“My 2018 Jeep Cherokee Trailhawk is subject to FCA Recall 01C/NHTSA 25V-011 for two-speed PTU failure. I have experienced 3 serious drivetrain events requiring towing. In April 2024, before the recall was announced, the vehicle suddenly lost acceleration while entering an interstate/on-ramp, with loud grinding/revving and jerking.
