2019 Tesla Model 3 seats problems

Filed Sep 10, 2026 · Airbags, Seats · CA

The Restraint Control Module (RCM) fault code RCM_a056 intermittently appears and disappears on the vehicle's display. This code indicates a fault in the front passenger Occupant Classification System (OCS) — the sensor responsible for detecting passenger presence and weight to determine whether and how the passenger airbag deploys in a crash. Because the OCS sensor is malfunctioning, the passenger airbag may fail to deploy, deploy incorrectly, or deploy with wrong force in a collision, putting any front passenger at serious risk of injury or death. The fault is intermittent — it appears and disappears without any change in vehicle configuration or seating — which is consistent with a failing OCS sensor or degraded wiring harness connection under the passenger seat. No collision or injury has occurred. The vehicle has not yet been inspected by a dealer or service center. No independent inspection has been performed. Tesla has issued Service Bulletin SB-23-20-002, which has been revised at least seven times, acknowledging a known OCS sensor defect across multiple Model 3 vehicles. Despite this, no safety recall has been issued. The repair cost quoted by Tesla service is approximately $800–$2,000 out of pocket for what appears to be a widespread manufacturing defect in a critical safety system. Numerous other Model 3 owners have reported the identical fault code. The component is available for inspection upon request.

Alert RCM_a021pretenLapFrontLeft. Caused by the seat harness wires being pinched and stretched when moving the seat back/forward/up/down. Eventually the wires are damaged by the seat movement. Tesla has touted a feature called "Easy Entry" which moves the seat to a preset position to allow the driver to get in and out of the car more easily. This moves the seat lower and farther back and then moves the seat back up to the driver's position when ready to drive. This increased seat movement, every time the driver gets in and out of the car, causes the wires to wear prematurely and the above fault to trigger. In the event of an accident the driver side airbag may not deploy and/or the seat belt pretensioner may fail to lock the seat belt in place, leaving the driver exposed to serious potential injury risk. This issue can be seen in 2019 Tesla Model 3s and I believe an investigation by the federal safety agency is warranted, at the very least.

I am writing to report a serious safety incident involving my 2019 Tesla Model 3. My goal is not to assign blame, but to make Tesla aware of an incident that I believe warrants review from a safety perspective. While the vehicle was parked, my children were sitting inside watching TV, we were standing 5 ft from the vehicle. My younger son was seated in the front passenger seat, and my older son, not realizing his brother had leaned over the top of the seat, adjusted the passenger seat upward. As the seat moved up, it trapped my younger son's neck against the seat and obstructed his airway. Fortunately, we were a couple of feet away and heard the sound of glass breaking. We were able to free him, and he began breathing again and no serious injury occurs. It was an extremely frightening situation that could have had a much more serious outcome. During the incident, the panoramic glass roof also shattered from the pressure of my youngest son's head. I understand this may have occurred because of the force involved, but I wanted to include it as part of the overall event. I recognize that children should not play inside vehicles unsupervised, but they are 8 and 10 and were not rough housing just watching Netflix in the Telsa. However, this incident made me question whether additional safeguards could help prevent a similar situation in the future. Specifically, I wonder if there are opportunities to improve obstruction detection or pinch protection when a seat encounters resistance near a person's head or neck or making the seat unable to get so close to the ceiling an continue to rise. I wanted to bring this incident to your attention so safety teams can review it. If there is any additional information that would be helpful, including photographs, the vehicle VIN, or other details, I would be happy to provide them.

The Front Passenger Safety Restraint System failed prematurely on my 2019 Tesla Model 3 at only 23,105 miles, triggering the alert 'Alerts - Seats - Front passenger safety restraint system issue/Service is required' and disabling passenger airbag functionality. Upon inspection, Tesla Service quoted $1,285.13 out-of-pocket to repair the system. While the root failure involves a $12 occupant occupancy sensor (Part #1099592-00-F), Tesla's mandatory service procedures require a full subsystem revision cascade to fix it. Specifically, under 'Replace Occupant Classification System (OCS) of Front Passenger Seat while Servicing Subcomponents' and 'Update Front Passenger Airbag to Maintain Compatibility with Front Passenger Seat,' Tesla requires replacing the right-hand seat harness assembly (Part #1489060-03-G) and the complete Front Passenger Airbag (Part #1077823-00-G) solely to maintain hardware compatibility with the revised sensor. Because Tesla redesigned subcomponent hardware without offering a backwards-compatible replacement sensor for earlier Model 3 production units, restoring a critical primary safety system creates an exorbitant financial barrier, forcing the vehicle to be operated with disabled airbags.

I am getting an electrical fault which has disabled my front passenger seat airbags. They need to replace the wiring, which means they also now need to replace the passenger airbag itself because wiring has changed and the old airbag is not compatible with the new wiring. Replace Occupant Classification System (OCS) of Front Passenger Seat while Servicing Subcomponents Update Front Passenger Airbag to Maintain Compatibility with Front Passenger Seat I had this same error 4 months ago and it ended up shorting out the entire electrical system, which disabled autosteer and eventually completely disabled power steering which made the car unusable. Tesla service center called it a water intrusion problem and had to replace the entire front electrical harness system and steering rack costing $4500. Now the problem has resurfaced and I'm afraid I might lose power steering again which is extremely dangerous and could happen any time, in addition to my airbags potentially not deploying.

It was raining and my passenger got in the car (slightly damp). When he sat down, I reveived an error message on the screen saying "Front passenger safety restraint system issue". The airbag light is red indicating that it won't work for my passenger. You should be able to get into a car wet without your airbag no longer working. My understanding is that this is a common problem. Tesla wants > $1000 to replace the seat sensor + requires me to pay to have my airbag replaced so the part matches the sensor. According to Tesla Service Bulletin SB-23-20-002, the new style of seat sensor is strictly incompatible with the older style of airbag (known as a "Full Suppression" airbag). $182 (Diagnostic Fee) $475 (OCS Replacement) $318 (Airbag Update) + Labor + Tax The internet is full of reports of this issue. Just google "Front passenger safety restraint system issue". I do not have an invoice for the repair yet. Tesla's service center's first available appt is in 25 days. This means I have to go 25 days without a passenger in my front seat.

I received a notice onscreen (photo attached) that says "Front passenger safety restraint system issue, Service is required." I did some research online and a number of other owners of 2019 Tesla Model 3 vehicles have received this warning, which involves a malfunction that is a combination of the front passenger seat belt, air bag, and seat sensor for the air bag. A number of people with this year and make have gone to Tesla, and Tesla service workers have said "this a known issue" for this year and make. Since this issue involves a number of safety components, and is a known issue, Tesla should be required to fix this as a product defect recall. Instead, they quoted multiple owners, including myself, approximately $2,000 to fix.

An error message appears every time my husband drives. Whenever he moves the driver seat backwards, “Front left safety restraint system issue” message appears on the display screen.

Warranty Alignment: This failure occurred at 47.7k miles, well under the 60,000-mile threshold of the Supplemental Restraint System Limited Warranty. Known Defect: This repair is the subject of a specific Service Bulletin (RCM_a078), confirming it is a known manufacturing issue and not standard wear-and-tear. Safety Criticality: The SRS is a primary safety system. Forcing a customer to pay for a known defect on a life-saving system at such low mileage is inconsistent with Tesla’s safety mission. I have already paid the high invoice to ensure the vehicle was safe to drive. Tesla did not consider the goodwill repair request for known manufacturing defect that puts passenger at risk. Such safety related repair should be part of safety recalls.
