The dealership I bought it at sold it certified. I was driving it home and noticed that it had a shake in the steering wheel between 80-110KM/H and then it goes away at higher speeds. The tire pressures are all good. My questions is, could it be ball joints/ tie rods /control arms? if so then that should have been replaced for the certification? the dealer is 3 hours away from my home so what should I do?

Another problem is the key fob. I used the key to charge it (3hours driving) and didn't work. So I reprogrammed it according to instructions of this site. Still not working? Any ideas?

Thanks
