Well, my car is loosing its mind. Yesterday afternoon I get home from work, and notice the rear of the car is about 4" higher than normal. I had to go to the store, and drove fine there, but still looked a little high on the left rear. Got home and parked in the garage, was completely level again.

This morning I drove to work and it's fine. I guess I should be happy that my air struts are not leaking at least...

Not considering the battery as the issue--replaced it this summer and I don't make short trips in the car so no reason it shouldn't be fully charged. No warning messages or lights. Don't think my code reader will pull B or C codes, unfortunately.
