The 2014 Impreza is generally a reliable commuter with Subaru's proven FB20/FB25 engines, but shares the brand's persistent head gasket vulnerability and CVT-related concerns that can become expensive past 100k miles.
CVT Transmission Shudder and Overheating
Common · high severityTypical onset: 80,000-140,000 mi
Symptoms: Judder or shudder during acceleration from stop or low-speed rolling, Transmission overheating warnings on highway climbs or towing, Delayed engagement when shifting from Park to Drive, Whining or groaning noises during acceleration
Fix: Transmission fluid replacement with Subaru High Torque CVT fluid can help temporarily (2 hrs), but worn valve bodies or torque converter typically require transmission replacement or rebuild. External cooler addition is preventive (3-4 hrs). Full CVT replacement is 8-10 hrs labor.
Estimated cost: $4,500-7,000
Head Gasket Weeping and Failure
Occasional · high severityTypical onset: 100,000-150,000 mi
Symptoms: External coolant seepage visible below cylinder heads, White residue or crusty buildup on engine block sides, Overheating under load or slow coolant loss with no visible leaks, Sweet coolant smell from engine bay after driving
Fix: Both head gaskets must be replaced; job includes head resurfacing, timing components, and water pump replacement. 12-16 hrs labor for both sides. Many shops recommend doing timing belt/chain service simultaneously since engine is apart.
Estimated cost: $2,800-4,200
Piston Ring Land Failure and Oil Consumption
Occasional · high severityTypical onset: 60,000-120,000 mi
Symptoms: Excessive oil consumption—1 quart per 1,000-2,000 miles, Blue smoke from exhaust on cold start or hard acceleration, Misfires or rough idle when oil level drops, Engine knocking if oil starvation occurs
Fix: Subaru had an extended warranty for 2012-2014 models (ended 2019). Requires short block replacement with updated pistons. 18-22 hrs labor for complete short block swap including gaskets and seals.
Estimated cost: $5,000-8,000
Rear Wheel Bearing Failure
Common · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Growling or humming noise from rear that increases with speed, Noise changes pitch during cornering—louder on turns, Vibration felt through seat at highway speeds, ABS warning light if bearing disintegrates and damages tone ring
Fix: Rear wheel hub assemblies are pressed-in units requiring bearing press or hub replacement. 2-3 hrs per side. Rears fail more frequently than fronts on this chassis.
Estimated cost: $350-550
Brake Light Switch Failure
Common · medium severitySymptoms: Brake lights stay on constantly, killing battery overnight, Brake lights don't illuminate when pedal pressed, Cruise control won't engage or disengage erratically, Push-button start refuses to release shifter from Park
Fix: Switch is mounted above brake pedal assembly. Subject to NHTSA recall 14V-355 but many fail outside recall criteria. 0.5-1 hr labor for switch replacement.
Estimated cost: $120-220
Transmission Mount Deterioration
Occasional · low severityTypical onset: 90,000-130,000 mi
Symptoms: Clunking when shifting from Reverse to Drive, Excessive vibration at idle in Drive with brake applied, Visible engine/transmission movement when revving in Park, Harsh engagement feel during gear changes
Fix: Rear transmission mount (crossmember mount) fatigues and tears. Replacement requires lifting transmission slightly. 1.5-2 hrs labor.
Estimated cost: $250-400
Solid economy car if you find one with documented CVT services and no oil consumption history—avoid high-mileage examples without maintenance records or budget $3-5k for eventual CVT or engine work.
