Default My STI Does NOT like the cold weather!!!!

Well it was 17 balmy degrees when I left my house for 11 hours of driving. After the 1st hour on the highway the cruise control kept turning off of the set speed. The cruise light stayed on but just lost its setting. Then I smelled coolant. I can't find a leak anywhere but it seems to be comimg from the radiator cap but the cap was still cold. It seemed that the thermostat didn't open because it never got warm enough? My mileage was down to about 20 mpg after the first 4 hours of driving. It almost seems like the ECU was running as if the car was just started and never got to operating temp although the water temp seemed OK. Oil temp was very low though. After 8 months and 50K miles I'm not so sure about the reliability of this car, I've already had to replace a few parts. Oh well. My RS ran great for 160K with not a single problem.

I don't know the specifics on the WRX/STI cruise control set-ups, but my 91' Bonneville SSE used to have cruise issue's in the colder weather as well ... It would shut off on declines ... Turned out to be a vacuum leak ... Replaced a couple vacuum lines, and never saw it again ... Although I can't see a new car having bad vacuum lines already, maybe one's loose or not seated properly? ... Hope this is helpful ...

What was your temp gauge reading? If it was in the usual spot (just shy of in the middle), then your thermostat is fine. If it was hanging around the Low mark, then you need it replaced.

Something isn't right somewhere....and the thermostat is the place to start looking, I think.....you never reached proper operating temperature, I think.

I'd suggest getting somebody to ride with you on one of these road trips, with a deltadash. See what the coolant temps actually are.

Cruise control - I agree, vacuum leak someplace.

Thanks for the info, I'll look for loose vacuum hoses, I thought the STI cruise was all electronic. As for the temp, I was going by the oil temp gauge. The water temp gauge was fine but those aren't all that accurate. 875 miles today at $.365 per mile = $319.38.

It is electronic, but it bases its electronic control on what the sensors are seeing. If something is outside of norms, it may be thats its dropping you out of cruise.

Honestly, I'd just log the heck out of the car, see if you can identify what those conditions are.

I wanted a beater but when driving 800 miles in a day I wanted something reliable also, usually can't get cheap and reliable.
