1. Failed/Malfunctioned Component: March 2025 - Air Conditioning (A/C) control valve, May 2025 - A/C line and seals. 2. Safety Risk: I heard an explosion underneath the vehicle shortly after parking the vehicle in a shopping center. Upon quick inspection, I did not initially observe any obvious broken parts, components, nor any warning lamps, messages or symptoms. The following day while charging the vehicle in my garage, I noticed a fluid leak emitting from under the vehicle. The fluid was identified as R1234YF refrigerant, which is flammable. The risk of that fluid igniting is even greater while the vehicle is charging. 3. The problem was reproduced by the dealer under both incidents (A/C control valve failure & A/C lines and seals explosion) and confirmed as a manufacturer defect. 4.

Our Audiu Q8 has had a host of safety issues since purchased in December 2023 and we have been denied or delayed on a buyback twice. The vehicle has been unable to be moved 3 times due to battery (12V and relay) issues that left my wife and [XXX] stranded at home. On one occasion the vehicle could not be moved by the tow service whatsoever. The charging system cable (known to cause fire hazard by Audi with open safety bulletins) created a fire in our 240 outlet box and also melted the plug and connected cable. The vehicle also continues to read road signs on exit ramps and hard brake check almost causing accidents while driving on the highway with cruise control. The feature for traffic sign recognition is tuned off but the vehicle continues to do this hard and sudden brake checking. Audi
From the first day I purchase the vehicle, even when the sales person was walking me through the vehicle, the vehicle window was constantly retracting itself lower when i tried to close it. When the window is half way open, and the driver is trying to close the window, the window automatically retracts and lowers the window. causing distraction for the driver and safety hazards from the road and environmental conditions.
I have two Q8 Etron, and this q8 is also having the same issue as my other q8. When the windows are open half way, and the driver is trying to close the window because the car is moving faster speed, the window automatically retracts and opens the window even lower. this is really distracting to the driver especially when there is a safety hazard on the road or the weather. please address this issue to improve safety of the vehicle
CHARGING SYSTEM DEFECT: The manufacturer-supplied portable charger (rated 9.6kW at 240V/40A) delivers only 7.4kW — a 23% shortfall. The authorized dealer confirmed this measurement in March 2026 but refused to repair, stating "no issues." The charging rate also degrades over time without manual reset. The vehicle also intermittently fails to charge at DC fast charging stations — it begins charging, then stops within minutes displaying "Malfunction of charging" error. Other EVs charge normally at the same stations. SAFETY RISK: Charging failures create a stranding hazard. The vehicle can fail to charge at public stations without warning, leaving the driver unable to complete trips. REPAIR HISTORY: 5+ visits to two authorized dealerships over 10 months (May 2025–March 2026), 16+ days out

Owner: Jyima Ofori-Atta Vehicle: 2024 Audi Q8 E-Tron (55) VIN: WA15AAGEXRB031696 Current Mileage: Approximately 6,335 miles Dealer: Audi Van Nuys, Sherman Oaks, CA Lease Start Date: February 1, 2025 Car charging issue I recently received my vehicle back from service following an extended stay related to recurring charging system and software issues. While the vehicle has been returned to me, my primary concern is the likelihood that the same charging failure will occur again, as it has multiple times in the past. Due to the history of unresolved charging failures and the absence of a clearly communicated permanent fix, I am extremely concerned about the vehicle’s reliability moving forward. Since taking delivery of the vehicle, I have experienced multiple charging system failures that re

Whenever the physical brakes are engaged during daily "brake cleaning" during the first mile of driving, or whenever the regenerative brakes do not engage, or when the physical brakes are engaged under heaving braking where the regenerative braking system's braking capacity is exceeded, the vehicle shudders as the brakes grip and slip. When inspected by Audi of Mendham, the service technician noted the rotors were "warped" and had "debris build-up". Despite the vehicle performing daily "brake cleaning", the build-up has remained. Despite normal use of the vehicle over the past 22,000 miles over two years, the rotor have warped causing inconsistent brake pressure to be applied. Under heavy braking where the regenerative system is exceeded, this could cause the vehicle to swerve due to uneve
While operating my 2024 Audi Q8 e-tron at 30 mph, I attempted to slow the vehicle to make a turn. Upon pressing the brake pedal, the regenerative braking system failed to engage properly, and the expected deceleration did not occur. The brake pedal felt very soft and the vehicle continued to move forward with nearly no braking force, despite significant pressure being applied to the pedal. The failure appears to be a total malfunction of the 'brake blending' system—the critical handover between the electric regenerative system and the hydraulic friction brakes. Even as a secondary safety measure, the hydraulic brakes failed to provide adequate stopping power. This resulted in a significantly extended deceleration distance that nearly caused a collision. No warning lights appeared on the
Brake rotors warped around 33k miles under standard operating conditions. Manufacturer refused to replace under warranty. On an EV, this is completely unacceptable mileage to replace brakes (should last 70-100k or more). Research shows others with this model encountering similar issues. There must be a defect with these rotors.
Two years of break issues where the breaks shudder badly on and off - whole breaking system was replaced and problem still occurs to the point my wife won't drive the car because of the shuddering - audi deny the problem even though they replaced all the braking system - its a well known design fault - Audi has to take responsibility!
I have experienced a persistent brake vibration issue since I first acquired my 2024 Audi Q8 e-tron in December 2023. The vehicle has required two full brake rotor and pad replacements within 12,000 miles, which is highly abnormal and suggests a fundamental defect in the braking system. Audi North Miami acknowledged the issue and replaced the rotors and pads under warranty in October 2024. However, just four months later (February 2025), the exact same issue reoccurred, and now Audi is refusing to cover the repairs, claiming it is normal wear and tear. Brakes are a critical safety component, and the fact that a luxury SUV requires two full brake replacements in such a short period raises serious concerns about engineering defects or improper installation. This defect increases stopping dis
Complaint Regarding Brake Safety Issue – 2024 Audi e-tron Q8 Launch Edition Under Warranty While driving my 2024 Audi e-tron Q8 Launch Edition, I encountered an accident ahead and had to brake hard. As I applied the brakes, the entire car began to shake violently, nearly causing me to lose control. Prior to this incident, I had already experienced pulsating braking at lower speeds, which made the vehicle feel unsafe. After the incident, I noticed that the car no longer brakes evenly, even at low speeds. I brought the vehicle to Rusnak Audi Service Department, where Service Advisor Jorge Canul initially stated that the issue was "normal" and attributed it to the front motor. When I expressed concerns about safety and requested further investigation, I was later informed that the issue was

Front passenger door doesn’t always open when using the inside door handle. When you pull the door handle the door partially unlatches not allowing the door to open. You must then release the door handle and then repull the handle for the door totally unlatch and open. I was told by the dealership that these electric door latch’s are poorly designed. Cars been in the dealership 6 times for this in the past 2 months and it’s still not fixed.
I was approaching an intersection with my left hand turn signal on and there were no cars oncoming and none behind me. As I went to turn the car slammed to a stop and I couldn't turn. I thought someone slammed into the back of me. The cars that were on the sides of the car at the traffic lights were alarmed as well. I had to back up and wait at the light. It was so dangerous, if the other cars weren't paying attention someone would have t-boned me and who knows what would have happened. My back and neck especially hurt for a few days. I immediately called the dealer and they said they never heard of that happening. I went through the car system and was able to turn off the pre sense, assuming that is what it is. It then happened AGAIN to my husband driving the car in the middle of an inter

Hello, I would like to bring the below serious safety concern to your attention which will likely require a recall to be performed: I brought my vehicle to an Audi dealership (Audi of North Austin, TX, USA) and physically demonstrated the issue, which is that the INTERIOR door handle (on all doors) will NOT unlatch unless the passenger pushes on the door while the door handle is pulled. This vehicle has an electronic door latching system and it will remain latched after the door handle is pulled open if the passenger does not also push on the door while pulling the handle. If the door is pushed a few seconds after the handle has been opened (and remains open) the door WILL NOT OPEN. Additionally, there is a safety direct cable connection to the latch that often does not work on the f
steering 1 complaint shown
On 3 separate occasions the vehicle has abruptly stopped while making a left turn endangering our lives. The pre-sense automatic braking malfunctions and stops the vehicle as we begin a left turn. The turn signal is engaged and the car incorrectly determines it needs to perform an emergency braking action. The only oncoming traffic is 200 yards or more away. In addition the lane keeping assistance on the vehicle in many cases also malfunctions abruptly steering the car into a left hand turn lane. We reported the issues to Audi service and they took no action other than informing us of some update coming in 2025.
