Have a 2017 Laramie CC with 5.7 and 28k on the truck(4wd). When I bought the truck 2 years ago it had 17k on it---I didn't take it on too long of a test drive but on the way home it was pulling to the right---I rotated and changed the tires in all different directions--no change. Took the my local FCA dealer for alignment--they changed it a little and said it was in specs--showed me a printout, etc. still pulled but not as bad---now it pulls to the left sometimes and sometimes it pulls to the right--have tried rotating tires again but no luck--will probably need tires next spring so I thought I would wait until then--and have alignment redone by someone who will fix it by the way it drives and not just by factory specs--but I am puzzled as to why it is doing this--I am not to up on the electronic steering so i need a little guidance---got a new scan tool and was fooling wit it and I pulled a U0126---was wondering if dead battery would cause it--I had to replace the battery about a month ago--Thanks
