Fortunately, I had just gotten off the freeway and was looking for an address at a slow speed. All of a sudden the car lurched; I had no steering; I lost all electrical control; the car ground to a halt; smoke came out from under the hood. I and a friend got out of the car. Fortuitously, fire trucks appeared. It turned out they were returning from another incident as I could not believe the immediacy of their response. They took over preventing further aggravation of this situation. The battery was boiling. All the electrical wire harnesses were melted. The upper suspension control arm was broken. The firemen's observation was, if I had been going any faster, the car could have flipped. After being towed to a nearby mechanic, I learned the upper control arm had broken. It impailed the starter which shorted. …

I have a 2000 Blazer lt 4wd with 44,000 miles on it. I recently started experiencing vibrations at highway speeds. My dealer verified the problem. According to a GM document, there is no fix to this problem. According to GM document id# 1381844. The document is entitled "vibration at highway speeds-suspension wheel #pi01273b - (09/15/2003). The document explains the problem & symptoms exactly as described in many of these discussions. There is a line in this document that reads: this vibration is considered a normal characteristic for these vehicles and no repair attempts should be made." this document covers 2 & 4wd drive GM vehicles with the same body types (I.e. Blazers, jimmy, bravada, s-10, envoy) and covers years 00 - 03. This vehicle is unsafe for use on the highway!! If this was "normal" why didn't the vehicle do this when it was new? …
The fuel pump,line and tank are faulty at 35000 miles. I bought it as a used car from santa ana Hyundai who agreed to fix the fuel pump but did not. The transmission is not changing gears properly, it would not start when I turned it off to get gas on 9-26-03, the left front end is popping with a loud noise,the brakes are not antilock brakes,it feels as if I am hitting metal when I stop hard,the panel lights would flicker, lights on dash board when flash when I had seatbelt on. I had a Chevrolet dealership fix the minor things. The battery cable was loose and they oiled the joints to stop the squeak. The dealer refused to fix the fuel pump which is unsafe and demand I pay him money that is already above the price of this car. …
Urgent- this will kill people please read - my 2000 Chevrolet Blazer rolled at 30 MPH after hitting a chuck hole on the right side of the road. It threw me to the right side of the road so I brought the vehicle back onto the road at which time my steering column was going crazy and then I rolled at least once before stopping - I really thought I was dead, and my vehicle is a total loss. I have the vehicle in my possession now - because of theft related issues with allstate insurance company. I would like some help showing the world that it May not be a Firestone problem, it May be a suspension problem. I can close my eyes and tell you in slow motion exactly what the vehicle did and you would think GM would want to have me interviewed -- since I lived!!! I have pictures as well if you want to have them emailed. Please help. …
My Blazer now has 56,000 miles on it. I have discovered that it is in need of front end repair - specifically the ball joints are badly worn, the boots on the frond axle have a bad crack on the right side, and there is significant idler wear. In doing research, I have discovered that numerous Blazer owners have experienced similar problems. I feel this is a design defect. I have also had two other issues that I am now discovering are common problems with a great number of blazers. Both front reclining seat handles have broken off. I am also experiencing problems with the doors seeming to not align properly - as if the welds or hinges are failing. These have also been mentioned repeatedly in your complain area for this model. I have not gotten these items repaired as of this date. The Blazer is now parked until I can afford to get it fixed.
Upon approaching the driveway vehicle suddenly made a noise. Steering wheel felt funny. Also, front left tire turned in the opposite direction that vehicle was going. When this occurred vehicle skidded. Consumer depressed the brake pedal to stop. This occurred because the left front lower ball joint came apart, and the front right ball joints were starting to show signs of the same failure. The entire front suspension assembly needed to be replaced. Also, automatic transmission slipped when shifting from first to second gear. Meanwhile, while driving in over drive mode, the over drive disengaged and vehicle speed was reduced from a rapid pace to a very low speed. This failure almost resulted in an accident. Dealership determined this was caused by a failure in the torque converter solenoid.
I am complaining about the front wheel bearing on a 2000 Blazer with only 36,754 miles on it. These are sealed bearings and no way to service them, they are suppose to last the life of the vehicle. The vehicle vibrates and makes noise and is ruining my tires and could make the vehicle wheel fall off. I got the vehicle used but have only put 10,000 miles on it in 2 years and I have the vehicle serviced every 3,000 miles and have all the records. I feel that there must be a problem with the bearings for them to go in 36,000 miles if that is considered the life of the vehicle maybe I should start buying fords.
While driving 25 MPH the transmission failed. The dealer was notified about 7 months ago but they could not duplicate or correct the problem. The dealer was notified of the shruddering and slippage of the transmission at 23863. The front differential pinion seal leaked, the check light was replaced due to the malfunctioning switch, the brake light had become inoperative due to an open circuit, the heating seat was inoperative, there was a rattle in right front suspension, the transmission had no reverse, and there was hard shifting into the forward gears.
