I bought my 2015 in August of last year with 8K miles and here I sit at the dealership with 15K for the second time in 4 days.

Truck loses gauges while driving and throws all the warnings (tire pressure, temp, hill descent, and on and on). If I turn it off it won't start. I disconnected the battery first time it happened, about a month ago, and it restarted. Thursday it wouldn't start until the tow truck driver got it off the flatbed at the service center (go figure). This time I got it on video and parked it at the service center myself. I showed the foreman the video.

The service advisor told me it needed a software update last Friday when I picked it up, which is another way of saying they had no idea and didn't put much thought into it since it was running when they had it. The notes said they did a diagnostic, found no codes, and "drove it on a bumpy road" with no issues. Really?

This is extremely frustrating! I hope they actually do something this time. The damn thing started again before I left it with them!

 

You wouldn't be the first with these symptoms, I think you need to read thru these threads and the posts in it

There are some other owners who think it has to do with a connector by the parking brake. You can have a read of the posts and gather some information from there

 

There's a few threads on here like this in the 6.7 and 6.2 sections something to do with a wiring harness or module that mounts to the parking brake assembly. I think there's also a tsb but not sure I'd head over to whichever forum applies to your engine and look for a thread that has a title simple to your problem. I'll link it if I can find it in the next few minutes. Edit looks like pocket beat me to the punch and linked them while I was typing.

 

Thanks. I was thinking it sounds like the common BCM issues.
