    While operating vehicles , the smell of fresh gasoline was coming into cabin. Made left hand turn to pull over and check gas cap, as I turned the rear of my car spun around like I was on ice. Almost hit pedestrians, my rear tires soaked with gasoline…scary. Gas pouring out from real lines next to Muffler.

    Noticed gasoline dripping under the vehicle just behind the driver side rear door. Upon investigation discovered steel fuel line has corroded between a plastic support bracket and fiber heat shield. This seems to be due to a design that allows moisture and road debris (salt) to accumulate, leading to corrosion. This could lead to total loss of power to the vehicle, and poses a risk of fire while in operation or while parked.

    Strong smell of gasoline on left side of vehicle in front of rear tire. Gasoline is present when viewed from underneath. Looks like leakage is in area where 4 lines (supply/vent/brake?/brake? ) are mounted together...or certainly in that area. I do see on line that this is not a new issue with owners. Have just started the process of getting quotes on this repair.

    My fuel line is leaking like so many others. Driver side near the rear wheel well in the bracket that holds the lines to the body. I also owned a 2007 Chevy hhr that had the same issue, both started at just over 150,000 miles. While the leak on the 2007 was minor the leak one the 2010 has gotten so bad that the vehicle will no longer idle.

    Fuel line leaking right in front of rear driver side tire. Puddles up. Steady leak. And strong odor of gasoline in and outside of the car. Gets me woozy at times. It also gets on my tires and affects steering if I was parked on pavement for a while it puddles back to my rear tire. And makes me worry about a fire. Right in the back seat where a car seat would be. Because I was driving through my yard a while back and my family was burning some limbs and stuff. All at once I…
