A seriously underrated hot hatch with four-wheel steering and 280 hp from a 1.8-liter turbo. Popular with enthusiasts who appreciate its sharp handling and aggressive styling. Main concerns are the PK4 manual gearbox output bearing failure (clicking/droning noise), fuel pump failures on early cars (covered by recall), and battery drain issues particularly on RS 300 Trophy models with smaller DESS batteries. The EDC dual-clutch auto is reliable but can develop software glitches. Recaro seats in Trophy models creak. Renault's brand reliability ranks 23rd of 32 manufacturers, but reported RS problems are relatively few.
Output bearing or differential bearings fail, causing clicking/droning noise · more· less
The PK4 six-speed manual gearbox can develop bearing noise, typically from the output shaft bearing or limited-slip differential bearings. Symptoms include clicking/knocking at low speeds (under 4 mph) and a droning noise at higher speeds (above 35 mph) that persists in any gear, neutral, with clutch in or out. Typically occurs between 50,000-100,000 km. Renault changed the bearings in later models, and some batches are known to be inferior. Complete gearbox rebuild including removal costs around €1,200-1,500 at specialists. Renault dealers will replace the entire gearbox rather than rebuild, which can reach €2,200. Annual gearbox oil changes with quality GL-4+ oil (ELF TRANSELF NFP 75W-80 or Millers 75W-90) help prevent premature wear.
Fuel pump failure€400 - €800
Fuel pumps fail on 280/300 models, especially early production cars · more· less
All 280/300 models can suffer from fuel pump failure, with Phase 1 Megane RS 300 models particularly affected. Some owners have had two replacements. Symptoms include "Engine failure hazard" warning light, severe loss of power/juddering on motorway that goes away after cooling, or the car cutting out completely. A fuel pump recall exists for some 2019 RS 280 Cup models. If covered by recall, replacement is free. Otherwise, expect €400-800 for parts and labor. The related fuel control unit can also fail (covered under warranty if within period). Check with your Renault dealer using VIN to confirm if your car is affected by the fuel pump recall. Keep fuel level above 1/4 tank to maximize pump lifespan.
Battery drain / DESS battery issues€150 - €400
Lightweight DESS battery drains quickly, especially on RS 300 Trophy models · more· less
RS 300 Trophy models use a smaller 19Ah DESS (Dual Energy Storage System) battery that drains faster than the standard battery used in RS 280 models. With alarms and trackers drawing 0.85-1 amp, the battery can theoretically last only 19 hours. Symptoms include intermittent starting issues, "Power Steering Fault" warning when cold, or voltage dropping rapidly to 5.4V. Renault issued a battery management software update to address this - ensure your car has received this update. Some dealers replaced batteries without applying the software fix. After 5 years, batteries likely need replacement (use Platinum level or equivalent). A battery disconnect/reset (negative terminal off for 15-20 minutes) often clears faults. Cost: €150-200 for software update, €250-400 for new battery plus labor.
Recaro seat creaking (Trophy models)€300 - €800
Trophy Recaro seat base develops creak/grind noise, particularly during cornering · more· less
A common issue with Trophy Recaro Sportster CS seats is a terrible creaking or grinding noise from the seat base, especially noticeable during hard cornering when lateral forces push the driver against the bolster. The issue comes from the plastic backside of the seat or the seat base mechanism itself. Renault has replaced seat bases under warranty in the first year, but the problem can recur. Some dealers have replaced entire seat bases multiple times. The Recaro seats are road-compliant reclining two-part units (base + backrest) with integrated airbags, making replacement expensive. Non-warranty replacement costs €300-800 depending on whether just the mechanism or entire base is replaced. Check seat tightness and tighten floor bolts if needed.
Oil pressure solenoid valve failure€500 - €1,200
Solenoid valve fails to switch to high oil pressure, risking engine damage · more· less
There was a recall for the oil pressure solenoid valve on Megane RS models with M5P engine manufactured between 1 March 2018 and 31 May 2019 at the Palencia plant. The solenoid valve may not switch to the 'high oil pressure' position, potentially leaving the engine starved of oil and leading to catastrophic engine failure. Symptoms include oil pressure warning lights or unusual engine noises. This is a serious safety recall - verify with your Renault dealer using VIN that this recall has been completed. If covered by recall, replacement is free. Outside of recall or warranty, expect €500-1,200 for solenoid replacement and diagnosis. Related to this issue is the turbo oil feed pipe recall on some early cars.
EDC dual-clutch software glitches€0 - €2,500
EDC transmission develops jerky shifts or low-speed shudder, usually software-related · more· less
The wet-clutch DCT450 EDC gearbox in the Megane RS is mechanically strong and more reliable than dry-clutch units in smaller Renaults. However, it can develop software/electronic issues causing jerky gear changes or low-speed shudder. Many "gearbox failures" are resolved by TCM module reprogramming or software updates (typically free at dealers). The EDC doesn't like crawling in traffic constantly - it can overheat even in winter. In traffic, slip into neutral to reduce load. True mechanical failures (clutch pack wear, ECU faults) are rare but expensive - clutch pack alone can cost €2,500+, full replacement €4,500-13,000. With proper use (avoid constant traffic crawling, use neutral when stationary), the EDC should outlast a manual clutch. Software updates at dealers are typically free or €100-200. Terminal mechanical failures are uncommon.
Fuel gauge malfunction€200 - €500
Fuel gauge reading erratic - drops to empty at 1/4 tank then corrects itself · more· less
A common issue where the fuel gauge shows empty when there's still a quarter tank remaining, then suddenly jumps back to the correct level. Renault dealers have acknowledged this as "just one of those common problems" on the RS 280/300. The issue is typically related to the fuel sender unit in the tank rather than the gauge cluster itself. Some cases are resolved by software updates, others require fuel sender unit replacement. Cost ranges from €200 for software update/sensor cleaning to €500 for complete sender unit replacement including labor. While annoying, this is usually not a critical safety issue - just track your mileage manually and refuel regularly.
Front suspension knocking€150 - €400
Knocking noise from front suspension, typically drop links or bushings · more· less
Some owners report knocking from the front suspension that sounds like drop link issues. The Megane RS uses MacPherson struts with Renault Sport's PerfoHub geometry to reduce torque steer. Common causes include worn anti-roll bar drop links, control arm bushings, or strut top mounts. Cup chassis models with stiffer suspension can accelerate wear on these components. Drop links are relatively inexpensive (€80-150 for parts, 1-2 hours labor). Control arm bushings cost €150-250 plus labor. Top mounts €100-200 plus labor. The stiff Cup suspension is excellent for track work but can be harsh on normal roads, contributing to component wear. Have suspension inspected for play or torn boots during service.
Reliable for a hot hatch, but not German-level build quality
The Megane RS 280 is "seriously underrated" according to serial Renault Sport owners. With the current generation, reported problems are relatively few compared to earlier RS models. The main issues are well-documented (gearbox bearings, fuel pump, battery) and most have recalls or known fixes. Renault ranks 23rd of 32 manufacturers for reliability, but the RS models benefit from stronger components and dedicated engineering. Budget for typical hot hatch wear items and enthusiast-driven maintenance.
Pre-Purchase Inspection Checklist
General checks
Service history
Complete service records essential - RS models need 12-month/12,000-mile intervals. Verify oil changes at proper intervals with correct spec oil.
Tires
Check Bridgestone Potenza S001 245/35 R19 tires for tread depth, age (date codes), and uneven wear. Front tires wear quickly with enthusiastic driving.
Cold start
Must start engine completely cold. Listen for unusual noises, check battery warning lights.
Body condition
Check front bumper, side skirts, and rear diffuser for track/curb damage. Inspect wheels for kerbing.
Test drive
Minimum 30 minutes including varied conditions - town traffic, highway, and spirited cornering to test 4-wheel steering.
Specific for this vehicle
Manual gearbox bearing noise
Listen for clicking/knocking under 4 mph and droning noise above 35 mph in any gear. Check in neutral and with clutch engaged/disengaged. This is the most critical check for manual cars.
EDC gearbox operation (if auto)
Drive for 20+ minutes including stop-start traffic. Feel for jerky shifts, hesitation, or shudder at low speeds. EDC should shift smoothly when warm.
Battery and electrical system
Check battery voltage (should be 12.6V+ when off). Look for "Battery Low" warnings. On RS 300 Trophy, verify DESS battery software update completed. Test all electrics including power steering.
Recaro seat condition (Trophy models)
Sit in seats and rock side-to-side to check for creaking/grinding. Check seat adjustment mechanisms and bolster wear. Recaro replacements are expensive.
Fuel pump recall verification
Contact Renault dealer with VIN to verify fuel pump recall completion (affects some 2019 models). Check for "Engine failure hazard" warnings in history.
Oil pressure solenoid recall (2018-2019 production)
Critical safety recall for cars built March 2018 - May 2019. Verify with dealer using VIN that this recall has been completed before purchase.
Front suspension knocking
Drive over speed bumps and rough roads. Listen for knocks from front suspension. Check drop links, bushings, and top mounts for play.
Fuel gauge accuracy
Check that fuel gauge reads correctly. If it drops to empty at 1/4 tank, this is a known issue but should be disclosed.
Check brake pad/disc condition
Brembo brakes wear quickly with enthusiastic driving. Check pad thickness and disc condition. Budget €400-800 for full brake replacement if needed soon.
Verify service plan / warranty status
Check if car has remaining manufacturer warranty or extended warranty. Renault offers extended warranty for around €370/year - valuable for RS models.
