I have been leasing a car from them for the last year, still have two years left to go. Before the first year was even up I began having problems with my Mazda 3. When I called in to the service department and explained that I did not feel safe (my car is shifting out of gear on its on and stalling out) they told me they didn't have any loner cars available. I asked to speak to a manager and then suddenly she was able to "come up with one". The service guy basically told me that I was crazy and treated me like a dumb blonde that didn't know what she was talking about it. He said he could get it to duplicate the issue I was experiencing and sent me on my way. Well, cut to about two months later and last night I had the same issue again, only worse this time and now the check engine light came on. I called this morning and explained what was happening and that I do not feel safe driving the car all weekend. AGAIN they tell me that they do not have any loner cars available!!! I asked to speak to a manager, and was told someone would need to call me back. Receiving a loner car is part of my lease agreement. They don't seem to grasp the concept of "unsafe". I will NEVER go through this dealership again, let alone get another Mazda vehicle. I would never recommend anyone to this dealership. Not to mention the fact that my sales rep was a total moron also. I should have seen the red flags from the get go.
