Power train
- What is wrong
- 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.
- Risk
- If the transmission grade brake stays engaged, unknowingly to the operator, in low-traction conditions, it can increase the risk of a crash.
- Remedy
- DTNA will notify owners, and dealers will update the vehicle's programming, free of charge. The recall began on May 31, 2017. Owners may contact DTNA customer service at 1‑800‑547‑0712. DTNA's number for this recall is FL-734.
