I have been noticing that my brake lights will come on for no reason when the truck is not been run. Sometimes they will stay on for a long time, and sometimes will cycle at some random rate. I have used they unlock/lock cycle and this does not always work to stop it. When I start the truck, it stops the lights turning on for a few hours up to a day.
Any ideas? Really frustrating.

since you're under warranty, the best thing would be to have the dealer put it on a scanner. You could have a problem TIPM. Sometimes they also have a flash for the computer that can fix things like that. Our trucks are known for having mysterious anomalies that go away on their own too.

 

I had a topper put on my 2003 hemi hd and had the a simular problem. Come to find out, were the installer spliced in the brakes lights in. the used a non water tight connector! If you have any add on check out the connections.

 

Triton is right. Have the dealer hook up the STAR scan and see if there are any codes in the Totally Integrated Power Module (TIPM). Also make sure it has the latest software....

 

Cool thanks for the heads up, It goes in tomorrow, needs to have left front speaker fixed anyway!

 

Well it turned out to be the brake switch, and it had burned out the two taillights in the process.
