EXTERIOR LIGHTING:TAIL LIGHTS
Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2020-2022 Defender X vehicles equipped with smoked rear light assemblies. A voltage spike, triggered by a bright light shining on the rear of the vehicle, can cause the turn signals, brake lights, and tail lights to fail.
SEAT BELTS:PRETENSIONER
Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2022-23 Land Rover Defender, Discovery, Discovery Sport and 2022 Range Rover Sport and Range Rover Velar vehicles. The driver and front passenger seat belt pretensioners may be damaged, which can cause the seat belts to not properly restrain occupants.
AIR BAGS:FRONTAL
Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2020-2026 Land Rover Defender, 2021-2026 Discovery, and 2022-2026 Range Rover vehicles. The driver’s air bag clockspring connector may corrode, which can cause the air bag not to deploy as intended.
BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2024 Defender, Discovery Sport, Range Rover, Range Rover Evoque, Range Rover Velar, and Range Rover Sport vehicles. The Near Field Sensing Module (NFSM) may overheat and cause the 3D surround camera images, including the rearview camera image, not to display.
EQUIPMENT
Jaguar Land Rover North America, LLC (Land Rover) is recalling certain 2020-2025 Land Rover Defender vehicles equipped with Raised Air Intake (RAI) aftermarket accessory equipment, with part number VPLEP0543.

Our known issues database covers the 1983-2025 Land Rover Defender with 44 documented issues documented across 1,370+ owner reports.
Despite the era's reputation, the Td5 chassis is NOT galvanised from the factory and rots in the classic mud/water traps: the boxed rear crossmember, the rear spring hangers (corrosion often hidden until the coils are removed), and the chassis rails where the gearbox crossmember… Repairs typically run $400-$4,500. Severity: high.
The 300Tdi-era Defender's pressed-steel bulkhead (firewall) is the single most expensive corrosion point on the vehicle. Water drains down the windscreen and collects in the lower box sections behind the footwells, around the A-post feet where the bulkhead bolts to the chassis ou… Repairs typically run $800-$4,500. Severity: high.
The 300Tdi Defender's ladder chassis is mild steel, not galvanised from the factory, so on UK/road-salt cars it rots from the inside out. The classic failure zones are the rear crossmember (which traps mud and water and bulges/perforates along its lower edge), the body-mount and… Repairs typically run $600-$5,000. Severity: high.
The 300Tdi's cast-iron cylinder head develops fine cracks between the valve seats and from the injector bore across to the inlet valve seat. These are almost always the result of a previous overheat or coolant loss — the head warps, the gasket fails, combustion gases push into th… Repairs typically run $500-$1,800. Severity: high.
The Td5 uses torque-to-yield (stretch) head bolts. Over miles and heat cycles they relax, the clamping load drops, and the head starts to 'float' on the block — which also deforms the plastic location dowels (the deformed dowels are a symptom, not the cause). Combustion gases the… Repairs typically run $600-$2,500. Severity: high.
The steel bulkhead rusts hard at the bottoms of the footwells, around the door pillars/A-posts and at the 'feet' where it bolts to the chassis outriggers. The factory double-plates (sheet over sheet) the footwells and the area above the transmission tunnel; water sits between the… Repairs typically run $300-$3,000. Severity: high.
The Achilles heel of the late 2.2 Puma (the Ford 'Global Puma' / Duratorq DW shared with the Transit). The internal oil pump can break up / lose drive, causing total oil starvation and catastrophic bottom-end failure with very little warning. Early-production EU5 engines (broadly… Repairs typically run $1,500-$6,000. Severity: high.
The Ford-sourced MT82 6-speed (fitted to every Puma) has a notorious dry spline where the rear output shaft mates into the LT230 transfer box. Because that spline runs effectively unlubricated, it 'frets' and wears away exactly like the earlier LT77/R380 mainshaft splines, eventu… Repairs typically run $600-$2,500. Severity: high.
The Puma kept a painted (not galvanised) steel ladder chassis, and the rear crossmember is the first thing to rot — it boxes water and mud around the towing/rear-body mounts and rusts from the inside out, often hidden under undseal. The chassis outriggers, rear inner wings and fu… Repairs typically run $350-$5,000. Severity: high.
When Rover stretched the alloy V8 from 89mm to 94mm bores for the 3.9, the parent-bore casting left as little as ~2mm of aluminium between the water jacket and the pressed-in iron 'parent bore' liner. There is no counter-bore or ridge at the bottom of the bore to locate the liner… Repairs typically run $2,500-$8,000. Severity: high.
Factory NAS chassis were NOT hot-dip galvanized. The boxed rear crossmember and the bulkhead/body outriggers are the first thing to rot: mud, road salt and trail debris pack into the box sections from the open ends and corrode them from the inside out, so a frame that looks tidy… Repairs typically run $600-$6,000. Severity: high.
The steel bulkhead is multiple spot-welded, double-skinned layers, and moisture wicks into the hidden joints. On NAS trucks the footwells, the A-pillar/door-pillar junctions and the top corners rot from the inside out, hidden behind trim and easily disguised with paint. Because t… Repairs typically run $500-$4,000. Severity: high.
The early manual NAS trucks (notably the 1994 D90) ran the LT77S five-speed, which does not cope with the V8's torque. It lacks the lubrication feed the later box has and strips its 2-3 synchro and gears — Land Rover replaced these under warranty across the 1994 NAS D90 fleet. Bo… Repairs typically run $1,500-$4,500. Severity: high.
The 200Tdi cylinder head has a known design weakness: the casting 'bridge' between the valve seats is very thin, and on a high-mileage or once-overheated engine it cracks across that bridge. The cracks let combustion gases into the coolant (and coolant loss), and a cracked head i… Repairs typically run $300-$1,500. Severity: high.
The pressed-steel front bulkhead is the single most expensive structural weak point on a 200Tdi-era Defender and the one restorers fear most. The lower outer corners (footwell box sections), the heater/fresh-air vent apertures, the windscreen-frame mounting flange, and the door-p… Repairs typically run $350-$3,500. Severity: high.
The 200Tdi-era ladder chassis left the factory only painted, never galvanised, so the boxed steel rusts from the inside where mud and water collect and cannot drain. The rear crossmember rots first (it fills with road debris and is hidden behind the rear tub), followed by the bod… Repairs typically run $250-$6,000. Severity: high.
Early 300Tdi engines (the 1994-mid/late-1996 build, before the factory mod) suffer a timing-belt alignment fault: the belt tracks against the edge of the idler/pulley and progressively shreds itself, or the front cover/seal lets oil onto the belt. A 300Tdi is an interference engi… Repairs typically run $150-$600. Severity: high.
On many early Td5 engines Land Rover never applied threadlock to the oil pump drive sprocket bolt behind the front timing cover. With nothing locking it, the bolt slowly works loose; once it backs off, the sprocket spins on the pump shaft without driving the pump. Oil pressure co… Repairs typically run $80-$6,000. Severity: high.
When Land Rover turbocharged the well-liked 2.5 naturally-aspirated diesel to create the 19J, they bolted the turbo on without adequately strengthening the bottom end. Owners and rebuilders report internal cracks developing in the cylinder block and cracked/holed pistons appearin… Repairs typically run $400-$4,000. Severity: high.
The early 90/110 left the factory with a painted (not galvanised) steel ladder chassis that begins corroding almost immediately. The rear crossmember sits directly in the spray off the rear wheels and is the first to go; the body-mount outriggers and the chassis rails around the… Repairs typically run $250-$4,500. Severity: high.
