Yes I've been to the dealer. My 1500 w/t has been experience electrical issues. While driving the dashboard will light up and all power to the vehicle is lost. Happens intermittently. If I turn the ignition sometimes it starts right up and other times its dead. Sometimes I'll jump in it after it has been sitting and there is no power to anything. Battery has been replaced and checks good. Dealer says it cant find anything wrong. Cant make it more than 20 minutes without experiencing the issue. Some times dies while pulling out into an intersection.

Has the dealer tried to flash the computer? They had to do that to me last year when my truck wouldn't start.

 

HelpGeorge,

I am sorry to hear that you are experiencing this issue. I see that you state that your dealership can’t find anything wrong. Did your dealership not experience the issue or they can’t find what is causing the issue?

Thank you

The dealer could not recreate the problem so didnt want to do anything. They had it for 2 days. I cant drive more than 20 minutes without it happening. I'm back again today after having the vehicle die on a 4 lane highway with no shoulder. Not sure if they're spending the time they need to diagnose the problem. A 5 minute drive may not recreate the problem. I basically have a 25K vehicle that cant be driven. I'm at the dealer service standing next to a guy with an 08 with the same problem. HA!

I can get power back to the vehicle by tugging on the positive battery cable so I'm going to have them replace that.

 

HelpGeorge,

I am sorry to hear that your dealer couldn’t recreate the issue. What did your dealership have to say the second time you brought the vehicle in? Did you have them replace the battery cable?

Thank you,

In the end it was corrosion on the cable according to the dealer. They cleaned the connections and reattached. There did not appear to be corrosion at the battary terminals to the eye. Its been running good for 5 days without experiencing the problem
