2023 Audi A4 Common Problems by Component
8 owner complaints grouped by vehicle system.
ELECTRICAL SYSTEM
3 complaintsOwners of the 2023 Audi A4 report several issues with the electrical system. A recurring problem is the vehicle shutting down unexpectedly while driving, with incidents noted around 10,000 and 45,000 miles, posing a potential safety risk, particularly on highways. Additionally, there are reports of malfunctioning safety sensors and erroneous activation of the presence feature, which can cause confusion and distraction. Another reported issue involves the automatic door locking system, which cannot be disabled and may hinder emergency access to the vehicle. These complaints suggest potential safety implications, such as loss of control or difficulty in emergency situations, which prospective buyers should consider.
BACK OVER PREVENTION
1 complaintThe 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.
WHEELS
1 complaintThere 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.

ENGINE (1 complaints)
ENGINE
1 complaintMy 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.
LANE DEPARTURE (1 complaints)
LANE DEPARTURE
1 complaintSafety-relatedWhile 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 OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

How We Calculate Reliability Scores
Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.
Key Ranking Factors
Complaint Severity
NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.
Repair Costs
Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.
Recall Impact
Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.
Issue Diversity
Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.
Scores are grouped into four tiers:
- 80–100: Excellent — Top-tier reliability, minimal issues
- 60–79: Good — Reliable with some minor concerns
- 40–59: Mixed — Notable issues, research before buying
- 0–39: Risky — Significant problems, proceed with caution
Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
