What 982 owners told NHTSA about the 2018 Tesla Model 3 Bev

My hard brake lines were corroded and had to be replaced on a 7 year old model 3 with 70k miles on it. The cost was over $4000 as battery has to come out and it's very labor intensive. Tesla offered no help with paying for this. They tried to say the car probably was in a very corrosive environment before I bought the car (I purchased it about a year ago). However, I've seen little to no corrosion anywhere on the car. I've decided to report this issue after talking with several lifelong mechanics who have said they have never heard of hard brake lines failing on a car with age and mileage that mine has. Also after searching owner groups I've heard from other owners that have had this same issue and it seems like a growing number especially in early model 3 cars. I was giving a warning about low brake fluid and advised not to drive the vehicle before getting it inspected.

I was driving with Full Self Driving active on Sunday morning and my car came to a complete stop at a red light. Once the traffic cleared the car drove right through the red light and I was given a traffic citation by a police officer. The car did wait until there were no other cars present so I don't believe I was in any real danger but the fact that the car went through a red light while on full self driving violates the rules of the road which as we know is illegal. I have a video from my dash cam but this form doesn't appear to allow for video uploads.

Error code RCM_a021 front left safety restraint system fault. An issue that arises purely due to poor seat design. It is the fault of the seat pinching a wire from moving back and forth. This safety issue is an inevitability and not a one off chance. This issue is publicly noted on forms throughout all the years of this car’s production. This error results in airbags not being properly deployed in the event of an accident and the car not properly reading the passenger occupancy.

The front lower lateral link (rearward lower control arm) fastener/bolt completely backed out and fell off the vehicle while in motion, causing the lateral link to separate entirely from the subframe. This is the exact mechanical failure described in Tesla Recall Campaign 23V-235 (Service Bulletin SB-23-31-001), however, my specific VIN was not included in that recall. The vehicle and components are currently at an independent EV repair facility and are available for inspection upon request. Photographic evidence of the missing bolt and separated control arm has been retained. The separation of the lower lateral link caused an immediate and violent collapse of the front passenger-side suspension geometry. The affected wheel was no longer anchored to the vehicle frame, causing it to fold backward and grind heavily against the wheel well. To keep the vehicle moving straight, the steering wheel had to be turned to an extreme 45-degree angle. This resulted in a near-total loss of steering control. Had this fastener failed while traveling at highway speeds instead of low speeds, it would have resulted in an uncontrollable, catastrophic collision. Yes. The problem was physically confirmed and documented by an independent, EV-certified repair facility (EVFixMe/Shocker Motors in Costa Mesa, CA) once the vehicle was placed on a lift. The vehicle was physically inspected by an independent service center. The manufacturer (Tesla) was contacted via the Tesla App; however, they refused to perform a physical diagnosis without pre-authorization of a 2,600 comprehensive suspension replacement estimate and stated the vehicle was out of warranty with no open recalls. There were no dashboard warning lamps, digital alerts, or error messages from the vehicle's computer system prior to the failure. The failure presented suddenly as a loud, painful metal-on-metal grinding noise accompanied by immediate, severe steering misalignment. Currently waiting on invoice from indy shop.

There is no checkbox for Full Self Driving (Supervised): 3 times in the last 4 weeks, my Tesla has become impatient at long red lights and lurches out into the intersection. I am very concerned because one of those times (first time) it did not creep forward, but just took off thru the red light. I had to accelerate thru to get ahead of those cars that still had the green light. Fortunately, nothing untoward happened, except scaring me! The other two times, I recognized what was happening and put on the brakes and removed from FSD mode. I have complained to Tesla and am asking for them to verify my FSD is up to date and this issue will be fixed. Needless to say, I have stopped using the FSD (Supervised) until this is all addressed.

Description of the Defect: While driving with Full Self-Driving (FSD) engaged, the vehicle's primary computer shuts down and reboots, causing a sudden loss of all safety features, including Blind Spot Monitoring, Lane Departure Warning, Forward Collision Warning, and the driving visualization. The cameras go black while the vehicle is in motion. The Trigger: The failure is triggered by high electrical load. If the Cabin Heater (HVAC) and Seat Heaters are active while FSD is fully computing, the 12V power supply to the computer drops below critical voltage, causing a "Turbo A" processor lockup and system crash. Evidence of Defect: Service Center diagnostics confirmed the specific error code APS_w169_TurboA_SCS_LKUP (Computer Crash) occurred at the exact same timestamp as VCLEFT_a302_blowerGeneralFault (HVAC Blower Failure). This proves a common-mode voltage drop affecting multiple critical systems simultaneously. Manufacturer Response: The manufacturer (Tesla) acknowledged the logs but refused to inspect the wiring harness or ground connections, instead recommending a replacement of the computer unit. However, the failure can be mitigated by unplugging external cameras to reduce load, proving the root cause is an insufficient power delivery design (Wiring/Grounding) rather than a component failure. The computer is running at full load with the newest FSD software and it can no longer keep up with additional loads. Safety Risk: This defect causes a sudden, uncommanded loss of driver assistance and situational awareness tools (cameras/visualization) while the vehicle is maneuvering in traffic. The vehicle’s power distribution system appears insufficient to support the electrical load of the software (FSD) and the hardware (HVAC) simultaneously.

The rear doors are not equipped with manual door releases. In the event of a crash or fire the rear seat passengers would be trapped and would only be able to exit over the front seats and front seat passengers. If the front doors were damaged or front passengers incapacitated the egress for the back seat passengers would be severely impacted. If a fire would occur the situation would be exacerbated. Tesla corrected this condition in later models by installing cable releases for the rear doors. Tesla has not responded with any positive response to our request to provide an upgrade and manual rear door releases.

My 2018 Tesla Model 3 started squeaking at 36k miles at the end of 2023 (5 year old) I took to the Tesla service center where they quoted me $570. The squeaky control arm issue in Tesla is well known on the internet with may forums complaining about it. Not sure if there is a safety issue but wanted to report this incase there is a pending case regarding this issue. I was happy to pay for parts but the $570 seem excessive for a 5 year car that had 36k miles.

After downloading Tesla’s update (no. 2025.44.25.4) software my heater (with the window defrost functionality) in winter stopped operating. I made my update while at my nearest Tesla service compound (location verifiable per system location log) on 01/25/26 when that same day software began throwing HVAC error codes with blowing cold air, when previously my heat ran well. This is not coincidental; this is system design failure.

The front control arms are creaking and I’ve read that many of models built in 2018 have this problem as well. It is unknown if it is a safety concern or not.

The front and rear windshields of my Tesla Model 3 developed long cracks requiring full replacement. For over six months, I have been unable to complete these replacements due to repeated failures in the replacement process. The vehicle and damaged glass are available for inspection upon request. My insurance claim was filed with Esurance, and Safelite AutoGlass, Esurance’s designated auto glass provider, has handled all replacement attempts. During this period, three shipments of glass arrived damaged and two shipments were the incorrect glass for my vehicle, resulting in canceled or rescheduled appointments. Safelite has documentation of these failed attempts. Driving with cracked front and rear windshields puts my safety and the safety of others at risk. The damage impairs visibility, especially in rain or low-light conditions, and compromises windshield integrity, which is critical for vehicle structural support and proper airbag deployment. The rear windshield damage also raises concerns about sudden glass failure while driving. The issue has been reproduced and confirmed multiple times by Safelite AutoGlass, an independent service center. While waiting for service, I personally spoke with several other Tesla Model 3 owners at Safelite locations who reported similar experiences, including multiple failed appointments, incorrect glass, and in some cases incorrect installations requiring return visits. This suggests a broader, systemic issue rather than an isolated incident. The vehicle has been inspected multiple times by Safelite AutoGlass, and the issue is documented through Esurance claim records and follow-up complaints I submitted regarding the prolonged lack of resolution. Tesla has not directly inspected the vehicle. There were no warning lights or system alerts prior to the issue. The problem presented as visible cracks that appeared and progressively worsened, prompting replacement attempts beginning approximately six months ago.

Safety Restraint Warning appeared on a 50k miles Tesla Model 3. We are a used electric vehicle dealer in California. This warning has been appearing on parked vehicles repeatedly. Meaning, many of the Model 3's we have listed for sale (over 30 units for sale at any given time) will suddenly have a "Safety Restraint Warning" appear. Tesla is not taking responsibility for this. They always charge the customer. The airbag system is inoperable with this warning. It's a problem on EVERY Model 3 on the road between the year of 2017 to 2020.

I purchased this car new in 2018 and recently replaced the front lateral suspension arm due to worn bushings. During the process, I discovered that one of the 14 mm bolt threads on the right side of the suspension arm had a helicoil inserted. While removal was straightforward, reinstalling the bolt proved difficult. I spent several hours reattaching it to the new suspension arm, but did not apply full torque, as I was concerned about damaging the helicoil or stripping the thread. My main concern is that the factory has stripped the original thread and used a helicoil instead of replacing the affected part. Although the repair has held so far, I am unsure if this is a safe long-term solution, as the helicoil could fail while driving. I contacted Tesla, who advised me to visit their service center. At the Centinela location in Los Angeles, the supervisor informed me that, since the warranty has expired, they can only perform a visual inspection.

Vehicle is 7 years old with 107,000 miles. I received a warning regarding low brake fluid with instructions not to drive the vehicle. Dealer is advising all brake lines are rusted out and need replacement. Rusted lines are apparently causing the brake fluid to leak. I've never heard of any vehicle, let alone a 7 year old vehicle, needing all brake lines replaced. After researching online, my 2018 Tesla Model 3 is not the only Tesla Model 3 with this issue. Specifically, it appears some early 2018 Model 3s have suffered this issue. I believe this is a design defect and safety issue, and that Tesla should be voluntarily repairing affected vehicles with this known issue, since it is a design/safety issue.

The front suspension control arm was completely detached due to unfastened bolts. While this happened on the parking lot at low speed, such detachment at highway speed would certainly lead to major damage, loss of control and injuries or death to the driver. Pictures attached show that the bolts did not have any thread lock applied and simply unscrewed themselves due to vibration. The vehicle was brought to Tesla service, where the owner was charged $3700 for repairs. The customer's complaints that this is a structural/manufacturing problem were ignored by Tesla representatives.

Hello, I have a Tesla model 3 that I bought back in 2018 . On [XXX] when I sliced my finger while opening the door, because the chrome coating on the door handle started peeling. The cut was very deep ( see attached pictures). I contacted Tesla for resolution and they said that the car is not under warranty and I have to pay $340 for each handle to replace them. Apparently the peeling chrome happened to many other Tesla 3 owners and the company is aware of it and they told me that it might be caused by the car washing detergent (?!!) I think it was a defective design and the peeling chrome coating is a major health hazard. The child cand slice their fingers and if person has a bleeding issues and cut themselves while on the road it can be bad. I think it should be treated as a recall for bad design and should be fixed for free. I lost couple of days of work since I work in the Operating room and my finger was severely cut. I will wait for your response, thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1.The component that failed is the load index rating and both inner and outer sidewalls of the tire. Yes, the tires are available for inspection, they are off the car and stored in my garage. 2. I believe the safety of others and my self were at risk, I went for a tire rotation and saw the damage and asked the shop if tires were good and they said its good. Later my father points out this will kill me, so I went back and they offered the replacement warranty with that "tire is free and clear of all liens" claim. :( I refused to sign after reading and bought new tires at tesla and kept the old ones in storage. Also would like to note there website has a gap on warranty manual year after January 1, 2021 to before January 1, 2024 so I'm assuming the newest one is in play. Overall, the safety of others mainly heavy cars like Tesla's are involved. Also the local manger spilled to me that these tires are on Hertz and Enterprise cars, but they might be lighter/cheaper versions then mine. 3. Yes, tesla Tech in Libertyville IL informed me this is a problem and to read my user manual and double check the load index rating. All of which check out correct and don't sound any alarms. 4. no, only firestone and Tesla inspected the tires. 5. No, no warnings besides the cracks forming and getting bigger in the cold weather. Only visual inspection or leak might warn others, but I fear the leak is too late unless parked. Tire size: "235/45R18 94W M+S" from the actual tire. Now that I'm looking at it they are missing the 'P' for passenger.

I have an active alert on the drive side safety restraint system. Alert code RCM_a021. I have noticed this appears to be a common problem. A recall should be issues as this a a safety issues and lives could be at stake.

I received a safety alert on my car screen: Front passenger safety restraint system issue. Service is required. The front passenger safety restraint system fault typically involves a malfunctioning occupant weight sensor in the passenger seat, which controls whether the airbag activates or deactivates EVGOER. This is a serious safety concern because the airbag may be disabled at that seat location in the event of a crash. The issue is often caused by loose, broken, or unplugged harnesses or connectors under the seat, particularly related to the Occupant Classification System (OCS) Tesla Owners OnlineDigital EV Doctor. Many owners report this happens because wires under the seat get crimped over time due to Tesla's "easy entry" feature that automatically moves seats. Since this a widespread Tesla Model 3 problem, I believe this should be a recall.

I am reporting a major safety defect that began immediately after Tesla installed the Full Self-Driving (FSD) hardware upgrade on my vehicle. After paying $2,000 for FSD and receiving the hardware retrofit, the car now instantly veers left toward oncoming traffic whenever FSD is engaged. This began immediately after Tesla’s installation. Before this service, my vehicle operated safely. I have contacted Tesla Cherry Hill Service Center in New Jersey multiple times. The advisors there repeatedly told me to “just recalibrate the cameras from the touchscreen.” I’ve done this numerous times, following every instruction carefully, but the issue persists. When I called the Service Center, I was told that “everything looks fine remotely,” even though the problem continues and is clearly dangerous. I was also told they could take it for a test drive, but that if they couldn’t find anything, I would have to “wait for a future update” to make FSD usable. This is unacceptable and unsafe. Tesla delivered this car to me in a dangerous condition that could easily cause a serious crash. A car that steers itself into oncoming traffic under FSD control should never have been returned to a customer — especially one new to using FSD. I should not be responsible for any repairs, recalibrations, or diagnostics related to a defect introduced by Tesla. This issue appears to be the direct result of improper installation, misalignment, or faulty calibration following the FSD hardware upgrade performed by Tesla Cherry Hill. This poses a severe risk of collision and injury, and Tesla’s refusal to take responsibility or correct it under warranty demonstrates clear negligence and disregard for safety. Tesla Cherry Hill is also known for poor customer service and repeated dismissal of safety complaints from other owners, which further concerns me.
