Q: U0121 can abs brake unit all dash lights on stalls in reverse

ABS control unit failures are pretty common on these cars, and cause several warning lights to illuminate when they fail, as well as set faults in almost every control module in the car. Based on the information provided, it’s very likely this is whats happening to you. A qualified technician, such as one from YourMechanic, can verify the diagnosis of the ABS problem. As far as the fuel gauge issue, this could be caused by the faults set in the instrument cluster control module, so I would suggest clearing the faults in all the modules after repairing the ABS issue, and see if the problem still exists after. If it still exists after, it could be a problem with the fuel level sensor. And finally, as far as the windows buttons go, it sounds like the car lost voltage at some point, and the window motors lost their learned positions. This is simple to fix, you just need to reset the window positions. You do this by holding the window button up until the window is closed, then let go, then immediately pull up on the window switch again for 3 seconds. Do this to each window. Now the one touch feature should work.
