The 2019 Fiat 500 Abarth with the 1.4L MultiAir turbo is a fun, high-strung hot hatch that pushes a small engine hard. While relatively new, this platform has a troubling pattern of catastrophic engine failures related to oil starvation, piston ring issues, and connecting rod bearing wear—often appearing surprisingly early in the vehicle's life.
Connecting Rod Bearing Failure / Spun Bearings
Occasional · high severityTypical onset: 40,000-80,000 mi
Symptoms: Loud knocking or rattling from bottom end, especially on cold start, Sudden loss of oil pressure warning, Metal shavings in oil during changes, Engine may seize or throw a rod if driven after symptoms appear
Fix: This is a complete bottom-end rebuild or short block replacement. Expect 18-25 hours of labor to drop the engine, disassemble, inspect crank journals, replace bearings, pistons, rings, and reassemble. Often cheaper to source a used engine or short block than rebuild. Root cause is often aggressive driving + extended oil change intervals on a high-stress turbo motor.
Estimated cost: $4,500-8,000
Piston Ring Failure / Oil Consumption
Common · high severityTypical onset: 50,000-90,000 mi
Symptoms: Burning 1+ quart of oil every 1,000-1,500 miles, Blue smoke from exhaust on startup or under load, Fouled spark plugs (oil-fouled, misfires), Loss of power and boost pressure as rings lose seal
Fix: Requires engine teardown to replace piston rings or full piston assemblies. Head removal, cylinder honing if needed, new rings, gaskets. Budget 20-28 hours. Many owners opt for short block replacement instead of rebuilding due to labor overlap. The MultiAir system is hard on rings due to high cylinder pressures and heat.
Estimated cost: $3,800-7,500
Transmission Oil Cooler Failure
Occasional · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Transmission overheating warnings on dash, Slipping or delayed shifts, especially in hot weather or traffic, Transmission fluid leaking from cooler lines, Burnt transmission fluid smell
Fix: Replace transmission oil cooler and flush/replace ATF. Cooler is integrated into radiator assembly on some variants; on others it's a separate unit. Labor is 3-5 hours depending on configuration. Failure often tied to hard driving or towing (which this car should never do). Caught early, transmission itself survives.
Estimated cost: $600-1,200
Transmission Mount Failure
Common · low severityTypical onset: 50,000-80,000 mi
Symptoms: Excessive drivetrain clunk on hard shifts or throttle lift, Vibration felt through shifter and cabin at idle, Visible movement of transmission when rocking car in gear, Increased NVH (noise, vibration, harshness)
Fix: Replace worn transmission mount(s). The Abarth's aggressive tune and sporty driving exacerbate mount wear. Front lower mount is most common. Labor is 1.5-2.5 hours. Straightforward job, but requires supporting the transmission. Aftermarket polyurethane mounts available for those wanting firmer feel.
Estimated cost: $250-500
Turbocharger Wastegate Actuator Sticking
Occasional · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Check engine light with overboost or underboost codes (P0234, P0299), Loss of power or boost inconsistency, Turbo whistle or flutter sounds change character, Limp mode activation under load
Fix: Wastegate actuator arm seizes or linkage wears, preventing proper boost control. Sometimes cleanable/lubricated, but typically requires turbo removal and actuator replacement or turbo rebuild. Labor 5-8 hours to remove turbo, replace actuator, reinstall, and road test. Carbon buildup from direct injection contributes.
Estimated cost: $800-1,800
MultiAir Solenoid Failure
Occasional · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Rough idle, misfires, or stalling, Check engine light with cam/crank correlation codes or intake valve timing codes, Poor fuel economy and lack of power, Ticking noise from valve cover area
Fix: The MultiAir electro-hydraulic valve actuation system uses solenoids that fail from contamination or wear. Replacement requires valve cover removal, draining oil, and replacing solenoid pack. 3-5 hours labor. Must use clean oil and OEM or high-quality replacement parts. Dirty oil accelerates failure.
Estimated cost: $600-1,200
Buy only with documented frequent oil changes and low-stress driving history—too many have grenaded engines before 80k miles due to oil starvation and bearing failures for a car this new.
