Air Suspension: The Most Reported Issue Across the Lineup
Nearly every modern Range Rover, Range Rover Sport, and Discovery uses air suspension to deliver its signature ride quality and adjustable height, and it's consistently the single most frequently reported issue owners search for. The system relies on rubber air springs at each corner, a compressor to maintain pressure, valve blocks to route air, and height sensors to keep everything level. Any of these components can wear or develop a leak over time, and rubber bags in particular degrade with age and heat cycling.
The way this typically unfolds matters for prevention: a small, slow leak doesn't cause an immediate problem, but it forces the compressor to run more often to compensate, and that extra cycling wears the compressor out faster than it should last. By the time a corner is visibly sagging or the vehicle can't hold its set ride height, you're often looking at a compressor replacement on top of whatever caused the original leak. Catching a slow leak early, before the compressor has been run into the ground compensating for it, is a meaningfully smaller and cheaper repair.
The Ingenium Diesel Timing Chain
If you own a Discovery Sport, Range Rover Evoque, or diesel-equipped Discovery from 2015 or later with the 2.0L Ingenium diesel, this is genuinely worth understanding. The timing chain on this engine is mounted at the rear, a design that theoretically should last the life of the vehicle, but a combination of factors has led to real, widespread premature failure. When the diesel particulate filter doesn't fully complete its regeneration cycle, often because the vehicle is driven mostly on short trips that never let exhaust temperatures reach what's needed, unburned diesel fuel can seep past the rings and dilute the engine oil. That diluted oil doesn't lubricate the timing chain as well as it should, and the chain, guides, and tensioner wear faster as a result.
The first sign is a metallic rattle at cold start, easy to dismiss as a minor noise on an otherwise fine-running engine. Left unaddressed, the chain can stretch enough to throw valve timing out of phase, leading to misfires and power loss, and in serious cases, the chain can snap entirely, letting pistons strike the valves and causing damage that's rarely economical to repair. Land Rover's own service documentation acknowledges oil dilution as a genuine concern once it crosses a measurable threshold, which is exactly why oil analysis and shortened change intervals, rather than the stretched factory interval, are worth doing on these engines. Taking the vehicle on periodic longer highway drives to let the DPF fully regenerate helps too. Vehicles built from around 2020 onward are understood to have benefited from design revisions that reduced this issue, so if you're shopping for a used Land Rover with this engine, confirming whether the update has already been done is worth the effort.
