Although interest in midsize sedans has migrated to crossover SUVs, that doesn’t mean people don’t buy them anymore. For instance, Toyota sold nearly 300,000 Camrys in the U.S. last year. One of the reasons why the segment remains popular is its class-wide dedication to reliability. The following four midsize four-door cars didn’t just breach the all-important 200,000-mile threshold; they went much farther.

1. Toyota Avalon  

Although the higher-riding Toyota Crown replaced the Avalon, that doesn’t mean it was cut for reliability concerns. In fact, a recent study found it’s the longest-lived of all sedans made within the past two decades. With its tried-and-true front-wheel drive V6 drivetrain, at least 1% of Toyota Avalons have clocked 245,710 miles.

The figures come from iSeeCars, which analyzed over two million vehicles on the road. The automotive research agency used models that were in production for at least 10 of the last 20 model years. Unfortunately, the high praise came just as Toyota retired the nameplate. But used car buyers are in luck for a Lexus-inspired mass-market sedan with extraordinary reliability. 

2. Chevrolet Impala             

The Impala was killed off by General Motors in the 2020 model year. While the base four-cylinder proved to be a wheezy powertrain, it could be staffed with a robust V6. Not only did it provide plenty of power, but it also had immense dependability. The study indicated that the Impala has a potential lifespan of 230,343 miles.

The mileage determinations are not so much technical analysis but odometer readings of owner cars. Regardless, the proof is in the pudding, or rather, it was. Chevrolet, and the U.S. itself, makes just one lone American-branded sedan now, the Impala’s baby brother Malibu.

3. Honda Accord   

Of course, there’s a Honda. Many would have been surprised not to find one. The study found that at least 1% of all Accords built since 2003 have indicated 226,168 miles on their odometers. Fortunately, the Honda Accord is still in production.

The newest generation Accord boasts some of the best styling in the vehicle’s history. Although it only has 1.5 liters under the hood, many praise the five-seater for its dynamic road performance. Its turbo-four and state-of-the-art tech may introduce some dependability-adverse complexities, but Honda established a pattern of reliability long ago.

4. Toyota Camry   

You may have been wondering where this one was. The Camry is the best-selling sedan in America. Even though it’s fifth on the list for GoodCarBadCar’s 2022 U.S. auto sales analysis, it’s been a perennial favorite.

Toyota’s Camry had the Avalon drivetrain in the top-tier models, but the base four-cylinder displayed similar reliability. Over the last 20 years, 1% of all Camrys—3.5-liter V6 or not—achieved 223,249 miles. Given its popularity, it’s likely that the automotive world may never see the end of the nameplate—in America, at least. The Camry was killed off in its home country of Japan after 43 years of production.

What’s the most reliable midsize sedan today?

Interestingly enough, it may not be the Accord or the Camry. They have a challenger from across the Korea Strait.

In the J.D. Power 2023 Vehicle Dependability Study, Kia was ranked as the most dependable brand. Among the mass-market brands, Kia led Chevrolet, Mitsubishi, and Toyota. The automotive analysis agency gave a brand-wide score of 152 Problems per 100 (PP100) vehicles. Comparatively, Chevrolet ranked second in mass-market brands with 162 PP100, and Toyota came in fourth with a score of 168 PP100.

Where was Honda? Surprisingly, Honda is much further down. On the mass-market list, it’s 13 places below the top with a 205 PP100 rating; the industry average was 186 PP100. Therefore, as time passes and Kia continues to increase their quality, it’s likely its sedans will last far beyond 200,000 miles.
