We had two services performed, first was an oil change and regular service, after leaving the dealer there was a loud flapping under the vehicle when I accelerated on the interstate, I was able to get off on the next exit and work my way back yo the dealership via backroads, the skid plate was loose and they had to replace 3 bolts on it, not sure if they were all left loose or the three were just left out. I scheduled work on the heating system the next day due to no airflow out of the vents on our feet, they found the issue and called with an estimate, we approved the estimate and the work was performed, once complete the total of the repair was 50-75 dollars higher than the estimate. I would expect to at least have a quote on the high end and come in low instead of estimating low, we are lucky to not have a tight budget and been unable to pay more than the estimate.
