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. That melted the wiring harnesses to and from the battery, as well as being the cause of the battery boiling. The key issue is that General Motors would build a vehicle where the upper control arm is so flimsy it would break. I have read other incidents of the same thing with the Chevrolet Blazer where, for example, a person was going 30mph, the car flipped, and the person was knocked unconscious. A repeated corporate failure of this nature should have consequences.

I bought the 2000 Blazer used just over a year ago and have had nothing but problems. To begin, I replaced the alternator, fuel pump, and virtually all suspension components in the front end with just over 65,000 miles. On vacation during one of the hottest days of the year traveling home the Blazer over heated and left my family and I stranded on a major interstate with no A/C for nearly an hour before getting towed to the worst Chevrolet dealer in the country(richmond, va). We were forced to pay for a new radiator and miscellaneous parts totaling over $600. They said the coolant system was full of rust and the radiator was plugged and could not be reused. Now I'm experiencing the service engine soon that will not go out. After numerous trips to the dealer that started with leaking oil cooler lines, they said that the crank sensor was going bad. I replaced it, still the light stays on. Next they say there is a misfire in cylinder 2, I replace the plugs, wires, rotor, and cap. Still the light stays on. All of these repairs within the first 14 months of owning this junk and it is not anywhere near being paid for. GM needs to fix these problems. I have spoke with other Blazer owners and they too have experienced nothing but trouble. And the big 3 wonder why they are losing customers and market share. Have they ever heard of quality? looks like I'm going foreign.

Ball joints upper and lower replaced at 40K and 100K miles. Will be needing to be replaced again very soon at 140K miles. The replacement at 40K was a total failure of passenger side ball joints to wit: Vehicle was incapacitated as wheel was left 'bent'. fuel gauge fluctuated wildly if less than 1/3 tank of gas. Fuel pump failed.

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. Blazer, 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" I called Chevy's customer service line and they verified the document. They told me to take it to another dealer for a second opinion after that I guess I'm out of luck. My dealer found the document at the following url: service.GM.com/servlets/blobshtml"shtmlfile=1381844.
