The 2014 CX-5 is generally reliable, but suffers from a catastrophic engine defect in 2.5L models that can destroy the motor. Transmission cooler line failures and minor body/fuel system recalls round out the concern list.
2.5L Skyactiv Engine Piston Ring Failure and Oil Consumption
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Excessive oil consumption (quart every 500-1000 miles), Blue smoke from exhaust on cold start or acceleration, Loss of power, rough idle, misfires, Carbon buildup on intake valves and combustion chambers, Eventually catastrophic engine failure if driven low on oil
Fix: Mazda extended warranty to 10yr/150k on affected VINs, but many fall outside coverage. Proper fix requires engine teardown and piston ring replacement (18-22 hours) or short block replacement (20-26 hours). Some shops attempt top-end walnut blasting and decarbonizing as temporary bandaid (4-6 hours), but it returns. If you catch it early and Mazda goodwills it, you're lucky. Otherwise, you're looking at a used engine swap or rebuild.
Estimated cost: $4,500-7,500
Transmission Oil Cooler Line Corrosion and Leaks
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Transmission fluid leaking from front of vehicle near radiator, Pink or red fluid spots in driveway, Low transmission fluid level, shifting issues if neglected, Rust perforation on steel cooler lines where they connect to cooler
Fix: Steel cooler lines rust through at connections, especially in salt states. Requires replacement of cooler lines and sometimes the auxiliary transmission cooler itself. Labor is about 2-3 hours to drop undertray, drain fluid, replace lines, refill and bleed. Mazda redesigned lines but didn't recall. Catching it early prevents transmission damage.
Estimated cost: $400-750
Rear Liftgate Strut Failure and Support Bracket Corrosion
Occasional · low severity
Typical onset: 80,000-130,000 mi
Symptoms: Liftgate drops quickly or won't stay open, Sagging on one side when opened, Visible rust on strut mounting brackets, Clunking noise when opening or closing hatch
Fix: Struts wear out and brackets corrode, particularly in humid/salt environments. There was a recall (15V-574) for bracket reinforcement on some VINs. Strut replacement is straightforward (0.5-1 hour), but if brackets are compromised, structural repair or reinforcement kit is needed (2-4 hours depending on rust severity).
Estimated cost: $200-600
Front Engine Mount (Transmission Mount) Failure
Occasional · medium severity
Typical onset: 80,000-120,000 mi
Symptoms: Clunking or thudding when accelerating from stop, Vibration through cabin at idle, especially in Drive, Visible engine movement when revving in Park, Excessive drivetrain lash on throttle tip-in
Fix: The front torque mount (often called transmission mount) deteriorates and separates. It's a hydraulic mount that fails internally. Replacement requires supporting the engine/trans and removing the mount (2-3 hours). OEM mount recommended; aftermarket versions often fail prematurely. Not difficult, just time-consuming due to access.
Estimated cost: $350-600
Fuel Filler Pipe Corrosion and Check Engine Light
Occasional · low severity
Typical onset: 60,000-100,000 mi
Symptoms: P0442, P0455, P0456 EVAP codes, Fuel smell near rear of vehicle after fill-up, Difficulty filling tank, pump clicks off repeatedly, Visible rust or holes in filler neck
Fix: Filler neck rusts through where it connects to tank, causing EVAP leaks. Mazda issued recall 1817F for some VINs. If not covered, replacement involves dropping exhaust heat shields and disconnecting hoses (2-3 hours). Smoke test confirms leak location. Salt-state vehicles worst affected.
Estimated cost: $400-700
Windshield Wiper Motor Failure and Linkage Binding
Rare · medium severity
Symptoms: Wipers stop mid-sweep or park incorrectly, Slow or intermittent wiper operation, Grinding or clicking noise from cowl area, Wipers work on some speeds but not others
Fix: Wiper motor or linkage bushings fail, causing binding. Recall 16V-576 addressed wiper motor software, but mechanical failures still occur. Motor replacement requires cowl cover removal (1.5-2 hours). Linkage bushings can be serviced separately if motor is okay. Test motor independently before replacing entire assembly.
Estimated cost: $250-500
Owner tips
Check oil level every 500 miles on 2.5L engines — if it's consuming oil, document it immediately for potential Mazda goodwill claim
Inspect transmission cooler lines annually if you live in salt states; catch rust early before lines perforate
Use Top Tier gasoline and occasional Italian tune-up (high-RPM highway runs) to minimize carbon buildup on direct-injection engines
Verify recall completion (liftgate, filler neck, wiper motor) before purchase; use Mazda VIN lookup tool
Buy the 2.0L if you must have a 2014, or skip to 2016+ after Mazda addressed piston ring issues — the 2.5L engine grenade risk is too high unless you confirm it's already been rebuilt under warranty.

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.
STEERING · 16V203000

Mazda North American Operations (Mazda) is recalling certain model year 2016 CX-3 vehicles manufactured June 1, 2015, to December 2, 2015, 2013-2014 Mazda2 vehicles manufactured July 3, 2013, to August 8, 2014, 2014-2016 CX-5 vehicles manufactured January 19, 2013, to December 2, 2015, and 2013-2015 CX-9 vehicles manufactured December 6, 2012, to July 31, 2015. The lower mounting nuts and bolts that attach the front strut assembly to the steering knuckle may loosen, allowing the steering knuckle to separate.
Consequence: If the steering knuckle separates from the strut assembly, it can cause a loss of steering control, increasing the risk of a crash.
Remedy: Mazda will notify owners, and dealers will inspect the lower mounting nuts and bolts that secure the front strut assembly to the steering knuckle. If the bolts are loose, they will be replaced and then correctly tightened, free of charge. The recall is expected to begin May 20, 2016. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 9316D.
FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY:FILLER PIPE AND CAP · 16V064000
2016-02-03
Mazda North American Operations (Mazda) is recalling certain model year 2014-2016 Mazda CX-5 vehicles manufactured June 27, 2013, to February 2, 2016. The affected vehicles have a fuel filler pipe that may rupture in the event of a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 301, "Fuel System Integrity."
Consequence: A rupture of the fuel filler pipe may result in a fuel leak, increasing the risk of a fire.
Remedy: Mazda will notify owners, and dealers will alter the attachment between the fuel filler pipe and the left rear side of the bracket of the fuel filler pipe, free of charge. The recall began on February 25, 2016. Owners may contact Mazda customer service at 1-800-222-5500, option 6. Mazda's number for this recall is 9216B.
VISIBILITY:WINDSHIELD · 16E002000
2016-01-19
Pilkington North America, Inc. (Pilkington) is recalling certain replacement windshields, model FW04026 GTY, manufactured November 23, 2015, to December 16, 2015 for use in Mazda CX-5 vehicles that are equipped with the Smart City Brake Support system. The affected windshields have a bracket mounted on the inside to hold a laser sensor or LIDAR device for the Smart City Brake Support system. These brackets were improperly affixed with only tape instead of tape and urethane and therefore may loosen.
Consequence: If the bracket loosens or detaches from the windshield, the safety features of the Smart City Brake Support system may be disabled and therefore increase the risk of a crash.
Remedy: Pilkington will contact the wholesalers and retailers that purchased the windshields to try to identify the affected customers. The affected windshields will be replaced, free of charge. This recall began on February 15, 2016. Owners may contact Pilkington at 1-844-278-7230.
