The 2022 Range Rover Sport with the 3.0L supercharged V6 is a late-generation L494 platform vehicle. While newer than the problematic earlier years, it still inherits Land Rover's characteristic electrical gremlins and some serious powertrain vulnerabilities, particularly catastrophic engine failures tied to oil system defects.
Catastrophic Engine Failure - Oil Starvation / Bearing Failure
Occasional · high severityTypical onset: 30,000-70,000 mi
Symptoms: Sudden severe knocking or rattling from engine, Metal shavings in oil during routine service, Check engine light with low oil pressure codes, Complete loss of power / seized engine
Fix: This supercharged V6 suffers from oil pump and lubrication system defects causing bearing failure. Fix requires complete engine rebuild or short block replacement. 25-35 hours labor depending on extent of damage. Many cases covered under extended warranty if still active, otherwise catastrophic expense.
Estimated cost: $12,000-18,000
Transmission Oil Cooler Failure
Common · high severityTypical onset: 40,000-80,000 mi
Symptoms: Transmission overheating warnings, Harsh or delayed shifting, Milky or contaminated transmission fluid, Loss of drive / limp mode
Fix: The ZF 8-speed transmission cooler develops internal leaks allowing coolant and ATF to mix, contaminating both systems. Requires cooler replacement, full transmission flush, and often radiator service. If caught late, transmission rebuild needed. 8-12 hours labor for cooler and flush alone.
Estimated cost: $2,800-4,500
DC/DC Converter Failure (Hybrid System Component)
Occasional · medium severitySymptoms: 48V mild-hybrid system faults, Check engine light with electrical system codes, Loss of stop-start function, Battery drain / no-start conditions
Fix: The 48V mild-hybrid DC/DC converter fails, affecting start-stop and regenerative functions. NHTSA recall issued but many fail outside recall scope. Replacement requires software calibration and high-voltage safety protocols. 3-5 hours labor.
Estimated cost: $2,200-3,800
Backup Camera System Failure
Common · low severitySymptoms: Intermittent or complete loss of rear camera display, Blank screen when shifting to reverse, Parking sensor malfunctions, Surround-view camera glitches
Fix: Multiple NHTSA recalls for backup camera failures. Issues range from camera module failure to wiring harness corrosion to software glitches in the InControl Touch Pro system. Diagnosis can be time-consuming. 2-6 hours labor depending on root cause.
Estimated cost: $800-2,500
Transmission Mount Deterioration
Common · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Clunking when shifting from Park to Drive, Excessive vibration at idle, Harsh engagement on acceleration, Visible drivetrain movement
Fix: Engine and transmission mounts wear prematurely, especially with supercharged engine torque. Rear transmission mount most common failure. Replacement straightforward but requires supporting powertrain. 2-4 hours labor for mount replacement.
Estimated cost: $600-1,200
Seatbelt Pretensioner Malfunction
Occasional · high severitySymptoms: Seatbelt warning light illuminated, Airbag system warning, Seatbelt fails to retract properly, Clicking or rattling from B-pillar
Fix: NHTSA recalls for both retractor and pretensioner failures. Pretensioner may deploy inadvertently or fail to deploy in crash. Requires complete seat belt assembly replacement and airbag system reset. 2-3 hours labor per seat.
Estimated cost: $1,200-2,000
Hard pass unless you have a comprehensive warranty covering powertrain and electronics — the catastrophic engine failure risk alone makes this a gamble no rational buyer should take on their own dime.
