Add me to this list of failed thermostat housings. I went in because my car threw a CEL yesterday and they said it was the intercooler. Don’t remember exactly what he said but they cleared it and then JUST as they pulled the car out of the garage, the CEL came back on. First mechanic couldn’t figure out what was going on, so an older guy hopped in and noticed coolant and ran diagnostics again. Fortunately for me, I’m at 58850 miles and still covered under the powertrain warranty. They didn’t even seem bothered that the car is modded.
Any idea if this part fails within a year, do they replace again, even if out of warranty?
And no, I didn’t bother reading through all 23 pages of this thread to find that answer to that.
