Owner reports
Selected complaints filed with NHTSA by 2000 Chevrolet Blazer owners, lightly cleaned up (personal details are redacted by NHTSA).
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. …
Fortunately, I had just gotten off the freeway and was looking for an address at a slow speed. All of a sudden the car lurched; I had no steering; I lost all electrical control; the car ground to a halt; smoke came out from under the hood. I and a friend got out of the car. Fortuitously, fire trucks appeared. It turned out they were returning from another incident as I could not believe the immediacy of their response. They took over preventing further aggravation of this situation. The battery was boiling. All the electrical wire harnesses were melted. The upper suspension control arm was broken. The firemen's observation was, if I had been going any faster, the car could have flipped. After being towed to a nearby mechanic, I learned the upper control arm had broken. It impailed the starter which shorted. …
Refer to odi id number 760100, 8008263, 8013241, 10016706, 10001738, 566417. I have detected this same problem on my 2000 Chevrolet Blazer purchased in January 2000 at a dealership in seattle washington. The throttle pedal sticks on takeoff/startup from a stopped position (I.e. Stop light/sign). I have to exert extra pressure on the pedal to get the vehicle moving. When I exert the extra pressure on the pedal, after about 1 - 2 inches, it breaks free and lunges from the stop. It also sometimes happens when I try to accelerate on the freeway, not from a stopped position. My wife has also experienced this problem. We just got home from a trip through california from 8 days of driving and have had this problem the whole time. I first experienced this problem about a month ago and thought I might need to use wd-40 in the linkage from the pedal. This did not help. …
Never took in for rear wiper. Started leaking oil, so took to dealer here in roosevelt 21, dec. Started to provo jan. 10, cruise control went off, speedometer would not work, this caused the car to not shift. Pulled off road as car stops, turned car back on, turned around to return home. Afraid to continue over mountains. Took to murry motors, could not find anything wrong. Took for a 30 minute mile ride and it happened again. Will take back this following Monday to be checked again. Can not drive if it wont shift. Took to murray motors for oil leak. They replaced two hoses. Not connected properly, causing leak. Thanks mrs. Riding. ****dimsii ivoq entry posted after 12/12/02 cut-over to artemis*****770837
Vehicle experienced slow acceleration. This occurred when the t speed accelerated to 60 MPH. Consumer had to apply excessive force to the gas pedal when this occurred. There were 35-60 second delays before vehicle accelerated. Vehicle had been serviced 3 times by the dealership, who replaced several other components, but they did not address the slow acceleration problem.
Accelerator sticks when applying pressure from a stopped position requiring extra force on accelerator to get vehicle to move. This extra force sometimes makes vehicle lurch forward. In my opinion, this sudden movement creates a very unsafe driving condition. This condition started as an intermittent problem but is now occurring almost every time the vehicle is driven.
While driving with speed control on, vehicle started to accelerate. Also, air bags deployed, knocking consumer out. Vehicle crashed and consumer was injured. Consumer states that the deployment of the air bag is what caused the accident.
The gas pedal sticks 75% of the time upon initial acceleration, whether that is from a stopped position or accelerating after slowing. The sticking is such that force has to be exerted to get the pedal to depress thereby causing lurching of the vehicle. In parking lot situations or on icy roads this can be potentially very dangerous. Also, both front seat adjusters that allow the seat to be repositioned have broken off while trying to repostion the seat. When we reported these items to our dealer they said these are common problems they are seeing frequently. If this is so I feel it is a defect of the manufacturer. The seat levers were plastic painted to look like metal and both broke off within a week of each other. Dt
Consumer was traveling about 35mph and was entering freeway when vehicle started to acellerate and engine just rise up, like it was in neutral, and vehicle decreased speed. Transmission was replaced inside of vehicle . Dealership was aware of this problem there were several incidents happening on this vehicle. The vehicle was brought to the dealer five times for this problem. Each time the dealer replaced different component air flow sensor, fuel pump and transmission. The provlem still reoccurs and the dealer can not find the cause.
Consumer states the accelerator sticks upon take off, consumers wife was backing in a parking space when the accelerator became stuck, she thought she was not pressing hard enough as she was backing in, she then pressed more firmly on the accelerator until it quickly freed itself and then rocketed backwards, she was able to quickly hit the brakes and was able to bring the vehicle under control, consumer was informed that the issue is considered regular maintenance, however consumer believes this to be a safety defect.
