Used Land Rover Defender L663 (2020-2024): Buyer's Guide

In April 2026, NHTSA issued recall 26V248 covering 53,644 Land Rover Defenders from the 2020-2024 model years. The issue: the DC-DC converter in P400 MHEV models can fail, cutting the 12-volt charging system and causing complete loss of drive power while moving. As of June 2026, no dealer remedy was available. Interim owner letters shipped June 12. If you're buying a used Defender with the P400 engine right now, you may be buying a vehicle with an open, unfixable recall on it. That's where this guide starts.

The Defender L663 is one of the most capable vehicles you can buy used. It's also one of the most complex, with documented issues that depend almost entirely on which engine you choose. This guide breaks down what's wrong with each powertrain, which model years to target, and what to check before you hand over the money.

This Generation at a Glance

The L663 launched in the US as a 2020 model year vehicle. It uses Land Rover's Premium Transverse Architecture (PTA), a unibody platform purpose-built for the modern Defender. Three body styles cover different buyer needs: the short-wheelbase 90 (3-door, 5 seats), the standard 110 (5-door, 5 seats, by far the most common), and the extended 130 (5-door, 3-row seating, added to the US lineup for the 2023 model year).

All variants use the same ZF 8-speed automatic and permanent AWD with Land Rover's Terrain Response 2 system. The mid-cycle refresh came in 2023 with Defender 130 availability and revised infotainment software. Browse available Land Rover Defender listings by year to see current inventory and pricing.

Powertrain and Trim Breakdown

P300 (2.0L I4 Turbo): The Clean Option

The P300 is a 2.0L turbocharged four-cylinder making 296 horsepower and 295 lb-ft of torque. It powers the entry-level S and SE trims across both the 90 and 110 body styles. No mild-hybrid system. No DC-DC converter. No exposure to recall 26V248.

The P300 is the most reliable powertrain in the L663 lineup. The ZF 8-speed gearbox it pairs with is a known-robust unit shared across dozens of premium platforms. Owners report no mechanical failure patterns unique to the P300 engine itself. On-road, you give up about 100 horsepower versus the P400, but in real-world Defender usage, the P300 is sufficient for everything including towing up to 8,200 lbs.

Fuel economy is 18-19 mpg combined in the 110 body style. Not impressive for a modern vehicle, but typical for the segment.

First-year 2020 P300 models carry the worst Pivi Pro infotainment software. The infotainment froze, switched audio sources on its own, and displayed incorrect time readings regularly on 2020-2021 examples. Software updates issued through 2022 addressed most of these faults, but used 2020-2021 vehicles may not have received all updates. A dealer service visit to confirm current firmware is worth the trip before purchase.

What owners say: The P300 gets less attention in Defender forums than the P400, which owners take as a good sign. The absence of complaints about engine-specific issues is itself a data point.

P400 (3.0L I6 MHEV): More Power, One Big Problem

The P400 is a 3.0L turbocharged inline-six with a 48-volt mild hybrid system. It produces 395 horsepower and 406 lb-ft of torque. The mild hybrid uses a Belt-Integrated Starter Generator (BISG) and a 48V lithium battery to harvest braking energy and provide electric torque fill under acceleration. It is the most popular Defender powertrain on the used market.

Recall 26V248 covers this engine specifically. The DC-DC converter converts 48-volt MHEV power to 12-volt system power for charging and accessories. When the converter's boost control microchip develops an internal fault, it cuts 12-volt charging. The vehicle continues running for a short time before the 12-volt battery depletes, at which point drive power, exterior lighting, and controls shut down. A driver will see a "Stop Safely Electrical Fault Detected" warning before the shutdown. JLR received nearly 6,000 DC-DC converter warranty claims in the US between July 2019 and April 2026 before issuing the recall. The recall covers 53,644 Defenders in the 2020-2024 range. No dealer remedy was available when this guide was written.

Before buying any P400 Defender, run the VIN on NHTSA.gov or use CarScout's recall lookup. If recall 26V248 shows open, the recall has not been completed. You are buying a vehicle that may lose drive power until Land Rover releases and deploys a fix.

P400 MHEV faults extend beyond the recall. Early 2020-2021 models logged frequent BISG fault codes that dropped the MHEV system into a reduced-function mode. These triggered warning lights and occasional rough running. Software updates addressed many of these faults for 2022 and later production. Pre-purchase OBD scan on any P400 under 60,000 miles is worth doing to check for stored MHEV fault codes.

The P400 is otherwise an excellent engine. The six-cylinder is smooth, quiet at highway speed, and the torque fill from the MHEV makes the Defender feel lighter than it is. If the DC-DC recall is resolved on a specific example, the P400 is a strong long-term powertrain.

P400e (PHEV): Battery Complexity Added

The P400e plug-in hybrid arrived in the US for 2022, available only on the Defender 110. It combines the 3.0L inline-six with an electric motor for a combined 398 horsepower and 472 lb-ft of torque. The P400e uses a different high-voltage architecture than the 48V MHEV system. It is not affected by recall 26V248.

The P400e has its own issues. The transition from electric to petrol power is rougher than the six-cylinder-only P400 at low speeds, particularly when creeping in stop-and-go traffic. Gas particulate filter (GPF) warning lights appear when the vehicle primarily runs on battery in city driving because the petrol engine never gets hot enough for GPF regeneration. Some dealers have noted incomplete fix options for this. One commonly reported failure involves complete infotainment and ADAS black screens during driving, which required a 20-minute power cycle to reset.

Electric-only range is approximately 19 miles on a full charge. Beyond that, you're running the four-cylinder petrol section of the powertrain. EPA combined in gas-only mode is around 31 mpg. If your commute is longer than 19 miles and you charge overnight, fuel costs drop significantly. If you primarily highway drive, the hybrid premium buys you little benefit.

High-voltage battery degradation becomes a factor after 50,000-60,000 miles. Replacement costs for the traction battery are not yet well-documented given the relative youth of these models, but expect a significant repair bill.

P525 V8 (5.0L Supercharged): The Enthusiast Tax

The 5.0L supercharged V8 producing 518 horsepower launched in the Defender 110 for 2021 and ran through 2022 in variants including the Carpathian Edition. It was not offered in the Defender 90 in the US. It is not affected by the MHEV recall.

The V8's primary maintenance concern is the timing chain. The JLR 5.0L V8 engine requires oil changes at 7,500-mile intervals or less. Running this engine on extended 10,000-15,000 mile change intervals causes timing chain stretch and VVT system wear. Request the full oil change history on any V8 example. Listen at a cold start for a faint ticking that does not fade at operating temperature, which is the early sign of chain wear on this engine.

V8 Defenders have depreciated considerably. Examples that listed at $90,000-$110,000 new are now in the $55,000-$80,000 range used. That makes the V8 more accessible, but at 15-16 mpg combined, annual fuel cost at 15,000 miles runs roughly $3,000 at current prices. Factor that against the P400's 19 mpg before deciding whether 100+ extra horsepower is worth the ongoing cost.

Trim-Specific Notes

The L663 trim structure evolved over model years but generally spans: S (entry), SE, SE X-Dynamic, HSE, X-Dynamic HSE, and X (top). First Edition models from 2020-2021 are launch-year specials with the P400 engine, but carry no feature advantage over later production HSE or X trims.

Air suspension is standard on the X trim and optional on HSE. It provides genuine ride quality improvement and enables height adjustments for off-road modes. The tradeoff: Land Rover identified a batch of faulty front air springs on Defenders manufactured between August 1 and November 20, 2020, covered under service message SSM 75281. Outside that batch, air suspension failure typically appears in the 60,000-80,000 mile range. Air spring replacement runs $1,471-$1,528 per corner. Air compressor replacement adds $1,870-$1,927. After-ride height calibration with JLR diagnostic tools is mandatory after any air spring replacement.

If a front air spring fails on a 2020-2022 model, assume the other front spring is close behind. Replace in pairs.

An SE or HSE Defender without optional air suspension costs less at purchase and sidesteps the air spring failure chain entirely. For most buyers, the coil-spring versions are the right call unless you specifically need the height adjustment for serious off-road use.

The Defender 130 (three-row) was added to the US lineup for 2023. It is only available with the P400 and P400e powertrains, which means every Defender 130 carries the MHEV recall exposure. There is no P300 option for buyers who want the third row.

Which Model Years to Target Within This Generation

2020-2021: The launch years have the most documented issues. Pivi Pro version 1 was bad enough that Land Rover eventually released major OTA updates, but used examples may not have all updates applied. These years also have the highest rate of water ingress reports. First-year buyers absorb the development costs.

2022: The P400e joined this year, adding PHEV complexity to the lineup. The oil filter housing recall (incorrect plastic specification cracking under pressure) affects some 2022-2024 builds. Check VIN recall status before purchase.

2023: The most available used inventory with 755 US listings as of June 2026. Software was meaningfully more stable by this year. The camera recall (N972) covers a 2023-2024 software bug causing a blank rearview image when shifting to reverse. It's a simple reflash. The 2023 P300 SE or HSE without air suspension is the clearest used buy in this generation.

2024: Carries DC-DC recall exposure on P400 models. Further software refinements compared to 2022-2023. Prices will be higher than 2022-2023 examples.

Pre-Purchase Inspection Checklist

All Powertrains

Lift both front floor mats completely before doing anything else. Look under the driver's seat for the ECU module box. Any dampness, salt residue, or white mineral deposits on the module means water has reached the electronics. Water enters through degraded A-pillar grommets or blocked panoramic roof drains and pools silently. ECU corrosion repair runs $2,000-$3,000 at minimum. Walk away from any car with wet electronics unless the price reflects a significant discount plus repair cost.

Run the VIN through CarScout's recall lookup and verify all open recalls before you go further.

Start the car cold. Watch the Pivi Pro boot completely before driving. On a 2020-2021, the system should load within 90 seconds without partial screens or frozen icons. Force a reboot by pressing and holding the power button 10 seconds. Two or more cycles to come back cleanly means the software is not current.

Inspect the windshield for cracks originating from the edges with no obvious impact point. Spontaneous edge cracking is a documented widespread issue affecting 2020-2024 Defenders. A class-action lawsuit was filed in 2024. JLR has not issued a recall. OEM heated windshield replacement: $2,100 or more. An edge crack means replacement is near-term.

Open the cargo floor and examine the rear shock shaft wiring at the upper mount. If the wires appear twisted tightly around each other, the shock is rotating in its mount. Those wires will eventually snap.

P400 MHEV Specific

Check NHTSA.gov for recall 26V248 by VIN. If it shows open, use it to negotiate, but understand the remedy timeline is unknown as of this writing. Request a pre-purchase OBD scan and ask specifically about stored MHEV or BISG fault codes. Frequent codes under 50,000 miles suggest accelerated 48V battery wear.

Air Suspension Models (X Trim or Optional Air Suspension on HSE)

Park on level ground and shut the engine off. Return after 30 minutes. If any corner has visibly dropped compared to the others, a slow air spring leak is underway. Start the engine and watch all four corners level up. Slow leveling means the compressor is working harder than normal to compensate, which accelerates compressor wear.

Confirm whether the vehicle falls within the August 1 to November 20, 2020 build date range covered by SSM 75281. Ask the dealer to verify this was addressed in service records.

V8 Models (P525)

Ask for oil change records and count intervals. Any gap longer than 7,500 miles is a flag. Cold-start the engine and listen for a tick that follows RPM for more than two to three minutes. Timing chain rattle that does not fade at normal operating temperature on the 5.0L V8 means significant chain wear. Cost to address: $4,000-$6,000 at a JLR specialist.

Running Costs

All L663 models use Castrol Edge 0W-20 full synthetic. Dealer oil change service runs $200-$300. Independent JLR specialists typically charge $150-$200.

Edmunds projects $8,400 in total repairs and maintenance over 5 years for the 2020 Defender, roughly $1,680 per year. That baseline does not include unscheduled repairs. Windshield replacements ($2,100+ OEM) and air suspension failures ($1,500-$4,000 per repair event) are common and will add to that number on early models.

Extended warranty coverage is worth serious consideration given the electronic complexity and the ongoing MHEV recall. Land Rover's factory warranty is 3 years. Most 2020-2021 examples are outside coverage.

Frequently Asked Questions

Is the Land Rover Defender L663 reliable? It depends on the powertrain. The P300 (non-MHEV) has no significant documented failure patterns. The P400 MHEV carries recall 26V248 for DC-DC converter failure with loss of drive risk, and a remedy was not available as of June 2026. Early 2020-2021 models of any engine had Pivi Pro bugs and water ingress ECU problems at higher rates than later production.

What year Land Rover Defender should I avoid? The 2020 and 2021 model years have the most documented issues: worst Pivi Pro software, highest water ingress complaint rates, and the 2020 air spring batch issue from August-November production. If you buy a 2020-2021, price in a full JLR software update visit and a water ingress inspection by a specialist.

What is the difference between the P300 and P400 Defender? The P300 is a 2.0L four-cylinder (296hp) with no hybrid assist. The P400 is a 3.0L six-cylinder (395hp) with a 48-volt mild hybrid system. The P400 is more powerful and smoother at highway speeds. It is also the only engine affected by recall 26V248, which can cause complete loss of drive power while moving. For buyers prioritizing long-term reliability on a used purchase, the P300 carries less current risk.

Does the Defender L663 have air suspension? Air suspension is standard on the X trim and optional on HSE. It improves ride quality and enables height changes for off-road modes. The tradeoff is failure risk: air spring replacement costs $1,471-$1,528 per corner, and compressor replacement adds $1,870-$1,927. A batch of 2020 production vehicles (August-November 2020) had faulty front springs covered under SSM 75281. Coil-spring SE and HSE trims skip this failure mode entirely.

How long does a Land Rover Defender L663 last? The L663 is too recent for long-term mileage data. The PTA platform and ZF 8-speed gearbox are fundamentally capable of high mileage. The main threats to longevity are unaddressed recalls, water ingress that corrodes ECUs, and MHEV system wear on the P400. A well-maintained 2022-2023 P300 without water damage and current firmware has no known early failure modes. Expect 150,000+ miles with proper maintenance.

Bottom Line

The 2023 P300 Defender 110 SE or HSE without air suspension is the clearest buy in this generation: no MHEV recall exposure, improved Pivi Pro software, solid used inventory (755 listings in the US as of mid-2026), and no air suspension failure chain to manage. If the P400 is what you want for the performance, run the VIN through a recall check and confirm recall 26V248 status before signing. An open recall on the DC-DC converter is a negotiating chip, but you need to know what you're buying.
