Audi A5 vs Mercedes-Benz E-Class: Reliability Compared

On reliability, the Audi A5 comes out well ahead of the Mercedes-Benz E-Class. The deciding fact is volume: the E-Class has 184 recalls across eight model years to the A5's 16, and owners complain about it at more than twice the rate.

How Do the Audi A5 and Mercedes-Benz E-Class Generations Compare?

Most used shoppers will be looking at second-generation A5 cars (RE9), sold in the US for model years 2018 through 2024 with a refresh in 2022. The 2020 and 2021 cars in that run rank weakest. The third generation (RE10) began with the 2025 model year, so those cars are still new. On the Mercedes side, the fifth-generation E-Class (W213) ran from 2016 through 2023 and had a facelift in 2020. The sixth generation (W214) started with the 2023 model year. That places 2018 and 2019 as older, pre-facelift fifth-generation cars, and those are the E-Class years with the weakest standing.

Verdict

The Audi A5 is more reliable than the Mercedes-Benz E-Class, scoring 76/100 vs 60/100.

Reliability favors the A5 by a large margin. Federal recall records show 16 recalls across its eight model years, against 184 for the E-Class. Owners also file complaints at less than half the rate, 2.9 per 10,000 sold versus 7. The E-Class problems tend to be the kind that strand you: a dead 48-volt battery, misfires that trigger limp mode, and transmissions that failed at low mileage. The A5 has real faults too, but its biggest complaint area is a failing instrument panel rather than a car that will not move.

What Are the Common Problems With the Audi A5 and Mercedes-Benz E-Class?

Electrical trouble leads both lists, but it looks different on each car. A5 owners describe an instrument panel that blinks, then goes dark, taking the speedometer and warning lights with it. E-Class owners describe a 48-volt battery that dies early, sometimes before 1,000 miles, and leaves the car unable to start. One E-Class report involves a fire at idle. The E-Class also has complete transmission failures, misfires, and seat belts that will not retract. The A5's other issues include tire tread separation and Pre-Sense braking hard for no reason. Both models have crash-linked steering reports, and the E-Class also has crash-linked electrical reports.

Best years to cross-shop: The 2023 Audi A5 scored 81/100 and the 2023 Mercedes-Benz E-Class scored 63/100 — the strongest shared model years that have been on the road for at least two years, where available.

Who Should Buy the Audi A5 vs the Mercedes-Benz E-Class?

Pick the A5 if you want the lower chance of a surprise breakdown. Owner complaints and recall counts both run well below the E-Class. Target 2023, one of its strongest years, and be wary of 2020 and 2021, its weakest. If you test drive one, check that the instrument panel stays lit, since that is the most common complaint. Also look at the tires, and ask whether the Pre-Sense braking has ever fired without cause. Pick the E-Class only if the ride and cabin matter more to you than the odds of a repair, and you can live with a car that may sit waiting on parts. Skip 2018 and 2019, its weakest years. Its 2024 model year ranks among the strongest, though newer years have had less time to collect complaints. Before buying any E-Class, ask for proof that every open recall, including steering, was completed. Check the 48-volt battery history, and look for engine misfire records on the service history.

Audi A5 vs Mercedes-Benz E-Class: Common Questions

Is the Audi A5 more reliable than the Mercedes-Benz E-Class?
Yes, by a large gap. The A5 has 91 owner complaints (2.9 per 10,000 sold) and 16 recalls. The E-Class has 469 complaints (7 per 10,000 sold) and 184 recalls. The E-Class also has more reports of cars that will not start or move.
Which has more recalls, the A5 or the E-Class?
The E-Class, by a wide margin. Federal recall records show 184 recalls across its eight model years from 2018 to 2026. The A5 has 16 over the same span. Always check a specific car's VIN for open recalls before you buy.
What is the most common problem on the Audi A5?
Electrical faults, with 47 owner complaints. The typical report is an instrument panel that blinks on and off, then goes dark. That removes the speedometer and warning lights, and one owner's car sat unrepaired while the dealer waited on a replacement panel.
What goes wrong with the Mercedes-Benz E-Class 48-volt battery?
Owners report the 48-volt battery dying early, sometimes before 1,000 miles. The car cannot start or move and needs a tow. One owner waited more than three weeks for the replacement part. Some reports pair it with low 12-volt battery warnings and camera dropouts.
Which E-Class model years should I avoid?
Avoid 2018 and 2019, which are the weakest years for the E-Class. The 2024 model year ranks among its strongest, but newer years have had less time to collect complaints, so a clean record there is not proof of better reliability.
