Dash board appeared safety issue warning and ask to contact dealer. I have been to dealer 3 times since bought the vehicle last year. The first time it appeared was after I bought the vehicle for a week. I brought the vehicle back to the dealer and ask for a refund or exchange another one, and was denied. I happened 2 more times and I brought in again. They said that they adjusted the sensors for a less sensitive level. I contacted toyota to exchange or return the vehicle last year. They got my information down and never replied to me until now.
