Buick and Chevrolet dashboard display may go blank medium
A software glitch in the module that runs the digital dashboard can make the screen behind the steering wheel go blank. It may happen when you start the vehicle or while you are driving. When the screen is blank, you cannot see how fast you are going and you will not see warning lights telling you about problems like low oil pressure or a brake issue. The fix is a free software update, done either at a dealer or sent to the vehicle over the air.
