I started with the wrench but then escalated to the "check engine" light and, in the end, the ominous red "check brake system" light and then my emergency brake light came on. None of it was true of course. But after 7 trips to the dealer with them going step by step and finally, ultimately, replacing the entire electrical harness (8 days), I drove off the lot this morning and saw everything was working perfectly. Tonight, leaving work I drove about 12 miles on local streets and the red "check brake system" light reappeared. They're offering to either buy the car back or give me another one. I love the car aside from all this. They can't figure it out so if that's what you're getting for a response as well, do yourself a favor and call the 800 number and get it started.
