2021 AUDI Q5 Complaints

I am submitting this complaint regarding a serious brake-related safety issue involving my Audi vehicle after recent brake service performed by an authorized Audi Meadowland dealership in [XXX] . In December 2025, I brought my vehicle to an authorized Audi dealership for replacement of the brake pads. The repair was completed by the dealership, and I trusted that the vehicle was safe to drive afterward. However, only approximately six months later, and after driving only around 1,000 miles since the repair, the vehicle experienced a dangerous brake-related failure involving the brake pad assembly becoming loose/detached while the vehicle was in operation. This incident occurred while my entire family was inside the vehicle, creating a serious safety hazard and placing all occupants at risk. A brake system component should not fail after such a short period of time and limited mileage following dealership service. In addition to the safety concern itself, I am also extremely dissatisfied with the dealership’s handling of the matter. The dealership did not proactively contact me regarding the repair status, and multiple attempts to contact them by phone went unanswered. I believe this issue may involve improper installation, defective parts, insufficient inspection procedures, or other serious safety-related service failures. I respectfully request that NHTSA review and investigate this matter to determine whether similar incidents may affect other vehicles serviced under similar conditions. Thank you in advance for your review on this matter. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The warning lite for the low tire pressure comes on randomly and consistently. I've taken it in about 5 times and have been told the tire pressure is fine and it is just a built in defect. I am concerned because I can't check my tires constantly and especially when I am on the freeway. I fear for my safety, the safety of my passengers and the vehicles around me. It happens on the loaners they give me, so I know it is not just my vehicle. I've talked to corporate and they seem very unconcerned. Can you help at all?' I'm considering selling it because of this issue, but don't want some one else coming back on me about it if they get in an accident.

The contact owns a 2021 Audi Q5. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated, and the vehicle stalled. Additionally, the windows independently rolled up and down, and the engine seized. While attempting to start the vehicle, the vehicle failed to start. The contact stated that the failure had occurred three times within five days. The vehicle was towed to the dealer where it was purchased. The failure was diagnosed with a failed gateway control module. The contact was informed that the gateway control module needed to be replaced. The vehicle was being repaired. The contact was informed that the plastic protective bag that covered the gateway control module was filled with water. In addition, the dealer informed the contact that the NHTSA Campaign Number: 21V947000 (Electrical System, Structure); recall repair was performed prior to the contact purchasing the vehicle. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 37,200.

The safety situation happened when my wife's car got stuck while driving at about 25-30 MPH in the middle of the road.Next day At the nearest Audi service center they found that water has gotten into the rear of the trunk and damaged the electronic module which caused the car to stall.The first repair was estimate at 4600 $ .After the repair the car was inoperable.The next repair was estimated at another 4 700 $.After the second repair the car was inoperable again and the service department told me that the car needed to replace the entire transmission .Which they estimated at another 20 000 $. So the total damage is around 30 000$ .I contacted Audi USA about the whole situation when I received a negative message regarding the solution . I would like to point out that up until the moment mentioned we had no problems with the car .After my personal investigation of the problem ,I found that there was a safety recall # 21V-947 for same problem .It was not issued for my car which meets all the criteria.It looks like it was hidden by the manufacturer. Audi distances itself from the whole problem and refuses to cover the costs of the damage.Thank good this happened on the city road where the speed is low .If this happened on the highway at 60 MPH it would have had tragic consequences .Where it would never have been figured out what caused the accident. From a safety perspective ,I m reporting this dangerous and unfair treatment of customers by AUDI USA regarding the hidden recall and denial of resposability that occurred and I request an investigation .

Control module located under rear seat became slightly wet from spilled liquid, and failed. Engine and electrical failure as a result of control module failure. Audi refuses to cover damages as warranty period is over. Vehicle design is defective.

Following a rear collision repair at an authorized dealer collision center, multiple ADAS safety systems were not properly calibrated despite insurance payment and shop representations that repairs were complete. WHAT FAILED: Lane Change Assist, Peripheral Camera System, Side Assist, 360-Degree Camera, Front Camera, and Adaptive Cruise Control were either not calibrated or calibrated in timeframes physically incompatible with manufacturer specifications. SAFETY RISK: Driver relies on blind spot monitoring and lane change alerts that may be non-functional or inaccurate. Without proper calibration, these systems may fail to detect adjacent vehicles, provide false alerts, or create blind spots in camera coverage, increasing collision risk during lane changes and merging. DEALER CONFIRMATION: Yes. Shop manager provided diagnostic logs as proof of calibration. Analysis shows 360-degree camera calibration executed in 18 seconds versus 40-60 minute industry standard, and zero calibration events logged for Lane Change Assist and Peripheral Camera systems explicitly claimed as completed. INSURANCE INSPECTION: Insurance company explicitly DENIED Lane Change Assist and Peripheral Camera calibrations on estimate. Shop admitted in writing these items were declined and blamed insurance for non-payment. No OEM calibration logs produced despite multiple written requests. WARNING SYMPTOMS: Systems may appear normal on diagnostic scan with no active fault codes, but this does not prove calibration was performed to OEM tolerances. Physical calibration requires target board positioning, laser alignment, and environmental verification that cannot be completed in documented timeframes. PATTERN CONCERN: This may represent a systemic issue where insurers deny ADAS calibrations, shops skip calibrations due to non-payment, vehicles are released as complete, and consumers unknowingly operate vehicles with compromised safety systems. Vehicle and documentation available for inspection.

Vehicle: 2021 Audi Q5 I am submitting this complaint regarding a serious safety defect involving unintended emergency braking. On September 10, 2025 and again on January 8, 2026, my vehicle suddenly applied emergency braking while I was driving and there were no vehicles, pedestrians, or obstacles in front of me. The dashboard displayed “Auto Pre Sense” during both incidents. These unexpected braking events created a high risk of a rear-end collision and placed me and other drivers in immediate danger. This is not a driver error, but a malfunction of the safety system. Because this has occurred more than once, I am concerned that the Audi Pre Sense system in my vehicle may operate unpredictably and cause a serious accident. I respectfully request that this issue be investigated as a potential safety defect.

While driving my 2021 Audi Q5, the vehicle experienced a sudden transmission disengagement without warning. The vehicle behaved as if it had shifted into neutral while in motion. When this occurred, pressing the accelerator produced no response — the engine would not rev and the vehicle would not accelerate. This created a serious safety risk as it occurred during normal driving conditions and could have resulted in a collision. After stopping the vehicle and shifting into Park and then back into Drive, the transmission temporarily re-engaged. The issue reoccurred multiple times. Prior to one of the failures, the vehicle hesitated and bucked when starting from a stop. A warning message later appeared stating: “Transmission malfunction. You may continue to drive but will be unable to reverse.” The vehicle was taken to an authorized Audi dealership. Audi of America approved replacement of the transmission control module (mechatronic unit); however, this repair did not resolve the problem. After repeated failed adaptations and diagnostics, the dealer confirmed that the entire transmission requires replacement, citing internal gear set failure. The dealer documented that: Basic transmission settings and adaptations were attempted at least five times The failure consistently occurs at the same gear position A similar Audi Q5 case required full transmission replacement Audi Technical Assistance Center instructed the dealer to replace the transmission Despite this, Audi of America has refused further assistance due to the vehicle being slightly outside the standard warranty period, even though the mileage is extremely low and the failure is safety-related. This appears to be a defect involving the Audi S-tronic transmission, as similar complaints have been reported by other owners. The sudden loss of propulsion while driving presents a clear safety hazard. Safety Impact Sudden loss of acceleration while driving No throttle response during failure Occurred wit

Date of Incident: 11/09/2025 • Location: I-30 near Cumby, TX (towed to Audi Fort Worth). Daughter was stranded on busy highway in middle of nowhere. Texas State Police came to her aid and helped w tow truck which cost $650. Engine catastrophically failed at ~50k + miles due to metal shavings throughout oil — Audi Fort Worth made the statement and I have picture of metal shavings. Which is the exact defect in **NHTSA Recall 22V753 / Audi TSB 13i5** (connecting rod bearing damage from factory machining debris). **Symptoms match TSB 13i5 Pages 1, 10–11 (“NOT OK” filter examples)**: - March 2025 oil change at 50,032 miles: **no metal** or at August oil change. Neither Audi corporate or Fort Worth care. Claimed we bought used car and didn’t have oil changed at Audi dealer. This statement violates federal law: - **49 U.S.C. § 30120**: Safety recall remedy free of charge to all owners regardless of purchase history or service location. - **TSB 13i5 Page 1**: Covers **ALL 2021–2023 Q5s** (42,689 units) — **no VIN exclusions**. - **NHTSA 22V753**: Risk of engine failure, loss of motive power, potential fire** — undriveable vehicle

While driving one day, several warning messages appeared on the dashboard, but would then disappear. The next day, the car engine would not start and the vehicle dashboard would not turn on. The car was inoperable and had to be towed to a dealer service center. Dealer confirmed that the issue was caused by liquid entering the gateway control module. A safety fix had been applied before during a 90S9 recall in 2022, but it appears that fix is inadequate or defective.
