I recently took delivery of Roadster 1190 (2011 2.5) and it's beautiful. There's a couple things I'm going to need to do to get the car perfect (glass top is on the way, a better detailing, etc.). But for now, I'm very happy. The battery seems to have good capacity for a well driven car (25K) and it feels good and solid (albeit some small squeaks here and there). The moment I got the car home and plugged it in, I then received this warning. I had been driving the car very moderately in very pleasant weather - 75 degrees. Again, this came up shortly after plugging in and and charging in my high-rise parking garage with a normal 110 plug. This is the only charging option I will have for the foreseeable future. I sent a note to the several service contacts that I have - and got quick responses even on Independence Day (great service!). The technicians said that it was nothing to be concerned about. However, I'm concerned when someone breaths in the direction of my car! They also recommended that I move to another outlet (not an option) or get a NEMA 14-50 installed (not an option). He said that "It means your power dipped while charging" and asked "If you clear it, what happens?" I let him know that the car seems to keep charging and there's really no apparent issue from that point forward. Although, when I return to the car hours later, the same error is on the screen again. Also - the fan is running in the back of the car 100% of the time while it's charging. Actually, the only time it's not running is when the car is not being charged and is sitting in the shade after being there about an hour. . . The technician also said this (the fan running like crazy) is nothing to worry about - but I'm worrying. I don't like that many moving parts going on in a car; and it's worse while they're moving while the car is just sitting there. That's one of the reasons I wanted to get away from ICE in the first place. . . Anything you guys have? I searched all over the forum and can't seem to find this error. I just don't want to be damaging my car as I go when this is my only option for actually charging. Thanks so much in advance everyone!
