looking at a used 2015 610 with 9k miles. Noticed in the photos of the drivers lcd that the date and time were reset to 1/1/2012. What would cause this? Dead battery? Removing/replacing the battery? Just don't want any surprises.

Also they said they replaced 1 front tire and not the other which still has 9/32 on it. Shouldn't u atleast replace both fronts at the same time due to awd?
