2016 Audi Q5 Problems

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.

Audi had Valves and pistons fail on the highway at 75mph on Nov 28,2024 at 117000 miles Had the vehicle since 2021 and 17000 miles. Complained to the dealerships at the last 3 oil changes about excessive oil consumption. They told us not to worry about it, full aware that they had lost a lawsuit over this very issue. We were never informed about this lawsuit, and now Audi refuses to fix THEIR problem. We are very lucky when the engine blew up that there was no one behind us, otherwise it would have been a major highway accident. Now Audi wants $18,000 to replace the engine.

Driving on May 20, 2026 near my home in Florida, power steering assist failed suddenly making it very difficult to steer. Red light on dashboard lit up indicating steering failure. According to a search of the NHTSA records, this is a known issue with these cars. (NHTSA Campaign 15V452000, Audi Action Code 48M1. If I had been on a highway or busy street, the sudden failure would have likely caused an accident. The car was towed to Windemere Automotive in Naples, Florida. The steering rack was defective and replaced, at a cost of $4700. Letter written to Audi of America, INC about this incident. I received no response. This event occurred with no warning, an no previous hint of a steering problem.

Back in 2017 there was a recall on my 2016 Audi Q5 regarding the fuel pump. Audi's solution to this recall was to replace the fuel pump if it had any cracks, but if there weren't any cracks their protocal was to just put a protective shield on the fuel pump. Since my car was only a year old, all that Audi did was the protective shield. A few weeks ago, my car started smelling like leaking fuel. After a couple days I took it to Audi since there had been a recall. My car has less than 63,000 miles on it and according to service persons that have looked at my car, it is in excellent condition. However, Audi service told me that because the protocol for the recall was performed on my car back in 2017, there was nothing they could do except replace my fuel pump and charge me for the work done. The noxious fumes were so bad that I could not drive my car without having all the windows down. I found out that when the intake fuel pump goes bad, so does the high pressure fuel pump and both have to be replaced along with the pressuer sensor. This cost me $2,700. After getting my car back and driving it less than 25 miles, I was stranded on the road and had to have my car towed back to the shop with a broken steering rack and a dead battery. Come to find out, the steering rack is another issue going on with Audi vehicles. These are very serious and life threatening situations, especially with noxious fumes from gasoline which is highly flammable. Audi needs to reimburse me the $2,700 for the fuel pump replacement cost that I would not have incurred if my fuel pump had actually been replaced in 2017, instead of a band-aid being put on it, which was negligence on Audi's part. By not replacing the fuel pump, I ended up with a gas leak in my car, my car dangerously breaking down in the middle of the road and having to be towed and ultimately a very costly repair for me of which Audi doesn't want to own any responsibility in.

On [XXX] at around 8:55-8:59 I finalized the paperwork for a purchase of a car, received the keys, drove out of the dealership and by 9:02 the check engine light came on and the car shook. On [XXX] at around 2:22 pm, as I was driving, the car shook, pulled up to red light and the car would not move. It shook, rattled and died. The EPC light came on. I owed the car back to the dealership. I noticed that parts of the car next to the muffler and the tailpipe were belong held together with making tape. I received a call from the dealership from Tony. He said the car was fixed by the owner. No clear verification that the dealership owner is as trained or licensed mechanic.

1) The Electromechanical Steering Unit is producing an error light on my instrument panel, and yes, it is available for inspection upon request. 2) If the steering unit fails, the results could be catastrophic for myself and others. 3) Yes, in multiple cases/places. There is a recall for this part in Canada. Also, an extended warranty was granted by Audi of America for this part for numerous 2011-2016 Audis, including the Q5, so long as they are under 10 years / 125,000 miles, which mine is. However, when I have gone into my local Audi and also called Audi of America, they said my vehicle is not included in this extended warranty and there is no recall on the part. 4) Yes, my car has been inspected by my local Audi. 5) Yes, the warning lamp continues to be displayed. No other symptoms have occurred.

I am reporting a safety issue involving my 2016 Audi Q5. The vehicle previously underwent recall 20Z8/20W9, which addresses fuel pump flange cracking that can cause fuel leaks and fuel vapor odors. Despite this recall repair being marked as completed, I am now experiencing a strong gasoline smell inside the cabin. This appears to be the same condition the recall was intended to fix. When I called the authorized Audi dealership (Audi San Jose), I was told I would be responsible for diagnostic and repair costs because the recall had already been completed and is no longer covered. I believe this indicates that: The recall remedy may have been ineffective, or The defect has reoccurred This presents a potential fire hazard and safety risk. I am requesting that this issue be reviewed, as it appears the recall did not adequately resolve the safety defect. Date issue first noticed: [04/27/2026] Mileage at time of issue: [101k] Thank you.

Paid for fuel pump when should b covered on recall

The side assist went out and I had it replaced at the dealership. I paid out of pocket for this cost. The engine had been burning oil then started causing problems while driving prompting me to take into the dealership. I was informed that the engine is in backorder and it’s been a year since I’ve been waiting. I purchased the car used with around 79,000 miles on it around February 2023.

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.

THERE IS A LEAK FROM THE PANORAMA SUNROOF INTO REAR SIDE CABINET OF THE VEHICLE. THERE IS ALREADY A RECALL #17V001000 BUT MY VEHICLE IS NOT ON THE LIST EVEN THOUGH THE ISSUE IS IDENTICAL TO THE RECALL DESCRIPTION. THE LEAK CAN POTENTIAL CAUSES DAMAGE TO THE SIDE REAR AIRBAG SO IT IS A SAFETY CONCERN FOR ME. HOWEVER, THE CAUSE IS REALLY A DEFECTIVE DRAIN HOSE CONNECTING TO THE SUNROOF DRAIN THAT IS NOT SECURELY ATTACHED OR MAYBE DEFECTIVE.

FIRST OF ALL I AM A RETIRED POLICE OFFICER WITH 35 YEARS OF SERVICE..TWENTY FIVE YEARS AS A CERTIFIED ACCIDENT INVESTIGATOR. MY EXPERIENCE WITH SAFETY HAZARDS IN REFERENCE TO MOTOR VEHICLES I HAVE CONCLUDED THAT THE SIDE VIEW MIRRORS ON THE Q5 (2016)ARE WAY TOO BIG AND OBSTRUCTS YOUR VISUAL FIIELD ESPECIALLY THE DRIVERS SIDE MIRROR. ON SEVERAL OCCASIONS THIS BLIND SPOT ALMOST INVOLVED MYSELF IN A VEHICULAR ACCIDENT.

I was pulling into a parking space at approximately 5 mph and the car unintentionally accelerated causing me to jump the curb, go over a grass median and land perpendicularly onto a one-way active road. There were trees and other items on the median I could've hit had I'd been pulling into a different parking space. I also could've hit cars on the road. I quickly got off the road and parked the car.

In short my front right brake caliper failed. To be clear, brake fluid seeped out of the main 2 halves of the caliper. After some investigation there appears to be a recall on this issue on 2017 models and newer but not on my 2016. Per my mechanic this failure is rare and unusual and could have been catastrophic. The brake light warning did come on, but the amount of fluid that seeped was significant in that even 1 day after my light came on and driving a short distance to the shop, almost all of my brake fluid had seeped out.

I PULLED INTO A PARKING SPACE AND PUT THE CAR IN PARK. AS I DID SO, THE ENGINE REVVED AND THE CAR LURCHED FORWARD STRIKING A TREE. THE AIR BAGS DEPLOYED AND THE CAR WAS WRITTEN OFF BY THE INSURANCE COMPANY. I HAD NOTICED A COUPLE OF TIMES BEFORE THAT THE ENGINE WOULD REV AS I WAS SLOWING TO A STOP, BUT HAD NEVER HAD ANY ISSUES WITH THE TRANSMISSION.

My Q5 failed inspection due to a rusted subframe, so badly there is a huge hole in it. The dealership sent photos and notes to Audi but the dealership claims Audi denied my warranty claim (12 Year Corrosion Warranty) because it's not a body panel (the verbiage used in the warranty). However, Audi customer service told me it was because the dealership wrote a note that it was due to neglect. This is a safety defect that I was unaware of until now - I keep up with oil changes, have my car inspected every year and was never made aware of the problem until now so how would I be expected to know what was happening beneath my car. I've done lots of research online and this seems to be on the verge of becoming a common issue seen in 2010-2017 Q5s. So much so, there's a law firm investigating it like DiCello Levitt - could be a design flaw, there is a plastic covering known to trap moisture and debris. I also don't live in an area that gets much snow, some years we don't have any and I get monthly car washes.

Mechanic was checking the car and noticed subframe is rusted through underneath the plastic cladding. Audi dealers should cover this under warranty as it’s a safety issue. This happened due to poor designing.

SIDE MIRRORS TOTALLY BLOCK VISION AT CERTAIN ANGLES. I WAS STOPPED AT A TRAFFIC LIGHT ON A DOWNTOWN STREET. LIGHT CHANGED AND I MADE A LEFT TURN AND CRASHED RIGHT INTO A CAR THAT WAS TOTALLY BLOCKED FROM VIEW BY THE SIDE VIEW MIRROR. IT SEEMS I WAS ON THE WRONG SIDE OF THE LANE LINE, WHICH I COULDN'T SEE EITHER UNTIL I WAS ABLE TO CRAWL OUT OF MY CAR ON THE DRIVERS SIDE. THIS BEING UNABLE TO SEE LANE LINES AND ON COMING CARS HAS BEEN A CONTINUAL PROBLEM FOR ME, PARTICULARLY WHEN TURNING LEFT. THE DAMAGE TO MY VEHICLE WAS OVER $10,000. I AM CERTAIN I WAS GOING UNDER 10 MILES AN HOUR BECAUSE I WAS ONLY GOING TO TRAVEL ONE BLOCK FROM WHERE I WAS TURNING. THE CAR I HIT WAS DRIVABLE. MY CAR HAD TO BE TOWED.
