2020 Audi Q8

Complaints about the 2020 Audi Q8 center most heavily on the engine, with multiple owners describing catastrophic failures on the 3.0L turbocharged engine, specifically piston and cylinder wall damage that leads to complete engine lockup. Several owners also report excessive oil consumption as a related symptom. The engine failure pattern appears often enough that owners frequently mention Audi extending the engine warranty to 8 years or 80,000 miles in response. Electrical system complaints come in second, with owners describing sudden, complete power loss while driving, one pattern involves alternator failure causing the vehicle to shut down and lose power assist to the brakes. A smaller cluster of complaints touches on the fuel system, though those reports lack the volume of the engine concerns. Intermittent camera system failures round out what owners describe, with software updates providing only temporary relief before the problem returns.
