2018 Tesla Model S Driver Assist & ADAS Problems

Recently right side blind spot monitor camera stopped working. As result, majority of safety features in vehicle has been disabled to include forward collision warning, adaptive cruise control, and many other safety features of the vehicle.

both vehicle displays have stopped functioning, therefore there is no indication of speed, remaining charge, blind spot protection, or back up camera. also, turn signals are non-functional. This is a safety concern to yourself and other drivers.

While driving both North (in the evening) and also South (in the morning) on [XXX] between Washington, DC and Richmond, VA I have experienced an issue with Tesla’s Auto Pilot that can be very dangerous and scary. While using the navigation system and with Auto Pilot on while in the left most line on this divided highway, the car made multiple attempts to steer into the Express Lanes even when the large gates are closed and the red lights are on to indicate that the Express lanes are closed in the direction of traffic. To counteract this, it is necessary to quickly take control of the steering wheel and to get it to cancel Auto Pilot, otherwise the car would go into the gates and cause an accident. This has happened to me several times when I was traveling in the left most lane and when the gates were closed. This happened in November, December and in January. The system has not learned to handle this situation and to avoid steering into the barriers. I reported these incidents to Tesla’s Support Team by phone and after several weeks I received a phone call whereby the local service center (Rockville, MD) called me. Josh, the person that called me read a lengthy text to me that essentially reviewed the driver’s responsibilities when using Auto Pilot. I asked if there was any indication that they will work on fixing this issue and I was told that the explanation I got (which was no explanation at all, just a reminder of driver responsibilities) was the entire response. I informed him that I would report the incident to NHTSA. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving in Autopilot mode, approx 70 mph in light rain the vhicle began to drift side to side almost crossing over the lane dividing line. Upon grabbing the wheel to take control the vehicle entered multiple 360 degree spins crashing into "K" rail. In the past I have noticed when taking control of the vehicle from Autopilot the wheel jerks.

In July 2024 all the cameras on the Tesla Model S except the rear stopped working after a failed software update. This meant that all of the driver assistance systems as well as GPS, adaptive cruise control, blind spot monitoring, lane departure warning, forward collision warning etc stopped working. The lack of availability of this system meant that the car no longer had any advanced safety features that came with the car. It took many months for Tesla service to diagnose and fix the problem, which they identified as a failure of the Auto Pilot computer. After I was finally able to get an appointment with the Service center, they replaced the Autopilot computer at a cost of over $1500. The failure first appeared in July 2024. The symptom was GPS location being stuck and Autopilot and all safety features being not available.

On the afternoon of [XXX], my car’s speed assist was set at 30mph, and I was traveling north on [XXX] . At the end of that avenue where it joins [XXX] , a red traffic light was detected and my vehicle stopped normally. However a unique anomaly occurred. The vehicle crept forward three times against the light. I was required to apply brake pressure to stop the car from moving forward illegally. This phenomenon has never occurred since I have owned the vehicle beginning in early 2019. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Shortly after an update in December, my 2018 Model S started getting alerts: Driving visualization temporarily degraded, charge port sensor fault, autopilot cameras unavailable, automatic emergency braking unavailable, lane departure avoidance features unavailable, steering assist reduced. The map no longer knows where the car is located and cannot navigate or tell what the battery percentage will be at. All automatic features have stopped working. The service center claims the ECU needs to be replaced. It was upgrade to the Autopilot/Full self-driving ECU in 2020. I have read reports from dozens of other Tesla owners that this update also broke their ECU. I believe Tesla knows the new requirements for full self-driving to be safe and usable does not work with their current ECU. They want to charge me $1600 to replace the ECU. I cannot receive the recall OTA update with my current ECU.

My car will randomly apply the brakes when driving on the highway for no apparent reason. I have noticed this to occur when going under overpasses especially on a bright sunny day, but also at other times. I do not find it to be predictable and it can be quite dangerous if traffic behind me is very close. This has occurred many times, most recently as yesterday.

Multiple components failed or malfunctioned. FSD beta, lane keeping assistance, lane departure warning, adaptive cruise control, and Automatic emergency braking, all failed or malfunctioned. I have requested TESLA to provide me the details on what happened, but after multiple attempts of reaching out to them, they are not providing any answers. I was driving with my son and we both got injured, my son was admitted to the hospital for 4 days. I am not sure if TESLA inspected it, they are not answering my questions. There was no warning or there were no symptoms of the problem before the failure. This is what happened, I was driving on FSD beta on a 2-way street with one lane in both directions, The car suddenly drifted, crossed the opposite lane, went over the sidewalk, and hit a tree. The airbags were released, and the front of the car was destroyed. The speed limit on the road was 25, and as it was in FSD mode, the speed was locked in at 25 mph. I was driving with my son, and my son got a lot of bruises internal and external from the seat belt, I had some bruises on my forehead. This is a complete failure of Tesla's FSD capability because it didn't detect the tree or the sidewalk and failed to apply the brakes. The car was declared a total loss by the insurance company. I am attaching a few photographs of the car after the accident.

The contact owns a 2018 Tesla Model S. The contact stated that while driving at an undisclosed speed, the forward collision avoidance feature was inoperable. The contact stated that due to the failure, the vehicle crashed into the guard rail. The contact stated that damage was done to the front driver's side and rear driver's side of the fender. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 80,000. The VIN was unavailable.

I was using the Enhanced Cruise Control and the car just slammed on brakes out of nowhere. There was not any cars ahead or beside me at the time. This has happened about 5-6 times since I purchased the vehicle on March 10, 2023

While driving on the highway using cruise control, the car unexpectedly and rapidly slowed down. This has happened several (5-10) times, day and night, generally in low traffic areas (mostly with no traffic anywhere nearby). I have experienced this issue throughout my ownership of the car. In the most recent case, the car seemed to think that the speed limit had dropped to 35mph, perhaps seeing a sign from a nearby road. Other times, I could perceive no cause, so UNKNOWN. The date below is the most recent time, where the car thought the speed limit dropped.

I was using the vehicle's traffic aware cruise control, but not autopilot and the vehicle experiences sudden braking without warning or reason. I had no other vehicles near me, on a straight, flat road with no bridges, signs or other things to cast shadows. The weather was sunny, but the sun was not shining on the front of the vehicle. The most extreme instance starting braking the vehicle from 84mph and the vehicle reached close to 40mph before I could overtake the system by pressing on the accelerator. My passengers were thrown forward as well as our items within the vehicle. I'm thankful there was no vehicle behind me that could have rear-ended me. There is no reasonable way to contact the manufacturer other than asking for a service appointment which can't fix software errors. The manufacturer should provide an option for basic cruise control.

Repeated problems with "phantom braking" when adaptive cruise control or autosteering is engaged. The vehicle would make unexpected hard breaking without any obvious triggers. In the past, I have made multiple "report bug" to Tesla immediately following phantom breaking, but no improvement noted thus far. This problem recurred yet again on I-5 today; the vehicle suddenly made a hard break despite absence of any issues in front of me; this resulted in the vehicle behind me having to take immediate evasive action by breaking and making a sudden lane change to avoid a collision.

Door handle not working and not popping out as expected and driver can’t go inside the car. A few complaints already from the internet and a lawsuit already filed by other owner and this seems to be recall already but nothing was mentioned yet Camera get blinded or get block easily with rain or sun. This is an issue if you’re using the autopilot.

On 3/15/2022, I was driving on I405 with auto-pilot engaged. My car (Tesla Model S) suddenly braked hard for no apparent reason. I had to disengage auto-pilot and quickly accelerate to avoid the car behind me from rear ending my car. Fortunately, I remembered to save the event recorded on Tesla cameras. Take a look at 2022-03-15_12-24/2022-03-15_12-24-53-back.mp4 file around 46 sec ~ 51 sec within the file. You will notice that the car suddenly braked around that time causing the car behind to nearly rear-end my car. If you watch recording from the side+front cameras around the same timeframe, you will notice that there was nothing in the front or on the sides that warranted sudden braking. Those files are 2022-03-15_12-24-53-front.mp4, 2022-03-15_12-24-53-left_repeater.mp4 and 2022-03-15_12-24-53-right_repeater.mp4 The Tesla app does not allow me to create a new service request for this issue because I have another request open for a minor and unrelated issue. Therefore, I have not been able to report this to Tesla. I will do so after 3/22 when the current request is resolved. Note your site does not allow uploading video files therefore I could not attach them to this report. I can make them available if you need them.

Operating vehicle on highways while utilizing Autopilot and/or Autosteer(FSD) braking will randomly occur without any warning. This is commonly referred to as “Phantom Braking.”

Hello, I am a Tesla Model S owner for the past four years (bought it on june 15, 2018) and I absolutely love my Tesla and its autonomous driving auto pilot. It generally performs well except for a very serious glitch of Phantom braking when approaching overhead bridges / passes. When on autopilot, many times when the car approaches an overhead bridge / highway pass or train bridge running perpendicular to the highway, the car will abruptly brake very hard and give warning for forward collision. I think this started happening after Tesla modified the auto pilot software in the wake of a collision between a Tesla Model S and a tractor trailer that was perpendicular to the car in sunlight and that killed the driver. Now very often the software mistakes the bridge as a big tractor trailer or something that is about to be hit and jams on the brakes, greatly increasing the risk of my car being rear ended by another car from behind who on an empty highway has no reason to expect me to brake suddenly (in fact I have no reason to expect it either). I reported this to Tesla engineers on phone and during routine service and they said they could not replicate it and instead asked me to report such incidents when they happen by using the voice command button on steering & say "Report Bug", which automatically transmits all logs of car for the last few minutes to Tesla engineering directly. I have been regularly reporting such phantom braking incidents to Tesla this way (which I think is actually another really amazing invention by Elon Musk, kudos to him), but not sure if they have taken action on this as it still happens once in a while and is very scary. Again to clarify, I love my Tesla Model S and am a huge fan but really worried that this phantom braking of my car, which I have after four years of driving my Tesla, noticed ALWAYS happens when the car is approaching an overhead pass or bridge, is a HUGE safety risk and hope you can convince Tesla to fix.

Without warning, the car will phantom brake at highway speeds at least once or twice on every highway trip I take. It will slam on the brakes automatically even though nothing is in front of the car, putting us at risk of losing control or a rear end collision if someone is following closely. This has been happening since I purchased the car in 2018 until I sold it in late 2021. Tesla cancelled my mobile service appointment about this issue, saying this is "normal environmental conditions" without even looking at the car. I have since sold the car due to this issue and frustration with their response, but wanted to report the safety issue here.

Driving west on Interstate 295 at the Scudders Falls bridge from NJ to PA, adaptive cruise control suddenly slows from a set speed of 65 to a set speed of 30, then restores to 65 after a second or so. This predictably and repeatedly happens just before and just after the bridge itself, at locations 40.26068356165738, -74.84459141709418 and 40.25572592962884, -74.85316191866097. I have reported this to Tesla a couple of times over 6 months or so but with no improvement. As mentioned, it is 100% repeatable, in any of the 3 lanes, regardless of weather or traffic conditions. It happens with no other nearby vehicles, so it is location based, not conditions. It could be extremely dangerous if someone did not expect this and a vehicle was close behind.
