Range Rover Sport (L494) Reliability & Used Buyer's Guide

The second-generation Range Rover Sport (L494, 2014-2022) is Land Rover’s best-selling model. By switching to an all-aluminum chassis, it shed 800 pounds compared to the previous generation, vastly improving handling, acceleration, and fuel economy.

However, stripping weight did not strip away the classic British electrical gremlins or the notorious maintenance costs. If you are buying a used Range Rover Sport, you must understand the massive difference in reliability between the V6 and V8 models, and prepare for chronic suspension wear.

Engine Choices: The Safe Bet vs The Risk

The L494 was offered with a bewildering array of engines: Supercharged V6s, Supercharged V8s, Turbo-Diesels (Td6), and later inline-6 Mild Hybrids.

1. The 3.0L Supercharged V6 (The Safe Bet): This is essentially the 5.0L V8 with two cylinders blanked off. It shares the same engine block architecture. Crucially, it generally avoids the catastrophic timing chain disaster of the V8. However, it still suffers from the exploding plastic coolant crossover pipes. Replace the plastic pipes at 50,000 miles, and the V6 is surprisingly stout.
2. The 5.0L Supercharged V8 (The Financial Risk): Available in the “Supercharged” and “SVR” trims. The 510-575 horsepower output is addictive, but it carries the massive, well-documented risk of timing chain guide failure and severe overheating if the cooling system is neglected. Do not buy a pre-2018 V8 without a $10,000 repair fund.
3. The 3.0L Td6 Diesel: Excellent fuel economy, but cursed with diesel emissions equipment failures (DPF clogging, DEF pump failure) if used for short city trips. Avoid unless you commute 50+ miles on the highway daily.

Chassis & Suspension Woes

The Range Rover Sport handles incredibly well for an SUV, thanks to its complex air suspension and (on V8/Dynamic models) a hydraulic active anti-roll system.

Air Suspension Attrition

Every L494 uses a 4-corner air suspension system. The rubber air struts themselves are fairly durable, often lasting to 100,000 miles. However, the Hitachi/AMK air compressors fail frequently around 60,000 miles due to a faulty exhaust valve design that allows moisture into the system, burning out the motor.

Active Roll Control Leaks

Dynamic models feature hydraulic anti-roll bars. The valve block controlling the fluid pressure is located under the passenger side of the car, exposed to road salt and debris. Over time, the internal seals fail, leaking expensive hydraulic fluid. A dashboard warning light reading “Suspension Fault: Stop Safely” usually indicates a $3,500+ repair.

Lower Control Arms

Expect to replace the massive front lower control arms every 50,000 miles. The fluid-filled bushings tear under the stress of hard braking, causing a distinct clunk over speed bumps and a “wandering” feeling at highway speeds.

The Electrical Gremlins

Land Rover’s electronics are infamous. The L494 features the older “InControl Touch” interface in early years, which is notoriously slow and prone to freezing.

• Door Latches: The soft-close door mechanisms and latch actuators frequently fail, preventing the door from locking or shutting entirely.
• Keyless Entry: The keyless entry antennas in the door handles short out randomly.
• Battery Drain: Like all modern luxury cars, a weak AGM battery will cause the Range Rover to throw dozens of phantom cascade errors (e.g., “Gearbox Fault” when the gearbox is perfectly fine).

Verdict

The Range Rover Sport L494 is a spectacular vehicle when it is working properly. If you want the look and feel without the catastrophic engine bills, seek out a 2016-2018 3.0L Supercharged V6 model. Immediately replace the coolant crossover pipes upon purchase, budget $1,500 annually for suspension wear, and enjoy one of the most capable luxury SUVs on the market.
