I took my car to a Buick dealer three times for the overheating and they ended up putting in a new thermostat and still had problems now have coolant loss all over the driveway and have to take it back after over $550 for a thermostat I never needed in the first place

Over heating when in stop and go traffic. Once on freeway, it will go back down to regular temp. Fan not turning on as should. does the fan run by a fuse?

During some recent rain there was some brown stuff all over the car that I thought was just dirt but later my vehicle started running hot. That is when I found a small hose was busted and it was replace. Now there is another leak underneath and it is running very rough. I took it to a mechanic and now I have to replace the water pump. I have had to replace almost everything on this vehicle and something always breaks down.
