Land Rover Discovery Sport Common Faults in the UK
L550 (2015–2026) — A premium, five/seven-seat compact SUV positioned below the full-size Discovery in Land Rover's range, competing with the Audi Q5, BMW X3 and Volvo XC60. Updated 2026-08-30.
The Land Rover Discovery Sport (2015–2026, L550) is a premium seven-seat-capable compact SUV that has consistently scored poorly in What Car?'s reliability survey, with owners reporting faults on roughly a third of cars, most often air-con, engine electrics and infotainment. The single most important thing to check on any used example is the timing chain on the 2.0-litre Ingenium diesel engine: a rattle on cold start is an early warning sign of a fault that can destroy the engine if ignored, so listen carefully before buying and ask for proof of any chain-related work. Early cars from the 2015–2017 launch period are the ones to treat with most caution, combining the least mature version of the Ingenium diesel with the buggiest first-generation InControl Touch Pro software and a wiring-harness recall. A 2021–2023 car with full service history, a recorded Haldex/driveline fluid change, and confirmation via the gov.uk recall checker that all recall work has been carried out is the safer used buy.
84.5% of Land Rover Discovery Sports pass the MOT first time, 1.1 points better than the national average for cars of the same age (83.4%). Counted from 12,812 DVSA tests.

Best and worst years to buy
From the late-2019/2020 facelift onward, the Discovery Sport gained second-generation Ingenium engines, a revised 9-speed automatic calibration and the dual-screen Touch Pro Duo infotainment. By 2021–2023 these had several years of running production fixes behind them and are far less associated with the early timing-chain and infotainment complaints that dog launch-period cars — though a full service history covering Haldex fluid changes and confirmed recall work is still essential on any year.
The 2015–2017 launch cars combined the least mature version of the Ingenium diesel engine (introduced partway through 2015) with first-generation InControl Touch Pro infotainment software — the two most-reported problem areas in owner forums and reliability surveys — plus the 2016–2017 wiring-harness recall. Buyers should be especially thorough checking service history and recall status on cars from this period.
Known faults — Land Rover Discovery Sport L550 (2015–2026)
Documented from HonestJohn, owner forum sentiment (PistonHeads, Reddit), and the DVSA recall portal. Severity is colour-coded.
Engine — timing chain (2.0 Ingenium diesel)
Critical — engine-out potential- Symptoms
- A rattle or chain-slap noise on cold start that quietens as the engine warms up; in advanced cases, an engine warning light, rough running, or sudden loss of power. If the chain jumps timing or snaps, this can mean catastrophic engine damage.
- Years affected
- 2015–2018, concentrated on the earliest Ingenium diesel units introduced from September 2015; isolated reports continue on later diesels — Reports from as low as 40,000–60,000 miles, though failures have occurred later — treat any cold-start rattle as urgent regardless of mileage
- Indicative repair (UK)
- Roughly £1,800–£2,500 at an independent specialist for chain, tensioner, guides and seals; £4,000+ for a replacement or rebuilt engine if the fault is ignored and it fails
- What to check before buying
- Listen to a cold start (ideally the car's first start of the day) for 10–15 seconds for any rattle before it settles; check the service history for any chain-related work or oil-dilution checks; check oil level and condition.
Recalls — engine wiring harness and 48V electrical system
Critical — engine-out potential- Symptoms
- On 2016–2017 cars with the 2.0-litre engine and automatic gearbox, chafing of the engine wiring loom against the charge-air-cooler bracket can cause a warning light, loss of power-steering assistance, the engine cutting out without warning, or in extreme cases an under-bonnet fire. Separately, some 2019–2020 mild-hybrid (MHEV) cars were recalled over a 48V electrical system fault.
- Years affected
- 2016–2017 (wiring harness chafe, cars built July–October 2016); 2019–2020 (48V mild-hybrid system) — Not mileage-related — depends on build date/VIN, not miles covered
- Indicative repair (UK)
- Free of charge as a manufacturer recall — but always confirm the work was actually carried out before buying
- What to check before buying
- Run the registration/VIN through the free gov.uk vehicle recall checker (check-vehicle-recalls.service.gov.uk) and look for a dealer stamp or invoice confirming any outstanding recall was completed.
Transmission — 9-speed automatic gearbox
Major — significant repair cost- Symptoms
- Hesitation pulling away from a standstill, jerky or delayed gearchanges, harsh kickdown, or occasionally the gearbox defaulting into neutral with a warning message.
- Years affected
- Reported across the range on automatic cars, 2015–2023 — Can appear from relatively low mileage; most reports come from cars beyond 30,000–40,000 miles still on original transmission fluid
- Indicative repair (UK)
- Often free–£200 for a software reflash and adaptation reset at a dealer or specialist; £1,500–£3,000+ for a mechatronic unit or gearbox replacement if the fault is a wiring/sensor issue inside the unit
- What to check before buying
- On the test drive, pull away from a stop several times and try a full-throttle kickdown; feel for hesitation, jerkiness or a flare before a gear engages. Ask when the transmission fluid was last changed.
Drivetrain — four-wheel-drive coupling (Haldex-type)
Major — significant repair cost- Symptoms
- A 4WD or driveline warning message, vibration or judder on tight, low-speed turns, and reduced traction or a car that behaves as front-wheel-drive only.
- Years affected
- All years, 2015–2026 — risk rises with age and mileage rather than being tied to a specific model year — Most commonly reported from around 60,000–90,000 miles, worse where the periodic driveline fluid change has been skipped
- Indicative repair (UK)
- £150–£300 for a driveline fluid and filter service; £800–£1,500 for a clutch-pack rebuild or coupling replacement if worn
- What to check before buying
- Ask for evidence of a Haldex/rear-driveline fluid change (Land Rover recommends this periodically); on the test drive, do several full-lock, low-speed turns on tarmac and listen/feel for vibration or juddering.
Infotainment — InControl Touch Pro / Touch Pro Duo
Major — significant repair cost- Symptoms
- The touchscreen freezing, rebooting, or going completely black; Bluetooth and smartphone connectivity dropping out; sat-nav or reversing camera failing to load.
- Years affected
- Most reported on 2015–2019 cars with the original InControl Touch Pro system; still occurs, less frequently, on 2020-on cars with the dual-screen Touch Pro Duo — Not mileage-related — a software/electrical fault that can appear on any mileage
- Indicative repair (UK)
- Free if resolved by a dealer software update under warranty; roughly £300–£800 for a screen or infotainment module replacement out of warranty
- What to check before buying
- Spend time working through the touchscreen — pair a phone by Bluetooth, use the reversing camera and sat-nav, and watch for any freezing, rebooting, or blank screens during the test drive.
Air conditioning
Minor — wear-and-tear- Symptoms
- Air con blowing warm or only mildly cool air, an audible compressor rattle or clutch noise, or the system cycling on and off unexpectedly.
- Years affected
- Most commonly reported on 2015–2017 cars (some left the factory under-filled with refrigerant), but occurs across the range as systems age — Not strongly mileage-related, though seals and compressors are more likely to show wear on higher-mileage or older cars
- Indicative repair (UK)
- £100–£150 for a regas and leak check; £400–£800 for compressor replacement if that's the cause
- What to check before buying
- Run the air conditioning for several minutes on a warm day and check it blows consistently cold from all vents; ask if and when it was last regassed.
Who this car suits — and who should look elsewhere
Buyers wanting genuine 7-seat practicality and off-road ability with a premium badge, and prepared to budget for Land Rover-specific servicing. A 2019+ Ingenium-engined car with full main-dealer or specialist history is the safer buy.
Anyone without a specialist pre-purchase inspection budgeted in — this is one of the more electrically and mechanically complex cars in this price range. A pre-2018 car without a fully stamped service history.
