As consumers continue to prioritize reliability when purchasing vehicles, understanding which car brands stand out in terms of long-term dependability is essential. In 2025, Buick has emerged as the most reliable American car brand, leading the pack in the J.D. Power PP100 survey, with top models like the Envision and Encore GX showcasing impressive reliability. But what exactly makes a brand reliable, and how do U.S. carmakers compare to their Japanese and Korean counterparts? This data-driven comparison delves into how reliability is measured in the automotive industry, explains the significance of J.D. Power’s PP100 metric, and highlights the standout features of Buick and other U.S. brands.
What is the Most Reliable American Car Brand in 2025?
In 2025, Buick is considered the most reliable American car brand. According to J.D. Power’s PP100 data, Buick outperforms other U.S. automakers with a relatively low PP100 score, making it the most dependable option for buyers in the domestic market. Its top models, such as the Buick Envision and Buick Encore GX, consistently score well, with owners reporting fewer issues compared to other American-made vehicles. Buick’s reliability stands out as a key factor in its ongoing success in the competitive automotive market.
How is “Reliability” Measured in the Automotive Industry?
Reliability in the automotive industry refers to the frequency, severity, and cost of repairs a vehicle experiences over time. It is typically measured using owner surveys that gather feedback on issues experienced within the first 12 to 36 months of ownership. One of the most widely recognized metrics for this measurement is J.D. Power’s PP100 (Problems Per 100 Vehicles) scale. A lower PP100 score indicates that fewer problems are reported, suggesting a more reliable vehicle. This data helps both manufacturers and consumers assess a car’s dependability and predict potential repair costs.
What is J.D. Power’s Pp100 Metric and Why Does It Matter?
The PP100 metric, developed by J.D. Power, is a standard tool used to measure the reliability of vehicles based on real-world owner experiences. It surveys thousands of car owners to track problems that occur within the first 12–36 months of ownership, with the results expressed as the number of issues reported per 100 vehicles. A score of 143 PP100, for example, means that for every 100 vehicles, 143 problems were reported. This metric is important because it provides consumers with a clear, data-backed benchmark that helps them assess the quality, durability, and expected repair costs of different car models, enabling more informed purchasing decisions.
How Do U.S. Brands Compare to Japanese and Korean Automakers?
When comparing U.S. brands to foreign automakers, Japanese and South Korean carmakers generally outperform American brands in terms of reliability. For instance, Toyota and Honda, two of the most prominent Japanese brands, often score in the range of 100–110 PP100, reflecting strong reliability. Hyundai and Kia, representing South Korea, have also earned a reputation for producing highly reliable vehicles, with PP100 scores typically between 80–100. While Buick’s 143 PP100 is the best among U.S. automakers, it still lags behind these top foreign brands, highlighting the challenges American manufacturers face in closing the reliability gap with their overseas competitors.
Why is Buick Considered the Most Reliable American Car Brand?
Buick has earned its spot as the most reliable American car brand due to a combination of solid engineering, a focus on simplicity in design, and rigorous quality control processes. The brand avoids the introduction of overly complex, high-tech features that often lead to problems in other vehicles. Buick also emphasizes incremental improvements to its models rather than radical changes, which helps maintain consistency and reduces the likelihood of issues. This stability is crucial in minimizing repeat repairs and maximizing long-term owner satisfaction, making Buick a trusted choice for buyers looking for dependable vehicles.
What Features Make Buick Stand Out in Dependability?
Several features set Buick apart when it comes to dependability:
- Strong Quality Control: Buick’s rigorous manufacturing process ensures that each vehicle meets high-quality standards, leading to fewer defects and long-term dependability.

Cadillac earns a respectable 169 PP100—the best among U.S. luxury brands.
- Cadillac CT5: few engine or infotainment problems; strong chassis and build integrity.
- Cadillac XT6: owners appreciate minimal electronic issues and high resale value.
How Do GMC and Chevrolet Perform in Dependability Studies?
GMC ranks above average for U.S. trucks and SUVs.
- Sierra: strong motor reliability and transmission durability.
- Yukon: reliable powertrain and cabin systems.
Chevrolet mirrors GMC’s performance. - Silverado/Tahoe: generally dependable but occasional electronics or body-related repairs increase average PP100 to mid-tier.
Why Do Ford and Jeep Lag Behind in Reliability?
Ford and Jeep face more frequent repairs thanks to complex electronics, multiple powertrain variants, and off-road focus.
- Ford F‑150, Explorer: owners report transmission problems and modern infotainment bugs.
- Jeep Wrangler, Grand Cherokee: high off‑road durability conflicts with everyday reliability; more suspension and body electronics issues.
What Should Car Buyers Consider Beyond Reliability?
While reliability is critical, buyers should also take other factors into account when making a car purchase:
- Safety: Look for high safety ratings and features like airbags, collision warning systems, and crash-test results.
- Fuel Efficiency: Consider the vehicle’s gas mileage, especially for long-term cost savings.
- Resale Value: Some brands hold their value better than others, which is important if you plan to sell or trade in your vehicle later.
- Warranty: A comprehensive warranty can offer peace of mind and help protect against unexpected repair costs.
- Technology & Features: Evaluate the tech features that matter most to you, such as infotainment systems, driver-assistance technologies, and connectivity options.
How Do Safety, Resale Value, and Maintenance Cost Compare?
| Brand | Reliability | Safety Ratings | Resale Value | Avg. Maintenance Cost |
| Buick | Highest U.S. | 4–5★ IIHS/NHTSA | Strong (luxury) | Moderate |
| Cadillac | Good | 4–5★ | High (premium) | Higher (luxury level) |
| GMC | Above Avg. | 4–5★ | Very High | Moderate–High |
| Chevrolet | Mid‑tier | 4★ | Good | Mod–High |
| Ford | Below Avg. | 3–4★ | Moderate | Moderate |

- Cadillac focuses on premium infotainment and driver assist features with moderate MPG expectations.
- GMC/Chevrolet prioritize utility and towing over plush interiors.
- Ford and Jeep emphasize performance and ruggedness but lag in comfort and mileage.
How Does Vehicle Type Affect Reliability Scores?
Vehicle type plays a significant role in determining reliability scores, as different types of vehicles have varying levels of complexity, usage patterns, and durability. Sedans, typically simple in design, tend to have higher reliability scores due to fewer moving parts and less wear and tear. On the other hand, SUVs and trucks, which are often subjected to more strenuous use such as off-roading or towing, may experience more mechanical stress, leading to lower reliability scores over time. Luxury vehicles, while offering advanced technology and comfort, can sometimes have lower reliability due to their complex systems and higher repair costs. Similarly, sports cars designed for performance may face higher maintenance needs, further affecting reliability. Electric vehicles, with fewer moving parts and no traditional engine, often score higher in reliability, though battery and electrical system longevity can still be a concern. Ultimately, vehicle type influences reliability based on factors like design, usage, and technological complexity.
Are Sedans More Reliable Than Trucks or SUVs?
Sedans trend more reliable because of fewer payload/towing demands and simpler structures. Buick Envision (SUV) bucks that trend with low defect rates. Heavy trucks/SUVs often face more drivetrain and suspension issues.
How Do Electric Vehicles From U.S. Brands Perform?
U.S. electric models like Tesla, Rivian, GM Hummer EV, and Ford Mustang Mach-E show mixed reliability—battery at manufacturing is strong, but electronics and software glitches still linger. Cadillac and Buick have so far avoided mainstream EV lineups.
