“I experienced a problem that may be the same problem as the Lexus valve spring problem, or related to it. The mechanic said it was caused by a design flaw. Here is part of a letter I sent to Lexus in march 2010: I own a 2006 Lexus is350, which I had been very happy with until february 1, 2010. As I was driving to work, there was a loud noise from the engine and the dashboard lit up with warning lights. I pulled over, read the owner?s manual, and drove to a Lexus dealership. The four year old car only had about 27,000 miles on it. Unfortunately, my warranty ended in december 2009. …”

“My vehicle, and doing research there are numerous other Lexus models and years all experiencing oil loss from the timing chain cover gasket causing oil loss that could pose a potential risk to the engine from oil loss and affect drivability and safety. Lexus has not provided a recall on this known issue. They request $3500 to fix the leak with a new gasket. This has the potential to eventually lock up the engine if enough oil leaks out and could cause an accident.”

“I am in fear of my life and any others passengers I may have riding in my car. I think smelling fuel from inside my car and it's very noticeable after I have drove from 1 location to the next. I did have all my recalls completed by local dealership including the fuel delivery pipes. However there is also 3 separate issues for this recall . The recall letter states do not drive your vehicle if you smell fuel and contact your Lexus dealership immediately. …”

“The contact owns a 2006 Lexus IS 350. While the vehicle was parked or driving, there was a strong fuel odor coming from the vehicle.

The vehicle was not repaired and the contact wanted a second opinion. The contact mentioned that the vehicle was serviced per NHTSA campaign number: 09v020000 (engine and engine cooling). The manufacturer was not made aware of the issue. The failure mileage was unknown.”
