US highway agency expands probe into GM pickups, SUVs over engine failures

The National Highway Traffic Safety Administration expanded its investigation into General Motors pickups and SUVs after reports that V-8 engines continue to fail despite a previous recall remedy. The probe covers nearly one million vehicles. Separately, federal regulators opened an engineering analysis into more than 1.1 million GM vehicles, including electric models, following reports of unexpected power assist loss in the eBoost brake-by-wire system. One 2024 Blazer EV driver claimed they steered into a concrete curb to avoid a collision during a brake failure.

  1. NHTSA expands GM engine probe as repaired V8s continue to fail

    The National Highway Traffic Safety Administration expanded its investigation into General Motors pickups and SUVs after reports that V-8 engines continue to fail despite a previous recall remedy. The probe covers nearly one million vehicles. Separately, federal regulators opened an engineering analysis into more than 1.1 million GM vehicles, including electric models, following reports of unexpected power assist loss in the eBoost brake-by-wire system. One 2024 Blazer EV driver claimed they steered into a concrete curb to avoid a collision during a brake failure.

    Why it matters

    Recurring engine failures in the 6.2-liter L87 V8 suggest previous corporate fixes were inadequate. The simultaneous brake-by-wire investigation indicates broader reliability concerns across both combustion and electric platforms.

    What is confirmed

    • The NHTSA is investigating nearly one million GM pickups and SUVs with V-8 engines.
    • Regulators are examining whether a previous recall remedy for GM engines was sufficient.
    • Over 1.1 million GM vehicles, including EVs, are under investigation for eBoost brake-by-wire system issues.

    Still unconfirmed

    • A 2024 Blazer EV driver steered into a concrete curb to avoid a catastrophic intersection collision due to brake issues.
    • The 6.2-liter L87 V8 engine is the specific model under federal scrutiny for failures after repair.

    What to watch next

    • NHTSA determination on the adequacy of the V8 engine recall remedy
    • Findings from the eBoost brake-by-wire engineering analysis
    • Potential new recalls for the 2024 Blazer EV

  2. US highway agency expands probe into GM pickups, SUVs over engine failures

    The US National Highway Traffic Safety Administration (NHTSA) has expanded its investigation into General Motors (GM) pickups and SUVs due to reports of engine failures. The probe now includes nearly one million vehicles, specifically those with V-8 engines, after receiving complaints of engine failures despite a previous recall remedy. The NHTSA is examining whether the recall fix was sufficient to address the issue.

    Why it matters

    This investigation is significant because engine failures can lead to sudden loss of power, increasing the risk of accidents. The affected vehicles include various GM pickup truck and SUV models. The NHTSA's action follows reports of continued engine problems even after GM implemented a recall remedy. This raises concerns about the effectiveness of GM's fix and the potential safety risks to drivers.

    What is confirmed

    • The NHTSA is investigating nearly one million GM vehicles with V-8 engines over engine failure reports.
    • The investigation includes various GM pickup truck and SUV models.
    • Engine failures can lead to sudden loss of power, increasing the risk of accidents.

    What to watch next

    • The NHTSA's determination on whether GM's recall remedy was sufficient
    • The number of vehicles ultimately recalled or repaired
    • Potential actions by GM to address the engine failure issue
