Vehicle Speed Control Problems of Tesla Model 3 - part 1

The vehicle’s brakes did not work, automatic emergency brakes and collision warning both did not work. I pressed on the brake for about 5 seconds but the brakes did not work, resulting in a collision with the car in front. Everything is available for inspection if needed. Both my safety and the driver of the vehicle in front of me was at risk. The problem has not been confirmed yet. The vehicle is currently at a shop, waiting inspection. There were no warning lamps, messages, or symptoms.

In the new Tesla update to full self drive they removed the ability to adjust the speed control while using fsd yet state "note: you are responsible for the speed and control of your vehicle at all times, whether fsd (supervised) is enabled or not. ".

Full self drive 14. 1 removes the max speed setting that allows drivers to control the speed of the vehicle while under computer control, leaving no way to prevent the car from speeding when the speed profiles choose to drive over 28+ mph over the speed limit. The lack of ability to control the speed of the system is fundamentally unsafe by design.

The center display (vehicle pad) on my 2018 Tesla Model 3 went completely blank while driving. This eliminated access to all vital driving information including the speedometer, gear selection, and safety indicators. Safety concern: without visible speed data and wipers the vehicle cannot be operated safely or legally. I attempted to reboot the system and power cycle the vehicle but the screen still failed.

My family and I were in my Tesla Model 3 2022 and heading from charlotte to orlando on [xxx]. The car was in full self-drive (fsd) mode while commuting through daytona beach. The rain was heavy in the area. While driving in daytona beach, fsd caused the car to change lanes and go to a lane that had standing rain puddles on [xxx]. After fsd caused the lane change, the car immediately hydroplaned out of control. The car's short clearance from it's bottom and the ground which traps water that exacerbates hydroplaning, along with its generative breaking feature made matters worse and uncontrollable. The car spun into the median three times and settled in the middle of danger interstate. The car is totalled. My family and I require medical attention and counseling due to the trauma.

Repeatedly and randomly, with cruise control (not fsd) engaged, the car would brake, sometimes aggressively. The last time, it braked so hard the tires or brakes squealed and the car swerved slightly before I was able to regain control. This was on the freeway (in colorado, if I remember correctly) while I was cruising at 70 or 75 mph. I decided that that was the last time I would use cruise control; it was just not safe. I had an appointment on October 22 to take the car in for service. But then a friend told me this was called "phantom braking" and that there was no fix. A friend suggested that I contact the NHTSA.

I love my vehicle and its technology. However after installation of the latest (fsd v14) update, I observed issues I believe pose a risk to the safe operation of the vehicle. I have made dozens of reports for 30+ days to Tesla for these issues. 1. Driving profiles and speed the update features multiple driving profiles (e. G. , "sloth", "chill", "standard", and mad max). Only the "sloth" profile drives at the “speed limit” (what their outdated map thinks speed limit is). All other profiles drive over the posted speed limit (sometimes significantly). The ability to manually adjust the speed limit setting has been removed or disabled in these profiles. Once the vehicle is in a profile, the system stays in its own selected speed. This behavior prevents the driver from easily controlling the maximum speed when using the system, undermining driver-intent. 2. Incorrect or outdated speed limit data the vehicle frequently displays incorrect speed limits: for example, school zones, reduced speed zones, temporary speed changes, work zones, and even a busy high way I drive everyday that’s been changed for 3 months now, are often not recognized or updated in the system. On several occasions over the past months, the system continued to use an outdated or incorrect posted speed, despite the road clearly being a lower limit. Because the system uses the erroneous speed data as the basis for its automated driving decision (and without manual override of speed in fsd), this situation increases risk-especially in areas where lower speed limits are enforced for safety (pedestrian zones, near schools). 3. Safety risk description the lack of manual speed adjustment under autonomous mode means the driver has less control over vehicle speed when using fsd, reducing the driver's ability to mitigate risk in a dynamic environment. I’m asking for Tesla to either make sure they have constant real time speed limit data, or allow again for manual speed adjusts when in fsd.

The contact owned a 2023 Tesla Model 3. The contact stated that while driving at an undisclosed speed in the third floor of a parking garage, the vehicle suddenly accelerated to full speed unintendedly, and the steering wheel and the brake pedal were inoperable, causing the contact to lose control of the vehicle. The vehicle crashed into a wall and crashed into the vehicle in front, and the vehicle stopped. No further information was available. No warning lights were illuminated. The front driver's side air bag deployed. The vehicle was towed to a tow lot and was deemed a total loss by the insurance company. A police report was filed. There was no injury sustained. The manufacturer was not notified of the failure. The failure mileage was 66,000.

On September 18, 2025, my 2023 Tesla Model 3 (VIN: 5yj3e1eb9pf632327) suddenly accelerated on its own and the brakes failed to respond despite repeated pressing. To avoid hitting other vehicles, I turned into a property driveway and struck a tree. The airbags deployed. This was a case of sudden unintended acceleration combined with complete brake failure, creating a serious safety hazard. Forward collision warning also did not prevent the impact. A police report was filed by the dekalb county police department, GA, USA (report #25-074809, case #0440200), which specifically documented brake failure as the cause of the accident. The report also notes that the driver was injured by the airbag and that the vehicle had to be towed from the scene. A copy of the police report can be provided upon request.

Incident #1 vehicle sitting at a red light. After several seconds the vehicle operating under Tesla fsd suddenly started to drive as if the light had turned green, which it had not. I stopped it immediately. Incident #2 vehicle was stopped a t a red light and started forward again as it the light had changed but had not. I noticed a flashing red light at the next intersection a few hundred feet away. So, I went around the block and tried again and it behaved the same. After a few seconds it started to go again. There was not another light near where the first incident occurred.

On September 7, 2025 at ~7:53 pm, my 2025 Tesla Model 3 operating with full self-driving (fsd) engaged performed an aggressive, uncommanded turn while under computer control. The maneuver occurred so abruptly that I could not safely override steering before impact, and a crash resulted. The Tesla app trip view for trip 3 (7:34–7:53 pm) shows “vehicle on fsd” for 18 min 54 sec and records an “aggressive turning” event at 7:53 pm (2. 0 sec) immediately before the trip ended (screenshot attached). This reflects a steering/driver-assist control defect in fsd’s turning behavior and a failure of collision-mitigation to prevent the crash. I sustained bodily injuries and the vehicle incurred significant damage. I request that this incident be treated as a safety-critical malfunction warranting investigation and corrective action.

On [xxx], at just 9,526 miles, my brand-new 2025 Tesla Model 3 (VIN: [xxx] ) suffered a front motor/inverter failure. The vehicle displayed the warning “front motor disabled. ” Tesla vallejo service confirmed this and replaced the front drive inverter (3du). A catastrophic drivetrain failure at under 10,000 miles is unacceptable and raises serious concerns about reliability and safety. It still doesn't not accelerate as before. In addition, since delivery on [xxx], this vehicle has had persistent rattling and vibration issues in the cabin. I have returned to Tesla vallejo multiple times (April, June, July, and August 2025). Each time, the service manager, steve mcnerney, dismissed or minimized my concerns, blaming “seatbelt rattling” or claiming the issue could not be replicated. After July, I even sent three separate videos clearly documenting the noise, yet the most recent service invoice still instructed me to “provide a video,” showing Tesla ignored or failed to record my evidence. This ongoing defect has been reproduced and confirmed at Tesla service but remains unresolved. Tesla’s dismissive handling and failure to fix the defects create both safety risks and loss of confidence in the vehicle. A front motor failure while driving could result in loss of power, reduced acceleration, or unsafe driving conditions. Tesla has failed to provide a reliable or safe resolution despite repeated repair attempts and clear evidence. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I want to add an update to my previous report # 11690629. I think it would be helpful to provide what the max speed should be based on my input. So, I will just resubmit the previous report with some additional information. On December 31, 2024, I purchased a new Tesla Model 3 long range with full self-driving (fsd). The problem is the car goes faster than it should when full self-driving is activated. I have attached an example photo of the Tesla screen taken while the car is being controlled by fsd. It shows the actual speed limit of the road is 35 mph, and the car is traveling at a steady speed of 51 mph. It also shows a “max speed” of 64 mph which means the car may travel that fast on this road if it chooses to. Since I use an offset of 10%, the max speed in this 35 zone should be 39 mph. However, the car increased it to 64 mph, and I certainly did not use the right scroll wheel to increase it. This is clearly a safety issue which can lead to accidents. Tesla has made 5 attempts to fix this without success. On the last attempt (September 24, 2025), they refused to answer my questions such why does the max speed suddenly change to a value much higher than my specification? they simply stated that the system was operating as designed. Really? it’s design to drive 51 mph in a 35 mph zone? furthermore, they went on to say I should disengage the fsd system or intervene manually if I believe the car is operating in an unsafe manner. One reason I purchased this car was for fsd. I would expect them to fix it rather than my having to abandon this feature that I pay for. I hope you will encourage Tesla to fix this issue before there are any more fsd-related accidents.

Vehicle information: 2023 Tesla Model 3 VIN: [xxx] incident date: [xxx] location: [xxx] summary of the problem: on [xxx], while autopilot was active, my 2023 Tesla Model 3 suddenly accelerated without driver input. I was pressing the brake pedal, but the vehicle surged forward uncontrollably, struck a fence and a tree, and caused major property damage. Both I and my wife (passenger) required urgent care treatment after the crash. Details / safety defect evidence: •Tesla’s own raw logs show the accelerator spiked to 100% immediately before impact. •brake pressure was recorded prior to impact, proving the brake pedal was applied. •despite this, Tesla’s official vehicle data report falsely states “manual brake not applied. ” •autopilot did not disengage when the brake was pressed, contrary to Tesla’s design claims. •the vehicle logged a “near-deploy collision” at ~27 mph, yet the airbags did not deploy. Why this is a safety defect: this incident reflects multiple critical failures: 1. Sudden unintended acceleration. 2. Failure of brake-override safety design. 3. Airbag non-deployment in a crash severe enough to trigger “near-deploy. ” 4. Inaccurate Tesla reporting that conceals braking input. This defect created an extremely dangerous situation that could easily have resulted in fatalities. I am requesting NHTSA investigate Tesla vehicles for unintended acceleration, brake override failure, and airbag non-deployment.

On August 7th, 2025 at around 8 am in the morning, my vehicles mobile phone car key was in-operable and I was unable to get in the car which led me to trouble shoot how to fix this issue with the car. Upon researching I was directed by Tesla to directly complete a soft reset of the vehicle holding down both buttons on the vehicle once I was inside, and pushing on the brake pedal. Upon completion, my vehicle booted up and I realized that all camera systems were down, my navigation systems were down, my safety features were down, my auto pilot, lane keeping assist and auto brake were down, sensors were down and I was no longer able to pre heat my battery to charge my vehicle due to issues with the navigation. I then took the vehicle to Tesla service center irvine where a service advisor quoted me 2900 for a new ecu and bolts and told me that I needed to replace my whole unit and that I was to cover the cost of the repair even though my vehicle is only 2 years of age and this failure is due to the quality control and software of the vehicle. I have been driving around a vehicle with absolutely no safety features whatsoever such as no cameras, sensors, auto braking, or full self driving due to this ecu failure and I fear for my safety and well being while driving this car.

Had acc set on 80 mph on the hiway yesterday. A vehicle was passing me and the Tesla suddenly applied heavy brake pressure to the point of tires screeching. Speed dropped very quickly to about 50 mph. I had not touched the brake pedal. Brakes released and speed resumed to 80 mph. Very scary and high risk of rear end collision. Lucky nobody was behind me. Don’t want to experience that again.

While driving to work on a local road, I approached a red light where there were no vehicles immediately ahead. However, my vehicle unexpectedly steered off the road in front of a construction sign, entering a ditch. Despite my attempts to regain control of the steering and braking systems, I was unsuccessful. The vehicle subsequently stopped automatically on an incline. Fortunately, I avoided a collision with a gas station and intersecting roadway, but sustained damage to my car’s front bumper. Law enforcement and a towing service were contacted to remove the vehicle. I tried calling the dealership almost half day without an answer, then I went to the dealership where they told me that the hardware is fine but they can’t do anything about the possible software issues which leaves me in a situation where I’m nervous to drive the car. I reached out to the company about the accident and didn’t hear back yet from them. I request a thorough investigation into this incident to determine the cause of the unexpected, highly dangerous, autopilot behavior. I am disturbed mentally and emotionally due to the accident. I also require confirmation of the vehicle's roadworthiness and assurance that it is safe to operate before resuming driving.

Automatic emergency braking, for no reason, occurred twice while on autopilot. Driving on a remote interstate, during the day, no one and nothing in front of me (and I had a passenger that can confirm), and suddenly the car rapidly braked extremely hard. If I hadn't slammed the accelerator immediately I would have been rear ended the first time. The second time, no one was near me. I am attempting to report this to Tesla, although that is somewhat difficult as I am just getting bounced around their automated systems. My passenger and I, and the car behind us were put at serious risk of collision at ~ 85 mph, due to the completely unexpected and extremely rapid braking. This was under simple autopilot, no fsd or other driving assist. Nothing has been inspected yet, or reproduced past these 2 incidents. No warnings or symptoms occurred before or after this issue. Slightly terrified to use autopilot now, as if a semi-truck had been behind me, we would have been flattened. It is also difficult to turn off this so-called "assist" with emergency braking, it auto-reverts to on every start up, which is also dangerous.

My Tesla Model 3 disengaged cruise control while going 68 mph and braked hard for no apparent reason. I was driving northbound on I-405 at 3:45 a. M. Going to lax airport in the number 3 or 4 of six or seven lanes. Cruise control had been activated for at least 10 minutes before the incident at a speed of 68 mph. There was no traffic within half a mile before or after me due to the time of day. Neither my left or right foot were near either the brake or acceleration pedal, nor were they in motion. Both hands were on the steering wheel and no control was being activated. The only noticeable environmental condition is that the road surface had just changed from a dark gray asphalt to a bright white new concrete roadway. No emergency braking alert was seen or heard, so I do not think it was a false collision detection, and there was no car within a half mile. However, I do believe the severity of braking could have caused an accident if there had been someone behind me. Tesla Model 3 software version was v12 (2025. 20. 6 046c4575d120).

Vehicle must have thought a shadow line in the road from a bridge indicated a wall I was about to hit, as it slammed on the breaks in the middle of the freeway. Car behind had to swerve to avoid. On the same trip, several nags of 'keep eyes on the road' were incorrect, as my eyes were directly on the road, but phone was in hand functioning as a microphone taking voice memos. Car proceeded to shut itself down while in the middle of the freeway, causing me to go slower than traffic and put me in danger as cars behind me had to swerve or lane change to avoid me as I tried to pull off to the shoulder. These forced shutdowns from incorrect 'nag fails' are causing safety issues. Nag failures should not forcibly shut the car down. Not sure if this is being enforced by NHTSA, or why Tesla is choosing to disable their auto steer or fsd when drivers are detected to be failing nags - nags should be there to help drivers, and potentially the nag data/cab video can be used after the fact should a user failing nags be involved in an accident for insurance dispute resolution, but shutting the cars down themselves is causing issues.

Incident details: • date of incident: [xxx] • time: [xxx] • location: san antonio, TX • weather/road conditions: clear, dry highway; 90 f • speed: 60 mph; • description: while driving my 2021 Tesla Model 3 with full self-driving (fsd) software version 12. 6. 4 engaged, the vehicle unexpectedly changed lanes without my input, likely due to the auto lane change feature. Immediately after, it braked hard for and unrecognized slowing traffic ahead. This sudden jolt caused immediate pain in my upper back, neck, and chest, which persists. I believe fsd misjudged traffic patterns or road conditions, a known issue with v12. 6. 4 based on online reports. The incident occurred in heavy traffic and no crash occurred, but the abrupt braking posed a safety risk and caused injury. I’m unable to see a doctor today but plan to soon for a diagnosis. This is a serious safety concern, as fsd’s erratic behavior could cause collisions or further injuries. Injuries: yes, back, neck, and chest pain caused by sudden braking. No medical diagnosis yet; planning to see a doctor soon. Crash: no fire: no police report: no accident attachments: I have video information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I am filing an urgent complaint regarding multiple incidents involving my 2024 Tesla Model 3 (VIN: [xxx] ) that caused major safety risks, personal property loss, and serious disruption to my life. [xxx] – while in a left-turn lane with autopilot engaged, the car attempted to go straight. When I took over, the system malfunctioned severely. (photo evidence available) [xxx] – remote support failed; car towed to Tesla upland service center. June 27, 2025 – issued loaner vehicle. July 1, 2025 – Tesla claimed I must pay for repairs. I requested a written evaluation report, but to date it has not been provided. July 20, 2025 – without consent, Tesla remotely locked my vehicle with my personal belongings inside, violating my property rights. Aug 1, 2025 – Tesla promised review and report but refused to unlock my car. Aug 12, 2025 – after 10+ days, still no report. Upland “options” included threats that my locked car in my garage could be deemed stolen, causing severe mental distress. Demands: 1. Full investigation into autopilot failure and handling delays. 2. Immediate delivery of written evaluation report. 3. Accountability for delays, threats, and property rights violations. 4. Compensation for all losses and disruptions caused. Contact: [xxx] I request a written response within 24 hours. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was in a drive thru of a fast food restaurant and the car rapidly accelerated on its own and crashed into a wall. The air bags deployed and we were injured. We also narrowly missed hitting a pedestrian. The car hasn’t been inspected by anyone yet, however it is available if someone wants to inspect it.

I went to drop my son to a summer program to a park. After dropping him, as soon as I started, car just accelerated very fast and went on the sides. I was able to turn the steering back into road but it kept speeding and went on the other sides. In the process, cars tires got impacted. Within 5-10 secs, car got from one side walks to the other side walk and then car stopped somehow. Fortunately, it did not impact any other cars parked or other cars on the road. But the whole thing was very scary.

I have had this happen twice, once on city streets going to work the car was not in auto pilot and it went from 40mph to 0mph instantly. If there was a car behind me I would have gotten slammed into. The second time, my mother was in the passenger seat and I was on the freeway going about 75 to 80mph and it was on auto steer and the car went from the speed I was going to almost 0 and I instantly took control of the vehicle. We both could have been killed because of the last incident and I thought the cameras saw something on the road but there was nothing there. No cars were near me when both events occurred.

I was traveling at highway speeds on a highway with no vehicles or other obstacles in front of me. I had adaptive cruise control on. Then, the emergency brakes deployed for no reason (so called “phantom braking”), decelerating the car quickly. I turned off adaptive cruise control as fast as I could and nothing bad happened. But the situation was dangerous, as if a car was close behind me it could have rear ended my vehicle.

Attempting to park. Slowly inching forward while turning left. Vehicle accelerated. (sudden unintended acceleration: sua) vehicle jumped a curb, bounced off a tree, dropped off the curb before comping to a stop. Internet search shows other similar reports; attributed, by Tesla, as pedal misapplication. This was not "pedal misapplication". I am not looking for anything. But NHTSA should increment occurance counter by 1. Tesla has a problem. Electrical or mechanical. . . Do not know. They have also lost me as a customer. The car will be sold. I have video. . . Mp4.

Phantom braking (as it's referred to by experts) happened to me twice on the highway using traffic-aware-cruise-control. Very scary. I was on cruise control going 60 mph when suddenly my car braked suddenly and inappropriately, losing at least 20 mph in a split second before I was able to slam on the accelerator and prevent an accident (rear-end collision). This happened twice in the course of 5 minutes on the same highway! there was no obstruction in the road, no cars moving into my lane, nothing but normal road conditions, when it occurred. From my research, this is a huge problem with Tesla vehicles that thousands of individuals are loudly complaining about online and now in court cases in the country. I see there are thousands of reports to your organization about this, but it says you have only complaints from 2021 and later years. However, I have a 2019 and it's happening to me. And it's happening to every single model year out there, just from researching and talking to Tesla owners. This is a major safety hazard, plain and simple. I was inches of being in a rear-end collision, and drivers behind me are extremely upset and vengeful on the road after an incident like this (understandably!). Because of this I fear for my safety and well-being on the road using Tesla's cruise control features. Very disappointing. Above for the adas option, I wasn't able to select 2 options, but "automatic emergency braking" is also applicable here as that is what happened. Somehow Teslas are falsely activating emergency braking during cruise control!.

If you are on a hill and you accidently press both the brake an accelerator, the car will fall to neutral and free roll. In whatever direction is downhill. I have big feet. Happened again to me, I bumped the brake pedal (but not enough to apply the brakes to stop) when attempting to pull forwards slowly and my car beeped with the "both pedals detected pressed" alert. And then it free rolled backwards (because I was on an uphill). This will cause an accident because the car is not supposed to free roll backwards when in drive, this is a safety problem. It has been 4 years now, and no action has been taken to adress this software defect. A normal gas car does not do this. If you bump the brake in a normal gas car, it does not free roll in any direction. This is a Tesla software problem that Tesla needs to promptly fix ASAP!!!!!.

Wy wife and I drove our Tesla Model 3 from palo alto, CA to san francisco downtown, to meet friends. I was the driver, and my wife sat on the passenger seat. The weather was clear, and the pavement was dry. I did not engage auto-pilot features during the entire trip. The car condition was normal with no signs of error or warning. I made a right turn onto [xxx] from [xxx] shortly after I completed the turn, the car unexpectedly lost control. Without any prior warnings, it suddenly veered into the center divider, snapped a tree, dashed towards oncoming traffic on the other side of [xxx] , and finally stopped on [xxx] , labelled as location a on the attached drawing. Everything happened so quickly: I could not control the steering wheel, and I applied the brakes in vain. The vehicle seized control, no matter how hard I tried to stop it. I regained control of the vehicle at the intersection of [xxx] and [xxx] , and was able to park the car at location a. We were very fortunate and blessed that we did not hit people at the bus stop, that there were no cars in front of us, that the opposite traffic on [xxx] was stopped by a red light, and that the traffic was light on [xxx] without such luck, my wife and I, and probably others, would have been seriously injured, if not worse. Because [xxx] is one-way, we decided to move the vehicle to [xxx] , and parked at location b in the drawing. I called 911 and spoke to a female dispatcher. She asked us to remain at location b and wait for police officers to arrive. We waited there for almost 3 hours, but no police arrived. The dashboard display indicated that we had a flat tire(s). We called mobile tire services. After their inspection, most of our tires were alright, except the rim of the front-left wheel was badly bent, as you can see in the attached photo. The mobile tire service staff was skilled enough to carefully patch the damage and said it should be ok to drive back to palo alto. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 5.

As I was pulling into a parking spot with my new 2025 Model 3 Tesla, I removed my foot from the gas to slow the car - the appropriate way to do so which is called Tesla's one pedal driving. The car did slow but then suddenly surged forward at an alarming rate. I have 100% certainty that my foot was not on the gas at this moment. The car was stopped by a large concrete planter just in front of me, however, if that planter was not there, my car would have been through the glass of an office building or in a head on collision with another car in the lot. If there was a person walking into the building, they would have been dead. A witness approached me and mentioned that the car seemed to act erratically. I have been in touch with Tesla about the issue and am awaiting response.

This is the 3rd or 4th time I have observed sudden unexpected acceleration when at a full stop at a light while using fsd supervised (v13. 2. 7 just updated). It first happened 2 or 3 times on fsd v13. 2. 6 when mine was the lead car at stop lights. This time I was at a stop light but obviously not the lead car. The truck in front of me was blocking view of the traffic lights. Each time, I have hit the brakes immediately, so I don't know if the vehicle would stop on its own during these situations, but I have no issues with it safely braking at any other time. Other than this intermittent glitch, fsd has been flawless on the hw4 next generation computer, which may lead to driver complacency not expecting this. I am reporting for awareness & hopefully correction. I have mp4 video files of the incident, but I cannot upload them here.

The full self driving is very dangerous. I had several events that put me in danger. Like, going to the wrong lane. Going to the wrong way. Changing lanes that almost hit a car good thing I took over right away. It made the other car upset and honk at me.

I'm not quite sure what component was affected, some module of some sort got water in or near it that wasn't supposed to. It is available for inspection. Yes my safety and others was out at risk. Yes the problem was fixed by service center supposedly. Yes the car has been inspected by the manufacturer. There were no warnings. What happened was on 12/29 I was driving the car and out of absolutely nowhere a bunch of warnings came up including loss of abs, any and all safety features. And more importantly lost usage of brakes almost entirely when car came to a stop it was grinding and shakey. This problem all arises due to Teslas negligence when it came to installing a new windshield on the vehicle. As stated in messages below, they made a mistake while installing my windshield that caused this major issue to arise. They have offered nothing as a solution but saying that their error is supposedly fixed.
