The 2022 Crosstrek is a relatively new platform, so catastrophic failures are rare, but Subaru's CVT remains the weak link with cooler lines, mounts, and fluid degradation issues appearing early. The FB20/FB16 engines have mostly shed the head gasket demons of older EJs, but timing components and oil consumption show up in higher-mileage or poorly-maintained examples.
CVT Transmission Oil Cooler Line Leaks
Common · medium severityTypical onset: 40,000-80,000 mi
Symptoms: CVT fluid puddles under vehicle, usually front-center, Transmission overheating warnings on dash, Burnt smell from engine bay, Low fluid level on dipstick (if equipped)
Fix: Replace cooler lines and fittings, flush CVT fluid. 2-3 labor hours plus parts. Often covered under extended powertrain warranty if still active.
Estimated cost: $600-1,200
CVT Transmission Mount Failure
Occasional · medium severityTypical onset: 50,000-90,000 mi
Symptoms: Clunking on shifts or throttle transitions, Excessive vibration at idle in Drive, Visible sagging or torn rubber on mount inspection, Harsher engagement into Reverse
Fix: Replace rear transmission mount, sometimes front mount as well if deteriorated. 1.5-2.5 labor hours depending on access and which mount(s).
Estimated cost: $350-700
Timing Chain Tensioner and Guide Wear
Occasional · high severityTypical onset: 80,000-120,000 mi
Symptoms: Rattling noise on cold start, disappears after 10-15 seconds, Check engine light with cam/crank correlation codes (P0016, P0017), Rough idle or misfire codes if timing has walked, Metallic rattle under acceleration
Fix: Replace timing chain, guides, tensioners, and water pump while in there. Front-of-engine job, 8-10 labor hours for full kit. Subaru updated tensioner design; use latest parts.
Estimated cost: $2,500-4,000
Excessive Oil Consumption (FB Engines)
Occasional · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Low oil level between changes (1+ quart per 1,000 mi), Blue smoke on startup or hard acceleration, Fouled spark plugs, misfires, PCV valve clogged or sticky
Fix: If under warranty and oil consumption test fails, Subaru may cover short-block replacement (12+ labor hours). Out of warranty: try updated PCV valve, piston ring cleaning, or bite the bullet on pistons/rings (engine-out job). Monitor closely to avoid bearing damage.
Estimated cost: $800-1,500 for PCV/cleaning; $4,500-7,000 for pistons/rings
CVT Shuddering and Judder on Acceleration
Common · low severityTypical onset: 30,000-70,000 mi
Symptoms: Vibration or shudder during light acceleration, especially 20-40 mph, Feels like driving over rumble strips, Worse when transmission is cold, No codes, transmission fluid may look/smell normal
Fix: Subaru has issued TSBs for CVT software updates and fluid changes with additives. Flush old fluid, reflash TCM, add friction modifier. 1.5-2 labor hours. Often resolves issue temporarily; may return.
Estimated cost: $300-600
Head Gasket Seepage (Less Common on FB Engines)
Rare · high severityTypical onset: 100,000+ mi
Symptoms: Coolant weeping from head/block joint, White residue on engine exterior near heads, Slow coolant loss with no external leaks visible, Overheating or combustion gases in coolant (rare progression)
Fix: Heads-off job: resurface heads, new gaskets, timing components, water pump. 14-18 labor hours. The FB engines are far better than old EJs, but not immune if overheated or poorly maintained.
Estimated cost: $3,500-5,500
Solid daily driver with typical CVT Achilles' heel; buy a low-mileage example with service records and budget for CVT fluid changes — avoid if no maintenance history.
