The vehicles in the GLE/GLS, C-Class, E-Class, S-Class, GLC, CLS, and G-Class series with diesel engines could develop a leak, the Stuttgart-based luxury carmaker said in a letter which sent to the customers concerned on Wednesday.

“It was found that the coolant pump, which can be controlled via negative pressure, could have a leak between the coolant and negative pressure circuit in the vehicles,” the company said. (ILKHA)
