What is the most reliable Audi model?

The Audi A4 (sold as the A5 sedan from the 2025 model year) and Q5 consistently rank as the brand's most reliable models. Both use Audi's well-proven 2.0-liter turbocharged four-cylinder engine and have simpler tech layouts compared to the A6 or Q7. The Q5 in particular has earned above-average reliability scores from J.D. Power and Consumer Reports in recent model years. Avoiding the first model year of any redesign is a good general rule with Audi.
