   I was driving down the highway and all at once a bunch of different lights and emergency warnings started flashing on my dashboard and my car was almost like sputtering like it wasn’t getting the gas it needed or something. You could feel lots of movement right up front and I was forced to pull over and get towed. They said the engine would need to be completely replaced.

Also, I get an oil change at George Ballas GMC on [XXX] and 3 weeks later truck says change oil soon. AND YES THEY RESET THE OIL LIGHT AND I DROVE IT FOR 3 WEEKS…
