Fuel system reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Car has developed a fuel leak once again in the rear of the vehicle. this is the second time a fuel leak has been noted. the first time the mechanic replaced a portion of the line that had corroded and was leaking fuel near the driver rear tire. now the leak is in another section of the original pipe near the fuel tank. this is poor quality and engineering.

Fuel leak coming from the Left (Drivers Side) of the vehicle in the area of the rear wheel. There was a strong odor of fuel, Fuel was observed dripping to the ground under the vehicle in front of the Left rear wheel. This condition was observed only when the vehicle was running and in park. The condition does not seem to happen when the vehicle is off and not running. No repair has been made yet , vehicle can be inspected in its current condition. This is a severe safety concern of ignition/explosion due to a fuel leak; risk of property damage or even death. This problem has not been addressed yet to a dealer or local mechanic as of yet . Failed component has not yet been inspected by GM, Police or insurance. No warning lamps or messages were illuminated on dashboard, prior to failure, vehicle did have some difficulty starting, possibly due to this problem, but it did start.

Fuel line leak. My fuel line has cracked in multiple places and needs to be replaced entirely. The leak was consistent, with a constant stream leaking out when in operation and for several minutes after stopping the engine. The odor of gasoline was strong from inside of the vehicle when in operation and large puddles of gas were visible on the ground afterwards when I first noticed the issue. My repair quote is about $500 to get the line replaced entirely.

Body clips holding fuel line causing rusting at these points. Leaking fuel from body clip in front of driver’s side rear tire. Based on caked on debris (mud like consistency), it has been happening for a while but wasn’t leaking to driveway due to disuse of the vehicle. This has commonly happened on 2008-2010 HHRs and Cobalts too.

The contact owns a 2007 Chevrolet HHR. The contact stated while her aunt was driving at an undisclosed speed, there was an abnormal gasoline odor inside the vehicle. After a visual inspection, it was discovered that there was fuel leaking from the rear of the vehicle. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. After investigating the failure, the contact related the failure to a past NHTSA investigation but was unable to provide specific information. The manufacturer was notified of the failure, and a case was filed. The failure mileage was unknown.

I HAVE A FUEL LINE LEAK NEAR THE LEFT REAR TIRE WHICH HAS BEEN HAPPENING WITH OTHER VEHICLES SUCH AS THE COBALT AND OTHER HHR'S. I TOOK IT TO A DEALER AND THEY SAID IT IS GOING TO COST ME $1500 TO REPLACE ALL THE FUEL LINES BECAUSE THEY WERE RUSTED REALLY BAD. THIS SHOULDN'T BE HAPPENING PLUS IT'S NOT VERY SAFE. THIS SHOULD BE A RECALL ITEM. MY VEHICLE ONLY HAS ~156000 MILES ON IT. THANKS

Notice a gas smell coming from the car when I would get out of the car after driving it . but could not find the source of the smell at first . Then one day I was parked on a black Asphalt payment and seen a wet spot on the payment I then looked under and seen a small wet spot on the protector where the gas line run through on the left side near the lower rear door wear it opens up I then made a call to my GM car dealer ship to see if it is under warranty or a recall but they said no recall for the Fuel lines that when i looked up if other people are having the same problem . And found over 614,000 having the same problem . Note I am waiting on the parts from my dealer so they can fix it which is over $900.00 I am paying for it .

My 2007 HHR (I also hve a 2008 with the same issue as this) was being configured with replacement front seats and after completion the mechanic/installer informed me that there was a strong gas leak on the driver's side. Upon looking at the car a very noticeable puddle of gas was on the ground. I had the car moved to my home and it is currently unable to use due to the gas leak. This is ridiculous. Everything I have read points to Chevy cheaping out and not using non-corroding metal lines or nylon and the proximity of the heat shield which traps the moisture and corrodes the fuel lines. This REALLY needs to be recalled at Chevy's expense as it is a manufacturer's error. I have no idea if a prior situation had been addressed by the previous owner (commercial computer repair shop).

THERE IS A RECALL FOR 2008-2009 HHRS FOR FUEL LINE CORROSION. I AM HAVING GAS PUDDLES AND DRIPS FROM LEAKING FUEL LINES NEAR THE LEFT REAR WHEEL WELL, NEAR THE EXHAUST PIPE AND MUFFLER. WHICH IS THE EXACT SAME ISSUE AS DESCRIBED IN THE 2008-2009 HHR RECALL. I HAVE TRIED SPEAKING WITH GMS CUSTOMER ASSISTANCE. ALL THEY DID WAS TELL ME OVER AND OVER AGAIN THAT MY HHR ISN'T INCLUDED IN THE RECALL. 🙄 I KNOW THIS...THAT'S THE PROBLEM. THE DEALERSHIP REFERRED ME TO CHEVY'S CUSTOMER ASSISTANCE...CUSTOMER ASSISTANCE KEPT PUSHING BACK THAT I NEEDED TO TALK TO THE DEALERSHIP'S CEM. NO ONE WANTS TO HELP WITH THIS SITUATION...JUST PUSHING ME TO TALK TO SOMEONE ELSE. SO THAT IS WHY I CAME HERE SO THAT SOMEONE WILL LISTEN TO THIS SAFETY CONCERN THAT THEY KNOW THEY HAVE BASED UPON FUEL LINE RECALLS FOR CERTAIN MODELS. I BELIEVE THEY NEED TO BROADEN THEIR RECALL TO INCLUDE OTHER HHRS.

I NOTICE THAT THE TANK HAS BEEN LEAKING FUEL. THIS OCCURS WHEN I FILL UP THE TANK AND/OR THE FUEL SWISHES OR MOVES AROUND. THIS HAPPENS ON THE REAR LEFT TIRE. IT SEEMS TO GET ON THE EXHAUST OR HEAT UP AND SMELL EXCESSIVE FUEL. I NOTICED THIS WHEN I WOULD PARK FOR AT LEAST 20 MINS ON A FULL TANK. I AM A FUEL TANK ENGINEER AND SEE THIS AS A POOR DESIGN POSSIBLY

FUEL LINE CORROSION AND LEAK NEAR DRIVER SIDE REAR TIRE. STARTED OUT AS FUEL VAPOR SMELL WHEN WALKING NEAR CAR. LATER DEVELOPED INTO FUEL LEAK UNDER CAR. VERY CONCERNING TO ME BECAUSE LEAK IS NEAR EXHAUST SYSTEM. EVENTUALLY HAD TO HAVE CAR TOWED (FOR SAFETY) TO REPAIR GARAGE WHERE I HAD TO PAY OVER $600 FOR ALL NEW FUEL LINES. DUE TO GM STRIKE IN 2019 AND RESULTING PARTS SHORTAGES, MY CAR WAS OUT OF SERVICE FOR 4 MONTHS. INTERNET SEARCH SHOWS THAT MANUFACTURER HAD ISOLATED THE FUEL LINES FROM THE EXHAUST COMPONENTS BY USING HIGH TEMPERATURE 'SLEEVE'; THIS SLEEVE APPARENTLY TRAPS WATER THAT CORRODES THE METAL FUEL LINES.

UNSURE OF DATE WHEN OFFICIALLY HAPPENED OR NOTICED BUT, AFTER FILLING GAS TANK UP, THERE IS A STRONG ODOR OF GASOLINE THAT PERSISTS AND PERMEATES INTO THE CAR. ODOR IS MOST NOTICEABLE WHEN DO NOT DRIVE THE CAR FREQUENTLY, ODOR GOES AWAY WHEN TANK AT 3/4 OR LESS. NO VISIBLE FUEL LEAKING, AND MECHANIC DID NOT NOTE LEAK FROM FUEL TANK.

FUEL SUPPLY AND RETURN LINES ARE RUSTING THROUGH. LEAK STARTED JUST UNDER THE DRIVERS SIDE REAR DOOR. UPON INSPECTION BOTH LINES NEED REPLACED COMPLETELY. I TOOK IT TO A MECHANIC AND HAD A PATCH PIECE PUT IN ON THE AFFECTED LINE, BUT WAS TOLD THIS IS A COMMON PROBLEM WITH THESE CARS CAUSED BY BAD DESIGN AND POOR CHOICE OF MATERIALS. THE PROBLEM WAS FIRST NOTICED WHEN CAR WAS STATIONARY AND TOOK LONGER THAN NORMAL TO START. I NOTICED THE SMELL OF GAS AND THERE WAS A VISIBLE SPOT OF GAS ON THE GROUND UNDER THE CAR.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
