My 2013 buick lacrosse loses power
My 2013 buick lacrosse suddenly loses power while driving and then
reconnects.. radio turns off and will restart after a few seconds. Then all
temperature and radio settings are erased. sometimes the car will not
start.once I stop. There will be no power at all when starting. After a minute
or so it usually will start again, but randomly the radio will again blank out
and restart. I have taken this to the dealer a couple of times and they say
they cannot find any issues. What could be causing this?
