2016 AUDI Q5 — Problems, Recalls & Safety Data

I am reporting a defect related to carbon buildup in the Secondary Air Injection (SAI) system on my 2016 Audi Q5 3.0L Supercharged (engine code CTUC). My vehicle has been diagnosed by an Audi dealer with DTC P0491 – Secondary Air Injection System Insufficient Flow, and restricted secondary air flow has been confirmed through Audi-authorized diagnostics. This failure mode is described in TSB 2014569 and TSB 2014665/4. I discovered this when the check engine light illuminated and I sought a diagnostic from the dealer which cost me $249. Audi has acknowledged this condition as a defect in other vehicles by issuing Warranty Extension U19 (10 years / 120,000 miles), which covers carbon buildup in the secondary air injection ports. However, Audi denied U19 coverage for my vehicle solely because my VIN is not included in the warranty extension population. This condition results in increased emissions which impact the environment and which will cause the vehicle to not pass the emissions inspection required for registration. Audi has not provided any technical explanation distinguishing my vehicle from those covered under U19, despite identical fault codes, failure mechanism, and required repair procedure. The repair involves removal and cleaning of carbon buildup in the cylinder head secondary air ports and is quoted at approximately $2,500.

I was driving down the highway and all of a sudden my sunroof exploded. It sounded like a loud gunshot. I got off the exit pulled over and I saw that my sunroof was shattered. On my Audi Q5 2016.

While driving and when parked, a strong odor of gasoline enters the cabin and garage. This poses a significant risk of fire and health hazards from fumes. The issue relates to the fuel system. The vehicle was previously serviced for the 2017 fuel system recall, but the problem has reappeared. This defect puts my safety and the safety of others at risk because it could result in a fuel leak and possible fire. The problem has not yet been confirmed by a dealer during this recurrence, but it has been persistent and makes the vehicle unsafe to drive. No warning lamps or dashboard messages appeared before or during the problem.

Vehicle: 2016 Audi Q5 2.0 Premium Plus Date of Incident: March 31, 2025 I was in a front-end collision at approximately 20–25 mph when I struck a concrete pole. The impact was hard enough to severely damage the vehicle—the pole intruded deep into the engine bay, fluids leaked, and the front end was totaled. Despite this, none of the airbags deployed. As a result, I sustained multiple injuries: Severe bruising across my chest and stomach from the seatbelt A head injury and forehead swelling from hitting the steering wheel Persistent pain in my neck, chest, and abdominal area since the accident I have photo evidence of the injuries and damage, and family members who witnessed my condition via FaceTime shortly after the crash. I have checked both the NHTSA and Audi recall databases using my VIN, and there are no open recalls listed for this vehicle. I was never notified of any safety concerns or service requirements regarding the airbags. This is extremely concerning and I believe the airbag system may have failed in a situation where it was clearly needed. Please investigate this issue, as it poses a serious risk to driver safety.
