2019 Audi Q7 Reliability Report

A string of warning messages floods the dash, and then the engine stalls at speed. Some drivers also lose power steering and power brakes, at speeds ranging from 55 to 90 mph. In some cases the car restarts and runs normally until it happens again. Other reports describe a failed starter that leaves the car unable to start, and an infotainment screen that freezes and reboots while driving, hiding navigation and warnings. A false right parking lamp fault also appears, with a dealer quoting a full headlight replacement at over $2500. One complaint is crash-related.

Sunroof glass shatters while driving with nothing hitting it, raining glass onto the people in front. One report describes a pop at 55 to 60 mph before the panel burst. The center screen freezes over and over when using Apple CarPlay for navigation, and the route is lost when the phone is reconnected. Doors can lock by themselves with the key and a child inside, and the rear doors cannot be unlocked from the back seat. The backup camera goes blank or doesn't turn on.

Throttle response lags 3 to 4 seconds after the gas pedal is pressed, and one lag ran about 6 seconds. Then the car lunges forward. It happens most at low speeds, when merging, and when turning left across traffic, and it has led to near collisions. Dealers report no fault and can't reproduce it. Separately, one car would not shift into Park and then locked its doors with a child inside at 5,765 miles. Another needed a new transmission control unit at 45K miles and had leaking engine mounts by 48K.

Front tires wear out early and badly. Tread peels, chops, or tears off across the whole tire while the rears still look new. Damage appears as early as 11,900 and 19,600 miles, and at 49,520 one dealer found chopped inner edges. Complaints center on the factory Goodyear Eagle Sport run-flat tires in size 285/45-20. One dealer pointed to a service bulletin on front tire wear but billed the owner for tires and an alignment. Owners note that tire rotations are not part of the scheduled maintenance.

Automatic emergency braking slams on the brakes when nothing is ahead, sometimes bringing the car to a full stop on the highway. One case happened at about 70 mph with an open road ahead. Left turns are another trigger. The forward collision warning flashes, the brakes grab hard, and the engine stalls, stranding the car in the oncoming lane until it is restarted. One driver reports this at least 5 times. The risks described are rear-end crashes and head-on hits.

The coolant pump leaks or fails between 49,520 and 60,000 miles, and one report blames a bad bearing with too much play. A low coolant warning at startup is the first sign, even when earlier coolant checks looked normal. One failure was fixed under warranty, and the owner says the repair would have cost $1500 otherwise. The reports describe no overheating or engine damage.

A "right front parking light defective" or "side marker light faulty" message appears and won't go away. It shows up every time the headlights come on, even when the light seems to work. One report puts onset at about 60K miles. Repair quotes run $3000 to $5000 because the fix involves the headlight assembly, though the faulty part costs about $30. Some owners disable the light with diagnostic tools instead, which removes a required safety light.
