2017 PEUGEOT 3008

Typical onset: 40,000-80,000 mi

Symptoms: rattling on cold start, metal particles in oil, check engine light, sudden loss of power, catastrophic engine failure if belt disintegrates

Fix: Belt runs in oil and degrades, shedding debris that clogs oil pump and starves engine. Requires full timing system replacement (belt, tensioner, water pump) plus oil system flush; if caught late, often needs full engine rebuild or replacement. 8-12 hours labor for preventive replacement, 25-40 hours for engine rebuild.

Estimated cost: $1,800-3,500 preventive, $6,000-10,000 if engine damaged

Typical onset: 60,000-100,000 mi

Symptoms: harsh shifting between 2nd-3rd gears, shuddering during acceleration, delayed engagement, transmission slipping, metallic grinding noise

Fix: Aisin EAT6 unit suffers from torque converter issues and valve body failures. Fluid changes help but don't cure design flaws. Most need full transmission rebuild or replacement unit. 12-16 hours labor for R&R and rebuild.

Estimated cost: $3,500-6,500

Typical onset: 50,000-90,000 mi

Symptoms: anti-pollution fault warning, limp mode activation, AdBlue quality error messages, excessive DPF regeneration cycles, poor fuel economy

Fix: DPF clogs on short-trip use; AdBlue injector and heater fail regularly. Forced regens help temporarily but many need DPF replacement and/or AdBlue injector. DPF delete not legal in most markets. 4-6 hours for DPF replacement, 2-3 hours for AdBlue components.

Estimated cost: $800-2,200

Typical onset: 60,000-100,000 mi

Symptoms: clunking when shifting or accelerating, excessive engine movement visible from engine bay, vibration through cabin at idle, gear lever shudder

Fix: Hydraulic mounts fail early, especially on PureTech and diesel models with torque spikes. Usually need both transmission mount and upper engine mount replaced together. 2-3 hours labor for both.

Estimated cost: $400-800

Typical onset: 70,000-110,000 mi

Symptoms: visible oil leak from turbo area, burning oil smell, blue smoke on acceleration, low oil level warnings, turbo whistle or whine changing pitch

Fix: Oil feed and return lines crack or connections loosen, starving turbo of lubrication. Catch early before turbo damage occurs. Requires turbo removal for proper seal replacement. 4-5 hours labor.

Estimated cost: $600-1,200

Typical onset: 80,000-120,000 mi

Symptoms: white smoke from exhaust, coolant loss with no visible leak, overheating, oil contamination in coolant reservoir, rough idle and misfires

Fix: Three-cylinder design runs hot; head gasket fails between cylinders or into coolant passages. Often discovered after wet belt failure damages block. Head may need resurfacing. 10-14 hours labor including head removal and reinstallation.

Estimated cost: $2,200-3,800

Symptoms: water pooling in footwells, headliner staining, musty smell in cabin, water dripping from A-pillar trim, electrical gremlins from wet BCM

Fix: Large panoramic roof has four drains that clog with debris. Water backs up and enters cabin, often soaking front BCM under driver carpet. Requires drain clearing and sometimes drain tube replacement. 1-2 hours labor plus BCM repair if damaged.

Estimated cost: $150-400, $800-1,500 if BCM damaged
