Adaptive Cruise Control Problems of Tesla Model X - part 2

The full self driving system failed to operate correctly. This caused my car to hit another car. I have asked Tesla for the data they use to tell what the driver was doing when the system was on but the Tesla staff who respond to my requests plead ignorance of what data I am referring to. I am not ready to spend the money it would cost to hire a lawyer to force Tesla to hand over the data from their system. I have video from the Tesla camera showing what happens. I will try to upload it. Here is a quick run through of what happened: I entered the freeway and got into the left lane. Once I was safely in the left lane and up to speed I turned on the fsd keeping my hands on the steering wheel. After a few moments the car veered to the right, I tugged against the pull of the fsd and got it back in the lane when all of a sudden it turned my wheel hard right into a minivan. It happened so fast that the wheel turned even with my hands on it. I have been trying to talk to someone at Tesla but it is difficult to break through the front lines as they deflect contacts away from anyone who might be able to answer my questions about getting the fsd incident data. The video is . Mp4 so it is not allowing me to upload. Please let me know how to send you the video.

Using Tesla autopilot I was passing a semi truck on ohio turnpike and as I was right next to the semi truck my Tesla suddenly started to flash red warning light and make a loud squealing sound and began to rapidly decelerate. Luckily no one was right behind us or likely a rear collision would have occurred. The semi truck was a little closer than normal to me but was still within its lane. This happened twice that day so I stopped using autopilot as it was dangerous and very frightening to me and my passenger.

At around 9:10 p. M. On 7/26/2023, I was driving 2 guests on the I-5 highway from seattle to the airport. The car’s automatic driving assistance system suddenly failed to work. Tip 1: the steering assistance effect has been reduced 2: lane departure avoidance function is not available; at this time, the steering wheel suddenly couldn't turn, and I felt locked tightly, unable to change lanes, so I had to slowly reduce the speed, turn very, very hard to change lanes, from the innermost carpool lane to the outermost exit lane, slowly the driver controlled the steering wheel hard, and it was impossible to drive on the deceleration road when getting off the high speed. When encountering an intersection, I couldn't turn to the normal driving lane at one time. I drove about 15 miles like this, and put the passengers down at the airport. I slowly drove to the 76 near the airport. After parking the car at the gas station, I searched online to see if this happened to others? at the same time, press and hold the ball button on the steering wheel to restart the screen, and found that the situation did not improve, and the steering wheel was locked tightly. I got out of the car and found that the tire pressure of the four tires was all at 40psi, which was probably related to my hard twisting of the steering wheel. I restarted tried a factory reset, and after it reset to factory settings, the situation didn't get any better, it was already 11:00 pm, I wanted to fill up the tires to 45psi first, and then called a rescue tow truck, at this time I found that the steering wheel was unlocked , it can be turned flexibly, and after filling up the gas, I went home and upgraded the system again. Thinking about this kind of thing that happened suddenly , I was still in palpitations and almost didn't dare to drive it out again. What's going on in this situation? will this security risk happen often? how to handle it correctly?.

I was driving on the highway on Tesla enhanced auto pilot when traffic came to a stop I’d notice my Tesla Model X was not about to stop nor slow down for the stopped traffic so at the last minute I had to slam on my brakes and swerved to the right lane where I was hit by a truck pulling a trailer which subsequently rammed me into the truck I was trying to avoid rear ending after Teslas forward collision warning failed to notify me or stop the car from crashing in the first place.

I have driven this vehicle approximately 28,000 miles. I am the original (and only) owner. When using the cruise control the car will break suddenly and aggressively for no apparent reason on the open road. This has happened more than a dozen times. I cannot say what percentage of my driving is done with adaptive cruise control functioning but I would suspect well less than 30% of the 28k miles. On several occasions I surmise it my be related to oncoming vehicles in their normal lane. Fortunately, these episodes have not resulted in any collisions to date.

Mcu1 fsd beta still not working and nothing has been addressed from Tesla. Tesla states we will mcu1 will be supported for fsd.

I paid for fsd and now Tesla has disabled the feature. They have not responded to any inquiries by me as to when it’s going to be reactivated. I would appreciate anything that you can do.

While driving on autopilot, adaptive cruise control essentially, on a 300 mile trip last week the car had several, I think 5 total, instances of phantom braking. These occurrences happen in random situations, no consistent factors that seem to indicate what triggers it. It is often not only startling, but scary since it is almost always in a high speed situation with traffic. These events have happened in the past but not at this frequency. We have another Tesla, a model 3, that also experiences this same phenomena. When I reported it to Tesla they said to reboot the system, which I did. Did not appear to improve. Otherwise they seem to be unconcerned about these events. I have had adaptive cruise control in other cars, mostly Lexus, where this never occurred.

Two issues that are concerning and I have told Tesla: 1. The car will be on cruise control and I will be relaxed and all of a sudden it will just brake for no reason. Praise god I am aware of it now and prepared so I have to compensate, but it is very dangerous and made the cruise control useless. While it was under warrantee I request it be fixed, but they said there was no way to do that. 2. The car's back up screen is compromised and has a distortion on the bottom that was caused by a download. I requested four separate times a service requests to fix it while it was under warrantee, but they were unable to repair it. The first time they said I needed to wait for a download, then the second time they said it was a hacker, third time they replaced a chip, and the four time they told me to repair it I need to upgrade my entertainment package for $1500 so I cancelled the appointment. All while I was under warranty. Four appointments later and I still have a distortion on my screen when I back up which is slowly getting larger and will be a safety issue I'm sure down the road. Two very obvious safety issues that while under warranty they would not fix. I wrote Tesla and asked them to review my service requests and to get some resolution. I was unsuccessful.

When using cruise control the car decides to randomly hard-brake dropping instantly 40+ mph or it increases speed higher than the set cruise control for no reason. We literally have had our bodies slammed into the seats during braking and we will inevitably be rear-ended for this faulty “phantom” braking. We submitted a service request to Tesla on 5/18/23 and were told there’s nothing to be done because it’s in beta testing. This is dangerous and unacceptable. Almost all new cars have adaptive cruise and those other brands have figured this out. Tesla ignoring this and basically saying “it’s not our fault” is irresponsible.

Repeatedly, I have had my car brake harshly when travelling anywhere from 30-55 mph while using adaptive cruise control. There is nevere anything in the road or a car anywhere nearby to warrant a dramatic braking. The decelertion is harsh and alomst caused someone behind me to hit me on 2 occasions. I have repeatedly told Tesla about this and mostly gotten a nebulous response about "hardware" or 'software" issues and that they are working on it. This is dangerous and hurts when it unexpectedly happens!!.

Random phantom braking while on the open freeway with no traffic while in cruise control. It happened multiple times while on a road trip. There was not an obstacle or traffic in front of us. Braking was hard almost to a skid.

Driving using full self driving mode, I've had at least 3 instances where, when merging onto a limited access highway, the car does not merge into the through lane at the earliest possibility, but rather goes to the end of the on-ramp before moving into traffic. At this point, I've experienced the situation where I'm steering in front of a vehicle that is overtaking me in the through lane. Furthermore, the car does not activate any turn signals; a traffic violation in new york state. (previous versions of fsd did not exhibit any of these characteristics. ) current vehicle software is 2022. 45. 15, fsd version v11. 3. 6. (I have been unable to contact Tesla by email about this matter. ).

On a recent 2000 mile trip, we experienced several (10-20) incidents of unnecessary, very strong braking. There were no apparent reasons for the very strong braking episodes. In some instances, there were no cars in front of us and no cars behind us for many miles (I-40, new mexico). Braking was so severe that it likely would have caused a collision if cars had been closely following us. We have traveled this route several times in past years with no similar emergency braking incidents.

The latest update of the full self driving software, version 11. 3. 3, significantly decreased the safety of the car and increased violations of the driving rules. 1. The car frequently turns on turn signals near intersections without making any turns. This misleads other drivers and may lead to an accident. The problem is extremely frequent in the specified version of software. 2. The car ignores electronic speed signs installed in high-risk segments of the freeways (e. G, I-5 in seattle, wa). Then, it breaks late approaching stopped traffic. This creates a significant risk of an accident - especially, on the back, when the car breaks aggressively. 3. The car turns to the hov line when on autopilot even though the “use hov line” setting is switched off is the settings (e. G. , on sr-167 in washington). This has never happened on the previous versions of software. 4. The car often reads speed signs for trucks as applicable to a passenger car (e. G. On I-5 at night or in rain). This was also reproducible on the previous versions of software.

When autopilot is engaged, the car randomly decelerates on the highway. This has happened multiple times. I have tried to report this to Tesla but to no avail. They tell me the following: 1. They are unaware of any issue 2. Then, it is my specific car's problem and not a design issue and they will not fix it without charging me over a $1100 3. When I asked them what the issue is, they said they don't know and want me to provide to the minute detail on when the incident happened. 4. That I should stop using autopilot (which I paid for) because it may be unsafe for me to use. When I point out that their statements are conflicting with each other, they ignore me. I have tweeted about this to elon musk as well to NHTSA and I am hoping that someone will notice this and help me get this fixed.

Traveling south on I 5in CA on 2/27, weather and road were clear, speed 70 mph, the car suddenly ceased to maintain it's set speed and decelerated rapidly. At 70 mph with vehicles right behind me closely following, this is safety hazard. Same problem on return trip home northbound on CA 101 - destination brentwood, CA. Third occurrence was on CA 246 - same problems but at 60 mph.

While on regular cruise control (not autopilot), our Model X will abruptly decelerate. This has happened before. Usually on highways I. Road trips.

Several times, while traveling north on the i15 express lanes in rancho bernardo, CA, with the full self driving beta software engaged, the Tesla unexpectedly brakes when going under the overpass located at the george cook expressway exit. I must keep my foot over the accelerator pedal so that I can override the braking, if necessary. It appears to happen about 50% of the time.

On the date of January 4th, at approximately 6:50 pm, while using the autopilot feature on my Model X, I was driving 55 mph on the highway and the phantom break occurred, which it completely stopped my car but I was fortunate enough there wasn't any car behind me and I was able to speed up quickly avoid any accident.

2022 Model X plaid is exhibiting “ phantom braking” while in autopilot mode using navigation. Vehicle abruptly brakes while driving on highway as navigation appears to become confused and thinks it is on a side street. Vehicle goes from high speeds of 70-80 mph, down to 30-40 mph. If was being followed closely, car behind Tesla would have collided with rear of vehicle. This has occurred 10+ times since purchased vehicle in February. Vehicle has just under 6000 mi. As of today. I have times/dates to include a video of one incident. I have brought it to Tesla for service on 2 separate occasions, to no avail. They say it needs the latest upgrade, which has not resolved issue.

When pass under over pass, at the speed of less than 50km/h. It breaks for no reason.

After I started an update as requested on Tesla app, the car was giving error messages. I was able to drive but the errors were - 1. Reduced steering assist 2. Autopilot and cruise control not available.

About 224 miles n. Of los angeles, on I-5, southbound, the car aggressively braked while using traffic aware cruise control. Speed was around 75 when braking started. Speed dropped to 55 mph at the end. There was a couple additional brakes on this southbound journey. I can't believe that Tesla thinks they can implement full self driving when they can't manage to maintain a constant and not jarring speed. This is a recipe for disaster.

Highly repeatable issue: driving on left lane of a highway going at high speed (60) with adaptive cruise control enabled (but * full self drive mode). Put on turn signal to merge into right lane. There was a car in the right lane directly next to me but I had not initiated the merge, was merely signaling my intent to merge. My car slammed on the breaks (very dangerous as I was almost rear ended the first time by a 18 wheeler). Did some testing at a later date- if there is a car slightly ahead of me in the right lane, the car behaves normally (maintains speed) if there is a car in my blind spot, the car indicates there is someone in my blind spot but maintains speed. If I am driving in the left lane all three scenarios (slightly ahead, directly adjacent, in blind spot) the car maintains appropriate speed. It is only when car is directly adjacent when in left lane w/ right turn signal that car always now will slam on brakes. Very dangerous- Tesla has been made aware of the issue 2x now- and had informed me that “it is beta software (?????!!!!!!) and to live with it. ”.

We were driving down the freeway in daytime sunny weather on “autopilot” (I was actively monitoring the vehicle of course) when the car slammed on the brakes for no reason. It was aggressive and fortunately I disconnected the driver assist “autopilot” and immediately pressed on the accelerator (not an intuitive action) to avoid causing an accident. There was no reason for the car to behave this way. Furthermore, Tesla updated the software recently on my vehicle. I purchased the vehicle with radar, whereby it would use the radar as an input in coordination with other information for the adaptive cruise control and auto steer. (collectively called the “autopilot” by Tesla. This recent software update took the radar out of the equation and made my car function differently (less robust) by now only using the cameras and not the radar. The cameras on my model year are not, to my understanding, of the same capability as the cameras that Tesla is using with their newest models. Despite the cameras being older, Tesla modified the vehicle via over the air software update to only utilize the cameras, again, despite the car being designed to utilize the radar as an input to the semi autonomous driving. I take great issue with Tesla retroactively reducing the capability of my semi autonomous driving and not providing a warning or a clear choice. The phantom braking I experienced was after this software update that removed the radar. It’s one thing if a driver needs to be prepared to brake, but quite another if the car brakes extremely aggressively and the driver has to rush to press the accelerator, all while startled. I work as an airline pilot and this seeming total disregard for safety, removal of radar input that the car has on board already, and lack of transparency to the driver would never be accepted in aviation. I urge the NHTSA to look into the aggressive uncommanded braking. Thank you, stefan.

What component or system failed or malfunctioned, and is it available for inspection upon request? -- cruise control system (with or without full auto-pilot engaged) how was your safety or the safety of others put at risk? -- vehicle comes to a near complete stop from highway speeds, in traffic, to avoid 'something' that doesn't exist has the problem been reproduced or confirmed by a dealer or independent service center? -- no, but can be reproduced on highway 54 between el paso, TX and alamogordo, nm has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -- no were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - no, problem has occurred since April 2022 after receiving the full self-driving beta software update. Description of problem: vehicle is suffering from the well known "phantom braking" issue and appears to be getting worse. The problem can be reproduced 100% of the time on highway 54 between el paso, TX and alamogordo, nm. With cruise control activated and set to 75 mph (auto-pilot disengaged), vehicle will hard brake to 45 mph or less and then resume back to 75 mph; essentially "brake checking" the vehicle directly behind. No injuries or accidents to report at this time.

Sudden acceleration.

I have my car in service right now for a recall that needed a replacement emmc. On a service that was estimated for 2. 5 hours have now gone on to 2 weeks. They also marked this recall service as complete within week 1 and tried returning the vehicle with errors pertaining to the emergency brake system, autopilot, sentry security system, and a list of other errors that came from the software not downloading properly and therefore, not installing the new emmc correctly. Because this service was marked complete, I am no longer able to pull up with recall with my VIN # and I just wanted to document this to ensure this is fixed properly. I am now told by Tesla that I need to pay $1500 for a new infotainment system or $1600 for a new das system in order to address the recall issue. Looking back at my recall letter, there is a section that lists "if you believe that Tesla has failed or is unable to repair this defect without charge or within a reasonable time, you may submit a complaint to the administrator, national highway traffic safety administration" which I'm doing now. Please let me know if there's anything I can do to have this recall properly addressed. They are now attempting to revert the car back to the original aftermarket emmc in order to return the car to me without addressing the recall.

"phantom braking" of the Tesla optical-only (no radar or lidar) adaptive cruise control. Northbound on hwy 101 around gonzales CA there is a truck stop on the west side of the highway. Proper signage and lane lines enable 101 traffic to maintain 65 mph. The insufficient optical-only system hit the brakes through the intersection and caused traffic behind me to brake suddenly as if there were an obstruction. I scheduled service but this is a system that should be tested much more rigorously before delivery. The sudden braking that the system employed caused a situation where driver input was required to avoid a collision. This is inherently dangerous and is avoidable by peers' acc systems. Has not been reproduced to my knowledge. No inspection of the system. Yes, there is an audible alarm that the system is braking. Too little, too late. One final thought: the acc systems of vehicles in this class use radar and/or lidar to enable sampling of the entire electromagnetic spectrum that humans can monitor cost-effectively. For some reason Tesla made the insane decison to go optical-only, robbing their system of at least 10 times the data. The detriment in available data that an optical-only system has to overcome is too great to solve with nifty software. Tesla's decision endangers drivers of their cars and, most importantly, others on the road.

Recurring phantom braking every drive.

I was driving my Tesla on left line of i75 norh with 70 miles speed. It was on autopilot . Without any warning car lost the control and slipped, changed three lines and collide at the right side median . It’s happened on 3 July 2022. I reported the accident to Tesla right away. The accident took place more than 6 months and still Tesla is saying they are studying the car and not giving a clear report. So the repair people doesn’t know how to fix it and I am out of car. Please investigate the case and help me to get a report so that I can fix the car.

Sudden dangerous breaking for no reason with near rear end collisions. Happened several times while on a road trip while on highways and also when trying autopilot on highways.
