2021 PEUGEOT 2008

Typical onset: 40,000-80,000 mi

Symptoms: metallic rattling at cold start, check engine light with cam/crank correlation codes, oil contamination with belt material, sudden loss of power or no-start

Fix: The wet-belt design runs in engine oil and deteriorates prematurely, shedding debris that clogs oil passages and can destroy the engine. Requires complete timing system replacement including belt, tensioners, water pump, and thorough oil system flush. 8-12 hours labor. PSA issued extended warranty coverage in some markets but many 2021s fall outside coverage windows.

Estimated cost: $2,800-4,500

Typical onset: 30,000-60,000 mi

Symptoms: excessive vibration at idle, clunking when shifting from Park to Drive, harsh engagement under acceleration, visible engine movement in bay

Fix: Hydraulic transmission mount and upper engine mount fail early due to inadequate design for the turbo engine's torque. Transmission mount alone is 2-3 hours, but typically need to replace multiple mounts simultaneously. OEM parts required for proper fitment.

Estimated cost: $800-1,400

Typical onset: 50,000-80,000 mi

Symptoms: clunking over bumps, wandering steering feel, uneven tire wear on inside edges, pulling during braking

Fix: Front lower control arm bushings are rubber-bonded and non-serviceable separately—requires complete arm replacement. Both sides typically fail within 5,000 miles of each other. Alignment mandatory after replacement. 3-4 hours labor for both sides with alignment.

Estimated cost: $900-1,500

Typical onset: 60,000-100,000 mi

Symptoms: rear axle steering feel over bumps, thumping from rear on rough roads, abnormal rear tire wear patterns

Fix: Rear trailing arm bushings wear prematurely on rough roads or with heavy loading. Bushings can be pressed out and replaced separately (2 hours per side) or swap complete arms (easier alignment, 2.5 hours both sides). Aftermarket polyurethane options available but create more NVH.

Estimated cost: $500-900

Typical onset: 40,000-70,000 mi

Symptoms: shudder during 2-3 or 3-4 upshift, delayed engagement from stop, harsh downshifts, transmission overheating warnings

Fix: The Aisin EAT8 automatic develops clutch shudder and requires early fluid changes despite 'lifetime fill' claims. Some cases need mechatronic unit software updates. Fluid and filter service is 2 hours; mechatronic reflash adds 1 hour. Severe cases need clutch pack replacement (transmission-out, 12+ hours).

Estimated cost: $400-700 for service, $3,500-5,000 for clutch packs

Typical onset: 50,000-90,000 mi

Symptoms: transmission fluid on inner CV boot area, drips on ground after parking, low fluid level on dipstick, burning smell if fluid contacts exhaust

Fix: Front differential output seals leak on higher-mileage units, often accelerated by worn CV axles causing seal wear. Requires axle removal and seal replacement, 2-3 hours per side. Good practice to replace CV axles simultaneously if they have any play.

Estimated cost: $600-1,100 including both seals and axles

Symptoms: check engine light with DPF codes, loss of power in limp mode, excessive fuel consumption, diesel smell in cabin, DPF warning light flashing

Fix: Short-trip driving prevents proper DPF regeneration cycles, leading to clogged filters. Requires forced regeneration (1 hour), DPF cleaning ($500-800), or replacement ($1,800-2,500 parts alone, 4-5 hours labor). PSA's AdBlue system also develops sensor and heater faults adding complexity.

Estimated cost: $200-3,500 depending on severity
