NHTSA Complaint #11618378 — 2023 AUDI Q5

3 times this vehicle did not try to stop in time to keep from rear ending a vehicle. The imminent crash warning would come on but the vehicle did not try to stop. This model is supposed to apply the brakes on its own to keep from rear ending someone but it did not apply brakes. If I hadn’t taken hard and immediate braking action we would have rear ended vehicles. The vehicle has an $5800.00 option to brake in emergency situations. There have been at least 3 instances where the vehicle will not engage with lane keeping attempts while being on. This vehicle will also not notify the driver that the vehicle is leaving its lane even though it has lane keeping technology options turned on and purchased.
