2021 TESLA MODEL Y

I was entering the on-ramp to [XXX] , from [XXX] , to merge onto the freeway east bound towards [XXX] , when my Tesla suddenly lost all power, the brakes did not work and the power steering completely failed making it feel like it was locked up. I was traveling approximately 40-50 mph at the time nearing the gore point to merge onto the freeway. Fortunately I was in the inside lane and I rolled to a stop away from other vehicles. I could not steer at all. Had I been completely on the freeway, I could have been rear ended badly. I had my two young boys in the vehicle with me, both [XXX] and [XXX] . We were completely trapped in the vehicle with no power. My [XXX] old remembered to use the manual latch to get out. I opened my door manually and It broke my driver side glass window. Vehicles were passing us rapidly to enter the freeway. I called my husband who is a police officer and he came and picked us up. We called Tesla who said they could not get a read on our battery whatsoever. We called a tow company and had this vehicle towed to Tesla repair center in [XXX] , after reporting our traumatic event. They claim our warranty is expired, but our vehicle only has 37,638 miles and should be covered under the 8 year, 120,000 mile warranty that covers a major malfunction like this.

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.

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.

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.

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.

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

front subframe and both front lateral links came loose due to welded nut not present

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.

The upper control arm bolt came loose on its own.

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.

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.

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.

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.

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.

Both front half shafts failed and had to be replaced by Tesla. I did research and this part is known to be substandard, was recalled in China, and remains a problem in the US.

The contact owns a 2021 Tesla Model Y. The contact stated that while the vehicle was parked, the contact observed the code BMSA079 on the computer, and messages "Vehicle Unable to Charge to Maximum Charge Level" and “Maximum Charge Level Reached - Reduced Maximum Charge Levels" were displayed. The vehicle was taken to a dealer, and it was determined that one coil in the battery was inoperative, and the dealer reduced the charge and refused to increase the battery charging level. The manufacturer was notified of the failure. The failure mileage was 155,000.

The vehicle’s high-voltage battery and charging system experienced repeated failures, preventing charging while the vehicle was parked. This issue occurred three times: January 2024: Charging error “BMS_a079. Unable to charge” appeared. Vehicle was stranded and required service intervention. Mileage ~28,125. November 2024: Same charging error during winter travel, vehicle stranded mid-trip, creating safety risk for passengers. Mileage ~38,744. September 2025: Charging error recurred mid-trip, vehicle had to be left at a service location. Mileage ~48,918. All incidents were reported to Tesla under battery warranty. Repairs were attempted each time, but the problem recurred. A repurchase request was submitted after the third incident and was denied, with only a goodwill service credit offered. Safety concerns include the risk of being stranded, particularly during long trips or in winter conditions, which could affect passengers and other road users. The battery and charging system were inspected by Tesla service personnel after each incident, and the failure was confirmed each time.

In May 2025, Tesla pushed an over-the-air (OTA) software update overnight while the vehicle was parked. When the vehicle was started the following morning, the update had failed mid-process and stalled at approximately 50%. Immediately upon startup, the backup camera and navigation/maps stopped functioning. The vehicle has been unable to complete subsequent software updates since. Tesla service later inspected the vehicle and indicated that the main computer/ECU was stuck in a loop and required replacement. The backup camera and navigation loss occurred immediately following the OTA update and persisted for several months despite multiple service attempts. Due to the vehicle’s rear design and limited rear window visibility, operating the vehicle in reverse without a functioning backup camera significantly impairs visibility. Even when using mirrors or physically turning to look backward, rearward visibility is restricted. As a result, the loss of backup camera functionality presents an ongoing, daily safety hazard during normal vehicle operation.

In early Nov 2025 my Tesla Model Y began intermittently showing warnings about the forward collision warning system and multiple sensors being offline. Tesla service replaced a faulty connector on Nov 3. On Nov 15, 2025, about two weeks later, the car had a sudden drivetrain failure while I was parking on a steep hill. I heard a loud bang from the front of the car and the vehicle immediately lost drive power and had to be towed. Tesla diagnosed a failed front motor inverter that blew the high-voltage pyrofuse and damaged the 12V battery; they replaced those parts. The vehicle is available for inspection and the repaired components and records are with Tesla. After that repair the car needed another visit for alignment and has continued to show worrying behavior: “VCFRONT offline/unable to contact VCFRONT” in the service menu, repeated “autopilot computer overheating” messages, intermittent loss or reduction of regenerative braking (braking feel changes unpredictably), a rear right seatbelt malfunction warning (later inspected and cleared by Tesla), and what appears to be significantly increased battery drain compared to before the inverter failure. This has now resulted in four service visits within about a month, all at Tesla service centers (no police, insurance, or independent shops involved). Tesla has confirmed the inverter/pyrofuse/12V failure and says the overheating was due to an air pocket in the cooling system, but the VCFRONT messages, inconsistent regen braking, and increased drain have not been fully resolved or clearly explained. I am concerned that a sudden loss of power, loss of regen, or failure of VCFRONT/autopilot systems could recur at speed or in traffic, creating a serious safety risk. Please note that I'm only able to view partially-complete paperwork from the latest service appointment in the Tesla app. I have requested this documentation from Tesla and will be able to provide all the service reports and communication as a follow-up.

Tesla diagnosed a failed front motor inverter that blew the high-voltage pyrofuse and damaged the 12V battery; they replaced those parts. The vehicle is available for inspection and the repaired components and records are with Tesla. After that repair the car needed another visit for alignment and has continued to show worrying behavior: “VCFRONT offline/unable to contact VCFRONT” in the service menu, repeated “autopilot computer overheating” messages, intermittent loss or reduction of regenerative braking (braking feel changes unpredictably), a rear right seatbelt malfunction warning (later inspected and cleared by Tesla), and what appears to be significantly increased battery drain compared to before the inverter failure. This has now resulted in four service visits within about a month, all at Tesla service centers (no police, insurance, or independent shops involved). Tesla has confirmed the inverter/pyrofuse/12V failure and says the overheating was due to an air pocket in the cooling system, but the VCFRONT messages, inconsistent regen braking, and increased drain have not been fully resolved or clearly explained. I am concerned that a sudden loss of power, loss of regen, or failure of VCFRONT/autopilot systems could recur at speed or in traffic, creating a serious safety risk. Please note that I'm only able to view partially-complete paperwork from the latest service appointment in the Tesla app. I have requested this documentation from Tesla and will be able to provide all the service reports and communication as a follow-up.
