I've said from Day 1 that the lack of regular key locks for the passenger door and trunk was a bad idea. From anecdotal evidence I've seen and my own experience, I think there indeed may be problems with the Challenger's battery. I had to have my original one replaced in July (at the time, the car had about 2,200 miles on it). The official diagnoses: A "bad cell." Fortunately, the car had been parked outside and I was able to jump-start it off my Mustang without too much trouble. And fortunately, it was replaced under warranty, as a new battery (which apparently is only available at dealerships) is $152. Plus labor, of course, if you get it installed there.
