NHTSA Complaint #11712561 — 2022 ACURA MDX

My Acura service department notified me at my last oil change that they discovered (accidentally) my transmission / transfer case is damaged and is not transferring power to the rear wheels, rendering the vehicle as 2 wheel drive only. This requires a total replacement costing $16,000 +/-. My research indicates this is likely caused by a faulty splined shaft inside the transmission-transfer case assembly used in the early 2022 MDX vehicles.The dashboard info system for SH-AWD indicates that the car IS in All Wheel Drive and there are no messages indicating a problem with the All Wheel Drive. This has not been a problem during non-snow or other slippery conditions, but recent storms have made this a major safety problem for me. The fact that the car sensing system does not detect this problem could cause serious driving danger for unsuspecting drivers. This also prevents Acura/Honda from acting on this issue publicly as owners of this vehicle have no way of knowing the problem exists until it is too late.
