2001 Chevrolet Blazer Owner Comments

problem #8

Blazer 6-cyl

  • miles


Any time I am driving my fuel gauge goes crazy. I never know how much fuel I actually have because it constantly goes up and down. I've ran out of gas a few times because it shows I have 1/4 tank or more and then it'll just go down all the way, then shoot up 3/4 tank and so on. When I'm coming to a stop, especially in small downhills, my brake pedal starts vibrating and barely slows down. I get nervous all the time because I'm afraid my car will not stop. It also does this if I'm starting to brake, and one of the wheels hits a small bump in the road, then it's almost impossible to brake normally because the brake pedal starts vibrating, the ABS brakes light comes on, and my car will not slow down which is very scary especially if I have my 3 year old in the car.

Fuel gauge fluctuates between empty and 1/3 full without warning. This happens in park and when driving. You never know how much gas you have. I have seen it drop form 1/4 full to completely empty in seconds. I have run out of gas on way to work when gas gauge said 1/4 full when I started off to work, only a couple of miles away. I have told local Chevy dealer ( H & H ) about problem when having service but they said that was not a problem, was probably because you were on a slope. This has been an ongoing problem since I originally purchased SUV new.

Fuel gauge jumps from full to empty all the time regardless how much fuel is in the tank - making the gauge useless for displaying the amount of gas in the tank (same thing happens on wife's 2002 Blazer).

For the past six months, I have been experiencing problems with my gas gauge. The gas gauge will show 1/2 tank of gas and within minutes the low indicator light will turn on. Other times the fuel indicator will fluctuate from full to empty.

The events that lead up to the failure of the fuel injection system equipped on my 2001 Chevrolet Blazer are in correlation to the manufacturers knowledge of having installed a defective product on 1996 - 2002 vehicles with sequential central port injection. After having to deal with the problem of figuring out how to fix the code P0300( random cylinder misfire) on my 01 Blazer, I realized it was time to get more help from outside sources who have experienced similar issues with their vehicles. I've done enough research to know now that after eight years of owning the truck and dumping money into unnecessary repairs that Chevrolet should fix this problem at their cost since they knew about it after being investigated by the California epa research division on air pollution back in 2003. They found the scpi system installed on models between 1996 and 2002 to be faulty creating a problem with the start up of many SUVS which lead to emissions failure. I'm researching this now because I've finally connected the dots and realize that Chevrolet knew about this problem many years ago and they cut a deal with the epa to extend the warranty coverage on such vehicles for 10 years or 200K miles in an attempt to satisfy California regulations. Well, what about the rest of the United States and how we deal with air pollution. I thought GM and Chevrolet wanted to be the company that would set the example in "going green" for our planet. It doesn't make sense until you realize the amount of money that they save by not having to replace faulty fuel systems on older model vehicles which happen to be driven by people who are a lot smarter than they think. I've taken the Liberty of filing my claim with Chevy to resolve this issue. I'm hoping that this complaint along with valuable information on the internet as well as your web site can inform others of their rights and how we should all be covered under warranty to fix the problem permanently. Thank you for your time.

Car would not roll over. Mechanic told us that if it was a a fuel pump problem that it would eventually get worse. Turns out it was not a fuel pump, but the fuel pressure regulator that had to be replaced. Total bill of $381.
