Consumer Description

I have noticed a recurring issue during the colder months where there is a strong gas smell inside the cabin, and I have also observed fuel dripping into the engine compartment. This issue seems to occur primarily in winter conditions. I was surprised to find that there has been no official recall or service bulletin addressing this concern, especially given the potential safety implications.
