2017 KIA SORENTO

Typical onset: 60,000-120,000 mi

Symptoms: knocking or ticking noise from engine that progressively worsens, metal shavings in oil, sudden loss of power or complete seizure, check engine light with bearing or timing codes, engine runs rough then dies completely

Fix: Complete engine replacement or rebuild required. Metal debris from manufacturing contaminated bearings and causes rod knock, spun bearings, and seized crankshafts. Kia extended warranty to 10yr/100k on powertrain but many fail just outside that window. Short block replacement takes 18-24 labor hours, full longblock 22-28 hours if heads are damaged.

Estimated cost: $5,500-8,500

Typical onset: 70,000-110,000 mi

Symptoms: transmission fluid pooling under vehicle, low fluid warning or slipping gears, fluid dripping near front of transmission, burnt smell if fluid level drops significantly

Fix: Oil cooler lines crack or fittings fail where they connect to radiator. Subject of recall but many vehicles still affected. Replace both cooler lines and reseal connections, flush contaminated coolant if cross-contamination occurred. 2-3 labor hours plus fluid refill.

Estimated cost: $350-650

Typical onset: 80,000-130,000 mi

Symptoms: clunking when shifting from park to drive or reverse, excessive vibration at idle, visible sag or tearing in rubber mount, transmission moves excessively when accelerating hard

Fix: Rubber isolator in transmission mount deteriorates prematurely, especially on AWD models with heavier drivetrain load. Requires lifting engine/trans slightly to replace mount. 1.5-2.5 labor hours depending on access.

Estimated cost: $250-450

Typical onset: 90,000-140,000 mi

Symptoms: rough idle and misfires, poor fuel economy, hesitation on acceleration, hard starting especially when cold, fuel smell or visible leak at injector seals

Fix: Direct injection system carbon buildup clogs injectors, and high-pressure pump fails prematurely. Often need to replace multiple injectors at once plus pump. Requires fuel system depressurization and intake manifold removal. 6-8 hours for injector set plus pump.

Estimated cost: $1,800-2,800

Symptoms: water dripping from headliner near A or C pillars, wet carpet in footwells after rain, musty smell in cabin, water stains on headliner

Fix: Drain tubes clog with debris and cause water to back up into cabin. Requires removing A-pillar trim and sometimes headliner panels to access tubes, blow them clear, and reseal connections. 2-4 hours depending on how many tubes are clogged.

Estimated cost: $200-500

Typical onset: 100,000-150,000 mi

Symptoms: parking brake will not release or apply, EPB warning light stays on, grinding noise from rear brakes, parking brake engages randomly while driving

Fix: EPB actuator motor or control module fails. Requires replacing actuator assembly on affected caliper, sometimes both rears for matching wear. Must be programmed with scan tool after installation. 2-3 hours per side.

Estimated cost: $600-1,200
