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 2013-2023 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 2017-2021 Mazda CX-5 Rust on Door Panels and Body?
Interior door panels rust due to improper drainage design allowing water accumulation. Some colors (Soul Red, Machine Grey) have thin paint causing premature rust bubbling on roof and body panels. 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 2016-2020 Mazda CX-5 Electronic Parking Brake (EPB) Actuator / Connector Malfunction?
CX-5 trims with the electronic parking brake can throw an 'Electric parking brake malfunction' warning with the brake failing to fully release or engaging on only one side. Common causes are a failed EPB caliper actuator motor and, frequently, a bent/corroded pin in the actuator… Repairs typically run $150-$900. 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 2016-2023 Mazda CX-5 Timing Chain Cover Oil Weep and Water Pump Coolant Seepage (SKYACTIV-G)?
SKYACTIV-G engines are widely reported to develop a slow oil weep at the timing chain cover, where the factory RTV/silicone sealant is applied inconsistently at the seam. Owners find oily film at the front-lower timing-cover area, often discovered at oil-change inspections. Separ… Repairs typically run $400-$1,400. Severity: low.
What is the 2017-2023 Mazda CX-5 i-stop AGM Battery Premature Failure / Start-Stop System Malfunction?
CX-5 models with i-stop (idle stop) use a specific AGM/EFB battery and a battery-management system that monitors charge state to decide whether to allow auto stop-start. The factory battery is undersized (around 480 CCA new) and degrades early; as it weakens, owners get an i-stop… Repairs typically run $200-$350. Severity: low.
