Seats Problems of Tesla Model 3 - part 1

Safety restraint system TSB technical service bulletin, a known problem with my 2019 Tesla model three.

See all problems of the 2019 Tesla Model 3 🔎.

My Tesla Model 3 has a persistent rcm_a056 alert indicating a problem with the front passenger occupancy detection system. The unresolved fault affects the operation of the front passenger airbag system. I paid Tesla approximately $1,000 for a repair intended to resolve this problem. Tesla replaced multiple components associated with the passenger seat/occupancy detection system, including the sensor, wiring, and other safety-system components. The repair did not resolve the problem. The rcm_a056 alert remained unchanged after the repair. I returned the vehicle to Tesla for further diagnosis. Tesla tested the individual components and documented that they found “no issues present,” but the rcm_a056 alert remained. Tesla then recommended replacing the entire passenger seat assembly at a cost of approximately $3,000. When I asked what diagnostic evidence indicated that the seat assembly was defective, I was told that they had no specific evidence that replacing the seat would resolve the problem. They were unable to identify a failed component and indicated that replacing the entire seat was the only remaining repair they could suggest. I am concerned that this represents an unresolved safety-system defect. I have already paid approximately $1,000 for a repair that did not resolve the fault, and Tesla is now recommending another $3,000 repair without identifying the cause of the failure. The vehicle remains unavailable for normal use because of the unresolved passenger restraint/airbag-system fault. I am requesting that NHTSA document and investigate this potential safety defect, particularly if other Tesla Model 3 vehicles are experiencing the same persistent occupancy-detection failure.

Alert rcm_a021pretenlapfrontleft. Caused by the seat harness wires being pinched and stretched when moving the seat back/forward/up/down. Eventually the wires are damaged by the seat movement. Tesla has touted a feature called "easy entry" which moves the seat to a preset position to allow the driver to get in and out of the car more easily. This moves the seat lower and farther back and then moves the seat back up to the driver's position when ready to drive. This increased seat movement, every time the driver gets in and out of the car, causes the wires to wear prematurely and the above fault to trigger. In the event of an accident the driver side airbag may not deploy and/or the seat belt pretensioner may fail to lock the seat belt in place, leaving the driver exposed to serious potential injury risk. This issue can be seen in 2019 Tesla Model 3s and I believe an investigation by the NHTSA is warranted, at the very least.

I am writing to report a serious safety incident involving my 2019 Tesla Model 3. My goal is not to assign blame, but to make Tesla aware of an incident that I believe warrants review from a safety perspective. While the vehicle was parked, my children were sitting inside watching tv, we were standing 5 ft from the vehicle. My younger son was seated in the front passenger seat, and my older son, not realizing his brother had leaned over the top of the seat, adjusted the passenger seat upward. As the seat moved up, it trapped my younger son's neck against the seat and obstructed his airway. Fortunately, we were a couple of feet away and heard the sound of glass breaking. We were able to free him, and he began breathing again and no serious injury occurs. It was an extremely frightening situation that could have had a much more serious outcome. During the incident, the panoramic glass roof also shattered from the pressure of my youngest son's head. I understand this may have occurred because of the force involved, but I wanted to include it as part of the overall event. I recognize that children should not play inside vehicles unsupervised, but they are 8 and 10 and were not rough housing just watching netflix in the telsa. However, this incident made me question whether additional safeguards could help prevent a similar situation in the future. Specifically, I wonder if there are opportunities to improve obstruction detection or pinch protection when a seat encounters resistance near a person's head or neck or making the seat unable to get so close to the ceiling an continue to rise. I wanted to bring this incident to your attention so safety teams can review it. If there is any additional information that would be helpful, including photographs, the vehicle VIN, or other details, I would be happy to provide them.

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.

Component/system: the front passenger occupant classification system (OCS) in my 2018 Tesla Model 3. The vehicle is available for inspection on request. Description of the failure: the vehicle intermittently displays "front passenger safety restraint system fault — service required]" on the center touchscreen. The alert first appeared on or about 4 years ago and has recurred approximately ~50 times since. The failure is strongly correlated with cabin temperature. It appears after the vehicle has been parked in direct sun in warm weather, and clears on its own once the cabin cools. It has not occurred in cooler ambient conditions. Safety risk: on this vehicle the front passenger seat uses a capacitive occupant classification system rather than a simple occupant-detection pad. The restraint control module uses OCS output to determine both whether the passenger airbag deploys and at what force. When the system faults, I have no way to know whether the passenger airbag is suppressed, will deploy at an inappropriate force for the occupant, or will deploy at all. This directly compromises frontal crash protection for anyone in that seat. I have been avoiding seating passengers there as a result. Inspection and confirmation: the vehicle is outside the basic warranty. Per Tesla's own service documentation, the passenger-side OCS sensor is not individually serviceable; the remedy requires replacing the seat cushion assembly and running a proprietary calibration routine that requires a cabin temperature near 68°f. The vehicle has not been inspected by police, insurance, or any independent shop. Prior warning symptoms: the touchscreen alert described above is the only symptom. There was no prior indication. There is no open recall for this condition on my VIN. Given the number of similar owner reports and the cost of the remedy, I believe many affected vehicles remain unrepaired and in service.

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.

I own a 2022 Tesla Model 3 that is just past the 5-year/60,000-mile warranty. I bought it used from Tesla inventory and picked up my vehicle on June 1st, 2026 with ~32,000 miles on the odometer. The front passenger safety restraint system alert (rcm2_a636) first appeared on June 5, 2026. On June 15 at 64,008 miles, Tesla service confirmed the airbag alert and front passenger OCS issue. They found the occupant classification system module damaged and exposed, replaced it, and noted the passenger-side module shorting was also causing a driver-side error. Both cleared after the repair and test drive. Cost: $363. 23. The same alert came back. On July 30 at 66,475 miles they found an open in the passenger seat cushion self-capacitance trace wire and the driver occupancy sensor voltage out of range. They replaced the front passenger seat cushion trim and the driver seat occupancy sensor. Alerts cleared and the self-driving button now worked from park again which never did prior showing the issue was never fixed the first time. Cost: $930. 36. No crash or injury, but this is a real safety risk. The restraint system may not work as designed and airbags could fail to deploy properly. This exact rcm2_a636/OCS fault keeps happening to other Model 3 owners both before and after warranty on forums, and Tesla has service bulletins on the same parts, yet people still end up paying for the repairs who are out of warranty and also have their safety and life at risk. Please investigate this as this is a severe safety defect.

The front passenger safety restraint system is triggering an on-screen warning error that says service is required. This puts my front passenger at risk of death in the event of an accident. I have sent the manufacturer (Tesla) a request for service and received a confirmation of the errors with a list of parts to be replaced for a sum of $1200. 65. I understand there is a service bulletin for this issue (bulletin sb-19-20-003), but Tesla still will not fix it for free even though it is a safety issue. In the estimate, Tesla listed the following components as failure points that need to be replaced: 1) first row occupancy sensor(1099592-00-f) 2) first row - seat belt reminder sensor box clip(1130363-00-b) 3) first row seat harness assembly - right hand(1489060-03-g) 4) airbag harness retaining clip(1028053-00-a) 5) bolt,ehs,m6x19,[88],zn,smat,adh. - knee and passenger airbag bolt(1116594-00-b) 6) bolt rc m6-1. 25x26(1036655-00-a) 7) passenger airbag(1077823-00-g) 8) bolt,hf,m6x7,stl[88],zn,shldr[8x18]. (1105061-00-e).

My Tesla repeatedly displayed a “passenger safety restraint” warning related to the front passenger restraint/airbag system. Tesla service center in los gatos, California attempted multiple repairs over several visits. The first repair identified a pinched and improperly routed passenger seat harness associated with the restraint system. Tesla stated the issue was repaired and tested. The warning later returned. Tesla then replaced the front right seat harness assembly and lap pretensioner. The warning later returned again. Tesla subsequently proposed and/or performed additional repairs involving the passenger airbag, occupant classification system (OCS), occupancy sensor components, and additional seat harness components at significant customer expense. Despite multiple repair attempts and approximately $2,100 in repair costs, the same safety restraint warning still exists today. Because this issue involves the supplemental restraint system (srs), airbags, seatbelt pretensioners, and occupant classification systems, I am concerned the passenger restraint system may not function properly during a collision.

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.

An error message appears every time my husband drives. Whenever he moves the driver seat backwards, “front left safety restraint system issue” message appears on the display screen.

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.

2020 Tesla Model 3 standard range plus, VIN [xxx] restraint control module fault codes rcm_a056 and rcm_a058. Passenger front seat occupancy sensor failure triggering "service required" airbag system alert. September 2024: fault code rcm a056: Tesla repaired this issue under the supplemental restraint system limited warranty (5 years, 60,000 miles) at Tesla service latham NY (326 old niskayuna rd, latham NY 12110). January 10, 2026: fault code rcm_a058. Reported in writing through the Tesla app. Tesla scheduled a service visit for January 13, 2026. Technician assessed the vehicle in person and declined to repair, verbally stating the fault may be a one-time occurrence and to monitor and return if it continued. April 2026: fault continues recurring. Tesla service latham issued estimate #xxx dated April 18, 2026 for $1,076. 32 customer pay. Repairs include resistive occupancy sensor replacement and seat back trim cover replacement. This is a safety-critical system governing airbag deployment. Tesla has documented this failure mode in internal service bulletins citing electrical interference in the seat harness as a design issue. Tesla repaired this under warranty, dismissed a related restraint fault for the same seat when reported within months of the repair, and is now billing the owner for a safety system that failed due to a known design defect. A recall is warranted. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6) information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

The car has message saying "safety restraint system issue" . There has been no event to cause this. No recent mva or any stress or damaging incident to the seat belt or seat in general. Reviewing this on the internet, this is a common defect on Tesla's. The company won't fix it unless you pay them to do so which is crazy considering it is a defect in their safety system. And a well known one to them from my communication with their Tesla service centers which have a monopoly on fixing Tesla's. He said there would have to be a recall. So that is exactly what needs to happen from the NHTSA.

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.

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.

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.

This message has been intermittent and looking online has happened a lot for this model. The front passenger restraint system is critical for passenger safety, this should be a recall. Concern: customer states:alerts - seats - front passenger safety restraint system issue/service is required detected August 16, 2025.

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

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.

I received a proactive service alert from Tesla car stating: front passenger safety restraint system issue. Tesla wants to charge me to fix this and said there may be issues with the restraint system, such as seats belts or airbags if I don’t pay out of pocket to fix it. This seems ridiculous I have to pay to fix this safety concern. . Please issue a recall for this… seems a lot of people are getting this after researching on google and reddit. Thanks.

Rcm_a021 front left safety restraint system fault error.

Rcm2_a636 front passenger safety restraint system fault service is required passenger airbag turns off when a passenger is sitting in it. Error is intermittent and while occasionally turn off and on. Seems like a lawsuit waiting to happen should someone get in a car accident.

Resistive occupancy sensor consistently failing causing: -bluetooth to not automatically connect anytime the vehicle is entered - vehicle puts itself in park to prevent rollback if seatbelt is not applied - car does not recognize when driver is in seat these are serious safety concerns as it could cause a domino effect in safety features if not applied when needed.

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.

Since leasing this car in April of 2025, it has been services 8 times totaling over 30 days of down time. The issues occured in order from oldest to newest/current: may of 2025 - headliner trim falling down, unsuccessfully repaired by mobile technician June of 2025 - windows stopped working. Center console door stopped shutting. Headliner still falling down. July of 2025 - front wiring harness melted and took out the ac - the car didn't provide a single warning. The ac just stopped working. Passenger seat replaced for cosmetic defect August of 2025 - continued issues with ac and turn signal buttons December of 2025 - steering wheel rattle and clunking, suspension noises June of 2025 - suspension still rough and making grinding noises, turn signal buttons still not functioning consistently, front passenger fold down mirror shattered because the passenger seat calibration allows it to slide into the mirror. Tesla has shown zero empathy towards any of these issues. A buyback was requested, but the offer would have left us without a car and with a huge pay off. We asked for help moving into another car, and we are ghosted.

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.

Passenger safety restraint system fault error appears on and off without any correlation to driving conditions or passenger presence. This error is potentially deadly since it will cause the passenger airbag not to deploy in an accident.

My pant leg got caught on the plastic seat trim under the seat. Kept my leg trapped so I fell out of the car on the ground in the parking lot. Happened again the same day, but I caught myself before I fell. The incident caused a hole and rip in my clothing, but the rest of my body went to the ground leaving my knee and other leg caught until the end. Had a different outfit on today and it caught again! I did not fall this time either. The time I did fall I hyperextended my wrist and landed on my hip and leg, creating bruising and a sore pelvis, knee and back. Went to massage therapist soon after. Currently, following up with doctor.
