POWER TRAIN:DRIVELINE:DRIVESHAFT
Subaru of America, Inc. (Subaru) is recalling certain 2023 Outback, Legacy, Ascent, and Impreza vehicles. The center support bolts for the driveshaft may loosen, resulting in the disconnection of the front end of the driveshaft.
POWER TRAIN:AUTOMATIC TRANSMISSION:PARK/NEUTRAL START INTERLOCK SWITCH
Subaru of America, Inc. is recalling certain model year 2021 Crosstrek, 2022 Forester, 2021-2023 Legacy, and Outback vehicles. An insufficient weld may allow water to enter the inhibitor switch, causing it to fail.
