Roof leak- Cab Lights or Onstar/XM Antenna?

[fjtort2]

I've developed a small water leak on my headliner up by the sun visor latch (driver's side). My truck has cab lights and the XM antenna.. Anyone else have this issue?

Truck is a 2015 2500hd CC 6.0 with 20,000miles

Probably the Onstar/XM antenna, common problem.

 

take it back to the dealer and they will replace with a new one.

Thanks!

I had the exact same thing. My dealership replaced the xm antenna. All fixed now but sucks when I only owned the truck for two weeks.

yeah mine today just started since i have to have oil change and everything done under my maintenance i will have them fix that too.... otherwise truck is perfect.

I've not had that issue yet. Very particular about my truck, does a leak stain the headliner? I wonder if I could be proactive and get replaced before it started leaking? I relly like this truck, and don't want to be looking at a water stain for the next few years if it happens.

I wouldn't worry about it too much, if it hasn't leaked yet it probably won't. Mine did. Didn't do any damage or staining, just an inconvenience and disappointment. But I'm over it now and loving the truck.

Mine leaked twice so far. Dealer will let me know when they can look at it...

_{I never saw any water but my GPS and the compass in the dash display quit working after a 3 day rain. Dealer said water got into the XM antenna. They replaced it with a new part number.}

My half ton is two years old and the onstar antenna started leaking. I am careful not to hit it with anything. When it is off warranty it is about $520 in Canada to fix it. They are held on by plastic clips " that just fail sometimes"

Next time I will fix it for $5 with a tube of silicone.

The good news is the water marks came out with some hand cleaning clothes that I get from Acklands.

I too had this issue. Returned the truck and issue was fixed. However, now the top of the cab between windshield and around lights, is showing rust (rot) spots. Now what am I supposed to do.....

I know this is old post but there is a TSB out about “ shark fin” leaks. 
I’ve got a ‘15 but didn’t start leaking till last year. Out of warranty so siliconed all lights and fin. Still a leak? Come to find out windshield was leaking filled top around windshield with trim caulk.
