who do I file a compliant against Chevy for misdiagnois of car problem.

What is your question?

Chevy never tell people with Catayltic converter problem that is two on the Chevy Equinox, So you go to great length to find out what the problem is , I have replace o2 Sensors, Solenoids, and manifold. Chevy offer me $1300 to fix my car, help me qualified for $600 discount. If I had gone for this and found out later it could be another cataylic converter in the car, which chevy equinox has two. I believe Chevy is very much aware of the problems with the cataytlic converter problem. I am goung to justice for this issue,
