Last Friday evening as I was running an errand, every warning light and electronic systems alert on my CR-V lit up simultaneously. There are more than just the usual Check Engine and low oil pressure light (though both of those are on, too): Electric Parking Brake, Vehicle Stability System, Lane Keeping Assist, Adaptive Cruise Control, Emissions Monitoring, TPMS, Electronic Fuel Injection... and a few more.
So, the car went to the dealer's stealer's shop yesterday afternoon and will remain until Monday. I've agreed to pay over $600 to replace the AC control unit (I don't understand what's wrong with it, and the only info I got was that it was a "Critical Item", making me feel like I had little choice or discretion in the matter) but they still haven't told me what the root cause of the Christmas tree of warning lights was, so I'll have to remember to ask when I collect it. I have about a 10 percent degree of confidence in getting a straight and intelligible answer, and truthfully as long as the dang thing works I'm not likely to care since there's damn-all I could do about it anyway. In the meantime I have a loaner Accord sedan. It's comfortable enough, and entirely adequate to my basic needs, but I do find that I miss the more elevated seating of the CR-V. That's why I bought it to begin with.
