I have a 2010 Buick Lacrosse with just over 102,000 miles. It has been generally a great car, but just recently whenever I turn off the car, the Radio automatically returns to 90.5 FM, which is the First pre-set button. That is not a big deal, but since the time has changed, I set the clock to "fall back", following the instructions in the Owner's manual, and whenever I turn the car off, it resets to the time one hour ahead. This is very annoying. Does anyone else have this problem, or heard of this problem? I have not brought it to the Dealer. Any help?
