Jeep Cherokee service transmission error with locked park brake and recurring 9-speed transmission defects since 2014 on Jeep Cherokee

Some Jeep Cherokee owners report experiencing issues with the transmission and electronic parking brake system, including the appearance of "SERVICE TRANSMISSION" messages on the dashboard, indicating potential transmission problems. Additionally, some owners encounter alerts like "SERVICE PARKING BRAKE" or "Service Electronic Parking Brake," which signal that the electronic parking brake system requires servicing. These issues may lead to the vehicle entering "limp mode," restricting performance until resolved. Furthermore, since 2014, recurring concerns with the 9-speed transmission have been reported, which may exacerbate the transmission-related issues. These ongoing problems underscore the importance of prompt attention to ensure the vehicle's proper functioning and safety.
