    I was constantly smelling a strong odor of gas coming from the inside/outside of my 2015 Chevy Tahoe. When I purchased the vehicle in 10/23 everything appeared fine. I researched the internet to determine what the problem could be & found dozens of similar situations. People saying the fuel line rubs the undercarriage of the vehicle causing a pin hole size in the fuel line causing it to leak gas. Currently my vehicle is in the shop and the problem is TBD.

CARR service convinced me it was “great”, as now my…
