I will never let these idiots touch my vehicle again. I took my 2014 Camry in for an oil change and a tire rotation. When I left, I drove for about 10 miles before hearing a ticking noise from my engine. I checked the oil and there was about one drop on the end of the dipstick. I called my wife and she brought me four quarts of oil. It took all four to get the oil to the top of the dipstick. But, the ticking is still there. I took the car back and the technician that worked on my vehicle said it was like that when it came in. I guess I'm SOL. I will NEVER let thesee shade tree idiots touch my car again.
