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. …
Purchased 2000 Blazer 11/24/00. Many problems since. Transmission cooler line, warranty repair. Oil cooler lines, upper and lower, warranty repair. Warranty expired and they are leaking still. Problem never really fixed. Idler arm, warranty repair. Driver side recline handle driver seat fell back would not return to upright position, warranty repair. Both front wheel bearings and rotors, warranty repair. From day 1 numerous rattles and squeaks. Door panels rattle constantly. Passenger seat rattles and squeaks. Windshield wiper entire arm came off, repaired at my expense. Out of warranty, at 41,699 miles but not even (2) years old, transmission had to be rebuilt at my expense. Chevy customer service is a joke! Cost of transmission $2,442 and the cost of a two week car rental. …
Numerous problems. All after warranty expired. Have a 2000 Chevrolet s10 Blazer 2 dr. It is a 4x4 with a 4.3l v6. Seat handles broke a couple of times. Terrible lifespan on those. Had replaced twice. Replaced defective alternator. Wasn't holding charge. Also LED to a new battery and serpentine belt. Had to replace fuses for fuel gauge. It was jumping all over the place giving incorrect readings. Had to replace numerous fuses. Terrible whining coming from the fuel pump. Chevy dealer tells me it is testing fine. But now I am having what seems like vapor lock problems on hot days. I'll go to accelerate and the vehicle will go no where and then catch and accelerate. Acts like it's going to die but hasn't yet. Diagnostics showed nothing. Terribly sporatic and makes vehicle unsafe and unreliable. It has 60,000 miles on it now. …
I have a 2000 Chevy Blazer with 44,000 miles. Since the warranty expired in July I have had numerous problems that seem to be common among owns of this type of vehicle. GM refuses to address these items since the car is just out of warranty. Some I consider to be safety issues. They are as follows: accelerator pedal sticks, seat recliner handle is broken, fuel gauge does not work properly and 4 wheel drive will not engage. For a vehicle that is just over 3.5 years old this is unacceptable. I will probably not purchase another GM vehicle due to these problems and will probably purchase a european auto, their engineering and customer service are far superior to our us automakers.
Consumer was inside the parked vehicle, adjusted the driver's side seat and seat lever sheared off. Driver 's seat failed to move back and forth on its own. Consumer contacted took vehicle to the dealer for inspection, and mechanic repaired the part. But this problem recurred, and had not been resolved. Consumer contacted the dealer, who informed consumer that the warranty expired. Consumer was responsible for payment for parts and labor. While adjusting the seat the latch that goes up/down broke the second time. Consumer paid $100.00 deductible to get it repaired. Warranty expired.
Owns a 2000 Chevrolet Blazer zr2 with 68000 miles. The heater blows cold air only. The alternator has been replaced at least twice. I replaced it once, and previous owner replaced it once . Battery has been replaced at least twice. All ball joints replaced at least once to my knowledge. Fuel gauge broke before 50000 miles. Seat handle on passenger's side broken before 50000 miles. Tailgate won't open. Passenger side windshield wiper only moves half the time. That is all that I can recall right now.
Suspension front and rear-upper and lower ball joints(front)left and right sides idler arm and both rear leaf springs needed to be replaced. Warped rotors left and right. Left door lock cylinder fell off. Dealer replaced right rear speaker under warranty. Front seat recliner levers replaced resulting in split cost with dealer. Manufacturer rep offered labor/parts split for suspension work and brake work for $1400.00. Refused work on door lock in excess of $300.00.
The seat back adjustment levers broke on both the driver and passenger seats. The metal shaft is defective. The cheverolet dealer quoted $300 per seat. There is a service bulletin issued #060601 for this problem and numerous complaints to the NHTSA web site. Cheverolet will not correct the problem because it has not been identified as a safety issue. If the drivers seat gets broken in the full recline position, this would be a safety hazard for the driver.
Frontal seat adjuster lever broke complete off without excessive force being applied. This made driving difficult and unsafe in the current position the seat was in. Also, both front doors were leaking and were hard to open or close even when the automatic door lock was engaged. Dealership indicated that the door's bushing and pins needed to be replaced.
The seat recliner on the drivers side broke. After fixing, the seat then squeaked and rattled. Dealership saaid I have a broken seat frame. Dealership won't pay for damanges. This is the second general motors vehicle that has a broken seat recliner. The first one was a 98 GMC jimmy. Same thing happened.
