2006 Buick Rainier Q&A
2006 Buick Rainier Question: My car wont start after leaving the key in the on position for about an hour.
You will need to charge the battery and test it. The battery is only three years old but could be failing. Fully charge the battery and have it tested. If you don't have a battery charger leave your car attached to a running car with your jumper cables. Ensure the battery connections are secure, clean and tight. - patrick mannion
