2021 Chevrolet Trailblazer Fuel system Problems

“On 2/21/25 when I turn on vehicle the engine light came on. I checked for the code and it was P1467 for the Evap Purge Pump. I checked for the gas pump cover and didn't see anything damaged and closed it tight but engine light still on. I feel the gas or engine smell is also coming through the inside of car when fan is turned on and not safe health wise.”

“I have brought my car into the dealership over the last few years at least 6 times for the same issues. Currently there are two codes coming up as permanent on my car which is for the Evaporative Emission System Flow and Brake Booster Hydraulics performance. I drive my child of three every day and the number of times my check engine light comes on and goes into reduced engine power is not okay nor safe.”

“IN January my fuel gage stopped working , unable to know how much gas I had. The fuel pump and floater needed to be replaced If fuel was not getting to the engine the vehicle would stop working causing a possible accident with other drivers . I did not use this vehicle for many days until a mechanic cleared for useage . It cost me $320.00 of my own money to fix this for safety concerns. As of today 1/22/25 I has been fixed by A-Plus in North Fort Myers.”

“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. …”

“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.”
