NHTSA Complaint #11565550 — 2017 HYUNDAI SONATA

2017 Hyundai Sonata with 108,600 miles, has experienced oil consumption/burning, since at least 85k miles. Costs outside of manufacturers recommendation: *Oil consumption report ($85) *Extensive engine cleaning ($500) -Hyundai considers 1 quart consumed per 1000 miles, acceptable. *Rod bearing clearance test ($140) **Engine replacement (reason for complaint, will cost $3880) Hyundai dealership most recently stickered oil change at 3,800 miles. At approximately 3,000 miles, the oil pressure light began to flash on/off. I checked the oil, it was low. I called the dealership to ask for advice. They indicated my car was OK to drive to the dealership (40 miles away), for service. On the way to the dealership, on the highway, my vehicle started to experience intense vibrations. My check engine light came on. I had to take my car from ~65 mph down to about 40 mph in a very short time, trying to maneuver in between semi-trucks, going from the left lane to the right shoulder. This was not safe, my engine could have seized. After this, my engine emits a loud knocking sound. Once I arrived, the dealership recorded 2 quarts of oil in the engine. After the oil change, the knocking sound still remained. They indicated they would not recommend driving the vehicle until they investigated the knocking sound. They performed the rod-bearing clearance test, and indicated it passed. With the knocking sound, their recommendation is to not drive the vehicle, and to replace the engine, ($3880 with many reductions in price). They've indicated Hyundai corporate would decline to replace the engine because the tests are not favorable for replacement. I've submitted an escalated case to Hyundai (HMA), to look into this. In short, they have declined to do anything because my VIN, year/model, do not qualify for any extended warranties, or recalls, to require anything to be done. The vehicle is not safe to drive. I've done all maintenance, and am left to suffer.
