Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My transmission cooler lines were leaking and I'm concerned about it due to the transmission fluid being a combustible material. If this material dripped onto a hot exhaust and ignited while parked in the attached garage of our home, it could pose a major safety hazard...not to mention it could do to the neighbors home being relatively close. Thank you for your time.”
NHTSA complaint #10221234, filed 2008-03, 35,000 miles“2006 chevy silverado hd diesel with allison trans-- transmission cooler lines leaking, dealer said there has been no known problem. I searched online and found hundreds of similar complaints. So I was forced to pay $700 to have the lines replaced, which will probably end up leaking again. This is obviously a defect, as I have 3 other chevy trucks, none of which have ever leaked from the trans lines, and some are over 10yrs old.”
NHTSA complaint #10372344, filed 2010-12, 23,000 miles“Starting 4 days after delivery of this new light duty truck with diesel engine and 6 speed heavy duty automatic transmission, the transmission has almost continually malfunctioned, causing what I believe are dangerous conditions putting myself, my passengers, other drivers, and pedestrians at risk. …”
NHTSA complaint #10166198, filed 2006-08, 400 miles“The vehicle makes a high pitch noise while lightly accelerating. It strongly appears to be coming from the transmission. The dealers to date has refused to acknowledge this problem with my vehicle. I have had this complaint since the first week of purchasing the vehicle. I presently have 2200 miles.”
NHTSA complaint #10177138, filed 2006-12, 200 miles“I own a 2006 Chevrolet pickup truck and found that if you turn the key one clip forward you can pull the shift lever into any gear including neutral without stepping on the brake. I checked around and found that any Chevrolet truck, van or pickup all the way back to 2003 will do the same thing. I heard but don't know for sure that a young boy was hurt when he turned the key and pulled the lever down crashing the truck.”
