Front Air Bag Sensor Control Problems of GMC Sierra

I start my truck one nice summer day and my "service air bag" light came on, strange I thought, since my 2008 Sierra 1500 only has 57,xxx miles on it. . No accident, no prior issues, not even inclement weather when the light came on. Took it to the dealer to have it diagnosed. The diagnostic cost was $132. 93, and that was to just for plugging in the tech 2 scan tool and running the sir air bag diagnostic test. I was not thrilled about it. Problem turned out to be a failure of the front left air bag sensor. The dealer said "OH we have one in stock at out other location, we can get it shipped over, and it would cost $550 but we could have the truck back to you later this evening. " how does one of these just fail? if its due to corrosion shouldn't gm pick up the tab on that? this safety component is what senses impact then causes the airbag to actually deploy and this part just randomly fails? how is that acceptable for any manufacturer, if there is a corrosion issue, find a means to prevent further failures and cover the cost of replacement for those that do fail. For a GMC truck that uses the phrase "we are professional grade" as the backbone for their products, why would they use parts that fail so easily? since some of their trucks used to be be assembled in wisconsin, and their head quarters is in detroit, michigan, it's very hard to overlook the fact that these places are not kind to vehicles. So why is it that a very important safety system, the supplemental restraint system, a key component can fail so easily, and there is nothing being done to correct it?.

My vehicle air bag sensors have been diagnosed as faulty. The dealership indicated that both front air bag sensors are part of a known problem where the factory tightened the bolts too far making the sensors prone to crack and collect moisture. This moisture then freezes and the sensors need to be replaced. This repair is very costly at over $200 per sensor and both sensors need replaced. This doesn't include labor. This is definitely a safety issue and I don't know if the air bags will function properly if an accident were to happen. This seems to be an item that should be recalled.

Airbag service light and message appeared. Defective 15297468 sensor caused system failure. Part badly damaged by corrosion.

Both part numbers152974468 (front frame mounted crash sensors) failed within 2 weeks of each other on my 2008 GMC Sierra pickup truck. They are supposed to be hermetically sealed units but both show signs of water intrusion, corrosion and swelling. When these fail the sir system is shut off. I have photographs of the parts if you would wish to see them.

Tl - the contact owns a 2009 GMC Sierra 2500. The contact stated that the air bag warning lamp illuminated. The vehicle was taken to the dealer.

On sept. 28th about 1pm I was trveling on a dirt road when I approached some pot holes. The day was sunny and dry and I went to apply my brake but as I hit the brakes to slow down I hitthe first couple and my side impact air bags deployed. I took it into the dealer and they advised that the computer advised it was in a roll and deployed the side impact air bags and also they advised the computer sensed there was someone in the passegners seat when there wasn't so maybe the seat sensors a bit sensitive. It was evedent I wasn't in a roll and they refered me to gm customer service who took my infomration and sent a 3rd party I believe raytheon to do an inspection. I called gm yesterday and they advised they recieved the results and per thier engineers and the data they pulled they determined that the pot holes that I had hit (which were not large) were large enough to tell the computer that I had lost stability and to deploy the air bags. With that they determined that the systems were functioning properly and that they were not liable for any issues or costs. I had spoken with joe the supervisor and I had asked him that when I get this fixed am I to be leary of pot holes in the future that it might set them off again and he directly answered that that is a possibility that if the computer senses that the truck has lost stability that they will deploy again. Again he advised everything was functioning properly. At this point I have to get my truck fixed but I'm don't feel safe driving it as if this had happened at freeway speeds I could have lost control of the vehicle. I did see another safety review that I believe had a NHTSA review # 10205258 which appears just like my incident but that one for a 2007 GMC yukon. Gm advised that the repairs would cost $2700 and if it happened again I would again be liable for the cost even though in my mind it's a design or eng. Flaw.

The contact owns a 2000 GMC Sierra. While driving approximately 50 mph in dry conditions, the vehicle was involved in a crash. The air bags failed to deploy. The contact injured his right shoulder. The police arrived at the scene and filed a report. The vehicle was towed to the auto body shop for repairs. The contact called the manufacturer and they sent out an investigator to inspect the vehicle. The investigator could not determine why the air bags failed to deploy. The contact stated that the failure was identical to NHTSA campaign id number 02v178000 (air bags:frontal:sensor/control module). The current and failure mileages were 81,000. Updated 04/16/08.

Driver airbag did not work in a collision, driver injured, truck totalled. Some trucks with this make year and model did have a recall on the airbag system. We are the original owners of this vehicle and did not recieve a recall notice.

While driving 25-30 mph on a smooth dirt road both frontal airbags deployed. Consumer was able to pull over safely. GMC will replace airbags free of charge only if consumer will sign release. If it happens again, they will not be liable. Airbag sensor was sent to detroit, no problem found. Vehicle at dealer since incident.
