NHTSA Complaint #11593668 — 2018 TESLA MODEL 3

The car issued me a "front left safety restraint system fault" saying service is required. The code it flashed was RCM_a021. I am able to get the code to go away by adjusting the seat, however, if i shift my weight or i hit a bump in the road, the warning will appear once again. This leads me to believe that there is a component in the seat that is defective. I took vehicle to the Tesla service center where they found a "broken wire in the pretensioner connector" and they replaced the wiring harness. Upon doing investigation it appears that there are multiple components that are used to determine the firing intensity of the airbags should they go off. If either are damaged the airbags will not fire correctly. Some of these components can be easily damaged due to the seats constant back/forth motion if the easy entry mode is enabled on the car. As the car was outside the warranty period, Tesla refused to cover the costs for repair even though there was a TSB (technical service bulletin) already out on this same issue (reference SB-21-17-005). Total cost for repair including parts, labor and tax was $631.10.
