2020 Audi Q3

Last week 4/28/26, I purchased four Crossclimate 2 235/50R19 tires from Costco in [XXX] . Order #XXX. My question is two of the tires do not have a DOT number on the side wall. Two tires have DOT [1426] Along with [047X]. The other tires only have [047X]. No week or year of manufacture. Those tires appear to have a white powdery coating on the sidewall. I asked the technician at Costco about the missing DOT date on two of the tires. He didn't seem to know what I was taking about. Is it legal to sell tires without the DOT manufacturer date? Are theses tires safe to drive? Thanks for taking time to answer this question. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I purchased this vehicle new in June 2020. Since January 2022, it has experienced recurring water intrusion into the passenger cabin during heavy rain. Water leaks from the ceiling around the overhead console near the front reading/map lights. During heavy rain, water pools and causes the interior lights to turn on unexpectedly while driving. Generally, the lights cannot be turned off or immediately reactivate, creating a safety hazard at night. Water also drips onto the infotainment screen and center stack controls. To try to protect interior electronics, I have used absorbent materials to cover the center stack while parked and to wipe water while driving, which is distracting and unsafe. The issue has occurred repeatedly over multiple years and is reproducible. The vehicle has been inspected multiple times by authorized Audi service centers. Repairs have included cleaning sunroof drain tubes, replacing sunroof seals and adhesive pads, installing updated components, and water leak testing. Technicians confirmed water in the sunroof stowage tray and drains, and light malfunctions were attributed to water entering the cabin from the sunroof. Despite these repairs, the water intrusion continues to recur annually. During the most recent inspection, standing water was found in the rear sunroof drains, and sunroof removal and reinstallation was recommended but not covered. Service personnel confirmed the vehicle was properly maintained and not misused. The vehicle has approximately 17,000 miles. Primary symptoms are water dripping from the headliner and unintended activation of interior lighting while driving. Affected components include the sunroof assembly, drains, overhead console, and interior electrical systems. Other owners have reported similar issues, and multiple NHTSA Technical Service Bulletins acknowledge water entry from sunroof drains and seals. When I contacted Audi of America, I was informed that multiple complaints had been received, even that week.

I purchased my 2020 Audi Q3 in August of 2020. I am submitting this complaint regarding the recurring and unacceptable issue with my Audi. In February of 2023 my vehicle started shaking and stalled while driving. I could not restart for awhile, after a few minutes it restarted. I took it to Audi and they verified that the output of fuel pump did not meet minimum flow. They replaced the pump. Then in November of 2025 my car stalled again, doing the same thing, after a few minutes it would restart but kept intermittently stalling. This Fuel Pump malfunctioned again, and now this time both of them were not working properly. Both the High Pressure and Low Pressure Fuel pump was replaced again in January 2026. Having to replace a major component like the fuel pump twice on a 2020 luxury vehicle is unreasonable and deeply concerning. A fuel pump failure is not a minor inconvenience, it affects the reliability, safety and drivability of the vehicle.

I purchased a 2020 Audi Q3 S-Line (VIN: [XXX] ) on [XXX], with 27,564 miles on it. I bought the vehicle from a dealership that specializes in high-end aftermarket cars, and they provided a maintenance report stating the vehicle had passed all inspections at the time of sale. The vehicle had been imported from Canada to the U.S., and the Carfax report reflected consistent maintenance at authorized Audi dealerships in Canada, including a full inspection and alternator/electrical system check roughly a year before my purchase — with no problems reported. In early July 2025, I began experiencing issues with the MMI system: •A loud, persistent humming sound when using Bluetooth or the radio •Audio glitches and failed system reboots •No dashboard warnings or battery alerts After researching, I suspected a low-voltage or charging issue. I took the car to an auto parts store for diagnostics, and at 28,932 miles, they found the battery was severely depleted and the alternator had failed completely — it was no longer charging the system. This means the alternator failed only 1,368 miles after purchase, which is highly abnormal for a well-maintained, low-mileage luxury vehicle. Alternators typically last 80,000 to 150,000 miles. Audi has acknowledged similar issues in Q5 and A4 models, but nothing yet on the Q3. While I know the vehicle is out of warranty and was not purchased from an Audi dealership, I am requesting: 1.That this issue be formally documented and investigated for possible recall or defect pattern. 2.That Audi consider a goodwill repair, based on mileage, maintenance history, and how soon the failure occurred after passing inspection. 3.That this be flagged specifically for Q3s imported from Canada, as mine was. This failure could have left me stranded with no warning. I’m reporting it not only for my own case, but to potentially help others who may be silently experiencing the same issue.

The sunroof in the Audi Q3 leaks and the water drops from the ceiling INTO the cabin. Water also comes through the passenger side panel and drips onto the floor causing flooding of the floorboards. This is a KNOWN issue and Audi has released a TSB (technical service bulletin) to attempt to fix these, but it’s just a band aid. It keeps coming back over and over. Water intrudes into the center lights and they flicker and short out. Water drips from these lights into the center gearshift area and it is an extreme safety hazard. PLEASE force Audi to fix this and make it right with their customers. THIS IS A SAFETY ISSUE AND SHOULD BE A FULL RECALL

We purchased a 2020 Audi Q3 (36000 miles) from Carvana on December 5, 2024, and it was reported as having no past accidents. It was stolen on January 7. It was recovered on January 20 after the thieves crashed it into a telephone pole. The car sustained significant damage and there is evidence of blood on the interior. We have no idea the extent of any injuries because the thieves fled the scene. Our concern is that when we inspected the vehicle, we noticed that the airbags did not deploy.

What component or system failed or malfunctioned, and is it available for inspection upon request? Design and/or manufacturing flaw in Audi m/n 8R0071128C Fork Mount Bike Rack presents a risk of bicycle becoming detached from the rack/vehicle at highway speeds. I have retained all parts and they could be made available for inspection. How was your safety or the safety of others put at risk? Risk is bicycle flying off the roof of a car at highway speeds causing significant damage to the carrying vehicle and/or triggering a serious accident involving nearby vehicles. Has the problem been reproduced or confirmed by a dealer or independent service center? Not yet, but I have been engaged in a very slow moving dialog with a number of Audi representatives, most recently with Lori W, Region Case Manager, Audi CXC (Audi of America Customer Experience Center). Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Not Applicable Travelling at highway speed was a bang on car roof. Pulled over and found that the bicycle mounted on the Audi m/n 8R0071128C Fork Mount Bike Rack was no longer secured. After removing the bicycle, I saw that 1of2 threaded parts that clamp the bicycle fork to the rack was gone, bang heard likely was that part hitting roof. Remaining 2of2 threaded part was loose, could be turned by hand and was in danger of also falling off. It appears that the design of Audi m/n 8R0071128C enables these critical parts to unthread and detach during use. Possible fixes may be as simple as use of a permanent type thread locking compound during manufacturing or as complex as a redesign which does not present the possibility of failing in such an unsafe manner.
