2016 GL350 SRS Malfunction No Start
Wife's car just had a no start problem. 5300 miles.
SRS Malfunction warning (amber), Front Right SRS warning (amber), Parking Brake warning light (Red).
Cranks like crazy but no start - not a battery issue.
Drove all day, parked at her folk's place in the early PM - came out to leave - no start.
Had some fun with MB Roadside Assistance - no show tow after 1.5 hours, had to bail to a meeting, so she goes over this morning - car starts right up. Of course.
It will be over at the dealer today and I've set expectations I need an accurate diagnosis and some kind of assurance they can a) fix it, and b) ensure THIS fault won't happen again.
I know, I know - pipe dream.
But still . . . this car hasn't even had it's first @#$% service yet and already? Really?
Anybody had this happen? Ideas? I'll post service diagnosis when I have it.

Intermittent faulting relay in the panel under the rear seat - had to go back and ask for the part # - written down on a repair order I can't find right now 
Let me dig for it. Threw the shop foreman for a loop but he nailed it, just took time, they pretty much checked everything in the system to pin it down (and had to make it reproduce).

OK found it - from the repair order:
"FOUND F4kG CIRCUIT 15R1 RELAY IN REAR FUSE BOX INTERMITTENTLY MAKING ELECTRICAL CONTACT."
Rear fusebox under 2nd row - yellow relay - only one in the box.
Now - may not be the same issue for you, obviously, but worth a check. Point being they need to spend time and properly diagnose it. Took us 2x trips to the shop to get this one nailed down.
