Reliability and Common Issues

Reliability is a crucial factor when considering any car, and the 2015 Lexus RC 350 generally holds up well. Lexus has a reputation for building dependable vehicles, and the RC 350 is no exception. However, like any car, it's not immune to potential issues. Here are some common problems reported by owners:

  • Carbon Buildup: Direct injection engines, like the 2GR-FSE, can be prone to carbon buildup on the intake valves. This can lead to reduced performance, rough idling, and decreased fuel economy. Regular maintenance, such as intake valve cleaning, can help prevent this issue.
  • Oxygen Sensor Failure: Some owners have reported issues with oxygen sensors failing prematurely. This can trigger the check engine light and affect fuel economy. Replacing the faulty sensor typically resolves the issue.
  • Water Pump Leakage: The water pump is a critical component of the cooling system, and some RC 350 owners have experienced leaks. If you notice coolant loss or overheating, it's essential to have the water pump inspected.
  • Fuel Injector Issues: While the D-4S system is advanced, it can sometimes experience issues with fuel injectors. Symptoms can include rough idling, misfires, and decreased fuel economy. Cleaning or replacing the injectors may be necessary.
  • Transmission Problems: Although less common, some owners have reported issues with the automatic transmission, such as rough shifting or slipping. Regular transmission fluid changes can help prevent these problems.

Despite these potential issues, the 2015 Lexus RC 350 remains a reliable car overall. Regular maintenance and addressing any issues promptly can help ensure many years of trouble-free driving. It's also a good idea to check online forums and resources for more information and to stay informed about any potential problems specific to this model year.

Maintenance and Care

To keep your 2015 Lexus RC 350 running smoothly, regular maintenance is essential. Here's a breakdown of the key maintenance items:

  • Oil Changes: Change the engine oil and filter every 5,000 to 7,500 miles, depending on driving conditions. Using the recommended oil type and viscosity is crucial for engine health.
  • Fluid Checks: Regularly check and top off all fluids, including coolant, brake fluid, power steering fluid, and windshield washer fluid.
  • Air Filter Replacement: Replace the engine air filter every 15,000 to 30,000 miles to ensure optimal engine performance.
  • Spark Plug Replacement: Replace the spark plugs every 60,000 to 100,000 miles to maintain proper ignition and fuel efficiency.
  • Brake Service: Inspect the brakes regularly and replace brake pads and rotors as needed. Brake fluid should be flushed every two to three years.
  • Tire Rotation and Alignment: Rotate the tires every 5,000 to 7,500 miles to promote even wear. Have the alignment checked and adjusted as needed to ensure proper handling and tire life.
  • Transmission Service: Change the transmission fluid every 60,000 miles to keep the transmission shifting smoothly.
