I have a 2014 iTouring 6 that has developed a rattle in the left front of the car. Might be suspension, but not certain. It can be heard when there is any irregularity in the road and has gotten worse over time. Car has 45K, all original suspension components, nothing has been replaced or worked on. I've bounced the car and can't duplicate it. I've checked bushings, lug nuts, strut mount nuts stuff on that side under the hood but found nothing. Debating if dealer is my best first option or just a local shop as dealer isn't that close. Thanks!
