check engine light, bad knock sensor
I can't believe I bought a brand new vehicle and the engine was replaced at 5 months of ownership

Could not believe the light came on again. Engine ticking like there was low oil

This problem has existed for 70k miles . All 3 lights come on and then car holds back. Chevy refused to ever cover it or figured out the problem. It is amazing there has not been a recall on this?
