Lost Communication with TCM

I own a 2022 Chevrolet Silverado LTZ Texas Edition with 51,000 miles, equipped with the factory multi-camera system and rear backup camera. The camera images are clear and all cameras function normally, but the forward/reverse guide/trajectory lines no longer appear. When the cameras are activated, a blue hourglass appears in the upper-left corner and the guide lines never load. This is a safety concern because the guide lines help the driver judge the vehicle's path and distance when backing up and maneuvering in tight areas. The loss of this feature reduces the functionality of the factory safety/parking camera system. I took the truck to an authorized GM dealer. They diagnosed a front…

FORD TRANSMISSION PROBLEMS WONT GO AWAY!! TRANSMISSION SHUTTER AND POOR INITIAL ACCELERATION. THE CLUTCH HAS BEEN REPLACED TWICE AND TCM TWICE BY FORD DEALER. AFTER THE LAST TCM REPLACEMENT IN 2016 PROBLEMS CONTINUED AND I WAS TURNED AWAY BY FORD DEALERSHIPS BECAUSE NO ENGINE LIGHT CAME ON.

While driving at highway speed, my 2025 GMC Sierra suddenly began slowing down without warning and lost propulsion. When I pressed the accelerator, there was no acceleration response. The vehicle felt like it was braking or dragging instead of accelerating, creating a serious crash risk in traffic. A warning message appeared instructing me to “Put in neutral and restart truck.” I followed the instruction, but the vehicle would not restart. It sounded like it was attempting to start, but it would not start normally. A “Service ESC” warning also appeared. The vehicle was towed by AAA to a GMC dealership and remains available for inspection. The dealership provided a diagnostic trouble code…

Service Stabilitrak, Power Steering light, Check Engine light. Door locks lock and unlock continuously. Randomly has No acceleration, causes jolting at a low speed. Available for inspection asap. The code “UO101” comes up in a diagnostic test. Overall, the car basically shuts down while driving at no specific speed. Safety of myself and others is at risk because this can cause an accident resulting in being rear ended/collision with car and other vehicles as it randomly happens when driving. I took my car to the dealership on 3/5/25 and expressed this issue and they could not diagnose it as it was not physically happening after I dropped it off to them. They had the car for 4 days and…

I have about 08/1825 had the throttle body replaced on my vehicle which assisted with the problem temporarily. Then the problem started again 09/20/25 the car act like it’s stalling while driving and can’t see what hear the vehicle is in. The car is not getting any signal to the engine as I have been advised the TCM is faulty. There was a code of U0101.

I have been an issue with my auto stop system past 6 months. While driving and coming to a complete stop the auto stop kicks into gear as it should but when I release the gas pedal to drive off it stalls for a about 20 seconds unlocking/locking doors and proceeds to kick into drive gear. I have had auxiliary battery checked and it’s good. Checked main battery components those are good too! No check engine light came on only when I removed auxiliary battery removed to have it diagnosed it did give me a code of UO101 but quickly went away when replaced. Still trying to figure what the issue may be but it’s becoming more and more constant and worse. Dangerous when it happens on uphill and cars…

I was driving the truck when the EPB, service engine, stabilitrac, ECBM warning lights came on, also driving over 43 miles an hour could cause a crash due brake failure This caused the emissions. transmission, & throttle to shut down Truck would not shift out of low gear. It would shift to park but did not recognize it was in park which kept the accessory on running down the battery, the tail gate would not open, and the information system shut down. I got sick and was…

I took my 2022 Jeep Wrangler to my local Jeep dealership for a 21D Fire risk campaign recall inspection and powertrain software update. Car had to be towed to dealership a few days after services were completed, and was diagnosed at dealership, with an offline TCM, throwing a U0101 code. Car was in good working, driving order prior to the recall and software update and is now completely inoperable.
