Consumer Description
While driving on a mountain highway pulling a light duty trailer coasting downhill, the truck went into Nuetral and lost all power. There was no warning lights or messages prior to failure. The display showed "Unable to shift under current conditions". Luckily I was in the right lane and had enough momentum to be able to coast into a breakdown lane on a slight grade with my trailer. The electronics still worked, but the engine would no longer turn over or shift into gear. Had the vehicle towed to the dealer I bought it from and the tech said the engine will need to be replaced. I was lucky this did not cause a catastrophic failure while driving at highway speeds and was able to bring the vehicle (and trailer) to a stop safely. There is already an open investigation against this problem on the NHTSA website, and the claims look very similar to my experience.
