I will not use Bob Ross Service Dept. in Centerville, Ohio for maintenance on my GMC Acadia ever again. They perform services that are unneeded, and I have figured out that this is not a one-time occurrence, but rather a trend over the past 4 years. A $50 oil change and tire rotation turned into a $600+ nightmare. Not just once, but on two separate occasions. To test and replace a battery: over $200. I have been taking my cars to dealership service departments for 30 years, and never developed this much distrust until servicing my GMC at Bob Ross. I thought the first incident when this dealership recommended unnecessary service was just an unfortunate occurrence with my vehicle, but when it happened the following year, I realized that they purposefully recommend services not suggested by the owner's manual and not really needed at all. When I questioned the service manager about this, he admitted that the service advisors are paid commission based upon how much service work they can talk you into performing on your car (apparently, whether it's needed, or not). This type of commission system is unfair to customers and should not continue. I hate to think about how many customers they may have taken advantage of beside me. They won't be receiving any of my money again. If I could rate Bob Ross less than 1 star, I definitely would.
