It is equipped with a function that kills the engine when you come to a stop and you can turn the function off with a button on the dash. I really dislike having the engine stop like that so I always turned it off. Well, the first battery lasted a year, the second also lasted a year. The battery that starts the engine when the function is turned on is a lithium unit and it also had to be replaced. The 3rd cranking battery only lived about 10 months and the dealer refused to warranty it. Before the batteries would die the car would start shifting badly (electronically controlled tranny). I had to pay for the last battery out of pocket. I decided that would be the last time. Just for sh**s and giggles I decided I would allow the stop/start function to remain on, the default position. Well, we are well into the second year on this set of batteries with no indication of imminent failure! I cannot explain why it is but it appears that leaving that switch turned on did the trick. It took me some time to get used to the engine turning off every time I come to a stop but now I don’t even notice. If your Liberty is equipped with this feature and you disable it as part of your pre-drive routine, try leaving it in the default ON position. It worked for us, it might just work for you!</p></blockquote><p></p>
