“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.”

I thought this was addressed and fixed on newer models. I'm told it'll cost me $1500 to fix. If they aren't going to make this good I'm switching over to toyotas.
