Transmission & drivetrain Vehicle recall #07V453000 · 2007 · 1,497 vehicles
What's wrong: On certain sport utility vehicles equipped with the 4.6l engine and 6r transmission, the bolt securing the transmission oil cooler line fittings at the transmission May not have been sufficiently torqued during vehicle assembly.

Why it matters: If leaking transmission fluid contacts the catalytic converter, it May pose a risk of fire.
