well.. looks like they're not willing to cover it because it's the "coolant control valve" that's causing the thermostat to stay open...

Pretty pissed right now.

My car literally had 39,500 miles on it when this problem occurred.

Coolant control valve seems to be electronic.. really starting to think the repair done on liftgate could be affecting this.

1 day after my liftgate was repaired, rear tail light burnt out, and the lights flickers inside my car at a separate time, but just after the fix.

 

Mazda is going to cover 80% of the repair, which is about $600, so I will have to pay $120 out of pocket.. I'll take it. Not worth my time and energy to fight for the additional 20%. The rep also told me that had I gotten them to cover it 100% out of warranty, if the new part is defective, Mazda would not be responsible, so by having me pay the 20%, there is a warranty on the new part. Sounds strange. I know.

I still haven't received any information has to how the thermostat differs from the control valve..

 

How'd the tailgate affect the thermostat/control valve? At least they covered 80%, seems good enough.

 

it was a stretch, but the problem showed up soon after my repair, and one of the tail lights burnt out immediately after getting my car back from the shop.
I was thinking that might of fudged up some of the electrical..
