As we have said before cars today are very complicated, the best thing to do is head right to you certified service center and have it tested with the proper equipment by a certified technician. A warning, if anyone tells you to start the car and remove one of the battery cables to see if the engine keeps running, don’t do it! they may tell you if the engine keeps going that the alternator is good, not so. And even more importantly you can damage one or more of the very expensive computers in your car.
