2008 GS350 - 129k miles - 1 owner Looking for input on whether/how to proceed as this is now a multi-year problem (2019- 2021). My 2008 Lexus GS350 had the following recalls (All fuel and engine related): NHTSA CAMPAIGN ID: 18V432000; NHTSA Campaign Number: 14V647000 NHTSA CAMPAIGN ID: 09V020000; NHTSA CAMPAIGN ID: 10V309000 Before the last fuel assembly recall work was out of warranty 2019, I started experiencing an extreme fuel odor after a decline AND each time car was started (noticeable only with windows down). No warning lights, system reported no issues. Independent mechanic found a leaking fuel injector (port on that side is "clean".) (Lexus dealerships found no issues). Replaced fuel injector, no change in fuel smell, strong as ever. Neither Lexus or Independent mechanic can determine what is wrong. Pandemic happened and I only drive the car once a week to the grocery store, strong fuel smell on startup still happens. (Haven't been on any incline/declines). 5/9/21, filled gas tank, started car, made 2 stops before heading home, "Check engine, Check VSC" and a myriad of lights came up on dash. (Total of 3 startups after filling tank, lights came on after 3rd start). Code comes up - P0430 - Catalyst System Efficiency Below Threshold Bank 2 All the fuel related symptoms & issues can't be a coincidence. 2 Fuel assembly recalls, fuel smell, leaking fuel injector, continued fuel smell, now catalytic converter issue even though car is barely used in the last year.

I own a 2008 Lexus gs 450H. I recently (March 2018) had an issue with my car that I need to share with the NHTSA. When starting my car, I noticed the smell of gasoline while sitting in the driver's seat. I knew something was obviously wrong. I took my car to the nearest auto shop where they troubleshot the gasoline leak to a fuel pressure pulsation damper on the fuel rail of the engine. After doing a little research on the internet, I have discovered there have been multiple recalls for gasoline leaks in the engine bays of Lexus vehicles. I did bring my car to the dealer for the "elf" recall in 2015 which covers the fuel pressure sensor. When reading about the "9la" and the "bla" recalls, it seems that my car does not fall under the affected vehicles of these respective recalls. So we have a problem. I did have the "leaky fuel" recall for my car performed by the Lexus dealership (3 years ago) but I still ended up with an extremely dangerous and potentially fatal condition with gasoline leaking on the top of my engine. An engine's fuel rail (and the fuel rail components) is an item that should be expected to last the life of an engine without leaks. I have attached 2 pictures of my defective part as well as the invoice for the repair. I currently have possession of the defective part and would like to help in any way possible with a NHTSA investigation so this extremely dangerous condition can be addressed with a solution.
