The 2013 CX-5 is Mazda's first-generation compact crossover built on the SKYACTIV platform. While generally reliable, early examples suffer from specific powertrain issues that can be catastrophic if ignored, plus some typical automatic transmission cooling problems.
Skyactiv 2.5L Piston Ring Failure and Oil Consumption
Occasional · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Excessive oil consumption (1 quart per 1,000 miles or worse), Blue smoke from exhaust on cold start or acceleration, Carbon buildup on intake valves causing rough idle, P0301-P0304 misfire codes, Low compression on one or more cylinders
Fix: Early SKYACTIV 2.5L engines have defective piston ring design causing oil burning. Mazda extended warranty to 10yr/150k for some VINs but many are now out of coverage. Proper fix requires complete engine teardown, new pistons and rings, cylinder honing, valve cleaning. 18-24 labor hours for full rebuild. Some shops do short-block replacement at 14-16 hours if block is scored.
Estimated cost: $4,500-7,500
Automatic Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Transmission fluid puddles under vehicle near radiator area, Low transmission fluid level on dipstick check, Harsh or delayed shifts when fluid gets low, Pink fluid staining (ATF mixed with coolant if cooler fails internally)
Fix: The steel transmission cooler lines running to the radiator corrode where they connect, especially in salt-belt states. External leaks are straightforward: replace both hard lines and any deteriorated rubber sections. 2-3 hours labor. If cooler fails internally and mixes ATF with coolant, you need radiator replacement plus full transmission flush. 4-6 hours total.
Estimated cost: $350-650 for lines only, $1,200-1,800 if radiator contaminated
Rear Transmission Mount Collapse
Common · low severity
Typical onset: 80,000-130,000 mi
Symptoms: Clunking when shifting from Park to Drive or Reverse, Excessive vibration at idle in Drive, Drivetrain shudder during acceleration from stop, Visible sag or torn rubber on mount inspection
Fix: The rear transmission mount uses a hydraulic design that fails prematurely. The rubber tears and fluid leaks out, causing excessive drivetrain movement. Replacement requires supporting the transmission from below. 1.5-2 hours labor. OEM mount recommended as aftermarket versions fail quickly.
Estimated cost: $250-400
Skyactiv 2.0L Carbon Buildup on Intake Valves
Common · medium severity
Typical onset: 60,000-90,000 mi
Symptoms: Rough idle when engine warm, Hesitation or stumble during light acceleration, Reduced fuel economy (2-4 mpg drop), P0300 random misfire or cylinder-specific misfire codes, Hard starting after sitting overnight
Fix: Direct injection engines have no fuel washing the intake valves, so carbon accumulates. The 2.0L is especially prone. Walnut-blasting service through intake manifold is standard fix: remove manifold, manually clean all four intake runners and valves. 4-5 hours labor. Catch-can installation helps prevent recurrence but requires oil change intervals under 5,000 miles to be effective.
Estimated cost: $450-750
High-Pressure Fuel Pump Failure (2.5L)
Occasional · high severity
Typical onset: 50,000-100,000 mi
Symptoms: No-start condition with cranks but won't fire, Engine dies while driving and won't restart, Metal shavings in fuel filter or fuel system, P0087 fuel rail pressure too low code, Rough running or misfires under load
Fix: The cam-driven high-pressure fuel pump can fail internally, sending metal debris through the fuel system. Requires pump replacement plus cleaning entire fuel system including injectors and rails. If metal contamination is severe, all four injectors need replacement. 6-8 hours for pump and system flush, up to 12 hours if injectors also needed.
Estimated cost: $1,200-2,000 for pump/flush, $2,800-4,200 with injectors
Liftgate Strut Failure and Hinge Corrosion
Common · low severity
Typical onset: 70,000-110,000 mi
Symptoms: Liftgate falls suddenly instead of staying open, Creaking or binding when opening liftgate, Visible rust on hinge pivot points, Liftgate won't stay up in windy conditions, Power liftgate struggles to open fully (if equipped)
Fix: Liftgate support struts weaken over time and hinge pivots corrode, especially in humid climates. Struts are 0.5 hour per side, hinges require 2-3 hours if pivot points are seized. One NHTSA recall addressed some hinge issues but not all years/VINs covered. Inspect and lubricate hinges annually to prevent binding.
Estimated cost: $150-250 for struts, $400-700 for hinge service
Owner tips
Check oil level every 1,000 miles on 2.5L engines — consumption above 1 qt per 3,000 miles indicates ring problems developing
Change transmission fluid at 50,000 mile intervals instead of Mazda's 'lifetime' recommendation to prevent cooler and valve body issues
Use Top Tier gasoline and consider intake valve cleaning service every 50,000-60,000 miles on direct-injection models
Inspect transmission cooler lines and hoses annually in rust-belt states, replace at first sign of surface rust
Avoid extended oil change intervals — 5,000 miles maximum with quality synthetic to minimize carbon buildup and ring wear
Decent platform if you avoid high-mileage 2.5L engines with unknown service history and budget for proactive transmission maintenance — the piston ring issue is a deal-breaker without documentation of repair or very low mileage.

Mazda North American Operations (Mazda) is recalling certain model year 2010-2013 Mazda3 and Mazdaspeed3 vehicles manufactured November 18, 2008, to June 8, 2013, 2012-2015 Mazda5 vehicles manufactured October 26, 2010, to June 22, 2015, 2016 CX-3 vehicles manufactured June 1, 2015, to December 26, 2015, and 2013-2016 CX-5 vehicles manufactured December 15, 2011, to December 26, 2015. On the affected vehicles, the lift gate support struts may corrode, possibly causing the struts to break and/or the lift gate to drop unexpectedly.
Consequence: If the lift gate falls unexpectedly, it may hit the user, increasing their risk of injury.
Remedy: Mazda dealers will replace the both lift gate supports, free of charge, however parts are not currently available. The recall began April 2017. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 9916H.
