“Relay for 4 way flashers is clicking, online my problem with flasher relay and brake lights is listed under recall 01073b. I have no idea if this recall was done, done properly or just timed out.”
NHTSA complaint #11406641, filed 2021-04, 120,000 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.”
NHTSA complaint #10609204, filed 2014-07, 145,000 miles“It started with my gauges bouncing all over going on and off , then it felt like the brakes were on and I had to give it alot of gas to get going.now the dash will work when I turn the key on but as soon as it starts it goes out with the exception of the oil pressure and the charging gauge. The transmission isnt working right at all and I dont dare drive it anywhere. The fuse box under the hood does not test right, only about half of it has power and I am at a loss there! There has been electrical probnlems with it ever since I bought it.”
NHTSA complaint #11351063, filed 2020-08, 140,000 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…”
