Caelum is on a distinguished road

I have a 2010 Laramie, and in about a month I've had three issues with the Serv4wd. First the truck went into 4wd, but it would not come out. Dealer replaced the shift motor "actuator".

A few weeks later the light came on a gain, dealer found nothing, reset the computer. The next day it came on again, took it back. This time the dealer said it was a faulty engine coolant temperature sensor (they told me if this fault the computer would show a serv4wd). They replaced it, drove it for about 2000km with no problems.

Today, again 4wd light as soon as I shifted into 4wd, before even moving, and again it would not come out of 4wd. Dealer said the shift motor "actuator" was faulty and replaced again.

Very annoying! If this happens again I will have to bring up the drive train control module. Thanks for the thread!
