When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

Recalls on the 2023 Audi A4
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.

Airbag
Issue: On certain vehicles, the passenger occupant detection system may malfunction. This could cause the airbag system to turn off the passenger-front airbag even when a passenger is seated. Note: This problem would cause a yellow airbag warning light to turn on in the instrument panel. Safety Risk: An airbag that is turned off could increase the risk of injury to a passenger in a crash. Corrective Actions: Audi will notify owners by mail and advise you to take your vehicle to a dealership to replace the passenger seat occupant detection system control module.

LANE DEPARTURE: ASSIST
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.

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.

FORWARD COLLISION AVOIDANCE: WARNINGS
The vehicle erroneously applies sudden emergency braking (Audi Pre Sense) without conditions warranting system activation. This malfunction occurs at the most dangerous of times, mostly while making left turns. Vehicles behind do not expect the vehicle ahead to suddenly stop which is going to cause an rear-end collision, and the timing for turning across lanes of traffic is leading to the potential front-end collision with opposing traffic. The sudden activation is unbelievably jarring and has caused shoulder and neck pain. This matter has been brought to the attention of the dealer on multiple occasions but codes are not produced for activation and I was told there is no "black box" to look at data history. This issue has been brought to the dealer's attention on 6/1/24, 12/21/24, & 1/2/25. The most recent incident occurred on 4/30/25 at approximately 2:00 P.M. during the same condition of making a left turn.

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.

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.

My brand new car stalled in the middle of traffic; as I proceeded to step on the gas peddle after yielding -- the car completely stoped as is I hit a wall, it jerk roughly and completely stopped. At first I thought someone rear-ended me, but that wasn't the case, the car just stalled, and the "Audi Pressure Sensor" warning flashed across the screen in Bright Big Letters for a few seconds, and once the waring went away, the car turned back on. This event happened twice, about 40 days apart. My life was at risk because if I was on the expressway, the complete stop of vehicle could have cause an accident. The car completely stoped, it doesn't slow down, it just stoped roughly, very dangerous situation. I called the dealer and I have an appointment in 2 days, meanwhile I won't take the car on the expressway, or drive it if I don't have to. I'm frighted the 3rd time I won't be so lucky and someone may hit me from behind.

"Locked doors make it more difficult for emergency workers to enter the vehicle, which puts lives at risk." This quote is from the warning on page 40 of the Audi owners manual. I do not wish to drive wth the doors locked for this reason, yet the Audi computer automatically locks the doors every time the car exceeds about 10 MPH. The local dealer was unable to reprogram the vehicle to turn off auto lock. After consulting with tech support, they said it is not possible to turn off auto lock. I strongly believe there needs to be a software upgrade to correct this vehicle deficiency. Owners must be permitted to drive with the doors unlocked so if we are involved in a collision bystanders and/or emergency personnel may assist us.
