NHTSA lists 5 safety recalls and 25 owner complaints for the 2018 Audi SQ5. Most complaints involve electrical system (8) and engine (7). The EPA rates it 21 mpg combined.
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2018 Volkswagen Atlas, Passat, Beetle, Beetle Convertible, Golf, Golf SportWagen and GTI and Audi Q5 and SQ5 vehicles. The brake caliper pistons on these vehicles may have insufficient coating, potentially reducing the brake performance.
Volkswagen Group of America, Inc. (Audi) is recalling certain 2021-2022 Q5 Sportback, SQ5 Sportback, 2018-2022 Q5, and SQ5 vehicles. A liquid spill in the rear seat, or water ingress from an insufficient body seam underneath the vehicle may allow liquid to penetrate the gateway control module, causing it to shutdown.
Volkswagen Group of America, Inc. (Audi) is recalling certain 2018-2019 Audi SQ5 and 2018-2020 Audi Q5 vehicles. The rear wheel arch cover trim may loosen and detach from the vehicle.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“I purchased my 2018 Audi SQ5 on September 12, 2025, from Audi Denver (McDonald Automotive Group). On XXX, at 114,145 miles, the vehicle suffered a sudden, catastrophic engine failure while driving on the highway near [XXX], caused by defective rocker arm needle bearings in the 3.0T EA839 V6 engine. The early-design needle bearings disintegrated within the cylinder head, scattering loose metal roller bearings into the valvetrain and oiling system. This caused an immediate, complete loss of engine power and sudden engine lockup on a remote stretch of highway. This mechanical failure created a severe driving emergency. The sudden engine seizure stranded us on the shoulder, resulting in a total loss of propulsion, loss of vacuum assist for power braking, and potential loss of power steering—posing a severe risk to vehicle occupants and surrounding highway traffic. The vehicle required an initial tow off the highway in [XXX], followed by a second tow of nearly 200 miles back to [XXX]. Professional diagnostics confirmed complete engine destruction due to valvetrain failure, with repair estimates exceeding $20,000 for an engine replacement. Because the repair cost…”

“While driving a 2018 Audi SQ5 with the EA839 3.0T engine, a coolant warning light activated and engine temperatures began rising to 210-215°F. The vehicle was pulled over immediately. Upon inspection the coolant reservoir was found to be nearly empty with dried coolant residue on the exterior indicating an active leak. The vehicle was towed to an authorized Audi dealer who confirmed via multi-point inspection that the water pump, shut off valve, and vacuum system require replacement due to coolant leakage, with a repair estimate of $5,324.87. This is a known defect in the EA839 engine platform. Audi has issued multiple Technical Service Bulletins on this issue and is currently named in active federal class action lawsuit Larr et al. v. Volkswagen Group of America, Case No. 2:26-cv-05678. The vehicle was confirmed by the authorized dealer and the component is available for inspection.”
