Audi Q5 2024

21 Dec 2025 11,743 miles Audi Pre-sense slammed on the brakes while waiting to make a left. Pointing downhill slightly. No cars in the way. Turned it off completely. Was on the the Late setting. Will not stay off.

Vehicle had 2000 miles on it when warning messages of Distance warning unavailable and Audi pre sense limited with beeping signal sounding every few miles. The dealership confirmed the issue but only blamed a dirty sensor for the issue.The problem persisted even with cleaned sensor for another 6 thousand miles of driving after which I got an active lane malfunction warning. Since then all the warning messages and beeping stopped, but also the pre sense, and lane monitoring no longer work. Paid extra money for these extra safety features but they are not working.

The vehicle experiences sudden, uncommanded braking on clear roads due to a malfunction in the Audi Pre Sense system. The system falsely detects obstacles and applies the brakes abruptly, creating a safety hazard for occupants and surrounding traffic. The issue was reported to Audi Beverly Hills multiple times beginning July 2023, including through the dealer's online service request system. However, the dealer repeatedly failed to document braking concern on repair orders until insistent during latest visit. In one visit (August 7, 2023), the dealer reduced the Pre Sense sensitivity without creating a repair order or performing diagnostics. At other times, service advisors stated the vehicle was 'operating normally' or refused to record the concern unless it could be duplicated during a short test drive. On August 25, 2025, the dealer finally documented my complaint as 'car would brake randomly' and performed an SVM reconfiguration, but the issue persists. The vehicle is currently used rarely for safety.

The vehicle experiences sudden, uncommanded braking on clear roads due to a malfunction in the Audi Pre Sense system.

The issue was reported to Audi Beverly Hills multiple times beginning July 2025, including through the dealer’s online service request system. However, the dealer repeatedly failed to document the braking concern on repair orders until I insisted during later visits. In one visit (August 7, 2025), the dealer reduced the Pre Sense sensitivity without creating a repair order or performing diagnostics.

The vehicle is currently used rarely for saftey.

I am writing regarding a serious issue with my 2024 Audi Q5, which I purchased brand new and have owned for only 12 months. The vehicle has developed premature rotor wear, which is entirely unexpected given its age, my normal driving habits, and Audi’s reputation for quality. Brake rotors should not require replacement this early unless there is a manufacturing or material defect. This vehicle is still under warranty, and I am requesting that Audi inspect the braking system immediately and cover the cost of any necessary repairs under warranty. Please document the inspection findings and let me know if there is a known issue or Technical Service Bulletin related to this. I am not willing to pay for a component failure that is clearly not due to driver misuse or wear and tear. I expect a prompt resolution and would appreciate a written response confirming next steps. Possible Causes (Not Your Fault) Defective Rotors or Materials – If the metal quality was subpar or warped at the factory, they could wear prematurely. Improper Factory Installation or Torque – Incorrect installation can cause uneven wear or damage. Caliper or Pad Malfunction – Sticking calipers or bad pads can ruin rotors prematurely. Electronic Brake Malfunction – Audi’s advanced braking systems (ABS, brake hold, etc.) can malfunction and overuse the brakes.

Incident date: 06/30/25, Lift gate has closed while still trying to retrieve items from the cargo area, it seems if key is on the person and somehow the kick sensor was activated by accident the lift gate will shut down, the vehicle did make a beeping sound yet I was not clear where/what until the lift gate is coming down on me so I had to quickly move, the lift gate was quite close yet no sensor was activated to prevent the lift gate from shutting. This incident occurred prior to this date and I had to manually push the lift gate up since it was even closer to my body. I did some troubleshooting and read that the key should not be on the person, if so then someone can set off the kick sensor, designed for hands-free operation, can be sensitive and might accidentally trigger the liftgate to close if someone is too close to the rear bumper. Some users report this happening even without intentionally activating the feature. This is a safety issue that a vehicle does not have the sensor to detect an object or body to lift back up. A situation where a 2024 Audi Q5 liftgate closes by itself, potentially causing injury, is concerning. It does appear several factors can contribute to such a malfunction, causing a safety hazard. **Please note I have a video from my from home camera yet unable to upload it. I tried my best to take pictures from the video.

In addition to our complaint #11608543, filed on 8/14/2024, we are submitting a new and different safety concern today. While driving our new 2024 Audi Q5 with the adaptive cruise control set at the speed zone limit (55 mph), the cruise control adjusted itself down to 20 mph. The adjustment from 55 to 20 is sudden and extremely abrupt with some braking being applied. NO advanced warnings or discernible causes for the speed reductions were observed. If another driver had been following us, we likely would have experienced a rear end collision. We have experienced this malfunction on [XXX], east of Carroll, IA, and 1 to 1-1/2 miles north of [XXX], traveling in both the north direction and south direction. We have visited with the dealer numerous times. The dealership has hooked the vehicle to a diagnostic device and has reported to us that "the vehicle is performing as intended". We have submitted a claim with national Audi customer service representatives and they ruled that "if the dealer says that it is performing as intended", they have to deny our claim. Initially they offered "a gift" in compensation to us. We vigorously refused and stated that our goal was to have the vehicle fixed so it works properly or to have it retired from service before someone gets injured. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle exhibits multiple, unresolved safety-critical defects across software and mechanical systems that create an unpredictable and dangerous driving environment. Despite multiple repair attempts, the manufacturer has failed to certify the vehicle as safe for operation. 1. Critical ADAS Failures (Forward Collision/Lane Keeping): Automatic Emergency Braking (Pre-Sense): The vehicle suffers from unprompted alerts and phantom braking incidents, creating an immediate risk of rear-end collisions. Lane Keeping Assistance: The system has experienced unexpected steering pull, which could lead to an unprompted lane departure. Adaptive Cruise Control (ACC): The system consistently fails to detect lead vehicles in 40% to 50% of instances. The most recent failure was documented via timestamped screenshot on May 12, 2026, around 4:07 PM PT. This defect is reproducible and renders the automated safety suite unreliable. 2. Powertrain & Mechanical Defects: Pneumatic Air Leaks: The vehicle exhibits 100% pneumatic air leaks during acceleration. The service center has dismissively characterized a total pneumatic system failure as "normal," which I find technically unacceptable and a sign of neglected mechanical integrity. 3. Electrical & Starting System: Recurring Ignition Failures: The vehicle has experienced multiple failures to start, most recently leaving my child and me stranded for 10 minutes. Safety & Use Impairment: These intermittent failures compromise the vehicle's utility and the safety of my family. Incident History: The first time this occurred, I called Audi Roadside Assistance, but the engine started approximately 30 minutes later; as a result, I do not call roadside assistance now when it happens and instead attempt to restart it repeatedly. Current Status: I am forced to drive the car in a constant dilemma, knowing it might fail at any time and leave me stranded.

The component that failed was the tire/wheel system on a rental vehicle from Enterprise. While driving on a dry highway in New Mexico, a tire pressure warning light appeared. Because we were in a remote area, we stopped at the nearest gas station and added air to the tire. After adding air, the warning light temporarily turned off, so I believed the issue was low tire pressure. However, while continuing to drive, the warning light came back on. We were traveling through an isolated area where towns and service stations were very far apart, and I was attempting to safely make it to the next available gas station or service area. While driving at highway speed, I suddenly heard a loud “boom boom boom” noise. Immediately afterward, I saw the tire detach from the vehicle and roll in front of me before going off to the side of the roadway. I quickly attempted to safely pull the vehicle over. The sudden tire separation created a serious safety hazard for myself, my passengers, and other drivers on the highway. There was a risk of losing control of the vehicle, rollover, collision, or secondary accidents caused by debris or the detached tire. Other vehicles had to maneuver around us after the incident. The problem was not caused by weather conditions, debris impact, or unsafe driving. The failure happened during normal highway driving in dry conditions. The tire itself was not recovered after the incident. An Enterprise representative later asked where the tire was, but due to the sudden nature of the event and the remote location, we were unable to retrieve it. To my knowledge, the vehicle has not yet been formally inspected by the manufacturer or an independent repair facility. However, the vehicle should be inspected for possible tire defects, maintenance failures, wheel assembly problems, or improper installation. The incident was reported to Enterprise, and I contacted customer service multiple times regarding the safety issue and resulting damages and expenses.

Component/System Malfunction: The Audi Pre-Sense system has malfunctioned on multiple occasions. The system is available for inspection upon request. What Happened: On two separate occasions, the Pre-Sense system erroneously activated while making an unprotected left turn at a signal-controlled intersection. In both instances, the left turn signal was activated. After waiting for an oncoming vehicle to pass, I began the left turn. Despite the vehicle having passed, the Pre-Sense system activated, incorrectly perceiving the passing car as a threat. The system abruptly engaged emergency braking, locking the car in place and stalling it in the middle of the intersection. This left my two minor children and me stranded in oncoming traffic, creating an immediate and severe safety hazard. On a separate occasion, while driving straight in a lane with no intention of turning, the Pre-Sense system activated again. This time, the vehicle next to me slowed to make a left turn in its lane, which triggered my car's system to abruptly stop and stall in traffic. Risk to Safety: These malfunctions placed my family and other road users in immediate danger of a collision. In the left-turn incidents, the car stalled in the middle of an intersection with oncoming traffic approaching. In the straight-driving incident, the sudden stop created a risk of being rear-ended in traffic. Attempts to Resolve: After the first two incidents, I brought the vehicle to the dealership for inspection. A full diagnostic test was conducted, and I was told the Pre-Sense system was functioning "properly" with no repairs needed. Dealership staff admitted they had experienced similar Pre-Sense malfunctions in their own vehicles but dismissed the issue. I was advised to ensure my left turn signal was activated, despite already confirming the signal was on during both incidents. Warning Lamps or Symptoms: There were no warning lamps, messages, or other symptoms of the problem before the failures occurred.

Purchased 2024 brand new Audi Q5 with Kumho tires - KL33 235\55R19 from manufacturer Dec 2023. Have the car serviced at the Audi dealership per service recommendation. Tires were inspected and deemed roadworthy Jan 2025. By [XXX] (15 months post new purchase of vehicle) rear tire shredded on highway due to a known detreading issue with the Kumho tires. Causing pulling of vehicle into the central lane on highway. No accident or fatalities. Had emergency replacement of the affected tire and evaluation of the other three tires. It is noted during inspection of the three tires were also worn down atypically for the mileage (19,600). The rear tire on the driver side was also noted to not pass inspection due to early defective wear. All tires replaced, no accountability from dealership. According to the manufacturer warranty these tires would have all been replaced if bought personally (within 5 years of purchase, or under 60,000) , due to the fact the tires came with the vehicle there is no recourse per Audi dealership. Upon further investigation of Kuhmo tires there appears to be a known component regarding detreading of the tires especially with highway road speeds that has caused fatal accidents. Unable to reach Kuhmo tires to discuss accountability regarding gap in warranty coverage and defective tires. Per Audi employee this is a known issue with Audi and the tire company where they would rather pay off damages than correct the problem due to profit loss. My safety and others on the road were put in peril due to placing unsafe tires with known detreading issues on new cars, without any place for recourse when the said defective tires fail. Lack of consideration from Kuhmo tire company and Audi has placed a large population of car owners at risk, as Audi unable to get Continental tires knowingly and willingly opted for cheaper tires with known issues. Looking for accountability from these corporations. Will continue to reach out to Kuhmo for recourse. INFORMATION RED
