We have a saturn vue 2005 and in July 2011, while towing it with our motorhome, the car started smoking. We stopped immediately and found that the gears had been engaged. There was a small fire in the engine. Called the tow truck and it was towed to a GM dealer close by. The transmission was replaced and the engine too. Cables were replaced and so forth. We kept getting calls from the dealer as to the progress, then something went wrong and the car would not run. They brought a mechanic in from Houston and after 3 or 4 days he found a mis-connection and all was well. We picked up the car, towed and drove it around every day and all was well. When we got back to California, the car would sit for a day or two then the problems started. If we don't drive the car every day, for long periods, the battery will die. The battery has been replaced twice, the alternator is fine. We are at our wits end, what is going on? No lights seem to be on at night, the car runs great when charged. As you know in order to tow this car, we have to pull out one of the fuses, could it be that over the years this fuse connection is damaged? Please help us figure out this mistery.
