Serpentine drive belt along with its hydraulic tensioner gives clattering noise on cold start and low speed acceleration. There has been a tsb EG01501 about this issue. Toyota certified mechanic told me it is very dangerous driving with this noise. The belt tensioner may break, which can cause severe crash.
