The 2018 Range Rover Sport (L494) sits mid-cycle, offering the supercharged 3.0L V6, supercharged 5.0L V8, Td6 diesel, and the SVR's 575-hp V8. Aluminum body, air suspension, and ZF 8-speed are excellent on paper. In ownership reality, this is among the most repair-heavy luxury SUVs sold: EAS failures, infotainment crashes, oil leaks, and electrical gremlins.
Among the least reliable luxury SUVs sold. EAS air suspension, supercharger oil leaks, infotainment crashes, and timing chain stretch on V8s are well-documented. Extended warranty is essentially mandatory.
EAS compressor and air-strut leaks are the #1 complaint. Vehicle drops overnight or refuses to raise. Common 60K-90K mi.
Run free diagnosis →Twin-screen InControl Touch Pro freezes, loses CarPlay, and reboots randomly. Several JLR software bulletins issued. Some units replaced under warranty.
Run free diagnosis →Supercharged 5.0L V8 (AJ133) has documented timing chain tensioner failures, especially under extended idle. Listen for cold-start rattle and treat as urgent.
View P0017 Diagnosis →Plastic coolant crossover pipes and hoses develop leaks at hot/cold cycles, typically 60K-100K mi. Aluminum aftermarket pipes are a common fix.
Run free diagnosis →Modules stay awake too long, killing the AGM battery. Trickle chargers and frequent driving help. Coded replacement required.
View P0562 Diagnosis →Same diesel issues as Discovery: EGR cooler cracks and DPF clogging. NHTSA investigated JLR diesel emissions controls.

Magnificent on-road and off-road, deeply problematic to own out of warranty. CPO with remaining warranty is the only sensible buy. Cash purchase: budget $3K-$6K per year for repairs in years 5-8.
Middle of the L494 generation. Software is more mature than 2014-2016, but core EAS and electronics issues persist. The 2022 L461 next-gen brought meaningful improvements.
Expect $1,500-2,500/year in routine maintenance. Lifetime non-routine cost commonly $8,000-15,000 to 100K miles. Many owners describe it as the most expensive vehicle they have ever operated.

If your 2018 Range Rover Sport is throwing a check engine light, these are the codes most often associated with the problems above. Click any code for full diagnosis steps and typical repair costs.
No - well below average. JLR sits near the bottom of every major reliability survey, and the Sport reflects that.
Electronic air suspension (EAS) leaks and compressor failures, followed by InControl Touch Pro infotainment crashes.
Yes - the supercharged 5.0L AJ133 V8 has documented timing chain tensioner failures, especially with extended idling. Cold-start rattle is a red flag.
Only if you mostly do short trips. Short-distance use stresses the EGR cooler and clogs the DPF.
Yes - several, including driveline and emissions-related items. Check NHTSA by VIN.
120,000-150,000 miles is realistic. Repair costs typically force owners out before mechanical death.
