Land Rover Defender 90 / 110 / 130 (1983-2016) problems
Bodywork/ChassisHigh severity📝 Editorial
Rot in the steel front bulkhead, concentrated in the footwells, the corners around the windscreen frame, and behind the fresh-air vent flaps. The aluminium body panels never rust, which lulls buyers, but the bulkhead is structural steel, carries the door pillars and windscreen, and is one of the most expensive things on a Defender to put right; a full replacement means substantially dismantling the front of the vehicle.
Rough guide
£500-4000
Typical symptoms
flaky or holed metal in the front footwells, felt through the carpet or mats
bubbling and staining around the windscreen frame corners and vent flaps
doors dropping or shutting badly because the pillar mounts are going
damp front footwells after rain

Bodywork/ChassisHigh severity📝 Editorial
Chassis rot in the rear crossmember, the outriggers and the body mounts, which act as mud traps and corrode from the inside. The rear crossmember is one of the most commonly replaced components on a Defender, and outrigger replacement is labour-heavy welding. All of it is load-bearing, so perforation is an MOT structural failure.
Rough guide
£300-1500
Typical symptoms
flaking or holed metal on the rear crossmember behind the bumper
soft or crusty outriggers under the door sills
a new crossmember visibly newer than the rest of the chassis (previous rot, ask what else was done)
corrosion advisories or welding history in the MOT record

Where this Land Rover Defender fault data comes from
If you used to check the Honest John “Good & Bad” section before the site closed in 2026, this page is where that information now lives. We rebuilt the Land Rover Defender owner-report history from the archived Honest John dataset, added our own research, specialist and owner-club sources and DVSA recall data, and we keep it free. Each fault above is badged with its source. The same data feeds our free advert check, which reads a listing against every known fault for the exact engine and year.
Knowing what a Land Rover Defender goes wrong with is half of it. The rest is reading the advert and checking the car's history before you hand any money over.
