My 2000 Seville STS is in the shop for the same problem plus some other work. The service advisor called and said that it was a steering sensor that they replaced under warranty and I should have my vehicle back tommorow.depizzof said:Thanks for the info. I will bring it to the dealer next week when the extended warranty becomes valid. I have not had the message in three days but know if it has come up as it has recently, then something is starting to go bad. I hope to come out with only having to pay the deductable.
