Generation Buick GMC

If you are considering doing business with Generation GMC, be very careful — especially when it comes to trade-ins and lease payoffs. We traded in a 2022 Chevrolet Silverado on February 21st while lea GMC, be very careful — especially when it comes to trade-ins and lease payoffs. We traded in a 2022 Chevrolet Silverado on February 21st while leasing a 2026 GMC Sierra. We were clearly and repeatedly told by our salesperson that the dealership would handle the lease payoff through Jovia (Fusion), including remaining payments before the March 6th due date. That never happened. For over a month, we were given false information and reassured that everything was taken care of. Meanwhile, Jovia/Fusion had no record of any communication or payment from the dealership. The reality: Two missed payments were reported, damaging my husband’s credit We received a DMV notice that the registration was expiring We have now received a collections letter due to their failure to act The vehicle wasn’t even processed — it was sitting in the back of the lot, not listed for sale Only after physically going to the dealership on April 7th did they admit fault and send the payoff. Even more concerning, when we escalated this to management, they responded once to schedule a call — and then completely stopped responding. This goes far beyond poor customer service. This is a failure to handle financial obligations responsibly, and it had real consequences for us. It is extremely disappointing because the initial buying experience was positive, but the lack of accountability afterward completely changed our view. We will not be returning and strongly caution others to ensure every detail is handled properly before leaving this dealership. More

They send you a video from the mechanic goi from Generation GMC in Sayville compared from King O'Rourke in Smithtown. Service department is amazing. They send you a video from the mechanic going over all the concerns that you have any what they found. I was constantly being told my oul leak was a seel. Thanks to Generation GMC they took the time to find the real cause and it's going to take a week to fix. Thank God had the issues at King O'Rourke otherwise I wouldn't have found an amazing dealership. Especially Thanks to Maria for keeping me updated. More

This dealership had the most shady practices I’ve ever experienced in my life. They took a deposit from me and sold the car to someone else. I even had the car insured and was on the way to the dealer experienced in my life. They took a deposit from me and sold the car to someone else. I even had the car insured and was on the way to the dealership. Absolutely wild the salesman Oz continuing to lie and then John Greene the sales manager was so disrespectful and rude calling me Mr. Customer and eventually hanging up on me. A deal was agreed upon and then they decided to change the deal charging me thousands more and then effectively ripped someone else off harder and sold the car to them. STEER CLEAR. More
