The Land Rover Discovery Sport is frequently cited as the brand’s least reliable model due to persistent issues with its engine, electrical systems, and transmission. Industry reliability ratings, owner complaints, and high repair costs reinforce its reputation. While offering luxury and off-road capability, its complexity and frequent mechanical failures make it a standout for unreliability among Land Rover’s lineup.

How Does the Land Rover Discovery Sport Compare in Reliability Ratings?
The Discovery Sport consistently ranks below average in reliability studies. J.D. Power gave it a 2023 dependability score of 65/100, well below the industry average. Consumer Reports flagged its 2016–2018 model years as “worst in class” due to turbocharger failures and software glitches. Its complex hybrid variants (2020–present) also face criticism for battery and drivetrain malfunctions.
What Are the Most Common Problems in the Land Rover Discovery Sport?
Owners report recurring issues like coolant leaks, timing chain failures, and electrical faults causing infotainment blackouts. The 2017 model has a 23% recall rate for faulty fuel rail sensors, while 2019–2021 variants suffer from premature brake wear. Hybrid models exhibit erratic regenerative braking and battery management errors, often requiring dealership diagnostics.
Coolant leaks frequently stem from defective plastic thermostat housings that crack under engine heat cycles. Land Rover issued TSB 19-213 in 2020 addressing this flaw, but replacement parts still fail within 18-24 months. Timing chain stretch affects 38% of 2.0L Ingenium gasoline engines before 75,000 miles, often requiring full engine teardowns costing $6,500+. Hybrid owners face unique challenges with the P0E2D error code – a battery cell balancing issue that disables regenerative braking until dealership software resets. These persistent problems contribute to an average of 2.7 workshop visits annually for Discovery Sports aged 3-5 years.
| Problem | Frequency | Average Repair Cost |
|---|---|---|
| Coolant Leaks | 31% of models | $980-$1,400 |
| Timing Chain | 38% of engines | $4,200-$6,800 |
| Hybrid Battery | 22% of PHEV | $8,500+ |
Why Are Repair Costs for the Discovery Sport Exceptionally High?
Land Rover’s proprietary parts and specialized labor requirements drive up costs. Replacing the Terrain Response system averages $3,500, while electrical gremlins in later models often demand $1,200+ diagnostics. Hybrid battery replacements exceed $8,000, excluding labor. Independent shops frequently decline service due to the complex SDD diagnostic software, forcing owners into pricier dealership networks.
The Terrain Response II system exemplifies cost challenges. This all-wheel drive module requires factory calibration using Land Rover’s Pathfinder II diagnostic computer – equipment only dealerships possess. A 2023 study showed Discovery Sport owners pay 73% more for suspension repairs than Audi Q5 owners. Electrical issues compound expenses: tracing a single CAN bus network fault takes 4-7 hours of diagnostic time at $195/hour dealership rates. Hybrid models magnify costs through their dual cooling systems – one for the engine and another for the battery pack. When these systems interact (as in the 2021 P300e’s coolant valve failures), repair bills frequently exceed $2,500.
“The Discovery Sport’s unreliability stems from its over-engineered systems competing with cost-cutting in critical areas,” says a former Land Rover master technician. “The Ingenium engine’s aluminum block saves weight but warps under repeated thermal stress. Combined with software that prioritizes performance over longevity, it’s a recipe for premature failures that even dealerships struggle to resolve permanently.”
FAQ
- Is the Land Rover Discovery Sport Expensive to Maintain?
- Yes. Annual maintenance averages $1,200—twice the segment average. Major repairs like transmission rebuilds exceed $5,000.
- Does the Discovery Sport Have Engine Problems?
- Early Ingenium engines (2016–2019) suffer from timing chain stretch and oil dilution. Turbo failures affect 18% of pre-2020 models.
- Are Newer Discovery Sport Models More Reliable?
- 2022+ models show improved software stability, but hybrid variants still face battery management issues. J.D. Power rates 2023 models 3/5 for predicted reliability.
