The fuel lines have corroded causing a hazardous gas leak by the fuel tank which could have caused a severe fire and or explosion while driving. I noticed a gas smell in the vehicle when parked and upon further investigation recognized a gas drip by the the corroded fuel lines and gas traveling down the lines from the leak. Thankfully I noticed this before a fire would have occurred. Had I had a disability with no sense of smell or covid19 and no sense of smell this issue could have gone unnoticed possibly causing a fatal hazard should the car have caught on fire while driving. My garage could have also caught fire. Stainless steel should not rust and this is clearly a dangerous defect by the manufacturer. This matter should be addressed and a recall addressed.

Fuel leak, . fuel leakage from car, will no longer start. Bad fuel pump, bad fuel lines. Why is there no recall for this obvious design flaw?

First time plastic fuel line cracked at fuel pump and whole fuel pump assembly needed replaced. Now there is a fuel line that has corroded. It is costing $1030 at the Chevy dealer to fix this line. Fuel is leaking behind the driver door in front of the rear tire. When lifted fuel appears to be coming from above fuel tank.

The first time I smelled gas and found the gas line leaking from a bracket holding the gas lines was about 2 years ago (2018), cost $100 dollars to get fixed. Now there is another gas leak farther back near the gas tank coming from another bracket. I have never had another vehicle give this many problems with gas line leaks. I drive the car almost every day, it rarely sits for more than 2 days in a row

There is a fuel leak in front of the rear driver's side tire. This leak is worse while the vehicle is running. I have taken the vehicle to a GM dealership, and they told me it was not something they would pay to repair (after I paid the diagnostic fee).
