Suspension

17 reports
“I have a 2018 Audi Q7 3.0L with 86K miles on it. I discovered 1 of the rear coil springs was broke and both rear perches were very rusted. I had a local mechanic, who specializes in AUDIs, replace both rear springs and perches with OEM parts. After replacing everything, the mechanic went to take the car on a test drive. He said one of the new springs broke right away. The spring that broke was in the exact same location as the one that originally broke and it broke in the EXACT same way.”

Electrical system

16 reports
“Left Front side marker light faulty. is the warning on the dashboard - I have noticed there is a recall I believe 2017 2018 for the same part and this is on a 2019 so it's obviously the part it actually says if there's a software fix”

Service brakes

12 reports2 crashes
“Error code for right front side marker light faulty. Light seems to be working. I've had two mechanics look at the car. They can't figure out what's wrong. Error message appears randomly. Brakes are very squeaky. I took the car to Audi and they said it was normal and I should brake more aggressively.”
