Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“At approx. 50,000 miles I had total transmission failure in my 2000 Chevrolet Trailblazer. This vehicle was used under normal conditions. The result was a replacement of the transmission (GM rebuild) installed at a dealer for cost of approx. $1800.00 which was unacceptable that I had to pay anything in my opinion, even though the vehicle was out of warranty. I have spoken with other owners who experienced the same issue.”
NHTSA complaint #10128369, filed 2005-07, 50,000 miles“I have researched this a lot and found the internet full of problems with blazers and the transmission going out / the dealership also told me this is a common thing for blazers (the trans going out) in west virginia I was told by a sales department that this is common for chevy blazers. Gm told me and some other internet people that there is nothing that can be done. I think an investigation needs done /truck has always had a weird noisy that which we complained about and we were told until something happens there is nothing that can be done. …”
NHTSA complaint #10106487, filed 2005-01, 70,000 miles“2000 chevy Trailblazer had transmission failure with only 71,000 miles. Dealer claimed that it was a natural thing for these transmissions to fail. Gm customer service refused to assist even though hundreds of these type complaints have been filed. An immediate recall should be imposed on Chevrolet for distributing faulty transmissions that fail even before maintenance is due. I would not be surprised to see a class action lawsuit over this due to the high number of transmission failures. …”
NHTSA complaint #10180608, filed 2007-01, 71,000 miles“When driving at any speed 4-wheel drive changed from auto 4wd to high 4wd, then tried shifting into low 4wd without warning. The switch was set to auto, therefore, the problem shouldn't have occurred.”
NHTSA complaint #10057485, filed 2004-02, 22,504 miles“Powertrain transmission - 50,000 miles and the transmission goes out.... Sunshell I believe is what they called it. Highway miles only and serviced regularly. This should not happen!”
