Owners frequently report a chirping noise from the clutch release bearing, various interior rattles, and a somewhat notchy feel in the manual transmission. Additionally, the high-pressure fuel pump often produces a distinct "cricket" sound, and tail light condensation can occur. Addressing these issues often starts with simple diagnostics or fluid changes. ## Problems at a glance 1. Clutch Release Bearing Chirp/Noise 2. Interior Rattles and Squeaks 3. Notchy Manual Transmission Shifting 4. High-Pressure Fuel Pump (HPFP) "Cricket" Noise 5. Tail Light Condensation ## Why these problems are common on the 2020 Subaru Brz The BRZ is a lightweight, driver-focused sports car, and some of its characteristics contribute to these common complaints. The FA20 engine's direct injection system inherently produces the HPFP "cricket" noise. The manual transmission, while robust, can feel notchy due to its design and fluid choice. Interior rattles are often a trade-off for a stiffer chassis and lighter construction. The clutch release bearing issue is a known design characteristic that persists across model years.

This noise is often attributed to the clutch release bearing (also known as the throwout bearing) and is a well-documented characteristic of the BRZ/86 platform. ### Symptoms drivers notice - Chirping or cricket-like noise from the transmission bellhousing area. - Noise is most noticeable at idle in neutral. - Noise often disappears when the clutch pedal is pressed in. - Sound may vary with engine temperature. - No impact on clutch engagement or shifting performance in most cases. ### Typical repair cost and time DIY parts: $50-$150 (bearing only, often part of a clutch kit). Shop labor: 6-8 hours ($720-$1,200) if replacing just the bearing, as it requires transmission removal. Often done during a clutch replacement, which adds $300-$600 for a full clutch kit. ### How to diagnose and fix 1. Confirm the noise by listening carefully at idle, then pressing and releasing the clutch pedal. If the noise stops when pressed, it's likely the release bearing. 2. Check for any related TSBs (e.g., Subaru TSB 03-79-16R, though for earlier models, the issue persists). 3. Consider replacing the clutch release bearing, often done as part of a complete clutch kit replacement for longevity. 4. Remove the transmission from the vehicle to access the clutch assembly. 5. Carefully remove the old release bearing and install the new one, ensuring proper lubrication of the input shaft and pivot points. 6. Reinstall the transmission and test the clutch operation. ## Problem 2: Interior Rattles and Squeaks As a lightweight, performance-oriented coupe with a stiff suspension, the 2020 Subaru BRZ is prone to developing various interior rattles and squeaks over time. Owners frequently report noises emanating from the dashboard, door panels, rear deck, and even seatbelt mechanisms, which can detract from the driving experience. ### Symptoms drivers notice - Intermittent or constant rattling sounds from the dashboard or center console. - Squeaking noises from door panels, especially over bumps or uneven roads. - Buzzing or rattling from the rear deck area or C-pillars. - Clicking or rattling from seatbelt adjusters or buckles. - Noises often worsen in colder weather or over rough pavement. ### Typical repair cost and time DIY parts: $10-$50 (felt tape, foam, plastic trim tools). Shop labor: 1-3 hours ($120-$450) for diagnosis and minor mitigation, but can be higher for extensive panel removal. ### How to diagnose and fix 1. Identify the general area of the rattle by driving on various road surfaces and having a passenger help pinpoint the source. 2. Gently press on different trim pieces, vents, and panels while driving or parked to see if the noise changes or stops. 3. Use automotive-grade felt tape, foam strips, or rubber washers to cushion contact points between plastic panels. 4. Check for loose items in glove compartments, door pockets, or under seats. 5. For persistent dash rattles, careful removal of trim panels may be necessary to access and secure loose clips or wires. 6. Ensure all screws and fasteners for interior components are properly tightened, but do not overtighten. ## Problem 3: Notchy Manual Transmission Shifting Many 2020 Subaru BRZ owners describe the manual transmission as feeling "notchy," particularly when shifting into first and second gears, especially when the transmission is cold. While not necessarily a defect, this characteristic can make shifts feel less smooth or precise than desired for some drivers. ### Symptoms drivers notice - Difficulty engaging 1st or 2nd gear smoothly, especially when cold. - A "rubbery" or "clunky" feel when shifting. - Occasional slight resistance or grind when rushing shifts. - Improved shifting feel once the transmission warms up. - No complete lockout from gears, just a less fluid engagement. ### Typical repair cost and time DIY parts: $40-$80 (for quality transmission fluid). Shop labor: 1-2 hours ($120-$300) for a transmission fluid change. ### How to diagnose and fix 1. Verify the issue by test driving the vehicle when cold and observing the shifting feel, particularly in 1st and 2nd gear. 2. Check the transmission fluid level and condition; low or old fluid can contribute to notchy shifting. 3. Consider changing the transmission fluid to a high-quality, synthetic GL-4 fluid specifically recommended for manual transmissions (e.g., Motul Gear 300, Redline MT-90). 4. Ensure the clutch pedal free play and engagement point are correctly adjusted. 5. Inspect the shifter bushings and linkage for any wear or looseness that might affect shift feel. 6. Allow adequate warm-up time for the transmission fluid before spirited driving, as cold fluid is thicker and can exacerbate notchiness. ## Problem 4: High-Pressure Fuel Pump (HPFP) "Cricket" Noise A very common and often misunderstood characteristic of the 2020 Subaru BRZ's FA20 engine is a distinct "cricket" or ticking noise emanating from the engine bay. This sound is typically produced by the high-pressure fuel pump (HPFP), which is a normal operational noise for direct injection engines, but it can be quite noticeable and concerning to new owners. ### Symptoms drivers notice - Loud ticking or chirping sound from the engine bay, especially at idle. - Noise is often more pronounced when the engine is cold or at lower RPMs. - Sound originates from the passenger side of the engine bay, near the firewall. - No associated check engine lights or performance issues. - Often mistaken for valve train noise or other mechanical problems. ### Typical repair cost and time DIY parts: $0 (it's a characteristic, not a repair). Shop labor: $0 (unless diagnostic time is spent confirming it's normal HPFP noise, which could be 0.5-1 hour, $60-$150). Aftermarket "sound deadening" solutions exist, but are not a repair. ### How to diagnose and fix 1. Listen carefully to the engine bay at idle, particularly on the passenger side near the firewall, to confirm the source of the ticking/chirping. 2. Understand that this is a normal operational noise for the direct injection system and not typically indicative of a problem. 3. If concerned, have a Subaru technician confirm the noise is indeed the HPFP and not another issue. 4. Some owners report using specific fuel additives (e.g., Techron) can slightly reduce the audibility, but this is not a permanent fix. 5. Consider aftermarket sound deadening materials for the hood or firewall if the noise is overly bothersome, though this is a cosmetic solution. 6. Monitor for any *changes* in the noise or the appearance of a check engine light, which would indicate a potential actual fault. ## Problem 5: Tail Light Condensation Some 2020 Subaru BRZ owners have reported issues with moisture or condensation accumulating inside the tail light assemblies. This can manifest as fogging or visible water droplets within the lens, which, while usually not immediately affecting light function, can be an aesthetic concern and potentially lead to long-term issues like corrosion or reduced light output. ### Symptoms drivers notice - Visible fogging or moisture droplets inside the tail light lens. - Condensation appears after washing the car, heavy rain, or in humid conditions. - Moisture may clear up on its own in dry weather but can reappear. - No immediate impact on tail light illumination. - Potential for water ingress to affect bulb sockets or wiring over time. ### Typical repair cost and time DIY parts: $10-$30 (silicone sealant, desiccant packs). Shop labor: 0.5-1 hour ($60-$150) for diagnosis and sealing, or $200-$400+ per tail light assembly for replacement if severe. ### How to diagnose and fix 1. Visually inspect the tail light assemblies for any signs of moisture inside the lens. 2. Check for obvious cracks, gaps, or damaged seals around the tail light housing. 3. Remove the tail light assembly (usually accessible from the trunk) and inspect the gasket and housing for proper sealing. 4. Apply a thin bead of clear RTV silicone sealant around the seam where the lens meets the housing, if a gap or crack is found. 5. Ensure all bulb sockets are properly seated and sealed. 6. If condensation persists or is severe, the entire tail light assembly may need to be replaced. ## Which problem to fix first For a 2020 BRZ, addressing any persistent mechanical noises like the clutch chirp or significant transmission notchy-ness should be prioritized, as these can indicate wear or potential issues that could worsen. While interior rattles and HPFP noise are annoying, they typically don't affect vehicle operation or safety. Tail light condensation is primarily an aesthetic concern. ## When to see a professional For problems like persistent clutch noise, significant transmission grinding, or any engine-related issues (beyond the normal HPFP cricket), it's best to consult a professional mechanic. DIY efforts are suitable for diagnosing and mitigating rattles, changing transmission fluid, or addressing minor condensation, but complex drivetrain or fuel system repairs require specialized tools and expertise. ## Frequently asked questions ### ### Is the 2020 Subaru BRZ a reliable car?
