I have a 2003 mercedes s430. The other day my wife was going down the highway at 65 MPH when it just shut off in the middle of the road. This is very dangerous. How do we allow a vehicle to operate on the highway that would just cut off in the middle of the road without at least giving you a chance to get out of the road. Thanks

While driving getting ready to enter the highway my 2003 mercedes s430 instrument panel went out. The gauges got stuck on what they were while driving. I wasn't able to see anything on the panel. I took it to the nearest shop and they changed the fuse, however the fuse blew right back out each time they changed it. The car was still drivable. I haven't had this car for 1 year yet and I am lost at what to do. The shop said the instrument chaise will work but something is blewing the fuse. I was also told that the aluminator in the instrument panel is faulty and needs to be replaced. Any help with this issue is helpful.. Please help as this car has become a nightmare (instrument panel, doors don't lock, passender seat moves at wierd times, and the air strut busted) instead of a good dream. I have read a number of issues with the instrument panel failure in these cars. I wish I would of seen this before I purchased it. Mercedes needs to cover the cost in fixing this issue.

A few days before the main incident, my 2003 mercedes s430 would stall for no apparent reason. I called mercedes roadside assistance, and they told me that I should let the car reset, and this would fix the problem. This happened two times and both times there was a temporary fix after the car reset. A day after the second reset, my car completely stalled and engine shut off completely while I was driving on the freeway causing me to almost get into a few crashes. Mercedes roadside assistance called the tow company, and they took over an hour and a half to get there. It was a very hot day, and I felt very sick from the heat. The car was towed, and it turns out that the crank sensor was faulty and needed to be replaced. Roadside assistance did not tell me it needed to be replaced, but just to let the car reset. There was no warning that the sensor was faulty. There were no lights that came on the dashboard that the sensor was faulty. This is an inherently dangerous defect, that a sensor goes bad with no warning, and the engine shuts off. The sensor was replaced by mercedes for $433.16. I am traumatized by the incident, and I am scared to drive a dangerous car that can shut off with no warning while driving for something as small as a bad sensor. Further, I was misled by mercedes roadside assistance that the part needed to reset, rather than be replaced.
