problem #25

May 082013

Blazer 6-cyl

  • 145,000 miles


Ever since I own this vehicle, the ignition switch does not lock. Therefore it is possible to leave the truck and not know the ignition switch is still in the on position. Also, the gas gauge bounces all over the place and I have to use the trip to know when I need gas. This has also been a problem since I own the truck. Occasionally, the low fuel light comes on (I know I have fuel) and the truck starts acting like it's low on gas.

TL- the contact owns a 2000 Chevrolet Blazer. While driving approximately 65 mph the contact noticed the fuel gauge reading fluctuating. The contact stated he was unable to know what the actual amount of fuel was in the vehicle. The vehicle was not taken to the dealer for diagnostics. The vehicle was not repaired. The VIN was not available. The approximate failure mileage was 70,000.

I just turned the 100,000 on 7/15/10 couldn't go anywhere cause it was in the shop being fixed... lemon so much for buying new.

Fuel gauge fluctuates wildly between full and empty when tank is less than half full. If you look it up the GMC jimmy which uses the same fuel system has the same customer complaints. You never know how much gas you have in the tank. This caused me to run out of gas on a interstate highway in the middle of rush hour and I was unable to pull over to the side because of traffic. Luckily no one ran into me, but it did create a bad traffic problem. GM refuses to admit this a problem but the mechanics I've talked to say this is a problem they have to repair all the time. This vehicle should be recalled before someone gets injured or killed.

Fuel gauge fluctuates violently and rapidly regardless of the amount of gas in tank. Problem has existed for over two years and appears to be a common defect with part. Attempt to replace however options are limited due to sending unit and fuel together as one unit.

I have a 2000 Blazer and I have been having problems with the fuel gauge for the last 6 months. It fluctuates between full & empty constantly. Once it hits a half tank, it stops keeping track of how much gas is in the tank. Haven't had it fixed yet. Seen too many complaints now, GM should replace for free.

  • 90,000 miles
At 90,000 miles my fuel gage became erratic, Chevy dealer says it's the fuel pump. At a cost of $800 to fix I'll calculate my mileage and live with out it. GM taking low bid on the fuel pump means I no longer buy GM products. Fix mine at no cost and you got me back.............maybe!

Blazer 4WD 6-cyl

  • Automatic transmission
  • 120,000 miles
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 fan kicked on all the time, even when the engine was cold, and in winter when first starting. One mechanic told me that in many Blazer the catalytic converter broke off in the muffler, which had to be replaced. Had been told this happened so much that most people left them off. Too many other problems to mentioned. Also, the horn worked only when it wanted to, problem in the steering wheel.

I own a 2000 Chevrolet Blazer, 4 dr. Lt model. The fuel gauge is erratic and will bounce all over the range, whenever the fuel level is at approx. 1/2 tank or less. This has caused me to run out of fuel, on the highway, because I thought that there was fuel in the vehicle; but the gauge was not registering correctly. The local dealer wants over $900 to fix this problem. In doing some online research, this appears to be a very common problem, and GM should issue a recall and fix this problem.

Blazer 4WD 6-cyl

  • Automatic transmission
  • 45,000 miles
I was driving to Texas over christmas and after I stopped in Colorado and got fuel by the time I reached wichita Kansas is when the fuel gauge started to stay at full when I knew it was almost empty. The gauge bounces around when it is in park or neutral. I travel a lot and it makes it very difficult to judge just how far I can drive before I have to refuel. No repairs have been made as of yet.

We purchased a brand new 2000 Chevrolet lt Blazer and now the fuel sender will not work properly. Therefore, we do not know how much gas we have in the tank. Per my brother's inquires on a website he found out that there have been numerous other people that have had this problem and was told by a GM technician that this was a defect in this make/model, they are aware of the problem. I think it should be a recall and the consumer should not have to pay to have this repaired since they know it is a defect and is costly to repair especially since the vehicle is not very old!

I have multiple complaints, the gas gauge on my vehicle stop working and I ran out of gas in the middle of the street when I realized problem 2 the rear brake lights and hazard lights do not work. The other problem is the vehicle stalls, and when it finally take off, the car jerks and the driver seat moves/slides back from the hinges which caused me to not be able to reach my breaks and run into a curb. Also the driver side door sticks and is difficult to open. Lastly the wheel baring and ball joints have gone bad twice and the car has less then 75000 miles on it. I called GM customer service department and explained all of my concerns and was told they we not aware of any nationwide problem and there was nothing they could do except fix the hazard light malfunction. I researched on the net and found many many people complaining of the same concerns I have.
