The defect
Daimler Trucks North America LLC (DTNA) is recalling certain 2015-2016 FCCC S2G trucks equipped with an 8.0L propane engine and an Allison transmission. The transmission grade brake on these trucks may not deactivate when the disable switch is depressed, which can cause a loss of traction in certain icy, or other slippery conditions, due to aggressive downshifting.
The risk
If the transmission grade brake stays engaged, unknowingly to the operator, in low-traction conditions, it can increase the risk of a crash.
