When certain Model 3 and Model Y vehicles receive a different Occupant Classification System (OCS) in their front passenger seats during vehicle servicing, they may require safety vent type front passenger airbags to maintain compatibility between the front passenger seat and the front passenger airbag.

Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering airbags on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
On some Model 3 and Model Y vehicles, the Occupant Classification System (OCS) signal might be affected by electrical interference in the seat electrical harness, causing the airbag indicator to display on the touchscreen.

The failure pattern owners describe
Owners of 2020 Tesla Model Y vehicles report two overlapping safety restraint problems. First, a recurring "Front Passenger Safety Restraint System Fault" warning appears on the dashboard, sometimes triggered by normal passenger weight, sometimes intermittently over months. Tesla's diagnostic codes RCM2_A636 and RCM2_A626 flag this fault. Owners cite repair quotes of $1,100 to $2,000 for sensor replacement or full passenger seat replacement; some have seen the fault recur even after Tesla service attempted sensor bypass. One owner dealt with the issue for over 5 months while Tesla repeatedly claimed the passenger had to sit differently. Warranty coverage ran out around Feb 2023, leaving later-year 2020 owners footing out-of-pocket bills.
Second, and more serious, are documented crashes where airbags did not deploy. Owners report impacts ranging from 30 mph (dumpster) to 70 mph (highway median) with no airbag activation, resulting in fractured sternums, head contusions, broken ribs, torn neck ligaments, and facial trauma from steering wheel contact. One owner hit a guardrail at 55 mph on Autopilot; another experienced a head-on collision at 60–65 mph combined speed. Seatbelts alone provided restraint, often with bruising or injury. Service center response has included long wait times and, in one early case, deletion of diagnostic logs that prevented root-cause identification.
Failure modes owners describe
Safety Restraint System Fault Warning
Dashboard alert indicating failure of passenger safety restraint system. Owners report intermittent warnings that come and go, sometimes clearing on their own, other times recurring months or years apart.
When: Varies: as early as 800 miles, recurring throughout vehicle ownership; one owner reported initial failure within weeks of purchase (June 2020), recurrence at 68k miles; another at 75k miles; another at 90k miles.
Symptoms owners cite: Dashboard warning: 'Front Passenger Safety Restraint System Fault'; Passenger airbag disables when occupied seat weight triggers sensor; Error appears and disappears intermittently; Frequency increases over time in some cases
Codes mentioned: RCM2_A636, RCM2_A626
Repairs/costs cited: Sensor replacement quoted at $2,000; passenger seat replacement quoted $1,500–$1,100 depending on year/variant; some owners report Tesla performed sensor bypass as temporary fix, which failed; retrofitting 'SBR in OCS Equipped Front Passenger Seat' mentioned in one case.
Recalls/TSBs owners mention: Tesla service acknowledges fault. Dealer inspections confirm the error. Warranty coverage appears to end around Feb 2023 for early 2020 models; out-of-warranty repairs quoted above. One owner reports Tesla engineer involvement for damage assessment.
Airbag Non-Deployment in Crashes
Multiple crash scenarios where front passenger and/or driver-side airbags failed to deploy despite impact forces. Includes head-on collisions (60–65 mph combined speed), single-vehicle impacts (30–70 mph), and low-speed parking lot incidents (30–40 mph). Owners report injuries that might have been mitigated had airbags functioned.
When: Failure mileage ranges: 800 miles (low-speed driveway crash), 14,608 miles (40 mph fire hydrant impact), 22,000 miles (30 mph dumpster collision), 30,000 miles (guardrail impact at 55 mph on Autopilot), 45,000 miles (70 mph median crash on Autopilot), 68,000 miles (loss of control in rain at 60 mph).
Symptoms owners cite: No airbag deployment upon impact; Steering wheel contact causing facial/nasal trauma; Seatbelt alone inadequate to prevent driver/passenger forward motion; Vehicle damage concentrated on front and driver-side areas
Codes mentioned: Electrical System (per NHTSA Campaign 23V838000, mentioned in one complaint)
Repairs/costs cited: None documented; vehicles towed or salvaged. One owner reports vehicle severely damaged on front driver-side; another totaled and sent to salvage yard.
Recalls/TSBs owners mention: Manufacturer notified in most cases; one owner reports engineer involvement for damage estimate. One crash (guardrail at 30k miles) had not been reported to service center or manufacturer at time of complaint filing. Recall 23V838000 (Electrical System) was issued after one contact's crash.
Seatbelt Malfunction / Passenger Restraint Module Failure
Driver or passenger seatbelts fail to secure occupants during crashes, or seatbelt system triggers restraint faults. One owner reports seatbelt module error detected early in vehicle ownership; another reports seatbelt failed to lock during low-speed impact, allowing driver to strike steering wheel.
When: Seatbelt module error within weeks of purchase (June 2020, first noticed); seatbelt failure during crash at 22,000 miles.
Symptoms owners cite: Dashboard error: 'Passenger Safety Restraint System Had Failed'; Seatbelt fails to secure driver in collision; Neck, chest, and shoulder injuries sustained due to seatbelt-only restraint during crash
Codes mentioned: Passenger Safety Restraint System Fault
Repairs/costs cited: Owner requested seatbelt module replacement; Tesla mobile tech advised taking vehicle to service center for parts/tools not available at home. Santa Clara service center could not diagnose after mobile visit logs were deleted (delays of >1 month between issue detection and appointment).
Recalls/TSBs owners mention: Tesla mobile technician sent initially but lacked parts and tools; directed owner to service center. Santa Clara service center delayed ~4 weeks for first appointment; service center cited missing notes and deleted logs as reason for inability to diagnose on initial visit.
