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.

Took to mechanic due to strong fuel smell coming from engine area. Mechanic said not safe to drive - fuel rail leaking and must be replaced - vehicle could catch fire or explode! I drive grandchildren in this vehicle and was shook up! Vehicle towed to GM dealer who said I was 3400 miles passed my warranty but they would start work on my $3k repair. I-??m outraged that GM cares so little about this known issue from the GM bulletin PIP 5765 which was published 11/18/20. All this time they have known about faulty and dangerous part but only send recalls for minor issues like possible faulty tire jack.

3 times in the last year while we were driving the acceleration wen very high like from 50 to all of a sudden went up to about 80. I had to stand on the brake and try to pull over. Still accelerating I put it in park and shut it off. When you restart it it drive fine again. This has happened three times and the dealership says they can't find a problem. We are stuck driving a death trap. Please help. They wanna charge diagnosis everything I take it in. Then they say they can't find nothing. Now I am finding others that have had same issue and dealership says there is no problem. This has got to be destroying the engine reving at such high speeds.

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.
