I chose this dealership to make a change from the one one

Reviewed by Christian Quispe from CTOctober 02, 2025

I chose this dealership to make a change from the one one I was going to get a better service and get quality service but to my surprise my experience was horrible , the service department was supposed to diagnose the car and they did, my car need a new ac blower fan and a new air filter and that is all ! They call me letting me know about the job and price which I agree and then they call me to let me know that the car was ready but to my surprise when I got there the ac wasn’t working properly and decided to speak to the service team again and they see the issue and promise to fix it with not extra charges and they let me have a car for the weekend which was nice because I work and need it transportation. The weekend pass and they call me on Monday to let me know that they found that the car need it a new resistor and the vents were clog with debris and they need it for a least 3-4 hours of work and the new bill that was on top or separate from the first time was almost the same amount ! They apologized for not looking deep the first time and they don’t know what happen but now they want to charge me a fee of $220 per hour and my second bill was going to be almost $700, I told them that is not possible that they charging me with more money for something that should of been done in the first place and is not my fault that their technician are not going above and beyond to take care a customer car ! They ending up not finishing the job and charge me only for the resistor ! The service person at the dealership was very nice but the technician are not and will never trust this dealership to do a job on my car ! This was by far a disappointing experience at a dealership we’re they have the experts and I feel that they don’t care about the quality of their work !

Stuffy… being there reminds me of the dealer experience from my folks buying Buicks in the ‘80’s. Sorry to be honest.
