Well my 07 GP hasn't given me any trouble up until this point. At some points it feels like my car is rolling in mud, mostly on the highway when I'm doing like 50 and I try to speed up to pass a car. I hit 58,000 miles today and i have a warranty up until 64,000 miles. Now I don't have much experience with warranty companies but I hear they only replace something when it fails. Now it sounds like a transmission problem (I hit the same thing with my Ford Focus) but I'm not sure if they will fix this problem now or I'll have to wait til the thing won't move at all. Anyone got any tips? Also, has anyone tried extended warranty companies like the ones on TV? If I can't get some protection for my internals then I might consider trading her in.
