Engine is a 6.5 turbo diesel. I bought this vehicle used so have no previous history whether it happened before I owned it. Vehicle engine started to die while driving, occasionally at first. It would restart immediately sometimes and sometimes it had to sit for a while. This problem started in years previous to 2010 intermittently but became more frequent in 2010- 2011. Didn't matter what speed I was traveling, it would quit on the interstate going 75 mph or in driveway going 5 mph. Shut off without warning and immediately like someone turned the key off. All power steering and power brakes failed but fortunately I was able to pull the vehicle over to the side of the road and stop it when it happened, only because I knew how to steer with out power steering and had the strength to do it. With others this could easily cause serious accidents. Multiple attempts were made over the years with a mechanic to find the problem with no luck. Finally someone suggested replacing the pmd module which I did in 2011 and it solved the problem for 3 more years. It is now happening again. I was told the pmd module needs to be located outside of the engine compartment because it gets too hot and causes this failure. I believe this constitutes a poor design and a defect that needs to be rectified. Since this happened to my vehicle I have talked with several other people just in my area who own the same type of engine and have had the same problem and others in other areas.
