    When it comes to the 911 Carrera, the 911 Targa, or the 718 Boxster, there's an indisputable fact – those cars are hot.

    As in, their engines can leak gas, spark a flame, and turn into one of the world's most expensive bonfires. What did you think I meant?

    Porsche is recalling about 4,100 cars because the fuel collection pipes' fastening screws can shear off and lead to gas leaks. While there haven't been any fires yet, Porsche knows it's only a matter of time. The recall affects 37 engine types:

    "The recalled replacement engines are 2.0L, 2.5L, 3.0L LP and 3.0L HP engines with part numbers 9A2100920 X, 9A2100925 X, 9A2100927AX, 9A2100930 X and 9A2100930AX."

    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.

    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.
