XXX] just north of Sylmar, I suddenly heard a loud, deep “pop” from the lower part of the car. Within seconds, the engine began steaming heavily and leaking oil everywhere. I immediately turned on my hazard lights and began maneuvering toward the right shoulder, crossing multiple lanes with semis and fast-moving traffic approaching behind me. I felt unsafe and feared the car could catch fire or explode, especially with smoke and oil present. After safely exiting the vehicle, a mechanic later told me the rod bearing blew and punched a hole through the bottom of the engine block, calling it a total engine failure. He said it would require a full replacement and matched known issues with this model. There was no warning before the failure. I’m having it inspected at Hyundai of Downtown Los Angeles on July 28. I believe this event posed a serious safety hazard to me and others on the road. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

THE NEXT DAY THE CAR WOULDN'T START AGAIN, WHEN WE REALIZED IT WAS THEN THE STARTER. I PURCHASED AND INSTALLED A NEW STARTER ON THE VEHICLE ($105 ONLINE) ISSUE RESOLVED.
