Invalid Data Received From Transmission Control Module

…above Threshold, denied torque request signal, ECU configuration mismatch, ECU vehicle option mismatch, output speed sensor, input speed sensor/Correlation, fan 1 control circuit, throttle pedal position sensor switches D and B circuit low, and DTC U0402-00 for TCM immediate repair. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 72,000.

Vehicle has experienced multiple incidents of sudden loss of propulsion, including at highway speeds. Engine revs when accelerator is applied but vehicle does not accelerate, as if in neutral. Multiple warning lights illuminate, including “Service Transmission.” I narrowly avoided a rear-end collision. Diagnostic codes recorded include U0402 (invalid data from transmission control module) and U1003 (CAN communication fault). Vehicle has required towing for one incident and multiple service visits with no permanent fix. This is a safety concern 11/3/25 Loss of propulsion at highways speeds 11/28/25 Loss of propulsion 1/10/26 loss of propulsion at highway speeds

Complaint Summary: I brought my 2015 Jeep Renegade Trailhawk (VIN: [XXX] ) to AutoNation CDJR Roseville on May 17, 2025, for the U90 emissions recall. The catalytic converter was replaced, and the PCM software was updated. However, the U0402 diagnostic trouble code (implausible data received from TCM) remains stored. This code has been persistent and prevents the vehicle from passing California emissions, which is required for my registration as the car was transferred from out-of-state. The service advisor initially stated that the TCM was updated, but later corrected himself and admitted the TCM already had the latest version and was not reprogrammed. I have not been given written…

…Diagnostic codes included P00FD (Battery B state of charge), U145D-00 and U0402-00 (transmission control communication), U0432, U0418, C006A-54 and C2222-68, indicating faults involving multiple electronic systems. My concern is that repeated battery failures may be symptoms of an unresolved electrical defect affecting the electronic shifter, instrument cluster and communications between safety-critical control modules. This raises concerns about potential loss of gear selection or reliable vehicle information. The September 2025 dealership records document a similar combination of stop/start and shifter faults, demonstrating that this is a recurring problem. I request that NHTSA investigate…

On October 8, 2026, at about 7:20 AM, my 2022 Jeep Wrangler (VIN [VIN]) lost gear selection while I was driving on highway 20 at highway speed. The check engine light came on, followed by a "Service Electronic Stability Control" warning, and then the transmission displayed "Shift to P then Desired Gear." Mileage was 23,816 to 23,819. This happened the day after I picked the vehicle up from a warranty repair for the same problem. It is the fifth repair attempt since I bought the vehicle on April 1, 2026: April 8 (valve body replaced), June 22 (TCM voltage codes P1DB9, P1614, U0402), August 25 (stability control warning), and October 6 (control module going offline intermittently, cause not…

…THE FOLLOWING DIAGNOSTIC CODES WERE PROVIDED BY THE DEALERSHIP: P0AB900,P060A00,P279700,U040200. ACCORDING TO AUDI, MY CAR NOW NEEDS A WHOLE NEW TRANSMISSION AND HAS 'BURNED' TRANSMISSION FLUID DUE TO AN 'INTERNAL PARTS FAILURE' AT 70,290 MILES.THE TRANSMISSION REPLACEMENT AND LABOR IS APPROX $27K. I RECENTLY LEARNED THE TRANSMISSION MECHATRONICS WAS REPLACED BY ANOTHER AUDI DEALERSHIP IN AUG 16' AND THE MILEAGE WAS APPROXIMATELY 22KMILES. I PURCHASED THE VEHICLE IN JAN 17', WITH APPROX. 26KMILES. MORE DETAIL IN PDF. *TR

THE VEHICLE WAS DIAGNOSED BY 2 DIFFERENT REPAIR SHOPS WITH THE FOLLOW CODES: U1504, P0610, P1500, U0420, C0051, C212A, U0402, C1246. ULTIMATELY, THE PDC (POWER DISTRIBUTION CENTER) IS NOT WORKING. THERE HAVE ALREADY BEEN SEVERAL RECALLS ON THIS ISSUE WITH THIS VEHICLE AND THE RECALL DATES DO NOT REACH OUR VEHICLES MANUFACTURED DATE BY A MONTH. THE DEALERSHIP IS REFUSING TO COOPERATE AND HELP WITH NOTIFYING YOU OF THIS ISSUE THAT IS AFFECTING MORE CONSUMERS THAN YOU ARE UNDER THE IMPRESSION. PLEASE RESPOND TO THIS IN A TIMELY MANOR. MY HUSBANDS VEHICLE WILL NOT BE USABLE UNTIL THIS IS SETTLED.

…LASTLY, VEHICLE THREW 3 CODES FOR TRANSMISSION SENSORS AS WELL AS EGR (U0402, U0402PD, AND P1DD2) WHILE CASUALLY DRIVING. THIS CAUSED THE CHECK ENGINE LIGHT TO COME ON AS WELL AS VEHICLE TO GO INTO LIMP MODE. THIS CAUSED A DANGEROUS INCIDENT WHILE TRYING TO PASS A VEHICLE. VEHICLE IS IN SHOP FOR ISSUE ON 4/26.

…The vehicle was taken to the dealer where it produced codes: P00FF, P1789, P25A2, U0073, U0402, U0418, U1610, U1643; however, the failure could not be duplicated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 5,000.

…The battery and alternator were tested and found to be functioning properly, and diagnostic trouble code U0402 was identified. I am concerned because NHTSA previously investigated similar coolant temperature warnings, engine shutdowns, and failure-to-restart incidents involving 2019–2020 Jeep Compass vehicles under investigation PE22-013. Although my vehicle is a 2021 model, it is exhibiting similar symptoms, raising concerns about a potential recurring safety-related defect. An unexpected loss of engine power while driving could create a serious collision risk. I am requesting that NHTSA investigate whether the 2021 Jeep Compass is affected by a similar defect and determine whether a safety…
