I would NEVER purchase a car from here again.
I would NEVER purchase a car from here again. I purchased a 2022 GMC Sierra 1500 AT4 with 40k miles on Friday October 17th. By Saturday October 19th the check engine light turned on after the dealership assured me there was nothing wrong with the car. I took the car somewhere else to get checked out and they told me the code that was causing the check engine light was previously cleared by the dealership. Essentially, GMC of Mahwah knew about the problem and sold me the car anyways. On Thursday October 23rd they asked me to leave work early to bring the car in so it can be finished by Friday October 24th. It is now Monday October 27th and a gentleman from service informed me they haven’t even looked at the car because “the service department is busy with other serious repairs.” I guess my repairs aren’t serious enough? DO NOT BUY A CAR FROM HERE! HORRIBLE SERVICE AND DISHONEST PEOPLE.

The dealership continues to send me emails alleging that they tried contacting me NUMEROUS times at my valid phone number, but were unsuccessful. The emails then go on to say, that NUMEROUS messages were left. NO calls were EVER made to my phone number. NO messages were EVER left. Although the numerous emails state "I", and "We" tried calling and left messages, NOT ONE email EVER identifies WHO was calling, or WHO the "We" was! A reply email was sent addressing these issues, only to receive ANOTHER annoying, unidentified reply alleging the same issues. We, I tried calling, left messages...etc. VERY UNPROFESSIONAL!

This dealership is a scam factory, plain and simple.
This dealership is a scam factory, plain and simple. I came in with a legit pre-approval from Capital One, ready to buy. They ran my credit again without reason, handed me some handwritten “payment options,” and never said a word about switching my financing to Santander. I didn’t find out until the bill hit. That’s not a mistake it’s a setup. And after reading more reviews, it’s clear this is their playbook. Charging nearly $4,000 in surprise fees on used cars, lowballing trade-ins by $5,000, and jacking up the price on a Hummer EV order after two years with no shame. One guy said he left needing a shower, they’re that slimy. Buick GMC of Mahwah doesn’t just hustle they lie. This place runs on deception, and if you don’t walk in with your guard up, you’ll walk out robbed. Don’t say you weren’t warned
