Hi Dave, As you know I have a fleet of Chrysler 300C SRT8s and have been running Chrysler 300Cs and SRT8s since '05. I've experienced your problem before. It is definitely one of the wheel speed sensors but there is no easy way to determine which one. The problem does not throw a trouble code and actually all the functions are still working even though those three trouble lights come on (ESP/BAS/ABS). This issue will not throw the CEL light so if that's on it's related to another problem. The three lights will go out after a few ignition on / off cycles because the problem with the wheel speed sensor will be an intermittent one. I would not bother to do a repair until you are "in there" doing something else like a full brake job THEN you can replace all four wheel speed sensors. Sorry you have not been real happy with your Chrysler 300. All of my cars have been absolutely fantastic. I run them up to about 300,000 miles before flipping them. I have NEVER had an issue with any of them (12 cars so far) and some have never been back to the stealership for anything. Just routine maintenance . . .
