Toyota has recalls occuring. This many involve your Sienna. You can verify if it's your 2010 Toyota Sienna that needs something worked on via a recall by running the 17 digit VIN on Toyota's website: https://www.toyota.com/recall?srchid=sem:Support_Recalls:GOOGLE:Recall_Toyota_EXACT::&gclsrc=aw.ds&&gclid=EAIaIQobChMIofSOkZPA5gIVypyzCh08UAFbEAAYASAAEgJPBvD_BwE&gclsrc=aw.ds
I don't think Nalley Toyota handles Sienna. But you can get their contact phone on their website
