I have a 2004 GMC Yukon denali. It has 56,000 miles. The service air bag light came on and I took it to dealership. They told me it was $50 to scan system and $580 to fix the passenger air bag sensor. The old part is still on my car beacuse I am not paying that for a $25. 00 part. I think this is rediculous. No wonder people are going foreign and getting 10 years/100k mile warranty.
