Coolant leaked out of the plastic connector in the head and the engine overheated, the fan seized, the head warped and everything else let go: rings-lifters----
Not impressed by the concep and who design that stupid engine?
The fan is a b--- to remove and that engine is the worst to dismantle. no wonder the discontinued the model...

My car always wants to overheat so your always checking the coolant level. I couldn't even drive home(witch is 14 hours) on the Interstate without having problems. So I hooked my fan cable up to my battery so the fan is always on. When you turn your car off though it makes a funny noise like your car just died but its not hurting anything and its worth it in the long run.

The cooling system is just crap. GM thought they had a brilliant idea for a new overflow tank. It doest have a traditional radiator, just a tank. The coolant doesn't last. Must check coolant everyday to keep it full. The fan doesn't work. The thermostat lasts about 3 months. We have replaced the overflow tank/radiator cap. The cost for this problem is ongoing, because we keep having to buy coolant and thermostats. Not sure if problem will ever go away.
