I am still under warranty, but the service guys keeps saying, that if they drain the black fluid from the rear, and put in new, and the whine stops, it's just a service and I have to pay for the oil.

The check engine light has come on numerous times, and all I have done was open the Gas tank lid and it would go off.

The service guy said, it would go off after three days, and I told him it goes off after three start ups. I hate paying to put it on the machine and find nothing wrong. The cost to find out what "might" be wrong is $125.00. But if they find something wrong, then no charge. I am having a hard time believing anything right now!
