Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“After driving the smell of fuel comes from the engine by the drivers door. I contacted GM and my vehicle does not show on the list of this known recall. They passed me to a local dealership which stated my vehicle is not one that falls under the recall and admitted they had fixed others with similar issues. This is appalling that a manufacture can assist some customers but not all. I will never purchase another GM vehicle again.”

NHTSA complaint #10694087, filed 2015-03, 110,600 miles

“Noticed a strong gas odor in the garage. I couldn't see any leakage until I started (pressurized the fuel lines). I noticed a braided area of the fuel lines that cross over each other, touching, which caused them to rub together creating a pin hole in each line. When pressurized, they shoot fuel out. Luckily, they didn't cause a fire as we had just finished a 700 mile trip with our grand kids. The shop wants $805 to replace the lines. This is a safety hazard that should be recalled. Very dangerous!!!”

“Supply and return fuel lines have a flexible, shielded section at the frontmost end ... The hoses cross and therefore rub against one another ... Top hose became worn through, causing copious quantities of fuel to be pumped out onto the cross member and roadway ... Extreme fire hazard.”

NHTSA complaint #10585768, filed 2014-04, 115,000 miles

“I noticed a strong smell of gasoline and upon inspection found a significant fuel leak under the driver's door. A closer look reveals that there are 2 rubber fuel lines that touch and have worn through each other, causing them to leak fuel. This is all within inches of the exhaust system. Any reasonable person would assume that this is a fire hazard! This is an obvious design flaw that could easily be avoided.”
