2023 TESLA MODEL Y Complaints

My 2023 Tesla Model Y has produced concerningly loud mechanical noises while parked, plugged in, and not being driven. I’ve experienced this on two separate occasions—[XXX] and [XXX]—after the vehicle had been parked for several hours in a garage. Upon waking the car (without driving it), it emitted a very loud and persistent mechanical sound, both while plugged in and even after unplugging. The volume and intensity of these sounds were far beyond normal operation and raised immediate concerns of overheating, component failure, or an underlying safety defect. The experience felt unsafe enough that we considered exiting the vehicle both times. We attempted to schedule a service appointment through the Tesla app, but received no response, and the request appears to have disappeared with no record remaining in the app. Based on the nature of the sound, we’re unsure what it could be, and may indicate a malfunction in the cooling system or battery thermal management. I have video documentation of both incidents, along with video from other nights with similar temperatures where this did not occur, for comparison. I’m submitting this report out of genuine concern for vehicle safety and reliability, especially given Tesla’s known issues with thermal and battery behavior in high-heat conditions. These noises began recently, and we have owned the car since 2022 and have driven it consistently in high Texas heat every summer. This suggests a new or developing malfunction, not a feature of normal operation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The bolt that connects the control arm to the vehicle chassis fell out of the care (and was recovered) and the mechanic noted the other bolt was also very loose.

Front Passenger Seat Occupancy Sensor Defect – Tesla Vehicle In March 2025, my Tesla vehicle began displaying a warning message indicating a fault in the front passenger seat occupancy sensor system. I brought the car in for service on March 14, 2025, and the system was reportedly replaced. However, in April, the issue recurred — the seat sensor alarm would activate randomly, particularly after going over bumps, falsely indicating that a passenger was present when the seat was unoccupied. I returned the car to Tesla service, and they again claimed to have repaired the issue. Despite this, the false passenger occupancy alerts continued. In May, I contacted Tesla and submitted several videos clearly documenting the problem. Tesla performed a remote diagnostic and stated that the seat occupancy sensor was functioning as intended. On June 22, 2025, I brought the vehicle back in for in-person inspection. Tesla physically examined the vehicle and acknowledged that the false alarm could be reproduced in a similar model vehicle, effectively confirming a design defect. Despite this, Tesla maintained that the issue did not affect the safety or function of the front seat. I believe this defect presents two significant safety concerns: 1.The frequent false alarms are distracting during driving, increasing the risk of an accident. 2.The defect raises serious concerns about the reliability of airbag deployment and other safety systems, which rely on accurate seat occupancy detection in the event of a collision. I have video evidence and service documentation supporting the timeline and recurrence of this defect. The problem has been reviewed multiple times by Tesla service teams, both remotely and in person. Tesla has acknowledged the issue can be reproduced but has taken no corrective action. I have videos of the defect I can submit and documentation of my conversations with Tesla.

I am writing to raise a safety concern regarding the use of Tesla’s Full Self-Driving (FSD) system on my 2023 Tesla Model Y when a rear hitch-mounted bike rack is installed. Numerous users, including myself, have experienced dangerous or erratic behavior from FSD when carrying bicycles on a rear-mounted rack. Specific issues include: False detection of a trailing vehicle directly behind the car. Phantom braking or swerving, including abrupt lane changes or acceleration. Unreliable navigation at intersections (e.g., nearly running stop signs) due to apparent misinterpretation of sensor data. In some cases, tailgating or aggressive following behavior by the vehicle. These behaviors appear to stem from the FSD system misinterpreting the presence or visual signature of the rack and bikes as another vehicle. In several online reports, this has led to unsafe maneuvers. To temporarily mitigate the issue, some drivers have resorted to taping over the rear camera, which is neither safe nor user-friendly. While I recognize Tesla has made improvements such as camera obstruction warnings (e.g., in FSD v12.5.6+), these do not address the core misclassification problem. My requests: That Tesla officially acknowledge and investigate FSD misbehavior in the presence of rear-mounted bike racks. That Tesla provide clear driver guidance on whether FSD should be used when such a rack is installed. That the FSD system include an option for a “Bike Rack Mode” or alternative logic to prevent rear-camera misinterpretation. That this concern be escalated within your safety and AI development teams to ensure user safety is prioritized.

I am writing to formally report a safety concern involving the Cybex Calisto G 360 convertible car seat. The issue pertains to a persistent rattling noise that emanates from the seat, specifically from the area near the child’s footrest, just above the belt tensioner lock mechanism. This sound occurs consistently during vehicle operation, regardless of whether a child is seated or the seat is unoccupied. I contacted the manufacturer, and their response was as follows: “After our Product Team reviewed your claim, it was determined that the amount of rattle you hear is completely normal. It passes our quality review for sound. The specific sound that is heard is from the metal rod inside the belt tensioner door.” While I appreciate their response, I remain deeply concerned. A rattling sound originating from a critical restraint mechanism area warrants a thorough safety inspection. The explanation that it is “normal” does not ease concerns about potential long-term reliability, wear, or failure of a restraint system component. Given that this noise may indicate looseness or internal movement of a part involved in child restraint tensioning, I strongly believe this issue requires further investigation by independent safety professionals. Please let me know if any additional documentation, photos, or videos would help in assessing the issue.

The lower control arm of the passenger front wheel separated from the vehicle entirely while the vehicle was in motion. There are two bolts which attach the bushing to the front sub-frame assembly. These bolts pass through the frame and are secured into nuts which are affixed to the frame. The bolts are not captured; there is no retention device (pins, wiring) which prevent these bolts from backing out of position, other than torque. Blue thread-lock compound was visible on both bolts, which remained present in the bushing after the control arm separated from the frame. When the arm detached from the frame, it dropped to the asphalt and made a loud grinding noise. The passenger side front wheel became directionally unstable and rotated inward and left, out of alignment with the intact driver-side wheel. This misalignment, while the vehicle was in motion, disrupted steering control and forced the passenger front wheel into the fender, causing friction and significant further damage to the frame and the suspension. This damage, combined with the driver's actions, stopped the car immediately. Fortunately, this occurred at low speed. Unfortunately, the cumulative damage left the vehicle immobilized in the middle of public road. Due to the great weight of the vehicle and the unstable front wheel, the vehicle could not be removed from the roadway and thus blocked traffic for several hours. The bolts, frame, and control arm were not visibly damaged. The bolts lost torque and backed out of the frame without noticeable indication that they were doing so. Tesla's characterization of the fault was that the vehicle "ejected" the bolts. Tesla repaired the damage under warranty.

While driving, a persistent error appears on the screen with a chime: "Front left safety restraint system issue" (Error Code: RCM2_a128). After researching online, it appears this is a commonly reported issue among Tesla owners and may have serious safety implications. The error code RCM2_a128 indicates a fault in the vehicle’s safety restraint system, specifically related to the seat belt or restraint mechanism on the front left side.

The primary safety restraint system, specifically the driver's side airbag, failed to deploy during a significant frontal impact collision. This severely compromised my personal safety, as my head struck the steering wheel with force, leading to injury and pain. Had the impact been more severe, the lack of airbag deployment could have led to much more serious, potentially life-threatening, injuries. Immediately after the impact, the primary braking system also malfunctioned, and the vehicle's warning and autopilot systems became compromised, posing further safety risks. The specific airbag non-deployment problem has not yet been reproduced or formally confirmed by a dealer or independent service center, vehicle is currently scheduled for its first post-accident inspection at a Tesla Collision Center address 6010 Richmond Ave, Houston TX 77057 on June 11, 2025, and is available for inspection. To date, the vehicle has not been formally inspected by the manufacturer, police, or insurance representatives for these specific malfunctions. Police responded to the accident scene and filed a report, but no technical inspection was conducted by them. There were NO prior warning lamps, messages, or symptoms indicating a malfunction with the airbag system before the collision. However, immediately after the collision, the primary brakes failed and the warning system and autopilot system showed signs of malfunction/disruption; no specific warning lights related to these post-impact issues appeared prior to their malfunction.

A suspension rod/bolt fell off my car. When I was making a right hand turn my car began screeching and shaking, I lost control for a second and almost hit another vehicle, luckily I was able to stop my car. I had my car towed to a Tesla service station for repair.

Description of Incident: I was taking my family on a road trip from Disneyland back home to Chandler, Arizona when our 2022 Tesla Model Y displayed a battery issue. We stopped in Palm Springs to charge, but the battery would only charge very slowly and capped out at 32%. We brought the vehicle to the Palm Springs Tesla Service Center, where they diagnosed a failure in the high-voltage (HV) battery and stated it would need to be replaced — a process that would take about a week. Given that the car is only two years old, I found it concerning that a battery expected to last around 10 years would already need replacement. We were provided a loaner vehicle and returned to Arizona. When the repair was completed, I drove the loaner vehicle back to Palm Springs (a 5-hour trip) to pick up my car. On the return drive home, I stopped at a Tesla Supercharger in Quartzsite, Arizona, but the vehicle would not charge. After spending over 90 minutes on the phone with Tesla roadside assistance, a tow truck was dispatched and took both me and the car to the Glendale, AZ Tesla Service Center. There, I was informed — again — that the HV battery needed to be replaced. I explained that this component had just been replaced two days ago in Palm Springs, and asked for an explanation. I was not provided with any specific technical reason for the repeated failure, other than being told that the battery "just needs to be replaced again." Safety Concerns: At this point, I am deeply concerned that there may be a more significant or systemic issue with the vehicle’s electrical or battery systems that has not been properly identified. The repeated HV battery failures — combined with the lack of a clear explanation — raise serious safety concerns for my family and me, especially given how reliant the vehicle is on this system for power, propulsion, and emergency response.
