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.

Below are a few of the circumstances where my 2023 Audi A4 pre-sense, indiscriminately slammed on the brakes. Sometimes the warning message appeared, but not always: 1) Getting ready to get on highway from a high, descending ramp, no cars in front of me. The closest car in front of me was on the opposite side of the ramp, quite a distance from me. As soon as I attempted to move forward, my car slammed on the brakes. The vehicle behind me had to slam on their brakes to avoid rear-ending me. 2) In rush hour traffic, cars bumper to bumper. I left half a vehicle space in front of me, but my car still randomly braked hard. 3) Backing out of a parking space, vehicles parked to the side of me, no vehicles in front of me and no vehicles passing on the road behind me. In the middle of backing out, the car brakes so hard, it shook everyone in the vehicle and stalled. 4) I was in the center turn lane at the bottom of a slight hill. There were cars to the right side of me at the top of the hill. I had more than enough time to cross but, while crossing the lane, my car did a hard brake and stalled. The cars coming from the top of the hill were headed toward me and I had to quickly restart the car. This seems to be a known issue according to Audi users: From an Audi Group Site: "Audi Pre Sense can sometimes misinterpret driving situations, leading to unexpected braking or safety interventions, which may cause accidents rather than prevent them. Issues can arise from sensor misalignments or software glitches, and persistent problems may require professional diagnosis."
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.

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.
From owner reports, verbatim
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.
