Business ProfileforJeff Haas Mazda

I purchased a 2014 Mazda 6 from this dealership, and although it was used and basically "as is," I purchased the extended warranty just for that reason, my first issue was ,i kept hearing this beeping noise while driving I even recorded the noise, i brought it in several times,and they could not tell me what was causing it and if it would be an potential problem, ended up taking the chip out for the GPS , so now I have no GPS in the car gotta use my phone.Fast forward to the battery I keep getting this " Iloop inspection required " on the display screen, I've brought it in multiple times, ended up having to pay $400.00 for a new battery, and I'm still getting the same message, I'm noticing a pattern I drive it about 2-3 months, and the same message pops up on the screen.I'm getting excuse after excuse from them not knowing what's causing this issue, not to mention how inconvenient it is having to keep taking it back and forth for service, ( while being charged an diagnostics fee ).now their telling me it's the capacitor, which is not covered by my warranty ( what a coincidence ) and it's going to cost $ 1600.00 to replace, but at first they told me it wasn't the capacitor.. feel like I'm being scammed I'm done with Mazda's.. this has been a bad experience by far.these are supposed to be professional mechanics, but I can't tell.
