after three days working, last night my advisor called me in to pickup. however, when i was there the car is not there. My advisor went in, then got back to me ten minutes later, and told me the driver side window will not rise up. they need more time to fix it. OK then, I drove my loaner back home, and left my truck one more day.
this morning, I got a warning from FordPass, "POwertrain malfunction/reduced power". Then called in, my advisor told me that the car was experiencing a whole self testing, which could generate a false warning.
Is that true ? a self-testing could give a powertrain warning like this ?
any suggestion ? really worry about Fixing a little error result in a even worse fatal problem .
