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.

While driving on the highway, I attempted a heavy acceleration to get the car up to traffic speed. Two times in the past 60 days, the car seriously malfunctioned with multiple dashboard indicator lights and the main text "pre safe functions limited" accompanied by a total loss of speed control. The accelerator became 100% unresponsive and I had to coast to an emergency lane. There was significant danger in both instances as I had to cross multiple lanes of traffic with no power to get to safety. The weather was clear and the external sensors were not obstructed by dirt or snow- which has previously caused the pre-safe functions limited message. I believe that the multiple errors indicated on the dashboard are all erroneous to the core issue of a sudden and total loss of power upon heavy acceleration. The resolution was to shift the car into park, push the ignition button as if turning the vehicle off, wait and restart. The car operates normally upon restart. Note that the engine appeared to already be off prior to shifting into park. It is as if the heavy acceleration killed the engine. This issue has potential fatal consequences if the driver is unable to get the car out of the lane of high speed traffic-- as I was in. A less experienced or panicked driver could easily fail to handle the situation and get rear ended at high speed as the car can only be reset by getting it into park and restarted. Similar blog posts online report the same with other Mercedes vehicles. I have had the car for four months and it has happened twice. Seems like a software/electronic issue causing the mechanical issue to me. Very dangerous.

The transmission jerks between 3-4 gear up shift change, creating instability on wet or slick road conditions which can cause your car to lose control. Furthermore, the jerking created can create a car accident or injury in low speed, stop an go traffic. Mercedes Benz claims it is performing as designed and is not accepting liability for there defective product.
