General Motors (GM) has issued a new 2022 duramax recall for certain 2022 GMC Sierra HD and Chevrolet Silverado HD vehicles equipped with the 6.6L V8 L5P turbodiesel Duramax engine. This recall stems from a concerning issue linked to the Engine Control Module (ECM) within affected vehicles.

  • Change Air Cooler (CAC) low efficiency (DTC P026A)

    What are the symptoms of a faulty engine control module?

    Engine Control Module (ECM) or Engine Control Unit (ECU) failure can cause a variety of symptoms that compromise vehicle performance and safety. These symptoms differ based on the severity of the issue, your vehicle’s make and model, and the ECM failure. Here are some common symptoms:

    • Check Engine Light On
    • Poor Engine Performance
    • Stalling or Misfiring
    • Fuel Efficiency Problems
    • Transmission Issues

    To preserve your safety, see a certified mechanic immediately if you notice ECM malfunction.

    What should I do if my truck has GMC or Chevy ECM problems but isn’t being recalled? 

    Certainly, if your GMC or Chevy truck is experiencing ECM (Engine Control Module) problems but is not part of a recall, you should consider the following steps:

    • Present your Vehicle for Repairs: Reach out to your authorized GMC or Chevrolet dealership and present your vehicle for warranty repairs. Ensure that all repairs are properly and well documented on the repair orders. Keep copies of your repair orders.
    • Seek Legal Advice: Consult with an attorney who specializes in lemon law cases to assess whether your situation qualifies for legal action under your state’s lemon laws. They can guide you on the specific legal requirements and potential remedies available to you.
    • Document the Problem: Maintain records of all communication with the dealership or manufacturer, repair attempts, and associated expenses. Comprehensive documentation is crucial for legal proceedings.
    • Check for Technical Service Bulletins (TSBs): Investigate whether there are any relevant TSBs addressing the ECM issue for your vehicle. This information can be useful in legal discussions.
    • Review Warranty Coverage: Examine your vehicle’s warranty, including any extended warranties you may have purchased. Warranty coverage can impact your legal options and the potential compensation you may receive.

    While addressing ECM problems through legal channels can be a complex and time-consuming process, it may be necessary to protect your rights and interests if your vehicle does not fall under a recall but continues to experience significant defects.

    Legal action under the lemon laws can provide potential remedies and compensation for affected consumers.
