I just recently started getting the smell of gas inside and under hood.Anyone else notice this with their TB? Time for a trip to dealer.

Could be a gasket leak right before the catalytic converter, definitely have the dealer check it out.

There have been a few reports of the high pressure mechanical pump leaking.

Be safe, the Trailblazer DI fuel pump operates at 5076 psi, very dangerous if it's spraying out. Let us know what they find.

Have my 2021 Trailblazer at dealer for gas smell repairs.Had to wait until after Holidays.Right now waiting for parts to arrive. Looks like I am not the only one with this problem with the 2021 1.3L. Gm service bulletin PIP5765 covers a leak in fuelrail. Will update on actual parts replaced when done.

5000 psi is more than enough pressure to find a leak somewhere. Let us know what part they replace so we can all keep an eye on it.

Just picked up Trailblazer from dealer.Took almost 4 weeks to get parts,it was the fuelrail leaking gas.

I'm gonna report fuel leak to NHSTA just incase it is a larger problem than we know about.
