Hello,
I am getting this alert RCM_a021 on my 2019 Model 3 Dual Motor AWD which is out of warranty. The alert disappears when I adjust the seat past a certain height but come back as soon as I lower the seat height. The alert description within the service mode points to the driver side lap pretensioner. I think there is a loose connection somewhere in the wiring harness and wanted to see if anybody her was able to pin point the issue and DIY fix without going to the Tesla Service Center?
I did take the car to the Service Center last week. The service advisor had no clue on what he was doing. He told me the wiring harness needs to be replaced but asked me to approve an estimate of $2375 to replace the entire seat. I rescheduled the appointment without approving the estimate. Upon further google search, I was able to see invoice images from other Tesla owners with the same issue and their total was between $300 to $500. Spoke with the Service Advisor and asked him why he was asking me to approve replacement of the entire seat without first replacing the wiring harness? He sent me a revised estimate for $505 after speaking with his mechanic. The revised estimate still includes a duplicate $180 charge for labor. Sent the advisor another massage to see if that can be removed.
I am frustrated at this point and my fear is that the service center and am hesitant at taking the car to them. It appears that they have no idea on what they are supposed to do. Trying to see if anybody here was able to get this issue fixed on their own?
