What owners report

Massive safety liability here. My 2019 Audi A6 was on the highway traveling at 75mph on 4/25/2023 at noon when with no prior warning, all of the electrical systems started failing rapidly. In the course of 90 seconds, there was an electrical malfunction warning, quickly followed by malfunction warnings for steering, brakes, and cascading shutdowns of all systems like the transmission, ABS, Collision Warning, Lane Departure, lights, hazard warning lights, instrument screens/clusters, HVAC, windows- literally everything. A complete failure of every component and safety system while driving highspeed is extremely dangerous. Had this happened at night, I would have been bricked in the middle of the road without headlights, hazard lights, airbags, etc. The car had to be towed away to the dealership and is available for inspection. …

2019 A6 · Apr 2023

This 2019 Audi A6 purchased on Aug/2020 brand new from an authorized Audi dealer, after several complaints on its breaking behavior it has been diagnosed at the dealer with "Bended Brake Discs or Pressure Plates". Vehicle has been used as a family car an driven in a normal way only by myself. The odometer currently reads 32,165 miles. I believe that the material or workmanship were/are defective. The safety issue is in relation to the longer distance it takes to break and the extreme vibration on the steering wheel when going over 55+mph. No warning messages or any other vehicle feedback is received.

2019 A6 · Jan 2023

At high speeds (around 65 or more), when I apply the brakes I can sense some vibration in the brakes. I mentioned to the dealer that the brakes are not smooth as in my other cars. I was told, it is because Audi is a "performance car." Now I know that it is just poorly built.

I am writing to formally file a complaint regarding persistent mechanical failures and safety concerns with my 2014 Audi A6, VIN: [redacted] , which have resulted in significant repair expenses, inconvenience, and potential safety hazards. Despite having the front brakes and sensors replaced in the previous year, I recently experienced brake warning lights and related malfunctions. According to the most recent service report from Audi Bethesda (Repair Order [redacted], dated May 9, 2025), it was discovered that the incorrect brake pad sensor had previously been installed and that connectors were not properly secured. Additionally, the repair team found further issues with the ABS sensor and rear brake pad sensors-indicating an ongoing pattern of misdiagnosis and improper installation by authorized service providers. …

2014 A6 · Apr 2025

A few times when slowly gliding to a stop (red light or stop sign) when stepping on the brake pedal it seems to go to the floor and needs to be pumped in order to stop. It's a scary situation. I cannot make it happen. It didn't seem to happen until I had the brake fluid changed during routine maintenance at Audi. I reported the problem to dealer where the work was done and they said that they redid the fluid change but the problem has re-occurred a couple of times. Also, it seems that when sitting in the car with it idling I can just about press the brake pedal to the floor.

2012 A6 · 110,000 miles · Nov 2019

I purchased this car in January of 2017 from Audi (international autos) of orland park, illinois. The car was a cpo vehicle, and we also purchased Audi care. We live in central illinois, and we drove the car home 2 hours from the dealership. During the drive, we noticed a vibration when braking at highway speeds. We contacted our local Audi service department, grossinger motors. The brakes were warped, causing the vibration. They identified that the car had recently had the pads and rotors replaced at the orland park dealership and were still under warranty. Rather than having us make the four hour round trip, they replaced them again at their location. Since then we have had 2 more sets of rotors replaced, and the car is back in the shop for the fourth set. The warranty covered the first 3 sets, as they had to be replaced within only a couple thousand miles of each other. …
