2019 Tesla Model 3 Owner Complaints

The vehicle reported an error with steering. I brought the vehicle into tesla service. Upon inspection the connector to the steering rack was heavily corroded from water intrusion and had broken clean off upon removal. Confirmed with dealer that corrosion had caused the issue. If the connector had failed while driving the vehicle would have lost all power steering immediately and placed myself and others on the road in danger. The connector was corroded enough that the spade connector detached completely upon inspection. The steering rack is not easily accessible by the consumer and could not have been impacted by circumstances outside of normal driving.

On September 12, 2026, at approximately 2:05 PM, while operating on Full Self-Driving (FSD v14.1 Lite) on Hardware 3 (HW3), the vehicle experienced a critical, unprompted loss of path control. While traveling on the highway, the vehicle sharply veered off the left side of the roadway, caught air, and violently impacted an emergency barrier, resulting in the destruction of 9 steel poles and causing physical injuries to both the driver and front passenger. Despite the severe frontal impact and structural collision, neither the front nor knee airbags deployed, raising serious concerns regarding the vehicle's crash-sensing algorithms, structural impact detection, and restraint system integration under this software version. This incident highlights major safety risks associated with running computationally heavy FSD stacks on legacy HW3 architecture: 1. Uncommanded Steering Deviations: The system abruptly executed a violent, unprompted hard turn away from the path of travel, indicating severe lane-detection or path-planning failure. 2. Restraint System / Safety Failure: Critical secondary safety systems (front and knee airbags) failed to deploy in a high-impact structural collision involving multiple steel barrier poles. 3. Hardware Constraint Risks: The compounding computational and thermal load on HW3 hardware running v14.1 Lite continues to manifest in erratic vehicle control, latency, and hazardous tracking behavior. This severe safety defect requires an immediate federal investigation into both FSD trajectory control on legacy hardware and secondary restraint deployment failures.

Tesla FSD made Left Turn on Red Left-Turn arrow: On August 12, 2026, at approximately 4:30 PM, my 2019 Tesla Model 3 was operating in Full Self-Driving (FSD) mode at the intersection of US-71 West and Pedernales Summit Parkway in Austin, Texas, 78738. The vehicle proceeded to make a left turn while the left-turn traffic signal was displaying a red arrow. This was an unsafe traffic-control violation and created a potential collision risk. I had to monitor the vehicle and be prepared to intervene. I am reporting this as a safety issue with the vehicle’s automated driving/Full Self-Driving system. I also reported this issue to the Tesla through my Tesla APP but no action was taken from them. They have not even called and asked for this issue. I would request you to investigate this matter promptly and provide a detailed report on how this simple mistake could happen with the software.

Incident

Aug 12, 2026

The Restraint Control Module (RCM) fault code RCM_a056 intermittently appears and disappears on the vehicle's display. This code indicates a fault in the front passenger Occupant Classification System (OCS) — the sensor responsible for detecting passenger presence and weight to determine whether and how the passenger airbag deploys in a crash. Because the OCS sensor is malfunctioning, the passenger airbag may fail to deploy, deploy incorrectly, or deploy with wrong force in a collision, putting any front passenger at serious risk of injury or death. The fault is intermittent — it appears and disappears without any change in vehicle configuration or seating — which is consistent with a failing OCS sensor or degraded wiring harness connection under the passenger seat. No collision or injury has occurred. The vehicle has not yet been inspected by a dealer or service center. No independent inspection has been performed. Tesla has issued Service Bulletin SB-23-20-002, which has been revised at least seven times, acknowledging a known OCS sensor defect across multiple Model 3 vehicles. Despite this, no safety recall has been issued. The repair cost quoted by Tesla service is approximately $800–$2,000 out of pocket for what appears to be a widespread manufacturing defect in a critical safety system. Numerous other Model 3 owners have reported the identical fault code. The component is available for inspection upon request.

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.

To Whom It May Concern, I am logging a safety defect complaint regarding my 2019 Tesla Model 3, which displays active fault code RCM_a056 – Front passenger safety restraint system fault. This error deactivates the front passenger airbag and seatbelt pretensioners, creating an immediate, severe safety hazard. The Defect: The failure involves the Occupant Classification System (OCS) seat sensor and affects passengers in two ways: 1. Children (Current Stage): The fault triggers primarily when a child sits in the front seat. The degraded sensor mat cannot process lighter weight accurately, throwing an "implausible voltage" error that disables the airbag system. 2. Adults (Advanced Stage): online data shows this same code eventually locks out for adults due to internal wiring harness fraying or sensor circuit failure. Manufacturer Response: Tesla is aware of this fleet-wide defect and issued Service Bulletin SB-23-20-002 to address it. However, because my vehicle is out of warranty, Tesla refuses to cover this critical safety repair. Service centers are quoting owners $1,300 to $1,500+ out-of-pocket to fix an inherent manufacturing flaw in a federally mandated safety system. I urge the NHTSA to investigate the 2019 Tesla Model 3 OCS system and compel Tesla to issue a safety recall to fix this hazard at no cost to consumers.

Tesla recently introduced auto parking as part of its FSD technology (Software 2026.20.6.11). Whenever we set the car destination to “home”, the auto parking has been able to gradually maneuver the car and self park in our garage. On 8/11, around 8:30pm, the car made a mistake during the auto parking. During the auto reverse into garage, the car came too close to the side of the garage and the driver side mirror hit the wall and partially broke. The driver was monitoring the car. If the car has kept its angle, it would have made it through correctly. But looks like it miscalculated and in a fraction of a second, the car’s side mirror hit the garage wall. Given the “ park” feature is new, looks like it hasn’t been tested well. It should be recalled until it is fixed and impacted drivers should be compensated for their repairs.

Noise came from front left wheel while driving around a turn. Later the same day another noise when turning the wheel when leaving a parking spot. Steering felt strange. It was late at night, so left the vehicle until the morning. In the morning, discovered a large bolt in front of the vehicle. The front left wheel was turned differently than the right front wheel. Had to spend almost $400 to get the vehicle towed to a Tesla service center. They later confirmed, "The cause was detached links from the bushings and bolts. Technician replaced the front lower lateral links, front lower compliance links, and front stabilizer bar bushing brackets. Total cost for those repairs was $1,902.90. This could easily have resulted in an accident and even a fatality if we were not so lucky.

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.

Between 2023 and 2026, I have had several clunking and creaking sounds from the suspension. These were then found isolated to "lateral and compliance link detachments" and Tesla noted these were "serious safety issues" and fixed them out of warranty at a cost of roughly $2500. When I pointed out that vehicles within this model range (manufactured April 2019 at the Fremont, CA plant) were flagged for a recall, they mentioned my vehicle was outside that range and insisted on an out-of-pocket repair. Further, I have similarly had to have the front left driver's side seat belt harness replaced because of a restraint control module failure. I have owned 3 other vehicles and have never had a restraint control module/seatbelt fail over just 82000 miles of use.

Honestly since I took delivery the vehicle I did notice a clunking sound every time I would turn into a steep driveway. I reported the problem to Tesla on multiple occasions and they either could not replicate the sound or find the problem when they inspected the vehicle. So I lived with the on and off clunking sound. Years later while driving on the freeway I heard a really hard clunk and I began to lose control of the car luckily I was close to home and I was able to make it to my street. Upon arrival my tires completely fell off the control arm and I could move the steering wheel at all. I had to get it towed to the body shop. Long story short the lower control arm bolt completely fell off. I just happy this didn’t result in a major accident. But I had to get the car towed. I am pretty upset that Tesla pretty much said there is no issue. My family has Teslas and in all of them I hear the same clunking sound.

About one month ago, my 2019 Tesla Model 3 developed a suspension issue that caused a noticeable vibration in the rear of the vehicle whenever I drove above 40 mph. At first, we suspected the problem was related to a tire. However, after the technicians at the Tesla Service Center lifted the vehicle for inspection, they discovered a much more serious issue. They brought me into the service area to show me that the right rear suspension was being held together by only the front portion of a bolt. The retaining nut had completely come off, leaving the bolt barely in place. Had that bolt shifted even a few millimeters while I was driving, it could have resulted in a catastrophic suspension failure and a serious accident. Tesla determined that the loose bolt had caused damage to the right rear (passenger-side) suspension assembly. The necessary repairs totaled approximately $1,800, which I paid to restore the vehicle to safe operating condition.

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.

Summary of the Problem Rear subframe assembly and multiple rear suspension links required full replacement due to failure/wear at approximately 51,890 miles, on a vehicle with no history of collision or accident damage. Tesla diagnosed the issue as an interior rattle/squeak reproducible over bumpy roads and speed bumps, which led to replacement of the rear subframe and nearly the entire rear suspension link set. Total repair cost was approximately $7,667.65, entirely out of pocket, as Tesla stated no recall applies to this VIN. Full Description (detailed narrative field) In December 2025, I began noticing a rattling/squeaking noise from the rear of my 2019 Tesla Model 3, reproducible on bumpy roads, speed bumps, and rail tracks. The vehicle has never been in an accident and has no history of collision damage. I brought the vehicle to Tesla Service (Fremont, CA) on 07-Jan-2026 at 51,890 miles. Tesla's diagnosis found it necessary to replace: The rear subframe assembly Rear toe link assemblies (left and right) Rear upper fore link assemblies (left and right) Rear lower fore link assemblies (left and right) Rear upper aft link assemblies (left and right) Front lower compliance links (left and right) Front lower lateral links (pair) A four-wheel alignment This amounted to nearly a full rear (and partial front) suspension rebuild, at a cost of $6,843.34 for this job alone, and $7,667.65 total, entirely at my expense. Tesla confirmed there is no open recall covering this VIN or this failure. I am concerned this represents a premature structural/suspension component failure unrelated to accident damage or normal wear, at a mileage (51,890) that suggests a potential defect in the subframe or suspension hardware/corrosion resistance for this model year, rather than an isolated wear item. I am filing this complaint so NHTSA can evaluate whether this is part of a broader pattern for 2019 Model 3 vehicles.

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 was using Full self driving (FSD), but I notice the autopilot gets "impatient" when (correctly) stopped for a "long" period of time (~2 minutes), but will then try to proceed in dangerous conditions. 1. I had FSD engaged while waiting to make an uncontrolled left turn. The street I'm turning onto is busy, so both lanes are going at a steady pace. After about 2 minutes of waiting, the autopilot decided to make the left turn while BOTH directions had cars approaching. It turned towards a motorcyclist (which might be why it thought the lane was "empty"), and cut off a rather large car behind the motorcycle which almost caused a collision. I was honked from both sides (rightfully so) and put in a very dangerous position as my car was now stopped in the middle of the row of both lanes. 2. I was at a red light intersection with no traffic coming from either side with FSD engaged. After about 2 minutes of waiting, the car tried to go on its own while the light was still red. After manually stopping the autopilot, the light naturally turned green a few seconds later.
