The 2015 Camry is generally reliable, but the 2.5L I4 (non-hybrid) has a serious oil consumption defect that can destroy engines, and several transmission-related issues affect both four-cylinder and V6 models. The hybrid and V6 variants are notably more trouble-free.
Symptoms: Burning 1+ quart of oil every 1,000 miles with no visible leaks, Blue smoke from exhaust on cold starts or acceleration, Check engine light with P0300-P0304 misfire codes, Complete engine seizure if oil level ignored
Fix: Piston ring replacement requires 18-22 labor hours (engine stays in, oil pan and head removal). Many owners opt for short block or complete engine replacement instead due to labor overlap. Toyota extended warranty covered some cases through 150k mi but that program has ended. Prevention: check oil every 500 miles religiously.
Estimated cost: $3,500-6,000
Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: Red ATF puddles under engine bay, driver's side, Transmission running hot, harsh shifts when fluid gets low, Visible corrosion or wet spots where steel lines connect to radiator
Fix: Steel cooler lines rust through where they route near the subframe. Requires replacement of both lines (they fail together eventually). 2-3 hours labor, includes fluid refill. Inspect carefully during any transmission service—these leak before they blow.
Estimated cost: $400-700
Transmission Mount Failure (Engine Torque Mount)
Occasional · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunking when shifting from Park to Drive or Reverse, Vibration through steering wheel at idle, worse with A/C on, Visible engine movement when revving in Park
Fix: Upper transmission mount (torque strut) tears internally. The hydraulic fluid leaks out and mount collapses. Replacement takes 1.5-2 hours. OE Toyota part lasts longer than aftermarket. Easy to confirm visually—you'll see the engine sagging forward.
Estimated cost: $250-450
Electric Power Steering (EPS) ECU Failure
Occasional · high severity
Symptoms: Steering suddenly becomes very heavy with no assist, EPS warning light on dash, No noise or fluid leaks—purely electrical failure, Can occur at any mileage, including under 50k
Fix: EPS control module fails (covered by NHTSA recall 15V-635 for some VINs—check first). If not recall-eligible, module replacement is 2 hours labor plus expensive part. Some independent shops can rebuild the module for less. Steering still works mechanically but requires serious arm strength.
Estimated cost: $800-1,400
Fuel Delivery System Contamination / Filter Clogging
Rare · medium severity
Typical onset: 90,000-150,000 mi
Symptoms: Hard starting, especially when hot, Sputtering or loss of power under load, Check engine light with lean fuel mixture codes (P0171/P0174)
Fix: In-tank fuel filter is lifetime part per Toyota, but sediment buildup or bad gas causes premature failure. Requires fuel tank drop (3-4 hours labor) and pump/filter assembly replacement. Not common, but when it happens it's misdiagnosed as injectors first. Run Top Tier fuel to prevent.
Estimated cost: $600-900
Head Gasket Failure (V6 Models)
Rare · high severity
Typical onset: 120,000-180,000 mi
Symptoms: White smoke from exhaust, sweet smell, Coolant loss with no visible external leaks, Overheating or fluctuating temperature gauge, Milky oil on dipstick in severe cases
Fix: The 3.5L V6 occasionally blows head gaskets, particularly if overheated once. Requires both heads off, decking, new gaskets, timing components while apart. 16-20 hours labor. Far less common than the 2.5L oil consumption but catastrophic when it happens. Confirm with compression test and block test first.
Estimated cost: $3,200-5,000
Owner tips
2.5L I4 owners: check oil every 500 miles without fail—this engine will not warn you before it's too late
Change transmission fluid every 60k miles despite Toyota's 'lifetime' claim—extends cooler line and transmission life
Check EPS recall status by VIN before purchase; non-recalled units may still fail
V6 is the most reliable powertrain if you can live with the fuel economy; hybrid splits the difference with excellent reliability
Buy the V6 or hybrid without hesitation; avoid the 2.5L I4 unless you can verify oil consumption history or get it cheap enough to budget for an engine.

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2015 Camry, Camry Hybrid, Highlander, and Highlander Hybrid, and 2014-2015 Rav4 vehicles. A component of the electric power steering (EPS) electronic control unit (ECU) may have been damaged during the manufacturing process. Over time, this damage may result in failure of the electric power steering system.
Consequence: An unexpected loss of power steering increases the risk of a crash.
Remedy: Toyota will notify owners, and dealers will inspect the serial number of the EPS ECU or steering column assembly. If the number is within the affected range, the EPS ECU will be replaced, free of charge. The recall began on May 7, 2015. Owners may contact Toyota customer service at 1-800-331-4331.
