Blind Spot Detection Problems of Tesla Model Y - part 1

There are two major safety issues that came with the vehicle upon the new car delivery. The problems existed even before the delivery as I found the first issue during the new car delivery and the second issue upon leaving the delivery center. First is the non-operational fsd (full self driving). Fsd never worked from the beginning. The Tesla advisor noticed it at the delivery center but insisted that it will work after 10 minutes of driving, needing calibration. However, after more than several hours of driving and 35 miles of driving, fsd still doesn't work and the display says fsd is non-functional. Second is the lane departure and lane approach sensor. When the neighboring car approaches from the side, there is no alert or notification. The blind spot sensor doesn't work either. This is a big safety issue and I almost got into an accident had I looked back and noticed a car approching from behind when I tried to move into the right lane. I expalined both of these two major issues with the vehicle and left the car at the service center in vienna, va, expecting the repair to be done within hours as promised. However, the service technician later sent a message via Tesla app that the part is missing from the car and the part needs to be ordered. It's been a full day and Tesla is still in the process of finding the issue, which means they still don't know what the issue is. I belive this is not the quality of product and testing that has been registered with Tesla in NHTSA. This surely represents the sub-par quality product and lack of full testing that needs to be done prior to the new car delivery. The service center employee responded via app that the car needs to in repair for 5 full days and may need more time if necessary. This is definitely not the quality and experience that are advertised by Tesla.

Tesla's full self-driving software continues to malfunction. On January 30th at 9:50 a. M. Mountain standard time I was parked at work and discovered my vehicle was left unlocked with a partial window unrolled. This was my first indicator of many faulty problems signaling the vehicle was not operating properly. The vehicle has a proximity sensor via bluetooth that locks and unlocks the vehicle on the owners approach was not properly working. On January 31st I experience a catastrophic failure with the software of the vehicle as I was locked out of my vehicle after utilizing summons feature that stopped the vehicle in the middle of the intersection obstructing traffic. Police arrived on scene within 30 minutes and we were unable to put the car in any gear to either drive the vehicle or place it in neutral to roll it out of the way. I have detailed video of the incident which is a better accounting of the incident on both occasions, the 30th and 31st of January. This is roughly the third or fourth occasion of Tesla's system producing a catastrophic failure resulting in damage to the vehicle or property damage.

On January 20, around 9:35 am, phoenix time, I had the car in self-driving mode for a left-hand turn at the intercession of camino real and river road in tucson, arizona. A real-time view shows that it’s a tricky and dangerous left-hand turn. For the past 3 weeks, the car navigated it well, waiting until it was perfectly safe to do so. Today, however, the car moved quickly and unexpectedly into the center of river road, narrowly escaping a head on collision with a west-bound car, and then paused, squeezed in between west and east-bound lanes when I tapped the brake and took the wheel. Everything happened so quickly. I made the left turn into the east-bound lane, but, looking back, I don’t know how an accident didn’t occur, as traffic was still moving in east-bound lanes rapidly. There must have been enough distance between two cars at just the right time, that nothing hit me.

All safety and most computer related features in the vehicle have failed. Cruise control, backup cameras, all other cameras, the navigation (assuming this is also impacting the projection of remaining battery life as my car always thinks it is at my home), warning signals for approaching obstacles/dangers, cruise control of any kind does now work, lane departure warning has failed, and automatic windshield wipers do not work. This happened without warning and was not related to an update. On January 13, 2026, the car worked in the morning and then all of these issues started happening. I made a Tesla service appointment, but they are not able to see me until February 3, 2026.

The computer in my car has been undergoing short circuiting, rendering all driver safety features inoperable. This is a known problem with hardware 4 and reported many places. I was backing out of my garage and the read camera and automated braking are not functional and it is nearly impossible to see out the back. When backing out, I struck another car in the driveway, resulting in damage to both cars. Had the system been functional, visibility would have been there and the automated braking would have avoided the collision. The vehicle has been seen by Tesla and I have been told that the warranty has expired and the computer must be replaced at my cost. Tesla has replaced other computers under a recall for the same issue reported. This is a serious safety issue as without a functional computer, features such as software updates, navigation, bilnd spot monitoring, lane keeping, cruise control, all cameras (rear, side, front), autopilot, autobraking etc. Are nonfunctional.

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.

The Tesla computer freezes. Sudden there is no information from the car, no miles per hour, no navigation, no side view cameras. I can drive the car but that's is all. Since the navigation is entirely dependent on the computer I can't tell where I am going. It has happened more than 30+ times in the car.

All cameras went blank on vehicle 4 year and 7 months old. All driver assistance systems became suddenly disabled. Tesla service diagnosis established that computer needs to be replaced for a cost of $2,000.

Statement of facts regarding Tesla accident [xxx] on [xxx], I was involved in an accident with a Tesla that I had rented directly from Tesla’s rental program. The vehicle was equipped with Tesla’s full software capabilities, including autodrive and the Smart summon feature. At no time during the rental process was I given warnings, training, or any overview about how these features work, the risks they pose, or the long history of reported incidents involving Teslas colliding with stationary objects while operating under self-driving or summoning functions. On [xxx], I used the summon feature for the first time in the parking lot of my business at [xxx] . The car was parked in spot [xxx], where I regularly park. I attempted to use summon while standing in full view of the vehicle, but the software repeatedly displayed “lost connection. ” after disabling WI-fi, I held the summon button again and the car successfully pulled out of the spot, drove forward, and arrived directly in front of me. This demonstrated the feature was functioning properly on that day. On [xxx], while again parked in the same spot, I attempted to demonstrate summon to my wife. I was standing in clear view, approximately 50–75 feet away, near the complex entrance. As before, the software repeatedly displayed “lost connection. ” I attempted to reengage by hitting the summon button to reconnect the command. That did not work. When I walked up to the vehicle, I discovered that the front quarter panel near the wheel had come into contact with the covered parking pole. At no time was I aware that the car had hit anything, nor did the system provide any alert that it had engaged with an object. This stands in stark contrast to the way Tesla’s software consistently warns when the car is being manually driven — giving constant alerts when drifting out of a lane or approaching another vehicle. The absence of such a warning during summon demonstrates a failure of the software’s sa information redacted pursuant to the freedom of information act (foia), 5.

While attempting to park my Tesla, I accidentally struck another vehicle’s side step with the front passenger side of my car. The other vehicle was not damaged, but my Tesla sustained visible damage. The vehicle’s camera system failed to detect or display the side step, giving the impression that there was sufficient clearance. As a result, I relied on what I believed to be accurate visual guidance from the Tesla camera system. During a follow-up visit to the Tesla service center in gilroy, California, I was told that similar incidents have occurred before. According to the technicians, the camera system has known limitations in detecting low-profile or side-mounted obstacles, such as running boards or side steps. This presents a significant safety concern. Tesla vehicles rely heavily on cameras and sensors for driver awareness, particularly during parking maneuvers. When key blind spots exist in the system—especially in areas the driver may not be able to visually confirm easily—it puts both property and people at risk. Drivers are conditioned to trust the vehicle’s spatial guidance systems, but in this case, that trust may lead to preventable accidents. Given Tesla’s growing market share and the increasing use of its camera-based safety and autonomy features, I believe this issue could affect many other drivers. It may warrant broader review to determine whether a design or software update is necessary to improve detection of low-profile obstacles and better inform drivers in parking scenarios.

The Tesla “self driving” features are inconsistent, at best, and frequently fail. I can not believe that the government approves these capabilities or the Tesla is accepting liability for road use. If these features are not reliable under supervised conditions, why would they be considered safe for robo taxi release? I have repeatedly tried to report this to Tesla and they say the systems are operating as designed.

The primary safety restraint system, specifically the driver's side airbag, failed to deploy during a significant frontal impact collision. This severely compromised my personal safety, as my head struck the steering wheel with force, leading to injury and pain. Had the impact been more severe, the lack of airbag deployment could have led to much more serious, potentially life-threatening, injuries. Immediately after the impact, the primary braking system also malfunctioned, and the vehicle's warning and autopilot systems became compromised, posing further safety risks. The specific airbag non-deployment problem has not yet been reproduced or formally confirmed by a dealer or independent service center, vehicle is currently scheduled for its first post-accident inspection at a Tesla collision center address 6010 richmond Ave, houston TX 77057 on June 11, 2025, and is available for inspection. To date, the vehicle has not been formally inspected by the manufacturer, police, or insurance representatives for these specific malfunctions. Police responded to the accident scene and filed a report, but no technical inspection was conducted by them. There were no prior warning lamps, messages, or symptoms indicating a malfunction with the airbag system before the collision. However, immediately after the collision, the primary brakes failed and the warning system and autopilot system showed signs of malfunction/disruption; no specific warning lights related to these post-impact issues appeared prior to their malfunction.

I am writing to formally raise a complaint regarding a serious malfunction that occurred in my Tesla Model Y (2024) following a recent software update pushed by Tesla. A couple of days ago, my vehicle received a new over-the-air software update. After installation, my car began displaying two error messages, and key safety features, including detection of nearby vehicles and warning systems, ceased functioning. This creates a significant safety risk when driving, as the car no longer alerts me to surrounding traffic or visualizes other vehicles on screen. Upon contacting Tesla customer service, I was instructed to schedule a service appointment, which I did for may 21, 2025, at 2:15 pm. During the appointment, the Tesla service advisor confirmed that the issue began only after the software update. However, I was told I would need to pay $3,000 out-of-pocket to repair the issue because my car is no longer under warranty. I raised the point that the malfunction was caused directly by Tesla’s software update. Despite this, I was informed that Tesla refuses to repair it at their cost, even after acknowledging the connection between the update and the malfunction. Moreover, the technician informed me that this issue could escalate and create safety hazards in 4–6 months, yet no resolution or recall has been offered. Given the acknowledgment that: the problem was introduced by Tesla's software, the malfunction affects critical safety systems, and there is imminent risk to safety, I believe Tesla should bear responsibility for the repair and ensure the vehicle is safe to operate. This situation warrants urgent attention, both from a consumer protection and vehicle safety standpoint. I request that Tesla take full accountability and cover the repair costs immediately, or offer a rollback/fix to the software that caused the issue. Otherwise, I will be escalating this matter to the national highway traffic safety administration (NHTSA) and consumer protection agencie.

Shortly after purchasing the vehicle in late 2024, I began experiencing multiple safety-related malfunctions. These issues include: full self-driving (fsd) malfunction: on the third use of fsd, the vehicle attempted to enter a left-turn lane but failed to fully move into the lane, resulting in the right front panel of the vehicle colliding with the bumper of a truck in the adjacent lane. There were no warnings from the system prior to the collision. The incident occurred at low speed. The truck sustained no visible damage, and the rubber from the truck's bumper transferred to the car, which was removed by hand later. This event raised serious concerns about the safety and reliability of the fsd system. No police report was filed, and the manufacturer was not present at the scene. Backup alert system failure: on several occasions while reversing, the car failed to issue audible or visual alerts despite vehicles being within 10–15 feet. In one instance, the screen finally showed a red zone when a car was within 10 feet, but still provided no audible warning. This issue has been intermittently reproducible but not consistent. It poses a significant risk to pedestrians and other drivers, particularly in low-visibility or driveway situations. Manufacturer's response: the vehicle was inspected by Tesla. After one in-person service visit and extended discussions, Tesla service representatives stated there was “nothing more they could do” and that a buyback was the only next step. A buyback request was submitted by a Tesla representative but has not been acknowledged or resolved more than 45 days later.

- computer appears to stop working in colder temperatures (or random). - all cameras, including rear view camera (needed for backing up) and side cameras stop working. Error message shown on touch screen saying cameras are not available. - all road sensing information including other cars, lanes markers (everything) disappears from touch screen dashboard and no longer works. There are no longer any warnings for anything. - gps tracking stops and no longer tracks along with the car. Car becomes a safety hazard due to poor visibility. Especially evident during reverse.

On 2/15/2025, while backing out of a driveway at about 7:30pm, the vehicle backed into a parked car directly behind it parked in street. There was no warning signal emitted that an object was behind the car. There was no safety alert on the display. Essentially the vehicle's sensors did not see the vehicle directly behind it.

This report addresses concerns regarding recent safety updates in the Tesla Model Y, specifically focusing on the "rear cross traffic alert" and the blind spot warning system. These updates are intended to enhance driver awareness and prevent collisions. However, there are significant shortcomings in their current implementation that may compromise driver safety. 1. Rear cross traffic alert: intended functionality: the "rear cross traffic alert" is designed to warn drivers of approaching vehicles from the side when reversing, thereby preventing potential collisions. Current implementation: the system currently highlights a portion of the infotainment screen in red when a potential hazard is detected. There is no accompanying audible alert to notify the driver of the danger. Safety concerns: drivers are likely to be looking over their shoulder or at their mirrors while reversing, rather than at the infotainment screen. The lack of an audible alert means that drivers may not notice the visual warning, especially if their attention is directed away from the screen. This could lead to an increased risk of collision, as the visual cue alone may not be sufficient to capture the driver's attention. 2. Blind spot warning system: intended functionality: the blind spot warning system is designed to alert drivers of vehicles in their blind spot when the turn signal is activated, helping to prevent lane-change collisions. Current implementation: similar to the rear cross traffic alert, the system highlights the screen in red when a vehicle is detected in the blind spot. No audible warning is provided to alert the driver. Safety concerns: in adverse weather conditions, such as rain, drivers may rely more heavily on blind spot warnings due to reduced visibility. Drivers typically turn their heads to check for vehicles, which means they may not see the screen's visual alert. Without an audible warning, drivers may inadvertently change lanes into an occupied space, increas.

The rear view camera didn't work, neither did the windshield wiper. When turning left or right, the sensors did not display anything, the display no longer displayed any distances to other cars, proximity lines, nor speed limits. Gps also did not work. The problems were confirmed by the dealer (and fixed), but they charged us even though the incident involved a software update on their part that made most advanced safety features unavailable available. When we tried to reverse, we could not see anything. When we tried to make a left or right turn, there were no sensors available to sense blind spots. When we tried to understand the speed limit or change lanes, the information was not available. Wipers were patchy in use auto pilot also did not work. Warnings kept beeping while driving, but we could not turn it off, serving as a distraction to driver, but Tesla was unable to address the repair due to their mass recall of other cars (with similar issues).

Software update applied ota. Complete failure of ecu on reboot, including cameras, rear backup camera, all proximity warnings, cruise control, fsd, gps, navigation, battery preheating, etc. Car is unsafe to drive in this state.

The car lost all adas functions, and gps on the onboard navigation system. In addition. It can't use regular cruise control and it does not have rear view mirror blind spot warning capability any more. This all happened when the car attempted to install the "holiday" updated from Tesla automatically around 11/29/24 .

All cameras and related functions stopped working, including back up camera. Gps is not working. Tesla pushed back my service appointment until 1/21/25. Safety is an issue now due to blindspots and they will not give me a loaner car. Tesla informed me the computer needs to be replaced. They reported this is wide spread and Tesla is not sure why it happened. I was informed that even though my new appointment is 1/21 it is likely that it would be pushed back further. I have only had this car for 5 weeks. No warning lights came on prior to this happening.

Vehicle information: • make: Tesla • model: Model Y • year: 2024 description of the problem: after a software update pushed by Tesla, the ap4 computer in my 2024 Tesla Model Y shorted out, causing a complete failure of all systems controlled by this computer. The following safety-critical and driver-assist features have become non-functional: cruise control (adaptive or otherwise) back up camera forward collision warning lane departure warning lane keeping assistance blind spot warning parking collision warning full self-driving and auto park features cameras required for autopilot functionality additionally, because the gps system has failed, the vehicle’s navigation system is inoperable. This impacts Tesla’s unique route planning feature that sets up supercharger stops during long journeys.

I initially visited the milford, CT Tesla service department and communicated through the Tesla ap on 12/14/2024 regarding my 2024 Tesla Model Y, which has only 2,357 miles on it. The car's cameras, sensors, & navigation stopped working, making driving unsafe. Now, the bright lights do not go on. The vehicle's camera/sensors are critical for safe operation. Tesla said the car may need a new computer, but they have none in stock. They texted me that they have many people facing the same issues.

Hello , I just bought the new Tesla Model Y 2024 in the October and all of a sudden all the driver assistance programs are not working, including the rear camera(reverse camera) I took it for the service on December 4th and they fixed issue on December 5th. After few days on December 13th the same issue happened again and Tesla service center is saying I need to wait till February 20th 2025 for the repair. All cameras are not working in the car, it does not show any backup camera, no forward collision warnings or no lane change assist Tesla is not considering this as a safety issue I am including a chat summary with the service center via pdf file. I have included previous repair invoice also when the same issue happened on 4th December.

On 12/13/24 after a software update my rear , front and side cameras stopped working. This includes blind spot cameras, and side turn signals. In addition the side mirrors are tiny because the car was designed to use cameras. The back window also has very low visibility. Tesla has confirmed that the car needs a new computer for all cameras and software navigation. The replacement computers are on back order and have scheduled a service replacement in six weeks time. In the meantime, they refuse to provide a loaner car. This car is brand new with only two months worth of usage. They say the car is drive able, but without the main safety cameras I don’t feel safe, the aesthetic of the car was designed to have working cameras. It is very hard to use the tiny side view mirrors and look out the tilted rear window. This is a commuter car, driving over 90 miles on highway per day. I am concerned for safety issues.

Tesla has told me the ap4 computer has failed in my car which has resulted in them having to replace it. I had this issue start right around thanksgiving. I scheduled the soonest appointment available at 12/24 however Tesla contacted me and moved my appointment because they stated that the part was unavailable at this time and should be delivered by 01/20/25. Not offering me a rental or anything on my brand new '24 Tesla. It has just over 4000 miles on it and is ~2 months old now. This issue impacts: emergency braking, blind spot detection, lane keep/centering, assisting with parking, automatic high beams and wipers, cruise control/ adaptive cruise control, vehicles built in gps to be stuck at one location every time, has made my touchscreen not automatically brighten or dim, my auto dimming mirrors be too dim in most driving conditions, constantly fail to install system improvements and safety updates, and because my vehicle keeps trying to do this, it has caused increased battery drain as well. This has increased the safety risk of my vehicle tremendously. . . Tesla has not seemed to publicly acknowledge the issue yet either.

All of the cameras on the vehicle are no longer working after the latest update. This means all sensors (even as simple as windshield wipers) do not work. All driver safety assistance does not work.

The automatic pilot computer (ap4) failed on my 2025 Tesla Model Y after approximately 400 miles. This controls a lot of the vehicle's auto pilot features but it also controls a lot of its safety features, such as the back-up camera, forward collision warning and blind spot warning. As of 19 December, the Tesla service center has had my vehicle for 14 days with no fix for the foreseeable future.

They advertise it as a computer failure. The cruise control doesn't work, none of the cameras displays, causing me to hit the lawnmower in my garage. Other functions as navigation, range prediction, and automatic light/dark display switching don't work either.

Starting on 12/4/2024, my car's camera stopped working, no blind spot warning, no navigation, no rear view camera and no cruise control. Reported to Tesla on 12/8 and they said it is a known problem nationwide and some autopilot computers are getting shut or something. They have given me an appointment for 1/4/2025. The vehicle is really unsafe to drive without these components working and the vehicle draws on heavy amount of battery usage without these controls and for my commute on highway, I am always nervous about if there is going to be enough for me to reach the next charging station. I would expect this falls into safety recall and Tesla should at least send out a service bulletin as well as provide alternate vehicles for the owners to use until this can be fixed.
