Took a vehicle in for service and showed a very clear issue to the service representative. The shifter would make loud popping sounds when going into certain gears. He acknowledged it. Got a call later saying it was normal. Now, I've had vehicles with 400k miles that did not do this and this vehicle did not do it new. It is NOT normal. The first time I took it in they lied and said they fixed it when they hadn't (I had showed the service rep that time the issue as well). I asked if they compared it to another vehicle and they said they didn't so you can only wonder how they would know if it's normal.
