Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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.”
NHTSA complaint #10609204, filed 2014-07, 145,000 miles“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.”
NHTSA complaint #10231382, filed 2008-06, 120,000 miles“Fuel sensor problem that's been going on with a lot of 2000 chevy Blazer also trail blazers and also the distributor there is no seal under the distributor cap cause it to have moisture and cause it not to run and you have to replace it this is to the company or whoever's in charge now the fuel system itself is called a spider sense or what I call it not to run it all the time they must be some type of filter besides the one on side of the vehicle itself because they go out within a year or maybe two years or so this must be addressed so hopefully I get some information to help fix the…”
NHTSA complaint #11216998, filed 2019-05, 152,800 miles“At 90,000 miles my fuel gage became erratic, chevy dealer says it's the fuel pump. At a cost of $800.00 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!”
NHTSA complaint #10231216, filed 2008-06, 90,000 miles“The fuel sending unit is operating erratically, causing the gas gauge to be inaccurate. The cost of repair is $400.00 for a new sending unit/fuel pump and $200 for labor! I have heard from other GM owners that this is becoming a common problem. Gm will never get my money for a new car again if they don't own up to this problem.”
