Engine mount fluid leaks are also commonly mentioned, with reports indicating occurrences around 44,000 to 100,000 miles. Another recurring issue involves the vehicle's backup camera system unpredictably switching modes, requiring manual intervention to restore the desired view. Safety implications are noted in several complaints, particularly concerning the sunroof explosions and potential child safety lock malfunctions, which could trap children inside the vehicle. These patterns suggest potential concerns for prospective buyers, particularly regarding costly repairs and safety risks associated with these issues.

Owners of the 2018 Audi Q7 frequently report issues with the vehicle's electrical system, particularly involving the MMI system and lighting components. Multiple complaints describe the MMI system shutting down and restarting unpredictably, affecting navigation and other vehicle settings, with some reports indicating increasing frequency over time. Additionally, several owners mention recurring problems with the side marker lights, often referencing previous recalls that did not cover their specific VINs. Reports also highlight safety concerns, including instances where the vehicle unexpectedly runs out of fuel due to a faulty fuel level sender, and issues with the driver assist system, such as the pre-sense feature engaging brakes abruptly. These problems are noted across various mileage ranges, with some occurring as early as 42,000 miles, and pose potential safety risks, including unintended vehicle stoppages and the risk of being stranded.

Owners of the 2018 Audi Q7 report several steering-related issues. A common problem involves the steering wheel malfunctioning or seizing, often accompanied by warning messages, which can lead to loss of control and necessitate towing, as noted at mileages around 60,000 to 65,000 miles. Additionally, some owners describe a misalignment between the steering wheel and driver seat, and steering drift towards the passenger side, which is linked to tire wear issues. Safety concerns are highlighted by instances of steering failure during driving, with one report involving a collision with a curb. These complaints suggest potential safety implications for prospective buyers to consider.

Owners of the 2018 Audi Q7 frequently report issues with the power train, particularly involving sudden loss of power and transmission malfunctions. Common symptoms include unexpected deceleration, the vehicle stalling or being stuck in neutral, and dashboard warnings such as “Drive System: Malfunction” and “Transmission Malfunction.” These issues often occur at higher mileages, such as 59,000 miles, but have also been reported in vehicles with as little as 7,000 miles. Safety implications are significant, with owners describing scenarios where the vehicle loses power on highways or during turns, potentially leading to hazardous situations. Additionally, some owners mention differential noise and oil consumption issues, which may further affect vehicle reliability.

Owners report frequent issues with the brakes on the 2018 Audi Q7, with the most common complaint being a loud squeaking noise, particularly when reversing. This noise is described as alarming to both the driver and surrounding individuals. Several complaints indicate that this issue becomes noticeable at mileage as low as 20,000 to 27,700 miles. In some instances, owners have reported that dealers initially did not inform them of a relevant Technical Service Bulletin (TSB) and suggested costly repairs instead. Additionally, one owner mentions a brake lock-up at low speeds on icy roads, indicating a potential safety concern. Used car buyers should be aware of these brake performance and communication issues when considering this vehicle.

Owners of the 2018 Audi Q7 frequently report issues with tire wear and performance, particularly with run-flat tires from various manufacturers including Pirelli, Goodyear, and Continental. Complaints commonly describe uneven tire wear, with patterns such as "chunking" on outer edges and "wavy" wear on the inside, often appearing as early as 7,000 to 14,000 miles.
