Computers have often been blamed for problems that are not within the computer, but in the sensors and actuators and wiring that are connected to the computer. People may be misled into thinking the computer was repaired, when it was really something else. Could that be the case here?
Repairing a computer is probably something a dealer or other mechanic wouldn’t do - unless it’s performing an “update” - which might be the case here. Do you have more specific info on what was done, and who did it?
