general problems of the 2019 Tesla Model 3 - part 1

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 left safety restraint. Airbags won’t deploy due to this issue.

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.

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.

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.

Passenger restraint system fault causing the system not to sense the presence of front passengers. This could possibly lead to safety systems for the passenger to not work in the event of a crash.

The contact owns a 2019 Tesla Model 3. The contact stated that a creaking noise was emitted from the area where the front suspension would be. The noise would be louder when turning the vehicle either left or right. The passenger air bag light was illuminated. The vehicle was taken to the dealer, who diagnosed that the seat sensor had failed. The seat was replaced with a new modular seat. After the repair was completed, the air bag warning illuminated. The vehicle was returned to the dealer, who performed the same repairs. The warning light persisted. The dealer was contacted and then informed of the creaking noise and the air bag warning light remaining illuminated. An appointment was made with the dealer. The vehicle was not diagnosed or repaired. The manufacturer was informed of the failure. The failure mileage was unknown.

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.

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.

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.

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.

A warning alert message popped up stating “rcm_a056 front passenger safety restraint system fault”. I contacted Tesla dealer and they said at is out of warranty after 5 years and my car is 6 years old. On searching internet I noticed several people have same issue. Tesla said there is no recall at this time. Since this is a safety critical system which affects the air bag deployment, can NHTSA investigate and see if this can become a mandatory recall. Tesla are quoting $1130 for repair!.

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.

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.

The airbag and seat belt system on the driver's side is faulty, which may result in an unsuccessful deployment of the airbag should I get into an accident. This is an immediate safety concern, yet Tesla would like to charge me over $400 to remedy the situation. That's why I'm reporting this as a safety recall so that no other owner/ leasee faces this risk or financial burden.

I along with many people online have reported the occupant safety restraint system having an issue and setting off a fault. I took it back several times on a warranty to Tesla. However, they were unable to replicate the air. Now the air is started again. The car is out of warranty and tessa wants $2000 now to put in a new airbag new occupant sensor and clip. This is absolute ridiculous, and has really undermined my faith in Tesla. They should not be having occupant faults. And not fixing it.

I am submitting a complaint regarding an unresolved safety issue with the front passenger restraint system in my 2019 Tesla Model 3 (VIN: [xxx] ). Since February 2024, I have encountered recurring alerts for this system, despite multiple service visits to address it. Service history and concerns: the initial repair attempt on February 27, 2024, involved Tesla replacing the occupant classification system (OCS) filter module. However, the alert returned shortly after, showing the issue was not resolved. On October 14, 2024, I returned to Tesla, where they quoted $1,800 for further repairs, claiming my general warranty was expired. Their records indicate that this failure directly impacts the front passenger’s safety restraint, making it a serious defect. During a follow-up visit on October 23, 2024, the issue was confirmed but left unaddressed unless I paid out-of-pocket. This recurring fault poses a critical safety risk, as a defective restraint system compromises passenger protection in a crash. Tesla’s refusal to provide coverage, despite prior similar recalls for restraint systems, suggests a pattern of shifting safety costs onto consumers. I request the NHTSA to investigate this fault’s prevalence and require Tesla to provide a remedy that upholds passenger safety. Thank you for your attention to this serious issue.

The OCS filter (occupant classification sensor) failed causing a “passenger restraint system fault”. This is simply a poorly designed component that fails. It is extremely common. The repair was quoted at nearly $2000 because the airbag and module have to be upgraded alongside it. Tesla sold a bunch of cars with a faulty $15 sensor, and is forcing $2000 worth of repairs just to get the passenger safety system to work.

Front left safety restraint system fault alert which requires service from Tesla service center. Tesla is charging $360 before taxes to fix this issue which seems to be an ongoing issue for many Tesla owners. The cost should be on the company since it’s a safety concern.

Front left safety restraint system fault/service is required.

There is a common warning message on Tesla Model 3 and y that states “front passenger safety restraint system fault” I just received it on mine. Tesla service advised that the passenger airbag and safety system may not function in the event of a crash. I searched online and can see in forums that many people receive this warning. Tesla also confirmed that if someone receives this message while driving and then they get into an accident during that same drive, the airbag may not work. This is a huge safety issue, and Tesla should be held accountable.

Over the last few days, an alert has come and gone numerous times indicating a fault of the front left safety restraint system. As of today, the alert persists and does not go away. The computer reports an error code of “rcm_a021 front left safety restraint system fault. Service is required. ” additionally the airbag indicator is illuminated, which I believe means that it is disabled because of this error.

There have been a number of Tesla’s coming back to the dealership due to a left or right pseat restraint error, which is the seat restraint module failure or even pinched wires that have not been secured properly during manufacturing. This is a safety issue that Tesla needs to correct as they are charging customers between $460 and $1500 to be repaired and these faults end up coming back time after time. Any other car manufacturer would replace on a recall.

Seat sensor error. "front left safety restraint system fault" car was still under warranty when the right seat fault happened. Clearly an issue with Tesla since there are many reports out "restraint system fault".

While driving I received an error on the screen stating “front passenger safety restraint fail -service needed”. This would go on and off randomly. It took over a month to get into Tesla. By the time I got into service the error was gone but Tesla replaced a sensor and airbag to be complaint with the sensor costing over $1300. I have seen a lot of posts of other Tesla owners experiencing the same error.

Safety issue: got a "front passenger safety restraint system fault" (code rcm_a056) out of a sudden. Apparently, the passenger's occupied-seat sensor is not communicating with the system, leading to potential hazard in airbag deployment scenario. Upon reaching out to the Tesla service center, got a quote for $1600, which includes a replacement not only of the passenger's seat sensor, but there's also a need to replace the airbag - to maintain compatibility with the new sensor. Upon additional research, I've discovered that this is not merely wear and tear; some owners reported that this error appears on brand new cars. In short, Tesla is requiring customers to pay $1600 to cover a design failure that could result in a safety / injury. The company should be held liable to its errors, not customers.

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. ).

An error has displayed on the screen stating: "front passenger safety restraint system fault rcm_a056 service is required" and reaching out to the local Tesla service center, I discovered the prescribed repair costs $1600. After searching online for other owner's experience with the error, I discovered that this is a common issue caused by a wire connection to the seat control model coming loose due to a poorly tensioned connector. Those other owners have reported that Tesla knows about this issue in their manufacturing and is refusing to fix the issue or issue a recall even though it is a safety issue.

Front passanger safety restraint system fault.

Car repeatedly shows a warning for "front passenger safety restraint system fault. " the error goes away after a few minutes usually, but comes up frequently - about 1/2 of all drives.

Called Tesla about it in may 2024 and they said it's a safety hazard and we need to replace the entire front seat and seatbelt, estimated at $1,500 and multi-day repair. Warranty expired last year which may explain difference in recommended repair. Friends with same car have been experiencing the same warning and there are many reports of it online.

Driver-side airbags deployed for no reason. While my husband was driving, the Tesla screen showed that the crash had been detected, so airbags were deployed, and he was asked to call 911. However, no collision occurred. Attaching photos of the towed car. Police came and didn’t make a report since no collision was present. After the tow truck towed the car, and a couple of hours later, we went to pick up our belongings; we couldn’t access the trunk, the car was fully dead. However, the charge was 71% before the deployment of the airbag.

Occupant sensor and wiring harness in the front seat becomes "pinched" under the seat when my son sits in the seat. Error code comes up on the dashboard.
