Mazda rx8: sir, I have been the sole owner of this vehicle since the day I purchased it, and each time I'm on a business trip for one week or more, the car has to be towed for services. Either for flooding out or recharging the battery. Last month I bought an advertised device, car md, to help diagnose the problem and it indicates there's an electronic sensor issue, which mazda choose not to admit. My car has less than 24,000 miles on it and has been a living nightmare since I purchased the vehicle.
