I just bought a brand-new 2012 WRX . While driving it home from the dealership, I was about 5 miles down the road. All the sudden the dashboard lights up like a Christmas tree, all the warning lights came on and the speedometer starts jumping around, but the car still ran smooth. I drive it back to the dealer; they said it’s probably a loose fuse it would take a minute to fix. 30 minutes later the service manager comes over and tells me it looks like it’s probably the alternator and going to take a week for the part to come in. Anybody have any ideas and/or do I just tell the dealership to order me a new WRX instead?
