The 1st-gen Crosstrek is a capable AWD hatch; oil consumption and the CVT are the main checks.
Compiled & reviewed by the VehicleFaults Research Team · last reviewed July 2026
The most commonly reported faults on the 2013–2017 Subaru Crosstrek are FB20 oil consumption, Clunking noises from the rear over uneven surfaces or a visibly sagging ride height due to snapped rear coil springs and Acrid burning smell in the cabin after driving, caused by engine oil weeping from the cam carriers onto the exhaust manifold. 3 of the documented issues are rated high severity · inspect these first. Full inspection points, onset mileage and what to check are listed below.

Build my inspection planYes overall; oil consumption on the FB engine is the key thing to monitor.
Some FB20 engines consume oil; check the level regularly.
Generally, with fluid service; test for shudder on the drive.
The first-generation Crosstrek is fitted with the FB20 2.0-litre petrol engine, which utilises a timing chain rather than a rubber belt. This chain is designed to last the lifetime of the vehicle and does not require routine replacement, provided the engine receives regular oil changes to maintain proper tensioner lubrication.
Yes, Subaru’s Symmetrical All-Wheel Drive system is highly sensitive to variations in rolling circumference. Fitting mismatched tyres or mixing new rubber with worn tyres can cause excessive heat and premature failure in the centre differential. Always ensure tread depths across all four corners are within two to three millimetres.
The Crosstrek boasts a substantial 220mm of ground clearance, which is unusually high for a hatchback-based crossover. While this provides excellent rough-track capability, the increased CV joint angles mean the driveshaft gaiters are prone to accelerated wear. Always inspect the inner and outer boots carefully to avoid MOT failures.
