The fonts are too small on all of the control screens, the infotainment screen and on the various buttons on the dashboard. Many people have to take their eyes off the road for too long to read the writing and symbols. There is plenty of unused background on the screens and buttons where the fonts could be enlarged. Or, perhaps a feature could be designed where the driver could increase the size of the fonts as needed.

Sun roof exploded while driving northbound at highway speed (70 mph) on interstate 84 enroute to butte, mt. In rural Idaho; 1766 miles on new 2017 Impala premiere vehicle at approximate 3:45 pm mdt. No other cars around, no where near overpass, sounded like gunshot in car. Outside air temp around 75 degrees. No evidence of any rocks or projectiles. Some glass chards found on trunk. Internal cloth cover was closed or glass could have seriously injured driver and passenger. Glass chards were captured and retained by cloth cover but fine pieces came through fine mesh holes. Took vehicle to local Chevrolet dealer (butte GM) and was advised this was not a warranty item as no such occurances have been reported to date. Have contacted GM customer service and am awaiting disposition.

Closed the driver door on car, heard a what sounded like an explosion from over head. Discovered that rear sunroof panel had exploded, glass pieces had fallen onto sliding visor panel. Had been sitting stationary in the sun. I took it to the dealer. Without question they said it was a warranty item (car 2 months old). Was told by dealership personnel that this was the second exploded panel they have seen this week on a GM vehicle. While driving to the dealership, glass shards flew off the roof scratching the rear deck painted surface.
