One problem related to wiper has been reported for the 2003 Chevrolet Avalanche. The most recently reported issues are listed below.
I am a new owner of a 2003 Avalanche, I was satisfied with my purchase but my soonroof falls under the appropriate serial numbers (6,000,000-6,300,000) recall states that it may be covered by the company webasto hollandia. Vehicle is fine to drive places but sunroof must be fixed for coming winter. It worries me as there's a slight danger of it causing a road hazard if it were to fall out.
