2026 Tesla Model Y problems

EXTERIOR LIGHTING

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

FORWARD COLLISION AVOIDANCE: WARNINGS

On September 11, 2026 at 5:11:51 PM in San Jose, CA, FSD (Supervised) had been engaged continuously for 23 minutes. The vehicle was traveling straight in its lane at 32 mph and still accelerating. FSD disengaged with no takeover warning: no visual alert, no chime. My data export from the manufacturer (200 ms resolution) confirms the timestamp and shows the driver-monitoring channel never entered either of its warning states during the drive, though both appear elsewhere in my data. Nothing I did caused it. Steering torque stayed within sensor noise, with no rightward torque at any point. First brake application was 5.56 seconds after; first accelerator input 15.5 seconds after; no steering wheel button events near the event. Immediately afterward the steering angle moved about 7 degrees right over five seconds with my torque still near zero. The vehicle left its lane toward parked cars and came very close to striking them. No forward collision warning, no automatic emergency braking. I braked manually and stopped. I re-engaged FSD 36 seconds later and again two minutes later. Both times it steered right again and I disengaged. No warning lamps or messages appeared before any of this. The manufacturer reviewed logs remotely but has not inspected the vehicle or reproduced the problem. They attribute it to reduced forward camera visibility. My export shows one camera-related alert for that drive, logged 23 minutes earlier and absent from the incident window. They later stated the vehicle logged 30 non-customer-facing "low" obstruction events over two weeks, and that a customer alert appears only for significant obstruction. I drove extensively in that period without incident. A condition judged not worth notifying me about should not also explain withdrawal of steering control at 32 mph. Root cause is unconfirmed pending a paid diagnosis I have not authorized. Vehicle available for inspection. I have dashcam footage and the full export.

When I manually disengage Tesla FSD while the vehicle is moving, a persistent feedback popup appears. It cannot simply be dismissed and requires interaction or feedback to clear. This has happened every day since FSD 14.3.2 was released, including September 13, 2026, the incident date entered on this form. This creates visual and cognitive distraction at the exact moment I have assumed manual control and need to focus on driving. I sometimes disengage FSD simply because I want to drive; disengagement does not necessarily indicate an FSD failure. Feedback should be optional, readily dismissible, or deferred until the vehicle is parked. I request that NHTSA review this behavior as a potential driver-distraction safety issue.

SEAT BELTS

Hello, I am requesting assistance with an unresolved noise issue coming from the rear seat belt area of my Tesla. I have been experiencing this noise for quite some time. I brought the vehicle to a Tesla Service Center in April, and at that time, the advisor advised me that they did not yet have a solution for the issue. I was told that because the concern involved the seat belt area, they needed to be careful with the repair and that I would be contacted once a proper solution was identified. I never received that follow-up. I am now being told that the noise is “normal,” which is unacceptable. This is a brand-new vehicle, and I paid a significant amount of money for it. I should not have to accept an ongoing noise that appears to be related to a manufacturing or assembly issue, especially after I was previously told that the concern was not normal and that Tesla would work toward a repair. I am requesting that this matter be formally escalated to management and reviewed again. I would like: A documented case number Review by a Service Manager or Regional Tesla representative Another inspection and road test of the vehicle The rear seat belt noise documented clearly on the repair order A clear explanation of the repair plan or next steps Please assist me in getting this issue resolved as soon as possible. I would appreciate a prompt response and confirmation of who will be handling the escalation. Thank you.

Vehicle: 2026 Tesla Model Y System involved: Full Self-Driving (Supervised) Date of incident: September 2, 2026 Approximate time: 5:20 PM Location: I-10 area near Tucson, Arizona Crash: No Injury: No Near-miss / safety-critical event: Yes I am reporting a serious safety incident involving the Full Self-Driving (Supervised) system in my 2026 Tesla Model Y. On September 2, 2026, at approximately 5:20 PM near Tucson, Arizona, I was using Full Self-Driving (Supervised) while traveling toward I-10. The vehicle was expected to enter I-10 but did not enter the highway as intended. Instead, the vehicle proceeded onto a service road, then entered an abandoned parking lot. Rather than safely correcting the route it started towards highway ramp against the normal direction of traffic. I immediately took manual control,stopped in an empty emergency area between the ramp and the service road and activated my emergency hazard lights. I remained stopped while approaching traffic slowed after observing my vehicle. Once it was safe to proceed, I manually and slowly repositioned the vehicle in the correct direction and entered I-10 using the ramp. There was no collision and no injury. However, I believe this event created a serious and potentially fatal risk because the vehicle’s automated driving system directed the vehicle toward a highway ramp in the wrong direction, creating the possibility of a wrong-way conflict with incoming traffic. I am also notifying Tesla for evaluation. I wonder if more similar incidents were reported recently (I learned the fatal collision killing passenger on Oct 31st in AZ due to FSD malfunction).

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

Whenever I disengage full self driving the car forces me to tell it why I did it via an on screen selection. It does not go away after a period of time. I used to be able to dismiss it by hitting the voice button twice but they've removed that loop hole. It's very distracting and forces me to interact with the screen while driving. The selection screen also blocks the blind spot cameras. It comes up even when disengaging to park. Someone is going to wreck messing around with this forced distraction.

EXTERIOR LIGHTING

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.

ELECTRICAL SYSTEM:ADAS:AUTONOMOUS/SELF DRIVING

The contact owns a 2026 Tesla Model Y. The contact stated that while the vehicle was in Full Self-Driving (FSD) Mode, while reversing into a parking space, the vehicle initially stopped while approaching a pillar on the driver's side; however, the vehicle then proceeded to park and scraped the driver’s side of the vehicle against the pillar. The contact was concerned about the vehicle failing to stop while approaching an object. The contact stated that the failure might have been reported to the manufacturer through the steering wheel voice recorder. The failure mileage was approximately 10,000.

I recently purchased this vehicle. I love it. It has a trial of full self driving, which I love almost all of the time. However, I noticed there is not any of the 5 settings for FSD that do not speed in school zones. I want to use FSD as much as possible, but I will not speed in a school zone. I am amazed that Tesla has been allowed to program the FSD in a way that will allow speeding in a school zone. I have to turn off FSD to maintain safety and avoid a ticket. Please require TESLA to have at least one of the 5 settings that will obey school zone speed limits.

LANE DEPARTURE: BLIND SPOT DETECTION

On approximately August 15th,2026, I experienced a serious near miss while driving my 2026 Tesla Model Y at approximately 70 mph on an interstate. I activated my turn signal and began moving toward another lane while another vehicle was in or approaching my blind spot. I did not receive an audible blind spot warning early enough to alert me before beginning the lane change. The audible warning occurred only after I was already moving toward the occupied lane and the situation had become dangerous. My previous vehicle, a 2015 Hyundai Santa Fe, provided an audible warning when the turn signal was activated and another vehicle was detected in or near the blind spot. That earlier warning gave an opportunity to cancel a lane change before a dangerous situation developed. I believe the Tesla Model Y should provide an optional early audible blind spot warning when the turn signal is activated and another vehicle is detected in or rapidly approaching the blind spot. This would supplement the visual warnings and could help prevent high-speed lane-change collisions without requiring the driver to look toward a display. I respectfully request that NHTSA evaluate whether the timing and design of audible blind spot warnings in the Tesla Model Y provide drivers with adequate advance warning and whether an earlier audible alert could improve safety and save lives.
