Lexus RC F (2014–present)

The Lexus RC F is a high-performance variant of the RC, unveiled at the 2014 North American International Auto Show. It became available for purchase in the United States in November 2014 as a 2015 model and was slated for release in Japan during the second half of 2014.

The RC F is powered by a 5.0 L (4,969 cc) 2UR-GSE V8 engine, which operates in the Atkinson cycle at cruising speeds. It delivers a maximum output of 473 PS (467 bhp; 348 kW) at 7,100 rpm and 389 lb-ft (527 N⋅m) of torque between 4,800 and 5,600 rpm. The engine is paired with an Aisin AW-built Toyota AA80E 8-speed transmission. The RC F features Brembo four-wheel power-assisted disc brakes with anti-lock braking (ABS), electronic brake-force distribution (EBD), and brake assist (BA), along with 255/35R19 front and 275/35R19 rear tires.

Common Issues Reported By Owners

The 2018 Lexus RC F is a high-performance luxury sports coupe with a powerful V8 engine, aggressive styling, and advanced features. It’s known for its sharp handling, refined interior, and reliable build quality. However, like any performance vehicle, there are some common issues that owners have reported. Below is an overview of the potential problems and maintenance tips for the 2018 Lexus RC F.

Common Issues with the 2018 Lexus RC F

1. Transmission Hesitation

• Issue: Some owners report slight hesitation or rough shifting, particularly at lower speeds, with the 8-speed automatic transmission.
• Symptoms: Hesitation during acceleration, rough shifts, or delayed engagement of gears.
• Solution: Perform a transmission software update or fluid replacement. If the issue persists, further inspection of the transmission components may be needed.

2. Brake Wear

• Issue: Due to the high-performance nature of the RC F, brake pads and rotors may wear faster than those in a non-performance vehicle.
• Symptoms: Squeaking, grinding, or reduced braking power.
• Solution: Regularly inspect brake pads and rotors, especially if driving the car aggressively. Replace the pads and rotors with OEM parts when necessary.

3. Infotainment System Glitches

• Issue: The Lexus Enform infotainment system in the RC F may experience occasional glitches such as slow responses, connectivity issues, or system crashes.
• Symptoms: Frozen screens, lagging controls, or difficulty pairing with Bluetooth or Apple CarPlay.
• Solution: Perform software updates through the dealer or via over-the-air updates. If issues persist, a factory reset or system component replacement may be required.

4. Electrical System Issues

• Issue: Some owners have experienced issues with the electrical system, including malfunctioning lights, sensors, or electrical accessories.
• Symptoms: Warning lights, inoperative sensors, or malfunctioning electronics.
• Solution: Check for loose connections or blown fuses. Software updates and recalibrating sensors may also help address some issues.

5. Oil Leaks

• Issue: There have been reports of oil leaks from the valve cover gasket or oil cooler lines in some 2018 RC F models.
• Symptoms: Visible oil spots under the car, low oil levels, or engine oil warning lights.
• Solution: Inspect the valve cover gaskets and oil cooler lines for signs of leakage. If leaks are detected, replace the affected components.

6. Suspension Noises

• Issue: The sport-tuned suspension can develop issues over time, particularly with components like struts or bushings, leading to clunking or squeaking noises.
• Symptoms: Unusual noises when driving over bumps or during tight turns.
• Solution: Inspect suspension components regularly, especially if you hear unusual noises. Replacing worn-out bushings or struts can help restore smooth ride quality.

7. Steering Wheel Vibration

• Issue: A few owners have reported steering wheel vibrations, especially at higher speeds.
• Symptoms: Steering wheel shaking or vibrating, often when driving at highway speeds.
• Solution: Check the alignment and balance of the wheels. If necessary, balance the tires or replace any tires that are unevenly worn.

8. Engine Performance Issues

• Issue: Some drivers have noticed a decrease in engine performance or power delivery, which could be due to various factors such as clogged fuel injectors, dirty air filters, or spark plug issues.
• Symptoms: Reduced acceleration, hesitation, or loss of power.
• Solution: Regularly replace the air filters and spark plugs. Consider using fuel additives to clean the fuel system if performance drops.

9. Limited Rear Seat Space

• Issue: The RC F is a two-door coupe, and while it offers rear seats, they are cramped and not ideal for adults, which some owners find impractical.
• Symptoms: Lack of legroom or tight seating for passengers in the back.
• Solution: If rear-seat comfort is important, consider using the RC F primarily as a 2-seater or opt for a different vehicle with more rear-seat space.

10. Cabin Noise

• Issue: Some drivers report that wind and road noise can be noticeable at higher speeds, especially considering the performance-oriented design of the vehicle.
• Symptoms: Noticeable cabin noise during highway driving.
• Solution: Consider adding sound-deadening materials or check the door seals for wear and tear to reduce noise levels.

Maintenance Tips for the 2018 Lexus RC F

1. Regular Oil Changes: Use high-quality synthetic oil and follow the recommended service intervals to ensure engine longevity.
2. Brake Maintenance: Due to the high-performance nature of the RC F, monitor the brake pads and rotors regularly and replace them with OEM parts to ensure optimal braking performance.
3. Transmission Fluid and Software Updates: Regularly check the transmission fluid and stay up to date with software updates to avoid shifting issues.
4. Tire Care: Ensure that tires are properly rotated, balanced, and aligned to avoid uneven wear, especially if driving aggressively.
5. Suspension Inspections: Given the sport-tuned suspension, inspect it periodically for signs of wear or damage, especially after aggressive driving or rough road conditions.
6. Battery and Electrical System: Inspect the battery regularly, especially if the car is used infrequently, and check for any electrical issues with lights or accessories.
7. Cooling System: Monitor coolant levels and perform regular maintenance on the cooling system to avoid overheating issues.
8. Infotainment Updates: Keep the infotainment system updated to avoid glitches and ensure smooth functionality with your devices.
