2024 Audi Q5 Driver Assist & ADAS Problems

The system continues to sound an alarm and flash a warning that lane departure and collision is malfunctioning. We took it to the dealership, they told us two things: it may be a software glitch but they couldn’t recreate it and all systems are normal currently. We live 2.5 hours from the dealership and had to take the day off, rent a vehicle during the repair because no loaner was available. We started our return trip, the vehicle sounded the warning an additional three times yesterday and then again today 3 more times by lunch.

Audi has a pre-sense mechanism that cannot be permanently turned off. I have almost been hit three times when the Audi brakes FOR NO REASON at all; people almost rear-end me because the Audi comes to an immediate halt. And there is no reason for the pre-sense to engage when it does go off. They are flukes. I am going to get seriously injured.

Vehicle had 2000 miles on it when warning messages of Distance warning unavailable and Audi pre sense limited with beeping signal sounding every few miles. The dealership confirmed the issue but only blamed a dirty sensor for the issue.The problem persisted even with cleaned sensor for another 6 thousand miles of driving after which I got an active lane malfunction warning. Since then all the warning messages and beeping stopped, but also the pre sense, and lane monitoring no longer work. Paid extra money for these extra safety features but they are not working.

Audi pre sense has applied the breaks and cause dangerous situations a total of three times. This occurred twice within the first six months I had the car. I made a left turn and the car suddenly stopped in the intersection and applied the brakes with great force that I was jolted quite hard. I brought the car into an Audi dealership and they adjusted the Audi pre sense settings to be less sensitive but the issue happened again recently. The situation was the same where the brakes suddenly were applied while I made a left turn leaving me standing still in an intersection with oncoming traffic headed at me. It is not possible for Audi to completely turn off the pre sense system, the driver would have to do so each time they start the car which isn't realistic. I believe there needs to be a recall. I feel unsafe.

Component/System Malfunction: The Audi Pre-Sense system has malfunctioned on multiple occasions. The system is available for inspection upon request. What Happened: On two separate occasions, the Pre-Sense system erroneously activated while making an unprotected left turn at a signal-controlled intersection. In both instances, the left turn signal was activated. After waiting for an oncoming vehicle to pass, I began the left turn. Despite the vehicle having passed, the Pre-Sense system activated, incorrectly perceiving the passing car as a threat. The system abruptly engaged emergency braking, locking the car in place and stalling it in the middle of the intersection. This left my two minor children and me stranded in oncoming traffic, creating an immediate and severe safety hazard. On a separate occasion, while driving straight in a lane with no intention of turning, the Pre-Sense system activated again. This time, the vehicle next to me slowed to make a left turn in its lane, which triggered my car's system to abruptly stop and stall in traffic. Risk to Safety: These malfunctions placed my family and other road users in immediate danger of a collision. In the left-turn incidents, the car stalled in the middle of an intersection with oncoming traffic approaching. In the straight-driving incident, the sudden stop created a risk of being rear-ended in traffic. Attempts to Resolve: After the first two incidents, I brought the vehicle to the dealership for inspection. A full diagnostic test was conducted, and I was told the Pre-Sense system was functioning "properly" with no repairs needed. Dealership staff admitted they had experienced similar Pre-Sense malfunctions in their own vehicles but dismissed the issue. I was advised to ensure my left turn signal was activated, despite already confirming the signal was on during both incidents. Warning Lamps or Symptoms: There were no warning lamps, messages, or other symptoms of the problem before the failures occurred.

While starting a left turn from the center left turn lane the car abruptly and forcefully applied the brakes and placed itself in park. There was a single vehicle in the oncoming lane of traffic but it was a more than sufficient distance away to allow the turn to be completed safely. We had not yet left our own lane and there was no risk of collision as a result of the incident. There was no warning from the vehicle prior to the event taking place and after the incident took place a Pre Sense warning was displayed on the dash. We were quite disoriented after the incident and it was several seconds before we realized what had happened. My passenger complained of not feeling well after the incident and still does not feel well several hours after it took place. The vehicle has not been taken for any inspection at this time. We found the option to disable Pre Sense in the Audi MMI settings and have since driven the car with the feature disabled, but it has to be disabled every time the car is restarted.

In addition to our complaint #11608543, filed on 8/14/2024, we are submitting a new and different safety concern today. While driving our new 2024 Audi Q5 with the adaptive cruise control set at the speed zone limit (55 mph), the cruise control adjusted itself down to 20 mph. The adjustment from 55 to 20 is sudden and extremely abrupt with some braking being applied. NO advanced warnings or discernible causes for the speed reductions were observed. If another driver had been following us, we likely would have experienced a rear end collision. We have experienced this malfunction on [XXX], east of Carroll, IA, and 1 to 1-1/2 miles north of [XXX], traveling in both the north direction and south direction. We have visited with the dealer numerous times. The dealership has hooked the vehicle to a diagnostic device and has reported to us that "the vehicle is performing as intended". We have submitted a claim with national Audi customer service representatives and they ruled that "if the dealer says that it is performing as intended", they have to deny our claim. Initially they offered "a gift" in compensation to us. We vigorously refused and stated that our goal was to have the vehicle fixed so it works properly or to have it retired from service before someone gets injured.

The contact owns a 2024 Audi Q5E. The contact stated while driving at approximately 35 MPH, the Lane Keep Assist erroneously corrected the steering wheel, causing the vehicle to make a drastic right turn onto a side street. The contact stated that the failure had been recurring mostly while driving near a turn lane or a side street located on the left or the right sides of the vehicle. The contact stated that there was a message advising the driver to take control of the vehicle displayed after the failure. The vehicle was taken to a local dealer but was not diagnosed or repaired. The manufacturer was informed of the failure and the contact was advised that the failure was a known software failure. The failure mileage was 9,589.

We were driving on [XXX] at the posted speed limit of 65 mph. The adaptive cruise control was activated and the predictive control turned on. We drove past a [XXX] sign and the car abruptly decreased speed down to the twenties. Had another car been following us, we could have been rear-ended. We soon encountered a speed sign posting a 65 mph limit and the car quickly accelerated to that speed. We felt totally unsafe in this surprise car behavior. This car behavior has happened on numerous occasions, as we travel that area often. We have had numerous discussions with the Audi dealership and they say that they cannot find cause/offer help with our safety issue. We have several videos documenting this safety issue.
