Made an audible clicking noise when the window was down while driving at 10-15 mph. Discovered by a tire change technician. Bushings were visibly cracked and deteriorated.

Felt a "thump" from time to time when braking. Occurred intermittently. Told by BMW service that tension strut bushing was problem. Cost $452.00 to repair as this is not covered by BMW's CPO warranty.

When I am slowing down just around the same time that the transmission shifts from 2nd gear to 1st gear and vice versa the car will jerk.

Slight knock that comes from the front-end each time the brakes are applied or released. Additionally, the steering wheel gives a quick slight jolt or twitch. Repair is pending.
