AIR BAGS
Vehicle: 2025 Audi Q4 e-tron Premium Plus quattro Safety concern: Side airbags failed to deploy during a significant driver's-side collision. On XXX, I was driving my 2025 Audi Q4 e-tron at approximately 45 mph in [XXX] when another vehicle, a Hyundai, struck the driver's side of my Audi near the front driver's door and front wheel area. Immediately before the collision, I noticed the other vehicle in my left peripheral vision and heard tires screeching. I do not know the Hyundai's actual speed. The impact caused extensive damage to the driver's side of my Audi, including the front and rear driver's-side doors, door seals, and surrounding structure. The front driver's door could not be fully closed afterward. My head struck the driver's-side window during the collision, and my glasses were dislodged. I was evaluated in an emergency department and diagnosed with a concussion. Despite the significant driver's-side impact, neither the driver's side curtain airbag nor the driver's seat-mounted side airbag deployed, to my knowledge. The airbags in the striking Hyundai reportedly deployed. My Audi continued traveling mostly straight after the collision until I brought it to a stop. I observed that the Hyundai had rotated after the collision. I am concerned that the Audi's side-impact restraint system may not have functioned as intended. I am requesting that NHTSA review this incident as a possible airbag nondeployment safety issue. Following the collision, the myAudi app displayed the front windows as open, although my husband confirmed that the windows were intact and fully raised. The app also indicated that doors were open; the driver's front door was physically damaged and could not latch completely. I am seeking preservation and independent retrieval of the crash data and airbag control module information before the vehicle is repaired, dismantled, or salvaged.

ELECTRICAL SYSTEM, ENGINE, UNKNOWN OR OTHER
Repeated A/C Failure in Extreme Heat Component: Air conditioning/cabin cooling Mileage: Approximately 49,350 miles as of XXX The vehicle repeatedly loses all A/C cooling in cabin in extreme heat (100°+F), with cooling returning in cooler weather. On XXX, traveling to [XXX], the A/C failed near [XXX]. After shutting off the vehicle for 20 minutes without success, we drove another 1.5 hours in 110–115°F heat with our two children. Audi Las Vegas serviced the refrigerant system August 10 at 47,069 miles, temporarily restoring cooling. On XXX, the A/C failed again in approximately 101°F heat during a trip to [XXX]. We drove approximately one hour of our trip home without cooling, with our children and [XXX] puppy, having to make unplanned stops along the way to attempt to stay cool. Audi Carlsbad could not reproduce the issue during its XXX inspection and recommended testing in hotter conditions. At Audi Rancho Mirage on XXX staff reportedly acknowledged frequent A/C issues with this model in hot climates. The dealership stated the system apparently prioritizes battery cooling over cabin cooling in high temperatures and offered no repair. The A/C failed again at pickup in 106°F heat and remained inoperative during our return trip. Safety Concern and Current Status Unpredictable loss of cabin cooling in extreme heat risks heat-related illness, particularly for children and other vulnerable occupants. The defect persists despite three dealership visits and refrigerant service. No warning lights, injuries, or crashes have been reported, and no permanent repair or definitive diagnosis has been provided. As of XXX the vehicle had approximately 49,350 miles, and we have limited its use to essential trips. We request that NHTSA investigate whether this recurring failure constitutes a safety defect.

FUEL/PROPULSION SYSTEM
I'm writing to report a serious safety issue with my 2023 Audi Q4. Today, Tuesday, October 6, 2026, at approximately 7:18 p.m. Eastern, my vehicle suddenly failed to accelerate from an intersection while I was driving, which nearly caused an accident. I was making a left turn from a T-intersection crossing a lane with opposing traffic, but my car accelerated very slowly causing the perpendicular to break (and honk). Fortunately, they were paying attention and slowed appropriately. Given the danger this poses, I want to formally report it so it can be investigated. This has not been confirmed by a dealer No warning lights were visible.

I tried to charge my Q4 at home, the charging connector to the car had warning red light. So, I checked up dashboard. It's said that AC charging is limited. Eventually, I can't charge. I went to the audi dealer. They said it's simple software issue. Waited 2 hours, one day works fine. Same issue. They don't know what to do. I am still wating from audi USA.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Re; Audi Q4 etron vin [XXX] On XXX while on my driveway, approaching the garage, a sound came from the dashboard, a written message appeared on the screen, and almost simultaneously the car suddenly accelerated, going thru the partially open garage door, hitting the left side of the car already parked on the right side of the garage, and hitting the central air conditioning unit in front of it, damaging both cars, the air conditioning unit, garage cabinets, sink, and shelving. We have asked Audi to look into the car’s computer/recorder to see what information they can extract without avail. We recognize that some cases of unexpected unintended acceleration may actually be driver error, and we thought that Audi would be more interested in investigating this issue than we would be. Audi's position was essentially that since our insurance company had paid us for the damaged cars nothing more needed to be done. We thought that before this car is taken apart, it would be important to find whether or not this was truly unintended acceleration.

VEHICLE SPEED CONTROL:ACCELERATOR PEDAL
The contact owns a 2025 Audi Q4 Sportback E-tron. The contact stated that while the vehicle was inside the car wash, the contact shifted the transmission from neutral(N) to drive(D), but the vehicle experienced unintended acceleration. The contact lost control of the vehicle and crashed into the car wash wall, damaging the front driver's side of the vehicle. Police arrived at the scene, but no police report was filed because the crash had occurred on private property. The vehicle was towed to a tow yard. The dealer was notified of the failure. The failure mileage was approximately 14,000.

ELECTRICAL SYSTEM
Within the first 6 months of owning the car my 2024 Audi Q4 E-tron premium door handle lock - unlock would not work and the car would intermittently not start. The dealership service replaced the 12-volt battery which has corrected the door handle lock-unlock issue; however, it has not corrected the no start problem. If I exit and enter the car multiple times it will eventually start (automatic seat start). The dealership service department cannot reproduce the problem therefore no solution has been made or offered. I have another appointment to leave the car 9/24/26 - due to additional starting concerns - on 9/11/26 my car would not start while at the dealership and a member of the service department witnessed the issue. On 9/17/26 - after multiple attempts to start the car and finally getting it into D - while initiating momentum and driving - the car shut down!! Luckily I was still in a parking lot and not on the highway!!

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
On Friday, XXX, I stopped my vehicle in a parking spot, exited, and returned to my vehicle. I put it in drive, moved from the parking spot, and before I could reach 10 mph, the vehicle began to shake/vibrate violently, and the dash lit up with electrical system malfunction warning. On Saturday, XXX, my [XXX] daughter, who was driving my [XXX] and [XXX] daughters home, called me to tell me that the vehicle failed and that she had "safely pulled into someone’s driveway". We had been out of town, and she was caring for her sisters and my vehicle has the carseats. My [XXX] daughters frequently drive my car. She was a mile away from home, so she did “the routine”. She had to do this 5 times - with me on the phone - just to get the vehicle home and her sisters to safety. After my husband and I returned home Saturday, XXX, we got in the vehicle so that we could possibly get it on video. We were able to finally get video evidence of the problem so that we can no longer be turned away from Audi with the excuse of “no evidence” of a problem. The history: XXX, I had my vehicle towed to Audi, because the electrical system malfunctioned in our driveway not in motion. I was told that the problem could not be replicated and, therefore, not resolved and that Audi “requests vehicle to be released to the customer”. On XXX, we contacted Audi once again to report two instances of the same problem, both which occurred while in motion. The vehicle then went limp and brought me to a stop on the side of the road, on a sharp bend, with, again, my two youngest children in the back seat. Then, my husband and I were in the vehicle and had stopped at a traffic light on a 55 mph road. XXX diagnosis: “Could not duplicate customer concern during several test drives, found no relevant fault codes” and “no obvious electrical or mechanical failures during hoist inspection at this time” were the notes in the report back to us.

UNKNOWN OR OTHER
The air conditioner warning light came on in April 2026. I took it to dealer to be checked. Dealer said no problem. That warning light went on intermittently through May, June and July. By end of July I took it back to dealer. The evaporator was indeed malfunctioning and emitting carbon dioxide into the cabin when the air conditioner was on. While repairing the evaporator system, the plastic cover over the ground stud broke and required replacement. The vehicle was out of service for 10 working days.

ELECTRICAL SYSTEM
The high-voltage charging system has repeatedly malfunctioned. The vehicle intermittently displays a "Charging System Malfunction" warning and a message that only AC charging is possible, the charge-port indicator blinks green and then red, and the vehicle cannot be reliably charged. The vehicle and the affected charging components are available for inspection on request. Safety risk: because the vehicle cannot be dependably charged, it can be left without sufficient power to complete a trip, creating a risk of losing motive power and leaving the driver stranded, potentially on a roadway or in an unsafe location. The affected onboard charger is the subject of Audi Safety Recall 93FR (Onboard Charger with Integrated DC/DC-Converter) — a component the manufacturer has already identified as safety-related. As of 8/10/26, the fault has returned and I no longer consider the vehicle safe to rely on for normal driving. Reproduced and confirmed by a dealer: yes, on multiple occasions. On 06/03/2026 (~52,771 miles), Audi Tysons Corner recorded the "Charging System Malfunction / unable to charge / blinks green then red" complaint and performed a combined software update (ID.S 5.4.3, TSB 2080398). On 07/08/2026 (~54,673 miles), the same dealer recorded the "Charging System Malfunction / only AC charging possible" complaint, reported diagnostic fault P33E800 (charge socket / charge connector lock mechanical malfunction), and replaced the Connector Lock 1 Actuator (F498). The defect has since returned. Inspected by the manufacturer and others: the vehicle has been inspected and serviced only by Audi authorized dealers (Audi Tysons Corner and Audi Chantilly), including warranty and recall work, with diagnostic/GFF logs uploaded to Audi. On 10/13/2025 (~37,447 miles) Audi performed Safety Recall 93FR on the onboard charger, and the high-voltage charger was subsequently replaced under that recall. The vehicle has not been inspected by police or insurance. Repair invoices are avail

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I am filing a safety complaint regarding my leased 2025 Audi Q4 e-tron, leased new with under 500 miles and now at approximately 8,200 miles. The vehicle is available for inspection upon request. The vehicle has ongoing brake-related issues affecting low-speed operation: a rough or grinding brake pedal feel and intermittent brake squeal during rolling stops, turns, and parking maneuvers. The most concerning issue is unexpected parking brake or emergency braking activation during low-speed pull-off and parking maneuvers, causing the vehicle to abruptly jolt to a stop. This has happened approximately four times between March and July 2026, beginning around 6,000 miles, including while pulling to the roadside and while parking with my foot already on the brake. No other vehicle was nearby during these events, and the behavior is not consistent or predictable, creating a risk of unexpected stopping during normal low-speed operation. This does not match normal EV regenerative braking based on my experience with other EVs, including another Q4 e-tron, and appears specific to this vehicle. I reported these concerns to authorized Audi dealers and Audi Customer Experience. In February 2026 I brought the vehicle to an authorized dealer for a brake-related appointment; a technician did not inspect it because the service associate said he did not think anything was wrong, and I later learned the appointment was canceled rather than documented. I also raised these concerns with a second authorized dealer during a one-year service visit and on two additional occasions. The problem has not been reproduced or confirmed by a dealer to my knowledge, and has not been inspected by police, insurance, or an independent service center. I am not aware of warning lamps before the jolting events. I am concerned the vehicle may have a defect involving the service brakes, parking brake, emergency braking system, software, sensors, or control-system behavior.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
I am reporting a severe safety recall compliance failure and fraudulent reporting by an authorized dealership regarding a 2023 Audi electric vehicle. On May 30, 2024, under Repair Order 227719, the dealership officially certified to the NHTSA and Audi that Safety Recall 93U6 (Compact/Portable Charging System Cable) was fully completed. The dealership never actually removed or replaced the hazardous, fire-prone charging hardware. The original recalled cable (Part Number: 8V4.971.675.BB) remains in my home and is available for inspection. The dealer falsely reported a federal safety remedy as remedied while leaving a fire-hazardous component in a consumer's possession. The vehicle suffers from chronic, sporadic overnight charging failures where the vehicle indicates it is charging via a green indicator light but fails to draw power overnight. The vehicle was returned to the same dealer in July 2026 for this defect, at which point the false historical recall reporting was discovered on the printed history report

SERVICE BRAKES
On three occasions, while in regenerative braking mode, my car failed to engage the brakes at low speeds. After pressing on the brake pedal for several seconds with no response, the wheels then locked completely - but only after the car had traveled had traveled around 30 feet. The dealer has inspected the car and has not been able to replicate the problem, so they say there is nothing they can do to correct it (although they are NOT saying that they don't believe me). There were no warning lights or messages about a failed system - the brakes just didn't work. This was very unnerving to me, and I don't see how I can drive the car without some corrective measures taken. I was fortunate that these incidents happened where no person or other car was nearby, but that was only luck. I reported the three incidents to the dealer, and brought the car in twice for them to inspect the car.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
While driving in the left lane on a particularly bumpy section of Interstate 5 South in Seattle (just before the NE 50th Street overpass), I had to quickly hit my brakes as traffic abruptly slowed. The Audie "Pre-sense" sytem did trigger, but emergency autonomous braking did not. My car did not slow down as I hit the brake, and I had to swerve onto the shoulder and put it in "B" mode to trigger full regenerative braking to stop the car. The weather was clear and the road was dry. I had previously had the vehicle in to the dealer as the brakes were making a load creaking sound, which they indicated was normal. The day after this most recent incident, the vehicle was towed (at the dealership's recommendation) in. It's been there for the past week and they are now claiming it is operating as expected.

POWER TRAIN
My Audi Q4 Etron has had this issue since it was new. The car has a sensor as part of the drivers seat. Once you sit in the seat the car turn on and you can start driving. The problem is if you make any movements, like turn to look back while your backing the car up or you reach over to pick up something off the passenger front seat the car will abruptly stop and turn off. It can take up to two minutes for the car to start again, twice i was left in the middle of a four lane intersection stranded. The second time it nearly caused an accident as multiple cares slammed their brakes. The dealership said that its a common complaint but there in nothing they can do, i was told to stay seated and to not move while driving. My wife also got stranded blocking an intersection and it also almost caused an accident, she was so scared that she will not drive the car or ride in it when im driving. Audi need to fix this before someone gets killed. I hope you can help.

SERVICE BRAKES, ELECTRICAL SYSTEM, STEERING
On March 20, 2026, while my 2022 Audi Q4 e-tron (VIN: [XXX] ) was parked in my private garage at approximately 98% battery charge, I attempted to start the vehicle and experienced a complete electrical system failure. All electronic systems failed simultaneously, including: brake system (Brake System Failure warning displayed), parking brake sensor, traffic/charging system, power windows, and side view mirrors. The vehicle could not be placed into neutral. AAA was dispatched and the vehicle required a jump-start to the 12-volt auxiliary system before it could be moved. The vehicle was towed to Audi Beverly Hills for inspection. The dealership diagnosed the fault as: Control Module Main Processor Performance, Symptom Code 20079, per Technical Service Bulletin TSB 2074484/3. Per that TSB, the dealer was instructed by Audi of America to create a PSS (Pending Service Solution) record, erase the fault memory, and release the vehicle to me with no repair performed. The stated guidance from Audi of America to the dealer was to inform me that this is "an extremely infrequent fault" that is "being reviewed." No fix exists. No timeline for a fix has been provided. The vehicle was released to me with the underlying defect unresolved. This is a known, manufacturer-acknowledged defect with no current remedy. As a fully electric vehicle, the Q4 e-tron's braking and all safety systems are electronically dependent. A recurrence of this fault while driving presents an unreasonable safety risk. I am requesting NHTSA investigate whether TSB XXX /3 and Symptom Code 20079 warrant a formal safety recall. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM, POWER TRAIN
I am filing this complaint due to ongoing electronic and drivetrain malfunctions that may impact safe vehicle operation. AWD System Malfunction (Primary Safety Concern) The vehicle repeatedly displays four-wheel drive system malfunction warnings. I have brought the vehicle to the dealership three times for this same issue. The malfunction continues unresolved, raising concerns about traction, stability, and drivetrain reliability. Intermittent Entry Failure Biometric entry intermittently fails, forcing use of the key fob. This could delay access in emergency situations. Remote System Failures Remote vehicle functions (lock/unlock and climate control) operate inconsistently or fail entirely, often generating error messages. Audi has stated this is a system infrastructure issue with no current fix. Battery Power Inconsistency Although the battery indicates 100% charge, actual available power never reaches full output and drops shortly after driving. This creates uncertainty about vehicle performance and usable range. HUD Feature Does Not Perform as Advertised The head-up display does not show surrounding vehicle speeds as advertised, only colored indicators. This removes expected situational awareness information. Summary The vehicle exhibits repeated drivetrain warnings, electronic access failures, and inconsistent battery performance. These issues persist despite multiple service visits. I am requesting this complaint be formally recorded and investigated due to potential safety implications.

SUSPENSION
Front suspension ball joint failure occurred while driving approximately 70 mph on an interstate highway, resulting in sudden loss of vehicle control and requiring immediate emergency response. The vehicle is a 2023 Audi e-tron A5. Two weeks prior to the sudden failure, an Audi dealership inspected the same front corner of the vehicle following earlier damage and stated that the front suspension and wheel components were safe and the vehicle was fit to drive, replaced the rear right tire and recommended replacing the rear wheel housing after not being able to get the full car alignment to spec. I told them I wanted to defer that service until later in February unless it was catastrophic when we discussed the findings. They told me that the car was safe to drive and proceeded with the wheel alignment and replacement on the rear. The ball joint failure was catastrophic and presents a serious safety concern, particularly given the recent dealer inspection and the short time between inspection and failure. Warranty coverage was later denied by the dealership, despite having just inspected the car for damage and claimed that the failure of the front ball joint was caused by deferring the rear wheel housing service. I am submitting this complaint due to the safety implications of a suspension component failure at highway speed and concern that the defect may have existed and should have been detected during the prior inspection.
