Best thing to do is get it scanned for codes. This would point out the problem for repair. May want to take it to your local trusted garage.


Ran into this same issue with my Lacrosse - it ended up being that a cell in the car battery had gone bad or was going bad. I replaced the battery and all was resolved. I would start by checking your battery terminal connections to ensure they're good and firm. If so, then take the battery and have it tested to verify it's working properly. The other possibility could be that your alternator isn't charging the battery quite right and the battery only recovers after sitting. Good luck!
