ELECTRICAL SYSTEM
While on my way to run an errand, I opened up the back door to strap my 2 year old in, when i closed the door, the car would not open whatsoever, after trying for a few minutes with the phone key app for tesla and the physical key fob, nothing would work. I had to end up calling 911 and firefighters came out and had to physically open the door, which broke the window. The car was completely unresponsive and would not turn on. After researching what happened, it turns out the 12v battery had died. I was able to jumpstart the car with jumpers and that was able to open up the rest of the car's doors. However, during the time my son was stuck inside with the over 95 degree weather, the had no safety mechanism in place to open it physically like a traditional key fob would. It is very disheartening knowing my son could have potentially lost his life over something so simple that could be resolved with a physical keyhole on the outside like almost every traditional vehicle has. This is something that should not occur, ever. The fact that the car was able to open up once more before completely dying and perfectly at the wrong time after closing the door while my son was trapped in there in complete heat was very disappointing.

UNKNOWN OR OTHER
I own a 2021 Tesla Model Y with approximately 46,500 miles. The vehicle is currently displaying battery error code BMS_a079, and the battery will only charge to approximately 30%, which severely limits the driving range and makes the vehicle unreliable for normal use. I reported this issue to Tesla on March 6, but the earliest service appointment available to me is March 17 at the Tesla service center in Fayetteville, Georgia. Because Tesla service centers are not widely available, I must travel to another city to have the vehicle inspected. The limited battery charge creates a difficult situation because I must determine how to get the vehicle safely to the service center with very restricted range. I may have to arrange towing or attempt to drive a vehicle that cannot fully charge. This issue has also created a hardship for my household. I have a toddler and normal daily responsibilities, including errands and transportation needs, but the vehicle cannot reliably be used due to the charging limitation. Being without dependable transportation for an extended period of time places families like mine in a very difficult position. This problem appears to be related to the vehicle’s battery management system and is not the result of driver misuse. Consumers should not be placed in situations where a major battery fault leaves them with limited transportation options while waiting extended periods for service, especially when service centers are not easily accessible.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, LANE DEPARTURE: ASSIST, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The vehicle's Autopilot/Full Self-Driving (HW3) computer has failed at approximately 70,000 miles. Tesla Service has diagnosed the vehicle as requiring replacement of the HW3 computer. As a result of this failure, multiple safety related systems are inoperative, including collision avoidance, lane assist, lane departure warning, automatic wipers, and other driver assistance features including adaptive cruise control. The vehicle is also unable to receive over-the-air software updates, including potential safety updates. In addition, the vehicle experiences system lag, including delay when shifting into Drive or Reverse. The center display is slow to respond, and certain media and software features are no longer functional due to inability to update. This condition increases safety risk because active safety systems designed to assist with collision prevention are disabled. The failure appears to be hardware-related and not due to normal wear. Tesla has confirmed the need for computer replacement but has declined coverage as the vehicle is outside warranty. The failed component should be available for inspection upon request.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Vehicle will suddenly apply brakes while using standard cruise control for no apparent reason. This is extremely dangerous as it has almost caused several accidents on the highway. I have almost been rear-ended several times. This is a very common problem and well documented problem referred to as "phantom braking" on Teslas and something needs to be done immediately.

STEERING, LANE DEPARTURE: WARNING, LANE DEPARTURE: ASSIST
The car suddenly reduced lane assistance and steering assistance functionality. After calling Tesla they said it is not a software issue. I checked the service mode and it indicated a malfunction in the steering assist motor, which apparently costs $3500 to replace. Online, I have found many complaints about this problem that are not resolved by software updates. In addition, there was a large number used steering assist motors for sale online which indicates a more wide spread problem. This is not normal for cars to have this failure prematurely and is a serious safety hazard. I read online that some had their steering EPAS get locked while driving on the highway and nearly destroyed their Teslas

SUSPENSION
Vehicle experienced front suspension lateral link failure. The links separated from the sub-frame due to improperly secured fasteners. This is the exact defect described in existing recall SB-21-31-003 / NHTSA Campaign 21V835000. The existing recall states 'front suspension lateral link fasteners may loosen, allowing the lateral link to separate from the sub-frame.' This vehicle has this identical manufacturing defect but was not included in the recall database. Tesla Service confirmed the links 'fell out' and separated from the sub-frame at approximately 65,000 miles. Technician notes indicate a 'speed mismatch between wheel and motor' caused by the link separation - this is the symptom of the underlying fastener defect. The failure resulted in loss of steering control and made the vehicle undriveable (VOR - Vehicle Off Road). This is a safety-critical manufacturing defect affecting front suspension, creating crash risk due to sudden loss of vehicle stability and control. Owner is being charged for repair of a known manufacturing defect that should have been covered under the existing recall. This suggests the recall scope was too narrow and did not capture all affected vehicles with this defect. Request investigation into whether recall should be expanded to include additional affected vehicles.

STEERING
Received a notice that steering assist may be reduced. Other model year Ys have been recalled due to the same issue. It doesn’t make sense that this should fail in a vehicle that is 5 years old with no accidents and low mileage. This is a safety issue due to manufacturing defect and should be covered under warranty.

ELECTRICAL SYSTEM, STRUCTURE:BODY
On [XXX], after placing my young child in my Tesla and closing the door, the 12V battery failed suddenly and the vehicle became inaccessible. I was unable to unlock or enter the car. I did not receive any warning or alert that the 12V battery was about to fail. The vehicle was in my garage, and the window automatically cracked, which allowed me to monitor my child while I sought help. I called Tesla Roadside Assistance at 8:59 AM. During the call, the representative reassured me that help was being dispatched and at times described the service provider as “on the way” (timing details such as “within ~45 minutes” and the length of the initial call are my best estimates). After continued waiting with my child confined inside the vehicle, I contacted emergency services due to the safety risk. I called 911 at 10:03 AM. I later had the 12V battery replaced at my own expense. This incident involved a sudden electrical failure without warning that resulted in a child being trapped inside a disabled vehicle, and I am also concerned about the accuracy and effectiveness of roadside assistance dispatch communications during the incident.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When driving with cruise control engaged the car randomly brakes and shows a "curvature assist " indication. The car quickly slows from 55 to 35 with no warning. This primary happens on a straight road, not a curve. I am concerned about the traffic behind me.

After charging the vehicle threw error code “BMS_a079 Unable to charge - Maximum charge level reached Reduced maximum charge level - Schedule service”. The car would no longer charge and had to be taken in for service. Tesla advised the High Voltage battery needed to be replaced. Replacing the High Voltage battery resolved the issue.

UNKNOWN OR OTHER, ENGINE, ELECTRICAL SYSTEM
I parked my Tesla vehicle in a friend’s driveway. When I returned and opened the driver’s door, I entered the vehicle and attempted to put it into Drive. At that point, the vehicle display went completely blank and the vehicle became inoperable. I then attempted to open the door from inside the vehicle, but the door would not open and I was unable to exit the car. I was effectively locked inside the vehicle. I contacted Tesla customer support and remained on the call for approximately 1.5 hours before receiving assistance. Tesla customer support confirmed that the issue was caused by failure of the 12-volt battery. At the time of the incident, the outside temperature was below 0 degrees centigrade. The incident occurred in Cedar Rapids, Iowa. There was no prior warning or notification from the vehicle or the Tesla mobile app indicating that the 12-volt battery was at risk of failure. The failure resulted in loss of vehicle function and inability to exit the vehicle, creating a serious safety concern.

VISIBILITY/WIPER, UNKNOWN OR OTHER, LANE DEPARTURE: BLIND SPOT DETECTION
I noticed the windshield washer nozzle on the passenger side isn't either working or not there. I reached out to Tesla, and also stopped by a Local Dealership and they told me that it would cost me out of pocket, since it's out of warranty. Secondly, the left side driver repeater camera has a Glare when turned at night time only. which is quite dangerous due to very less visibility due to the Glare of the Turn signal light that causes the repeater camera to function properly. this is a on going known problem. I have reached out to Tesla for this matter. and I was advised that it would not be covered since it's not under warranty. This issue should be a recall that Tesla should fix. this isn't an issue caused by normal wear and tear it's a manufacturer defect.

STEERING
On Monday 12/29/2025, while driving my 2021 Tesla Model Y on the highway at approximately 70 mph returning from DTW Airport to my home with my children in the vehicle, the steering suddenly locked / the steering wheel would not turn. I was able to pull over to the shoulder. There were no warning lamps or warning messages displayed before or during the failure. After pulling over, I powered the vehicle off and back on. The steering partially worked again, and I was able to drive home. Later the same day at my friend’s house/driveway, the steering locked out again and this time it was completely locked, making the vehicle not safely drivable. Again, there were no warning messages or symptoms prior to the lockout. Tesla Service provided a written estimate documenting the complaint “steering locked out / cannot drive” and proposed replacing the steering gear/steering rack (“Steering Gear LHD,” part number 1188832-00-B) plus alignment, total about $3,127.70, at 96,042 miles. The vehicle and component are available for inspection upon request (Tesla can retain the replaced part). This is a safety defect concern because sudden loss of steering control on a highway without warning could lead to a crash, especially with passengers/children in the vehicle.
