Business ProfileforBart's Car Store

I contacted ****'s regarding a car I was interested in. I met the salesman on 11/13/23 that allowed me to test drive the car (2019 Buick Enclave). The salesman had drove the the car from their *************** store location to their ************* store location as it was closer for me, which I truly appreciated. While I was test driving the car I noticed as I sped up (***** mph) the car would shake (or shudder). I liked the car a lot but did not like the shake. I returned the vehicle and I was asked how I liked it. I said that I did like it a lot but I didn't like the shake when I sped up. I was told by the Salesman that it could be fixed, it was probably just the spark plugs and I said ok. Unfortunately, I did not have it in writing but after signing all paperwork I asked about having it looked at and I then was told that they would make a call to a company they use and schedule an appointment. I agreed. I then went to the appointment on 11/17/23 that was scheduled by the salesman (name upon request). They checked it out & did see there was a problem but said they didn't think it was something they could fix. I then notified the salesman & let him know. He then contacted a ******************** to take a look. I then took it to the transmission company the the same day, 11/17/23 but he drove it for a short time & wasn't sure of the issue so he requested I bring it back. I then took it back on 11/29. They kept it overnight & drove it. I was then given an estimate for $2,000+. I then sent it to the salesman at but was told they would not pay for it stating that the warranty department said my car was fine and the transmission company created a recommendation or suggestion based off of what they think will happen. My issue is that I was told it could be fixed not fixed ONLY if it's broke down. They are now stating it wasn't broken so now they won't fix it. That wasn't our agreement. The agreement was it would be fixed.
