NHTSA Complaint #11542480 — 2017 HYUNDAI TUCSON

6 Mar 2023 check engine light comes on. Took to my mechanic (they were closest to me) to put on machine to find out what the problem was; they state that it was the knock sensor and said to take it to the dealership and also let them know that it was down one quart of oil since the last oil change Jan 2023). Dealership took possession of vehicle on 8 March 23. Didn't begin repairs until 5 Apr. Then they state there was still noise from engine and found scoring on the cylinder walls and may be why it's consuming oil. Then they wanted oil change records. Finally, after providing records, "Hyundai approved replacement of engine". Legal battle ensued because they were charging for parts (lifters) that were no longer on my vehicle. Ended up having to pay for the full invoice after bullying and terroristic tactics only to have the check engine light come on again (picked up the evening of 15 Aug 23, CEL came on at 06:00 on 18 Aug 23). Eminent engine failure, limp mode and/or fire potential make me afraid to keep my vehicle but financially, I must keep it a while longer.
