2018 Audi Q5 suspension problems

“Driving through the expressway a metal noice from the bottom of my car. One of the coil spring was out of the base and the other was broken. As the Audi dealer, the extended warranty doesn’t want to paid due to a corrosion on the bottom of the car. I’m live and drive close to the beach. They gave me thousands excuses to not fix it. My car has 60,000 miles and is from 2018. I was reading that those car may not be coated with special wax for corrosion.”

“The front subframe on the vehicle is severely rusted and corroded through rust. Part of it has fallen off, and the rest of it is badly damaged. A structural integrity, a major safety risk. The Audi Dealer inspected it and confirmed. The car is unsafe to drive.”

“Rear coil springs broke. No heavy duty cycle. 46,000 miles. Spring retention pads dislocated and destroyed. Powder coat anti rust prevention in 90% good shape. No reason for coil springs to break other than assembly defect or supplier material defect.”

“The rear passenger side suspension coil was found broken with a clean break but embedded into the coil boot during a 70k service at the Audi dealer with ~61k miles. No alarming condition of the failure was present, and if it would have dislodged while at speed on the interstate would have resulted in complete loss of control and bodily harm to the driver as well as other vehicles on the road. This was a CPO vehicle garage kept and routinely serviced by Audi, yet they denied any liability and provided no assistance when I escalated to corporate due to being out of CPO warranty by ~2 months. As a result, I had an independent VW specialist shop perform the work, document the observations as if they were to be subpoenaed in the future, and provide me all the parts from the repair (which I still have). The spring coating is completely intact on both rear coils and during the repair process it is evident that the part number has changed from what was originally installed to the current version. The clean break suggests part defect either in design for use or in the spring manufacture. Further investigation on various Audi forums as well as the NHTSA shows this is a…”

“My dealer informed me during a routine inspection that the rear coils springs were about to break and needed replacement at only 66653 miles. Web search revealed many others who have actually failed. Manufacturer will not cover 'out of warranty' repair. As a mechanical engineer with 45 years in the light vehicle industry - 30 in safety - I can say that coil springs do not routinely fail, especially at this mileage. If the do fail at speed I'd certainly expect potential loss of control by the surprised diver.”

“Motor mounts leaking, car at only 45K miles Audi dealer indicates fix will be ~$3,200 Many posts online (AudiWorld discussion forums, etc.) - many drivers encountering issue at even fewer mileage Concerning that there was no warning on vehicle”
