Lost Communication With Gear Shift Module

…The warning continued, with stored codes U0103, U1465, U1467, and U11E3. Mall of Georgia Chrysler identified the same codes but again replaced the main battery and service shifter module. The vehicle malfunctioned after those repairs, was returned for further diagnosis, and then suffered this roadway failure immediately after its next release. Despite repeated repair attempts, no root cause has been documented. The dealership proposed replacing another transmission-related module and electrical component but could not guarantee the repair. I am concerned that parts are being replaced through trial and error while the safety defect remains unresolved. Chrysler TSB 21-027-17 Rev. A addresses…

On 2 separate occasions, I lost transmission service to my 2016 VW EOS. 65K miles. While driving, my RPM increased dramatically, and it felt like the car went into neutral and wouldn't accelerate. I came to a slow, uncontrolled stop on the side of the road. The EPC code, check engine light and the gear indicator warning lights were flashing. It was very scary to not have any control of the car. Very unsafe situation. The code reader indicated code U0103 meaning "lost communication with gear shift module". LP and Sons DeLand FL, repaired the vehicle, citing: remove and replace transmission gear shift.

While driving on the freeway the car stopped accelerating and would only rev when gas pedal was pressed. I coasted to the fast lane shoulder and put on hazard lights. CHP had to stop freeway traffic to push me to the side of the freeway. Car eventually restarted and let me put into gear. I drove to Auto repair store and they scanned car. Code U0103 came back: No communication with gear shift module.

Reported to local dealer and corporate office about the issues with shift module not shifting at random, meaning that the vehicle won't shift from park to drive or reverse, and so forth. The local dealer tried to reprogram the software, but the problem still persists. When plugging in my OBD II & DTC readers, code U0103 appairs which translates to "Lost communication with gear shift control module". My concern with this is that I've had this issue while in traffic, which would make my vehicle a hazard. When it comes to the collision prevention system, the system randomly turns on and off, meaning that when it's needed it might turn on, but when it's not needed it randomly turns on. Once…
