Third time is a charm. Once again lost all oil. Dealer told us a few hundred to replace, this time I had to make an a$@ out of myself but finally part was replaced. Can't understand why it's going out. Car is not running right now. Runs rough and very loud

2nd time we lost all oil, once again it's was the oil pressure sensor/regulator. Dealer argued a little stating the part was not under warranty, they told us only a 12month warrenty. After a ton of arguments they finally replaced.

Lost roughly 2 qrts of oil, the oil light eventually came on. Took this to the dealer and it was replaced under warranty. They said not normal for a Sedona to have this problem.
