2021 Audi Q5 Reliability Score & Common Problems

Owners of the 2021 Audi Q5 frequently report issues with the vehicle's forward collision avoidance systems, particularly the Audi Pre Sense feature, which falsely activates emergency braking without clear cause. Typical symptoms include sudden braking at high speeds or while stationary, forceful seatbelt retraction, and unexpected system engagement, often leading to near-collisions and physical discomfort. These incidents occur at various speeds and under different conditions, with some reports highlighting repeated occurrences over several months. Safety implications are significant, as unexpected braking can lead to rear-end collisions or physical injuries to occupants. Additionally, improper calibration of ADAS systems following repairs is noted, which may compromise the functionality of safety features like adaptive cruise control and lane change assist. These patterns suggest potential risks for buyers considering a used Audi Q5.

Owners of the 2021 Audi Q5 report issues with the vehicle's backup camera and MMI screen, which can randomly stop working or display incorrectly, with no prior warning signs, affecting both reversing and forward driving. Complaints frequently mention the sunroof unexpectedly exploding and the climate control buttons popping off, potentially posing a safety hazard if small parts become loose inside the vehicle. Additionally, some owners describe unintended emergency braking triggered by the Audi Pre Sense system, occurring without clear obstacles, thus increasing the risk of rear-end collisions. These issues appear to occur in relatively new vehicles, with problems reported as early as within the first year of ownership.

Owners of the 2021 Audi Q5 report issues related to steering, with one complaint involving a crash and injury. Common symptoms include the steering wheel locking up during driving, as well as forceful and sudden jerking to the left. One owner describes a steering failure alongside multiple system errors due to a failed Gateway control module, previously subject to a recall. These issues can lead to a complete loss of steering control, posing significant safety risks. The problems are reported at various times, with one incident occurring after a recall repair was deemed insufficient, highlighting potential ongoing concerns for used car buyers.

Owners of the 2021 Audi Q5 report issues related to wheel components, specifically involving a recall for the rear axle trailing arm lock nut and unexpected tire wear. One owner indicates difficulty with a dealership refusing to perform the recall repair unless additional paid services are scheduled, while another owner describes premature tire wear at approximately 13,000 miles, which was not covered under warranty by Audi or the tire manufacturer, Kumho. These complaints highlight potential concerns with dealership service practices and tire durability, with no safety incidents such as crashes or loss of control reported. Buyers should be aware of these issues, especially regarding recall service conditions and tire warranty coverage.

Owners of the 2021 Audi Q5 report issues involving the fuel system, specifically related to fuel leakage. One complaint describes a gasoline leak resulting from the gas tank being pierced by a piece of metal on the road, which poses a potential fire or explosion hazard. Another owner mentions gasoline dripping from the right rear passenger area while the vehicle is parked, attributed to a faulty fuel pump as diagnosed by a service center. This issue is accompanied by a fuel system warning light and a previously replaced gas cap gasket. While specific mileage is not mentioned, the safety implications include risks of fire due to fuel leakage. These reports suggest potential concerns for used car buyers regarding fuel system integrity.

Owners of the 2021 Audi Q5 report issues related to the fuel system, primarily involving the fuel tank and gauge. One owner describes a situation where the plastic fuel tank was damaged after driving over debris, resulting in a fuel leak. Another owner reports a malfunctioning fuel gauge that inaccurately indicates a full tank even when nearly empty, with this issue occurring around 5,000 miles. These complaints highlight potential safety risks due to fuel leakage and the inaccurate fuel level reading, though no crashes or fires are reported. These issues appear relatively early in the vehicle's life, between 5,000 and 9,000 miles.

Owners of the 2021 Audi Q5 report issues with the sunroof shattering unexpectedly while driving. Complaints frequently mention a loud booming sound followed by the sunroof glass breaking, with one incident occurring at approximately 4,000 miles and another at around 51,000 miles. In both cases, the shattered glass posed a safety risk by entering the vehicle's cabin, although no crashes or injuries were reported. These incidents suggest potential safety implications, particularly concerning driver distraction and injury from falling glass. Buyers considering a used 2021 Audi Q5 may want to inquire about the sunroof's condition and any related repairs.
