2019 Tesla Model 3 Problems

Tesla rolled out FSD 14 Lite to hardware, including to my vehicle and it’s become extremely unsafe.The past several days the vehicle will suddenly slow down/break causing people to almost crash into me, make sudden and indecisive lane changes, and constantly rocking the steering wheel left and right. I hope someone takes this seriously and has Tesla revert back to the old software or make changes before someone is killed.

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.

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 was locked inside my tesla model 3 two stories down in a parking garage with no internet access to find out where the emergency release was for my door. I KICKED my driver side window to survive. It wasn't until after I was told that the doors are tied to a 12v battery that had died without warning. I did not know the doors tied to that nor that there was a secret emergency release. There are no clear indicators within the car that this is how it operates and you SHOULDN'T NEED INTERNET ACCESS AND ELECTRICITY TO SURVIVE EXITING A CAR.

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.

Over a period of several weeks, the front suspension increasingly made noise (squeaking and groaning) and felt loose when turning and going over bumps. The front control arms were replaced 10/31/24. The problem has begun recurring over the last few months, with the same noise occurring and progressively worsening.

Front passenger Occupant Classification System (OCS) failed on its own, without accident, misuse, or modification, at low mileage. The fault disables proper airbag deployment logic for the front passenger seat. Tesla has issued multiple service bulletins acknowledging this as a known condition. **Vehicle Identification Number (VIN):** [XXX] **Model Year:** 2019 **Make:** Tesla **Model:** Model 3 **Mileage at time of failure:** Approximately 27,800 miles **Date of incident/failure:** XXX (date alert was first detected, per invoice) **Component:** Air Bags / Occupant Classification System (Front Passenger) **Crash involved:** No **Fire involved:** No **Injuries:** None **Number of injuries/fatalities:** 0 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My brake lines have corroded to the point where half a liter of brake fluid has leaked out rendering the vehicle unsafe. Tesla admits that this is a design flaw but says that it does not affect this particular VIN number but the damage is exactly as described: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The Tesla was hit on the passenger side by a Honda civic that ran a red light traveling more than 25 mph The Tesla spun 180 degrees after impact. No airbags deployed. Immediately after impact the Tesla turned on hazard lights. However the vehicle would not come to a stop after pressing on the brakes. After impact the vehicle was coasting backwards at probably less than 5-6 mph. It would not respond to brake presses. Oddly the vehicle had regen braking enabled which should have brought it to a stop, but it didn’t. The vehicle kept coasting backwards as if it was in neutral for about 20 meters until it hit a curb and stopped. BRAKES WOULD NOT WORK!!!

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.

What component or system failed or malfunctioned, and is it available for inspection upon request? The steering system failed due to corrosion and water ingress affecting both the steering rack and the associated steering wiring harness. These components were replaced by Tesla and are no longer available for inspection. How was your safety or the safety of others put at risk? The steering system is a safety-critical component. Corrosion and water intrusion created a risk of reduced or sudden loss of steering assist while driving, which could lead to loss of vehicle control and increase the risk of a crash. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Tesla service confirmed water ingress and corrosion affecting the steering rack and wiring harness and performed a full replacement of both components. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. The vehicle and steering components were inspected by Tesla at a Tesla Service Center, which identified water ingress and corrosion as the cause of failure. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The vehicle displayed steering-related warning messages prior to repair, including reduced steering assist alerts, which prompted inspection by Tesla service. The warnings appeared shortly before the repair was performed.

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.

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.

Back window spontaneously cracked. Much of the back roof is this glass, thus I am concerned that in an accident will that tempered glass hold up

We own a 2019 Tesla model 3 which had a left front headlight stop working (headlight, turn signal, and daytime running light). As soon as the headlight went out the windshield wipers stopped working. The vehicle does not have fuses but the headlight and wipers share a wiring circuit. I thought it might be a coincidence but found several of the same issues on a google search. It is beyond ridiculous that lowing a headlight at night would cause your wipers to stop working. Its bad enough to have a reduction in visibility due to a light going out but to have the windshield wipers tied to the headlight causing them to stop working is nothing short of reckless. The warning stating the turn signal needed to be serviced and to make an appointment came on when the light stopped working. I own an automotive repair shop so I ordered the headlight assembly and installed it, the lights then worked and not surprisingly so did the windshield wipers.

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.

Component: Exterior Door Handle (Front Passenger) Incident Description: A latent manufacturing defect resulted in the structural delamination of the interior chrome plating on the front passenger door handle. This failure occurred after the last use of the handle, creating a razor-sharp metallic edge that was not visible during a normal approach to the vehicle. Upon contacting the handle to open the door, a passenger sustained a deep laceration from this jagged metallic blade. Safety Hazard: The defect transforms a primary vehicle touchpoint into a concealed cutting hazard. The chrome skin peels and curls into a sharp edge without warning or visible signs of wear, posing an ongoing risk of serious physical injury to any occupant. Manufacturer Response: Tesla Service (Los Gatos) was provided with photographic evidence of the razor edge and the resulting injury. While acknowledging the injury, Tesla refused a safety-based "goodwill" repair, citing the vehicle’s age (2019) and the absence of a formal recall. Tesla further attempted to attribute this structural material failure to cleaning products, despite the vehicle being garage-kept and maintained only with pH-neutral enthusiast-grade soaps. Tesla has since refused further discussion. Request: This defect poses an ongoing risk of serious physical injury to any occupant using the handles. I am reporting this to assist in identifying a trend of material failure in 2017–2020 Model 3 chrome door handles.

My vehicle has developed a rapidly worsening battery performance issue. It loses range far faster than expected, shows inconsistent energy usage, and experiences sudden drops in projected mileage even during normal driving. Charging behavior is irregular, and the vehicle’s energy regeneration is inconsistent. There was no crash, fire, or damage. Based on the symptoms, this appears to be a potential battery or propulsion system defect. The issue continues to worsen and affects the safe and reliable operation of the vehicle.

Steering wheel lost power (in city driving) it took the driver and the passenger turning the wheel to wrestle the car to the side of the road. Turned off the car’s power after coming to a stop. The car would not start. Took 6 resets to power up the car and return it to “normal.” This is the second time the car had the steering lock up and the car not start. The first time was after shopping. The car was parked at the time. Took 4 resets to return the car to “normal.”

When Driving an Alert activates DIR_a126 Power Reduced. Exiting and re-entering vehicle may restore operation. My vehicle speed limit goes to 50 mph and keeps lowering after driving for a few miles to a creep. This alert pop up constantly.

See attached document for complaint.

Car seat is able to tip onto it's side during turns in the direction of the seat belt latch by sliding down the seat belt. My child's legs are caught between the seat belt and the back of the seat causing her injury. This occurs when installing as per manufacturer instructions without base using seat belt only. It only occurs in our vehicle where the handle does not touch either front seat and the seat material is low friction, both of which I believe contribute to the seat being able to tip. I have tried to contact Britax regarding this issue however their website contact form is non-functional. We have 2 of this model car seat and they both exhibit the same behavior.

In 2020 my driver side headlight assembly stopped working then in 2023 my passenger side headlight assembly stopped working. This includes the day time running light as well as headlight and turn signal in each assembly. No warning was displayed. This can cause confusion for other drivers and pedestrians through the inability to indicate my location or intention of travel. The first time this happened, the service center explained it was a component issue and the assembly was replaced by them. No warnings were shown from the vehicle.

Continental 235/40/r19 This is what I sent to Consumer Affair website: My personal experience reflects exactly the same as the poor rating of this brand. Tire has separation at 32k miles on the Tesla 3. I first noticed a thumb thumb sound. I ignored but it got worse then the vibration inside cabin started to occur. I pulled the tire off and inspected. My God i have a tire separation with steel wire sticking out and a big hump. I got mad after i found out that Tesla wants nothing to do with it (heck they don't even a have no. to call for an expensive car, shame on you Tesla) and Continental does not have a warranty. Spending time searching for another tire to buy i find out it is expensive for EV tire. I was frustrated and angry that i have to deal with a defective tire with no warranty from Tesla and Continental for low miles (plenty of thread left on tire). I decided to call Continental. The experience was horrible with them hung up on me and a run around. They told me to take to Discount tire to have it inspect. Dt agreed tire is defective and expect me to pay $250 with pro rate covered by Continental. I already found the same tire for $225 so i tell D.t take a hike. I called Continental back and [XXX] broke loose. I got a lot of run around, hung up with the rep. then manager and they won't do the tire pro rate more than 30%. I got fed up with lot of cussing I went back to D.Tire and settled with another Continental tire that is cheaper. I was pushing my luck driving with the tire that will blow anytime. The [XXX] Tesla does not have a spare tire on an expensive car (shame on you Tesla). I had no choice to replace a tire out of my pocket of $150 for the same brand as that is the only one with similar thread pattern very reluctantly as I had NO other choice or take a risk driving and NO spare tire.

In November both rear tires shredded, while driving. The metal belts became exposed. Tesla replaced the tires, claimed there was no other problem. The tires had been appropriately pressurized during the entire life of the tires. Mileage 9800. Two months later one of the rear tires (new tire) sustained a nail in the side wall- non-repairable (the sidewall on a new tire should not be on the pavement, but the side), and now at 3000 miles on the new tire not replaced due to the nail- the tire is beginning to shred again. This is coupled with inordinate road noise since the tires were changed. I think the problem is the car being inadequately made, and the tires, that seem to be exposing the weak sidewall to the pavement. Neither company claims credit for their handiwork.

The contact owned a 2019 Tesla Model 3. The contact stated that while driving with the autopilot feature enabled, the vehicle slid across the road and crashed into a concrete barrier. The contact stated that it was raining at the failure occurred. No Police or Fire reports were filed. The vehicle was towed to a local tow yard. The vehicle was condemned as a total loss. The contact stated after researching, the contact discovered NHTSA Campaign Number: 23V838000 (Electrical System). In addition, the vehicle was not inspected by Tesla to determine the cause of the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 20,000.

MY VEHICLE IS EXPERIENCING WIRE ISSUES RESULTING IN ERROR MESSAGES SUCH AS "POWER REDUCED, FRONT MOTOR DISABLED, ETC" THAT DISABLE SAFETY FEATURES SUCH AS THE TURNING SIGNALS AND ISSUES WITH BRAKING AND STEERING. THE VEHICLE WILL POWER OFF/SHUT DOWN WHILE DRIVING AND RESTART. THE CAR IS CURRENTLY IN SERVICE FOR THE PAST 2 WEEKS AND OTHER THAN NOTIFYING ME THAT THERE ARE "WIRE ISSUES," TESLA HAS BEEN UNABLE TO DIAGNOSE THE CAUSE OF THE PROBLEM OR FIX IT.

The contact owns a 2019 Tesla Model 3. The contact stated that while the rear seat warmer was active, a hole had burned through the seat due to the heat coming from the seat warmer. The contact stated that a blanket was placed over the seat which caused the blanket to melt and fuse into the seat. As a result of the failure, the contact had to tear apart the back of the seat where the failure occurred. The contact spoke to a Tesla service technician who gave the contact an estimate for the repair. The vehicle was not repaired. The failure mileage was approximately 78,000.
