Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I drove my wife to the pharmacy and after pulling out of the parking lot onto palmdale road in victorville the truck went into to limp mode. The transmission locked up into park at 25mph almost causing a rear collision behind us. The Gmc sierra 3500hd 2009 came to a screeching stop causing a bit of whiplash to my wife and daughter on board. The TCM transmission control module along with the allison transmission failed causing this close accident. The vehicle is inoperable at this time. This is a dangerous defect.”
