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.

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.

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.

Component: 2016 Audi Q5 Available for inspection : UNKNOWN Safety risk: YES The car was just driven and parked in the garage, approximately 30 minutes prior to our discovery of the fire. My wife and I had to escape the fire. UNKNOWN YES The Town of Sterling, MA fire department investigated the fire and determined that the vehicle caused the fire (See attached report). Then, AMICA Insurance Company had [XXX] from NEFCO do an investigation. He verbally told us that he thought it was the car that started the fire, but he was told by the insurance company attorney to not make a written report (See attached email). AMICA had the vehicle brought to SD Lyons Facility in Seekonk, MA to investigate the vehicle's charred remains. Audi's representatives were also present. No physical evidence was found to prove that the car caused the fire. [XXX], Fire Investigator, in his attached email to us indicated that this does not mean the fire did not originate at the vehicle but that they could not find any physical evidence from the burnt remains of the car. In addition, there are eye witnesses, since the garage door was open. Our neighbors across the street saw what seemed to be small flames flickering near the right rear side of the car, which would flare up and decrease. Soon there after the car was consumed in fire. The description given sounds like a possible rule leak. This vehicle was purchased at Audi Nashua in NH and was regularly serviced by this dealership.

I PURCHASED A NEW EPA COMPLIANT AUDI Q5 DIESEL ON MARCH 28TH 2018. THE VEHICLE HAD THE EPA EMISSIONS REPAIR COMPLETED. SHORTLY AFTER PURCHASING THE VEHICLE I EXPERIENCED AN INTERMITTENT THROTTLE CONTROL ISSUE. IT PRIMARILY OCCURS AT SLOW SPEEDS. WHEN DRIVING SLOWLY, IF I SUDDENLY ACCELERATE, SUCH AS PASSING AROUND A VEHICLE IN FRONT OF ME, THE THROTTLE WILL NOT WORK, DESPITE MY PRESSING ON THE GAS PEDAL. I HAVE TO REMOVE MY FOOT FROM THE GAS PEDAL AND REAPPLY IT TO GET THROTTLE RESPONSE. I BELIEVE THIS IS AN UNSAFE SITUATION AND SHOULD BE ADDRESSED BY AUDI. I'VE HAD THE VEHICLE TO THE DEALERSHIP THAT SOLD ME THE VEHICLE TWICE AND THEY COULD NOT IDENTIFY THE PROBLEM. THE ISSUE HAS OCCURRED AT LEAST 12 TIMES. I WAS RECENTLY ABLE TO REPLICATE IT TWICE IN A CONTROLLED SETTING, HOWEVER, I WAS UNABLE TO REPLICATE IT AT THE DEALERSHIP. THE DEALERSHIP FOUND NO ASSOCIATED CODES WITH A SCAN.
