2025 Tesla Model Y driver assistance problems

Filed Nov 8, 2026 · Driver assistance, Steering · CA

I own a 2025 Tesla Model Y, currently running software version 2026.38.5.12 with Full Self-Driving (Supervised) v14.3.13. On multiple occasions while using FSD (Supervised), the vehicle has made sudden, abrupt lane changes out of the carpool (HOV) lane with little warning. This has happened repeatedly on [XXX] and [XXX] in the [XXX] area, most recently on XXX. The system initiates these exits late and aggressively, steering toward the double yellow lines that separate the HOV lane from regular traffic, and I have had to grab the wheel and take control to avoid an unsafe and illegal maneuver. I am concerned the vehicle could cross the double yellow lines into fast-moving traffic, or exit the HOV lane at a non-designated opening, creating a serious risk of collision. A driver should not have to fight the car to keep it from breaking traffic law. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Subject: Multiple Recurring Issues — 2025 Tesla Model Y Long Range AWD I am submitting this complaint regarding multiple quality and potential safety-related issues with my 2025 Tesla Model Y Long Range Dual Motor AWD, purchased new in January 2025. 1. Persistent HVAC moldy/musty odor The vehicle develops a pronounced moldy or musty odor from the HVAC system, particularly in hot, humid, or rainy conditions. This raises concerns about possible moisture accumulation, microbial growth, or an underlying HVAC system defect. I have attempted to resolve this issue through Tesla service, including communications with the Randolph and Princeton service centers. I have experienced repeated scheduling difficulties and have not received a clear diagnosis or satisfactory resolution. I also investigated Tesla technical service information concerning HVAC inlet ductwork, including bulletin SB-26-18-002, but have not obtained a satisfactory determination regarding the applicable components on my vehicle. 2. Windshield residue affecting the front camera area I have also experienced an issue involving residue or plastic off-gassing contamination on the windshield in the area of the forward-facing camera system. This raises concerns about visibility through the camera's viewing area and the potential impact on camera-based driver-assistance functions. I have sought clarification regarding cleaning and inspection of this area. I would like this issue evaluated to determine whether the contamination is associated with an underlying vehicle material or manufacturing problem and whether it could interfere with the proper operation of safety-related camera systems. 3. Rear hatch seal and wind noise The vehicle also has a rear hatch area wind-noise issue that may be related to the hatch seal or its fitment. I am concerned about whether the seal is properly installed and functioning as intended. I would like the issue evaluated to determine whether it reflects a component, alignment

On XXX, I was driving my 2025 Tesla Model Y with Full Self-Driving (Supervised) engaged. While merging onto [XXX] in [XXX], the vehicle veered and crashed into the guardrail. I was not controlling the vehicle at the time — FSD (Supervised) was in control. Both of my child passengers were injured; one suffered a wrist fracture. A police report was filed at the scene. The vehicle was totaled in the crash and has not been driven since. Vehicle software at the time of the crash: 2025.45.9.1; Full Self-Driving (Supervised) v14.2.2.4. After the crash, I asked Tesla for the vehicle's driving data/logs to confirm that FSD was engaged at the time of the crash. Tesla did not provide the data. I am concerned that Full Self-Driving (Supervised) failed to safely execute a highway merge maneuver and drove the vehicle into the guardrail, resulting in injuries to my children.

On [XXX], at about [XXX], I was driving my 2025 Tesla Model Y with Full Self-Driving (Supervised) engaged. I was on [XXX] in Matthews, NC, heading toward Mint Hill, at about [XXX]. There were no vehicles, pedestrians or obstacles ahead of me. With no apparent reason and no warning or alert, the vehicle suddenly braked as hard as possible. It slowed from about 49 mph to 32 mph within roughly one second, which averages about 0.8 g. I took over from FSD and submitted feedback to Tesla marking the event as critical. It was nighttime and the weather was clear. Fortunately no vehicle was behind me, but if one had been, a rear-end collision would have been likely. The car was running software 2026.27.11 with FSD (Supervised) v14.3.10. I have dashcam footage of the event.

When self parking in a drive way, Tesla Y hit another car. There was more than enough space on the driveway for 2+ cars. We did the same self-parking tens times before. Tesla generated no alarms after collision. It didn’t stop after colliding with another car. I brought the Tesla to Irvine Tesla dealer and requested that the dealer checke cameras and software. The agents refused. They only checked if the car still self parks. The claimed as no alarms were generated during collision, they are not going to check cameras or anything else. The gave me no paperwork at all. I believe it’s a serious precedent that may affect thousands of Tesla owners and compromises their safety.

The vehicle has suffered recurring, critical electronic and low-voltage safety system failures that first began under the original factory warranty and have now resulted in a complete central computer (HW4) failure. History of Defect: 1. Feb 2025 (~7,170 miles): Initial failure of the 16V low-voltage network and safety systems. Tesla replaced the VCFRONT body controller and low-voltage battery under warranty. 2. May 2025 (~14,543 miles): Safety equipment failures required replacement of the cabin radar and seat belt buckles under warranty. 3. Sept 2026 (~80,000 miles): Total Hardware 4 (HW4) central computer failure. This resulted in the complete loss of all Active Safety Systems, Forward Collision Warning, Automatic Emergency Braking, Autopilot, backup cameras, and power management features. Safety Risk: The complete failure of the HW4 computer completely disables essential safety functions required for safe vehicle operation on public highways. Tesla has denied warranty coverage for the HW4 replacement despite the issue originating from early low-voltage controller failures during the bumper-to-bumper warranty period. ADDITIONAL CRITICAL SAFETY INCIDENT: During the computer/system failure, I experienced a power steering malfunction accompanied by an on-screen warning. The steering wheel became extremely hard to turn/stiff, making it nearly impossible to steer the vehicle safely.

On I95 by the Secaucus Train station there is something sending a signal to my Tesla and other Teslas to disable all of its ADAS systems. All of the functionality related to ADAS gets disabled thus making the car very unsafe to drive. Due to this disability it also disables the camera systems in the car. So if an accident were to occur there would be no way to record.
