The 2017 Twingo III is a rear-engine, rear-drive city car sharing its platform with the Smart Fortwo. The 0.9L turbo three-cylinder is problematic with timing chain and oiling issues, while the naturally-aspirated 1.0L SCe is significantly more reliable but underpowered.
0.9L TCe Timing Chain Premature Stretch and Failure
Common · high severityTypical onset: 40,000-80,000 mi
Symptoms: Rattling noise on cold starts that quiets after a few seconds, Check engine light with camshaft position correlation codes, Rough idle and loss of power, Catastrophic engine failure if chain jumps timing
Fix: Requires timing chain kit replacement including tensioner, guides, and usually camshaft replacement due to wear from stretched chain. 8-10 hours labor due to rear-engine packaging. Many techs recommend full engine-out service for proper access.
Estimated cost: $2,800-4,500
0.9L TCe Hydraulic Lifter Collapse and Camshaft Wear
Common · high severityTypical onset: 50,000-90,000 mi
Symptoms: Persistent ticking or tapping noise from valve train, Noise increases with engine temperature, Metal shavings in oil during changes, Loss of compression in one or more cylinders
Fix: Often discovered during timing chain work. Requires lifter replacement (all 12) plus camshaft inspection and frequent replacement due to lobe wear. Many owners report repeat failures even after repair. 10-14 hours labor including cylinder head removal for proper access.
Estimated cost: $3,200-5,800
Automated Manual Transmission Oil Cooler Failure
Occasional · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Transmission slipping or jerky shifts, Overheating warning messages, Burnt smell from transmission area, Fluid leaking near rear subframe
Fix: Oil cooler develops pinhole leaks or internal restriction. Requires cooler replacement and full fluid flush. Access is difficult on rear-engine layout. 4-5 hours labor.
Estimated cost: $800-1,400
Transmission Mount Collapse
Common · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Excessive clunking when shifting or accelerating, Vibration transmitted to cabin floor, Visible engine/trans movement when revving in park, Drivetrain feels loose or imprecise
Fix: Rear-engine configuration puts unusual stress on mounts. Main transmission mount fails frequently. Replacement requires supporting drivetrain from below. 2-3 hours labor.
Estimated cost: $400-700
Head Gasket Failure on 0.9L TCe
Occasional · high severityTypical onset: 70,000-120,000 mi
Symptoms: White smoke from exhaust on cold starts, Coolant loss with no visible leaks, Overheating under load, Oil contamination in coolant reservoir or milky oil cap
Fix: Three-cylinder design with aluminum head and block creates thermal stress points. Head gasket replacement requires cylinder head machining in most cases due to warping. Often discovered after neglecting timing chain issues. 10-12 hours labor.
Estimated cost: $2,500-4,200
Harmonic Balancer Deterioration
Occasional · medium severityTypical onset: 80,000-130,000 mi
Symptoms: Vibration at idle and low RPM, Squealing or chirping from accessory belt area, Visible wobble on crankshaft pulley, Alternator or A/C charging issues from belt misalignment
Fix: Rubber damper separates from hub due to heat cycling in rear-engine bay. Replacement straightforward but timing chain replacement is often recommended simultaneously due to similar access requirements. 3-4 hours labor standalone, add 1 hour if bundling with timing work.
Estimated cost: $500-900
Hard pass on the 0.9L turbo due to catastrophic timing chain and lifter issues; the 1.0L SCe is acceptable for city use but parts availability outside Europe is challenging and any major repair approaches the car's resale value.
