Subaru BRZ Common Problems & Reliability
Developed with Toyota, the BRZ is a pure drivers car. While the engines are generally strong, they require strict oil level monitoring and can suffer from high-pressure fuel pump noise.

Most Common Subaru BRZ Faults & Repair Costs
High-Pressure Fuel Pump Chirping
The direct-injection fuel pump produces a high-pitched chirping or "crickets" sound, especially when using low-octane fuel.
Rhythmic chirping from engine bay at idle, Noise goes away with high-octane (98/99) fuel
- Listen at idle when the engine is warm
- Ask the owner what fuel they use
Valve Spring Recall
Early models were subject to a major recall for valve springs that could fail, potentially leading to engine destruction.
Rough running, Engine stalling, Catastrophic failure if spring snaps
- Verify the recall has been performed by a Subaru/Toyota dealer
- Be cautious if the engine was rebuilt poorly during the recall
Battery Drain and Weak OEM Battery
Like many Subarus, the BRZ is equipped with a relatively weak battery from the factory that can die quickly if not driven often.
Slow cranking, Flat battery after a week of sitting
- Check the age and brand of the battery
- Look for a higher-spec replacement
Clutch Slave Cylinder Leak (Manual Models)
The concentric slave cylinder (CSC) on manual BRZs can develop leaks over time, leading to a soft or spongy clutch pedal and eventually difficulty engaging gears. This is an increasingly common complaint as first-gen cars age, and fixing it requires gearbox removal.
Clutch pedal feels soft or spongy, Difficulty engaging first gear from cold, Visible fluid leak around bellhousing area
- Drive the car from cold and check clutch bite consistency
- Inspect around the bellhousing for fluid leaks
- Ask if the CSC has been upgraded during any clutch replacement
