Console displays occasionally do not light up. Dealer never could find problem. Remote entry system stopped working. Was out of warranty, cost about $600 to fix. Shortly thereafter car would not start. When ignition key was turned there was absolutely no response. If you messed with the shift lever and ignition key for a while it would finally start. Another $600 to replace ignition switch and some sensors. Traction control light comes on for no reason. Dealer can't find cause. Electrical/computer system very unreliable. Lots of road noise, very poor sound insulation. Just traded it in for a Ford. I'm done with GM.
Good gas mileage for a full size car.
More reliable electrical/computer system needed. Better sound insulation.
