2014 SMART FORTWO

Typical onset: 60,000-100,000 mi

Symptoms: Hard or delayed shifts, especially 1st to 2nd, Clunking or jerking during acceleration, Transmission warning light or 'Visit Workshop' message, Complete loss of power delivery, won't move, Burning clutch smell in stop-and-go traffic

Fix: The AMT uses a single dry clutch actuated by an electric motor; clutch actuator failures and worn clutches are endemic. Many units need full transmission rebuild or replacement by 80k miles. Clutch actuator alone: 4-6 hours labor. Full rebuild or reman unit: 8-12 hours plus transmission removal complexity. Used transmissions are common but risky—many are already worn.

Estimated cost: $2,500-5,500

Symptoms: One or both headlights completely out, Flickering or intermittent operation, Moisture or condensation inside lens, Low beam works but high beam doesn't, or vice versa, Bulb replacement doesn't fix the issue

Fix: The sealed headlight assemblies have internal ballast or LED driver failures that aren't serviceable separately—entire unit replacement required. Moisture intrusion accelerates failure. Each assembly runs $400-800 for aftermarket, $1,200+ OEM. Labor is only 1-2 hours per side, but parts kill you. Both sides often fail within months of each other.

Estimated cost: $900-2,400

Symptoms: Random electrical issues: no start, no crank, or intermittent power loss, Multiple warning lights appearing simultaneously, Climate control or power windows acting erratically, Corroded or melted fuse terminals visible on inspection, Issues worse in humid climates or after rain

Fix: The SAM module (fuse/relay box) under the hood is poorly sealed and collects moisture. Corrosion causes cross-circuit faults and melted terminals. Cleaning sometimes works short-term, but most need a replacement SAM unit plus diagnosing which circuits were damaged. 3-5 hours labor for replacement and reprogramming, but diagnostic time can double that if chasing phantom problems first.

Estimated cost: $800-1,800

Typical onset: 50,000-90,000 mi

Symptoms: Transmission fluid spots under car (usually pink/red), Visible oil cooler line leaking at fittings, Rough shifting that improves after fluid top-off, Clunking from transmission mount area over bumps, Excessive engine/trans movement visible in engine bay

Fix: The AMT oil cooler lines and their quick-disconnect fittings crack or leak; the rubber transmission mount also fails early due to the constant jerking motion of the AMT. Oil cooler lines: 2-3 hours. Transmission mount: 2-4 hours (requires supporting transmission). Often done together since access overlaps.

Estimated cost: $400-1,200

Typical onset: 80,000-120,000 mi

Symptoms: Rough idle or misfires at cold start, Loss of power or poor throttle response, Check engine light with misfire or lean codes, Excessive oil consumption between changes, Turbo lag or boost issues

Fix: Direct-injection engines suffer carbon buildup on intake valves. Also, the tiny 900cc three-cylinder runs hot and can develop valve sealing issues or minor head gasket seepage. Walnut blasting the valves: 4-6 hours. If head removal needed for valve work or gasket: 10-14 hours on this cramped platform. Head gasket jobs are rare but painful due to tight engine bay.

Estimated cost: $600-3,200

Typical onset: 60,000-100,000 mi

Symptoms: Pulling to one side during braking, One front wheel noticeably hotter after driving, Premature brake pad wear on one side, Grinding or dragging noise from front wheel, Reduced fuel economy due to constant drag

Fix: The single-piston front calipers seize due to corrosion or dried-out slide pins, especially in salt-belt states. Rebuilding is possible but replacement is faster and more reliable given the low cost of reman units. 1.5-2 hours per side for caliper replacement, includes bleeding. If both sides done preventively: 3 hours total.

Estimated cost: $300-700
