2019 Tesla Model 3 Airbags Problems

The Front Passenger Safety Restraint System failed prematurely on my 2019 Tesla Model 3 at only 23,105 miles, triggering the alert 'Alerts - Seats - Front passenger safety restraint system issue/Service is required' and disabling passenger airbag functionality. Upon inspection, Tesla Service quoted $1,285.13 out-of-pocket to repair the system. While the root failure involves a $12 occupant occupancy sensor (Part #1099592-00-F), Tesla's mandatory service procedures require a full subsystem revision cascade to fix it. Specifically, under 'Replace Occupant Classification System (OCS) of Front Passenger Seat while Servicing Subcomponents' and 'Update Front Passenger Airbag to Maintain Compatibility with Front Passenger Seat,' Tesla requires replacing the right-hand seat harness assembly (Part #1489060-03-G) and the complete Front Passenger Airbag (Part #1077823-00-G) solely to maintain hardware compatibility with the revised sensor. Because Tesla redesigned subcomponent hardware without offering a backwards-compatible replacement sensor for earlier Model 3 production units, restoring a critical primary safety system creates an exorbitant financial barrier, forcing the vehicle to be operated with disabled airbags.

I am getting an electrical fault which has disabled my front passenger seat airbags. They need to replace the wiring, which means they also now need to replace the passenger airbag itself because wiring has changed and the old airbag is not compatible with the new wiring. Replace Occupant Classification System (OCS) of Front Passenger Seat while Servicing Subcomponents Update Front Passenger Airbag to Maintain Compatibility with Front Passenger Seat I had this same error 4 months ago and it ended up shorting out the entire electrical system, which disabled autosteer and eventually completely disabled power steering which made the car unusable. Tesla service center called it a water intrusion problem and had to replace the entire front electrical harness system and steering rack costing $4500. Now the problem has resurfaced and I'm afraid I might lose power steering again which is extremely dangerous and could happen any time, in addition to my airbags potentially not deploying.

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.

Mar 27, 2026

I am submitting a complaint regarding a “Front Passenger Safety Restraint System Fault” warning that recently appeared on my Tesla vehicle. My vehicle currently has approximately 45,000 miles. This warning indicates a potential issue with the passenger airbag or related restraint system components, which is a critical safety feature. A malfunction in this system raises serious concerns about whether the passenger airbag would deploy properly in the event of a crash. I contacted Tesla service, and I was informed that the repair would cost over $1,500 out of pocket. Given the relatively low mileage and the importance of the safety system involved, I am concerned that this may represent a broader defect rather than normal wear and tear. Additionally, I have found similar reports online from other Tesla owners experiencing the same warning, which suggests this may not be an isolated incident. A failure or malfunction of the passenger restraint system presents a significant safety risk to occupants. I believe this issue warrants further investigation to determine whether there is a systemic defect affecting Tesla vehicles. I am requesting that NHTSA review this issue and consider whether further action, including a potential recall or manufacturer responsibility, is appropriate. Vehicle details (VIN, model, year, etc.) can be provided as needed.

The car was giving me a warning "Front Left Restraint System Fault" (RCM_a021) approximately for 4 months (Jan 2026?) - I brought the car in for service April 2026 and after researching, the technician found that there was a failure in the wiring harness - this is the wiring harness that is responsible for the seatbelt pretension mechanism that activates in a accident. The technician had to replace the harness for the issue to resolve. However, it's my understanding that, had an accident occurred prior to the repair, that the safety system would not have operated properly.

I received a notice onscreen (photo attached) that says "Front passenger safety restraint system issue, Service is required." I did some research online and a number of other owners of 2019 Tesla Model 3 vehicles have received this warning, which involves a malfunction that is a combination of the front passenger seat belt, air bag, and seat sensor for the air bag. A number of people with this year and make have gone to Tesla, and Tesla service workers have said "this a known issue" for this year and make. Since this issue involves a number of safety components, and is a known issue, Tesla should be required to fix this as a product defect recall. Instead, they quoted multiple owners, including myself, approximately $2,000 to fix.

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.

System error code RCM_a021 "Front left safety restraint system issue" The wiring under the front seat may be damaged due to the "easy entry" function which raises, lowers and moves the seat backward and forwards for easier entry and exit of the car. Safety restraint system or airbags may be compromised in the event of a collision if wiring or controls are damaged. Warning code RCM_a021 appeared every time the easy entry function was automatically started.

My Tesla displayed fault code RCM-A056 (Front Passenger Safety Restraint System Fault). This error disables or compromises the front passenger airbag/occupant restraint system. The fault appeared without accident or damage, and Tesla has declined to cover the repair because my Basic Vehicle Limited Warranty has expired. This is a critical safety defect because it prevents the front passenger airbag system from functioning properly in a crash. Tesla has issued recalls and service campaigns related to restraint control module calibration, and many owners have reported the same fault code. I am filing this complaint so NHTSA can investigate whether this is part of a broader safety defect trend and ensure Tesla repairs these failures regardless of warranty status.

Front passenger safety restraint system fault - this seems to be very common issue on Tesla Model 3 where I'm told some wires or sensor is pinched on the seat when the seat is reclined too far back or forward. It could cause an issue with the airbag misfiring or not firing at all during an accident, leading to death. I think this needs to be investigated immediately - this is a common issue and Tesla is not repairing for free. They're quoting people with a "filter" fix which is a band-aid fix only for about 300$ (Tesla says there is 50% change this will fix it) or they want us to replace the whole seat with the sensors that cost close to 1500$. Even with the new seat, the issue has come back few times for many people.

Driving as normal when an alert for a front passenger safety restraint system fault appeared. It went away on its own. I thought it was a software glitch. It would periodically reappear, then go away after a driving session. Last week it persisted between sessions. I learned that if the seat was moved slightly forward or back, then the alert would go away. I scheduled a service with Tesla. Tesla advised that the entire car seat and airbag would have to be replaced for $1800. This is a ~50,000 mile car with no collision history. It's just out of warranty. Tesla refuses to tell me if the car will safety function in an accident or not. The alert is gone, but I have a service estimate that says the car has all of these problems. Major safety concern.

There is an error with my car's Occupant Classification System (OCS) which is giving me an alarm of "Front Passenger Safety Restraint System Fault". Tesla only "fix" is to replace the OCS with what seems to be a newer version. You can tell it is a new version because they are also telling me I need to replace my airbag as my current airbag is not compatible with the new OCS.

The contact owns a 2019 Tesla Model 3. The contact stated that the passenger's side air bag warning light was illuminated. The vehicle was taken to the Tesla Service Center, where it was diagnosed and determined that the passenger's side seat sensor had failed. The seat was replaced with a new seat; however, the air bag warning illuminated after the repair. The vehicle was taken back to the service center, where the contact was informed that the technician had failed to install the module connected to the air bag during the previous repair. The seat replacement was performed a second time; however, the failure persisted, and the contact noticed that the seat was not installed correctly. The contact requested for another service through the Tesla App, but the request was denied. The contact was informed that the vehicle was repaired, and the notification of the failure was due to a glitch in the system. Additionally, while driving at various speeds, there was an abnormal creaking sound coming from the front suspension. The contact stated that the sound became louder while turning. An appointment was scheduled with the Tesla Service Center. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was unknown.

The rear camera on my Tesla intermittently fails when shifting into reverse. Additionally, the rear trunk will not open using the in-car release button, mobile app, or key fob. A warning appears stating the function will return on the next drive, but I am often forced to use the emergency release to access the trunk. I believe this may be related to a prior recall involving the rear trunk harness, but when checking my VIN, no active recalls appear. Tesla service also reports no recalls on file. I am also receiving an intermittent fault message regarding the front passenger safety restraint system, stating that service is required. This is a serious concern, as a malfunctioning restraint system may fail to protect occupants in the event of a crash. Tesla has given me an estimate of $225.00 to address the safety restraint fault and $495.27 to repair the trunk/rear camera issues, with a total cost of $739.60 including taxes. I believe that safety-related repairs, especially those involving airbag and restraint systems, should be covered by the manufacturer and not passed on to the vehicle owner when not due to misuse or damage. The passenger restraint fault poses a direct safety hazard in a crash. The rear camera issue, while less severe, still impacts safety, as the camera provides a wider and clearer view than mirrors alone. I am asking NHTSA to review whether these issues are safety defects and whether they may be connected to known problems or recalls not applied to my vehicle.

Tesla wants >$750 to "fix" a bug it sold in the car, & won't turn off the beep that happens every 5 minutes of driving, telling us that their sensor is defective. They want us to pay to tear the seat apart so they can replace the entire sensor. This error is happening in most of their vehicles (at least 2019 Model 3's). It's probably a Malfunctioning Occupant Weight Sensor (which determines if someone is in the seat and dictates whether the airbag should deploy). This fault triggers the painful loud beep/warning every 5 minutes of driving, & may disable the airbag in a collision. Tesla's systems rely heavily on software, & it may be a glitch or bug, but they say they can't fix it w/o making us pay to take out the seats. Or it may be Wiring and Connection Issues. (We have just 35,000 miles on this vehicle.)

We have recently incurred an alert that comes on as it pleases and has no rhyme or reason for popping up with passenger airbag restraint issue. Tesla is wanting to charge us over $900 to fix this issue yet this isn’t an us issue it’s a them issue. They installed a faulty airbag sensor which now requires the replacement of sensor, airbag, and harness as well as a software update. I have seen thousands of complaints online in regards to the same error code. This is something Tesla needs to take ownership for. This isn’t a wear and tear item, these airbags have never been deployed, so why are we being punished! Recall these cars they are a hazard

Tesla has just informed me about a safety concern on the 2019 M3 They explained that despite of the car not giving me a notification, it is showing on their end that my car has an airbag safety concern and by law they have to tell me. So I asked why this recall is not being addressed and fixed by Tesla. They told me that is my choice and if I choose to be safe I have to pay. This is not acceptable. Recalls that fail the nhtsa standards need to be accounted and addressed by the manufacturer. Please assist I find interesting that I didn’t receive a notification but they have and we all know that notifications can be manipulated by Tesla.

Started getting intermittent RCM_a056 faults stating "front passenger safety restraint system fault". Apparently this can be a safety issue as the airbag may not deploy and seems to be a common issue reported by owners. Tesla is charging owners to fix this safety issue, which in some cases is completely replacing the full seat and airbags. Instead, this should be covered under recall or bulletin fix.

May 16, 2025

Around February or March of 2025, my Tesla Model 3 (year 2019) began to flag an electronic warning for a passenger occupancy sear sensor and recommended immediate service. The sensor and warning did not stay on and would only appear intermittently. I still decided to service the vehicle and took the car to the manufacturer service center closest to me in May 2025. I was quoted for $500-$600 to repair the sensors. Later the quote was updated to over $1,200 because the new sensor was “not compatible” with the old air bag. It seems like Tesla intentionally or knowing used an updated sensor either because the old sensor was known to have issues or because of refreshed models but then did not ensure they used a part that worked with their existing model cars. This seems like a major safety issue and requires customers to pay twice their expected repair cost in order to ensure basic required safety functions work on a 6 year old car. I clarified with the service advisor that if I did not replace the airbag that they would not deploy in a collision and they affirmed my understanding which forces me to have to replace the airbags on a 6 year old vehicle for no reason other than Tesla’s poor safety planning.

The front passenger seat’s OCS required a service bulletin application, involving a retrofit of the seat belt reminder sensor and component replacement, confirmed by a Tesla technician. The repair likely falls under TSB SB-19-20-003 (2017-2019 Model 3), addressing OCS electrical interference causing airbag indicator issues, which can affect seat belt reminder functionality. The TSB involves retrofitting parts My 2019 Model 3 (39,140 miles) needs an OCS repair per SB-19-20-003, a known safety issue from 2019 affecting airbags and seat belts (FMVSS 208). Since it’s a manufacturing defect and a safety risk this should be under a recall.
