burning oil usually is bad rings or vALVE SEALS either takes considerable man hours to fix so it will be costly . they do sell an additive for that but I have no idea if it works . I suggest you check the oil weekly or even daily , not monthly might save you blowing the motor completely
You may have a clogged heater core, thus restricting the flow of antifeeze in the engine, causing it to over heat. Are you certain that the car is over heating? Have you checked the coolant temperature switch? I would recommend that you run a system flush. To do this, you will need to turn the heater on while the flush is circulating. This will allow the flush to clean out the heater core.
No there has not been complaint's like with the Toyota's. Toyota is involved with Subaru on a few thing's , But toyota uses Subaru technology not the other way around. And the accelerator style levers are different from Subaru's. Sorry to hear about your accident. Have a great day.
The head gasket may be a problem, but it may be simpler, if your thermostat is on the bottom of the engine.
If coolant came out when the thermostat was changed, there should be a screw, probably plastic, that goes into the radiator, or near the inlet hose, at the top. This screw is used to release steam when car overheats to restore the vaccum. Turn car on and let idle to overheating temperature. NOW PROTECT YOURSELF FROM GETTING A STEAM BURN. Turn the screw very slowly until steam starts to come out, don't unscrew all the way or you will loose a lot of coolant all over your engine. make sure the coolant resevore has enough coolant to get sucked back in to the engine or this will take longer. Continue this process until there is no steam coming out, I let mine go until a little liquid coolant starts to bubble out from around the screw. Tighten screw and keep a watch on your temp gage, you may have to do it a couple of times as the coolant forces the air pockets out of the line. If this doesn't solve your problem then I would say check the headgasket.
