Owner reports
Selected complaints filed with NHTSA by 1999 Chevrolet Blazer owners, lightly cleaned up (personal details are redacted by NHTSA).
Lower ball joints wear out prematurely. The consumer stated the vehicle was on its fifth set of lower ball joints and it sixth idler arm. The cruise control was inoperative, the grill guard was loose, the rear differential leaked, the door latch was inoperative, the sending unit was replaced, the battery was replaced, the door was readjusted due to a vibration, the left front hub assembly was replaced, the exhaust made a noise, the tensioner and serpentine belt was replaced, the front axle seal leaked and the intake gasket leaked.
The tread from a uniroyal laredo tire came off while I was driving on the freeway. I lost control of my vehicle momentarily until I was able to countersteer to correct the weaving and unstable driving of my vehicle. As the tread came off it damaged my wheel well, undercarraige behind the wheel, rear bumper and body trim. I had my son and three of his friends in the car at the time.
The Chevy Blazer had multiple defects. The air bag did not deploy upon impact. The vehicle had air and water leaks around the windows, oil was being consumed abnormally, the seat belt had come loose and the brakes did not work properly. The consumer was informed that the vehicle had been wrecked. The consumer had three accidents in which all were frontal impacts.
Consumer complained about a ball joint problem. It was discovered that the ball joints were defective. The consumer contacted the dealership, who was asking for $1200.00 to repair the defective ball joints. The hinges on the drivers door have rusted extensively causing the door to sag when opened.
Both the driver side door and front passenger side doors,door bushings went out,causing the doors to droop and cause damage to the frame latch...attempt to fix the problem was unsuccessful. The bushings need replaced and welding work needs to be done on the frame.
I have 1999 Chevrolet Blazer with 60000 miles the drive side door has fallen down about 1 inch in the last two months sometimes I have to lift up on the door to get it to shut if this keeps up the door May fall off.
Vehicle experiences stalling, after stalling there is a burning smell, dealer has replaced the fuel pump, crank sensor, map sensor, PCM, fuel pump module, vehicle still experiences stalling, consumer feels problem is an electrical problem. Ses light flashed at times, dealer replaced coil wire. Keyless entry inoperable, dealer replaced receiver, remote module, and reprogrammed transmitters. Consumer states vehicle has excessive wind noise on both sides. There is a clunk when backing up and turning left or right. Overhead panel goes blank in morning, when first starting vehicle, dash and gauges will not light up, and overhead compass was replaced. Consumer states gas mileage is not as good as it used to be. Ses light illuminated.
Dt: the front driver side door was falling off. The way the door was designed made it impossible for hinge to hold the weight of the door. The door was repaired three times by the previous owner. Each time it was repaired it did not last for much more than a year. Consumer had the dealership give her an estimate. When she contacted the manufacturer, they said they might do something for her after she had the repair done. The consumer felt this was a manufacturing defect, and they should pay for the repair or replacement. There were other problems with the vehicle. The seat did not work. There were other parts of it that either broken or were breaking.
I have contacted Chevrolet and they will not assume responsibility for the frame weld failing. They acknowledge the vehicle is unsafe to drive, but offer no remedy other than replacing the frame at my own expense. They could not provide me with a cost to do this type of replacement. I feel this is a potential safety issue effecting other owners. I would like to see Chevrolet take responsibilty for what is obviously a manufacturing defect. I realize the vehicle is out of warranty because of miles, but it is a 2 year old vehicle which a reasonable person should expect the frame to last beyond that time.
Consumer reporting excessive wear of brake pads and rotors, from 17,614 to 35,500 miles there were three sets of brake rotors and two sets of brake pads replace on the vehicle, and the problem reoccurs. The dealer has been notified. Water leak on passenger side floor, driver side door rattles going over bumps, both front windows outer molding comes off, moldings replaced, humming noise from front wheels when coming to a stop, wheel bearing / hub replaced.
