NHTSA recall 93V067000
Service Brakes, Hydraulic · Mercedes-Benz USA, LLC
Details
What's wrong: During the removal and installation of the air filter housing while servicing the vehicle, it is possible to misroute the preformed vacuum hose and damage the check valve in the vacuum hose. If the check valve is damaged, loss of sufficient brake power assist will occur.
Why it matters: Lack of sufficient brake power assist will increasestopping distance and could result in a vehicle accident.
The fix: Replace the preformed vacuum hose with a newly designed preformed hose with a relocated check valve which will eliminate the possibility of the check valve being damaged.
