general problems of the 2018 Tesla Model 3 - part 2

Front passenger safety restraint system fault error. They tried fixing and it started the next day again. Now they want to replace this along with my airbag. This seems to be a consistent issue reading forums online. This is a manufacturing defect and major safety issue.

Received an alert about front seat safety restraint system fault. Decided to see what was needed for the fix and address my other trunk harness recall. Received invoice stating the airbag needed to be replaced along with $1900 quote. Knowing this info, if this doesn’t get fix the safety of my passengers are at risk so now I definitely can’t have any passengers. Not sure how I should be responsible for a safety seat airbag sensor defect.

Starting Jun 15 2024 an error came up saying "left restraint system fault" after a remote software update for Model 3 2018 Tesla the alert comes up intermittently & Tesla requires $359. 50 to change first row seat harness assembly - left.

Started receiving error rcm_a056 front passenger safety restraint system fault. The vehicle shows that the passenger airbags are disabled after the alert is issued. I am working under the assumption that all passenger airbags (front, side, overhead) are currently disabled at all times. This puts my family at risk if there were to be a collision. Tesla seems to know exactly what the problem is because the estimate came back shortly with a list of fixes required at a cost of $1,768. 35 to 1) correction: install an occupant classification system (OCS) filter module, 2) correction: retrofit sbr in OCS equipped front passenger seat - remove and replace, and 3) correction: replace front passenger airbag and update vehicle configuration - remove and replace. Quick internet search shows this is a systemic problem with a bad part (Tesla forums and search your own databases for the past year or so. . . These are the people who know to report this to you, there are probably a lot of others). I'm 6 months out of warranty for a sensor that should not have wear and tear. Furthermore a retrofit demonstrates that they are replacing a known problem part. Additionally, there is no rational reason to replace a perfectly good airbag. Replacing the airbag because it is incompatible with a retrofit sensor should be free. Retrofitting a sensor that has a known problem should not be a cost to the consumer for a part that is not subject to wear and tear. Adding a filter to a sensor line shows that the sensor is not an appropriate part or the filter should have been added to start with in original manufacturing. Note Tesla has a procedure already out to address the problem sb-23-20-002 which shows they already know it is a problem that needs to be addressed when the sensor failure shows up. Recommend and request an investigation into whether there is a lower cost fix for what seems like a known problem or require a recall to repair to a safe state.

My 2018 Model 3 started giving me the error "rcm_a056_passengerfrontocs" today. This is caused by a faulty passenger occupancy weight sensor. This has been an ongoing issue in these models evidenced by sb-23-20-002 being revised 6 times. Tesla has resisted fixing this safety issue because the air bag also needs to be replaced to maintain compatibility with the redesigned occupant classification system (OCS) weight sensor evidenced in Tesla sb-23-20-001. Tesla has redesigned the known bad sensor part no. Part 1121234-70-b with an updated part no. 099592-00-f which is only compatible with an updated airbag. The OCS weight sensor was defective from the point of manufacture. The rcm_a056 error only appeared after applying the latest firmware update that addresses NHTSA recall 24v-376. The firmware update made the firmware more sensitive to analog sensor readings which revealed the originally defective OCS weight sensor triggering the error message. Nearly half of the recent NHTSA complaints for this model involve this exact issue. This OCS hardware sensor was always defective and poses an ongoing safety concern. The defective system never should have been approved as it did not function as intended originally. The NHTSA must issue a new recall that covers the defective hardware instead of just the software as in NHTSA recall 24v-376. Without corrected hardware the OCS system will not work as intended which is allowing the airbags to prevent injury and death in the event of collision. Https://static. Nhtsa.

The car issued me a "front left safety restraint system fault" saying service is required. The code it flashed was rcm_a021. I am able to get the code to go away by adjusting the seat, however, if I shift my weight or I hit a bump in the road, the warning will appear once again. This leads me to believe that there is a component in the seat that is defective. I took vehicle to the Tesla service center where they found a "broken wire in the pretensioner connector" and they replaced the wiring harness. Upon doing investigation it appears that there are multiple components that are used to determine the firing intensity of the airbags should they go off. If either are damaged the airbags will not fire correctly. Some of these components can be easily damaged due to the seats constant back/forth motion if the easy entry mode is enabled on the car. As the car was outside the warranty period, Tesla refused to cover the costs for repair even though there was a TSB (technical service bulletin) already out on this same issue (reference sb-21-17-005). Total cost for repair including parts, labor and tax was $631. 10.

I'm receiving an error "front passenger restraint system fault". According to online forums, this issue is prevalent amongst many Tesla vehicles. This seems like a serious defect that Tesla should be responsible for fixing.

My car started giving me an alert for a "front passenger safety restraint system fault". There has been no accident to cause an issue. I'm being told by the service center that it is a known occurrence and certain models/years, require a new safety vent type front passenger airbag to maintain compatibility between the front passenger seat and the front passenger airbag.

Passenger airbag and seat are faulty. Received error message on my car “front passenger safety restraint system faulty”. Tesla is wanting to replace the airbag and passenger seat and seat belt and it will cost few thousands dollars.

The vehicle showed an alert "front passenger safety restraint system fault/service is required". The vehicle never had an accident, nor abnormal usage, which may have caused this system fault. The manufacturer's service department gave a repair plan including an air-bag replacement at the owner's cost. It is not fair to force vehicle owners to be responsible for the cost to repair the manufacturer's safety system problem. The repair should be done under a safety recall.

A defect in manufacturing causes the seat sensor (in this case: passenger) connection to fail. The connection has no retaining clip and falls out. This disables the airbag deployment calculations. Error code: rcm_a056 telsa wants to replace seat and calibrate airbag at consumer's cost, quoted ~$1500 I've pushed the connector back in several times over the past few years, one day it's going to hurt someone.

Front passenger seat restraint safety system fault. My car only has 40,000 miles is out of warranty. $2200+ estimate from Tesla. This safety issue happens often according to Tesla owner sites.

My car has 98,000 miles and out of warranty. When driving 10 days ago I saw a message on the screen "front passenger restraint system fault" I took the car to the Tesla garage and was advised that it might be the air bag. They said it could cost as much as $$1,826. 66. They kept the vehicle and sent a message asking me to authorise my credit card pay this amount when done. First of all I note on the Tesla motors club that I am not alone. Second I have to rely on Tesla being honest about this. They have their own propriety testing system so I could not take it to another mechanic. Last of all I have never experienced a failed air bag in my vehicles before and it seems that Tesla has problems and this should have been paid by them as a recall item.

Experienced safety restraint system failure on all four seats. Had them all fixed for ~$2,000. Front passenger restraint failed again next month. Know. Issue among the message boards online. Investigation into number of these repairs is likely merited.

Safety restraint system fault warning, passenger airbag off on display. 1) 4/10/24 dealer replaced occupant classification system components for front passenger seat for $184. 26. Dealer assured issue being resolved. 2) 5/5/24 same fault warning, passenger airbag off on display reappeared for 2nd time and dealer replaced front passenger airbag for $1089. 18. Dealer assured issue being resolved. 3) 5/10/24 same fault warning, passenger airbag off on display again reappeared for 3rd time and dealer is now proposing to replaced front passenger seat back and seat cushions for $1248. 07.

Car displayed safety restraint system fault rcm_a094. Tesla diagnosed as rear seat buckle sensor failure. Additionally, car displays an intermittent fault rcm_a056. Tesla diagnosed this as a front passenger occupant classification system (OCS) sensor fault. Tesla stated the front passenger airbag would need to be replaced as the new sensor is not compatible with the older airbag. This renders the entire airbag system inoperable due to this component failure. The critical safety issue is extremely expensive as the incompatible sensor requires expensive airbag replacement. Furthermore, the safety system is prone to failure with 2 safety system faults occurring at <80k miles. Service rep stated that the 2018 model year has had issues with the airbag system that is why they updated the module. I asked for recall or replacement at Tesla cost but was denied. Facebook group discussions and search indicate others have intermittent OCS sensor failure and this is likely a defective part for that year.

While driving normally, an error warning was received that stated "front left safety restraint system error" and the icon for an airbag fault would come in simultaneously. This error would disappear and reappear, sometimes up to 10 times per minute, creating a driver distraction due to the loud error chime. The error code identified for the fault when checked on the Tesla service screen corresponded to pretensioner wire harness. The pretensioner harness connects the seat sensors for driver weight and positioning to the car's airbag control system, which then classifies passengers and ensures that the airbags fire correctly in the event of a collision. For example, if a smaller female driver was operating the car but was incorrectly classified as male, the airbag could fire with excessive force and cause injury. The set of symptoms occurs commonly in Tesla Model 3s and are caused by the wear over time of a poorly designed wiring harness, which chafes as the seat is moved forward and backward until it breaks. This is a known problem by Tesla and they have a specific service bulletin designed to address it, which I have attached below. When taken in to address the issue, Tesla performed the procedure in the attached bulletin and identified a damaged harness, which was subsequently replaced. I retained the damaged harness for inspection. The invoice for this service is attached. No other defects were identified that could have caused the issue. This is a safety related issue occurring due to a manufacturing related defect and should be a mandatory recall with complimentary repair.

Front passenger OCS errors - Tesla work quote (via Tesla service bulletin, not recall) is to replace the OCS system & front airbag - totaling $1,200 for the repair. This is extremely common error code for Tesla's "front passenger safety restraint system fault".

I purchased the car new in 2018. About two years into owning there would be a random notification about an "rcm_a036 : passenger safety restraint system fault". I reported and was told that the seat occupancy sensor was responding to noise from my cell phone. I stopped putting the cell phone on the seat, it kept happening with increasing frequency in 2021 and 2022 and I reported it two more times and was told to keep charging cables away from the seat, and then in 2021, they added a noise filter. I was told repeatedly that the fault was caused by noise and was not a real issue. The alert occurred with increasing occurrence and today I took it in and Tesla charged $1533. 16 to replace the airbag and the occupancy sensor. I thought it was unsafe for Tesla to tell me the issue is a noise-related issue when it was related to the airbag and to tell me that the issue was not actually a real fault when both the OCS sensor and the airbag needed to be replaced. I think it's absurd to have a car 6 years old with 66,530 miles have to have an airbag replaced. I thought Tesla's comments about noise were disingenuous attempts to put off the repair until after the car was out of warranty.

Two recent incidents/repairs related to both driver and passenger curtain airbag, replacement of occupant classification system, replacement of first row seat cushions, first row harness assembly, first row occupancy sensor, first row seat belt reminder sensor box. Total out of pocket cost of approximately $2,075!.

I'm getting an error for "safety restraint system fault" on my Tesla Model 3. When I booked a service appointment it turns out they are wanting to charge $1,955. 11 for replacing the occupant classification system (OCS) of the front passenger, updating the front passenger airbag, and installing a OCS filter module. This seems to be safety related and should be part of a recall. I have seen similar reports from other drivers on reddit.

Apparently faulty sensor that then needs to replace airgbag and now it’s costing $1833!.

Front passenger airbag and seat sensor issues. The safety of front seat passenger was at risk due to faulty airbag or sensor. Tesla did confirmed that an alert was trigger on the car an they proceeded to replaced the airbag and sensor. Tesla verified the equipment after the repairs were done and everything since to be fine. We did get a warning on or around Feb 5th, 2024 and that when we proceeded to contact Tesla service and make an appointment. The reason for this complain is that we ended up paying for airbag and seat sensor repairs which should have been covered by Tesla since these parts are obviously defective. Please see uploaded documents for more details.

The contact owns a 2018 Tesla Model 3. The contact stated that while starting the vehicle, the message "front passenger safety restraint system fault" was displayed. The local Tesla service center was notified of the failure and informed the contact the front passenger's side seat and air bag needed to be replaced; however, the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 47,000.

The airbag light shows.

I received an onboard alert that says ‘safety restraint system issue/service is required. ’ according to online Tesla forums, this is a very common issue with the Model 3 drivers side air bag system. Although some relate it to a wire under the seat that becomes worn with movement of the seat, Tesla gives an estimate of over $1,000 to fix the problem. There repair estimate involves updating the front passenger airbag ($444), and replacing the occupant classification system ($426).

There is an ongoing issue with Tesla's seat sensors that give an error screen while driving. Tesla seems to be systematically charging a standard $1. 5k repair to replace a $100 sensor harness, but they're charging so much because they claim an airbag replacement is required (for an extra $1. 2k) as part of the new sensor/wire harness installation. From a quick google search, it seems this is a pretty widespread issue that many Model 3/y owners are encountering as their car ages-- with many noting that they were able to self-service the issue with buying the required harness and replacing it themselves. I wanted to bring awareness that to this issue and Tesla's poor and systematic way of overcharging customers to fix a widespread defect in their car seat design.

I have three potential safety hazards to report. Tesla has advised that there is no recall for any of these. 1) the car issued an alert that says "front passenger safety system fault. " this seems like the most serious. 2) the horn malfunctions and does not work at safe level 3) the driver's side mirror does not consistently extend out preventing the driver from adequately using the mirror for driving.

My Model 3 began giving an rcm_a056 error indicating a fault with the front passenger safety restraint system. When I scheduled service for this fault at Tesla, they advised that the front passenger airbag and occupant sensor for the right/front seat needed to be replaced. Research into this issue revealed at it is a common issue. Other owners reported Tesla covering the cost of this repair (indicating they know this is a manufacturer defect in a major safety system and not a one-off issue. ) unfortunately, Tesla refused to repair this issue without payment, insisting that my srs warranty had expired. I believe this is a manufacturer defect in a critical safety system that should be investigated for a possible recall.

My car went out of warranty for seat related issues in December of this past year 2023. I don't even have 26k miles on my car therefore not a heavy driver. This week I experienced an error rcm_a021, front left safety restraint system fault, which I've researched has affected many others and appears to clearly be a safety flaw. The service team mentioned this isn't covered. My airbag light doesn't go off and is constantly on, my seats no longer save the seat setting (which occurred a couple of months ago but I didn't think about it). This is a safety hazard should I get into an accident. There were no previous warning issues prior to this warning error which occurred this week. According to Tesla, if the airbag light remains lit, schedule a service appointment immediately and do not drive. The service team mentioned the seat harness is faulty remotely and according to what they can see. I have not had them look visually yet though. They do not cover the repair for this as it's out of warranty. There's even a bulletin posted on this issue/repair by NHTSA therefore is known problem. Https://static. Nhtsa. Gov/odi/tsbs/2019/mc-10169819-9999. Pdf I'm unable to upload any files.

When driver seat adjusted to end positions (e. G all the way up/down/forward/backward), it causes an error message stating “front left safety restraint system fault” & and airbag failure icon would appear. This usually cause by the wire harness being pinched or stretched. The error message may come and go based on the position of the seat, and occurs more frequently as time goes by. I am concern that the airbag or other safety restraint system may fail to engage when the message pops up. Tesla community has reported similar failure.

Airbag failed at 60k miles requiring a replacement. This is a known- safety issue, Tesla has corrected this problem in later cars, and Tesla should issue a recall to correct. I have error codes rcm_a015 and rcm_a014.

I had a seat weight sensor error. Took into repair and the replaced sensor and then informed me they need to replace airbag because it’s not compatible with the new sensor. Then was told that it would cost $1100 more than estimate to replace an airbag that is in working condition. Tesla purposely replaced sensor that was not compatible with the way they built the car and expect consumer to pay for it.

Intermittently over the past two months, the vehicle has been showing error code rcm_a056 with the accompanying message: front passenger safety restraint system fault service is required I reached out to Tesla and the service estimate was nearly $1500 to replace the airbag "to maintain compatibility with front passenger seat" for $942 and $414 to replace the occupant classification system (OCS) of front passenger seat plus taxes. Basically, they want to replace the airbag and the seat sensor system. Many people on the forums have reported the same issue, which is sometimes fixed by replacing both components, just the sensor, or reseating the sensor cable. This is clearly a safety issue caused by a defect and these critical components should not fail this catastrophically in just 5+ years.

I kept getting notifications indicating that there was a front passenger safety restraint system fault - rcm_a056. On reaching out to Tesla service, I received an estimate for more than $2000 to fix and they appear to be replacing the seat, occupant classification system or sensor, and also front passenger airbag. I found many instances of this issue on online forums(with different error codes) and I am worried that this may be a widespread safety issue related to the seat belts or corresponding components which may prevent them from detecting occupants or failing to prevent injury in case of a crash.
