Thermostat, Water pump and now the engine.
This car has proved that I will never purchase another from this manufacturer. It has given me more trouble than it is worth. Beware and stay away!!!
You state all of these issues with your vehicle, yet you don't mention mileage. That information would lend a lot of credibility to your review, as well pinpoint at what time/mileage these issues occurred.
To add... stating engine size.. makes all the difference in the world.
