Are there Any owners of 2002 Z-28's that got the letter from GM stating that the left or right Cat or both "may" fail? If so did your SES (service engine soon) light come on and did your local GM dealer charge you for the initial diagnostic charge? And if they did charge you were you reinbursed the intial diagnostic charge under the warrenty letter GM sent you? I would appreciate any help on this as my cat(s) are making the SES light come on. Thanks!

 

Emission equipment should still be under warranty so get it fixed.
