Certain sport utility vehicles equipped with 4 -wheel drive fail to comply with the requirements of federal motor vehicle safety standard no. 101, no. 110, no. 114, no. 225, no. 209, & no. 208. Vechicles were built with a left -front brake pipe with a circumferential score at a random location along the lenght of the pipe as the result of the manufacturing process. If the brake pipe partially or fully fractured,brake pedal travel would immediately increase and front brake performance would be reduced under certain circumstances the front lower control arm brackets may fracture. Missing welds on the rear flow plan the calibration of the transfer case control module could cause insufficient high speed gear engagement. This fracture could result in separation of the front lower control arm from the frame some of these vehicles were built with a range shift collar in the transmission transfer case that contains cracks.

I was pulling away from a stop sign when my vehicle just shut off. I pressed the brake, put my vehicle in park, and turned the key to the off position. Then I started my vehicle as I normally would, and it started up without a problem. This was very disconcerting and scary. This happened in a quiet, residential area, so there was no other traffic on the road at the time. I intended to have my vehicle checked, but I never did. This was several years ago. The incident was brought back to my attention because of a recent but different mechanical failure with my vehicle. During my internet research of the other mechanical problem, I came across recall information for other gm vehicles that had been recalled for suddenly shutting off while in drive. Although I did not find recall information for my make/model/year, I am filing this report because my vehicle has shut off while it was in drive. Since I don't know the exact date when this occurred, I will place an approximate date in this report. I was "house shopping" at the time, so the approximate date will be close.

I started my vehicle and shifted into reverse. The shifter handle moved freely but would not engage in reverse or drive. My vehicle was stuck in park. Luckily, this happened when I was in my garage at lunchtime headed back to work. When I searched on the internet about what the problem could be, I saw that other gm vehicles had been recalled for a broken shifter cable. When I spoke to the tow truck driver and explained my problem, he said that it was probably a broken shifter cable and that he had towed other trailblazers for the same problem and that the vehicles had been part of a recall years ago. I had not found a recall for my particular vehicle, but that other gm vehicles had been recalled for that reason is why I am filing this report. I have had my vehicle repaired and will upload the repair invoice.

When I turn 4wd on, the light gets stuck in 4wd even when I try to turn it off. I think my car is stuck in 4wd at this point.
