Computer? Electrical?

Leigh

Okay, so I have a 2006 Buick Rainer V6. I have owned this car for 7 years and it has only 75,000 miles but I swear the thing is possessed. Recently the dash board started to light up like a Christmas tree. When this happens and I go to park the car, it barely wants to start. This has randomly happened driving down the road, sitting at a stop light and even waiting in line at the bank. In the past year I have had the alternator replaced twice, codes read multiple times and fixed what the codes said was the problem. I really got used to having the check engine light on. The car has left me stranded with a dead battery several times in the last week. My check engine light was on again this week and my husband plugged the code reader in and it said there were no codes. ARGGHH! I feel like Charlie Brown trying to kick that damn football. I am having a love hate relationship with my car. I am thinking it may be the computer. Any suggestions and advice would be welcome. (I know, maybe a stick of dynamite)

Have the battery been replaced? A bad cell, a bad post, can cause a voltage drop which turns on lights.

When you say it does not want to crank properly, that would be the first thing to come to mind.
