The 2010 WRX is a high-strung turbo boxer that rewards maintenance but punishes neglect or abuse. Most serious issues stem from the EJ255 engine's weak bottom end under boost and owners treating it like a race car on the street.
Spun Rod Bearings / Engine Knock
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Rod knock on cold start that worsens under load, Metallic rattle at idle, especially when warm, Loss of oil pressure, Metal shavings in oil filter
Fix: EJ255 rod bearings are undersized for aggressive driving. Requires full short block replacement or engine rebuild with upgraded bearings, ACL race bearings preferred. 18-24 labor hours for short block swap, 25-35 hours for full rebuild.
Estimated cost: $4,500-8,000
Ringland Failure / Piston Cracking
Common · high severity
Typical onset: 70,000-120,000 mi
Symptoms: Cylinder 4 misfire code (most common cylinder), Loss of compression on one cylinder, White smoke from exhaust under boost, Rough idle, loss of power
Fix: Piston ringlands crack due to detonation from low-octane fuel, lean AFR, or aggressive tuning. Requires complete engine teardown, piston/ring replacement on all cylinders, deck surface check. 22-28 labor hours. Forged pistons recommended for prevention.
Estimated cost: $5,000-7,500
Turbocharger Failure
Occasional · high severity
Typical onset: 90,000-140,000 mi
Symptoms: Loud whining or grinding from turbo, Blue smoke on startup or deceleration, Loss of boost pressure, limp mode, Shaft play in turbine wheel
Fix: IHI VF52 turbo fails from oil starvation (missed changes) or compressor surge from blow-off valve failures. Requires turbo replacement, new oil feed/drain lines, exhaust gaskets. 6-8 labor hours. OEM replacement or upgrade to VF39/STI turbo.
Estimated cost: $1,800-3,200
Transmission Synchro Wear (5-speed)
Common · medium severity
Typical onset: 80,000-120,000 mi
Symptoms: Grinding into 2nd gear, especially when cold, Hard to shift into 3rd under load, Gear pop-out under deceleration, Notchy shifting feel
Fix: The 5-speed's 2nd and 3rd gear synchros wear from hard shifting and clutch dumping. Requires transmission removal, full rebuild with synchro replacement. 12-16 labor hours. Many opt for 6-speed swap instead.
Estimated cost: $2,200-3,500
Banjo Bolt Filter Clogging
Occasional · high severity
Symptoms: Sudden turbo failure with no warning, Metal debris in oil system, Low oil pressure at turbo
Fix: Tiny mesh screens in turbo oil feed banjo bolts trap debris and starve the turbo. Common after engine work or in high-mileage motors. Remove screens entirely or install aftermarket banjo bolts without filters. 0.5-1 labor hour preventive, but often discovered after turbo damage.
Estimated cost: $50-150 (preventive)
Head Gasket Seepage
Occasional · medium severity
Typical onset: 100,000-150,000 mi
Symptoms: External oil seepage around cylinder heads, Slight coolant smell, no overheating, Crusty residue on block-to-head mating surface
Fix: Not the catastrophic failure seen in N/A EJs, but turbo models still seep externally. Requires heads-off service, new MLS gaskets, ARP studs recommended. 14-18 labor hours. Check for deck warpage.
Estimated cost: $2,800-4,200
Transmission Oil Cooler Line Leaks
Common · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: Red ATF puddle under engine bay, Low transmission fluid warnings, Burnt smell from transmission, Slipping or delayed shifts if severe
Fix: Metal cooler lines rust through or crack at bends. Replace both lines plus cooler if contaminated. 3-4 labor hours. Flush transmission after repair to clear debris.
Estimated cost: $400-700
Owner tips
Run 93+ octane religiously — ringland and bearing failures triple on 87 octane
Change oil every 3,500 miles with quality 5W-30 synthetic — these engines are oil-sensitive
Remove turbo banjo bolt screens as preventive maintenance before 60k miles
Avoid aggressive launches and clutch dumps — the 5-speed is glass
Get a compression test and leakdown test before purchase — cylinder 4 tells the story
Budget $1,000/year for deferred maintenance surprises if buying over 80k miles
Buy only with full service records, compression test, and a $3k emergency fund — these are maintenance-intensive performance cars that will grenade if neglected or modded poorly.
