it's very catchy, has an artless simplicity about it rather like Shostakovich but I suspect it was written recently, perhaps especially for the commercial
Most music for commercials is specially composed for each situation. It may sound similar to something familiar, but may not be exactly the same due to copyrights, performer royalties and the like.
The commercial is technically the 2011 Chrysler Town and Country "Touring", Big Finish 2011 promo and the commercial's background song is sung by the "Selected of God" choir, hence the SOG embroidery...
