What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2023 Audi A4, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.

The contact owns a 2023 Audi A4. The contact stated that while driving at an undisclosed speed, the vehicle independently accelerated. No warning lights were illuminated. The brake pedal was depressed; however, the vehicle failed to stop as needed. The vehicle crossed a busy street and drove down an incline. The vehicle jumped a curb and came to a stop at a nearby hotel parking lot. There was no injury sustained. A Police report was not filed. The vehicle was driven to the residence. The vehicle was later towed to the dealer, where a diagnostic test was performed. The dealer found no failure with the vehicle. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 30,000.
While driving southbound on [XXX] near [XXX] in Mississippi, the advanced driver-assistance systems (lane assist and radar) did not operate as designed. At highway speed, the vehicle gave no warnings, no steering correction, and no radar-based intervention prior to a severe crash. This failure of the safety systems placed my life at extreme risk. The vehicle had been properly serviced at an authorized dealer, and there were no warning lights or fault messages prior to the incident. After the crash, nearly all airbags deployed, but the crash data recorder shows abnormal timing information. The Bosch Event Data Recorder (EDR) captured a force of 292 G’s, confirming the severity of the impact. Dash camera footage also documents that the systems failed to intervene before the collision. My primary complaint is not about the airbags but about the malfunction of the lane assist and radar systems and the manufacturer’s refusal to provide the requested reports that would verify the failure. When I requested the radar and lane assist reports from the manufacturer after their inspection, they admitted they would not provide them. Instead, they stated there was no defect. This is unacceptable because the data clearly exists, and withholding it prevents owners from knowing whether these safety systems can be trusted. The fact that these systems failed in a critical moment and the manufacturer is unwilling to disclose the information raises a serious safety concern not just for me, but for all owners of this model. I can provide supporting materials upon request, including dash camera video, the full Bosch crash data report, and correspondence with the manufacturer. My concern is both the malfunction itself and the lack of transparency. Without access to the radar and lane assist data, owners cannot verify that the advanced safety systems they rely on are functioning properly. This failure and refusal to provide proof of system performance must be addressed to protect other dri INFORMATION REDACTED PURSUANT TO THE FREEDOM O

Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.

I leased a 2023 Audi A4 with 0 miles. At ~10,000 miles my car automatically shut down electronically I have photo evidence of this. This happened again recently at ~45,000 miles, I almost got into a severe car accident and possibly died. This happened on the highway driving in the left lane. I tried to remedy this situation before and was ignored by Aud's service center. I am scared I can die on the road and am taking in the car for repeat service tomorrow.
Since I bought this car in June 2023, I’ve had two instances where the presence feature malfunctioned when there was no danger of any accident. I’ve had one instance when all of the safety sensors illuminated at the same time while driving. Finally, this past Saturday, my car malfunctioned and died/ turned off while I was driving. It took a minute or so to get the car started. A malfunction notice illuminated. The area traffic is congested, so people honking at me but nobody hit me. Luckily, I was not on the freeway.

Purchased used 2023 Audi A4, driven less than 6 times, 30 days later with less than 36k miles the Safety Air Bag Scale & Sensor are illuminating as a "Warning" on the Display Panel" .....ALREADY! Cannot drive, Sunday, Service Centers CLOSED....SAFETY HAZARD to PASSENGERS if vehicle used. AUDI Parts need to be of better quality material for its "Brand", and Customer Safety.

Other / unspecified
Reports whose component NHTSA recorded as unknown, or that do not map to one of the categories above.

There currently exists a recall (24T-009) on the Continental ProContact GX AO 255/35R19 96H XL tire which was the OEM tire on some MY21+ Audi A4/A5s. The recall was the result of the compound used on the inner and outer edges improperly dissipating heat, resulting in premature wear, and belt breakage. I have a 2023 Audi A4, [XXX] which has the OE Continental ProContact GX AO 245/40R18 97H XL on it, and at 26,500 miles on the vehicle, all 4 of the tires require replacement due to significant wear on the inner and outer edges. All maintenance and service intervals were completed early or on time by the certified Audi Dealer. All 4 tires show normal and safe tread wear with the exception of the inner and outer edges. There are no known mechanical defects or issues with the vehicle, and the ADAS system functions properly and without issue, so there is certainly no alignment issue significant enough for a system fault. I am concerned that the Continental ProContact GX AO 245/40R18 97H XL tires suffer from the same defect as those in NHTSA recall 24T-009 and that if not replaced due to premature wear, will create a risk of injury and death.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
