One problem related to interior rearview mirror has been reported for the 2002 Chevrolet Silverado. The most recently reported issues are listed below.
The interior rearview mirror has a distortion problem. Only in the middle of the mirror is the view clear. But when the view is in the top part or bottom part of the mirror, the distortion takes place. The distortion is in the form of seeing double vision. The best way to notice this is at night when another vehicle is no closer than 100 feet behind you and you look at it through the interior rearview mirror. Put that vehicle's headlights at the top and at the bottom part of the mirror and you will see four headlights instead of two headlights. Even in the daytime, if you look closely at the vehicle behind you, you will see a double image of its roof via a faint line. I have replaced my mirror at the dealership, but the second one is even worse. I filed a complaint with gm quality customer service. I know of another 2002 chevy Silverado owner who also has the same problem. This problem probably exists on most of them. If you have any questions, please call me. I am willing to demonstrate my vehicle to you so you can see how serious a problem it is. Thank you!.
