Took the car in yesterday for service which should have been oil and filter change and fluid checks. Took over 8 hours to do it. Called numerous times to get an eta and no one would answer or if a message was left no one would call back. I wake up today (next day) and the car tells me to not drive and fill the radiator fluid....so in 8 hours of time at the dealer they did not check this fluid? I call can not get anyone to talk to leave message we will see if they call me back - i doubt it. Will not use them again :(
