Example complaints

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

“Several problems.. Multiple failures of glow plugs (known GM problem) and nox exhaust sensors, high def use, unusual buildup in the exhaust filter requiring many dealer visits, downtime, repair costs and extremely poor fuel mileage. Glow plugs often fail at initial start when system is cold .. Oat has been from about 45 to about 90 degrees fahrenheit. Altitude, about 20 to 1200 ft asl. Dealer serviced only. Vehicle has no mods!!!!”

NHTSA complaint #10905646, filed 2016-09, 12,000 miles

“The Transmission Control Module failed causing the vehicle to loose power and operate only in limp mode . General Motors does not have a replacement module available, leaving the vehicle inoperable. GM has no reliable information as to when a module will be available. I had to use a third party service to try and repair the module for a cost of over $1,200. This seems to be a common problem with the 2008-20015 GM Duramax with the Allison transmission.”

NHTSA complaint #11516029, filed 2023-04

“The vehicle's TCM has apparently failed as evidenced by CEL code U0101 , low power ( limp mode ), hard shifting, no gear selection indicator, and extremely slow acceleration. Vehicle is currently available for inspection, but will be receiving a replacement TCM soon. Myself and others' safety was put at risk due to my the vehicle's inability to continue through an intersection at a reasonable rate. The problem has not been reproduced by a dealer/service center, nor has it been inspected by anyone since the incident. …”

NHTSA complaint #11654876, filed 2025-04

“Transmisión control module stopped working while driving on the highway. It went from going 70 miles per hour on the highway to 15 miles per hour. Very scary and dangerous.”
