What stands out
Of the 5 model years of Volvo XC90 we track for engine problems, this one carries the most owner complaints on file — 58.
Owners have filed 58 engine complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The 2005 XC90 V8 (Yamaha-built engines, serial numbers up to approximately 6833) has a dominant failure pattern: unlubricated counter-balance shaft bearings in a sealed engine cavity accumulate moisture and rust, then catastrophically fail between 55,000 and 115,000 miles. Owners describe sudden loud ticking, grinding, or knocking from inside the block with no check-engine warning—exactly the symptom pattern you'd expect from a bearing collapsing. Engine removal is mandatory for repair ($3,000–$5,000 for bearing replacement, $14,000–$16,850 for full replacement). Volvo issued a Technical Service Bulletin directing dealers to drill a drainage hole in the block after recognizing the defect, proving awareness. The company denies recall and refuses to cover repairs outside the 4-year/50,000-mile warranty, despite acknowledging the problem internally.
Secondary issues include water intrusion into the ECM causing complete electrical shutdown while driving (power steering, braking, lights all lost at highway speed) and transmission failures with slipping or sudden loss of power. Check-engine lights persist despite multiple dealer service attempts in some cases. One owner had the car towed from the middle of an intersection after counter-balance failure; another experienced ECM shutdown in 110-degree heat with a one-year-old child aboard. Dealers won't service warranty claims after the coverage period expires, regardless of mileage or severity.
Failure modes owners describe
Counter-balance shaft bearing failure
Non-lubricated bearing in sealed cavity of V8 engine block rusts due to moisture intrusion, causing catastrophic engine damage. Occurs in early 2005 XC90 V8s (engine serial numbers up to ~6833, produced by Yamaha). Bearing deteriorates silently with no check-engine warning, then breaks apart. Damage ranges from bearing replacement (with engine removal) to complete engine failure requiring full replacement.
When: 55,000–126,000 miles; typically 55k–115k range. Can occur regardless of mileage once moisture penetrates; some owners report failure within 2 years of light use.
Symptoms owners cite: Loud ticking, clattering, knocking, grinding, or popping noise from engine block (described as marbles rattling or ball bearings rolling); Engine vibration felt in floorboard; Sudden loss of engine power during driving; Engine stalls without warning; Rough engine idle; No check-engine light in most cases
Repairs/costs cited: Repair: Replace counter-balance shaft and/or bearing; requires full engine removal and block opening (~30 hours labor). Cost $3,000–$5,000 for bearing/shaft replacement. Alternative: Full engine replacement, $14,000–$16,850. Parts (bearings, shaft) alone $1,200–$2,000. Volvo issued TSB directing dealers to drill weeping hole in engine block to drain moisture; hole-drilling is part of repair. One owner reported Volvo paid $1,500 of ~$3,800 total repair cost.
Recalls/TSBs owners mention: Volvo issued TSB (Technical Service Bulletin) for early 2005 V8 engines directing dealers to drill weeping hole in engine block to drain moisture from bearing cavity. Volvo also issued TSB advising against engine washing to prevent moisture buildup (communicated to dealers, not consumers). Design change implemented mid-production (engine #6833+) added weeping hole from factory. Volvo has refused recalls; company states issue is 'not problematic enough' to warrant recall and evaluates complaints case-by-case. Volvo North America denies coverage after warranty expires (4 years/50,000 miles), despite acknowledging the issue. One owner (complaint #25) reported Volvo compensated ~$1,500 of $3,800 repair. One transmission-replacement case (#27) was covered at no cost by dealer after software upgrade failure.
Electrical system failure / ECM malfunction
Complete electrical shutdown or partial loss of critical electrical functions (power steering, braking, headlights, interior lights, radio, blinkers) while driving, sometimes progressing to engine stall. Associated with water intrusion into Engine Control Module (ECM) housing, particularly after rain or high-humidity conditions. Volvo redesigned ECM cover to address water intrusion but no recall issued.
When: Intermittent electrical failures reported; complete failure examples at ~61,000 miles. Failures correlate with rain/humid weather.
Symptoms owners cite: Radio cuts out; All dashboard lights and warning lights illuminate (brake failure, power overload, limp mode); Loss of A/C; Loss of power steering; Intermittent or loss of braking ability; Loss of headlights and interior lighting; Loss of blinkers and windshield wipers; Engine stall or intermittent engine power loss; Vehicle unable to restart; Multiple diagnostic trouble codes present
Repairs/costs cited: ECM replacement cost $1,500–$3,000. Water in ECM confirmed by dealer inspection. Battery replacement may also be required. Dealers reset ECM (clear codes) without owner authorization in at least one case.
Recalls/TSBs owners mention: Volvo redesigned ECM cover to prevent water intrusion but has not issued a recall. Volvo North America directed dealers to reset vehicles (clear error codes) when failures occur, sometimes without owner permission. No documented manufacturer assistance with repair costs.
Engine misfire and check-engine light (persistent)
Check-engine light illuminates repeatedly or persistently, often with diagnostic codes indicating misfires in specific cylinders (e.g., cylinders 6 & 8). Multiple dealer service attempts (spark plug replacement, fuel filter change, fuel treatment) fail to resolve issue. Problem may relate to fuel system or ignition, but root cause remains unidentified after repeated visits.
When: ~2 months after purchase (one case); 1+ year duration in another case. Occurs regardless of regular maintenance.
Symptoms owners cite: Check-engine light on; Engine misfire codes (cylinders 6 & 8 cited); Car breaks down, requiring towing (highway stall possible)
Codes mentioned: Misfire codes (specific cylinder numbers not always listed)
Repairs/costs cited: Spark plug replacement $500; fuel filter and fuel treatment $154. Multiple repeat repairs without resolution. One owner spent over $1,000 in repairs and car rental within 2 months of purchase.
Recalls/TSBs owners mention: None documented. Volvo dealership initially blamed gas cap, then performed multiple diagnostic tests and repairs without identifying root cause.
Transmission failure / slipping
Transmission slips or fails in low gears and during acceleration, or transmission loses power entirely. In one case, transmission failed 3 weeks after a software upgrade. In another, shredded metal reached radiator and coolant system requiring additional repairs.
When: 64,000–79,000 miles. Can occur after software upgrade.
Symptoms owners cite: Transmission slips in low gears; Loss of power during acceleration; Unexpected slowing at highway speeds; Transmission service light illuminates
Repairs/costs cited: Transmission replacement cost $5,300–$6,700 (including coolant system damage repair). Transmission on back order 1–2 months. In one case, dealership replaced transmission and other damaged parts at no cost after failure.
Recalls/TSBs owners mention: Volvo acknowledged the issue as 'a common problem' in the 2005 model per one owner's contact with tech support, but declined to issue recall. One dealer (Don Beyer Volvo) covered full transmission replacement and related part repairs at no cost after complete failure.
Engine stall / loss of power while driving
Engine suddenly stalls or loses power while driving at various speeds (30–110 mph), without warning. Vehicle may restart after a few moments or require towing. No consistent diagnostic code pattern reported. Causes include timing chain breakage (at least one case) and possible ECM or fuel system issues.
When: Failure mileages range 75,000–110,000+ miles.
Symptoms owners cite: Engine suddenly stalls at speed; Vehicle loses all power; Check-engine light may illuminate; Loss of power steering and braking control during stall
Repairs/costs cited: Timing chain failure requiring engine replacement ($14,000+) in one case. Other cases not repaired or repair cost not documented.
Recalls/TSBs owners mention: Volvo refused responsibility in one case (timing chain failure at 75,000 miles) stating vehicle was not serviced at a dealer, despite regular independent maintenance.
Timing chain failure
Timing chain breaks, locking up engine and causing catastrophic engine failure. At least one case documented at ~75,000 miles.
When: ~75,000 miles
Symptoms owners cite: Engine locks up; Loud noise from engine; Sudden loss of power and inability to restart
Repairs/costs cited: Engine replacement required; estimated cost $14,000+.
Recalls/TSBs owners mention: Volvo denied responsibility, citing lack of dealer service history.
