German carmaker Mercedes-Benz recalls about one million older cars globally. Due to a problem with the braking system, the federal transport authority (KBA) explained.

The federal transport authority (KBA) said in a statement dated June 1. KBA reported late Saturday in German media that the recall affected cars built between 2004 and 2015. It affected the SUV series ML and GL and the R-Class luxury minivan.

“Corrosion on the brake booster can in the worst case lead to the connection between the brake pedal and the braking system interrupted,” the KBA explained.

“As a consequence, the service brake can stop functioning.”

The KBA said that globally 993,407 cars recalled, including around 70,000 in Germany.

Mercedes-Benz also confirmed the recall later in a statement sent to AFP, saying the move was based on “analysis of isolated reports for certain vehicles”.

“In rare cases of very severe corrosion, it might be possible for a particularly strong or hard braking manoeuvre to cause mechanical damage to the brake booster, whereby the connection between brake pedal and brake system would fail,” Mercedes said.

“In such a very rare case, it would not be possible to decelerate the vehicle via the service brake. Thus, the risk of a crash or injury would be increased.”

The company explained that it would “start with the recall immediately” and contact the owners of the “potentially affected vehicles”.

“The recall process will involve inspecting potentially affected vehicles and, depending on the results of the inspection, replacing the parts where necessary,” the company said.

“Until the inspection takes place, we ask our customers not to drive their vehicles.”
