-Transmission and transfer case failed, specifically the splines on the input shaft connecting the two, rendering the vehicle FWD instead of AWD. Parts are not available to inspect as they were returned to dealer. -While the vehicle could still function in front wheel drive, the lack of AWD could be a safety risk in poor weather or road conditions, especially given that the vehicle does not send an error code for this issue. -Problem was reproduced by the dealer, who replaced both parts after a 2-month wait for parts. -There is zero indication that these components failed, no error codes or anything. The car also displays how much power is going to each wheel on the gauge cluster, and displays just as it did when everything worked. The problem can only be noticed when using AWD, so many drivers may not know they have this issue. I experienced the traction control light blinking on hard acceleration due to front tire slip and understeer during turns, but beyond that there was no indication anything was wrong. -The dealer informed me this would be a $12,000 repair out of warranty, which I find unacceptable given that the car doesn’t give any error codes. Many many people may not know their car is effected.
