Very strong gas smells coming from under the hood. After driving a few miles, fumes enter the passenger compartment. Had to stop parking it in our garage for fear of a fire before I could get it into the dealer. I've been told it's a fuel leak associated with the fuel rail system. I'm 20 days past my warranty and only at 29,000 miles. It's a nearly $2000 fix. GM was aware of the problem in 2021 as there is a service bulletin for this item. I should have been notified in 2021 that there was a possible problem which could lead to a fire or explosion.

What owners say
I had a smell of gasoline inside and under hood of 2021 Trailblazer LT 1.3l. Took to Chevrolet dealer.Confirmed gas odor. Gas was leaking from fuel rail.Sevice manager said it was pouring out. Found out GM has Service bulliten for this PIP5765 that covers both Chevy Trailblazer with 1.3l and Buick Encore GX with 1.3l motors. This has been a scary situation considering gas fumes could have caught fire.

- What is wrong
- On certain sport utility vehicles, a fuel filter fitting can become disconnected. If this were to occur while attempting to start the engine, a no-start condition would result and fuel would be pumped out the fuel filter onto the ground.
- Risk
- If the fitting becomes disconnected while the vehicle is in motion, the engine would stop due to inadequate fuel supply and cause a loss of power steering assist. If an ignition source were present, fuel leakage from a disconnected fuel filter fitting could result in a fire.
- Remedy
- Dealers will replace the fuel filter quick connect retainers. Owner notification began september 20, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1‑800‑222‑1020.
