Selected complaints filed with NHTSA by 2000 Chevrolet Blazer owners, lightly cleaned up (personal details are redacted by NHTSA).
The handle that allows you to recline the seat broke off flushed with the seat, this happened to both the driver and passenger seats in June 2005. The hood will not pop up when the lever was pulled until one banged on the grill or the hood in certain spots, which just started in March of 2007. The gas mileage dropped from 20 mpg to 16 mpg within 6 months. The back glass stuck and was hard to open, started in 2006. When turning on the air conditioner (A/C ) the car had no power, I have to turn it off when accelerating on the interstate or on hills. If the cruise control was set it kicked off when the A/C was on. When I needed to stop quickly the brakes failed, and felt a grinding sensation through the pedal, but the mechanic changed the brakes and checked the rotors, but hasn't found any problem. Suspected a defect somewhere in the brake system\ as of 2005. …
The front bumper of my 2000 Chevrolet Blazer was completely crushed when I hit a sign pole in a parking lot. It was in my blind spot (where the front windshield meets the driver-side door, that strip of metal) when I pulled slightly forward and to the left to leave the lot. I could not have been going very fast, this pole was within 4' of my car, yet this approx 4" diameter metal pole completely crushed the bumper. This is unbelievable frailty in such an important part of the protection afforded a car's occupants. I'd like Chevy to replace the bumper. This is unacceptable to me. I will never purchase another Chevy. It's back to volvos for this woman.

I have a tailgate/hatchback combination. The latching mechanism has separated from the glass. The glass company that the dealership sent me to told me this was a manufacturer's defect and that new glass would have to be ordered. I went back to the dealership and they told me that it could be that, but also offered an implausable explanation for a scenario were separation from the glass might have occurred. They refuse to rectify the situation or even investigate it. The alternate scenario was offered by a regional dealer manufacturer who has never seen my car and who refused to inspect it personally when I requested it.
