NHTSA Complaint #11438071 — 2016 HYUNDAI SANTA FE

Check engine light went on in 4/2021. Brought to local mechanic and states that it is an evaporator issue. Claims I didn't close gas cap tight enough. He reset code, closes gas cap and no check engine light. I bring it back after filling up my tank again tells me that it is because I don't close it tight enough. I oil change in 4/2021 and ask to check the code again. He claims may be a small leak and that I can drive it. I bring it back in late June early July for another oil change and light is on again. He claims small leak and it is fine to drive. I pick it up and he has car for a week to do oil change in Sept and to double check the check engine light and he says he fixed it with a new sensor for the evaporator. Light goes back on two days later. Take it to another mechanic who replaces his work and claims not good electric work. Another day of driving and check engine light is on. Bring it back to mechanic states no oil and that he puts 4.5 cans of oil into car and that the engine needs to be replaced. I am meticulous with cars. I ALWAYS get my oil changed every 3-5K miles. There is no way that I drove this car too hard or didn't have an oil leak. I park in the same spot at home and work every day - no leaks. It did not blow oil either. Please advise.
