Buying a used SUV is a great way to avoid the steep depreciation of a new model, but you will only realize meaningful savings if you buy something reliable. Otherwise, you may be faced with unexpected repairs, or high service charges that can quickly erode the money you saved on buying used.
To reduce the likelihood of that happening, we picked five of the most reliable used SUVs according to the J.D. Power Vehicle Dependability study. We focused solely on 2021 model year SUVs, which should still be modern enough to offer the tech and comfort you expect in a daily driver, but at a big cost saving.
The J.D. Power study referenced here analyzed 2021 model-year vehicles after three years of ownership, measuring Problems per 100 vehicles (PP100) across nine categories—from powertrain to infotainment. While the industry average for 2021 models dipped due to software complexities, and supply-chain issues, these five SUVs maintained the highest reliability scores in their respective segments by utilizing tried-and-trusted mechanical platforms and proven interior tech.

All vehicle data was sourced from the respective manufacturers and new pricing excludes destination charges and taxes which can often add $2,000 to the base MSRP. Used pricing data was sourced from AutoTempest and represents the average figure for all trim types of that particular model sold over the past year.
1. Chevrolet Equinox (Compact SUV)
Mueller/Chevrolet
- Reliability Score: 88/100
- Average Used Price (2021 Model): $16,950 est.
- 2026 Base MSRP: $28,800 excl taxes
The Equinox secured the highest reliability rating on this list, and for the 2021 model year, the LT trim with the 1.5L turbocharged engine is the most reliable choice, as it avoids the high-feature density and electronic issues found in the Premier trim. To ensure the best reliability, avoid models with the panoramic sunroof, which owners reported as a source of leaks and motor noise. Sticking with the Front-Wheel Drive (FWD) version also eliminates the maintenance and potential failure points of the All-Wheel Drive transfer case.
The 2021 model is part of the previous generation Equinox which was sold between 2018 and 2024. The 2026 model features a new 8-speed automatic and a massive 11.3-inch screen; while modern, new generations typically see a spike in “teething” software glitches that the 2021 model has already moved past.
2. Toyota 4Runner (Midsize SUV)
Toyota
- Reliability Score: 86/100
- Average Used Price (2021 Model): $36,356 est.
- 2026 Base MSRP: $41,870 excl taxes
The 4Runner remains a reliability titan because it uses a long-standing engine and transmission design that has virtually no “teething” issues. The SR5 or Limited trims are the most straightforward for long-term ownership. To get the best reliability, avoid the TRD Pro unless you are a dedicated off-roader; the specialized Fox shocks on the Pro are high-maintenance and expensive to rebuild compared to the standard suspension on the SR5. Most “problems” reported for this vehicle are actually about its dated infotainment system, rather than any mechanical failure.
The 2021 model is widely considered “bulletproof” because it uses an ancient, low-stress V6 engine and a 5-speed transmission. The newer model switches to a high-output 2.4L turbocharged 4-cylinder and an 8-speed transmission. While more efficient, the 2021 model’s “dinosaur” tech has a proven 200,000-mile track record that the new turbo engines have yet to match. The 4Runner has also retained a big chunk of its value thanks to that old-school reliability.
3. Lexus RX (Midsize Premium SUV)

- Reliability Score: 85/100
- Average Used Price (2021 Model): $35,671 est.
- 2026 Base MSRP: $51,975 excl taxes
The Lexus RX is the segment winner for Midsize Premium SUVs. The RX 350 trim with the 3.5L V6 is known for solid and durable performance, offering a more predictable lifespan than the hybrid models. To maintain peak reliability, avoid the “L” (extended) version, as the power-folding third-row seat motors are one of the few noted failure points in owner surveys. Also, stick to the 18-inch wheels if possible; the 20-inch wheels on higher trims are more prone to tire wear and vibration complaints.
The current generation RX was introduced in 2023 and has moved to 4-cylinder hybrid and turbo power. Time will tell whether these engines will be regarded as highly in the reliability stakes as the old-tech V6. The new models also feature a complex “Lexus Interface” touchscreen that replaces the 2021 model’s physical buttons; historically, these new software interfaces are a major source of owner complaints in the first few years.
4. Buick Enclave (Upper Midsize SUV)
- Reliability Score: 83/100
- Average Used Price (2021 Model): $24,457 est.
- 2026 Base MSRP: $46,400 excl taxes
The Enclave shares its architecture with the Chevrolet Traverse, benefiting from a platform that GM had ironed most wrinkles out of by 2021. The Essence trim is the most reliable path, providing a luxury feel without the Avenir’s complex adaptive suspension and massaging seats, which are common sources of electronic sensor errors. To ensure the best results, avoid models used for heavy towing unless they have a verified service history, as the 9-speed transmission is the most sensitive mechanical component in this vehicle.
The 2021 Enclave uses a 3.6L V6 that was in production for over a decade and should deliver above average reliability when regularly serviced. The new model replaces this with a 2.5L turbocharged engine and a massive 30-inch curved glass display. While the turbo motor offers better economy and power, and the huge new display is very impressive, we will have to wait a few years before knowing just how reliable this newer tech is.
5. Chevrolet Tahoe (Large SUV)
Chevrolet
- Reliability Score: 82/100
- Average Used Price (2021 Model): $41,904 est.
- 2026 Base MSRP: $60,700 excl taxes
The Tahoe led the large SUV segment in this study, proving that even a full redesign in 2021 didn’t compromise its dependability. The LS or LT trims with the 5.3L V8 engine are the most reliable configurations, as the 5.3L has fewer reported valve-train issues than the more powerful 6.2L V8. To get the best reliability, avoid the High Country or Z71 trims with “Air Ride Adaptive Suspension.” These air-based systems are far more likely to fail after the five-year mark compared to the traditional coil springs found on the lower trims. Since the 2021 and 2026 models share the same 5.3L V8 engine, the core mechanical reliability remains similar.
However, the latest update introduces “Super Cruise” hands-free driving and a much larger 17.7-inch screen. The simpler electronics in the 2021 model may not have all the functionality of the 2026 models, but they may have the edge in terms of reliability purely due to the fact that GM has had more time to refine these systems.
