Air bag light comes on making it unclear if occupants are protected or if air bag will just go off on its own. Problem is wires in back door jamb become fatigued and break causing failure of air bags. Vehicle is also considered an inspection failure as well in Massachusetts.

The contact owns a 2005 Chevrolet Colorado. The contact stated that the power steering fluid was leaking. The vehicle was taken to an independent mechanic who noticed that the frame was corroded through and was fractured between the bed and cab. The vehicle was repaired. The contact called spritzer Chevrolet amherst (200 N leavitt rd, amherst, oh 44001, (440) 703-6350) and was referred to the manufacturer. The manufacturer was made aware of the failure and did not assist. The failure mileage was approximately 91,000.

My vehicle failed state inspection due to excessive rust resulting in holes in the frame cross member. The rust and holes compromised the vehicle so badly that it could have easily broken apart and cause catastrophic loss of control. I think that the frames for some Colorado were manufactured with steel that was not up to specification, more precisely the steels chemical content was incorrect. This caused the frame to deteriorate to the point of catastrophic failure. From what I gleaned from the internet model years 2004,2005, and 2006 were affected by this defect.

Driving on expressway at 65 mph. Truck seemed to lock up parking brake and began to swerve. Car behind me tried to avoid hitting me and swerved into other lane, barely missing a collision himself. Nursed truck home. Took to my mechanic and explained what happened. In the parking lot of service center he crawled under to check parking brake cable and immediately noticed my frame had broken on both sides! this truck, seriously, is in show room condition. Mechanic checked rocker panels, fenders, under bed and floorboards and said there is no rust anywhere except on your frame. I baby this truck as I am 71, retired, on pension and social security and vet. This car is washed at least once a week and in the winter it gets washed twice a week. It has been waxed eleven time in the past year, August of 2017 thru September of 2018. Manufactures recommended services are all up to date or even exceeded. Internet shows this as a complaint with many 2004 - 2006 Colorado having rusted out frames and GMC is not willing to do anything about it. They should learn from Toyota how they took care of their customers with rusted out frames. This is a serious safety hazard. When these frames break as min did it slows down quickly and will swerve. I think the slow down is caused probably with the twisting of the body or the bed and possible strain on the differential or axle. Just a guess. Luckily, the car behind me was able to swerve out of my way, but just about hit a person in the lane he swerved into.this truck is garage kept and I only average about 4000 to 5,000 mile a year. And seriously this truck looks like it came off the show room floor.

Paint on front bumper is bubbling. It will probably need to be repainted. My guess is the bumper was not primed properly before painting.

I have owned my 2005 Chevrolet Colorado 4 door 4X4 since Nov. 2004 I have had tires that puckered, 3 radios installed, blower motor switch replaced 1 time and is now out again, a leak in the fire wall that has been in 2 times to be fixed and still leaks in hard rains, a defective brake light switch. And the worst gas mileage of any vehicle I have owned in the past 30 years. My 71 Monte Carlo with a 400 big block and 3:73 rear end gears got better gas mileage. Chevrolet said to wait till it had about 10,000 miles well it has 52,000 and still can't get past 16.5 mpg. And only 11 if towing anything. The radio has been fixed and the brake switch replaced I still have leaking fire wall and very poor gas mileage. I drive a nice straight shot 71 miles one way with only 2 stop signs between start and finish of my drive each day for a total of 140 miles of pure open interstate driving in a rural area! shame on you Chevrolet!

There is an undiscovered leak that is coming through the right side of the vehicle, which is soaking up the seat belt and seat due to corrosion. This could prevent the seat belt or seat from working and providing proper safety to the passenger. Manufacturer has been contacted by consumer.
