2019 Audi Q7 driver assistance problems

Filed Mar 30, 2026 · Brakes, Driver assistance · NC

My car has experienced unintended automatic emergency braking while driving in active traffic with no obstruction present. This created a serious risk of a rear-end collision from vehicles behind. Prior to this, the car had ongoing alignment and steering issues beginning shortly after purchase. The car consistently pulls while driving and has required multiple repair attempts, including alignments and inspections of steering and suspension components. These repairs have not resolved the issue. The problem appears to be worsening. In addition to the unintended braking, the vehicle intermittently displays safety system warnings related to driver assistance features. The failure involves both mechanical and electronic systems, including steering alignment and automatic emergency braking. It's believed that incorrect alignment or suspension issues may be affecting sensor calibration and causing false collision detection. The car has been inspected multiple times by the dealership, but the issue has not been diagnosed or permanently repaired. The car's unsafe to operate due to unpredictable braking behavior. The warning signs that the car gives are “Traffic jam assist unavailable” and “Safety system malfunction” while driving.These warning messages and system malfunctions have been occurring intermittently since shortly after purchase in early 2025 and were previously reported to the dealership. The warnings continued after the incident and are documented with photos taken the following day. The safety systems appear to be unreliable and malfunctioning in real-time operation.

The auto brake suddenly braked hard and it was scary. The car reported a collision warning red light for a few seconds. Luckily, there was no car close behind me. While I was driving at about 70 miles per hour on the highway, there was no car in front of me to worry about. There was probably a car driving in the next lane. After the sudden brake, everything seemed to be back to normal. This type of sudden auto brake happened once in late 2019, on a local drive, I thought it was a falling leaf or something. But this time on the highway, there was nothing in front the car.

The problem occurs when making a left-hand turn. I'm in the left-hand turn lane waiting for oncoming traffic to clear. When it is clear, I proceed with my left-hand turn. After a short distance, the Forward Collision Warning indicator flashes, the brakes are applied very hard, and the car stalls. I am often left in the oncoming lane, with a stalled car. I have to put it in park, start it then put it into drive to move forward again. This takes a bit of time. This is 1) very startling, 2) makes it likely for me to be rear-ended, and 3) my car can easily be hit head-on by a car in the oncoming lane. I luckily have not been in an accident yet. This has occurred at least 5 times, with one additional time, the indicator and brakes being applied but the car did not stall. The dealer has been notified twice about this problem, and says there is no known solution they know about. This is a very serious problem. In all instances, there are NO cars in sight in the oncoming lanes. These are all false alarms. The fact that there has not been a read-end collision yet is very surprising.

I was going approximately 55 miles per hour in the center lane on the interstate. Shortly after shifting the car into sport mode, the vehicie had sequential malfunction notifications appear on my screen. The specific order is difficult to remember due to the rapidness of the whole situation. The malfunctions appearing on the screen over the steering wheel were: traction control malfunction, TPMS (tire pressure monitoring system malfunction, parking brake malfunction, automatic start/stop system: malfunction, start/stop system: malfunction, and a drive system: malfunction. The majority of these warnings said to please contact service. While the malfunctions appeared the engine of my car stopped working, acceleration stopped working, and the engine did not maintain the current speed. The vehicle essentially died at highway speed while I was travelling in the middle lane. I turned on my hazard lights and was able to coast to the shoulder (after other drivers allowed me over). Once stopped I turned off the car, pressed the start/stop button which resulted in a repeat of the start/stop malfunction indicator, and it instructed me to 'manually start'. I then pressed the button off and back on again, the car then restarted. The car shifted into drive and I took it immediately to the local audi dealership.
