So, you're thinking about or maybe already cruising around in a Toyota 86, Scion FR-S, or Subaru BRZ from 2016? These cars are a blast! But like any vehicle, they can have their quirks. Let's dive into some common issues you might encounter and, more importantly, how to tackle them.

Understanding the Appeal and Potential Pitfalls

The Toyota 86, Scion FR-S (RIP Scion!), and Subaru BRZ – affectionately known as the "Toyobaru" twins – captured the hearts of driving enthusiasts with their rear-wheel-drive layout, nimble handling, and affordable price point. The 2016 model year falls squarely within the first generation, which means certain common issues have become well-documented. Knowing these beforehand can save you headaches down the road.

Before we get into the nitty-gritty, it's important to remember that not every car experiences every problem. However, being aware of these potential issues allows you to be proactive with maintenance and address concerns early. Also, keep in mind that driving style and environmental conditions can significantly impact a car's reliability. A car that's been tracked regularly will likely show wear and tear sooner than one that's primarily used for gentle commuting.

One of the biggest factors contributing to potential issues is the direct injection fuel system used in these cars. While direct injection improves fuel economy and performance, it can also lead to carbon buildup on the intake valves. This buildup restricts airflow, reducing engine performance and potentially causing misfires. We'll discuss this further in the carbon buildup section.

Another area of concern for some owners is the fuel pump. Some 2016 models have experienced fuel pump failures, leading to stalling or difficulty starting. While this isn't a widespread issue, it's worth being aware of the symptoms and potential fixes. Addressing these kinds of issues is crucial for maintaining the long-term health and performance of your vehicle.

Finally, keep in mind that preventative maintenance is key. Regular oil changes, air filter replacements, and spark plug maintenance can go a long way in preventing larger problems from developing. Following the manufacturer's recommended maintenance schedule is always a good idea. These cars, while generally reliable, do benefit from attentive care.

Common Issues and Solutions

Let's break down some of the most common problems reported by 2016 Toyota 86/Scion FR-S/Subaru BRZ owners, along with potential solutions:

1. Carbon Buildup on Intake Valves

Carbon buildup is a notorious issue in direct injection engines, and the FA20 engine in the Toyobaru twins is no exception. Because fuel is injected directly into the cylinders, it doesn't wash over the intake valves, leaving them vulnerable to carbon deposits from oil vapors and exhaust gases. Over time, this buildup restricts airflow, leading to:

• Reduced engine performance
• Rough idling
• Poor fuel economy
• Misfires
• Check engine light

Solutions:

• Walnut Blasting: This is the most effective way to remove carbon buildup. It involves blasting the intake valves with crushed walnut shells, which effectively scrubs away the deposits without damaging the valves. This process usually requires a professional and can cost a few hundred dollars, but it's a worthwhile investment.
• Chemical Cleaners: There are fuel additives and intake cleaners that claim to dissolve carbon deposits. While these may offer some benefit, they're generally not as effective as walnut blasting for severe buildup. If you choose this route, be sure to use a product specifically designed for direct injection engines.
• Oil Catch Can: Installing an oil catch can helps prevent oil vapors from entering the intake manifold in the first place, reducing the rate of carbon buildup. It's a relatively inexpensive modification that can offer long-term benefits. This is a great preventative measure to take after cleaning the valves.
• Regular Italian Tune-ups: Occasionally driving the car hard (once the engine is fully warmed up, of course!) can help burn off some of the carbon deposits. This involves running the engine at high RPMs for short periods. While not a complete solution, it can help slow down the buildup process. Always be safe and responsible when doing this, and only do it on a closed course or in a safe, legal environment.

Addressing carbon buildup early can prevent more serious problems down the road. Don't ignore symptoms like rough idling or a noticeable decrease in performance. Regular maintenance and preventative measures are key to keeping your engine running smoothly.

2. Fuel Pump Issues

Some 2016 Toyota 86/Scion FR-S models have experienced fuel pump failures. This can manifest as:

• Difficulty starting
• Stalling, especially at low speeds
• Hesitation during acceleration
• Check engine light

Solutions:

• Fuel Pump Replacement: The most common solution is to replace the faulty fuel pump with a new one. It's best to use an OEM (Original Equipment Manufacturer) fuel pump or a reputable aftermarket brand. This is a straightforward repair that can usually be handled by a qualified mechanic.
• Fuel Pump Relay: In some cases, the issue might be with the fuel pump relay rather than the pump itself. Replacing the relay is a much cheaper and easier fix. It's worth checking the relay before replacing the entire fuel pump.
• Fuel Filter: A clogged fuel filter can also restrict fuel flow and cause similar symptoms. Replacing the fuel filter regularly as part of your maintenance schedule can help prevent fuel pump issues. Make sure to check your owner's manual for the recommended replacement interval. This is a preventative measure.

If you suspect a fuel pump issue, it's important to address it promptly. A failing fuel pump can leave you stranded and potentially damage other engine components. Don't ignore symptoms like difficulty starting or stalling. Get your car inspected by a mechanic to diagnose the problem and determine the best course of action.

3. Valve Spring Recall (Potential)

While not specific to the 2016 model year, some early production FA20 engines were subject to a valve spring recall. The issue was that some valve springs were prone to fracturing, which could lead to engine damage. It's important to check if your car was affected by this recall and, if so, ensure that the repair has been performed. This is a critical safety issue.

Solutions:

• Check VIN: The easiest way to check if your car is affected is to enter your VIN (Vehicle Identification Number) on the Toyota or Subaru website. This will tell you if there are any outstanding recalls for your vehicle. Don't rely solely on previous owner's word; always verify yourself.
• Contact Dealership: You can also contact your local Toyota or Subaru dealership and provide them with your VIN. They can check for any outstanding recalls and schedule the repair if necessary. The recall repair is typically performed free of charge.

The valve spring recall is a serious issue that shouldn't be ignored. If your car is affected, it's crucial to get the repair done as soon as possible to prevent potential engine damage. Don't delay in checking your VIN and contacting your dealership.

4. Clutch Issues (Manual Transmissions)

For those with manual transmissions, the clutch can be a point of concern. Some owners have reported premature clutch wear, slipping, or difficulty engaging gears. This can be due to a number of factors, including driving style, modifications, and the quality of the clutch components. Aggressive driving habits will significantly reduce clutch life.

Solutions:

• Clutch Replacement: The most common solution for a worn or slipping clutch is to replace it with a new one. There are many aftermarket clutch kits available, ranging from OEM replacements to performance-oriented options. Choose a clutch that suits your driving style and power goals.
• Clutch Adjustment: In some cases, clutch issues can be resolved with a simple adjustment. The clutch cable or hydraulic system may need to be adjusted to ensure proper engagement and disengagement. This is a relatively simple procedure that can be done by a mechanic.
• Pilot Bearing/Throwout Bearing: When replacing the clutch, it's always a good idea to replace the pilot bearing and throwout bearing as well. These components can wear out over time and cause noise or vibration. Replacing them along with the clutch will ensure that everything is working smoothly.

Clutch issues can be frustrating, especially if you enjoy spirited driving. Regular maintenance and proper driving techniques can help extend the life of your clutch. Avoid riding the clutch, and downshift smoothly. If you experience any signs of clutch problems, address them promptly to prevent further damage.
