NHTSA recall 17V448000
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2016 smart fortwo vehicles. In these vehicles, the lock nut that secures the parking brake cable to the parking brake lever may loosen over time, resulting in increased parking brake lever travel before the parking brake engages.
Safety consequence
As the parking brake lever travel increases, the holding force may decrease to a point where the vehicle is no longer safely secured in all parking situations, allowing the vehicle to unexpectedly move when parked on a slope, increasing the risk of a crash.
Remedy
MBUSA will notify owners, and dealers will replace the parking brake cable lock nut, free of charge. The recall began September 20, 2017. Owners may contact smart customer service at 1-877-496-3691.
Additional notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
