I have a 2005 Scion XB, at start up the dash lights flash, nothing works, the speedometer or gas gauge. The car runs fine and after about 15 miles or so the dash begins to work as normal. Any suggestions on what it could be is greatly appreciated.

from what I have experienced with mine doing it......happens only when it is under 40 degrees in the morning and stops when I buckle my seatbelt. As far as what the actual cause is.....lots of speculation about corroded ground points and battery issues but no real answers. I don't live in winter areas where roads get salted, car has no corrosion or rust issues and has brand new battery with volt gauge on 12.5 with key on acc after sitting overnight, 14.0 upon startup and stays at 13.8 after car is warmed up. car has no other issues or codes and runs just fine when ignoring the flashing. Ongoing mystery at this point with bunch of people having same issue. There is another thread about it on here.

I have a brand new 3yr battery with a 12/21 sticker on top and a voltage gauge having 13 when starting and 14 while running. car is parked on cement and has no corrosion and/or rust issues. it has 5 more ground points than it came with....additional body ground, alternator, head, block and fuel...
