2019 Tesla Model 3. In September 2022, Tesla Service Jacksonville replaced the entire front passenger seat assembly after a front passenger restraint fault alert; invoice 3000S0005274914. In October 2026, the same front passenger restraint fault returned. Tesla's estimate is $1,608.94 for diagnostics, airbag compatibility update, and occupant classification sensor replacement. Goodwill was denied on October 26, 2026, and on November 4, 2026, customer support said the goodwill decision is automated and cannot be overridden. No crash or injury related to this fault. The front passenger seat is not being used until repaired because the restraint/airbag system may not function correctly.

1. Component/System Failed: Supplemental Restraint System (SRS) — Front Passenger Seat Occupant Classification System (OCS) / Occupant Sensor. Component intact and available for inspection upon request. 2. Safety Risk: Failure disables or compromises front passenger airbag deployment and seat belt pretensioner logic. In a crash, the vehicle may fail to deploy the airbag/pretensioner for an adult passenger or deploy improperly, creating severe risk of serious injury or fatality. The passenger seat cannot be safely occupied. 3. Problem Reproduced/Confirmed: Yes. Tesla Service confirmed an active SRS/OCS fault (OCS1P_w127_seatbackSelfOpen). The technician acknowledged this failure is widespread on 2018–2020 Model 3s and noted their own personal Model 3 experienced the exact same issue unaddressed for years. Technicians stated company guidelines require recommending the fix due to liability, though many owners decline due to high out-of-pocket costs. 4. Manufacturer Inspection & Design Defect: Inspected and repaired by Tesla Service. Resolving the faulty OCS sensor required replacing the seat cushion/sensor assembly AND upgrading the front passenger airbag. Tesla redesigned the SRS signaling on newer revisions in a backwards-incompatible manner. This forces out-of-warranty owners to pay for a mandatory airbag replacement simply to achieve physical/electrical compatibility for a failed sensor pad. 5. Warning Messages & Timeline: Persistent "Front Passenger Safety Restraint System Issue" alert on touchscreen and illuminated red SRS/airbag warning lamp on instrument panel. First appeared at ~50,000 miles without physical impact, seat modification, or liquid spill. Remains continuously active. System was ultimately repaired at owner expense.

I’ve been seeing lots of similar front safety restraint issues from other Tesla owners on different sites. This safety restraint issue is regarding the wiring under the seat that get Pinched or Loose Wires: Movement of the front seat can pinch wires or dislodge connectors underneath, triggering errors like RCM_A028 or RCM_a033. If you’re out of warranty, Tesla charges a lot of money to have them fixed but I would say it is a safety issue that they should recall and fix without charge.

There's a faulty connector for the drivers seatbelt pretensioner. The car is reporting RCM_a021_pretenLabFrontLeft and internet searches show this is a somewhat common error for a faulty connector that fails under normal usage.

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.

To Whom It May Concern, I am logging a safety defect complaint regarding my 2019 Tesla Model 3, which displays active fault code RCM_a056 – Front passenger safety restraint system fault. This error deactivates the front passenger airbag and seatbelt pretensioners, creating an immediate, severe safety hazard. The Defect: The failure involves the Occupant Classification System (OCS) seat sensor and affects passengers in two ways: 1. Children (Current Stage): The fault triggers primarily when a child sits in the front seat. The degraded sensor mat cannot process lighter weight accurately, throwing an "implausible voltage" error that disables the airbag system. 2. Adults (Advanced Stage): online data shows this same code eventually locks out for adults due to internal wiring harness fraying or sensor circuit failure. Manufacturer Response: Tesla is aware of this fleet-wide defect and issued Service Bulletin SB-23-20-002 to address it. However, because my vehicle is out of warranty, Tesla refuses to cover this critical safety repair. Service centers are quoting owners $1,300 to $1,500+ out-of-pocket to fix an inherent manufacturing flaw in a federally mandated safety system. I urge the federal safety agency to investigate the 2019 Tesla Model 3 OCS system and compel Tesla to issue a safety recall to fix this hazard at no cost to consumers. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Our seatbelts and airbags required replacement as Tesla stated safety equipment on a Tesla is only guaranteed until 60,000 miles and after that they often need repairs. It was quite expensive. The seatbelts and airbags total cost was $1296.40 and already the Tesla says the front passenger airbag needs to be replaced again.
