This happened to me yesterday on a remote backroad. I came around a tight left hander in 2nd gear and suddenly had a 'low coolant' alarm go off. Coolant was spraying out from around the bottom passenger-side of the radiator, soaking my once immaculate engine bay! I couldn't identify where it was coming from at the time, but it looks in keeping what others have reported in this thread.
The car had about 2000km on the odo when this happened. It is a Canadian 'Base' spec model - I'm not sure of the build date.
It turned into a bit of an adventure to get back to cell reception to call BCAA. I had to hitchhike 30min back to civilization, call BCAA, and then hitch another ride back to the car. It occurred to me after I had hitched a ride that I could have used the SOS button, assuming it uses GPS, but I totally forgot it existed...durr.
The car is at the dealer and I should hear back from them in a few days with their diagnosis and hopefully parts won't take too long.
I'm thinking that this thread should probably become part of a sticky at the top of the subforum. I love this car, but this is disappointing and doesn't bode well for taking it to autoX where warranty issues could possibly come into play. Everyone should check that their rad is secure and not loose!
