VERDICT · A WELL-KNOWN, EXPENSIVE WEAK POINT
Land Rover Air Suspension
is it actually reliable?
The air suspension system fitted across most of the Range Rover lineup — genuinely excellent on-road comfort and off-road capability when functioning correctly, but one of the most consistently discussed sources of expensive repair bills in Land Rover ownership.

COMPONENTSAir springs, compressor, height sensors
FITTED TORange Rover, Range Rover Sport, Discovery
YEARS2002–present
The short version
Air springs, the compressor, and height sensors all degrade with age and are collectively among the most frequently repaired components across Land Rover's lineup — this isn't a rare edge case but a near-universal consideration for any vehicle old enough to be on the used market. Independent specialists generally treat air suspension condition as one of the first things to assess on any used Range Rover or Discovery, right alongside the engine itself.
Pros and cons
WHAT HOLDS UP
- Genuinely excellent ride comfort and off-road capability when functioning correctly
- Well documented after years of widespread use, making issues straightforward to diagnose
- Aftermarket conversion kits (to coil springs) exist as a permanent alternative for buyers prioritising reliability over the air system's specific capabilities
- A recently replaced or well-maintained system is a meaningfully safer bet than an original, aged one
WHAT FAILS
- Air springs degrade and leak with age, a near-universal issue on vehicles old enough to be on the used market
- Compressor failure is a common, moderately expensive repair
- Height sensor faults can cause uneven ride height or warning lights even when springs and compressor are sound
- Full system replacement across all four corners is a significant cost relative to the vehicle's used value on older examples
Where problems tend to appear
Not a guarantee, but a pattern seen consistently across owner forums and independent-garage reporting.
60,000–100,000 MIFirst air spring leaks or compressor strain become more commonly reported within this range.
100,000+ MIA full or partial air suspension overhaul becomes an increasingly realistic near-term cost to budget for.

Buying one — what to check
Observe the vehicle at rest after sitting overnight — a corner that's visibly lower than the others is a clear sign of an air spring leak.
Cycle the suspension through its height settings (where accessible) and listen for the compressor labouring or running excessively.
Ask whether any component has already been replaced, and get documentation — a partial replacement doesn't guarantee the remaining original components are sound.
