SERVICE BRAKES07/19/2026
Went to Mavis on Weber Rd in Bolingbrook, IL for front brake replacement on June 6, 2026. It took 6.5 hours when I was originally told when I called to schedule the appointment it would only take 1.5 hours, so it was obvious that something was wrong. Within 100 yards of leaving their parking lot after the service appointment, an obvious clattering was present. I immediately called them to let them know the replacement had not been performed correctly. Booked appointment with Audi of Naperville first thing Monday morning to have them fix whatever was wrong - the earliest appointment I could get was June 11. Drove the car until Wednesday evening when something went very wrong and constant clatter was replaced by loud scraping and brake lockup when I exited 355 on my way home from work. Called someone that night to have it towed to Audi for the next day's service appointment. Audi videoed their inspection and shared the video. Their inspection revealed one caliper entirely missing from the driver side brakes and the other caliper on that brake very loose. I paid Audi personally for that repair. I called Mavis customer service to notify them of my findings. After pulling the shop video from my brake appointment that day, they got back to me and said they would refund me for that appointment, the tow to Audi, and the Audi repairs. I have since been in touch with them and they said they mailed me a check on July 2. Since it has been 17 days since that date and it doesn't take mail that long to get to most of North America, I tend not to believe them. I have since learned that this Mavis brake replacement was negligent and could have resulted in an accident, with the potential of injury. I am contacting you because I don't want Mavis to take their responsibilities for the safety of their customers so casually.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER05/12/2026
2019 Audi q5 drive system malfunction/start stop malfunction. Error code will come on randomly in traffic and when you try to put your foot on the gas it hesitates and you need to push harder on the gas. Car will also lose acceleration power and take longer to reach desired speed. Drive system malfunction light will come on as well as an error stating start/stop system malfunction. Have had multiple sensors and battery replaced with only temporary results. Start stop malfunction will come on randomly at any time and then go away for a certain amount of time and come back again. This malfunction is constantly going on and off and is sometimes dangerous because you don’t know when it will happen, if it does happen you don’t know if you need to press harder on the gas, or if you do accelerate you don’t know if you’re damaging your engine. After multiple fixes at Audi dealership and other repair shops, them attempting to address this issue has done nothing for the car leaving me to believe this could be a fault. This issue has been going on for at least 10 months with multiple dealer visits attempting to address this issue.
SEAT BELTS,UNKNOWN OR OTHER04/22/2026
My seat belt warning has been going off intermittently. I received an extended warranty from Audi Subject: Seat Occupancy Detection System Limited Warranty Extension extending the warranty for my car. However, when I took it to the dealer they could not replicate the sound. I provided them a video of it happening. They said it was not showing as a fault on the computer and therefore refused to repair the seat under the warranty extension. This is a safety issue and it's recognized as one by Audi. This sensor is obviously malfunctioning for a lot of people or they would not have extended the warranty. Regardless of being able to "replicate" the issue, they should replace the sensor since it's a known issue and they extended the warranty on it.

A failed (frozen) Turbocharger Wastegate Actuator. An engine warning light came on and engine had less power. It had to be replaced. There was a settled law suit for the same issue covering this item in previous vehicles settled in 2025.

My 2019 Audi Q5 has 23,300 city-driven odometer miles. The vehicle has been serviced and maintained per the Audi Service Manual, based on months in service, not accumulated mileage. The vehicle has been garaged both at home and at work. The vehicle has never been driven off-road. When driving, an “All-wheel Drive: malfunction! You may continue driving. Please contact Service” warning message sounded and appeared on the instrument panel. The malfunction was diagnosed by Audi Honolulu and another Audi repair shop as a Shift Fork Unit issue and/or Quattro differential failure, which needs to be replaced. Audi has has a Technical Service Bulletin for a similar problem for the Q5. Audi Honolulu and Audi America refuses to provide a goodwill repair citing the age of the Q5. While the vehicle is 7 years old, a Shift Fork or Quattro Differential should not fail at 23,300 miles, regardless of age. I have been told by both repair facilities that the Shift Fork Unit or Quattro Differential could suddenly fully fail and seize causing a sudden loss of forward movement. I am afraid that if this happens at freeway speeds coming to a sudden stop could cause serious injury and if a vehicle behind mine slammed into me at freeway speeds a catastrophic or deadly accident could occur, especially at night or in inclement weather conditions.

The contact owns a 2019 Audi Q5. The contact stated that while driving approximately 30 MPH, the vehicle stopped and jerked, and the RED master warning light illuminated, and the message “Electrical Control Module” failure was displayed. On other occasions, while driving at undisclosed speeds, the turn signals and brake lights failed to operate as intended, and the message "Faulty Brake Light" was displayed. The vehicle was towed to the residence. The vehicle was taken to a dealer, where it was diagnosed, and determined that there was water trapped in the clogged sunroof drain, and the water leaked, and the control module was covered in water. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 95,000.
SERVICE BRAKES,FORWARD COLLISION AVOIDANCE03/23/2026
am writing to report a very concerning safety issue with my 2019 Audi Q5 and to request guidance on whether this may be covered under warranty or if my vehicle is experiencing a malfunction. On Saturday, while driving to an appointment, there was a bicyclist in the bike lane. Suddenly, the “Audi Presence” warning flashed red on my dashboard and the vehicle braked very hard on its own. I was not close to hitting the bicyclist and there was no imminent collision risk. The sudden braking was extremely frightening and could have caused an accident if a car had been behind me. It took quite a while for me to calm down and get my breathing back to normal after the incident. Then this morning, I received a dashboard warning that said: “Drive system: malfunction! Please contact service.” I am very concerned that this may be a malfunction of the automatic emergency braking or driver assistance system, especially after the unexpected hard braking incident. This feels like a serious safety issue. I am very concerned and very unhappy, as this situation felt dangerous and could have resulted in an accident.
POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM02/22/2026
Component: ENGINE AND ENGINE COOLING Summary: The turbocharger on my 2019 Audi Q5 failed prematurely. The initial check engine light and loss of performance began at approximately 48,000 miles, which is within Audi’s 4-year/50,000-mile powertrain warranty. The condition progressively worsened and the vehicle became difficult to drive safely in traffic due to reduced power and hesitation during acceleration. The turbocharger ultimately required complete replacement at 50,334 miles at a cost of $ 2511.20 This appears to be a premature failure of a major engine component. A sudden loss of power while merging or crossing intersections creates a safety concern. The vehicle has been properly maintained, is completely stock, and has never been modified. No warning was provided prior to the check engine light and rapid performance degradation. I am submitting this complaint because similar turbocharger wastegate failures have been documented in other Volkswagen/Audi vehicles using related engines, and a failure at this mileage should not occur in a properly maintained vehicle. Safety Risk: Reduced engine power and hesitation during acceleration creates a hazardous condition when merging into traffic or crossing intersections. Repair: Turbocharger replacement Repair cost: $ 2511.20 Mileage at repair: 50,334
SUSPENSION01/01/2026
The motor mounts and control arms are defective. The defective motor mounts that secure the engine causes the engine to shake resulting in collapse while driving. Both front control arms over the wheels are defective make clicking noises when turning resulting in the collapse of the car while driving. These problems were discovered by the dealer during a routine maintenance inspection. The warning lights did appear to have the vehicle inspected,
ENGINE,FUEL/PROPULSION SYSTEM11/03/2025
The problem was a turbocharger in my 2019 Audi Q5. The repair was done in January of 2023 by Audi North Houston / Sewell (17815 North Freeway, Houston, TX 77090, ph. # 281-586-1000). The cost was approximately $3,556. The replacement of the turbocharger was the same repair in the turbocharger class settlement (Kimball vs Volkswagen Group of America Inc., Case #XXX), but my vehicle is not apart of the settlement class vehicles. I verified the settlement class vehicles on the turboclasssettlement.com website, and I called their 855-779-6685 number to double check the settlement class vehicles. Their rep, Leisha, indicated, "The 2019 Audi Q5 is not a settlement class vehicle." The Audi Q5 vehicles identified in the settlement are for 2011 - 2014 model years. I had the same problem in my 2019 Audi Q5. Please help!
ELECTRICAL SYSTEM,AIR BAGS08/25/2025
Subject: Passenger Occupant Detection System (PODS) – Airbag Safety Concern Description of the Problem: The Passenger Occupant Detection System (PODS) in my 2019 Audi Q5 is malfunctioning. The system intermittently fails to recognize when a passenger is present, or it falsely indicates that a passenger is present when the seat is empty. This creates uncertainty about whether the passenger airbag will deploy correctly in the event of a collision. The issue has occurred multiple times. Safety Concern: Because the PODS system directly controls passenger airbag deployment, a malfunction could result in the airbag being disabled when an adult passenger is seated, or unintentionally activated when no one is present. This poses a significant safety risk. Request: I am reporting this issue as it appears to be a defect in the occupant detection system. Other Audi models from nearby years have had recalls related to PODS malfunctions. I urge NHTSA to investigate whether this defect extends to the 2019 Audi Q5 and to consider issuing a recall if warranted.
