NHTSA complaint 11090969THIS NEW MERCEDES-BENZ ML400 HAS A MANUAL TRANSMISSION FEATURE THAT WITHOUT REASON REVERTS BACK TO AUTOMATIC WITHIN ABOUT 10 SECONDS WITHOUT ANY REASON. THIS PREVENTS THE DRIVER FROM BEING ABLE TO CONTROL TRACTION IN SLIPPERY OR OTHER DIFFICULT CONDITIONS, WHICH CLEARLY WAS OUR EXPERIENCE.
