2022 DS AUTOMOBILES DS 7

Typical onset: 30,000-70,000 mi

Symptoms: rattling on cold start especially first 30 seconds, metal particles in oil, check engine light with cam/crank correlation codes, sudden loss of power and engine death if belt fails

Fix: Complete timing belt replacement requires 6-8 hours labor, often discovers oil pump damage and camshaft scoring once opened up. Many techs now recommend preemptive replacement at 60k regardless of service schedule. Engine rebuild common if belt disintegrates (adds 25-35 hours).

Estimated cost: $1,800-3,200 preventive / $8,000-14,000 post-failure rebuild

Typical onset: 40,000-80,000 mi

Symptoms: rough idle and hesitation on acceleration, misfires especially on cold starts, reduced fuel economy, P0300-P0304 misfire codes

Fix: Walnut blasting required, 4-5 hours with intake manifold removal. Direct injection means no fuel washing valves. Catch can installation adds 2 hours but helps long-term. May need new lifters if severely carboned (add 8 hours).

Estimated cost: $800-1,400 cleaning / $2,200-3,500 with lifter replacement

Typical onset: 50,000-90,000 mi

Symptoms: harsh downshifts or hesitation between 2nd-3rd gear, transmission shudder at low speeds, limp mode activation, check transmission warning on display

Fix: Aisin EAT8 mechatronic unit replacement requires 8-10 hours, includes new transmission fluid and filter. Early cases sometimes resolved with software update and fluid change (3 hours), but mechanical failure needs full unit. Transmission mount failure accelerates this issue.

Estimated cost: $600-900 fluid/mount / $3,500-5,800 mechatronic replacement

Typical onset: 25,000-60,000 mi

Symptoms: reduced EV range suddenly dropping 30-50%, battery cooling fan running constantly, hybrid system fault warnings, refusal to charge or charge very slowly

Fix: Cooling system issues require battery pack inspection (4 hours diagnostic). Coolant leaks into battery tray demand pack removal and seal replacement (12-15 hours). Temperature sensor failures cheaper (3-4 hours) but pack issues expensive. Some battery module replacements covered under 8-year warranty.

Estimated cost: $800-1,500 sensors/software / $6,000-9,000 cooling system repair

Typical onset: 60,000-100,000 mi

Symptoms: loss of boost pressure and sluggish acceleration, overboost codes P0234, whistling or fluttering noise under load, check engine light with reduced power mode

Fix: Wastegate actuator replacement on 1.6 Turbo requires turbo removal, 5-6 hours labor. Often discovers shaft carbon buildup requiring full turbo replacement (same labor). Diesel BlueHDi less prone but not immune.

Estimated cost: $900-1,400 actuator only / $2,200-3,800 turbo replacement

Typical onset: 40,000-80,000 mi

Symptoms: suspension warning light, vehicle sagging on one corner especially overnight, compressor running excessively, rough ride quality loss

Fix: Air strut replacement 3-4 hours per corner, compressor replacement adds 4-5 hours. Leaks often start at strut seals. System can default to conventional mode but ride quality suffers significantly. Parts expensive due to DS-specific components.

Estimated cost: $1,800-2,800 per strut / $2,500-3,800 compressor
