The problem did not start until this September, so I had the car for 9 months already. I'd expect that I'd have seen this happen last spring since it was very wet in the Northeast. The flip side is I don't know yet if it would happen when it's wet but warm.
Finding another GS will not be easy up here. They're a bit rare since they are rear wheel drive and alot of people don't like that in the snow.
I am thinking about talking to management, not in the service area, at the dealership about this. I do feel that they are trying to resolve the problem and aren't giving me a run around. I'm just starting to wonder if this is something they can fix. My thought, not knowing jack about cars and ECUs, is that there may be a crack someplace, like a wire or ECU or seal, that expands when it's cold out and allows moisture in and causes a short.
Lastly, I am assuming that Lexus field support are in fact high level experts. Maybe I'm wrong there, but it worries me that even they can't seem to figure it out.
I'm hoping that maybe someone else has seen this happen before and might be able to shed some light on it.
Thanks for your time.
