LKicklight - was this ever resolved? Curious as to what it was.
I doubt this is related, but I thought I'd mention it-
Safety Recall N17 / NHTSA 13V-120
Fuel Tank Transfer Tube
2012 (MK) Jeep Compass and Patriot
NOTE: This recall applies only to the above vehicles equipped with a 2.4L engine (sales code ED3) and 4x4 (sales code 5I4) built from October 18, 2011 through May 07, 2012 (MDH 101821 through 050700).
The fuel tank transfer tube on about 20,000 of the above vehicles may have been incorrectly manufactured. When the fuel transfer process becomes interrupted the vehicle is only operating on fuel from the primary side of the fuel tank. Sustained driving during this condition will deplete the fuel in the primary side of the fuel tank while fuel remains in the secondary side of the fuel tank. This could cause the engine to stall without warning under certain driving conditions and cause a crash without warning.
The fuel tank transfer tube located inside the fuel tank must be replaced.
