Lease Begin Date: May 1, 2024 Mileage at time of first incident: 16800 Current Mileage: 17,500 Incident Description: This vehicle has exhibited unintended rearward movement on two separate occasions following a "Drive System Malfunction" warning, each occurring immediately after shifting into Drive on an incline. The first incident occurred on February 20, 2025. Immediately after shifting into Drive, the vehicle displayed a "Drive System Malfunction" message and rolled backward before I was able to stop it. My [XXX]  child was a passenger. The system reset after restarting the vehicle. The second incident occurred under nearly identical conditions on March 19, 2025, again resulting in unintended rearward movement following the same warning message. My child was again in the vehicle. Time-stamped photographs documenting both events are available. The vehicle was brought to an authorized Audi dealership for inspection. The dealership was unable to replicate the concern. Low-voltage fault codes were identified, including a remote key and secure control module message, but no fault codes directly tied to the drive system were found. No corrective action was taken. I subsequently contacted Audi of America's customer support line and was assigned a Regional Case Manager. Audi's position has been that escalation to Audi Technical Assistance or engineering cannot proceed without dealership replication of the fault. No proactive diagnostic steps have been offered or taken. The concern remains unresolved. This complaint is being filed to document two occurrences of unintended vehicle movement associated with a drivetrain-related warning, and to request that Audi of America be required to investigate and address the root cause.

AUDI Q3 2024 POWER TRAIN

The rear inner brake pads wore out much faster then the outer brake pads on the vehicle.  On July 16, 2025, the car was taken in for service at an Audi dealership (Hoffman Audi in East Hartford, CT) and the inner brake pads were reported to be at 4mm.  The car had 19,678 miles.  On 12/18/2025 the car was serviced with 25,361 miles and the rear inner brake pads were replaced because they were at 1mm.  Besides excessive and premature wear of inner brake pads, this is a safety issue since the brake pad sensors are typically on the outer pads. Disc brake pads should wear consistently between inner and outer pads. Many social media forums report similar problems with Audi Q3 model wearing rear inner pads faster then the outer pads. 3mm wear on pads after only 5 months is excessive and dangerous, especially since the sensors cannot report pads are worn because they are on the outer pads.

AUDI Q3 2024 SERVICE BRAKES

The vehicleâs Adaptive Cruise Control (ACC) system intermittently fails to detect vehicles directly ahead at lower speeds. When this occurs, the car maintains the set speed instead of slowing down, creating a potential collision risk. The issue has been present since the vehicle was new and has occurred repeatedly over a two-year period.  Specifically, while driving in moderate or heavy traffic using ACC or Adaptive Cruise Assist, the system occasionally does not recognize a slower or stopped vehicle ahead. The car continues to accelerate or maintain speed until I manually apply the brakes. Once I brake and re-engage the ACC, the system immediately detects the vehicle ahead and resumes normal following behavior.  This pattern strongly suggests a software or sensor logic fault rather than driver error. There are no visible warnings, messages, or malfunction indicators before or during the failure. The problem has been reproducible multiple times under similar conditions.  The local Audi dealership has been informed, but as of now no official fix, recall, or service bulletin has been issued for this behavior on the 2024 Audi Q3. To my knowledge, the manufacturer has not publicly acknowledged the problem.  This malfunction poses a significant safety hazard, as it can result in the vehicle failing to decelerate in time to avoid a rear-end collision if the driver does not intervene quickly.  Component or system involved: Adaptive Cruise Control / Adaptive Cruise Assist (Radar-based driver assist system).  Availability for inspection: The system remains installed and can be inspected upon request.

Parking brake failure, contact service error message repeatedly pops up on digital screen behind steering wheel

The dashboard screen which operates the radio, GPS and other programs will shut down and the screen will show:  NOTE: SYSTEM RELAODING PLEASE WAIT.  The radio will continue to play but you cannot operate it.  Additionally, sometimes the screen goes completely blank and radio stops playing, usually comes back on in a couple minutes.  I've had it to dealer three times but problem is still present.
