Recalls
Deferred Failure RiskComponents and defects approaching or past their known service milestones
38/100
Monitor Deferred Risk
6 component(s) approaching service intervals within the next 20,000 miles. Factor routine maintenance costs into your ownership budget.
⚠No odometer data on record. Mileage is estimated at ~72,000 mi based on average annual driving. Items marked EST. OVERDUE may already be due — verify service history with the seller. Items marked OVERDUE are confirmed past-due based on vehicle age alone.
MONITORCriticalTiming Chain Tensioner
Service interval: 120,000 mi · Est. ~72,000 mi (no odometer on record)
Schedule Timing Chain Tensioner service before 120,000 mi
Worn chain tensioners cause timing chain skip or snap — common on GM 5.3L/6.2L, Ford EcoBoost, VW/Audi EA888, BMW N47/N63. Listen for cold-start rattles.
MONITORCriticalWater Pump
Service interval: 100,000 mi · Est. ~72,000 mi (no odometer on record)
Schedule Water Pump service before 100,000 mi
Water pump failure causes rapid overheating. If the engine overheats even once, head gasket damage is likely — turning a $400 part into a $3,000+ repair.
EST. OVERDUEHighTransmission Fluid / Service
Service interval: 5 yr · Vehicle age: 6 yr · Past due by age
Service Transmission Fluid / Service immediately — already past the 60,000 mi / 5 yr interval
Degraded transmission fluid destroys clutch packs and solenoids. CVT transmissions are especially sensitive — neglected fluid can result in a $4,000–$8,000 replacement.
EST. OVERDUEHighCoolant Flush
Service interval: 5 yr · Vehicle age: 6 yr · Past due by age
Service Coolant Flush immediately — already past the 100,000 mi / 5 yr interval
Degraded coolant loses corrosion inhibitors and attacks aluminum engine components. Can cause head gasket failure and water pump corrosion.
MONITORModerateSpark Plugs (iridium/platinum)
Service interval: 100,000 mi · Est. ~72,000 mi (no odometer on record)
Schedule Spark Plugs (iridium/platinum) service before 100,000 mi
Worn spark plugs cause misfires that can foul and crack catalytic converters. A $150 tune-up can prevent a $1,200 catalytic converter replacement.
MONITORModerateFuel Injectors
Service interval: 120,000 mi · Est. ~72,000 mi (no odometer on record)
Schedule Fuel Injectors service before 120,000 mi
Dirty or failing injectors cause rough idle, reduced fuel economy, and increased emissions. Cleaning costs $100–$200; replacement $800–$1,600.
