Fuel supply lines near drivers rear wheel started leaking while engine is running. Strong odors of gasoline and significant puddle of fuel under the car after a short time of running. It appears to be excessive corrosion of the line near the supports, heat shield. This leak seams to be near the exhaust system of the car so could be a fire safety issue. Inside of a garage or other closed area, these fumes could lead to possible explosion from an ignitions source

I would like to report of a fuel line leak in the fuel lines from the fuel tank to the engine. The lines are leaking due to corrosion caused by the manufacturer encasing the lines in, I think heat resistant tape to protect from the nearby exhaust, and a plastic type clamp that holds and separates the fuel and brake lines. The vehicle does not have to be running for fuel to leak as it will leak if just the key is on due to the electric fuel pump. I have read many complaints of this online and understand that there is an investigation into this safety problem ( fire hazard due to proximity of exhaust). This is a manufacture design / engineering problem and should be recalled by them. This is a very expensive repair ( $ $1,200 if only fuel, more if brake lines need replacing ), that not all people will be able to afford and will therefore ( like myself ) continue to drive their vehicles until they can have it repaired or worst try to attempt to repair it themselves ( not something I would suggest ). I think everybody is at risk if vehicles are driving around leaking fuel ( and maybe losing brakes next ) because people can not afford to fix them. I hope tragedy doesn't strike first ( as seems to be the case nowadays ) before people are motivated to take action. Attached are pictures showing the lines dry and wet. The tape and clamp are visible in picture, showing where corrosion and leaking occurred.

Fuel line leaking very heavily. I have read that some of these vehicles were recalled but mine was NOT. The fuel is leaking at a very heavy drip drip drip rate from the rear driver side and causing fuel puddles. This is directly near the exhaust system. I-??m very surprised as I also have an identical 2008 Chevy HHR with similar but lighter leak. I-??m surprised that this is not a recall given a fuel leak. It should also be an EPA issue. Why would the car use coated brake lines but no stainless or coated lines for fuel when they run so closely to the exhaust system? This should easily be a safety/environmental recall related issue.

i began noticing a fuel smell at the rear of my car late last week. upon inspection, I noticed that my fuel lines were corroded below some heat shield fabric ahead of the left rear wheel. when I went online, I noticed a recent recall for this exact problem, except, it did not include my model year.my complaint is that this car is identical, with regards to the fuel delivery and that GM should include it in its recall. I have not attempted to contact any dealership as of yet, because entering my vin, does not produce a positive result on this site or others I have tried.

Drove car approximately 10 miles and parked in driveway. Immediately smelled gas upon exiting car and saw puddle forming in front of left rear tire. Could feel the spot where leak was coming from and see the drops as they fell. I crawled underneath and took these pictures. The corrosion was at one of the brackets right before a piece of heat shield. I then peeled back part of the heat wrap and found that it was very wet from the leaking gas as was the frame and other parts in the vicinity of the leak. The leak only occurred of course when the fuel lines were pressurized. Approximately 15 minutes after the car was shut off the drips of fuel would stop.

Because of poor design the fuel lines on my HHR rusted and developed a leak spraying fuel over the bottom of the vehicle. We noticed the oder of gasoline when we parked. It is a 2011 HHR

Strong odor of gasoline near vehicle and inside vehicle. Odor persistently got worse over time, and was most noticeable when vehicle was parked. Vehicle repaired on January 11, 2021, however odor started approximately a year earlier, but only after filling tank with gas. Fuel tank broken and leaking.

Gas leak under car drivers side near the front of the rear tire. Replaced fuel lines. Puddles of gasoline underneath car and strong smell of fumes.

- Plymouth, MA, USA

My fuel line just in front of the drivers side rear tire has started leaking really bad. There is a strong smell of gasoline plus visible gasoline leaking on the ground. Very dangerous. After a search, it appears that this problem is being investigated by NHTSA and GM. Add my 2011 HHR to the list of fuel lines that has started leaking.

Intense gas smell and slight ignition delay. No gas smell until after it is running.. I understand I should not even drive vehicle to repair shop because of a fire danger. Many more complaints exactly like mind. This is a huge safety risk because of firze. I question why there was never a recall. We certainly don't have a year to wait for an investigation.

My 2011 Chevy HHR like many others I've learned from checking online is leaking gas near the rear passenger side door. This is a design flaw and is very dangerous. Why is there not a recall on this are you waiting for one of these cars to burst in flames and someone to be killed before GM is made responsible to fix the defect. I don't have hundreds of dollars to repair this.and even when GM is held responsible they do as little as possible and they don't really address the problem. I also have a 2004 Chevy Impala and there is a recall on that for the ignition, by the time they notified me my ignition switch had malfunctioned and they won't fix that. There fix is to alter the key so there isn't so much pressure on the switch. That does me no good since the car is sitting in my hard and it is dead because the switch malfunctioned and I can't afford to get it fixed.. when they sell a car they make a lot of money kn it but they don't stand behind their product. And no one makes them do so. But as soon as someone is killed then they do damage control and you hear all this bull, we didn't know, we didn't think it was that bad, and we are not responsible. I know this rant will do no good but I couldn't sleep at night if I knew I was the one responsible for things like this. Thanks

Car was struggling to start, when it did, it wouldn't go over 20mph, went to store, came out, it would start. Had it towed to the shop, engine crack and from that cracking it broke other stuff. I owe 3700. On the car and to fix it is $3200 sadly I do T have the money. No care, no way to get to work. Car was sitting in parking lot of our local save a lot.

I was driving a freeway speeds when the engine suddenly went into limp home mode. I received the following dash indications - service ESC, traction off, reduced engine power. Upon further inspection we found a failed accelerator position sensor and we had the following trouble codes stored in the computer: P2135 Chevrolet - throttle/pedal position sensor/switch 'a'/'B' voltage correlation replaced the accelerator position sensor and gas pedal assembly, at this point the car seems fine. I have the failed part.
