2020 Jaguar XE Powertrain & Transmission Problems

While driving on the highway at normal operating speeds, the vehicle suddenly lost power, and the accelerator pedal became completely unresponsive, preventing me from maintaining speed or safely exiting the roadway. This created a severe safety hazard, as I was unable to maneuver or pull off to avoid fast-moving traffic. Immediately after, I attempted to shift the vehicle into “Park,” but received an on-screen message stating that the transmission was not in Park, even though the shifter was physically in the Park position. The gear selector became disabled, and I was unable to shift into any gear. Despite applying the emergency parking brake, the vehicle continued to roll on its own, presenting a serious risk of collision or injury. There were no warning lights, messages, or alerts prior to or during the failure. I had no indication that a critical fault was occurring. The vehicle was later towed to a dealership. Upon inspection, a certified JLR technician discovered faulty wiring in the gear shifter assembly, which had caused a short circuit that disabled the gear selector, the Transmission Control Module (TCM), the Engine Control Unit (ECU), and the gearbox inside the transmission.
