In some cases, these issues may require a software update or, in more severe situations, a complete transmission replacement. Recognizing these potential engine and transmission problems can help owners take proactive steps to maintain their vehicles and address issues before they escalate. Regular maintenance, careful monitoring of engine performance, and prompt attention to any unusual symptoms are essential for ensuring the long-term reliability of the 2020 Subaru Ascent.

Common Engine Issues

Okay, let's break down the most common engine issues in the 2020 Ascent. Knowing these can help you spot problems early and save you a headache later.

Excessive Oil Consumption

Excessive oil consumption is a big one. Some Ascent owners find themselves adding oil way more often than they should – like, between oil changes. This isn't normal and can point to some underlying issues. To tackle excessive oil consumption in your 2020 Subaru Ascent, start by monitoring your oil levels regularly. Keep a log of how much oil you're adding and how frequently you need to add it. This record can be valuable when discussing the issue with a mechanic. Use high-quality engine oil that meets Subaru's specifications, as this can sometimes help reduce oil consumption. Ensure that the oil filter is also of good quality and is properly installed.

Check for any visible oil leaks around the engine. Look for oil spots under your car where you park, and inspect the engine bay for any signs of oil seepage. Common areas for leaks include the valve cover gaskets, oil pan gasket, and front crankshaft seal. If you find any leaks, have them addressed promptly to prevent further oil loss and potential engine damage. Consider performing a compression test to assess the condition of your piston rings and cylinders. Low compression can indicate worn piston rings, which can lead to increased oil consumption. A leak-down test can also help pinpoint the source of compression loss.

If you suspect that your Ascent is consuming too much oil, consult with a certified mechanic. They can perform a thorough inspection of the engine and conduct diagnostic tests to identify the root cause of the problem. They may recommend specific repairs or maintenance procedures to address the issue. Keep detailed records of all maintenance and repairs related to oil consumption. This documentation can be helpful if you need to make a warranty claim or seek further assistance from Subaru. In some cases, excessive oil consumption may be a known issue covered by a technical service bulletin (TSB) or extended warranty. Check with your Subaru dealer to see if any such programs apply to your vehicle.

Turbocharger Problems

The turbocharger gives the Ascent its pep, but it can also be a source of trouble. Keep an ear out for weird noises or a drop in power – those are telltale signs. Addressing turbocharger problems in your 2020 Subaru Ascent promptly is crucial to maintaining engine performance and preventing further damage. Start by regularly inspecting the turbocharger for any signs of damage or wear. Look for cracks, leaks, or unusual noises coming from the turbocharger unit. Check the air intake and exhaust connections to ensure they are tight and free from obstructions.

Ensure that the engine oil is clean and at the correct level. The turbocharger relies on clean oil for lubrication and cooling, so regular oil changes are essential. Use high-quality synthetic oil that meets Subaru's specifications. Check the air filter regularly and replace it as needed. A dirty air filter can restrict airflow to the turbocharger, causing it to work harder and potentially overheat. Inspect the vacuum and boost hoses connected to the turbocharger for any signs of cracks, leaks, or damage. Replace any damaged hoses promptly to maintain proper boost pressure.

Listen for unusual noises such as whining, screeching, or rattling coming from the turbocharger area. These noises can indicate problems with the turbocharger bearings or other internal components. If you notice any unusual noises, have the turbocharger inspected by a qualified mechanic. Monitor the engine's performance for any signs of reduced power, hesitation, or poor acceleration. These symptoms can indicate a problem with the turbocharger's ability to deliver boost pressure. Use an OBD-II scanner to check for any error codes related to the turbocharger. Common codes include those indicating overboost, underboost, or turbocharger malfunction. If you find any codes, research them and address the underlying issue promptly.

CVT Issues

The CVT (Continuously Variable Transmission) is meant to make driving smooth, but sometimes it can cause jerky movements or hesitation. Nobody wants that! Addressing CVT (Continuously Variable Transmission) issues in your 2020 Subaru Ascent promptly is crucial for maintaining smooth and reliable performance. Start by ensuring that the CVT fluid is at the correct level and in good condition. Check the fluid level according to the manufacturer's recommendations and inspect the fluid for any signs of contamination, such as discoloration or a burnt smell. Replace the CVT fluid at the recommended intervals using the specified fluid type.

Monitor the transmission for any unusual noises, such as whining, humming, or clunking, particularly during acceleration or deceleration. These noises can indicate internal problems with the CVT. Pay attention to the way the transmission shifts. If you notice any slipping, hesitation, or jerky movements during gear changes, it could indicate a problem with the CVT. Use an OBD-II scanner to check for any error codes related to the CVT. Common codes include those indicating transmission malfunction, sensor issues, or solenoid problems. If you find any codes, research them and address the underlying issue promptly.

Ensure that the battery is in good condition and properly charged. A weak battery can sometimes cause electrical issues that affect the CVT's performance. Check the wiring and connections to the CVT for any signs of damage or corrosion. Ensure that all connections are clean and secure. If you experience persistent CVT issues, consider having the transmission software updated to the latest version. Software updates can sometimes address known issues and improve overall performance. In some cases, CVT problems may be caused by a faulty valve body. The valve body controls the flow of fluid within the transmission, and a malfunctioning valve body can lead to shifting problems. A qualified mechanic can diagnose and replace the valve body if necessary.
