Used Land Rover Defender (2020+): Reliability, Years to Avoid and What to Inspect

Last reviewed: November 2026

The Defender is one of the most popular luxury SUVs we get asked about. It looks like nothing else on the road, it is genuinely capable off-road, and it holds its value well. It also comes from a brand with a mixed reliability reputation, which is why buyers search for years to avoid before anything else. Here is our honest take.

This guide covers the current-generation Defender (internal code L663) sold from 2020 onward, not the classic Defender built until 2016.

The modern Defender lineup at a glance

Engines you will see in the US:

• P300: 2.0L turbo four-cylinder. Lower price, adequate power, less refined.
• P400: 3.0L turbo inline-six with mild hybrid assist. The most popular and, for most buyers, the best balance.
• V8: 5.0L supercharged V8 added later in the model run. Fast and characterful, with higher fuel and running costs.

Year-by-year: what the data says

2020 Defender: the launch year

The 2020 Defender was an all-new vehicle with an all-new electrical architecture and infotainment system. Like most first-year models, it collected more recalls and complaints than later years. Reported issues include engine stalling, cracked windshields, oil leaks and software glitches. Many of these were addressed through recalls and software updates, so a 2020 that has had all its campaigns completed can be a reasonable buy at the right price. Just go in with your eyes open.

2021 Defender: mixed

2021 added the two-door Defender 90. Reliability data is mixed: some sources rate it acceptable, others show above-average complaint levels. Treat it like a 2020: inspect carefully and confirm recall work.

2022 Defender: some electrical complaints

2022 brought the V8 to the lineup. Some sources flag this year for electrical issues, including a DC-DC converter problem, plus windshield and lighting complaints. Again, the fix history of the specific vehicle is what counts.

2023 and newer: the safer bet

Most sources point to 2023 and newer as the best years for a used Defender. By then, many launch issues had been addressed in production. 2023 also introduced the three-row Defender 130. Autotrader, among others, recommends 2023 or newer for buyers shopping used.

Common used Defender problems to check

• Electrical and software glitches. The most common complaint across all years. Test the infotainment screen, cameras, digital gauges, keyless entry, power seats and every light.
• 12V battery drain. Modern Land Rovers are sensitive to battery health. A weak battery can trigger warning lights that look much worse than they are. Ask when the battery was last replaced.
• Windshield cracking. Owners have reported windshield cracks without an obvious impact, especially on early cars. Look closely, including at the edges.
• Oil leaks. Check under the engine and around the top of the engine for seepage.
• Air suspension (if equipped). Raise and lower the vehicle through every height setting and check it sits level after being parked.
• Off-road wear. Some Defenders are actually used off-road. Look underneath for scrapes, bent components and damage to the underbody protection.

If you have read our guide to Range Rover electrical glitches and battery drain, many of the same principles apply to the Defender, since they share a lot of electrical design thinking.

Which Defender should you buy?

• Best overall: a 2023 or newer Defender 110 P400. The inline-six is smooth and strong, and the 110 is the most practical body.
• Best value: a 2021 or 2022 Defender 110 P400 with all recalls completed and a clean history, priced to reflect the extra risk.
• Best for big families: a Defender 130, for genuine adult space in the third row.
• Best for style: the Defender 90. Fewer seats and a smaller cargo area, but it is the most distinctive shape.
• Best for enthusiasts: the V8. Budget for higher fuel, tire and brake costs.

Is a used Defender reliable?

Honestly, the Defender is more reliable than Land Rover's reputation suggests, but it is not a Toyota Land Cruiser. It is a complex, tech-heavy luxury SUV, and the electrical side is where most owners report problems. The engines and drivetrains themselves have generally held up better than the electronics.

Check the factory warranty before you buy

Many used Defenders are still young enough to have some factory warranty coverage left. Coverage length depends on the model year and the original in-service date, so do not assume. Ask an authorized Land Rover retailer to look up the remaining coverage by VIN. If the warranty has ended or is close to ending, read our guide on whether a used car extended warranty is worth it before you decide.

Used Defender pre-purchase checklist

1. Run the VIN for open recalls at nhtsa.gov and ask a Land Rover retailer for completed service campaigns.
2. Review the vehicle history report. Here is how to read a CARFAX report like a dealer.
3. Confirm infotainment software has been kept up to date.
4. Test every electrical feature: screen, cameras, lights, keyless entry, seats, climate.
5. Inspect the windshield edge to edge.
6. Check under the engine for oil leaks.
7. Cycle the air suspension and check ride height after the vehicle sits.
8. Look underneath for off-road damage and Midwest salt corrosion.
9. Ask about the 12V battery age.
10. Get a pre-purchase inspection from a Land Rover-experienced shop. Our Range Rover pre-purchase inspection checklist is a good template.

The Defender in a Chicago winter

The Defender is one of the most capable SUVs you can drive through a Chicago winter. Every US Defender has full-time all-wheel drive, and models with air suspension can raise ride height for deep snow. The two things to watch locally: road salt on the underbody and the 12V battery, which works hardest in cold weather. A rinse after salt storms and a healthy battery go a long way.

Typical Defender repair and running costs

The ranges below are general estimates reported by independent Land Rover specialists and owner communities. Real costs vary by model, region, parts choice and shop. They are not quotes from Autos of Chicago.

Windshield replacement costs more than many owners expect because the forward-facing camera for driver assistance systems must be recalibrated afterward. If you see a crack, check whether your insurance policy covers glass.

Trim levels and options: what to look for

Defenders were sold in a wide range of trims and with a long list of options and accessory packs, so two Defenders of the same year can be priced very differently. A few things are worth paying attention to:

• Air suspension: Not every Defender has it. It improves ride comfort and lets you raise the vehicle for snow and trails, but it adds maintenance cost over time.
• Driver assistance features: Adaptive cruise control and blind spot monitoring were included on some trims and optional on others. Check the build sheet.
• Seating configuration: The 110 was offered with five, six (with a front jump seat) or seven seats. Make sure the layout fits your family.
• Accessory packs: Explorer, Adventure, Country and Urban packs add things like roof racks, side-mounted gear carriers and protection. They add style and utility but are not essential.
• Wheels and tires: Large wheels look great, but smaller wheels with taller all-terrain tires ride better on Chicago potholes and are cheaper to replace.

Ask for the original window sticker or a VIN-based build sheet so you know exactly what the vehicle came with and can compare listings fairly.

Defender vs Range Rover Sport: which should you buy?

Many buyers cross-shop these two. The Defender is more rugged and utilitarian, with a boxy, practical interior and serious off-road credentials. The Range Rover Sport is plusher, quieter and more road-focused, with a more luxurious cabin. If your priority is adventure and a distinctive look, the Defender wins. If you want a luxury SUV that is mostly driven on pavement, the Range Rover Sport is the more refined daily driver. Our Range Rover Sport L494 vs L461 guide covers that side.
