2023 TESLA MODEL Y Complaints

Purchased used 2023 Tesla Model Y from Tesla on April 17, 2026 at ~16,300 miles. Pre-delivery, Tesla notified me by text that the vehicle failed state safety inspection due to front upper ball joint play (a known Tesla Model 3/Y defect). Tesla repaired it at its own service center and certified it as passing on April 8, 2026. No warning lamps or messages. ~12 days post-delivery a family member reported a noise from the left rear; the vehicle was then parked. On May 10, 2026, I removed the left rear wheel and found the left rear brake caliper completely detached from the rear knuckle. Both caliper bracket mounting bolts were missing. The caliper was held only because it had seized on the rotor. Vehicle unsafe to operate. Towed by flatbed to Tesla May 11; available for inspection on request. Properly torqued caliper bracket bolts do not back themselves out in ~800 miles of light use. Realistic causes: (a) bolts installed but not torqued to spec, worked loose in service; (b) bolts missing at state inspection and certified anyway; (c) suspension disassembled during the pre-sale repair, bracket reassembled with bolts omitted. All implicate Tesla's workmanship; (b) and a visibly-loose (a) also implicate the inspection. Tesla previously acknowledged this failure mode in recall SB-21-33-002 ("Loose Brake Caliper Bolts," 2019-2021 Model 3 / 2020-2021 Model Y): caliper bolts "may not be torqued to internal specifications" and "may be loose, allowing the brake caliper to separate." My vehicle is outside that range but the recall shows this is a known Tesla pattern. Risk: caliper detachment can wedge the wheel, lock the brake, damage tire/wheel, boil brake fluid, or break free at speed — any can cause loss of control. Vehicle driven ~800 miles in this condition. Dealer confirmation pending; Tesla instructed in writing not to repair pre-inspection. State Police ASED complaint filed; formal dispute filed with Tesla Resolutions.

While reversing my Tesla Model Y, the rear parking sensors failed to alert me to a stationary obstacle (fence). No audible warning or visual alert was triggered. The vehicle had recently received a software update prior to the incident. The failure resulted in collision damage to the rear bumper. I believe this may be a sensor or software defect. I am requesting an investigation into whether recent OTA updates affected rear obstacle detection functionality.

On May 8, 2026 at approximately 1:15 PM in [XXX] , my 2023 Tesla Model Y unexpectedly locked with my [XXX] infant inside during approximately 100°F weather. I briefly exited the vehicle while charging to disconnect the charging cable. My authenticated phone key remained inside the cabin. Immediately after unplugging the charger, the vehicle activated Walk-Away Door Lock and locked all doors despite the phone key remaining inside the vehicle. I was locked out without access to my phone and had to ask a stranger to call 911 and contact my husband. Cabin temperatures rapidly became dangerous for an infant. My husband was eventually able to remotely unlock the vehicle using the Tesla app, narrowly avoiding forced entry by emergency responders. The vehicle failed to detect the phone key inside the cabin and improperly initiated locking while a vulnerable child occupant was present. This created a serious risk of heat injury or death. The vehicle also failed to prevent the lockout despite an infant occupant being seated in the second row, raising concerns about whether rear-seat occupancy detection and child safety protections functioned properly during the event. I am requesting investigation into Tesla’s proximity sensing, phone key detection, walk-away lock behavior, and child occupant safety protections during charging/unplugging events.

I was driving in Topanga Canyon, heard a loud clang. Noticed the steering was off, so pulled over. The front lateral links had failed and it took me 6 hours to get a tow. Had I been at freeway speeds when that happened, I may have crashed and not been able to pull over safely as I was headed towards the 101 freeway before the links failed. Upon researching this, I found online this is a common issue with Tesla’s. If I need it don’t again, I don’t want to have to pay for an issue that’s a manufacturers defect.

Recurring camera and Autopilot defect on a 2023 Tesla Model Y (HW3 with in-cabin camera, in scope for NHTSA Recall 23V838). 7 service visits in 13.5 months and ~14,000 miles of my ownership. Tesla verified the camera/Autopilot defect in writing on 12/5/2025 and replaced the upper Quad Camera Cover (P/N 1755687-00-B) and Interior Camera (P/N 1588124-S0-I). Same defect returned by 4/27/2026. On 4/28/2026 Tesla service issued a Could Not Duplicate citing 'no log data showing signs of autosteer having an issue or any camera blocked alerts.' But Tesla's own VIN-linked telemetry, which Tesla provided me via Privacy Portal data request, contains: 28 Autopilot FAULT events on 14 of 27 retained days; 1 ABORTING event matching my report to the minute; and 17 highway-speed (>=50 mph) phantom-brake-class hard decelerations <= -0.20 g. The worst event: 4/28/2026 at 2:12 PM EDT, less than 90 minutes after Tesla returned the vehicle. Autopilot was in ACTIVE_NOMINAL state with cruise engaged at 63.6 mph. System produced an unprompted -0.252 g (-2.47 m/s^2) deceleration. Driver was not braking; system was driving. Additional phantom brakes: -0.297 g at 62.9 mph on 5/2/2026; -0.294 g at 70.0 mph on 5/3/2026. Multiple Take Over Immediately alerts without explanation. Camera Blocked alerts in clear conditions. Driver-monitoring system flagged 'hands NOT detected' on 339 of 684 monitoring detection events during the 27-day window despite hands being on the wheel — the recall remedy mechanism is failing on this vehicle. This vehicle is in scope for NHTSA Recall Query RQ24009 (open), investigating whether the 23V838 OTA remedy actually fixed the underlying Autosteer defect. My data is direct fleet-level evidence the remedy did not work on this VIN. Currently in active New Vehicle Limited Warranty.

While using Full Self-Driving on my 2023 Tesla Model Y, the automatic high beams repeatedly activate in active traffic conditions, including when following other vehicles and when oncoming traffic is present. The system does not consistently dim the lights, creating glare that could impair visibility for other drivers. The driver is unable to permanently disable automatic high beams while FSD is engaged.

Safety Defect Complaint – Tesla Model Y FSD v14.2.2.5 I am reporting unsafe speed behavior in Tesla Model Y Full Self-Driving (FSD) software v14.2.2.5. FSD uses selectable driving profiles (Sloth, Chill, Standard, Hurry, Mad Max) to control speed, but provides no definition of how these profiles affect speed or limits. Tesla also removed the ability to manually adjust speed incrementally, reducing driver control. While in Standard mode, the vehicle exceeded the speed limit by 12 mph, resulting in a photo radar citation. This was not driver-initiated. I have experienced at least six incidents where the vehicle exceeded the speed limit by 10+ mph without warning. Two design issues create significant safety risk: The right scroll wheel now controls both microphone and FSD profile selection. Its multi-directional design allows unintended inputs that can change speed profiles (e.g., to Hurry or Mad Max) without driver awareness. There is no audible or visual alert when this occurs. The vehicle can accelerate beyond safe/legal speeds before the driver realizes and disengages FSD. The driver-set speed warning (set to 8 mph over limit) failed to activate during multiple overspeed events, including the citation incident, despite being enabled. This removes a critical safety safeguard. Speed increases have occurred both gradually and rapidly, reducing reaction time. Safety Risk: unintended acceleration, loss of predictable speed control, lack of driver alerts, and failure of safety warnings. These conditions could lead to violations or collisions. I request NHTSA investigate whether this constitutes a safety defect.

While driving on I-95 North in the fast lane at highway speed, my 2023 Tesla Model Y experienced a sudden loss of propulsion and displayed a warning indicating the vehicle was shutting down. The vehicle rapidly decelerated and would not respond to acceleration or drive engagement. Steering remained functional, which allowed me to maneuver the vehicle across lanes to the shoulder to avoid a potential collision. This required an emergency maneuver in active highway traffic with my family in the vehicle. A soft reset did not resolve the issue. After performing a hard reset, I was able to move the vehicle slowly off the roadway to a nearby location where it was later towed. This incident occurred without prior warning and created a significant safety hazard due to sudden loss of propulsion at highway speed.

Washer fluid indicated low washer fluid. Refilled washer fluid, but shortly after washer fluid leaked out underneath the vehicle. Took the vehicle in for repair at an Tesla Service Center and service advisor indicated that the reservoir had cracked at the seam (an obvious defect of the reservoir). They stated it was not considered a defect even though it was obvious the crack was at the seam. Given the age of the vehicle and the fact that the vehicle is constantly garaged when parked this seems to be an abnormal issue. Had I not taken this in to get serviced there could have been an issue with not having any washer fluid in the reservoir when needing to clean the windshield which would pose a visibility hazard and could potentially lead to a collision.

### Summary: Sudden Unintended Acceleration (SUA) from a stationary position. ### Vehicle Configuration: 2023 Tesla Model Y Long Range AWD. Battery Type: NMC. ### Incident Details: On April 19, 2026, at approximately 10:00 a.m., the vehicle was stationary on a flat surface at 6722 Vista Del Mar Ave, San Diego. I was in the driver's seat with the vehicle "On" but stopped, conversing with two witnesses. My feet were completely clear of both the accelerator and brake pedals. ### The Event: Without driver input, the vehicle suddenly and forcefully accelerated forward. I immediately slammed the service brake with full force. The vehicle traveled approximately 20 feet before the brakes brought the car to a halt. ### Evidence & Gaps: Two eyewitnesses confirmed the vehicle moved autonomously without pedal interaction. A manufacturer data report was requested, but it showed a specific data gap for the exact seconds of the acceleration event, despite providing second-by-second logs for the rest of the day.
