What is the 2013-2019 Mazda CX-5 Sticking Brake Calipers and Premature Wear?
Rear brake calipers and electronic parking brake (EPB) stick or seize due to moisture accumulation in caliper brackets. This causes uneven brake pad wear, overheating, and premature failure, often before 40,000 miles. Severity: high.
What is the 2013-2021 Mazda CX-5 SKYACTIV-D 2.2 Diesel Engine Oil Dilution from Interrupted DPF Regeneration?
The 2.2 SKYACTIV-D uses post-injection of diesel into the cylinder to raise exhaust temperature for diesel particulate filter regeneration. Fuel that is not burned washes past the rings into the sump. If the engine is shut off mid-regeneration - the normal outcome of short urban… Repairs typically run $120-$4,500. Severity: high.
What is the 2013-2018 Mazda CX-5 SKYACTIV-D 2.2 Intake Shutter Valve and EGR Carbon Deposit Buildup (Diesel Recall)?
The 2.2 SKYACTIV-D runs two EGR valves and recirculates exhaust gas aggressively to meet emissions targets. Soot from that recirculated gas bakes onto the intake shutter valve, the intake manifold runners and the EGR passages; owners have found manifolds and EGR valves 80 percent… Repairs typically run $0-$1,500. Severity: high.
What is the 2013-2023 Mazda CX-5 Carbon Buildup on Intake Valves (Skyactiv)?
Direct-injection Skyactiv engines accumulate carbon deposits on intake valves due to oil vapors from the PCV system. Without port injection to clean valves, carbon can fuse to valve surfaces over time, typically appearing around 65,000+ miles. Severity: medium.
What is the 2014-2021 Mazda CX-5 Infotainment System CMU Failure (Black Screen)?
The Connectivity Master Unit (CMU) fails, causing the infotainment screen to go black, flicker, freeze, or loop repeatedly. Often caused by corrupted firmware, faulty Nav SD card contacts, or failing internal memory. Severity: medium.
What is the 2013-2022 Mazda CX-5 Premature Wheel Bearing Failure?
Wheel bearings fail prematurely due to impact damage (potholes, curbs), contamination from water/salt/grit, or manufacturing defects. Common issue across all model years. Severity: medium.
What is the 2013-2018 Mazda CX-5 Mass Airflow (MAF) Sensor Failure?
MAF sensor becomes contaminated with dirt or suffers water damage, providing incorrect air intake readings. Causes vehicle to enter "limp mode" with severe performance degradation. Severity: medium.
What is the 2013-2019 Mazda CX-5 Air Conditioning Compressor Failure?
AC compressor fails due to leaky seals, inadequate lubrication, or stress from system clogs/moisture. Common failure point for aging CX-5s, particularly in hot climates. Severity: medium.
What is the 2013-2016 Mazda CX-5 Exhaust Manifold/Gasket Leaks?
Exhaust manifold gasket becomes deformed from impact (speed bumps, road debris), causing exhaust leaks. Can also develop manifold cracks over time from heat cycling. Severity: medium.
What is the 2013-2016 Mazda CX-5 Rear Liftgate Gas Strut Corrosion and Sudden Hatch Drop (Recall 16V644)?
Insufficient corrosion-protective coating was applied to the ends of the external cylinders of the rear hatch/liftgate gas stay dampers on first-generation KE CX-5 vehicles built December 15, 2011 through December 26, 2015. Water carrying road salt enters the exposed cylinder end… Repairs typically run $0-$180. Severity: medium.
What is the 2013-2022 Mazda CX-5 Torque Converter Lock-Up Clutch Shudder / Judder (FW6A-EL Automatic)?
The six-speed FW6A-EL automatic in the CX-5 locks its torque converter clutch very early and holds it locked across a wide range to chase fuel economy. That aggressive lock-up strategy wears the lock-up clutch lining, and the resulting iron powder contaminates the ATF. Owners rep… Repairs typically run $1,200-$3,200. Severity: medium.
What is the 2013-2018 Mazda CX-5 Transaxle Bearing Whine and Rear Differential Housing Noise (AWD)?
CX-5 owners report a speed-dependent whine or hum that rises and falls with road speed but is unaffected by engine speed or gear - the classic signature of a failing gear-set bearing rather than a transmission or tire issue. Two separate sources exist. On the transaxle side, Mazd… Repairs typically run $150-$2,400. Severity: medium.
What is the 2013-2021 Mazda CX-5 Sunroof Drain Tube Disconnection and Interior Water Intrusion?
On sunroof-equipped CX-5s the front sunroof drain hoses work loose from their drain-tray nipples behind the A-pillar trim, or the tubes clog with organic debris. Because nothing visibly leaks at the headliner, water tracks down inside the pillar and body cavity and pools under th… Repairs typically run $100-$600. Severity: medium.
What is the 2013-2021 Mazda CX-5 Smart City Brake Support / i-ACTIVSENSE Malfunction and Phantom Braking?
The CX-5's Smart City Brake Support uses a laser/infrared sensor behind the windshield glass on early cars, plus a grille-mounted radar and forward camera on later i-ACTIVSENSE builds. Two distinct failure patterns are documented. First, repeated 'Smart City Brake Support malfunc… Repairs typically run $0-$1,400. Severity: medium.
What is the 2013-2020 Mazda CX-5 Front Suspension Clunking Noise?
Clunking, knocking, or rattling from front suspension caused by dry strut mount bearings, loose sway bar links, worn ball joints, or loose crossbar/cowl bolts. Severity: low.
What is the 2013-2020 Mazda CX-5 Windshield Stress Cracking Without Impact Damage?
CX-5 owners across both generations report windshields that crack with no rock chip or identifiable impact point - cracks that begin at the A-pillar edge or the lower frit band and run across the glass, sometimes appearing overnight or after a temperature swing. The thin, lightwe… Repairs typically run $350-$900. Severity: low.
