1. Engine and Powertrain Concerns

The engine and powertrain are crucial components of your 4Runner's performance. Here's a look at some common issues in the 2016 model:

1.1. Engine Knocking and Noise

Engine knocking, also known as pinging, can be a concerning issue. It often sounds like a metallic tapping or rattling, particularly under acceleration. This problem can be due to various factors, including:

• Low-Quality Fuel: Using fuel with a lower octane rating than recommended can lead to pre-ignition, causing knocking.
• Carbon Buildup: Carbon deposits within the engine can increase compression, potentially leading to knocking.
• Spark Plug Issues: Faulty spark plugs can also cause misfires, contributing to knocking.

Solutions:

• Use the recommended octane fuel grade as per the owner's manual. High-quality fuel can prevent knocking and ensure optimal engine performance.
• Have the engine decarbonized by a professional mechanic to remove carbon deposits.
• Regularly inspect and replace spark plugs according to the maintenance schedule. Using the correct spark plugs will ensure proper combustion.
