4 Warning Light On problem of the 2008 GMC Sierra

Failure Date: 08/23/2013

Warning light came on about air bag, took to GMC dealer as GMC had no recall on this warning GMC dealer ran test determined the passenger air bag sensor had corroded and I had to replace it and it was not cov by warranty, so pd 317. 00 to have replaced. Something this important in the vehicle should have been recalled and sensor moved to other location as it was corroded from weather? GMC dealer told me 2 things could happen if I didn't get it fixed, could go off randomly or would not deploy if in accident therefore both of which could have caused fatality if happened in operation. Would like complaint filed as I will not get my money back, but GMC needs to be aware of this in this year truck. Maybe save some lives if it is recalled and moved to where weather cant get to it. GMC customer service was of no help in getting this replaced or even a report made of this incident, I had this replaced in oct. 2013 and was terrified everyday driving it that it would go off, and cause me an accident, and dealer advised me that I had 2 of these bags, so at least they (sensor) did not go bad at the same time. . . This was a lot of money to me to have this fixed plus the 39. 00 to have them run computer test on it. Needs to prob be a recall on this part, and relocation of where the sensors are. Thanks.
