2017 FIAT FIORINO

Typical onset: 70,000-110,000 mi

Symptoms: loud ticking/tapping at idle that worsens when warm, rough idle and loss of power, Check Engine Light with misfire codes P0300-P0304, metallic rattling on cold start

Fix: The Fire Evo hydraulic lifters collapse due to oil sludge or wear, scoring the camshaft lobes. Requires cylinder head removal, lifter replacement (all 16), cam inspection/replacement if damaged, and valve adjustment. 8-12 labor hours depending on cam condition. If cam is scored, you're looking at camshaft R&R adding 3-4 hours.

Estimated cost: $1,800-3,500

Typical onset: 80,000-130,000 mi

Symptoms: coolant loss with no visible leaks, white smoke from exhaust, overheating under load, milky oil on dipstick or cap, rough running and misfires

Fix: Multi-layer steel head gasket fails between cylinders 2-3 or into coolant passages. Head must come off, be resurfaced (almost always warped .003-.008 inches), new gasket, ARP studs recommended. Timing belt should be replaced during this job. 10-14 labor hours including machine shop time.

Estimated cost: $2,200-3,800

Typical onset: 60,000-100,000 mi

Symptoms: severe clunking when shifting or accelerating, excessive engine movement visible from engine bay, vibration at idle in gear, difficulty engaging first or reverse

Fix: The lower transmission mount (dogbone) and right-side engine mount fail due to fluid leakage and rubber deterioration. Both should be replaced together. 2-3 labor hours with proper support tooling.

Estimated cost: $350-650

Typical onset: 90,000-140,000 mi

Symptoms: severe belt squeal that comes and goes, visible wobble of crank pulley at idle, serpentine belt repeatedly throwing or shredding, rough vibration that increases with RPM

Fix: The rubber damper ring separates from the hub, causing pulley wobble and potential timing belt damage if debris enters covers. Requires crank pulley removal with proper holding tool, timing belt inspection. 3-4 labor hours, timing belt replacement adds 2-3 hours if contaminated.

Estimated cost: $450-900

Typical onset: 70,000-120,000 mi

Symptoms: transmission fluid spots under vehicle, burnt transmission smell, slipping or delayed engagement when cold, low fluid level on dipstick

Fix: Steel cooler lines rust through at bends or fittings, particularly in salt-belt regions. Lines should be replaced in pairs, system flushed, fluid refilled. 2-3 labor hours depending on access.

Estimated cost: $400-750

Symptoms: hard starting after sitting overnight, loss of power under acceleration, rough idle and stumbling, P0171/P0174 lean codes

Fix: Ethanol fuel attracts moisture causing corrosion debris in tank that clogs the in-tank filter screen and external filter. Both should be serviced—tank screen requires tank drop. External filter is 0.5 hours, tank screen adds 2-3 hours. Common on vehicles using E85 regularly.

Estimated cost: $180-450
