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.

I have had the same issue of the car, being in park for over 5-10 minutes, suddenly lunging forward. It is quiet startling to have it happen. I worry that when I exit the car with the engine running ( due to passengers still in the car) something will happen. This has happen several times with me.

The vehicle will stop acceleration while driving. The message states "pre-safe functions limited". when the car shuts off for no apparent reason when driving at 70 mph on a highway is really unsafe. I have to coast to the side of the road to safety. I have turn the vehicle off and then I will be able to restart the engine. I have not taken this into my Mercedes dealership yet.

Multiple episodes of "pre-safe functions limited" occurring. When this message appears the car suddenly loses acceleration and you are not able to go above 30 mph despite pressing on the gas pedal. This has occurred on normal 35-45 mph streets but has happened multiple times on the highway when the car is going 65 mph. Luckily, no motor vehicle accidents have occurred because of this issue. The car is able to accelerate and function normally after turning the engine off and on again. Have gone to Mercedes dealer multiple times to fix issue. The first time it occurred, Mercedes updated system software. Next they replaced vehicle sensors. Most recently they claimed the issue was due to oil pump failure. They replaced an oil control valve and oil pan. Four days after the repair I received the same "pre-safe functions limited message, my car stalled while I was going 40 mph. I have returned the car to the dealer once again to run diagnostics. This has occurred many times in the two and a half years that I've owned the vehicle. It is currently at 49,200 miles and has been properly serviced. Each time I bring the car in for this error message Mercedes replaces a new part but it does not solve the problem.

While driving on the highway, I heard a sudden loud explosion, the panorama sunroof shattered and glass rained down on me and everywhere within the car. There was no evidence of anything hitting the car or the sunroof, it just spontaneously exploded.

Car has been lunging forward when in parked for more than 5 to 10 min since I have owned the car. This car was bought on February 20, 2015. Since then, I have brought it back to the dealership 3 times for the same problem. The third time that I brought it to them, they followed up with saying that it is the make of the car and every cla does that. This is a huge safety problem and it needs to be fixed.
