Hey everyone, a few weeks ago, I bought an 08 WRX that I am officially in love with (my wife gets jealous sometimes
Everything about the car is awesome, except one thing: After a long highway drive, about 3/5 times, as soon as I'm off the highway and either sitting at a light or driving through town, it'll overheat, the heater blows cold air and I'll have to shut it off and let it sit for a while before I can drive it safely again; opening the hood reveals that coolant is backing up into the overfill and spilling out from there, and it's burned a bit of oil.
I've already brought it back to the dealer twice for service, both times they said there was nothing wrong and they couldn't replicate the issue. The third time (friday) I called, I was unknowingly put on the phone with the owner, who proceeded to be completely disrespectful and tell me I was abusing the car, they aren't a personal pit stop, and I need to take responsibility for the problem; he said the issue was caused by working the car too hard, causing the turbo to dump all its coolant and take in oil which would cause the overheating. (I'm not familiar with turbos, but that doesn't seem like it should happen even if I WAS beating on the car.) He said he had an "eye witness" saying they saw my car, with my plates, and I was weaving in and out of traffic going way over the posted limit. Then he said he was voiding my 60-day warranty.
Some backstory - I work 40 miles from home. Every day at least once, either to or from, this happens. On top of that, I barely ever even let the boost come into play; I typically shift at 2500, set CC for 60-65 and go steady. Gas mileage readout is 24.6/gal.
I'm stuck between two courses of action now: do I take the car back with the video evidence and give them a chance to rectify, or do I go to an actual Subie dealership (I have a warranty through Allstate that's accepted at dealers so cost isn't really a big deal) to have them diagnose and possibly fix the problem and go after the original dealer legally? CT has lemon laws and there's a good amount of legal recourse there, along with civil action that can be taken.
My biggest questions are:
What could cause the issue? Since it's not constant, I don't think it could be the thermostat, right? I'm not super familiar with Subies or performance cars in general, it's my first "nice" car, so I don't know in detail how the cooling system is set up, unfamiliar with turbos, etc.
Is that an actual common issue with WRX's/turbos in general? I wouldn't think so, I know guys with Evos, modded-out Legacys, other sports and rally cars and I've never heard any of them talking about this.
Thanks in advance guys.
