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.

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.

My Tesla repeatedly displayed a “Passenger Safety Restraint” warning related to the front passenger restraint/airbag system. Tesla Service Center in Los Gatos, California attempted multiple repairs over several visits. The first repair identified a pinched and improperly routed passenger seat harness associated with the restraint system. Tesla stated the issue was repaired and tested. The warning later returned. Tesla then replaced the front right seat harness assembly and lap pretensioner. The warning later returned again. Tesla subsequently proposed and/or performed additional repairs involving the passenger airbag, Occupant Classification System (OCS), occupancy sensor components, and additional seat harness components at significant customer expense. Despite multiple repair attempts and approximately $2,100 in repair costs, the same safety restraint warning still exists today. Because this issue involves the Supplemental Restraint System (SRS), airbags, seatbelt pretensioners, and occupant classification systems, I am concerned the passenger restraint system may not function properly during a collision.

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.

SUPPLEMENT TO PREVIOUS COMPLAINT (VIN: ...XXX): CRITICAL NEW EVIDENCE OF MULTI-POINT SAFETY FAILURE. On Dec 10, 2025, Tesla Service performed a full diagnostic and repair of the airbag safety system. In addition to the previously reported "damaged wires" in the passenger seat (OCS Module), the technician ALSO had to replace the Steering Column Control Module (SCCM) to resolve the active safety faults. Safety Implication: The vehicle was sold with simultaneous hardware failures in both the passenger occupant sensing system AND the driver's steering column airbag controls. This confirms widespread physical/electrical trauma to the vehicle's Supplemental Restraint System (SRS) that was concealed at the time of sale. The dealer released a vehicle with compromised safety hardware in both the driver and passenger zones. I have attached the official Tesla Invoice confirming these replacements.

the federal safety agency Complaint Narrative (Copy & Paste) CRITICAL SAFETY DEFECT: SALE OF VEHICLE WITH DISABLED AIRBAGS Incident: 10/24/2025 | Dealer: Braman Cadillac (Miami, FL) | VIN: [XXX] Braman Cadillac sold me this 2024 Tesla Model 3 representing it as "clean/no accidents." In reality, they released a vehicle with a disabled airbag system resulting from a crash that occurred in their inventory. 1. DISABLED RESTRAINT SYSTEM (RCM): Tesla Service Mode diagnostics confirm the Restraint Control Module (RCM) is in "Post Replacement" state, displaying the prompt: "Post Replacement Tasks - Routine requires Service Mode Plus authentication." This proves the airbag computer was replaced following a crash/electrical trauma but NEVER calibrated. Consequently, the SRS is disabled and will not deploy. The vehicle explicitly warns: "The Safety Restraint System may not perform as designed." The dealer released a non-roadworthy vehicle. 2. EVIDENCE OF DEALER KNOWLEDGE: Internal logs show critical crash fault codes (VCFRONT_a059 & RCM2_a003) logged on Oct 15, 2025. Dealer records confirm the car was in their exclusive inventory on this date (listed since Sept 23). These faults were active 9 days before sale. The dealer ignored active safety warnings to facilitate the transaction. 3. CONCEALED DAMAGE: Inspection by Classic Collision confirmed hidden structural damage requiring $9,676.69 in repairs, consistent with the uncalibrated module. CONCLUSION: Braman Cadillac knowingly sold a vehicle with a lethal safety defect. I demand an investigation into their release of vehicles with uncalibrated safety modules.

passenger safety restraint system light came on, Tesla says to fix needs to install OCS filter module and replace existing OCS sensor because its not compatible with existing OCS sensor...cost is $806....there are no broken parts in my car. according to Teslas service bulletin Sep 21, 2020 this problem is caused by electrical interference in the seat harness causing the airbag restrain system message on screen due to faulty design.....Tesla says i need to pay for it because car is out of warranty, i say its a faulty design and they have to fix free. this should be a recall because Tesla is aware of many of same problems that make the airbag inoperable. from the bulletin "On some Model 3 and Model Y vehicles, the Occupant Classification System (OCS) signal might be affected by electrical interference in the seat harness, causing the airbag indicator to display on the touchscreen." Tesla has been aware of the problem for 4 years at least.
