The 2024 Range Rover with 3.0L I6 mild hybrid is extremely new to market, but early warranty data and recalls point to concerning powertrain issues uncharacteristic of a luxury flagship—engine internal failures and transmission cooling problems are appearing far too early.
Premature Engine Internal Failure (Pistons, Bearings, Crankshaft)
Occasional · high severityTypical onset: 5,000-25,000 mi
Symptoms: Severe knocking or rattling from engine at idle or acceleration, Metal shavings in oil during early services, Check engine light with low oil pressure codes, Catastrophic loss of power
Fix: Complete engine rebuild or short block replacement required. This is warranty-covered if under 50k miles, but involves 25-35 labor hours for R&R and rebuild. Independent shops seeing grenaded engines with piston ring failures and bearing wear that shouldn't happen this early.
Estimated cost: $15,000-28,000
Transmission Oil Cooler Failure
Common · high severityTypical onset: 8,000-30,000 mi
Symptoms: Transmission overheating warnings on dash, Harsh shifting or delayed engagement, Transmission fluid leaking near radiator area, Limp mode activation
Fix: Oil cooler replacement requires dropping transmission pan, flushing system, and replacing cooler assembly. 6-9 hours labor. Cross-contamination between coolant and ATF can destroy transmission if not caught early—flush both systems immediately.
Estimated cost: $2,800-4,500
DC/DC Converter Failure (Mild Hybrid System)
Occasional · medium severitySymptoms: Battery warning light, Electrical system malfunctions (infotainment resets, camera failures), Vehicle won't start despite charged 12V battery, Mild hybrid system disabled message
Fix: DC/DC converter manages power between 48V mild hybrid system and 12V electrical system. Replacement requires disconnecting high-voltage system (safety protocols add time), 4-6 hours labor. This is a recall item but failures still occurring post-recall.
Estimated cost: $2,200-3,800
Backup Camera System Failure
Common · low severitySymptoms: Intermittent blank screen when shifting to reverse, Camera shows 'service required' message, Complete loss of rear camera view, Surround-view cameras not activating
Fix: Usually software-related but sometimes requires camera module replacement. Recall-covered for some units, but affected vehicles outside recall scope need camera module and wiring harness inspection. 2-3 hours labor for physical replacement.
Estimated cost: $1,200-2,100
Defective Engine Oil Filter Housing (Recall)
Occasional · high severitySymptoms: Oil leaking from filter housing area, Rapid oil loss between services, Oil pressure warning light, Burning oil smell from engine bay
Fix: Factory oil filter housing can crack or seal improperly, leading to catastrophic oil loss. Recall-covered replacement of housing assembly, 3-4 hours labor. Check VIN for recall eligibility immediately—DO NOT ignore oil leaks on this engine.
Estimated cost: $800-1,400
Transmission Mount Failure
Common · medium severityTypical onset: 15,000-40,000 mi
Symptoms: Excessive vibration during acceleration or deceleration, Clunking when shifting from park to drive, Drivetrain shudder at low speeds, Visible transmission sag when inspecting undercarriage
Fix: Hydraulic transmission mounts failing prematurely, likely due to weight and torque of hybrid powertrain. Replacement requires supporting transmission, 3-5 hours labor. Replace both mounts even if only one shows visible failure.
Estimated cost: $1,400-2,200
Hard pass for used buyers unless fully certified with extended powertrain warranty—seeing catastrophic engine failures at mileages where you're still making payments is unacceptable at this price point.
