Common Mitsubishi Lancer 2015 Engine Problems

Alright, let's talk about some of the issues you might encounter with the Lancer's engine. No engine is perfect, and these are some of the most common issues reported by owners and mechanics.

Oil Consumption

Some 2015 Lancers, especially those with higher mileage, might experience increased oil consumption. This means the engine is burning oil, and you'll need to top it off more frequently. This issue can often be more noticeable during aggressive driving. Keep a close eye on your oil level and check it regularly. Low oil levels can cause serious engine damage. The best way to prevent this is by regular maintenance and oil changes. Consider using a slightly thicker oil if oil consumption is excessive. Regular oil checks are essential. This helps to catch any issues early before causing damage. Using the correct oil type and viscosity is crucial for minimizing oil consumption. Addressing this promptly can prevent significant engine problems. Keeping your oil topped off is a great preventative.

Timing Chain Issues

While not as common as some other problems, some owners have reported issues with the timing chain. This can manifest as a rattling noise, especially during cold starts. The timing chain is critical for the engine's operation, so it's important to address this issue promptly. This often happens because of worn components. The timing chain connects the crankshaft to the camshaft, making it essential. If the timing chain fails, it can cause catastrophic engine damage. Regular inspections and maintenance can help catch issues early. These inspections can prevent severe failures. Replacement is often required if there are signs of wear. Make sure you are paying attention to potential timing chain problems.

CVT Transmission Problems

If your Lancer has a CVT (Continuously Variable Transmission), you might encounter issues related to it. While not directly an engine problem, the CVT is closely linked to engine performance and can affect the driving experience. Common symptoms include slipping, shuddering, or complete failure. CVT problems can be quite costly to repair. The CVT relies on the engine for power, making the engine's performance dependent on the transmission. Regular maintenance is key to minimizing CVT problems. Proper fluid changes and regular inspections are important. Ignoring these problems can lead to significant damage. Addressing these issues can save you from a major repair bill. Remember to service your CVT regularly to keep it running smoothly.

Spark Plug Issues

Over time, spark plugs can wear out, leading to misfires, rough idling, and decreased fuel efficiency. Replacing spark plugs at the recommended intervals can help maintain optimal engine performance. Regular spark plug maintenance is essential. Worn spark plugs can affect engine performance and fuel economy. Misfires and rough idling are often signs that spark plugs need attention. Check and replace spark plugs according to the service schedule. Following a schedule helps maintain your engine's performance.
