I was in today for service on my leased 2017 Nissan Rogue SL AWD. At the time of lease, no details were provided on a maintenance program so when the first oil change was complimentary, this was a welcome surprise. At that scheduled service appointment, I was informed that the first 2 oil changes were included. When it came time to settle up today, I was informed that my 2nd oil change was no longer included in my lease. I later asked to speak to someone regarding the detail and why they had changed. I made certain to speak softly as to not draw attention to the situation as I was only looking for an explanation, not a handout. This must have been perceived as an affront to Charlie as he immediately took a defensive, confrontational and adversarial position with his tone, affect, and attitude. I was informed, tersely, that Walser sent out a notice stating that they would not honor complimentary oil changes past January 2018 and was additionally instructed that just because Walser purchased Wayzata Nissan, they were not obligated to honor previous commitments. After questioning why I didn't receive the notification regarding the change in maintenance, I was belittled and spoken to in a derogatory fashion with phrases like 'I can't explain this any simpler' or 'I can't make you understand' and 'I don't care' in regards to my exception to how the issue was handled, or more correctly mishandled. One might expect this type of action from a junior employee but this came directly from Charlie - who I assume is a manager as he came out of the front corner office. I will make every effort to buy out my lease, never do business with Nissan, and especially avoid Walser at any cost.
