I stopped turned off the car and after restart the indicator was gone and the EVIC said that the Start/Stop was working normally. After about 4 stoplights the message returned. I am wondering if the ground connection to the negative terminal instead of to sheet metal is the problem

Bob - Being that it's intermittent, have you pushed all the fuses and relays down in the fuse boxes? The Power Distribution Center is in the engine compartment. It's the large black rectangular box on the drivers side. Many, including me, have found quite a number of them not fully seated. The Body Control Module is in the interior by the driver's knee behind the small compartment door. I have not heard of anyone finding those fuses loose.
I've seen posts about the message you're reporting but have not read anyone getting a solution. Are you also getting the (A)! icon in the EVIC. The owners manual says to take it to the dealer.
On the installation method, the owners manual cautions tapping into the vehicle's electrical system. The safest way to do that is to pick up the 12 volts right at the battery, as your installer has done.
