The carmaker says the vehicle’s brake booster vacuum line may be susceptible to breakage due to a weak connector, causing a leak.
Should this occur, the vehicle’s braking capacity could be dramatically reduced, causing a hazard for the vehicle occupants and other road users.
Mercedes reminds owners that the braking system should still operate, but may require much greater pedal pressure than usual from the driver.
Affected vehicles were sold in Australia between February 2012 and June 2013.
Mercedes-Benz will attempt to contact affected owners shortly, but any owner wishing to learn more about the latest round of recalls should contact their local dealer.
