Audi A5 Suspension problems by year

2018 Audi A5 Sportback has 16,500 miles only on it. Used for city driving only; never off road. Recently went in for annual inspection and was told that my right rear coil spring had snapped in two and vehicle was unsafe to drive. Took vehicle to local Audi dealer and they confirmed broken coil spring; they wanted $3000 to repair the vehicle. I took the vehicle instead to a local mechanic who did the repair--replacement of both broken right rear spring and one on left side--for ~$1000. Mechanic noted that he has seen and repaired many Audis with similar snapped rear coil springs.

I was driving when the rear of my car began vibrating, then fishtailing and I lost control and hit a curb resulting in mostly forward damage. In reviewing the Preliminary Estimate from the auto-shop and insurance adjuster, there was quite a bit of damage to the Rear Suspension including a broken Trailing arm lock nut, washer, and bolt, as well as the Protector lining, lower control arm, its lock nut and the control arm mount bolt. The broken rear axle components caused me to lose control of my vehicle resulting in forward impact with a curb. My car was deemed a total loss with $28K in estimated repairs.

Audi a5 - 2010 models. These cars come with faulty lower control arms and bushings which results in shaking in driving from 60mph to 70mph. I just bought a brand new car yesterday to be exact, the entire drive home the car shook violently, this type of shaking can and will cause accidents, a full failure of control arms will result in death. Audi has not conducted a mass recall as of yet, I believe they are waiting for a few deaths and a mass protests and intervention from federal government before doing something.
