Air suspension system fails in cold weather. Thousands of confirmed cases. https://www.facebook.com/groups/292298311479202 A class action in Canada. A whole business is taking advantage of removing these parts. airdelete.com My air suspension leaked out during a trip, warning lights, vehicle's air suspension dropped to the frame. No suspension resulted in a very bumpy, dangerous immediate driving conditions. Once the drive became bumpy, two hops for every bump in the road. Steering became difficult due to driver instability.
