Blazer 4WD 6-cyl

  • Automatic transmission
  • miles


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.

I purchased my 2000 Blazer in 6/20/02 from a Chevy dealer in pa. I purchased the extended warranty. I have until 6/07 OR100000 miles I have replaced the coil and distributor cap and rotor 5 times a new fuel pump a catalytic converter windshield washer motor and turn signal switch it has gotten to the point that I can't even sell it to anyone private and I can't afford to keep it. There has been electrical and computer issues shorts that melted the fuse box under the hood that melted the relay for the fuel pump. Also there was a short that wiped the computer codes out and I had a rough time passing emission testing I am at the point the extended warranty does not want to spend any more on the vehicle. I have had the motor mounts replaced twice in 4 years. I have never been notified of any recalls orservice notices. I have had the vehicle serviced by licensed mechanics and had it serviced at the appropriate mileage required for the warranty.

I have purchased a 2000 chervolet Blazer, I have a faulty fuel pump gauge, one that will never tell you the right amount of gas. This lead me into running out of gas at a very uncivilized area, and it could have ended up being a wreck, if a emergency lane wasn't available. A few weeks later I learned that a entire fuel pump was needed to correct the problem. I researched this on the internet and from talked to other people with Blazer: They all have the same issues, gas problems, and I believe Chevy is in fault here for producing a faulty fuel pump to thousands of owners. This part costs $400 to replace.

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.

2000 Chevy Blazer 4.3L V6 76K miles 2 door the sending unit on the fuel pump has gone bad and is causing my gas gauge to give an incorrect reading. I must now use the trip odometer to guess when to put gas in my truck. From research I've done this a very common problem with Blazer of this year. GM should offer a recall for this $600+ job also replaced the upper & lower ball joints, idler arm and both wheel bearings in the past month. Seat recline lever on passenger side has also snapped off and rear washer fluid sprayer no long works. I've owned 4 other Chevy/GMC vehicles and had to replace the fuel pump in 3 of them. I will very much consider these issues and how GM handles this most recent one when I go to buy a new truck next year.

Sending unit/fuel pump broke so my gas gauge doesn't work properly. Gas gauge works from full to half a tank of fuel. From half to empty the gauge doesn't move. I just want to see if others are having the same problems. Running out of gas could be dangerous.

2000 Blazer started surging. After several months of surging, one day car would not accelerate on highway and a few minutes later it stalled. It restarted but after several blocks, it stalled again. This kept happening. Car was towed by aaa 67 miles to my dealer. Dealer could not find anything wrong but thinks it is probably the fuel pump. Car is still surging. After 1.5 months car stalled again while idling in a line of cars. It restarted after some difficulty. I then took it to another Chevrolet dealer. Again they couldn't find a problem. Said they couldn't do anything until something showed up on the computer or car completely dies and won't restart. So I don't feel safe driving the car since I don't know when it might shut down on me in a dangerous situation.

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. I am paying $14,000 plus for a 2000 Chevrolet Blazer with a faulty fuel pump.the door entry will not properly take in the key to open the door.the gauge meters were dancing back and forth and not properly reading the was a rental car before I bought it so I had no real history of recalls or mechanical reports.
