Deferred Failure RiskComponents and defects approaching or past their known service milestones
82/100
Critical Deferred Risk
Critical deferred failure risk — 5 safety-critical or high-cost components are past their service interval. Without immediate attention, repair costs will compound significantly.
⚠No odometer data on record. Mileage is estimated at ~180,000 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.
EST. OVERDUECriticalTiming Chain Tensioner
Service interval: 10 yr · Vehicle age: 15 yr · Past due by age
Service Timing Chain Tensioner immediately — already past the 120,000 mi / 10 yr interval
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.
EST. OVERDUECriticalWater Pump
Service interval: 8 yr · Vehicle age: 15 yr · Past due by age
Service Water Pump immediately — already past the 100,000 mi / 8 yr interval
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: 15 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. OVERDUEHighDifferential / Transfer Case Fluid
Service interval: 4 yr · Vehicle age: 15 yr · Past due by age
Service Differential / Transfer Case Fluid immediately — already past the 50,000 mi / 4 yr interval
On 4WD/AWD vehicles, neglected differential or transfer case fluid causes metal-on-metal wear. Replacement costs $1,500–$4,000.
EST. OVERDUEHighCoolant Flush
Service interval: 5 yr · Vehicle age: 15 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.
EST. OVERDUEModerateSpark Plugs (iridium/platinum)
Service interval: 8 yr · Vehicle age: 15 yr · Past due by age
Service Spark Plugs (iridium/platinum) immediately — already past the 100,000 mi / 8 yr interval
Worn spark plugs cause misfires that can foul and crack catalytic converters. A $150 tune-up can prevent a $1,200 catalytic converter replacement.
EST. OVERDUEModerateFuel Injectors
Service interval: 10 yr · Vehicle age: 15 yr · Past due by age
Service Fuel Injectors immediately — already past the 120,000 mi / 10 yr interval
Dirty or failing injectors cause rough idle, reduced fuel economy, and increased emissions. Cleaning costs $100–$200; replacement $800–$1,600.

Invalid DateELECTRICAL SYSTEM:IGNITION
SummaryGeneral Motors LLC (GM) is recalling certain model year 2011-2012 Cadillac Escalade, Escalade ESV, Escalade EXT, Chevrolet Avalanche, Silverado HD, Silverado LD, Suburban, Tahoe, GMC Sierra LD, Sierra HD, Yukon, and Yukon XL vehicles. In the affected vehicles, the ignition lock actuator may bind, making turning the key difficult or causing the ignition to get stuck in the "Start" position.Read full details...
ConsequenceIf stuck in the "Start" position, the ignition may suddenly snap back into the "Accessory" position, causing a loss of engine, steering, and braking power, increasing the risk of a vehicle crash. If the vehicle is in a crash, the air bags may not deploy, increasing the risk of occupant injury.
