The 2025 Renault Scenic E-Tech is brand-new to market, so long-term failure data is minimal. However, early patterns suggest suspension/subframe mounting issues and drivetrain seal leaks that mirror problems seen in the Megane E-Tech platform it shares architecture with.
Subframe Bushing Deterioration
Occasional · medium severityTypical onset: 30,000-50,000 mi
Symptoms: clunking over bumps, steering vagueness, uneven tire wear on inside edges, wandering feel at highway speeds
Fix: Subframe must be dropped to access bushings; typically replace all four corners at once. 4-5 hours labor for front subframe, 3-4 hours rear. Alignment mandatory after.
Estimated cost: $800-1,400
Rear Axle Seal Leaks
Occasional · medium severityTypical onset: 20,000-40,000 mi
Symptoms: gear oil spots on driveway, oil visible on inner CV boot or suspension components, whining noise from rear under acceleration
Fix: Axle must be pulled, seal replaced, refill differential. 2-3 hours per side. Often both sides weep eventually due to same-generation seals.
Estimated cost: $500-900
Front Differential Seal Failure
Occasional · medium severityTypical onset: 25,000-45,000 mi
Symptoms: oil pooling under front of vehicle, grinding or whirring from front axle during tight turns, low fluid warning on dash (some variants)
Fix: Front subframe partial drop required for access. Seal replacement plus differential service. 3-4 hours labor. Check for metal contamination in old fluid—may indicate bearing wear.
Estimated cost: $700-1,200
Transmission (Reduction Gear) Mount Failure
Common · low severitySymptoms: clunk when shifting from D to R or vice versa, vibration at idle in Drive, excessive drivetrain movement visible when rocking vehicle in park
Fix: Single or dual motor mounts (depending on EV60/EV87 variant). Mount(s) accessible from below, 1.5-2 hours labor. OE mounts are hydraulic-filled and fail early.
Estimated cost: $350-600
Rear Knuckle/Spindle Bearing Failure
Rare · high severityTypical onset: 40,000-70,000 mi
Symptoms: growling or humming from rear that increases with speed, ABS/traction control warning lights, wheel play detectable when jacked up
Fix: Knuckle assembly replacement (bearing is pressed/not serviceable separately on this platform). 2.5-3 hours per side including alignment check.
Estimated cost: $600-1,000
Transmission Oil Cooler Line Corrosion
Rare · medium severitySymptoms: gear oil dripping near front subframe, low fluid level in reduction gear, overheating warning during sustained highway use or towing
Fix: Lines run along subframe and corrode from road salt. Replacement requires partial subframe drop. 3-4 hours labor, flush and refill reduction gear fluid.
Estimated cost: $600-1,100
Too new to recommend used yet—wait until 2027-2028 models hit the market with 40-60k miles so we can see if early seal and bushing issues were production teething or inherent design flaws.
