2020 Subaru Ascent: Common Engine Problems & Solutions

Hey guys! Let's dive into some of the engine issues that 2020 Subaru Ascent owners have been reporting. The Ascent is a great SUV, but like any vehicle, it's not immune to problems. Knowing what to look for can help you keep your Ascent running smoothly and avoid costly repairs.

Understanding the 2020 Subaru Ascent Engine

The 2020 Subaru Ascent is equipped with a 2.4-liter turbocharged four-cylinder engine, which is designed to deliver a balance of power and efficiency. This engine, while generally reliable, has faced its share of challenges. Let's get into the nitty-gritty of what you need to know about the 2020 Subaru Ascent engine.

Common Engine Issues

Several common engine issues have been reported by 2020 Subaru Ascent owners. These include problems with the turbocharger, oil consumption, and the continuously variable transmission (CVT). Addressing these issues promptly can prevent more significant damage and ensure your vehicle remains reliable.

Turbocharger Problems: Some owners have reported issues with the turbocharger, such as unusual noises or a decrease in performance. The turbocharger is critical for boosting the engine's power, and any malfunction can lead to a noticeable drop in acceleration and overall engine performance. Regular inspections and maintenance can help identify and resolve these issues early.
Excessive Oil Consumption: Another common complaint is excessive oil consumption. Some Ascent owners have found that their vehicles require frequent oil top-ups between scheduled oil changes. Monitoring your oil levels regularly and using the recommended oil type can help mitigate this issue. If the problem persists, it's essential to consult a mechanic to check for leaks or other underlying causes.
Continuously Variable Transmission (CVT) Issues: The CVT is responsible for smooth gear transitions, but some owners have experienced issues like hesitation or jerky movements. CVT problems can affect the overall driving experience and potentially lead to more severe transmission damage if not addressed promptly. Regular maintenance, including fluid checks and changes, can help keep the CVT in good condition.

Symptoms to Watch For

Being aware of the symptoms of engine problems is crucial for early detection and timely repair. Here are some signs that your 2020 Subaru Ascent might be experiencing engine issues:

Unusual Engine Noises: Keep an ear out for any unusual noises coming from the engine, such as knocking, hissing, or whining sounds. These could indicate problems with the turbocharger, belts, or other engine components.
Decreased Performance: Noticeable drops in acceleration, power, or fuel efficiency can be signs of engine trouble. If your Ascent feels sluggish or isn't performing as it should, it's worth investigating.
Check Engine Light: The check engine light is your car's way of telling you something is wrong. Don't ignore it! Have the code read by a mechanic to diagnose the issue.
Excessive Oil Consumption: If you find yourself needing to add oil more frequently than usual, it could indicate an oil leak or internal engine problem.

Potential Causes

Understanding the potential causes of these engine issues can help you take preventative measures. Here are some common factors that can contribute to engine problems in the 2020 Subaru Ascent:

Manufacturing Defects: In some cases, manufacturing defects can lead to premature engine wear or failure. While these are rare, they can occur and may require warranty repairs.
Poor Maintenance: Neglecting regular maintenance, such as oil changes and filter replacements, can accelerate engine wear and lead to problems down the road. Following the recommended maintenance schedule is crucial for keeping your engine in good condition.
Driving Habits: Aggressive driving habits, such as frequent hard acceleration and braking, can put extra stress on the engine and its components. Driving more conservatively can help prolong the life of your engine.
Quality of Fuel and Oil: Using low-quality fuel or oil can also contribute to engine problems. Always use the recommended fuel grade and oil type specified in your owner's manual.

How to Troubleshoot Engine Problems

When you encounter engine issues, troubleshooting can help you identify the root cause and determine the best course of action. Here's a step-by-step guide to troubleshooting engine problems in your 2020 Subaru Ascent.

Check the Basics: Start by checking the basics, such as the oil level, coolant level, and battery voltage. Ensure that all fluids are at the correct levels and the battery is in good condition.
Read the Error Codes: Use an OBD-II scanner to read any error codes stored in the vehicle's computer. These codes can provide valuable clues about the nature of the problem.
Inspect for Leaks: Look for any signs of leaks, such as oil or coolant, under the vehicle or around the engine. Leaks can indicate damaged seals, gaskets, or hoses.
Listen for Unusual Noises: Pay attention to any unusual noises coming from the engine, such as knocking, hissing, or whining sounds. These noises can help pinpoint the source of the problem.
Test Drive: Perform a test drive to observe how the engine performs under different conditions. Note any issues with acceleration, shifting, or overall performance.

DIY vs. Professional Repair

Deciding whether to tackle engine repairs yourself or seek professional help depends on your mechanical skills and the complexity of the problem. Here's a breakdown to help you make the right choice.
