Is There a Chevy Malibu Reduced Engine Power Recall?

Currently, there isn’t a universal recall addressing the “Reduced Engine Power” issue across all Chevy Malibu models.

However, some specific recalls and legal actions have been associated with this problem for certain model years.

For example, a recall affected over 300,000 Chevy Malibu models from 2013–2015 to resolve an engine power reduction issue via a software update.

Additionally, some 2018–2022 models have reported reduced engine power caused by issues with the Charge Air Cooler (CAC) outlet tube.

If you’re dealing with reduced engine power in your Malibu, check for any active recalls or warranty coverage for your vehicle.

A GM-certified technician can also help diagnose and resolve the issue effectively.

What Causes the Chevy Malibu Reduced Engine Power Problem?

The “Reduced Engine Power” problem in Chevy Malibu models can stem from several underlying causes. Here are the most common ones:

1. Faulty Accelerator Pedal Position Sensor: Malfunctioning sensors may send incorrect signals to the engine control unit (ECU), limiting engine power.
2. Throttle Body Issues: A dirty or damaged throttle body can restrict airflow to the engine, causing power loss.
3. Mass Airflow (MAF) Sensor Problems: If the MAF sensor fails, it may provide incorrect air measurement data to the ECU, affecting engine performance.
4. Fuel System Issues: Problems with components like the fuel pump or injectors can lead to insufficient fuel delivery, reducing power.
5. Ignition System Defects: Faulty spark plugs, or ignition coils can cause misfires, resulting in power loss.
6. Electrical System Complications: Wiring or connector problems can disrupt signals to essential components, leading to reduced engine power.
7. Sensor Failures: Malfunctioning sensors, such as the throttle position or engine temperature sensor, can compromise engine performance.
8. Airflow Issues: A clogged air filter can restrict airflow, leading to inefficient combustion and reduced power.

Prompt diagnosis and repair of these issues can help restore your vehicle’s performance. Consult a professional mechanic to identify and address the specific problem.

What Are the Symptoms of Reduced Engine Power?

When your Malibu experiences reduced engine power, you might notice the following symptoms:

• Dashboard Warning Light: The “Engine Power Reduced” message may appear.
• Hesitant or Jerky Acceleration: Difficulty accelerating smoothly.
• Stalling or Starting Issues: Trouble starting the engine or frequent stalling.
• Decreased Fuel Efficiency: A noticeable drop in gas mileage.
• Sluggish Engine Performance: The car may feel less responsive.
• Misfires or Vibrations: Engine misfires or vibrations during acceleration.
• Higher Emissions: Increased exhaust emissions.
• Unusual Noises: Odd sounds coming from the engine.

If you encounter these symptoms, have a mechanic evaluate your vehicle promptly to prevent further complications.

Has Chevy Released Any Malibu Reduced Engine Power Recalls or Service Bulletins?

Yes, Chevrolet has issued several service bulletins and other communications regarding the “Reduced Engine Power” issue in Malibu models. Here are some key examples:
