I bought my car in for a simple service, coolant flush and oil change. Then a few hours later my car leaked all the coolant out. Firstly when I called I never got a call back from my service advisor. I had to call 3 times until I got him on the phone. Secondly they did not believe my car leaked. I drove my car back, after filling it with water, then had to leave it overnight. I was diagnosed with a broken thermostat. All in all not a great experience.
