2007 Acura Tl battery sometimes drains completely if the vehicle is not used for 2 or more days (nothing left on). Some electronics must not be shutting down and continue draining the battery. Dealer claims it's normal that if you go on a trip your car might not start if it hasn't been used in a few days which is preposterous. Afraid to leave car at airport when traveling. I've had to bring the vehicle in twice in the last 12 months. First time they replaced the battery; last time they could find nothing drawing power. Web search reveals lots of people having this problem. Dealer admitted they're replacing lots of batteries - but that doesn't fix the problem.
