What is the most reliable Audi model?

The Audi A4 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.
