2014 DAIHATSU MIRA

Typical onset: 70,000-110,000 mi

Symptoms: Ticking or tapping noise from engine on cold start that may persist when warm, Loss of power or rough idle as lifters collapse, Check engine light with misfire codes in severe cases

Fix: The KF engine's hydraulic lifters wear prematurely with irregular oil changes or wrong viscosity oil. Full lifter replacement requires 6-8 hours labor with cylinder head removal. Critical to flush oil system and verify oil pressure before reinstalling head.

Estimated cost: $1,200-2,100

Typical onset: 80,000-130,000 mi

Symptoms: Transmission overheating warning light or limp mode in traffic, Burnt smell from transmission area, Shuddering or delayed engagement when hot, Metallic particles in CVT fluid

Fix: The external CVT oil cooler clogs or the internal cooler in the radiator fails, causing catastrophic transmission damage if ignored. Replacement involves 4-5 hours labor, full CVT fluid flush, and sometimes transmission pan gasket. Must use Daihatsu CVTF or exact equivalent.

Estimated cost: $800-1,500

Typical onset: 90,000-140,000 mi

Symptoms: Rattling noise from front of engine on startup that fades after 10-15 seconds, Check engine light with cam/crank correlation codes (P0016, P0017), Rough running or poor fuel economy, In severe cases, won't start or sudden stalling

Fix: The KF engine uses a chain with plastic guides that deteriorate. Requires full timing cover removal, chain, guides, tensioner, and both VVT gears—10-13 hours labor. Engine must be out or front subframe dropped for access. Critical to check camshaft wear at the same time.

Estimated cost: $2,200-3,800

Typical onset: 60,000-100,000 mi

Symptoms: White smoke from exhaust on cold start, Coolant loss with no visible leaks, Overheating in traffic or on inclines, Milky residue on oil cap or dipstick, Bubbling in coolant reservoir with engine running

Fix: The small 660cc engine runs hot and head gaskets fail if the cooling system isn't maintained or if the CVT cooler cross-contaminates. Head removal, machining, new gasket set, and lifter inspection takes 8-11 hours. Always check head for warpage and cracks—these aluminum heads don't tolerate much overheating.

Estimated cost: $1,800-3,200

Typical onset: 100,000-150,000 mi

Symptoms: Severe vibration at idle that worsens with RPM, Squealing or grinding from front of engine, Accessory belt misalignment or repeated belt failures, Visible wobble of crankshaft pulley

Fix: The rubber damper ring separates from the hub, causing catastrophic vibration that can damage crankshaft bearings. Replacement requires 2-3 hours labor with special puller tools. If caught early before bearing damage, it's a straightforward job—if ignored, it becomes an engine rebuild.

Estimated cost: $400-700

Typical onset: 60,000-90,000 mi

Symptoms: Clunking when shifting from Park to Drive or Reverse, Excessive vibration at idle in gear, Visible sag or movement of transmission when revving, Increased cabin noise from drivetrain

Fix: The CVT is rubber-mounted and the mounts deteriorate faster due to heat from the transmission. Front and rear mounts usually need replacing together—3-4 hours labor with proper support equipment. Cheap aftermarket mounts fail quickly; use OEM or high-quality replacements.

Estimated cost: $350-650
