Two month old battery went dead. Discovered water surrounding the battery and soaked all under carpeting on floor boards. Warranty is expired and since I am a widow on fixed income can not take it to buick as they charge exorbitant prices for problems that should be covered and not happen. Aaa driver said there appears to be a seal someplace near battery that has come off letting water come up through the underside and collect around battery .

My enclave 2009 was caught fire when it was parked stationary in a garage at 9:40am on 5/30/2016. The fire started from the right front of the vehicle, which results in the whole car totaled. Me and my family have been suffering much from this event. It's hard to believe it happened to our vehicle. This vehicle has low mileage (about 30,000), well maintained by us and gm shop in the past (all the records are available in gm system). On 5/31 we reported to gm with detailed information and requested an investigation. On 6/2, customer department contacted me, stating that they don't care about the cause of the fire and they don't involve in an investigation as we have our insurance covered. I told them no matter our insurance company initiates an investigation or not, as the manufacturer, gm needs to check this vehicle and take responsibility and improve its product if there is a deficit in gm engine. However they still asserted that they don't take care of such case. I have kept the record of our conversation in case needed. It's an unhappy experience. All the evidence we got so far suggested it's the problem of the electronical system/engine. We don't want it to happen to other people. We hope gm to have someone to initiate an investigation asap.
