Hello friends i drive a 2015 volvo XC60 T5 lately i have got a message saying Auto Start/Stop service required. as well as another message that comes up from time to time saying battery charge failure. i have contact my volvo approved mechanic and they tested the alternator and the battery. they say my car has no issues. But i know something is wrong, When i turned off the Auto start/Stop my car still feel like its trying to turn on whenever i come to a stop i feel a small shake. My volvo mechanic says nothing is wrong with my car at all. any idea's of what could be going on? was going to take to Volvo dealership but they want 200$ just to look would rather try to avoid that. any answers are helpfull.
