Common Issues and How to Troubleshoot

Alright, let's get down to the nitty-gritty. What are some common issues you might encounter with your 2024 Lexus IS 350 F Sport? And more importantly, how do you troubleshoot them? From the engine to the suspension, we'll cover the most frequent problems and how to approach them. One of the most common issues reported by Lexus IS owners is related to the engine. The 3.5-liter V6 engine is generally reliable, but some owners have reported issues like oil leaks, misfires, and decreased performance. These problems can often be traced back to things like faulty spark plugs, worn-out ignition coils, or issues with the fuel injectors. To troubleshoot these, start by checking the engine for any visible leaks. Then, use an OBD-II scanner to read any error codes. Error codes can give you a clear indication of what is wrong. For instance, a code related to misfires could indicate a bad spark plug or coil. Another issue, which is more frequently reported, is problems with the suspension system, especially in the F Sport trim. The sport-tuned suspension offers superior handling, but it can also be more susceptible to wear and tear. Over time, you might notice issues like clunking noises, uneven tire wear, or a harsh ride. These symptoms could be caused by worn-out shocks, struts, or suspension bushings. If you notice these symptoms, a visual inspection of your car can help you identify any problems. Look for any signs of damage or wear on the suspension components. Another crucial area to watch is the brakes. Brake pads and rotors wear out over time, especially with the high-performance driving the IS 350 F Sport is capable of. Check your brake pads regularly for wear, and listen for any grinding noises that could indicate a problem. Other common issues include problems with the electrical system, especially the infotainment system and the various sensors. The infotainment system in these cars can occasionally glitch, and some sensors might fail or malfunction. These are less critical than engine or suspension problems, but can be annoying. This is why regular check-ups are essential, even if you are not experiencing any apparent problems.

Engine Problems

Let's go into detail about engine problems. As mentioned earlier, the 3.5-liter V6 engine in the 2024 Lexus IS 350 F Sport is known for its reliability, but issues can still arise. Oil leaks can be caused by worn-out seals, gaskets, or even a damaged oil pan. Check for oil stains under the car and inspect the engine for any visible leaks. Misfires are another common problem, often caused by faulty spark plugs or ignition coils. Symptoms include rough idling, reduced power, and the check engine light flashing. Using an OBD-II scanner to read the error codes can quickly identify the problem. You will likely want to replace the spark plugs and coils. Also, decreased performance can be caused by various issues, including a clogged air filter, a dirty throttle body, or problems with the fuel injectors. A clogged air filter can restrict airflow, leading to reduced power. A dirty throttle body can affect how the engine responds to the throttle. Fuel injectors that are not working properly can cause all sorts of problems. These can be cleaned or even replaced.

Suspension Woes

The F Sport trim features a sport-tuned suspension, which provides enhanced handling but may require more maintenance. Clunking noises could indicate worn-out shocks, struts, or suspension bushings. This usually indicates that components need to be replaced. Uneven tire wear can be a sign of alignment issues or worn suspension components. Make sure you check your tires and how they are wearing. A harsh ride could be due to worn-out shocks or struts. Inspecting the shocks and struts for leaks or damage is vital.

Brake System Failures

Brakes are one of the most important safety systems in your car. Worn brake pads are a common issue and can lead to reduced braking performance and grinding noises. Inspect the brake pads regularly for wear and tear. Grinding noises when braking usually indicate worn-out brake pads or rotors. This requires immediate attention to avoid any serious problems.

Electrical Glitches

Electrical problems are pretty annoying. Infotainment system glitches can range from software bugs to hardware issues. Try resetting the system. You might even have to reset it to its factory settings. Sensor failures can affect various systems, from the engine to the safety features. Use an OBD-II scanner to identify any sensor-related error codes.
