The population number noted above is estimated.in the January 15th, 2004 petition request letter to the National Highway Traffic Safety Administration (NHTSA), the petitioner identified 37 voq complaints as related to vehicle speed control issues similar to those the petitioner allegedly experienced in their own vehicle on multiple occasions (as described in the petition request letter).during it's consideration of the request, the Office Of Defects Investigation (ODI) reviewed the 37 complaints and concluded that 34 of the complaints did not involve a throttle control issue as described and alleged by the petitioner; three voqs (one of which is the petitioner's) do allege a throttle control issue.however, the throttle control issues alleged by the petitioner are similar to those alleged in the supporting voqs for preliminary evaluation PE04-021 which involves the throttle control system on model year 2002 and 2003 Toyota Camry and Camry Solara models.based on ODI's review of available service information, it appears the throttle control system manufactured on the Lexus ES300 models is the same as, or similar to, the throttle control system used on the Toyota Camry and Camry Solara models.accordingly, the ES300 models will be added to the scope of PE04-021 and the petition is granted.
