Mercedes-Benz USA (MBUSA) is recalling 432 model year 2017 Mercedes G550 & G550 4x4 Squared vehicles.
The vacuum hose for the brake booster may collapse resulting in increased braking effort, increasing the risk of a crash.
What to do
MBUSA will notify owners, and dealers will replace the vacuum hose, as necessary, free of charge. Parts are not currently available.
Owners will be notified of the recall in January 2018 and receive a second letter when the parts become available, currently expected to be in March 2018.
Owners may contact MBUSA customer service at 1-877-496-3691.
