“Rear main engine oil seal on the Mercedes-Benz E350 bluetec fail after 90,000 miles, the problem is that the engine has not been broken in yet and it's leaking from the rear main engine oil seal. This is a $1300.00 plus fix and I should not be experiencing on $50,000.00 automobile with less that 200,000 miles on it. Mercedes-benz should be fixing this problem at their expense not mine.”

NHTSA complaint #10715221, filed 2015-05, 92,000 miles“1. Oil leak from the oil cooler assembly in the diesel engine. Obviously, a cheap gasket was used to seal it! Mb, with diesel experience of over 80 yrs, should know by now what material they use in their diesel engine. This defect will develop in every car they made in the same way and they should recall the cars and correct the issue 2. The driver seat is torn along the tuft in the seat.this is happening across the board ion all mb cars using the same materials. Again, it is a material issue and should be corrected. Old mb seats lasted for decades!”
