Royal GMC Highly recommended! Justin was amazing!

Reviewed by Juda Stitzer from Lyndhurst, NJFebruary 02, 2023

Our salesman Justin Walker was amazing. He found me my Dream truck while being patient during I my decision making. He made leaving a new truck stress free and we weren't stuck at the dealership for hours! This is our 12th leased vehicle, and by far the best experience yet!! We will definitely be back for our next purchase! THANK YOU JUSTIN WALKER!

3rd issue with the transmission

Reviewed by Amandasteimy from Moscow, PASeptember 15, 2022

A THIRD TRANSMISSION ISSUE Update 9/14/22 here we are again not shifting properly and the engine late came on and we immediately received an onstar alert to service transmission in 7 days so we are again without a vehicle. This entire experience has been truly awful and time consuming. Update as of 8/30- we were told there was nothing wrong with the vehicle on 8/26 and picked it up on 8/29. Today we received a call from GM indicating that the field tech sent out was “still looking into things on the vehicle” in contrast to what we were told by the dealer, and had we known this we would’ve not pIcked up the vehicle. Purchased a certified used vehicle from them at 30,000 miles transmission had a catastrophic failure and left us on the side of the road. dealer would not give us a loaner so we were left without a vehicle for about 20 days. they replaced the transmission and 2 months later we had another issue and began getting error codes for the transmission. We brought the vehicle back and indicated that we'd like to trade it for something comparable since there is clearly major issues with the vehicle. The dealer gave us options that would cost us double our current payment or alternatively more than $100 per month. They also failed to respond to GM until GM asked for a manager. it should be noted that we paid full price for the vehicle when we purchased and did not negotiate and now they are leaving us high and dry with a severely defective vehicle.
