During a maintenance visit to east coast Toyota of carlstadt, NJ an "update" to the ecu computer system was performed. After this "update" I noticed the engine stalling, then recovering and auto then surging forward. This was explained by Toyota as "Smart technology" to modify eng/ect system. In my opinion this is a dangerous "fix": example --when trying to enter a traffic lane from a dead stop, with foot on break if you attempt to accelerate the engine cuts out- sending you into traffic with a lag instead of a power boost. I attempted to have this modification undone by Toyota but they explained their position as below: we apologize for your concerns with the Smart stop technology installed in your 2008 Toyota 4runner. As we previously indicated, in response to customer¿s concerns with their vehicles, Toyota worked with the national highway traffic safety administration (NHTSA) to come up with this remedy, which is the installation of the Smart stop technology. Because this remedy was mandated by the government (NHTSA), we are unable to remove the Smart stop technology. Your email has been documented at our national headquarters. In my opinion this change doesn't fix anything - it is dangerous- you can't accelerate from a "holding" break position (foot on break and gas) as recommended by some defensive driving instructors. . I am requesting that the ntsb looked into this Toyota modification (before update code 33562000,after update 3356200) , determine it's efficacy (or lack of ) and devise a better fix than their so called "Smart technology".
