2021 TESLA MODEL Y- Lithia, FL
Component that failed: Front lower lateral link and compliance link suspension bushings. Failed components were removed by Tesla Service and are no longer available for inspection. Safety risk: Failed suspension bushings directly compromise steering precision, vehicle stability, and handling — particularly at highway speeds. A driver unaware of this failure could experience loss of steering control or unpredictable handling without warning. Confirmed by dealer: Yes. Tesla Florida (Tampa, 11945 North Florida Avenue) confirmed the failure in writing on May 22, 2026. Technician repair notes state: “inspection failed due to worn suspension bushings in the front.” Tesla confirmed this was the first time these original components had ever been serviced. Invoice #[XXX]. Manufacturer inspection: Yes, repaired by Tesla Service Center. Cost: $1,669.58. Warning lamps or prior symptoms: None. No warning lights, no alerts through the Tesla app, and no prior symptoms communicated to the owner. Failure was discovered only because vehicle was brought in for an extended service agreement inspection. Assessment: Original factory suspension bushings completely disintegrated at 56,258 miles on a 2021 Tesla Model Y (VIN: [XXX] ). This is not normal wear — photographic evidence shows full structural disintegration of rubber bushing material. Other Model Y owners may be driving with identical failures without knowledge.

2021 TESLA MODEL Y- Pearland, TX
I am reporting two unresolved safety-related defects on my 2021 Tesla Model Y (VIN: [XXX] ) that occurred following paid service at Tesla's League City Service Center on 04/16/2026 DEFECT 1 — COMPUTER AND SENSOR SYSTEM FAILURE: The vehicle's onboard computer cuts in and out intermittently. Sensors fail during operation and the problem worsens significantly in high-temperature conditions. Tesla vehicles rely on their computer and sensor systems for core safety functions including collision avoidance, autopilot, and driver assist features. Intermittent failure of these systems while operating the vehicle is a safety hazard to the driver and the public. DEFECT 2 — GLOVE BOX INOPERABLE: The glove box does not open following Tesla service. The glove box in Tesla vehicles houses key vehicle documentation and is integrated into the vehicle's locking and security system. I paid $2,497.50 for service on [06/16/2026]. Both defects were either caused or left unresolved by that service. I have notified Tesla service staff directly and followed up multiple times over more than four weeks. Tesla has not responded, has not scheduled any repair, and has not refunded my money. I am filing this complaint because (1) the sensor and computer failures present an active safety risk during operation, (2) Tesla has ignored all attempts to resolve this, and (3) public reviews indicate this is a pattern affecting multiple consumers. I request that NHTSA investigate and determine whether a safety defect investigation or recall is warranted. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2021 TESLA MODEL Y- Manor, TX
The vehicle’s low-voltage battery system failed unexpectedly, causing a complete loss of electrical power and preventing normal vehicle access and operation. The failure resulted in my [XXX] child becoming trapped inside the vehicle. The malfunction appears related to the 12V/low-voltage battery and/or associated power management system. The vehicles inspection invoice is available upon request. This incident created a serious safety risk because the loss of low-voltage power prevented normal door operation and immediate access to my child. The situation posed risks of heat exposure, medical distress, panic, and delayed emergency access. Although the vehicle includes a manual emergency door release, it is not realistically accessible or operable by a baby or toddler secured in a child safety seat. A young child cannot reasonably be expected to understand, locate, or operate the manual release during an emergency. The sudden failure without warning left my child unable to exit independently while caregivers were temporarily unable to access the vehicle. There were no noticeable warning, messages, or other symptoms prior to the failure. The low-voltage battery appeared to fail suddenly and without sufficient warning, resulting in immediate loss of access and vehicle functionality. The problem has not yet been reproduced, but the low-voltage battery failure was identified after the incident. The vehicle has been inspected by Tesla service. No formal police or insurance inspection was performed, but a first responder was present. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2021 TESLA MODEL Y- San Ramon, CA
My 2021 Tesla Model Y HW3 experienced complete failure of all cameras, GPS, Automatic Emergency Braking, and Adaptive Cruise Control following the installation of software update 2026.8.6.1 — the OTA remedy update issued by Tesla for NHTSA Recall 26V283000. The vehicle was fully functional prior to this update. The failure was confirmed and reproduced by Tesla's authorized service center. The service advisor confirmed in writing: "During the update, the computer failed to reboot properly. We attempted to perform a 12V reset but unfortunately it is still stuck in the boot loop state." The Autopilot ECU (Primary/Turbo A) is stuck in a permanent boot loop and cannot be recovered by software means. Safety impact: All cameras including rearview camera are completely non-functional. Automatic Emergency Braking and all ADAS features are disabled. The vehicle cannot safely detect obstacles or pedestrians. GPS navigation is frozen. Tesla has confirmed the computer requires replacement but is classifying it as a customer-pay repair citing expired warranty, despite the failure occurring during Tesla's own recall remedy software deployment. This vehicle meets every technical criterion of Recall 26V283000 — HW3 hardware, 2021 Model Y, software version 2026.8.6.1, complete camera failure — but does not appear in the recall VIN database. I am requesting NHTSA review whether this VIN should be included in recall 26V283000 or a related investigation.

2021 TESLA MODEL Y- Big Rapids, MI
The vehicle began experiencing repeated Autopilot/FSD failures while driving. Symptoms included sudden Autopilot disengagements, cruise control becoming unavailable, and loss of road visualization/navigation display functionality. The issue progressively worsened over time. The vehicle was first brought to Tesla service in 2025 for the same overheating-related concern. At that time, Tesla identified a coolant-related issue, topped off the coolant system, and returned the vehicle to service. However, the problem continued and gradually became more frequent and severe afterward. During the most recent service visit, Tesla diagnosed the HW3 Autopilot computer as overheating due to a heat transfer failure between the Autopilot board and cooling cold plate. Tesla stated that heat generated by the board could no longer be efficiently transferred to the coolant system, causing the Autopilot computer to overheat. Tesla further advised that continued operation without repair could eventually impact additional vehicle functions, including the center display screen shutting off due to overheating-related failures. Given the loss of driver-assistance functionality and potential impact to core vehicle systems, I am submitting this report so the issue is documented as a potential thermal management or hardware reliability concern involving the HW3 Autopilot computer system.

2021 TESLA MODEL Y- Bridgeview, IL
My 2021 Model Y has about 24,500 miles began squeaking when turning the steering wheel or hitting bumps. I read online that many tesla owners had the same issue. The design on these weren't great allowing water to penetrate these parts and cause them to ware down faster. I already paid for the replacement of the upper and lower control arms.

2021 TESLA MODEL Y- Port Huron, MI
while traveling at approximately 80 mph with Full Self-Driving (Supervised) engaged, my vehicle experienced a simultaneous failure of the Full Self-Driving computer and the Media Control Unit (MCU) touchscreen. Without any prior warning, the touchscreen went completely black, and the vehicle immediately executed an uncommanded, sharp steering maneuver into the right lane. It was very apparent that if I didn’t take over it was going to continue crossing highway lanes and go off road. I have around 45k miles specifically on FSD and never has it failed in such an extreme manner. This sudden steering input put myself and other motorists at extreme risk of a high-speed collision or roadway departure. I was forced to physically overpower the steering wheel to maintain lane integrity and prevent a crash at highway speeds. The failure appeared to be a total loss of the vehicle’s primary visualization and automated steering systems, leaving me with no digital feedback regarding speed or surrounding traffic while the car was still in motion. Prior to this event, there were no warning lamps or symptoms such as GPS drifting or screen lag. I have since attempted a hard reset and a full power cycle, but the critical nature of this uncommanded steering at 80 mph suggests a systemic defect in how FSD manages hardware or software failures. The vehicle and its internal data logs are available for inspection upon request. This incident has been documented in the Tesla App under a service request for a full log review.
