SERVICE BRAKES
Noticed that there was a recall on this vehicle NHTSA Campaign Number: 19V645000. My concern is that I took my vehicle in back in 2018/2019 for this repair. However my vehicle vacuum pump completely failed the other day where I cannot brake. My vehicle is only at 70,800 and fail to see that if a proper repair was completed back in 2018/2019 for it to fail again a couple of years later with low mileage. While I was able to get this vehicle home safely my concern is that if it failed earlier in the day on the highway I may have cause a serious incident.

POWER TRAIN
Transmission Control Module TCM failed while driving down the freeway I84 in Boise Idaho. AC Delco part number 24256861. This caused the truck to go into limp mode when at highway speed. While in limp mode the truck would not respond to throttle commands. Truck slowed to 20mph causing a disruption in traffic flow and making it very difficult to get off the freeway, dodging traffic. The TCM failure has been confirmed through a local GMC dealer (Dennis Dillon in Boise Idaho). The Manufacture (General Motors) has discontinued manufacturing this part leaving my vehicle and thousands of others failed. GM's responce is the part is on a national backorder. 24-26 months at the earliest. Aftermarket support is none existent. There were no warning lamps or messages or symptoms prior to the failure. Very limited parts are available on Ebay (10 or less) . Dealer price for the TCM is $710. Ebay pricing is 4-10 thousand. GM customer assistance provides no answers and fails to ackowledge the safety concern of the failed transmission controller.

STRUCTURE:BODY
This truck has a 5 star crash rating, but is rusting very badly due to a defect in the design of the truck. There are tracks in the roof that lead down behind the cab. The water rolls down and then there is an indentation that holds the water. This water holding creates rust, horrible rust. The rockers, frame and the fuel pump rusted badly due to this defect. The 5 star crash rating comes into huge doubt due to such rust from the design defect.

STEERING
In the process of making a right turn my power steering suddenly quit working causing my vehicle to cross over into oncoming traffic. There was an eighteen wheeler that had to make a lane change to avoid a collision. At this time I had a warning light come on stating a problem with the power steering. I was able to slowly drive the vehicle to a local repair shop. The shop had to reprogram the steering module. I know my model had a safety recall for that very issue and I had it repaired at a GMC dealer in 2017. Apparently the problem still exists and I called GMC Corporate and was told that my vehicle had been repaired and was to old for any assistance. I now have no confidence in my vehicle knowing that this problem could occur at any time.
