Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Heavy fumes are present inside and outside the vehicle after the fuel tank is filled and persists until the fuel gauge reads 7/8 of a tank. Have not determined what is causing the fumes other than it only happens when the fuel tank is full. Current solution is to not fill up the fuel tank completely.”
