Took our 2012 SRX AWD to the dealer today to determine if the AWD wasn't working, or if it is just a POS in the snow and ready for a trade in w/ 11K miles.
The dealer found it hard to believe the AWD wouldn't go in the snow and never heard of such a problem w/ a SRX, but was good enough to take it for a ride to be shocked to find out we were right.
After putting it on the rack, the mechanic found the drive shaft from the front gear box to the rear axle was broken. Basically, the rear wheels were never enabled when the AWD kicked in making the AWD a FWD. The driveshaft wasn't broken in two pieces, but was slipping inside itself and not driving the rear wheels in the AWD mode. Sounds to me like it wasn't assembled properly at the factory, and the dealer's service dept. wouldn't admit to a factory recall issue.
The dealer ordered a new drive shaft from "down south" and will have it installed in a day or two.
It was refreshing to have the dealer actually diagnose the problem without a battle, and maybe there is still hope for this SRX in the snow.
I'll post back once repaired.
