this is covered under csp11. the problem is my car is a 2017 and they only allow a warranty up to 120,000 miles mine is at 158000 and they will not fix the problem now even thought we just started having problems.

Engine running rough. Check Engine Light illumination. Difficulty starting or a no-start condition. Noticeable loss of power during acceleration Check engine light P0192

The car was jump start due to a bad battery it cold and the light was left on. Right after the jump start a check engine light can on. When I put the vehicle in drive to turn the steering wheel it violently snapped bad and broken one of my finger nail. I tried aging in disbelief it happened aging this shouldn't be happening it could've broke my fingers.
