NHTSA Complaint #11642049 — 2017 HYUNDAI SANTA FE

In October I took my car to dealership for an oil consumption test and I was going through 10-15 quarts of oils between oil changes. In 322 miles I used 2 quarts of oil.Replace the engine is what I was told and manufacturer denied all goodwill. I ride around with a 5qt jug of oil and funnel in my car at all times. 10 days I was driving down the highway with my husband and child with the cruise control on, when I noticed that my tactometer was continuing to increase and the engine reving for no reason. I shut the cruise control off and the car speed slowed immediately, and when apply my foot to the gas I was not gaining any speed only slowing down. I pulled over into the break down lane and put the car in park. Once I put the car into park, it started to idle very loud and hard with the check engine, oil pressure and battery lights coming on and stalled, would not start. Had towed to personal mechanic he recommended taking it to the dealership as he was coming up with no pressure in the 4th cylinder and the 3rd at about 50%, checked with boarscope for faulty valves and saw nothing. Towed to dealership they say valve was consumed thru the engine it runs fine but not because engine needs to be replaced.
