I am new here, so forgive me if this question has been asked before, and direct me to the correct information.

My daughter recently bought a 2008 3.5 SE which has about 198,000 miles on it. It sat a couple of years before she bought it, but after replacing the radiator and fan, the car is running great and does not seem to have any problems worth noting. However, all of the dash warning lights - charge indicator, ABS, oil, check engine, etc. - are on. Any idea why? I am her personal mechanic, so it is in my best interest to make sure she and the grandkids are in a safe and reliable vehicle.
