The 2025 Peugeot 2008 shares the CMP platform with several PSA/Stellantis models and is generally reliable, but the 1.2L PureTech three-cylinder has known wet-belt timing issues, transmission mounts wear prematurely, and the EAT8 automatic transmission can develop fluid cooler leaks that lead to expensive failures if ignored.
1.2L PureTech Wet Timing Belt Failure
Common · high severityTypical onset: 40,000-80,000 mi
Symptoms: Metallic rattling on cold start that disappears after warm-up, Oil contamination with belt debris visible on dipstick, Check engine light with cam/crank correlation codes, Catastrophic engine failure if belt disintegrates
Fix: Timing belt runs in engine oil and degrades, shedding material into lubrication system. Requires timing belt replacement, oil system flush, new oil pump, and often cam phasers. Prevention: 3-year/30K mile belt changes regardless of official interval. 8-12 hours labor.
Estimated cost: $2,800-4,500
EAT8 Transmission Oil Cooler and Line Leaks
Occasional · high severityTypical onset: 50,000-90,000 mi
Symptoms: Transmission fluid spots under vehicle near front-center, Burnt smell from transmission area, Harsh shifting or delayed engagement when fluid is low, Transmission overheat warnings on instrument cluster
Fix: Cooler lines corrode at crimp connections or cooler itself develops pinhole leaks. If caught early, replace lines and cooler (4-6 hours). If driven low on fluid, internal clutch damage requires transmission replacement or rebuild (12-16 hours). Critical to check fluid level every oil change on these.
Estimated cost: $800-1,400 for cooler/lines, $4,500-6,500 for transmission rebuild
Engine and Transmission Mount Failure
Common · medium severityTypical onset: 35,000-70,000 mi
Symptoms: Clunking when shifting from Park to Drive or Reverse, Excessive engine rocking visible from outside during acceleration, Vibration felt through steering wheel at idle, Transmission tunnel vibration during gear changes
Fix: Upper engine mount and left transmission mount use hydraulic design that fails prematurely. Rubber separates from internal components. Replace both mounts as a pair; doing one leads to accelerated failure of the other. 2-3 hours labor for the pair.
Estimated cost: $450-750
1.5L BlueHDi Diesel Particulate Filter Clogging
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: DPF warning light illuminated on dash, Loss of power in limp mode, Increased fuel consumption, Frequent regeneration cycles with temperature spikes
Fix: DPF clogs on vehicles driven primarily short trips or city cycles. Requires forced regeneration via diagnostic tool (1 hour) or DPF replacement if substrate is damaged (3-5 hours). Preventive: monthly highway runs at sustained 60+ mph for 30 minutes to allow passive regen.
Estimated cost: $150-300 for forced regen, $1,800-2,800 for DPF replacement
Front Subframe Corrosion and Mounting Point Cracks
Occasional · high severityTypical onset: 70,000-120,000 mi
Symptoms: Clunking over bumps from front suspension, Steering feels vague or wanders on highway, Visible rust perforation on subframe crossmember, Control arm bolts wallowing in subframe holes
Fix: Subframe uses thin-wall steel construction and corrodes in salt-belt environments. Mounting points crack around control arm bushings. Subframe replacement requires full front suspension removal, alignment, and steering system disconnection. 8-10 hours labor. Inspect annually if in rust belt.
Estimated cost: $2,200-3,500
e-2008 Heat Pump and Heater Core Issues
Occasional · medium severitySymptoms: Insufficient cabin heat in winter below 20°F, Coolant smell inside cabin, Fogging windshield with sticky residue, Range loss greater than expected in cold weather
Fix: Heat pump system struggles in extreme cold; heater core can develop leaks where electric coolant heater connects. Heat pump compressor failures require refrigerant recovery and component replacement (6-8 hours). Heater core requires full dash removal (10-14 hours). EV-specific high-voltage safety procedures add complexity.
Estimated cost: $1,800-3,200 for heat pump, $2,500-4,000 for heater core
Buy the e-2008 if you need electric and can handle reduced cold-weather range; avoid the 1.2L PureTech unless you're prepared for expensive timing belt maintenance—the 1.5L diesel is the sweet spot for longevity if you drive highway miles.
