Short answer: The most common problems with the Chevy Equinox are throttle body issues, fuel system problems, mass airflow sensor (MAF) problems, charge air inlet pipe damage, and ignition system failures.

These issues happen because various components in the engine and fuel system can wear out or become dirty over time, leading to inefficiencies and performance problems.

Continue reading to learn more about how to prevent and address these issues in your Chevy Equinox.

#1: Throttle Body Issues

• What it is: The throttle body controls the amount of air that flows into the engine, which is crucial for the air-fuel mixture needed for combustion.
• Potential causes: Carbon buildup; Mechanical wear; Electrical issues with the throttle position sensor
• Symptoms: Reduced engine power; Rough idling; Stalling; Check engine light
• Potential fix: To fix throttle body issues, you can clean the throttle body or replace the throttle body or throttle position sensor.

#2: Fuel System Problems

• What it is: The fuel system includes components like the fuel pump, fuel filter, and fuel injectors, which deliver fuel to the engine.
• Potential causes: Clogged fuel filter; Failing fuel pump; Dirty or malfunctioning fuel injectors
• Symptoms: Reduced engine power; Difficulty starting the engine; Engine misfires; Poor fuel economy
• Potential fix: To fix fuel system problems, you can replace the fuel filter, repair or replace the fuel pump, and clean or replace the fuel injectors.

#3: Mass Airflow Sensor (MAF) Defects

• What it is: The MAF sensor measures the amount of air entering the engine, which helps the engine control unit (ECU) adjust the air-fuel mixture.
• Potential causes: Dirt or debris on the sensor; Electrical issues; Sensor failure
• Symptoms: Reduced engine power; Rough idling; Hesitation or stalling; Check engine light
• Potential fix: To fix MAF sensor defects, you can clean the MAF sensor or replace it.

#4: Charge Air Inlet Pipe Damage

• What it is: The charge air inlet pipe directs air from the turbocharger to the engine.
• Potential causes: Physical damage to the pipe; Leaks or cracks
• Symptoms: Reduced engine power; Whistling or hissing noises; Poor acceleration
• Potential fix: To fix charge air inlet pipe damage, you should inspect and replace the damaged pipe.

#5: Ignition System Failures

• What it is: The ignition system includes components like spark plugs and ignition coils, which are responsible for igniting the air-fuel mixture in the engine.
• Potential causes: Worn spark plugs; Faulty ignition coils; Electrical issues
• Symptoms: Reduced engine power; Engine misfires; Rough idling; Difficulty starting the engine
• Potential fix: To fix ignition system failures, you can replace the spark plugs, replace the ignition coils, and inspect and repair electrical connections.

Is There a Chevy Equinox Reduced Engine Power Recall?

No, there isn’t a specific recall for the Reduced Engine Power issue in the Chevy Equinox, but there are known issues and service bulletins addressing this problem.

For instance, GM has issued technical service bulletins (TSBs) for the 2018-2022 and 2023-2025 models, identifying potential causes like issues with the Charge Air Cooler (CAC) outlet tube or the Charge Air Inlet Pipe.

According to GM bulletin number PIP5927B, reduced engine power is just one of the symptoms that can appear in the Chevy Equinox.

Affected models of the 2023, 2024, and 2025 Chevy Equinox may also trigger several Diagnostic Trouble Codes (DTCs), including:

• P0237: Manifold Absolute Pressure (MAP) sensor A, turbocharger (TC) circuit low input
• P0101: Mass Air Flow (MAF) Sensor Performance
• P1101: Intake Air Flow System Performance
• P0299: Engine Underboost

This problem impacts the sole engine option for the 2023 through 2025 Chevy Equinox, which is the turbocharged 1.5L I4 LSD gasoline engine producing 175 horsepower.

If low engine power and one or more of the above DTCs are present, dealer service personnel should inspect the Charge Air Inlet Pipe and apply any necessary recall fixes.

Is There a Fix for the Equinox Reduced Engine Power Problems?

Yes, there are several possible solutions for the “Reduced Engine Power” issue in the Chevy Equinox. Here are some common fixes:

1. Clean or Replace the Throttle Body: A dirty or faulty throttle body can limit airflow, leading to reduced power. Cleaning it with a throttle body cleaner might resolve the issue.
2. Check the Fuel System: Problems like a clogged fuel filter or a failing fuel pump can also cause reduced engine power. Inspecting and replacing these components if necessary, can help.
3. Inspect the Mass Airflow (MAF) Sensor: A malfunctioning MAF sensor can cause incorrect air-fuel mixture readings, leading to power loss. Cleaning or replacing the MAF sensor might fix the problem.
4. Examine the Charge Air Inlet Pipe: For newer models (2023-2025), GM has identified issues with the Charge Air Inlet Pipe. If this pipe is damaged, it can cause low engine power. Replacing the damaged pipe can resolve the issue.
5. Check the Ignition System: Faulty ignition coils or spark plugs can lead to misfires and reduced engine power. Inspecting and replacing these components as needed can improve performance.

If you’re experiencing this issue, it’s advisable to have your vehicle checked by a professional mechanic who can diagnose and address the specific cause.
