Love my 2020 Mazda CX5 Grand Touring

Great experience with Hennessy of Southlake. Frank Parker was awesome and represented the dealership well. I flew in from Memphis, was picked up from the airport and everything about the car was as represented online.

Horrible Communication - Not Dependable

Reviewed by JTheDiselTransit350Guy from Cullman, AlabamaAugust 13, 2020

I found a very nice 2017 Transit 350 diesel that was for sale by this group. I made an inquiry and was contacted by a sales person to gauge interest and to start the process. I already had financing ready and was just trying to determine what needed to happen next as i had a trade in and with being 200 miles away, I wasn't sure how a drop off would work. Well we ended up being able to talk through those logistics but it was at the expense of many missed texts and calls on the sales associate part as well as changing from a drop off purchase to a" i must drive in now" purchase. I will also let you know they will not work with you for even 20 minutes on holding a vehicle without a non-refundable 500 deposit . I was on the phone with my lending and was making sure of all the details for the specific car that was being purchased and i was asking if they would just hold it for 10-15 minutes while i was on the phone should someone walk in right that second. I was made well aware that they could do no such thing since there was no deposit on the vehicle, even though if i was in the showroom and working with their banking partners they surely would not have sold the car out from under me in the process of talks. After i was able to verify the car was as listed and the vin matched all the criteria that was stated i instantly made a down payment. and sent over all the information that was asked of me. I know we all get busy at times and even i had to wait a day after making the deposit to get them information on my old vehicle and it had to be the next day as it got too late, myself working in the CST and they are in EST. Fast forward to when i arrived. They had not made known to me all the dents and scratches that were on the car or the tore seats or the marred roof and since it was late when i arrived, we just hurried through the process to get it done. I was a little miffed at the condition of the vehicle but was willing to take it with a grain of salt for the mileage and type of vehicle it was still a good deal. I was told there would be 2 key fobs and the only key they had was a rough cut cut they used to drive the vehicle around the lot. When i texted them a week after driving it home there was no response. I called and left a message for the sales person and a message for the General Manager asking when i might receive the other 2 keys that were promised me. No answer, I called again today and i messaged on Linkedin trying to just understand the time frame. I also texted the sales person again trying to understand the time frame for my 2 key fobs. I feel forced to write this review so that folks will know that what ever service you get out of this group, in my experience, is only until you sign the papers and they have your money. Make sure to get everything you are thinking you will get when you pickup the vehicle and expect there to be a large disparity in pre-purchasing communication and post-purchase communication.

Horrible service department

Reviewed by Matika Jackson from ATLANTAAugust 01, 2020

I had my car towed here on July 3rd because my Enclave wouldn't start. I called and was told they were very busy and would get to my car soon. After a week of not seeing about my car and getting the same response "we're busy" I finally got in touch with a supervisor who told me he would make sure my car was diagnosed. Bill, called and said it was my throttle body on Thursday and my car would be ready to be picked up Friday. Friday afternoon afternoon after nobody called I called just to be told it wasn't the throttle body and he'd have to do another diagnostic and of course he wouldn't be able to look at it until Monday. After several calls and emails I finally was given a loaner. The following Tuesday he calls and says it "maybe" my timing cable and if the valve is broken I may need an engine. Now 2 weeks later they call and say my car is finally fixed and I owe $4400? My car was at the shop for a month, misdiagnosed, and now I owe $4400? I'm just at a loss for words. The service department here is HORRIBLE!!!
