I just found out today that mazda 5 have the same problem as the mazda 3. We just got ours 3 weeks ago and someone already broke into our mazda 5. Don't know what are they trying to steal but all they took is my prescription eye glasses and left my brand new work boots in the back seat with the box opened (Maybe they are affraid of the work boots will encourage them to get a job and earn an honest living). I haven't even wash my brand new car for the first time and this pathetic thief left me a big dent and crease on the driver side door, and a $300 insurance deductible. So watch out guys and gals don't leave anything I mean not even a tissue box in your car.
