my steering wheel is hard and the car won't turn on, shut off while driving.

Hello, sounds like perhaps the battery has lost it's charge and is not supplying needed electrical power to the vehicle. It's impossible to know with the limited information you've shared, but that's the first place I'd look. Now, if the battery has lost its charge -- the question is -- why? Testing will be required to find out if the battery itself would be at fault, or if it's something else. Beyond that perhaps it's not a battery issue. So, any way you look at it - testing is required. www.repairpal.com/repair-shops
