The most critical and costly common problem for the Toyota 86 (and its twins, the Subaru BRZ and Scion FR-S) is engine oil starvation leading to catastrophic failure, primarily caused by excess RTV sealant clogging the oil pickup tube. This issue affects engines, particularly those driven hard on track or with high G-load cornering. Other prevalent problems include high oil consumption, a noticeable "torque dip" in acceleration, premature clutch release bearing failure, and various minor electrical and body quirks.
While the FA20 boxer engine is generally robust when maintained, several key failure points demand attention from owners and prospective buyers. The oil starvation issue is a design-related flaw where the factory-applied silicone sealant (RTV) on the timing chain cover can dislodge over time. These fragments travel through the oil system and accumulate on the oil pickup screen, restricting flow. During sustained high-RPM use or aggressive cornering, this can lead to a sudden loss of oil pressure and subsequent spun rod bearings or complete engine seizure. This is not just a theoretical risk; it is a well-documented failure mode in the enthusiast community, often occurring on modified or tracked cars.
Beyond the oil pickup clog, the engine is also known for higher-than-average oil consumption. Many owners report the need to add a quart of oil between standard 5,000-mile change intervals, especially in higher-mileage examples or those subjected to spirited driving. Monitoring oil levels frequently is considered essential preventative maintenance for this platform.
A significant factory recall targeted early models (2012-2013) for faulty valve springs. According to Toyota's official recall documentation (Recall No. 19TB07/19TA07 in the U.S.), improper manufacturing could cause the springs to break. The repair process for this recall was itself problematic. If the procedure was not followed meticulously—particularly if debris entered the engine during disassembly—it could lead to immediate or near-term engine knocking and failure post-service. A car's vehicle identification number (VIN) should be checked to confirm recall completion status.
| Issue | Affected Model Years | Key Concern | Typical Symptom/Outcome |
|---|
| Valve Spring Recall | 2013 (and some 2012-2014) | Faulty valve springs may break. | Potential engine failure. Critical to verify repair history. |
| Excess RTV Sealant | All years (FA20 engine) | Clogs oil pickup screen. | Oil starvation, spun bearings, engine seizure. |
| High Oil Consumption | All years (FA20 engine) | Consumes > 1 qt per 5,000 miles. | Low oil level warnings, risk of engine damage if ignored. |
The drivetrain has two other common complaints. The manual transmission is known for premature clutch release bearing failure, often manifesting as a squealing or chirping noise when the clutch pedal is depressed. Furthermore, drivers universally note a "torque dip"—a noticeable drop in power between approximately 3,000 and 4,500 RPM. This flat spot in the power band is an inherent characteristic of the factory tune and exhaust system, though it is easily addressed with aftermarket modifications like a header and a tune.
Smaller, non-critical issues are widespread. A high-pitched "cricketing" noise from the high-pressure fuel pump is ubiquitous but harmless. Interior trim rattles, thin paint prone to chipping, and condensation inside tail lights are frequent owner-reported nuisances. When purchasing a used 86/BRZ/FR-S, a thorough pre-purchase inspection and proof of consistent, documented maintenance are more critical than for an average commuter car, given its typical usage profile.
