NHTSA Complaint #11450041 — 2011 TOYOTA SIENNA

The VSC and tract light stay on all the time. The Ford dealer I purchased the Van from said they had it fixed. I took it back and i was told to buy a new gas cap which I did from a Toyota dealer in my area. The light came on again. I took it back and was told it had an exhaust leak and it won't hurt the van. But I could bring it back for starting at $ 200.00 and have a leak test done on the Van, but it would take hours. Since then I've had cleaner run thru the system but the lights stay on all the time. Is this a safety hazard because its an exhaust leak? Can you please assist in the repair information before I spend hundreds of dollars chasing the problem. Thank You so much.....
