NHTSA Complaint #11525354 — 2017 KIA SORENTO

We had two issues develop. The first issue developed about 30k miles after purchasing it new. The car would accelerate unevenly and after long drives the car would lurch during acceleration after starting from a stop. The lurching would continue for a few days before disappearing. No tech could reproduce it. They tried multiple times to reset the software and found no other issues. After a normal fuel injection cleaning at 100k miles, the lurching eased, but still remained. The issue was never resolved. The second issue came up at 108k. We heard a strange noise from the front right of the car when accelerating, but no indicators. The next day the engine light starts flashing and the car is vibrating, so we take it to the dealer the next morning. The engine oil is extremely low and the engine needs to be replaced because 3 valves are miss firing!!!! We had an oil change at 100.8k. We were well within the time for another oil change...a change, not a complete refill!!! There was never an oil indicator light. The engine was clearly burning oil too quickly and the indicator was not warning correctly.
