Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

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!

Oil cooler leaking oil. This is a $2200 fix. I should not be experiencing this on a $50,000 automobile with less than 100,000 miles on it. Mercedes Benz mbusa should be fixing this problem at their own expense.

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 plus fix and I should not be experiencing on $50,000 automobile with less that 200,000 miles on it. Mercedes-Benz should be fixing this problem at their expense not mine.
