Buick GMC of Mahwah Service Center

"I am someone who has never trusted dealerships for service. I first used Mahwah Buick because I had a warranty on my car that I purchased somewhere else and they were a participating service. I was so impressed with the not only their service but the kindness and professionalism of everyone that works there that I have been going back for all my routine service since. I always feel comfortable, always able to get an appointment and never feel pressured to spend more money for needless repairs. I will continue to have my car serviced there while I own it."

"Staff is fantastic. Delivery couldn’t have been smoother. Car was spotless!"

"Love how I could schedule the service fast and fit my schedule perfectly for the recall-repair to get my steering wheel heating components installed. However, I did deduct one star because I’m actually reviewing two visits. On my visit the week before to get oil change and tires rotated as part of maintenance, when I got home, I found they forgot to add air to one of the four tires, so there was a mismatch by 3 pounds. That was a very strange oversight for a very simple job, good thing we have our own compressor at home so I was able to add Air easily and get the tires to all match. This dealership does remain as my go to place for all my repairs. I say that, without hesitation."

"Service manager Danielle was very courteous and understanding and offered to speak with her manager regarding the cost of repairs. With her help, we came up with a great plan for service for a very reasonable cost. Her smile and confident demeanor is welcoming and reassuring. Thank you!!"

"Let's try to make a long story short - I scheduled the first appointment of the day (Monday, 7:30am) for a *** diagnosis *** of a check engine light. I was the first customer in, yet it took a bit over 3 hours to get the results (an OBDII read and smoke test for the valve cover, over 3 hours!). Also, diagnosis cost $200 after tax and no, they won't deduct it from the work, like most places (they did mention it when I booked the appointment but that's beside the point). I got a quote for the job and had to get the 3rd party warranty involved. After checking multiple times and days with the dealership (same rep so it was nothing new) if they contacted the warranty company, I finally (almost a week later, on Friday) got a response that I need to come in so they can take photos (?!?!) of the issue. A "maybe 15 minutes" thing according to the rep, but they can't squeeze me in on Friday or Saturday and I have, again, to take a half day off and come on a work day. They promised to check if there's another time or anything else they can do, but they never got back to me and I already took my business elsewhere. What a waste of time and money for a diagnosis another shop can't use. I am not coming back to this dealership not for service and definitely not to purchase a new vehicle. I also want my diagnosis fee back since you're obviously don't care about fixing my vehicle! By the way, I didn't want to leave a review, but I kept getting emails and text messages asking me for one, so here you go. New ownership? Yeah, we can tell."
