I have a 2006 SV6 with 50,000 km on it and I have had to take the van in twice to have the passanger side door fixed. Both times the door stopped working I tried using the manual setting. Well I managed to get the door closed but the ding ding ding would not stop. Only solution at the time Crank up the tunes. Both times GM has been great and fixed the problem under warranty but I am worried about what happens after the warranty runs out. Has anybody else come across this.
