2010 CHEVROLET HHR Fuel/propulsion System Problems

Car is leaking gas on left rear side. Corrosion and rust due to fuel line.

Gas lines rusted out after purchase.

Gas line rusted and leaking. Gas everywhere, strong odor, highly flammable. Under inspection at the Chevy dealer in Highland Twp. No warning lights were on.

Loss of power while driving 35mph and service traction light along with airbags light keeps showing at random times

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.

Fuel leak coming from rear wheel area on drivers side of the vehicle

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.

Fuel line leaking, driver side, forward of rear wheel. A very dangerous and common problem, one more of the many similar complaints on HHR-COBALT build platform spanning multiple years. This vehicle has only 60,000 miles.

The Fuel Lines needed to be replaced because gasoline was leaking from the lines. Zaabs Full Service Auto Repair of Bloomington, IL 61701 at 711 E. Lincoln Street replaced the Fuel Lines. We noticed a bad fuel/gasoline smell and finally saw it leaking. No warnings other than the smell. We took the vehicle 2010 Chevrolet HHR LT into Zaabs for diagnosis and replacement. We leave on a busy street and a fire or explosion could have easily happened due to people tossing cigarettes. Problem appeared in January 2023.

Gas is pouring onto the driveway on the left rear side when the vehicle is running

I smelled a strong odor of gas behind the right rear wheel of my 2010 Chevy HHR. Two different mechanics verified that the fuel lines had rusted through and need to replace. The first mechanic said that the car was unsafe to drive, and that he was not qualified to replace the lines. I had the vehicle towed to a Chevy dealership would confirmed that the lines rusted through. Google search states the cost to replace the fuel lines including labor will be around $1,034. The dealership is charging me $1,754! During my Google search, I saw that many other owners of Chevy HHRs have had the same issues. I wish for Chevy to reimburse me the expense to replace the fuel lines.

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.

From drivers side rear, fuel line rusted thru the axlefuel leaking Dealer replaced rusted fuel line from the good line tat firewall to the nylon hosed at the fuel tank. Cost 850.00

Fuel line leak at drivers side rear wheel well. Same leak that has been reported by others.

Fuel lines have corroded causing fuel to leak. Located at rear wheel of driver's side near exhaust pipe.

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 get flagged down where it has caught fire to my car. Luckily I put it out before it did any permanent damage. But it is not safe for sure.

My 2020 HHR (which I utilize while in Florida) developed a fuel leak on the driver side just in front of the rear tire. This fuel leak is right alongside the exhaust system which created a very unsafe scenario that could have easily resulted in an explosion and / or fire while driving this vehicle. I did some research and it appears that vehicles like mine are all experiencing a similar problem. I took my car to the Chevy dealer and it cost me $940 to fix this problem. With so many owners of similar vehicles having the exact same problem I believe this should have been covered under a General Motors recall and those who had to pay to get this fixed should be reimbursed. I have attached a copy of the receipt for the work done by the Chevy dealer for your informtion. I did notice that an investigation has been underway to determine if GM should recall vehicles for this problem. Had I been driving on the highway and not realized there was a gasoline leak right by the exhauset pipe it could have been a very tragic situation for me and my family. Thank you for looking into this and please let me feel free to contact me if you have any questions, etc.

Near 110,000 miles on my 2010 HHR SS I began noticing a gasoline smell and leaks under the car, and the engine was sputtering and nearly conking out under acceleration. The repair shop diagnosed it as a rusted and leaking fuel line under left rear seat, and a failed high pressure fuel pump probably due to the fuel leak. Fuel lines were replaced. Cost was too high to replace the HP fuel pump at this time.

Leaking fuel tank and lines. Very hazardous smell and liquid performance of vehicle won't start.

The fuel lines are corroded and leaking from several areas. The cost to replace all the fuel lines is $1000.00 . I cant sell it, trade it in, or drive it in this condition as even a minor fender bender could ignite the fuel and cause the car to explode with me inside. Cliffords car care center is a AAA recommended service center has inspected and confirmed the defective fuel lines. Parts are in high demand as thousands of HHR and Cobalt owners are having the same problem with corroded, leaking fuel lines. I have to wait 3 to 10 days to receive the parts. I have owned many cars and my last car I owned for 21 yrs and none have ever had a problem with leaking and corroded fuel lines. This is a known defect as hundreds of thousands of HHR and Cobalt owners have already reported this issue and an investigation is currently underway. A recall is needed and I should be refunded the cost of this repair.

THE CONTACT OWNS A 2010 CHEVROLET HHR. THE CONTACT STATED WHILE DRIVING AT AN UNDISCLOSED SPEED, HE DETECTED A STRONG FUEL ODOR INSIDE THE VEHICLE. THE FUEL ODOR WAS ALSO DETECTED WHEN THE VEHICLE WAS PARKED HOWEVER, THERE WAS NO VISIBLE FUEL LEAK ON THE GROUND. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THERE WAS A FUEL LINE LEAK NEAR THE REAR DRIVER'S SIDE TIRE THAT HAD RUSTED FUEL LINES CAUSED BY AN ENCLOSED NYLON BLOCK THAT SUPPORTED THE FUEL LINES. THE VEHICLE WAS NOT YET REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 151,000.

SUSPICION OF A FUEL LEAK WAS NOTICED BY OUR NOSES ABOUT A MONTH AGO. VISUALLY CONFIRMED 10-22-20 VIA VISUAL INSPECTION AFTER FUEL POOLS DEVELOPED AFTER VEHICLE USE AND PARKING IN GARAGE. APPEARS TO BE THE FUEL RETURN LINE, TOP LINE, NEAR THE LEFT REAR WHEEL IN THE AREA WHERE THERE IS HEAT SHIELDING ON THE LINES. I HAD THOUGHT THAT A FLEX FUEL VEHICLE WOULD HAVE HAD EXTREMELY CORROSION RESISTANT FUEL LINE MATERIAL. APPARENTLY NOT. A PERCEIVED VALUE AT TIME OF PURCHASE FROM THE NEW CAR DEALER DOESN'T EXIST. THERE IS A LOSS OF FUEL ECONOMY, AND AN INCREASED RISK TO THE VEHICLE AND GARAGE AND ATTACHED HOME. THERE IS ALSO THE OFFENSIVE FUMES. REDUCED VALUE OF THE AUTO AND REPAIR/REPLACEMENT EXPENSE THAT WILL BE SIGNIFICANT. LEAKING FUEL ALSO APPEARS TO HAVE ACCELERATED CORROSION OF OTHER MATERIALS IN THE AREA IT AFFECTS.

THERE IS A LARGE AMOUNT OF BUILT UP CONDENSATION AROUND THE CORROSION AND HE SAID THAT IF IT IS NOT ALREADY LEAKING FUEL, IT WILL BE SOON.

DISCOVERED ACTIVE FUEL LINE LEAK NEAR REAR DRIVER SIDE WHEEL OF VEHICLE WHEN PARKING VEHICLE. LEAK WOULD BE MOST ACTIVE AFTER MOVING THE CAR AND SEEMED TO EVENTUALLY STOP WHILE CAR WAS PARKED. CONTACTED DEALERSHIP. DEALERSHIP CONFIRMED LEAK AND REPLACED PORTIONS OF FUEL AND EVAPORATOR LINES AT MY COST TO THE TUNE OF APPROXIMATELY $450 PARTS AND $450 LABOR. I MENTIONED THIS SHOULD BE SEEN AS A CONSUMER SAFETY ISSUE. THEY SAID THEY CHECKED RECALLS. A WEEK LATER I NOTED A SAFETY AGENCY PROBE IN TO 2008-2009 HHR AND 2008-2010 COBALT. THIS COULD POTENTIALLY EXPAND THE MODEL YEARS FOR HHR TO THE SAME MODEL YEARS AS THE COBALT. NOTE: IN THE VIN, ENTERED INCORRECT...THE ALPHANUMERIC BEFORE X SHOWS AS 8 BUT SHOULD APPEAR AS B.

THE FUEL LINE RUSTED OUT IN FRONT OF DRIVERS SIDE REAR TIRE, SPRAYING A FINE STREAM OF GAS WHEN UNDER PRESSURE. I UNDERSTAND THIS IS A COMMON PROBLEM WITH HHR'S, LUCKILY, I CAUGHT IT EARLY COMPARED TO OTHERS. VEHICLE HAD JUST OVER 100,000 MILES AT THE TIME, AND HAS BEEN VERY WELL TAKEN CARE OF.

Mileage: 102,000

FUEL LINES ON THESE VEHICLES ARE EXPOSED WHICH HAS CAUSED RUSTING AND THE LINES BREAK. VEHICLE IS LEAKING GAS AND ONLY THE DEALER CARRIES THE PART

CAR ONLY HAS 54,168 MILES. CHECK ENGINE LIGHT APPEARED 4 MONTHS AGO. I HAVE TAKEN IT TO A NUMBER OF MECHANICS AS WELL A DEALER BUT NO ONE CAN SEEM TO FIGURE OUT WHAT THE CAUSE OF IT IS. GROSSINGER CHEVY KEPT IT FOR 1 DAY CLAIMS TO NOT FIND ANYTHING BUT LIGHT STILL ON. TREMENDOUSLY CONCERNING.

SHORTLY BEFORE CHRISTMAS (2015) WE BAGAN TO SMELL FUEL FROM THE REAR DRIVER'S SIDE OF OUR 2010 HHR. THERE DID NOT APPEAR TO BE ANY LEAKING GAS; HOWEVER, WE TOOK THE CAR TO THE DEALER FOR PROPER DIAGNOSIS. THE DEALER DETERMINED THE FUEL LINES HAD RUSTED THROUGH. WHEN WE TOOK THE CAR HOME TO DECIDE OUR NEXT ACTION, WE DISCOVERED IT WAS NOW LEAKING A SIGNIFICANT AMOUNT OF FUEL, AND PROMPTLY BROUGHT THE VEHICLE BACK FOR FULL REPAIR. THE CAR WAS 5 YEARS OLD. EVERYONE I HAVE SPOKEN WITH SINCE HAS NEVER HEARD OF RUSTED FUEL LINES ON A 5 YEAR OLD VEHICLE. I WROTE GM'S EXECUTIVE OFFICE, AND THEY SIMPLY STATED THAT IT WAS DUE TO ENVIRONMENTAL CONDITIONS. I LIVE IN FLORIDA, BUT DO NOT LIVE DIRECTLY ON OR NEAR THE OCEAN. I ALSO DO NOT PARK THE CAR AT OR NEAR THE OCEAN ON ANY KIND OF REGULAR BASIS. THIS CAR ALSO NEVER DRIVES IN SNOW. IF ENVIRONMENTAL CONDITIONS CAUSED THE FUEL LINES TO GO BAD, EVERY CAR IN FLORIDA WOULD HAVE THEIR FUEL LINES REPLACED EVERY FIVE YEARS, AND THIS IS SIMPLY NOT THE CASE. THE DISTINCTION IS THAT FUEL LINES DO NOT RUST THROUGH ON VEHICLES OF THIS AGE. THERE ARE NUMEROUS MODEL YEARS OF THE HHR REPORTING THE EXACT SAME ISSUE IN NUMEROUS STATES ALL OVER THE USA; THUS, THIS IS NOT A LOCALIZED ENVIRONMENTAL ISSUE. FAULTY DESIGN AND/OR MATERIALS IS CAUSING THESE FUEL LINES TO PREMATURELY RUST OUT AT THE JOINTS. ALMOST ALL OF THE REPORTS OF THIS ISSUE OCCUR BEFORE FIVE YEARS OF AGE FOR THE VEHICLE. IF CORVETTE'S WERE HAVING THEIR FUEL LINES RUST OUT WITHIN 5 YEARS, THERE WOULD BE A RECALL; HOWEVER, AS THE HHR IS DISCONTINUED, NOTHING HAS BEEN INVESTED INTO RESEARCHING THIS INHERENT VICE. BY THE TIME WE ACTUALLY HAD THE REPAIR DONE ON OUR HHR, IT WAS ACTUALLY LEAKING A SIGNIFICANT AMOUNT OF GAS, AND IT EASILY COULD HAVE IGNITED AND KILLED OUR FAMILY. APPARENTLY SOMEONE HAS TO DIE, FOR A RECALL TO BE ISSUED.
