Agree.
My 2013's driver seat started rocking only when doing quick stops. Now it has progressed to rocking even during low speeds slowdowns.... I had an appointment, the issue was verified, and a new seat was recommended but needed to be reviewed by engineering. I was told engineering would look into the issue within 2-3 days and I would hear back. It has been over a week and I didn't hear anything. I scheduled a new service appointment and got a text that engineering still hasn't looked into it and they wanted to cancel my Sept 14th (next available) appointment that I created. I asked them to not cancel such and I expect the issue to be resolved by then as it is considerably worsening and seems to be a safety risk. So far it has not been canceled. It seems like this a common issue and if they can't fix it/blow me off by canceling the appointment -- I'll be filling an NHTSA report. My seat feels like it is moving almost a half-inch (if not more).
would you ask them if the service bulletins apply to your problem and if they tried the repair described? Curious why they are reluctant... maybe parts or tool isn’t available? Or they learned it doesn’t work? Or they don’t even know?
