I was driving to work when my oil light, brake light, and battery light illuminated on the dash board. I stopped and opened the hood to check oil and loose battery terminal but everything was okay. I tried starting the car but to no avail. My mechanic initially said a loose nut made the timing chain not to work well. He has retimed it but still car won't start. He now claims the valves are broken and need replacement.
My car has 10000 miles.
My car has an automatic transmission.
