The contact owns a 2017 Bentley Bentayga. The contact stated that while driving at an undisclosed speed, there was an abnormally strong fuel odor detected. The vehicle was taken to the dealer where it was diagnosed that the fuel line was fractured and the fuel tank needed to be replaced. The vehicle was not repaired.

The auto start on this Bentley bentagya most of the time does not work properly, but as I AM now over 12,000 miles it has started to cause the car to call at odd times. For example coming out of a parking space the car stalled leaving me half in and half out the space. It also stalled at a traffic light 3 days ago.

Common questions
Source: NHTSA, 49 CFR 579.5Is Bentley 2055321.4 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the 2055321.4 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does 2055321.4 cover?
The manufacturer filed it against 6 model years: 2023 Bentley Bentayga, 2022 Bentley Bentayga, 2021 Bentley Bentayga, 2020 Bentley Bentayga, 2018 Bentley Bentayga, 2017 Bentley Bentayga. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
