hello all! my 2011 maxima interior/exterior lights have started to flicker and sometimes will hesitate or jerk when accelerating. I had a new battery and alternator installed in the fall last year. Recently took it to a mechanic who couldn't find anything wrong since it wouldn't do the things i've noticed every time i drive the car. The lights flicker when parked and when driving, the jerking/hesitating isn't every time but enough to know it's not normal. Any ideas what it could be and am I better off to take it to a nissan dealership? Thank you for any info or ideas you may have!
