Top-Rated 2021 Luxury Cars in Quality According to Consumers

Christian Wardlaw | Aug 31, 2021

Luxury cars aren’t vanishing from the market to quite the same extent as those sold by mainstream brands, but buyers of more expensive vehicles are similarly migrating to SUVs in significant numbers. Nevertheless, the small, midsize, and premium midsize car segments offer numerous excellent choices, as evidenced below on this list of the top-rated luxury cars in quality.

Verified owners of the makes and models on this list provide J.D. Power with the information on which the rankings are based. Each year, J.D. Power surveys tens of thousands of people who bought a new vehicle and have owned it for at least 90 days, asking them about problems they’ve experienced during the initial ownership phase. This information forms the basis for the data compiled in the annual J.D. Power Initial Quality Study (IQS).

As a part of this data synthesis, J.D. Power assigns every make and model that meets minimum sample size requirements a “problems per 100 vehicles” (PP100) score. The lower the PP100 score, the higher the quality.

Listed below, according to the consumers who own them, are the four-door luxury cars offering the best quality across three different segments. They’re shown in descending order by PP100 score, putting the highest-quality model at the bottom of the list.

Note that we’ve got a separate list of coupes and convertibles that also contains luxury models, if you prefer those body styles.

Lexus offers the ES with a four-cylinder (ES 250), a V6 (ES 350), or a gas-electric hybrid powertrain (ES 300h). The ES 250 is new for 2021 and includes AWD, while other ES models are FWD.

Infiniti’s only sedan lives between traditional compact and midsize models. The Q50 traces its lineage to the critically acclaimed G35 and G37 sedans, switching to the Q50 nameplate when the car was last redesigned for the 2015 model year.

Don’t look for the venerated VQ-series V6 engine under the modern Q50’s hood. Every version of the car has a smaller displacement twin-turbocharged V6 driving the car’s rear wheels. An AWD system is optional, and the Red Sport 400 is more powerful, offering more than a 30-percent increase in output for speedy acceleration.

For 2021, Infiniti adds new Sensory and Signature Edition trim levels to the 2021 Q50 lineup, slotting them between the Luxe and Pure at the lower end and performance-oriented Red Sport 400 at the top.

Critically acclaimed, the Genesis G70 achieved its goals, but without a habitable rear seat or a sizable trunk.

Two model series are available. The G70 2.0T has a turbocharged four-cylinder engine, while the G70 3.3T employs a twin-turbocharged V6. A manual gearbox is available, but Genesis has announced that the stick-shift is canceled for 2022. The engines power the rear wheels unless you opt for AWD.

Aside from dropping the manual transmission mid-year, Genesis also simplified the lineup for 2021.

The IS 300 AWD switches to a 3.5-liter V6 and four driven wheels. The IS 350 also has a 3.5-liter V6, but it makes 51 more horsepower sent to the rear wheels unless you specify AWD.
