A week ago I started driving my 2008 Saturn Vue and was on the road for about 2 minutes and noticed speedometer and tach ware not working. Noticed low tire indicator and door ajar indicator and a couple of others. Continued driving and the radio went off. Drove 10 miles to home and turned off the car. Restarted it and everything seemed to work with door indicator on. Opened and closed passenger door and all was fine. Drove it with no problem. 2 days later drove 60 miles and when the car was parked and the lift gate was opened the rear wiper took one swipe. Did it again the next day, so I turned on the rear wiper and seemed to stopped that problem. Haven't had any problems since. Anyone know what is going on?
