FUEL LINE LEAKING IN TWO PLACES, IN THE REAR AND IN THE FRONT. COMPLETELY RUSTED OUT. MY CAR ONLY HAS 60,800 MILES ON IT. TYPE OF CAR IS A 2008 CHEVY HHR LT 2.4. GAS IS LEAKING ON THE GROUND AND A STRONG SMELL OF GAS IS EMITTED FROM THE CAR. THIS IS VERY DANGEROUS BECAUSE THE CAR COULD CATCH FIRE. I DID NOT THINK THIS WOULD HAPPEN TO MY CAR WITH SO FEW MILES ON THE CAR. I DID NOT KNOW THERE WAS A PROBLEM AND DROVE THE CAR 130 MILES AWAY FROM HOME TO MY DAD'S FUNERAL. THEN I HAD TO DRIVE IT BACK BECAUSE TH E TOW WOULD HAVE BEEN $700. THE MECHANIC WHO INSPECTED THE CAR. BUDDY LLOYD'S LAKEVIEW AUTOMOTIVE AT 4757 SANG RUN ROAD IN MCENRY, MD 21541, SAID IT WOULD COST ABOUT $2,000 TO FIX BECAUSE OF THE EXTENT OF THE CORROSION AND THE CHAEP MATERIALS USED. IN ADDITION, THE FUEL LINES ARE LOCATED UNDERNEATH OTHER MAJOR PARTS AND WOULD HAVE TO BE TAKEN OFF TO GET TO THE FUEL LINES. THE MECHANIC SAID AT ANY MOMENT IF I HIT A BUMP THAT THE GAS COULD EMPTY THE TANK AND POSSIBLY CATCH FIRE!

Corrosion of the metal fuel lines underneath the vehicle towards the rear and in the vicinity of the left rear wheel well.
Gas leak has started on the driver side in front of the rear tire.
Purchased vehicle in Sep 2021. After 4 months of purchase, muffler became loose from exhaust after hitting a pothole on highway and, having a mechanical background, I repaired the exhaust by placing a solid stainless steel exhaust sleeve around the weak area and tac welding it. Within a month, I began to smell a rich fuel odor after every trip. I jacked up vehicle and found a fuel leak within insulated area just left of exhaust. I also located another small exhaust leak and repaired it as best as possible with an exhaust wrap, then took it to an exhaust repair shop. I was told fuel leak had to be repaired before exhaust repairs could be done. Mechanic said HHRs we're well known for fuel line corrosion due to poor design and eventually leaking. He said he has turned away many HHRs and Cobalts for this problem over the last 2-3 years.

My Fuel line is pouring gas out . The gas fumes are filling the cabin of the car waiting for a repair.
Fuel line leak.
Fuel lines leaking in front of drivers side rear tire. Lines run inside of a channel that has a protective wrap over them, but is very close to part of the exhaust pipe. Fuel line had corroded inside of protective wrap. Only leaks when the engine is running and fuel system under pressure. Fuel could have hit hot exhaust pipe and caused a fire or explosion. Apparently this is a common problem with the Chevy HHR with multiple cases having already been reported. Had the car repair at our local Chevy dealer. Cost of removing and replacing the fuel lines was $1,307.00. The only indications of the problem was the smell of fuel near the rear tire and a puddle of fuel under the car when engine was shut off. Frame cross member was also wet from fuel shooting out of end of protective wrap.
Fuel lines leaking under left rear of 2008 HHR. According to Google internet investigations this seems to be a problem in the design and placement of insulation material over the fuel line. I almost had a explosive concern, not knowing where the smell of fuel was coming from, a alert gentleman smoking a cigarette counseled me on a dripping fuel on the parking lot. He said smokers will throw their cigarette down and unintentionally possibly causing a fire/explosion.

My gas lines are leaking. It appears that several other owners of HHR's are having the same issue.
gas leaking..over left rear wheel well where the silver insulation is ..line has rusted thru the insulation is because the exhaust runs close to that side of the vehicle but unfortunately there in no way or takes too long for moisture to evaporate poor design ....
Metal fuel lines rusted thru under the left rear door area where they are wrapped in insulation with no ability tor drain or dry out. The car is unsafe to drive I need to have it fixed now. I will try to safe defective parts. Fuel leak under the car near exhaust and almost undrivable, safety factor is obvious and currently under investigation. Will be calling dealer today. Noticed delayed start and heavy gas smell and then saw puddle under car. Removed insulation wrap and found heavy deposit of road dirt and rust.
FUEL LINE SUDDENLY SPRUNG A LEAK. I NOTICED IT AFTER DRIVING ON THE HIGHWAY. THERE WAS GASOLINE DRIPPING AFTER I PARKED AND LOOKED.
