2018 Tesla Model 3 Air Bags & Restraints Problems

Safety Restraint Warning appeared on a 50k miles Tesla Model 3. We are a used electric vehicle dealer in California. This warning has been appearing on parked vehicles repeatedly. Meaning, many of the Model 3's we have listed for sale (over 30 units for sale at any given time) will suddenly have a "Safety Restraint Warning" appear. Tesla is not taking responsibility for this. They always charge the customer. The airbag system is inoperable with this warning. It's a problem on EVERY Model 3 on the road between the year of 2017 to 2020.

Tesla refuses to fix recall NHTSA No: 22V798.

I received a safety alert on my car screen: Front passenger safety restraint system issue. Service is required. The front passenger safety restraint system fault typically involves a malfunctioning occupant weight sensor in the passenger seat, which controls whether the airbag activates or deactivates EVGOER. This is a serious safety concern because the airbag may be disabled at that seat location in the event of a crash. The issue is often caused by loose, broken, or unplugged harnesses or connectors under the seat, particularly related to the Occupant Classification System (OCS) Tesla Owners OnlineDigital EV Doctor. Many owners report this happens because wires under the seat get crimped over time due to Tesla's "easy entry" feature that automatically moves seats. Since this a widespread Tesla Model 3 problem, I believe this should be a recall.

The contact owns a 2018 Tesla Model 3. The contact stated that while driving at approximately 30 MPH through an intersection, another vehicle t-boned the driver's side from the driver's side front bumper to the rear passenger door. The contact stated that the air bags did not deploy as intended. Medical attention was needed after the contact sustained lower back, left shoulder, neck, tailbone, and internal bleeding injuries were sustained. A police report was filed. The vehicle was taken to a collision center, where it was currently pending an inspection. The manufacturer was not notified of the failure. The failure mileage was approximately 88,894.

The "Front passenger safety restraint system" is prone to errors because the wiring for it beneath the seat is prone to getting knocked loose and electrical interference

I have an active alert on the drive side safety restraint system. Alert code RCM_a021. I have noticed this appears to be a common problem. A recall should be issues as this a a safety issues and lives could be at stake.

The car's dashboard display shows an alert "Front Passenger Safety Restraint System Issue". This puts the front passenger at risk.

Passenger restraint fault message randomly comes on.

My 2018 Tesla Model 3 began showing a "front passenger safety restraint fault" alert within the last week or so. I scheduled service and then received an estimate of almost $1000. When I corresponded with Tesla through their app, they told me the diagnostic code is: RCM_a056_passengerFrontOCS, indicating failure of the passenger Occupant Classification System (OCS). The OCS controls whether and how the airbag deploys; failure could prevent deployment or cause improper deployment in a crash, creating a serious safety risk. Tesla acknowledges the fault but told me the repair (replacing the OCS and passenger airbag) will not be covered since the car is out of warranty. Tesla has issued service bulletins (SB-19-20-003 R1, SB-23-20-002 R7) for known OCS issues, and many Model 3 owners have reported the same fault. This appears to be a widespread safety defect and should be investigated as a potential recall.

Driving a 2018 Tesla Model 3, driver seat shows message "Front left safety restraint system issue. Service is required". This occurs when the driver is in the seat with the seat belt fastened and the vehicle is in motion. This issue refers to the possible seat belt, seats and/or air bags failure. This is a threat for drivers as these are the front line of defence in case of any collisions or accidents. This issue has been reported by multiple Tesla car drivers and their posts are available on online forums. Message appears on the Tesla screen driven. Tesla does not cover this out of warranty. My appeal to NHSTA is this is hazardous to drivers and cars should be recalled and repairs should be covered.

Getting a notification for "Front left safety restraint system fault" which disengages the airbags. Seems like a very common fault with Teslas but no recall has been made.

A sensor for the driver side safety restraint system was displayed from the vehicles screen. Potentially loose wires under the seat when manufactured.

Vehicle is displaying an error message "Front passenger safety restraint system fault" and "front passenger safety restraint system fault. Service is required." This has the result of "The restraint system may not function as designed." According to an Internet search, this is a very common fault, caused by "interference" and necessitates an occupancy sensor, wiring harness and airbag module exchange.

When seat is moved up for my [XXX] daughter, who is learning to drive, it now triggers an error an indicates the air bags will not work. The error code is RCM_a021. It seems the vehicle has a defect that over time the connections for the front seat harnesses will fail. This is a known issue with a Service Bulletin - SB-21-17-005 on your website from December 8, 2021. [XXX] Manufacturer has confirmed the issue, but refuses to replace it unless they are paid more than $800 (although, online people report that when they were under warranty the cost for parts and labor was in the $300 range).

An error code (RCM_a056) will intermittently come up and say there is a fault with the front passenger safety restraint system. It will turn on for a car ride and stay off for a few days and come back randomly. When I researched this code, I found that this is a known issue with 2018 Tesla Model 3's. Apparently there was a flaw in the airbag system which causes this safety concern. I contacted a Tesla service center and they said it would cost $300 just to check it out and another one said +$1000 to "fix". I called their customer service line explained that this should be covered for free since it is not due to "normal wear" but rather should be a safety recall. I also explained this to the service techs but they just said they can't do anything. If I would have been involved in an accident, my wife could have died because of this safety flaw. The vehicle is still under warranty until 120,000 miles. Thank you for your consideration on this matter.

I believe this is a safety issue that warrants a recall notice since the seat restraint system may not work correctly due to an electrical connection issue. I get an error message "Front left safety restraint system fault" that comes comes and goes depending on the position of the driver seat - if I raise the seat I get the fault message, if I lower the seat the message goes away. This is clearly due to a loose electrical connection in the seat restraint system. I removed the cover at the side of the seat and have identified a loose yellow/orange plastic connector to the left of the seat (see picture). When you jiggle that connector the error message goes on and off. Tesla will fix the issue for $650, but I believe this is a faulty design issue that causes the connector to get worn every time you adjust the seat, and it should be fixed by Tesla at no charge.

Got an alert on the Tesla screen on 4/21/2025 indicating "Front left safety restraint system fault". Took to Tesla Svc Center and they replaced seat belt lap pretensioner, seat belt reminder vent, seat belt reminder sensor box and first row occupancy sensor. Cost $650. Alert goes away if I raise the seat and comes back if I lower the seat. I asked Tesla while scheduling an appointment whether it was a safety issue and they said "Yes". Vehicle has only 43,500 miles on it.
