Took my car in because it smelled like burning oil when I drove. After 6 hours in the shop they told me it was leaking a bunch of different places and that my oil cooler was not covered under powertrain warranty. Took it to a 2nd opinion on Friday. Got the right estimate and what was wrong with it. Researched and found out the Engine oil cooler is covered under power train warranty. Took it back that following Monday and spoke with Josh the manager. He did looked it up himself on the computer and it ended up being covered. Got my money reimbursed for the diagnostic test they charged me for. Picked up my car, It would get up to 40 mph headed back home on the street and was making a loud whistling noise. Took it back to the mechanic, they said they forgot to reset some sort of sensor. Which fixed the oil smell. Car still makes a whistle noise like theres another air leak or something when I step on the gas. Horrible customer service by Yessenia. She was extremely rude. Now I have to wait until I'm off for Christmas break to take it back to the dealership because I've already taken too much time off. I'll never buy a chevy again. Worst car ever. 2014 chevy cruze LT.
