Faults:

All 4 ball joints replaced at 40k miles.

Complete brake job at 45k miles.

Exhaust manifold replaced at 60k miles.

Replaced heater core at 60k miles.

Above was done under warranty.

Ball joints at 75k miles.

Complete brake job at 70k miles.

Idler arm at 105k miles.

Cruise broke at 60k miles.

There are many more things that I have not listed that went bad with the truck, that are listed in other comments.

Now at 109k miles, it needs ball joints, front and rear brakes, and the tranny is going bad.

Faults:

The Isuzu Rodeo we owned before was slowly dying and we needed another vehicle fast. I found a 2000 Blazer LS 4x4 with 117,000 miles on it and the price was good, so I went for it.

So far I have had to have the intake manifold gasket replaced for $675.00.

I had to flush out the heater core myself AFTER the entire cooling system had already been flushed.

The door hinge pins are shot, but I have no intention to replace them.

Replaced rear brake pads as soon as we bought it.

The CD player just started making a humming noise.

The power mirrors don't work.

Both rubber bump stops in the front need to be replaced.

We slid off the road and into the grass, so we need to get an alignment done, but they are telling me that it needs a new idler arm due to the slide. I had owned a 1990 Honda CRX in 2005 and I slid it off the road twice (raining and went around the turn too fast, those CRX's don't weigh anything) and it had nothing wrong with it. Not sure how a truck this big could receive front end damage like that from just sliding through the grass.

The rear end also wiggles just slightly once you get up to 65MPH, but I think that the camber/caster may be out of whack.

Both driver and passenger reclining handles were broken off when we bought the truck. I have been told that this is common.

The right turn signal blinks faster than the left sometimes, even though no bulbs are blown.

The interior lights don't turn on and off as they should.

The interior drivers door panel has five of the nine plastic pins popped out on it, and causes the window to jam sometimes.

General Comments:

So far with the exception of the intake manifold gasket, I haven't had to spend tons of money on this truck.

It has good acceleration and lots of power.

I will never buy another GM vehicle. This Blazer should not have these kinds of problems going wrong with such little mileage. I guess that's why the previous owner wanted to get rid of it. Wish I would have known, but now that I do I will never buy another one.

Faults:

This truck is piece of junk. Just 30,000 warranty.

At 1,600 miles, the A/C stopped working. (fixed for some miles. It failed again)

15,000 miles, fuel pump lost pressure. Truck lost power and finally broke down (replaced under warranty).

18,000 miles, alternator burnt (replaced under warranty).

30,000 miles, problems with brakes (never completely solved, warranty was over).

40,000 miles and on, check engine light turns on once or twice every week. Problem cannot be detected until today.

Luckily, I sold it last week. I lost lots of money on this vehicle. No more American "tanks". Go with Japanese or Korean, they are way more reliable and cheap to own.

General Comments:

The Blazer is just a gas guzzler, and it used to break down so often that I eventually drove it sporadically.

It's a heavy thirsty machine. That's all it is.

I did all the maintenance at the official dealer, bought original spare parts, but it just didn't work right.

Please do yourself a favor and stay away from GM.

I just kept it all these years trying to fix it to sell it without losing so much money. Finally I just gave it away at 1/6 the price I paid for it. It spent half of the time parked at home or at the dealer.

My happiest day was my first day without it.
