The 2018 Fiat Tipo PL is a budget-friendly European compact that suffers from serious valvetrain issues on the 1.3 MultiJet diesel and transmission cooling problems across all variants. The 1.0 FireFly turbo shows premature timing chain wear, while the 1.6 diesel is relatively more robust but still plagued by DPF and EGR headaches typical of emissions-era diesels.
1.3 MultiJet Diesel Hydraulic Lifter Failure
Common · high severityTypical onset: 40,000-80,000 mi
Symptoms: Loud ticking or tapping at idle that worsens when cold, Loss of power and rough running as camshaft lobes wear, Metal shavings in oil, catastrophic failure if ignored
Fix: Full cylinder head removal, lifter replacement (all 8), camshaft inspection or replacement if worn. Requires head resurfacing in most cases. 12-16 labor hours due to tight engine bay access and head work.
Estimated cost: $3,200-5,800
Transmission Oil Cooler Line and Mount Failure
Common · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Transmission fluid leaking onto subframe or ground, Harsh shifting or slipping when transmission overheats, Clunking from transmission area over bumps (failed mount)
Fix: Oil cooler lines crack at fittings; transmission mount tears from vibration. Cooler lines require 2-3 hours, mount replacement another 1.5-2 hours. Often done together as preventive measure.
Estimated cost: $450-950
1.0 FireFly Turbo Timing Chain Premature Stretch
Occasional · high severityTypical onset: 60,000-100,000 mi
Symptoms: Rattling on cold start that lasts 3-5 seconds, Check engine light with cam/crank correlation codes (P0016/P0017), Poor fuel economy and hesitation under load
Fix: Three-cylinder timing chain tensioner design is marginal. Requires chain, tensioner, guides, and variable cam phaser replacement. Front engine work with special locking tools. 8-10 labor hours.
Estimated cost: $1,800-2,900
1.6 MultiJet DPF and EGR System Clogging
Common · medium severityTypical onset: 70,000-120,000 mi
Symptoms: Limp mode and reduced power warnings, Excessive black smoke on acceleration, Frequent regeneration attempts, poor fuel economy, Engine management light with P2002/P0401 codes
Fix: DPF cleaning or replacement plus EGR valve/cooler service. Short-trip driving accelerates buildup. DPF replacement 3-4 hours, EGR cleaning 2-3 hours. Many owners opt for preventive EGR delete where legal.
Estimated cost: $1,200-3,500
Harmonic Balancer Deterioration (All Engines)
Occasional · medium severityTypical onset: 80,000-130,000 mi
Symptoms: Vibration at idle that increases with RPM, Serpentine belt tracking off-center or shredding, Visible wobble on crankshaft pulley when running
Fix: Rubber ring separates from hub due to heat cycling. Requires crankshaft holder tool and impact work. 2-3 hours on 1.0L turbo (tight access), 1.5-2 hours on diesels.
Estimated cost: $380-650
Fuel Filter Housing Cracking (Diesel Models)
Occasional · medium severitySymptoms: Hard starting or no-start when cold, Air in fuel system, requires repeated priming, Visible fuel weeping from filter housing base
Fix: Plastic housing develops hairline cracks from vibration. Filter changes every 20,000 mi recommended, housing replacement when cracked. 1-2 hours including system bleeding and priming.
Estimated cost: $280-480
Buy the 1.6 diesel if you drive highways regularly, avoid the 1.3 diesel entirely, and budget $2,000 for deferred maintenance on any used example—these are cheap to buy but not cheap to keep running.
