Mercedes-Benz recalls over one million older vehicles worldwide due to potential issues with their braking systems.

The automobile company announced that it will contact vehicle owners whose brakes may be damaged by "advanced corrosion."

There are 993,407 automobiles affected by the recall, including 70,000 in Germany.

A comparable number of Mercedes vehicles were recalled last year due to a safety concern with their emergency call system.

The business reported that the ML and GL series SUVs and R-Class luxury minivans involved in the new recall were manufactured between 2004 and 2015.

"We have found that in some of those vehicles, the function of the brake booster could be affected by advanced corrosion in the joint area of the housing," Mercedes said in a statement on Saturday.

"It might be possible for a particularly strong or hard braking manoeuvre to cause mechanical damage to the brake booster," it stated.

"In this extremely uncommon circumstance, it would be impossible to decelerate the car using the service brake. Consequently, the probability of an accident or harm would increase "it added.

Mercedes stated that it will initiate the recall immediately and that the procedure will involve evaluating possibly defective vehicles and, if necessary, replacing parts.

Because of a flaw in its "eCall" feature, which warns emergency services of an accident and sends the vehicle's position, the business recalled over 1 million cars in February of last year.

Due to the flaw, it was possible to send the wrong location.

As the issue was software-related, most of the patch was performed "over the air" via a wireless download utilizing the vehicle's existing mobile data connection.

Since 2018, the eCall system has been mandatory for all vehicles sold in the European Union.
