Leaky fuel injectors, on the other hand, can cause excessive fuel consumption, a strong fuel smell, and potentially damage to the catalytic converter. What causes fuel injectors to malfunction? Over time, fuel injectors can become clogged with deposits from the fuel itself. Low-quality fuel can exacerbate this problem. Leaks can occur due to wear and tear on the injector seals or damage to the injector body. If you suspect you're having fuel injector problems, there are a few things you can do. First, try using a high-quality fuel injector cleaner additive in your fuel tank. This can sometimes help dissolve minor deposits and improve injector performance. However, if the problem persists, it's best to have a mechanic inspect the fuel injectors. They can use specialized equipment to test the injectors and determine if they need to be cleaned or replaced. In some cases, simply cleaning the injectors can restore their performance. However, if they're severely clogged or leaking, replacement is usually the best option. Maintaining a clean fuel system is essential for the longevity of your engine. Using high-quality fuel and periodically using a fuel injector cleaner can help prevent fuel injector problems from developing in the first place.

4. Water Pump Failure

Another potential issue to be aware of is water pump failure. The water pump is a critical component of the engine's cooling system. It circulates coolant throughout the engine, preventing it from overheating. If the water pump fails, the engine can quickly overheat, leading to serious damage. Some owners of the 2018 Toyota RAV4 LE AWD have reported premature water pump failure. What are the signs of a failing water pump? One of the most obvious signs is a coolant leak. You might notice a puddle of coolant under your car, or you might see coolant dripping from the water pump itself.
