criticalFUEL/PROPULSION SYSTEM
Filed: Aug 2025

The fuel pump filter housing is the cause of the malfunction, it is available for inspection upon request. When I am driving I intermittently lose fuel delivery altogether and my car comes to a halt for a second until I press on the gas pedal to get the car going again, this puts myself and other people in danger if my car randomly stops while I am driving around others and causes crash risk.

Fuel pump started going out. My brothers vehicle also started going out too in the same vehicle as this. It's clearly a wide issue.
