We had this happened twice. The first time the vehicle would not start after it occurred and had to be towed in, when they examined it they could not find any problem. It re occurred a few days after we got it back, but it went out after the car turned on that time. We have also had two defective stereo systems, a faulty rear hatch door and are getting frustrated

ISC stands for Idle Speed Control. The details of the procedure are in the TSB at the following link:

I feel (just a feeling) that my 400H's engine runs too frequently and the gas mileage is only about 23 but don't have any gear chattering. The car was at dealer's lot for a couple months before deliver, won't be surprised if they jumped it but did not do an ISC. Do you know what the correct idle speed should be or any way to find it out?

P.S. the gas mileage at 23 is a fact

How is the message saying "maintainence required soon" or "maintainence due" reset or turned off? I do my own maintainence. (Oil, filter, brakes, etc)
