Owner reports
Selected complaints filed with NHTSA by 2026 Tesla Model Y owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2026 Tesla Model Y. The contact stated that while the vehicle was in the Standard Mode or in Cruise Mode, depressing the brake pedal, there was a delay with the brake lights illuminating. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the taillights were functioning properly. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 3,000.
FSD was unable to avoid object in road, may be due to how the adaptive headlights work as I was unable to see the object as well FSD/adaptive headlights may may it hard or impossible to see objects on road at night No In the process of a insurance claim No
The front trunk (frunk) on my 2026 Tesla Model Y Juniper lacks both internal lighting and an emergency safety release mechanism. This design flaw creates an unnecessary and severe safety risk, as a small adult or child could easily become trapped in the frunk with no way to signal for help or escape. In low-light conditions-such as at night or in a garage without adequate illumination-the absence of a light would exacerbate disorientation and panic for anyone trapped. Without an internal release latch or glow-in-the-dark handle (standard in many vehicle trunks to prevent entrapment deaths), this could lead to a life-threatening suffocation or injury situation, especially if the frunk is accidentally closed on a person during loading/unloading. …

Tesla Full Self-Driving (FSD) - control handover protocol. Vehicle is available for inspection upon request. WHAT HAPPENED: On June 25, 2026 at approximately 4:17 PM, the vehicle was operating under Full Self-Driving (FSD) navigating into a residential driveway. The driver pressed the gas pedal to take manual control. At the exact moment FSD transferred control, vehicle telemetry confirms the steering wheel was at 299 (nearly 3 full turns of hard left lock). No warning was given. With a ~13:1 steering ratio, approximately 300 of wheel rotation was required before driver input would affect the front wheels - taking 0.4-0.5 seconds during which the front wheels remained pointed left despite the driver turning right. The vehicle struck a tree at approximately 13-15 kph. …
My 2026 Tesla Model Y front trunk ("frunk"), an Austin, Mar 2026 build, lacks internal lighting & emergency release (unlike 2025 models; the change started Oct 2025). Frunk size/capacity remained unchanged, allowing child up to 4yo to fit & get trapped w/ no escape or signal, esp. in low light. Violates FMVSS 401 (https://www.ecfr.gov/current/title-49/subtitle-B/chapter-V/part-571/subpart-B/section-571.401) which states: "Each passenger car with a trunk compartment must have an automatic or manual release mechanism inside the trunk compartment that unlatches the trunk lid, if the trunk is large enough so that the three-year-old child dummy described in Subpart C of Part 572 can be placed inside the trunk compartment, and the trunk lid can be closed and latched". Request recall/retrofit & investigate Model Y frunk complaints. …
This is a proactive step to report that the headlights on Model Y Juniper 2026 are not projecting seamlessly onto the road. The low beam shows patchy lights and also has a blocked-out grey patch on the right-hand side of the car. This patch is not due to any wreckage of the headlights. The high beam is also not precise and feels as if it is a column of light, which is not very clear to drive in. I took my car to Tesla's dealership, and according to them, that is how the lights project, even on their demo car. I think the headlights should project a clear light onto the road, and these are not. This could cause an accident due to a lack of clarity.
The rear light bar is extremely unsafe, it is especially undercarriage lighting which is illegal to have on while the vehicle is in motion. Not visible enough during inclement weather conditions, and can cause glare issues for other drivers while the roads are wet, due to its downward shining. The light can easily be obscured by hauling things such as bike racks. People are wrapping the plastic panel u deer the light which can alter performance. The light does not illuminate the full width of the car giving drivers behind a false sense of the car's width. This has to be the most unsafe light on any car on the market
Water entusion in the tail light bar. After time causes corrosion of the circuit board on the turn rear turn signal making it inoperable. tesla doesn't have an open document nor a recall. Was quoted over $1300 to replace the assembly. I did a teardown of the root cause. Glue sealing the through hole for the clip that holds the badge of the car on the rear didn't adhere. Water entered the assembly and dripped onto the circuit board, over time corrosion occurred. My rear left turn signal went out on a car that just turned a year. I have documented the location of the fault with pictures
Ever since our 2026 Tesla Model Y was purchased in June 2026, we routinely receive a "Center Brake Light Condition Detected" error message. We have brought the vehicle in for service, and have been advised that the issue is not hardware-related and will be fixed through a "future software update". We have been waiting nearly 3 months for a remedy but Tesla Service has been unable to provide a status report on the remedy. A number of other Tesla owners have commented on Reddit that they have the same issue with their vehicles.
