I have a 2005 HAH with 95,000 miles. The IMA and engine lights light up, go off after a few weeks and come on again. I'm trying to decide whether I'm going to get it repaired or move on. I love the car and have had few problems over the years. My question is whether replacing the battery is all it needs. The IMA computer isn't working right, the gas milage per gallon doesn't work. I'n not sure a new battery would fix that or if the IMA system is bad, too. Any advice?

thanks,

Richard
