Overall McKinney Buick GMC maintenance has been great! I do have one problem. My Buick only has 3,993 miles on it. However the Buick Cell Phone app shows 39,578 miles on it. For what ever reason; this really bothers me. I would appreciate it if this could be corrected. I've called customer service but they don't think that they can fix it. Any help I can get to resolve this problem would make me feel a lot better. And please don't tell that your systems have been corrected. I need to have the Buick Cell Phone app corrected.
