Land Rover Defender Repair and Service in Sherman Oaks, CA
Two completely different vehicles wear the Defender badge, and a shop that treats them the same will get both of them wrong. The classic Defender — the 90s and 110s built through the mid-1990s — is a mechanical truck that needs a technician who understands swivel housings and transfer cases. The current L663, launched in 2020, is a modern aluminium SUV with an Ingenium engine, a battery management system and a fault architecture it shares with the Range Rover Sport.
We work on both. We have been on Van Nuys Boulevard since 1977, which means we were servicing the first kind long before the second one existed, and every repair we perform is backed by our 1-year / 12,000-mile warranty.
The classic Defender: 90, 110 and 130
Old Defenders leak, and the question is only where from. The ones we chase most often are the front swivel seals, the transfer case, the front and rear differentials, the engine oil pan and the power steering pressure and return hoses. None of these are difficult jobs if you have done them before; all of them are expensive if someone guesses.
The other classic-Defender pattern is steering and front-end wear — tie rod ends and boots that have dried out and cracked — and tires that have aged out rather than worn out. A set that still has tread but is dry-rotted through the sidewalls is not safe, and we will tell you that plainly rather than sell you an alignment on top of it.
We also take on work most shops decline. We have converted a Defender 110 from a manual gearbox to an automatic, and we do full restoration-scale mechanical work on these trucks. If you have been told your Defender is too old or too odd to work on, that is a conversation worth having with us.
The new Defender (L663, 2020 onward)
The modern Defender shares its engine architecture with the rest of the current Land Rover range, which means it shares the faults. The one we see most is a coolant leak at the turbo cooler hose O-ring and the cylinder head coolant pipe — frequently both at once, and usually reported as a coolant message on the display rather than as a visible leak. Water pump failure is the other common cooling fault, and it typically arrives as a check engine light.
Beyond cooling, the faults we see are misfires (we perform a coil and spark plug swap test to confirm the cylinder before replacing anything), coolant flow control valves stuck closed, and active grille air shutter module communication faults. These are diagnosis jobs, not parts-cannon jobs.
One thing a general shop gets wrong on a new Defender
A battery replacement on an L663 is not just a battery replacement. The new battery has to be registered to the vehicle's battery management system, or the charging strategy stays calibrated to the old battery — which shortens the life of the new one and can produce faults that look like something else entirely. We register every battery we fit. It costs you nothing extra and it is the difference between a repair and a future problem.
Scheduled maintenance
We perform the full Defender interval schedule — 20,000, 45,000, 65,000 and 95,000 mile services and everything between — with the correct specification oil, engine air and pollen filters, tire pressures set and the service reminder reset properly. Having this work done by an independent specialist does not affect your factory warranty.
Classic or current, we know which Defender you have.
