2022 PEUGEOT 5008

Typical onset: 40,000-80,000 mi

Symptoms: Metallic rattling on cold start that disappears when warm, Oil contamination with white sludge or particulates in oil cap, Check engine light with timing correlation codes (P0016, P0017), Catastrophic engine failure if belt disintegrates—sudden loss of power, loud grinding

Fix: Requires full timing system replacement including wet belt, oil pump chain, tensioners, and often a full flush of contaminated oil system. If belt has failed completely, expect bent valves and possible piston damage requiring cylinder head work or complete engine rebuild. Preventive replacement: 6-8 hours labor. Post-failure engine rebuild: 20-30 hours.

Estimated cost: $1,800-3,200 preventive; $6,000-9,500 post-failure rebuild

Typical onset: 30,000-70,000 mi

Symptoms: Harsh shifts or delayed engagement from Park to Drive, Shuddering or jerking during low-speed acceleration (10-30 mph), Transmission slipping into limp mode with warning light, Clunking when shifting between 2nd and 3rd gears

Fix: Often starts with transmission fluid and filter service (3 hours), but persistent cases require mechatronic unit replacement or complete valve body work. Some units need software calibration updates. Transmission removal required for internal repairs: 12-16 hours total.

Estimated cost: $800-1,200 fluid service; $3,500-5,800 mechatronic replacement

Typical onset: 50,000-90,000 mi

Symptoms: Transmission fluid spots under vehicle (red or brown fluid), Excessive engine movement or clunking over bumps, Vibration felt through cabin at idle, Low transmission fluid warnings on dashboard

Fix: Upper transmission mount commonly fails due to engine torque stress on the 3-cylinder. Oil cooler lines crack at crimp points. Mount replacement: 2-3 hours. Cooler line replacement requires dropping subframe on some configurations: 4-5 hours. Often done together.

Estimated cost: $450-800 mount only; $900-1,400 with cooler lines

Typical onset: 60,000-100,000 mi

Symptoms: Check engine light with P2002 (DPF efficiency) or P0400 (EGR flow) codes, Loss of power and reduced acceleration, especially uphill, Excessive black smoke on hard acceleration, Rough idle and increased fuel consumption

Fix: Short-trip driving accelerates DPF clogging. Requires DPF cleaning or replacement (5-7 hours) and EGR valve/cooler service (3-4 hours). AdBlue system issues can compound problems. Some cases need forced regeneration cycles first to confirm hardware failure.

Estimated cost: $1,200-2,400 DPF clean/replacement; $700-1,100 EGR service

Typical onset: 60,000-110,000 mi

Symptoms: White smoke from exhaust (coolant burning), Persistent coolant loss with no visible external leaks, Overheating under load or in traffic, Oil cap shows milky residue (coolant mixing with oil), Bubbles in coolant reservoir when engine running

Fix: Often linked to wet-belt oil contamination causing localized overheating. Requires cylinder head removal, resurfacing, and complete gasket set. Head studs should be replaced. If head is warped beyond spec, replacement needed. 14-18 hours labor including coolant system flush and pressure test.

Estimated cost: $2,800-4,500 gasket replacement; $4,500-6,200 with head replacement

Typical onset: 70,000-120,000 mi

Symptoms: Oil pooling under engine bay (front seal) or between engine and transmission (rear), Oil residue visible on lower engine block or transmission bell housing, Burning oil smell after highway driving, Gradual oil consumption requiring top-ups between changes

Fix: Front main seal: 4-5 hours (timing cover removal on PureTech engines). Rear main seal: 8-10 hours (transmission must come out). Often discovered during timing belt or clutch jobs. Not urgent unless leak is severe, but transmission removal cost makes it worth doing proactively during other trans-out work.

Estimated cost: $600-950 front seal; $1,400-2,100 rear seal
