Battery dying too often

deltalima

I have put a second new battery in my Park Avenue (just standard type). If I drive it around and then park it for more than two days, it won't start. I have to jump it, and even then, I have to let it be connected to the jump car for a little while before enough juice transfers to the buick. Very frustrating! I've never had an issue with batteries until this car. Also, the car hesitates and sputters at idle and while driving. This car has given me more problems than any other car I've ever had!

Sounds like you need to first of all check out the car's charging system. If the system's voltage drops too low, the car's various modules get very wonky and the car may not run right. If the charging system is in order, then it's time to hunt for a parasitic drain of some sort.
