Most Reliable Sedans

Reliability ratings for sedans are calculated based on analyzing over 12 million vehicles to assess a model’s long term durability.

The most reliable small and compact car is the Honda Civic (9.1 reliability rating), with the Lexus IS 350 being the most reliable luxury small and compact car (8.9 reliability rating). The Honda Accord ranks #1 for the most reliable midsize cars (9.0 reliability rating).

The most reliable luxury midsize car is the Lexus ES 350 (8.9 reliability rating) and the most reliable large car is the Toyota Avalon (9.8 reliability rating). Topping the list for the most reliable luxury large cars is the Mercedes-Benz S-Class (8.7 reliability rating), while the Toyota Prius ranks first for the most reliable hybrid cars (8.9 reliability rating).

The most reliable luxury hybrid car is the Lexus ES 300h (8.6 reliability rating), with the Hyundai Ioniq Plug-in Hybrid being the most reliable plug-in hybrid cars (PHEV) (7.2 reliability rating). The Mercedes-Benz S-Class ranks #1 for the most reliable luxury plug-in hybrid cars (PHEV) (7.8 reliability rating).

The most reliable electric car is the Tesla Model S (9.4 reliability rating), which is also the most reliable luxury electric car. The Hyundai Ioniq Electric ranks #1 for the most reliable small and compact electric cars (7.9 reliability rating).

The traditional car lives on, even in an automotive world teaming with SUVs. And for buyers seeking fuel efficient powertrains, a confident and smooth ride, and fun-to-drive dynamics, cars have the natural advantage over their taller, heavier SUV cousins. And, with many automakers now offering all-wheel drive and the added cargo space and utility that comes from hatchback body styles, one could argue today’s cars feature many of the same traits associated with SUVs.

Listed below are the reliability scores for multiple categories, including compact cars, midsize sedans, and luxury sedans. Shoppers looking for reliable vehicles can use these rankings to quickly identify the most reliable sedans, hatchbacks and two-door luxury coupes in a variety of sizes and price ranges.

But reliability is only a single component of a car’s worth. Buyers seeking a low purchase price and high fuel economy should consider the small car categories, with most models powered by turbo four-cylinder engines. Despite their affordable pricing they provide high-tech infotainment systems, featuring high-resolution touchscreens, Apple CarPlay, and Android Auto as standard equipment. Even lower priced models can be found in the used car market, where these dependability rankings are even more important.

Shoppers with a higher budget can consider midsize and full-size new cars, many with more powerful engines, rear-wheel drive, a sporty driving experience, and comprehensive warranty coverage. Their increased weight and higher horsepower mean lower MPG specs, but they also offer increased rear seat room and the latest safety features, particularly in luxury cars. Finally, for consumers who want to completely avoid gasoline, brands like Porsche and Tesla have created electric cars with sports-car personalities. They require a different approach to driving and charging, but it’s not too early to at least learn about these vehicles, as you can expect more EVs in the coming model years.

How We Rank These Cars

The iSeeCars reliability ratings indicate how dependable and long-lasting each vehicle is within its vehicle segment.

Each vehicle is rated on a scale from 1 to 10 with 10 being the highest reliability rating. Vehicles within a given category are sorted to show the most reliable ones first. If two cars have the same ratings, then we break the tie by seeing which vehicle has the higher overall iSeeCars Score. Along with the Reliability ratings, we show comprehensive iSeeCars ratings for each model, because we believe multiple factors should be taken into account when buyers are seeking the best overall vehicle. Two of these factors are safety and resale value, both of which are included in our ratings system.

The overall iSeeCars Score is an analysis of these three factors: reliability, resale value and safety. It is calculated based on the latest research and analysis by our data science team. The data analysis comes from over 12 million new and used vehicles in our Longest-Lasting Cars and 5-Year Depreciation Studies, combined with NHTSA and IIHS Safety Ratings.

Vehicles are scored in three categories:

Reliability | 33.3%

The reliability score represents an analysis of iSeeCars' proprietary research on the longest-lasting vehicles.

Value Retention | 33.3%

The value retention score is based on our data science team's statistical analysis and prediction of 5-year depreciation from MSRP to determine which cars hold their value best, using US Bureau of Labor Statistics data to adjust for inflation.

Safety | 33.3%

The safety score is calculated based on the last five years of crash test ratings from the National Highway Traffic Safety Administration (NHTSA) and incorporates the latest Top Safety Pick information from the Insurance Institute for Highway Safety (IIHS).
