The problem
Certain trucks fail to comply with the requirements of federal motor vehicle safety standard no. 121, "air brake systems." an internal control and check valve within the air brake application valve assembly was configured improperly, preventing air from flowing through the brake system as designed. In the event of an emergency stop, the vehicle's stopping distance would be increased.
The risk
If stopping distance was limited, a vehicle crash could result.
The fix
Dealers will replace the air brake application valve assembly on c-series or reroute the air brake lines on t-series free of charge. The recall began on September 20, 2006. Owners May contact Chevrolet at 1-800-630-2438, GMC at 1-866-996-9463 and Isuzu at 1-800-255-6727.
