Twice in 2019 my car slammed to a stop while backing up at 2-3 mph. I had not hit anything and no damage to car. There was nothing to hit, just a vacant area. Yesterday while driving forward at 35-40 mph on a main street with the closest oncoming car 1 block away my car slammed to a dead, wall slamming stop. If a car had been behind me there would have been an accident. I emphasize: This was a dead, no slow-down stop. I refused to drive it 50 miles to the dealer. The dealer has picked it up and told me the sensors were set too sensitive. If so, why did this not occur every time I drove? frankly, I am afraid I will be forced to drive this car for the next 3 months until my lease expires. The dealer will not give me a loaner. I think this is a very unsafe car. I have no confidence in the way this is being handled. For your interest, I was given a ride today in the 2019 sedan model. Unbelievably it slammed to a stop while backing out of my driveway.

On multiple occasions when driving the Audi Q5 the pre-sense engages inappropriately (no trigger) resulting in an immediate and harsh braking of the car to a complete stop. In traffic, this poses a significant risk of a crash resulting in damage and potential bodily injury. The Audi pre-sense is designed to stop a car from an imminent crash, however an apparent flaw in the technology engages the pre-sense without totally unnecessarily (no cross traffic, at least 10 feet from a bush or other object). Not only does the unexpected and unnecessary hard auto-braking add wear and tear to the brakes and suspension, it poses a real risk of an accident as other drivers do not expect the sudden and unnecessary braking. This happens intermittently without a pattern in dry and wet weather on a flat surface or an incline. Always occurs when in reverse.

While driving down the expressway in Chicago, transmission, and all safety features completely shut off. Pressing on accelerator had no effect, and with limited steering was able to pull to roadside barely missing high-speed traffic. Expressway roadside is narrow, so was nearly hit by many cars while waiting for tow service. Car would not restart and with full electronic transmission, no ability to put into neutral. Audi roadside assistance did not provide timely tow service. Extremely dangerous and unsafe.
