It sure does happen to other makes/models with same shift motor actuator. I'm not smart enough to know if that particular issue is sufficient for a recall of all makes and models using that actuator. Its not as if the problem is an unknown one. Here's a copy of a review (couldn't find a date) indicating that the issue was known. http://australiancar.reviews/reviews.php#!content=recalls&make=Mazda&model=BT-50&gen=570 Mazda BT-50: 2H, 4H and 4L not engaging For Mazda BT-50 vehicles, there have been reports of: Owners having difficulties engaging the various drive modes (i.e. 2H, 4H and 4L); The 4x4 and 4L lights staying on when 2H is actually engaged; and, When in 4L, the speedometer providing a reading that is around half of the vehicle’s actual speed. These symptoms may be caused by: Failure of the shift actuator on the transfer case (i.e. the 4WD actuator motor) not working properly; Movement of the position sensor within the 4WD actuator motor. For this problem, loosening the three T-15 Torx screws on the actuator motor’s position sensor plate, swivelling/adjusting the plate and re-tightening it may fix the problem. Some owners, however, have found that this only provides a temporary fix and that the shift actuator eventually requires replacement (as above); and, In rare cases, corrosion of a relay attached to the transmission loom. The same problem was listed for Ford PJ/PK models using exactly the same wording. To me the cause of the problem is failure of the water proofing. When I pulled the motor itself apart there was water still inside and rust everywhere. I'm certainly not a beach or saltwater fan. The taste test was fresh water. Anyway, cleaned all of that up with super fine steel wool and generous amount of lanolin spray. Brushes looked ok. Bit tricky getting the rotor back into the motor (wants to stick to the magnets in the case) but figured it out in the end. The waterproofing rubber ring wasn't water proofing properly so had to pull it out (its looks effective if put in properly) and re-insert it. Time will tell if I got it right, I guess. Its the unconscionable conduct of Ford and Mazda using market share (and probably market influence) to gouge that's the real problem (to me anyway). THAT would be an issue worth taking to the ACCC. Seeing what the ACCC response is would probably be a reasonable indicator for possible success/failure of a class action.
