Had this issue yesterday and yes it left me stranded. Checked with the closest Acura dealership who quoted $120.00, but not in stock. Got up this morning and stopped at O'Reilly, Napa, and AutoZone, before finally finding a relay at Advanced Auto Parts. In each store's computer system it only shows 1 part of the main relay and not the entire circuit board. The young lady was persistent and finally looked under "relay misc assembly" and found 1 in stock for $68.00. Drove back to my stranded car...hoping it was still there...plugged it in and drove straight home. I was so thankful for the cashier's persistence, that I went back up there with a Monster drink, Kit Kat chocolate, and granola bars to give her. She said that I made her day, but I told her that relay was very important and that she made my day!
