One problem related to power train has been reported for the 2003 Mercedes Benz S430. The most recently reported issues are listed below.
Heater and air conditioner fan motor failed on my 2003 S430. Which is dangerous in seasonal climate conditions I've had to replace this part 2x at 700. 00 on both occurances at my own expense which I dont understand when there is a recall for this same issue for previous years 2000,2001. . Recall#2004 070010. I've also had to change my shifter gear box which jams in the park position and doesn't allow you to drive the vechicle this is caused by a plastic piece that is susceptible to break within the gear box this issue is also expensive for just 1 faulty trans shifter piece that can totally leave your car inoperable.
