2019 Tesla Model 3 air bags problems

“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…”

“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.”

“My 2019 Tesla Model 3 (approx. 95,000 miles) displays a persistent 'Front passenger safety restraint system' alert. The car drives normally and there has been no crash, fire, or injury. Tesla Service's estimate lists $631.60 for the alert diagnosis, $458.50 to replace the front passenger seat Occupant Classification System (OCS), and $699.44 to update the front passenger airbag for compatibility, an update Tesla's own service bulletin SB-23-20-001 requires alongside the OCS repair. The total is about $1,790 before tax. Tesla declined goodwill coverage and said the supplemental restraint system warranty expired in 2023. The alert means the front passenger airbag and seat belt pretensioner may not work correctly in a crash. This appears common: NHTSA's database already holds over 100 complaints on the 2019 Model 3 describing the same alert and repair path. I am asking NHTSA to review whether this is a defect in the occupant classification system. I have the Tesla estimate and will keep it.”

“On September 22, 2026, my 2019 Tesla Model 3 was involved in a very low-speed front collision. The Tesla Vehicle Data Report records the front collision event at approximately 23:21:26.933 and shows vehicle speed of approximately 2–3 mph at the time of the recorded collision. Despite the extremely low recorded vehicle speed, the vehicle’s airbags deployed. The airbag deployment caused an eyebrow/facial laceration that required six stitches and medical treatment. The Tesla vehicle data also shows an accelerator pedal position of approximately 70–75% around the collision event, while brake pressure was essentially zero at the recorded collision timestamp. Significant braking appears in the data after the collision event. I am concerned that the restraint system may have deployed the airbags during an unusually low-speed collision. I am requesting that NHTSA review whether the airbag/restraint system in this vehicle may have a safety defect or an inappropriate deployment threshold. I have retained the Tesla Vehicle Data Report, photographs of the vehicle and injury, and medical documentation. I am also requesting that Tesla preserve the vehicle’s crash data and…”

“On September 12, 2026, at approximately 2:05 PM, while operating on Full Self-Driving (FSD v14.1 Lite) on Hardware 3 (HW3), the vehicle experienced a critical, unprompted loss of path control. While traveling on the highway, the vehicle sharply veered off the left side of the roadway, caught air, and violently impacted an emergency barrier, resulting in the destruction of 9 steel poles and causing physical injuries to both the driver and front passenger. Despite the severe frontal impact and structural collision, neither the front nor knee airbags deployed, raising serious concerns regarding the vehicle's crash-sensing algorithms, structural impact detection, and restraint system integration under this software version. This incident highlights major safety risks associated with running computationally heavy FSD stacks on legacy HW3 architecture: 1. Uncommanded Steering Deviations: The system abruptly executed a violent, unprompted hard turn away from the path of travel, indicating severe lane-detection or path-planning failure. 2. Restraint System / Safety Failure: Critical secondary safety systems (front and knee airbags) failed to deploy in a high-impact…”
