Re: 08 Grand overland Unlock problems and intermintent start/power.
I call it the "key fob Gremlin"...search around on here...but what I found to work was moving the battery inside the fob. for some reason the contact was not proper and it works everytime. IDK about the power issue, again Gremlins. My 08 has shut off once on the freeway while I was going 80!! And I had a amp/sub issue last week...neg terminal reset worked for me...tried one in a while? Disconnect - terminal and step on brake for 30 secs. GL
