Mercedes-Benz will recall over 660,000 cars this year from China amid likely oil leak, the Associated Press reported.

A seal between the high-pressure fuel pump and a low-pressure fuel pipe may weaken over time, and it will lead to oil leak when the engine starts in cold weather, China’s State Administration for Market Regulation said in a statement.

The recall of 668,954 vehicles includes C-class, E-class, V-class, GLK-class, CLS-class, SLC-class, GLC SUV and VS20 VITO models.
