On the 2006-2015 Mazda Mazda5, the Mazda5 sliding door cables fray and break, preventing the sliding doors from opening or closing properly. The cable runs through a pulley system that wears over time, and the steel cable eventually fatigues from repeated bending cycles. This is the most common Mazda5 complaint and affects both manual and power sliding door variants.
Replace sliding door cable assembly. OEM cables are available (C235-73-760F for driver side, C235-72-760F for passenger side). The replacement involves removing the door interior panel and routing the new cable through the pulley system. Some owners upgrade to aftermarket cables with Teflon coating for longer life.

On the 2006-2015 Mazda Mazda5, the Mazda5's manual sliding doors develop latch and striker alignment problems over time. The door becomes difficult to close, requiring excessive force, or fails to latch securely. The striker bolts loosen and the latch mechanism wears. In some cases the door opens unexpectedly while driving if the latch doesn't fully engage. The issue is accelerated by child use (force of kids slamming the door).
Adjust the striker plate alignment (loosen bolts, reposition, retighten). Lubricate the latch mechanism with white lithium grease. Replace the door latch assembly if worn ($100-$200). Check the lower door roller for wear as it can cause misalignment. Tighten the striker mounting bolts to specification. Inspect the door check mechanism and replace if the door doesn't hold in the open position.

On the 2006-2015 Mazda Mazda5, the upper transmission mount on the Mazda5 fails prematurely, typically between 50,000-80,000 miles. The rubber isolator collapses, causing excessive engine/transmission movement. This results in clunking during shifts, vibration at idle, and accelerated wear on CV axles and other drivetrain components.
Replace the upper transmission mount and inspect the lower engine mount and rear torque mount at the same time. All three mounts should be replaced as a set if any show deterioration. OEM mounts are preferred over aftermarket for NVH characteristics.

On the 2006-2015 Mazda Mazda5, the A/C evaporator core in the Mazda5 develops pinhole leaks from internal corrosion, causing refrigerant loss. The evaporator is located behind the dashboard, making replacement extremely labor-intensive. Corrosion is accelerated by moisture trapped in the cabin air filter area and infrequent cabin filter replacement.
Replace the A/C evaporator core. This requires dashboard removal, making it one of the most labor-intensive A/C repairs. Replace the receiver/drier, expansion valve, and O-rings at the same time. Regular cabin air filter changes help prevent the moisture buildup that accelerates corrosion.

On the 2006-2015 Mazda Mazda5, the Mazda5's EGR valve and the passages in the intake manifold clog with carbon deposits, causing rough idle, hesitation, and stalling. The issue is accelerated by short-trip driving and city use (which is common for a minivan). The EGR passage in the intake manifold is particularly narrow on this engine and clogs completely by 80,000-100,000 miles.
Remove and clean the EGR valve with carb cleaner ($0 if DIY). Clean the EGR passage in the intake manifold with a wire brush and solvent — this is the critical step most shops skip. Replace the EGR valve gasket. If the valve diaphragm is damaged, replace the entire valve ($100-$200). Italian tune-ups (highway driving at higher RPM) help reduce carbon buildup when done regularly.
