Today I received the second letter from the dealer; they made me an appointment for 35K Maintenance Service. I already had changed the air filter, oil filter and the lube oil, but they don’t know this, because I didn’t change to the dealer.
My question is: It is really necessary to make this Service Call? I will lose my warranty somehow if I don’t do this.

And also, if someone can help me with a VIN check I will be very thankfully
VIN: 2A4GM68456R826302

My e-mail address is: sorin1307@yahoo.com

Thank you
