Two problems related to battery have been reported for the 1996 Buick Lesabre. The most recently reported issues are listed below.
On 2 separate incidences, the battery leaked onto the cable & left me stranded. I was told that this never happens & it happened to me twice 2 years apart. The first time my car was towed to a different dealer & they tried to charge me even tho the car was under warranty. It happened again this mid-summer and I had to pay for this repair and the battery company said that the dealer was at fault for the way it was installed. (too tight) I was given a royal run-around.
Consumer states battery exploded, and requesting assistance from manufacturer.
