I have a 2014 terrain which I've only serviced at casa de Cadillac. Alex is the service advisor and Eric is the service gentleman i was working with. On Christmas Eve I started my vehicle in the target parking lot and proceeded to drive, it made a puttering sound and refused to drive in the drive position. I turned the vehicle off and on only to have the same thing happen again. My car ended up dieing. My brother came with his car reader to see what the issue was. He detected a few issues with the camshaft cylinoide. We end up taking it to the service yard where it would be inspected on Tuesday the 26th at 8:30am. I received information on the vehicle around 3 in the afternoon stating that the mass air flow sensor was bad and needed to be replaced. $297 this would cost. I spoke to Eric several times regarding the camshaft cylinoide and my conserns that the problem wasn't being fixed properly. He gave me his word and said my brother was "putting stuff in my head." I again said i was concerned but I trusted his word because, isn't this why we take it to a dealership??? For piece of mind??? They released my car to me around 5pm. Today is December 28th, at my sons preschool my car did the exact same thing!!!! I reversed from my parking spot, and when I went to drive it wouldn't go. same exact thing it did the first time! So my brother comes back with his reader and again same freaking issue!!!!! So we get it to casa de Cadillac and I'm furious!! I have to be at work and they have no loaner car for me. Surprise!! So my awesome brother drove me!! Thank god! So I wait for a call, i missed it by 2 minutes, I called right back thinking they didn't leave a message. Of course he was now with a customer and couldn't take my call. When i got off i received a message from Eric stating the part was under warranty and they were test driving it now. He then says "oh and you also have a slow acid leak on your battery, you might want to have your brother change that." I thought are you freaking kidding me!! You had my car all day on the 26th and not once did anyone mention a battery???? You let me leave the shop in a dangerous situation!!! HORRIBLE!! I drove off with your guarantee I was safe! You didn't even consent with me prior to changing any repairs the second time, not even and explanation!! So when I got to the shop there was a lot of explaining to do on your end! WHAT DID YOU FIX that was now under warranty?? WHY WASN'T I told about the battery on Tuesday? WHY WASN'T I given the option to fix it? Oh wait because you guys know your ripping people off!!! You had taken me for $297 dollars for a $40 part!!! They were definety nervous and I didn't pay a dime. They admitted to there bad by not telling me about the battery, but now the trust is gone. I will not be bringing my car to this dealership and I suggest whom ever reads this take this as a warning! I will be reporting this, , so hopefully they take better care of your car. These greedy corporations take advantage of us because they think we don't know what's going on. It has to stop!!
