Lexus GS350 Brief Rattle or Knocking Noise on Initial Start Up
A brief rattle or knocking noise may be noted on initial start up. Our technicians tell us if the noise is determined to be coming from the timing chain area, there are updated variable timing gears available to correct this issue.
Rattle every once in awhile when I start the car. It sounded like a loose heat shield to me at first, but it only happens once every 7-8 starts...seems to happen most when I start up the car in the morning, or after it sits for more than 12 hours without a start. I have heard this is a problem with the cam gears and that there is a service bulletin for this issue, but I am wondering if it would be covered for me since the car is out of warranty? - Visitor
My 2007 ES 350 is making the rattle noise at start up. Only when it sits for over 8 hours. If it is the cam gears the labor guides states it is an 18 hour job. Does anyone know if there is a TSB on this problem? - al automotive
