2015 Audi Q7

Engine complaints dominate what 2015 Audi Q7 owners report, with oil consumption being the most recurring theme, drivers describe the engine burning or leaking oil at an unusually high rate, requiring frequent top-offs between oil changes, and in some cases reporting knocking sounds alongside the excessive consumption. A handful of owners also report emissions-related warning lights tied to the diesel exhaust fluid system, with error codes pointing to the catalytic converter or exhaust treatment components. Service brake and vehicle speed control complaints come in behind the engine category, though at lower volume. One pattern worth noting involves water intrusion through the firewall on the driver's side, which owners describe causing a wet accelerator pedal area, a symptom that shows up across more than one report rather than as an isolated incident.
