2005 SUBARU LEGACY

Typical onset: 90,000-150,000 mi

Symptoms: Coolant seepage from cylinder head seams, visible as dried white/green residue, Sweet coolant smell after driving, especially on cold starts, Slow coolant loss requiring top-offs every few weeks, Oil and coolant mixing is rare on external failures but catastrophic when it happens

Fix: Replace both head gaskets, resurface heads, new timing components, water pump, all coolant hoses. 12-16 hours labor. Do NOT patch—it will fail again within 20k miles.

Estimated cost: $2,000-3,200

Typical onset: 80,000-130,000 mi

Symptoms: ATF puddles under engine bay, often near radiator, Rapid transmission fluid loss leading to slipping or no movement, Rust perforation on steel lines running to radiator-mounted cooler, Sudden loss of all gears if line ruptures while driving

Fix: Replace both transmission cooler lines (they rust as a pair). 2-3 hours labor. Flush transmission if contamination suspected. This is a tow-home failure if it lets go on the highway.

Estimated cost: $400-700

Typical onset: 100,000-160,000 mi

Symptoms: Grinding or humming from rear that increases with speed, ABS/VDC warning lights if sensor damaged by failing bearing, Vibration through seat at highway speeds

Fix: Press out old bearing, press in new hub assembly. 2-3 hours per side labor. Bearings tend to go one at a time, plan for the other within 30k miles.

Estimated cost: $350-550 per side

Typical onset: 70,000-120,000 mi

Symptoms: Clicking or popping when turning at low speeds, Grease splatter on inner wheel well or suspension components, Vibration during acceleration if joint is worn

Fix: If caught early (torn boot, no clicking), repack and re-boot for 1.5 hours labor. If clicking, replace entire axle (2 hours). Most shops just replace the axle—cheaper than labor to repack.

Estimated cost: $250-450 per side for axle replacement

Symptoms: Intermittent no-start, dash lights flicker or stay dark, Key won't turn or gets stuck in ignition, Electrical gremlins—windows, radio, gauges cutting out randomly, Vehicle stalls while driving in worst cases

Fix: Replace ignition switch assembly. Recall covers some VINs, but many owners report being outside recall scope. 1.5-2 hours labor if paying out of pocket.

Estimated cost: $0 if recall applies, $250-400 if not

Typical onset: 120,000+ mi or 10+ years in rust belt

Symptoms: Soft or spongy brake pedal that doesn't firm up with pumping, Brake fluid leaking at line junctions or along frame rails, Catastrophic brake loss if line ruptures

Fix: Replace corroded sections or full brake line set if multiple lines are compromised. 4-6 hours labor for full replacement. Inspect annually if car has seen road salt.

Estimated cost: $500-1,200 depending on extent

Typical onset: 80,000-130,000 mi

Symptoms: Clunk when shifting from Park to Drive or Reverse, Excessive vibration at idle, smooths out at higher RPM, Engine rocks visibly when revved in Park

Fix: Replace transmission mount (most common failure) or all four engine mounts if deteriorated. Transmission mount alone is 1-1.5 hours labor.

Estimated cost: $150-300 for trans mount, $600-900 for all mounts
