The 2024 Renault R5 E-Tech is a brand-new electric city car built on Renault's CMF-BEV platform. Too early for meaningful long-term failure data, but early production units and platform siblings show drivetrain mount fatigue and subframe bushing wear from the battery weight and instant torque delivery.
Drivetrain Mount Failures (Motor and Reducer Mounts)
Occasional · medium severityTypical onset: 15,000-30,000 mi
Symptoms: Clunking or thudding on hard acceleration or regen braking, Vibration through floorpan at idle (when climate system runs), Visible sag or tear in rubber mount visible from underneath
Fix: Replace failed motor mount or reducer mount; electric drivetrain must be supported while mount is swapped. 1.5-2.5 hours labor depending on which mount. OE part availability has been spotty in first production year.
Estimated cost: $400-750
Front Subframe Bushing Deterioration
Occasional · low severityTypical onset: 20,000-40,000 mi
Symptoms: Clunking over bumps or during direction changes, Steering feels vague or 'floaty' at highway speeds, Uneven inner tire wear on front tires
Fix: Replace front subframe bushings (set of four); subframe must be dropped for access. Requires alignment afterward. 3-4 hours labor. The battery pack weight accelerates bushing wear on this lightweight platform.
Estimated cost: $600-950
Rear Axle Seal Leaks (Reduction Gearbox Oil)
Rare · medium severityTypical onset: 10,000-25,000 mi
Symptoms: Small oil spots under rear of vehicle after parking, Visible oil residue on inner side of rear wheel or suspension components, Whining or growling noise from rear drivetrain under load
Fix: Replace rear axle seal at reduction gearbox output shaft. Halfshaft must be removed, seal pressed in, fresh gearbox oil refilled. 2-2.5 hours per side. Early production units had seal fitment issues that Renault addressed via TSB.
Estimated cost: $450-700
Rear Knuckle/Hub Assembly Corrosion (Salt-State Issue)
Rare · medium severitySymptoms: Grinding or scraping noise from rear wheel area during turns, Excessive play in rear wheel when jacked up and wiggled by hand, ABS or traction control warning lights
Fix: Replace rear knuckle/hub assembly. Early European-market cars showed accelerated corrosion on rear hubs in winter climates; suspect inadequate coating. 2 hours per side including alignment check. Parts availability improving as production ramps.
Estimated cost: $550-850
Thermal Management System Leaks (Coolant for Battery/Motor)
Rare · high severityTypical onset: 5,000-20,000 mi
Symptoms: Low coolant warning on dashboard, Sweet smell (glycol) in cabin or near front of vehicle, Reduced charging speed or 'drivetrain temperature' warning, Visible coolant pooling under front or center of vehicle
Fix: Locate and replace leaking coolant line, radiator, or heat exchanger in battery thermal circuit. System is under pressure and must be evacuated and refilled with specific coolant mix. 2-5 hours depending on component location; underbody panels and battery skid plate removal often required.
Estimated cost: $800-2,200
Too new to recommend used unless CPO with full warranty extension; wait for 2026+ model years after early production gremlins are sorted.
