If the National Highway Traffic Safety Administration (NHTSA) believes there is a safety-related defect in a group of cars, it reserves the right to open an investigation.

These investigations are often sparked by warranty claims and consumer complaints online.

  1. An investigation will look into 10 complaints of total loss of power while driving the 2020-2021 Porsche Taycan.

    The luxury EV is equipped with two batteries, an 800-volt for the heavy lifting and a 12-volt auxillary battery. The National Highway Traffic Safety Administration (NHTSA) wants to know if a loss of charge in the 12V battery can deactivate the car's entire electrical system. A sudden loss of power is a killer for any vehicle, but feels particularly bad in a car that relies solely on electricity.

  2. Porsche 911 cars with the GT1 engine might suddenly lose all their coolant and shut down, just don't expect a recall for it.

    The National Highway Traffic Safety Administration (NHTSA) which opened an investigation last year says Porsche has fixed the problem.

    "Porsche submitted reports suggesting a problem with the adhesive used to attach coolant pipes in about 6,800 model year 2007-2008 Porsche 911 cars. The problem was fixed by the supplier and according to NHTSA, the initial problem wasn't as bad as first thought."

    NHTSA said no injuries or crashes were caused by coolant leaks and since they only order recalls for safety-related issues, it's no surprise the investigation was closed. Disappointing? Yes. Predictable? Also yes.

  3. The National Highway Traffic Safety Administration (NHTSA) is going to take a look at the 2001-2007 Porsche 911 to find out why it's GT1 engine is suddenly losing all its coolant and shutting down.

    I should say allegedly, but try telling this guy that it's not real:

    "One Porsche owner said their vehicle took on a mind of its own when hot antifreeze leaked and covered the road and rear tires. The vehicle went out of control and traveled off the road."

    The most likely source for a sudden leak that fast would be a coolant hose fitting disconnecting from the engine block.
