Known problems
- Critical
DC-DC converter failure on mild-hybrid models (US recalls 26V248000 / 26V599000)
Symptoms: loss of 12-volt charging, warning messages, exterior lights going out and a complete loss of drive power while driving
What to do: Land Rover recalled certain mild-hybrid (MHEV) Defender 2020-2024 models because the DC-DC converter can be overloaded under high electrical demand; a failure can cause a complete loss of drive power. Check the VIN on nhtsa.gov (or with a Land Rover dealer outside the US) for open recalls and have the remedy done.
- Critical
Driver airbag clockspring corrosion (US recall 26V389000)
Symptoms: airbag warning light, horn or steering-wheel control faults; the driver airbag may not deploy as intended
What to do: The recall covers certain 2020-2026 Defender vehicles where the driver's airbag clockspring connector can corrode. If the airbag light is on, or the car has an open recall, do not delay the dealer repair.
- Critical
Engine oil leak fire-risk recalls (US recalls 23V044000 / 24V450000)
Symptoms: oil smell or smoke, visible leaks at the top of the engine or the oil filter housing, a falling oil level
What to do: Two NHTSA recalls cover oil leaks that can reach hot components: a blocked cam carrier oil channel (2020-2023 Defender, among other models) and a cracking oil filter housing (2023-2024 Defender). Check the VIN for completed remedies and do not ignore oil leaks or oil-level warnings on these cars.
- Critical
Powertrain control module can switch off (US recall 21V424000)
Symptoms: sudden engine stall while driving with no warning on 2020-2021 six-cylinder cars
What to do: Certain 2020-2021 Defenders with six-cylinder engines were recalled because the PCM can switch off in motion, causing an engine stall. Confirm with a dealer that the software remedy has been done on any 2020-2021 car.
- Worth watching
Touchscreen blank at start-up and rear-camera image missing (US recall 25V016000)
Symptoms: central screen goes blank when the car starts, no rear-view camera image when reversing
What to do: Certain 2023-2024 Defender vehicles were recalled because the infotainment touchscreen can blank at start-up and not show the rear camera. Check the VIN for the software remedy, and do not rely on parking sensors alone until it is done.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Air suspension & ride height check | every 15,000 mi (24,000 km) or 12 months | air suspension is standard on most trims; check the compressor, hoses, bags and ride-height sensors for leaks and slow sagging at each service |
| DPF / AdBlue (diesel) | every 15,000 mi (24,000 km) or 12 months | diesels use AdBlue and a DPF; keep the AdBlue topped up and give the DPF regular longer runs to regenerate |
| Engine oil & filter change Important | every 15,000 mi (24,000 km) or 12 months | the factory interval is longer than the real-world advice for diesels and short-trip cars; many owners and specialists change it at 12-15,000 km, especially after the oil-leak recall work. Use the exact JLR-approved low-SAPS specification |
| Air filter & cabin filter | every 37,000 mi (60,000 km) or 48 months | shorten in dusty or off-road use; interval depends on market and engine, so check your service booklet |
| Automatic gearbox & transfer case oil Important | every 62,000 mi (100,000 km) | the 8-speed automatic and transfer case are filled with a long-life oil that is often described as 'lifetime'; independent specialists suggest renewal around 100,000 km, sooner for towing or off-road use |
| Spark plugs (petrol) | every 62,000 mi (100,000 km) | petrol engines only; the interval varies by engine and market |
| Brake fluid Important | every 36 months | check your service booklet; 2-3 years is the usual window |
| Coolant | every 72 months | extended-life coolant; renew by the service booklet or on suspicion of leaks, and have the cooling circuit pressure-tested at major services |
| Software updates & recall check Important | every 12 months | check for open recalls and the latest software with the dealer at each service; several safety recalls (see known issues) are fixed by reprogramming |
Classic 90/110 (1983-2016) · 1983–2016
2.2 TDCi Puma diesel (2012-2016) · 122 hp · 2.4 TDCi Puma diesel (2007-2011) · 122 hp · 2.5 200Tdi diesel (1990-1994) · 107 hp · 2.5 300Tdi diesel (1994-1998, 111-113 PS) · 111 hp · 2.5 Td5 diesel (1998-2007) · 122 hp · 3.5 V8 petrol (carburettor, early cars)
Known problems
- Critical
Sump oil pick-up pipe (2.4 Puma, early cars)
Symptoms: low oil pressure warning, sudden loss of oil pressure or a failed engine on an early 2.4 TDCi car
What to do: Early 2.4 TDCi Defenders had a push-fit sump oil pick-up pipe that was the subject of a Land Rover service action. Ask a Land Rover dealer or specialist, with the VIN, whether the correct pipe has been fitted; if there is no proof, treat it as a priority job.
- Critical usually from 60,000 mi (96,000 km)
Tdi timing belt failure (200Tdi / 300Tdi)
Symptoms: no warning in most cases; squealing or ticking from the front cover, then a sudden stop and a non-starting engine if the belt breaks
What to do: A broken belt can cause major internal engine damage. If there is no proof of a belt change in the last 5 years or about 96,000 km, replace the belt, tensioner and water pump immediately. Use quality parts and check the front cover and backplate while it is apart.
- Worth watching
Chassis, bulkhead and door-frame corrosion
Symptoms: flaking or holed metal at the rear cross member and outriggers, rotten bulkhead footwell and A-post areas, bubbling at door frames where steel meets the aluminium panels, creaks and sagging doors
What to do: Structural rust is the main thing that decides the value of an old Defender. Before buying, inspect the chassis end to end with the car on a lift, tap the bulkhead and outriggers, and check the door frames. Budget for professional repair or a galvanised replacement chassis; do not rely on underseal over rust.
- Worth watching
DPF clogging on short-trip use (2.2 TDCi, 2012-2016)
Symptoms: DPF warning light, limp mode, repeated regeneration attempts, an increase in fuel consumption or oil level
What to do: Euro 5 2.2 cars have a DPF that needs sustained driving at speed to regenerate. If the Defender mostly does short trips, plan regular longer drives, use low-ash oil and check the oil level, since failed regenerations can dilute the engine oil. A blocked DPF may need professional cleaning or replacement.
- Worth watching
MT82 gearbox output shaft spline wear (2.4 / 2.2 Puma)
Symptoms: loss of drive or drive intermittently disappearing, clunking and vibration from the gearbox, noise when pulling away
What to do: On the MT82 6-speed manual, the gearbox output shaft splines can wear due to marginal lubrication. Check for play at the shaft and companion flange when buying, and check the oil level and condition at every service. Early repair is much cheaper than a failed gearbox.
- Worth watching
Td5 injector wiring harness oil contamination
Symptoms: rough running, misfires, hesitation, intermittent limp mode or flat spots; oil found inside the engine loom connector or the ECU
What to do: On Td5 engines, engine oil can wick along the injector harness into the connector or the ECU. Have the loom and connectors checked at service, replace the loom if oil is present, and clean or replace the ECU connector if it is contaminated. Keep an eye on this when buying any Td5 (1998-2007).
- Worth watching usually from 81,000 mi (130,000 km)
Puma injectors, EGR cooler and turbo actuator faults
Symptoms: rough idle, black smoke, loss of power, hard starting, coolant loss or white smoke from the EGR cooler, limp mode from a failed turbo actuator
What to do: Common-rail injectors last longest on clean fuel and with a fresh fuel filter; contaminated diesel is the usual killer. Pressure-test the cooling system and look for EGR cooler leaks, and use a diagnostic tool to check the turbo actuator before buying. Choose a specialist for injector replacement and coding.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | Tdi engines are happiest at 5,000-8,000 km (specialist advice) and the 200/300Tdi turbo is oil-fed, so do not stretch it. Td5 and Puma are officially on longer intervals (the Puma up to about 19,000 km / 12 months), but 10,000 km is the safer real-world figure, especially for short trips |
| Swivel housing oil & grease points Important | every 6,000 mi (10,000 km) or 12 months | top up swivel housings and grease the propshafts, steering joints and hinges at each oil service; neglected swivel seals leak and wear the ball joints |
| Fuel filter & water separator drain (diesel) Important | every 12,000 mi (20,000 km) or 12 months | drain the water trap more often if the vehicle sits or runs on poor fuel; contaminated fuel is the common killer of Td5 and Puma injectors |
| Air filter | every 19,000 mi (30,000 km) | check the restriction indicator on Tdi/Td5 and shorten the interval in dusty or off-road use |
| DPF / EGR check (2.2 TDCi, 2012-2016) | every 19,000 mi (30,000 km) | Euro 5 2.2 cars have a DPF; make regular longer motorway runs so it can regenerate, and watch for EGR-related smoke or limp mode |
| Gearbox, transfer box & differential oils Important | every 37,000 mi (60,000 km) or 48 months | check levels at every service; manual gearboxes (LT77/R380) and the transfer box (LT230) share a long-life gear oil but benefit from renewal. The later MT82 6-speed on the 2.4/2.2 cars is filled at the factory with no widely quoted interval, so ask a specialist |
| Timing belt, tensioner & water pump (200Tdi / 300Tdi) critical | every 60,000 mi (96,000 km) or 60 months | belt-driven engines; the factory distance is roughly 60,000 miles, many specialists shorten it to about 5 years regardless of mileage. Td5 and Puma 2.4/2.2 are chain-driven with no scheduled replacement, but a rattle on cold start means the chain tensioners or guides need attention |
| Brake fluid Important | every 24 months | — |
| Coolant | every 48 months | use the correct long-life antifreeze mix; check the hoses and the radiator for age |

Lab-cycle figures, each shown with the cycle it was measured under — the same car under EPA, WLTP, NEDC or JC08 can differ by up to 20%. Real driving always falls short of the declared figure: roughly 10–20% on an EPA rating, 15–30% on a WLTP or NEDC one. That gap is normal, not a fault.
