The German automaker does not have the parts necessary to repair the problem.
This is an official statement about the issue:
Mercedes-Benz AG determined that certain GLE/GLS (163 platform), C-Class (205 platform), E-Class (213d platforms), S-Class (223platform), S-Class (223platform), S-Class (223platform), S-Class (223platform), E-Class Coupe/Convertible (238platform), GLC (253 platform), ClS (257 platform), and G-Class (463 plate) vehicles with diesel engines, the coolant pump which is controlled via vacuum might leakage between the coolant circuit and the vacuum system.
Coolant may get into the vacuum system and cause damage to various parts. In the event that electrical switch valves come into contact with coolant, the temperature of the parts may increase in isolated cases due to an electrochemical reaction.
Mercedes-Benz was in the news earlier this week when it launched the EQXXX concept, which is the most aerodynamic and efficient vehicle the brand has ever produced. The Daimler-owned automaker is back in the news, but this time for the wrong reasons. It is required to recall approximately 800,000 vehicles. However, the brand doesn’t have the parts.
The first report by Germany’s Bilder newspaper was that hundreds of thousands Mercedes cars manufactured between January 2017 to October 2021 could have a leaky coolant pump. This could cause extreme heat, increasing the danger of fire, in rare cases. Bild published a letter Mercedes addressed to the owners. According to Reuters, the German company confirmed that the letter was genuine and a Mercedes-Benz spokesperson confirmed the issue with us.
Mercedes isn’t having the greatest problem with the number of affected vehicles. Bild states that Mercedes doesn’t have all the parts needed to fix the problem. The reason is due to disruptions in the supplier network caused by coronavirus. Although it is not known when the components will be available, the campaign will be launched.
In a letter sent by the company to affected car owners, it stated that “the affected vehicle should not be driven in any way other than prudently and use it only as much as necessary.” Certain GLE/GLS models, C-Class/GLS, E-Class and S-Classes are affected. However, these cars are powered by diesel engines. This means that there are likely to be very few affected cars in North America. However, we will update this story when we hear from Mercedes.
