Thread: Cabin fuel smell

  1. #1

    Cabin fuel smell

    '11 M56 with 140K miles....

    Lately have noticed a strong fuel smell in cabin coming through HVAC from engine bay, mostly when starting or stopping engine. Can also be smelled outside of car.

    Dealer superficially inspected and couldn't recreate or find any leaks. Proposing, expensively to go fishing, now to remove top cover intake plenum to inspect fuel rail. Car is otherwise running fine.

    Any ideas or similar experience?

    there is a fuel rail recall on the M56 which had a loose bolt. take to your dealer immediately, this could cause a fire if fuel leaks. ITB12-010a Safety Recall Campaign

    Any codes? Check engine light ever on? The rail, bad injector, bad plug or coil, etc. It is unburnt fuel for some cause.

    Dealer told me my car didn't fall under that recall campaign.

    Also, no performance issues or check lights yet.

    May have to bite the bullet on diagnostics....

    I would, leaking fuel is nothing to trifle with all it takes is a spark or a hot exhaust manifold and boom !

    Make sure your insurance coverage is paid up and be prepared to bail at the first sign of flames.

    But seriously, breathing those fumes can be harmful to your health, not to mention leaking fuel is never a good thing.

    Ask the dealer why it didn't fall under the recall campaign. I think all 2011-12 QX and M's were affected. I'm assuming you went to an Infiniti dealership, you didn't specify.

    Checked out that new recall. Apparently it does not re-cover cars already fixed (including mine) in a previous, similar 2012 recall campaign.

    Could still be the issue and will have them re check the fix.
