What owners say about the fuel/propulsion system
Verbatim from NHTSA complaints, newest first
“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.”
“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. ZAABS REPAIR INVOICE #5922 DATED 03/06/2023 = PAID IN FULL $337.81. ZAABS PHONE (309) 386-1999.”
“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.”
