Common Problems and Symptoms

Now, let's get into some of the issues you might encounter with your 2020 Subaru Ascent SC Premier ESC. The most obvious symptom is the ESC warning light illuminating on your dashboard. This can be accompanied by other warning lights as well, like the ABS light or the traction control light. But what could trigger these lights? Here are some common culprits:

• Sensor Failures: The ESC system relies heavily on sensors. If one of these sensors fails, the system might not function correctly. Common sensor failures include wheel speed sensors, yaw rate sensors, and steering angle sensors.
• ABS Issues: Because the ESC system works closely with the ABS, any problems with the ABS can also trigger ESC warnings. This could be due to a faulty ABS module, problems with the brake lines, or issues with the brake pads.
• Software Glitches: As with any modern vehicle, software plays a huge role. Sometimes, a software glitch can cause the ESC system to malfunction. This can often be resolved with a software update.
• Wheel Alignment Issues: Believe it or not, a misaligned wheel can also trigger the ESC light. The system relies on the steering angle sensor to determine your vehicle's direction, so if the wheels are not aligned correctly, the system can get confused.
• Tire Pressure Problems: Make sure the tires have the correct pressure because it can also affect the ESC system. Low tire pressure can also make the ESC system not function correctly. Check your tires regularly to make sure that they are in good condition.

Diagnostic Steps and Troubleshooting

If the ESC light pops up on your 2020 Subaru Ascent SC Premier, don't panic! Here's a basic troubleshooting guide:

1. Check for Obvious Issues: Start with the easy stuff. Make sure your tires are properly inflated and check for any visible damage to the wheels or tires.
2. Inspect the Sensors: Look for any obvious damage to the wheel speed sensors. These sensors are located near the wheels and can sometimes get damaged by road debris.
3. Use an OBD-II Scanner: An OBD-II (On-Board Diagnostics II) scanner is a handy tool that can read diagnostic trouble codes (DTCs) from your car's computer. This can help pinpoint the exact cause of the ESC issue. The scanner will tell you which sensor is failing or if there are any other problems.
4. Check Brake Fluid: Make sure the brake fluid level is correct. Low brake fluid can sometimes trigger the ESC light.
5. Professional Inspection: If you can't identify the issue, it's time to take your Ascent to a qualified mechanic. They have the specialized tools and expertise to diagnose and repair the problem correctly.
