Filed Jan 30, 2026 · Airbags · CT

The front impact sensor, also known as a crash sensor (part # 10370150), is no longer functional. It detects rapid vehicle deceleration during a frontal collision and sends an immediate signal to the Airbag Control Unit (ACU) to deploy airbags. Located behind the front bumper or on the radiator support, these sensors measure impact severity to ensure airbags deploy only when necessary. This part is no longer available from GM or any other aftermarket distributor. It is a critical part for any occupants in a crash. I am just one of many people who cannot make safety corrections.

I went out to my truck in the morning and my dash board indicator told me to get my brakes checked; everything was fine the night before. I brought the truck into mymechanic and found out that my brake line is corroded and broken. Also found out that this a recurring and consistent problem with the gmc sierras. I have my truck serviced by an authorized service center on a regular basis and this has never been mentioned to me. This needs to be a recall item! Serious safety threat. Cannot imagine what could have happened if this occurred 2 days later when I was pulling our 40 foot rv. Shouldn't gm be responsible for this? My truck is now in the shop getting the brake line replaced.

I was driving down the road when the steering wheel locked into place. I had to jerk it hard in order to get it to released from the locked position. This has happened twice already. Can easily cause a crash. Needs to be fixed by manufacturer.

On march 8,2010 I took my car that I bought 2 years ago to an official emissions inspection station; the vehicle failed. At this time I was given a set of recall papers 09014 special coverage adjustment engine control module- emission related reprogramming that explained what the problem was. In the mean time I took the car to gm . They told me it would cost $125 to diagnose the problem by the time they were done I had a bill for $280 and told it would cost over $1000to fix the car so that could pass (they need to replace the steering column to receive communication I see there is a recall on that) I want to state that I showed the workers at gm the papers showing what the problem was but I was told that was not the problem and they then told me if I want it fixed I would have to pay for it.this occurred after I signed a paper allowing them to "look" at the car . I need someone in authority to help me find out this problem should have been taken care of by gm and whether or not the action of gm was fraudulent. Thank you took the vehicle inspection to the state of connecticut on 3/19/2010 and it pass inspection.
