2017 Tesla Model S Driver Assist & ADAS Problems

The contact owned a 2017 Tesla Model S. The contact stated that while starting the vehicle, an Autopilot disabled warning message system was displayed a day prior. The contact reached out to the Tesla hotline for assistance regarding the failure. The contact was advised to continue driving the vehicle, and the system error message was expected to clear. The contact stated that after multiple drives, the warning message did not disappear. The contact stated that while coming to a stop, the brake system became inoperable. The contact stated that the vehicle then accelerated to approximately 35 MPH, causing the contact to rear-end another vehicle. Multiple warning messages were displayed, including: traction and stability control disabled, automatic emergency braking system fault, battery management system critical fault, and electrical system reduced, as reported through Tesla chat assistance. The contact also stated that all air bags deployed. No injuries were sustained, and no medical attention was provided. A police report was filed. The vehicle was towed and deemed a total loss. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 98,787.

Software version 2025.32.3.1. Using Tesla’s auto-steer / enhanced autopilot (not fsd) causes many “phantom braking” events when going through several intersections on my commute. It’ll say a message “Curve Assist Active”, however I’ll be on a very straight and flat road with no curves. It’s 65 mph road and it will brake / slow down the car very hard and fast, if I don’t catch it in time it’ll get down to ~45 mph within a second. Even when traffic is going slow already, like 40 mph, it’ll still bring up the message and try to brake and slow down, though not as hard. Typically to about 25-30 mph. I usually can catch it and use the accelerator to prevent it, but sometimes it’ll happen so sudden and I worry about getting rear-ended by someone behind me. Very repeatable. Very startling and concerning when it happens when I don’t expect it to. I believe it’s a mapping issue as it has not been fixed in over a year and after several software updates.

The contact owns a 2017 Tesla Model S. The contact stated that while driving at an undisclosed speed, the Forward Collision Avoidance system became inoperable. There was no warning light illuminated. The contact stated that the Forward Collision Avoidance feature failed to activate, almost resulting in a crash with another vehicle. Additionally, the contact stated that the back over collision avoidance system was inoperable. The vehicle was taken to the dealer, where it was determined that the front radar and bracket had failed and needed to be replaced. The vehicle was not repaired. The contact expressed a concern that the failure posed a significant safety hazard, as the Forward Collision Avoidance was inoperable. The manufacturer was not made aware of the failure. The approximate failure mileage was 66,573.

Using software version 2025.14.1 with FSD (Full Self Driving) version 12.6.4. About 50% of the time the vehicle attempts and fails to change lanes when using FSD. It will: 1. Turn on signal and not change lanes, confusing cars around me. Or more often 2. Swerve between lanes indefinitely. See example at [XXX] It drives like a drunk driver. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Stoped at intersection. While trying to engage signal lights, hit the stalk below that engages full self driving. Car immediately jumped into intersection .in front of another car and almost collided. Since the last update, Cars with my configuration wave been acting irradely and it is not safe to use FSD.

I used Summon on [XXX] to bring my car to me because it was parked way at the end of the parking lot at Discount tire. There was only 1 car in the whole lot, which was parked next to my Tesla. While using the “come to Me” feature in Summon – My Tesla pulled forward and then turned and drove right in to the car parked next to mine. It did quite a bit of damage to my Tesla and the Mercedes parked next to me it ran into. When I called my local Tesla Service Center in Austin to ask what I am supposed to do, they told me they needed to run diagnostics to see if they can fix the “summon” issue. After running diagnostics they blamed the issue on the wrap I have on my car. They did not test the sensors obviously though, because they work fine through the wrap. Not to mention that Tesla offers wraps from the factory now. They also stated that Summon was aborted due to collision, so it did report their was a wreck. Repair Notes: The proximity sensors on the vehicle are being obstructed by the vehicle wrap, which results in interference or compromised sensor functionality. This interference can disrupt the accurate detection of surrounding objects, impacting the vehicle’s ability to engage safety features like autopark. Data analysis reveals that the autopark function was aborted during collision, due to the seat belt not being fastened at the time of the incident.

Computer software failure. Intermittent problem that started with a recent software update. When backing out of a parking space, car will move a few feet then go into park and set the parking brake. Putting car back into reverse allows the car to move about 2 feet then the parking brake re engages. This has repeated more than 6 times in the process of backing out of a parking space. (There was at lease 3' of clearance to the sides of the vehicle and nothing behind the vehicle.) This is very dangerous when backing out of a diagonal parking space that is along the side of a busy road. I have scheduled Tesla service for the soonest appointment which is 2 weeks from now.

I activated Tesla's Smart Summon feature on the 2017 Tesla Model S to autonomously drive from the parking spot to the front entrance of the restaurant where I was waiting. Pulling out of the spot (my car was back in), the vehicle prematurely turned and contacted the front bumper of the adjacent vehicle (also backed in). My vehicle proceeded for a few feet causing severe damage to my driver side and the other vehicles bumper. I entered my vehicle and pulled away from other vehicle which is still in contact with. Take document with photos, I returned my vehicle to the location where it occurred (except not in contact). See photos. I contact that evening and they spent the next week investigating. They disavow and responsibility and said I was supposed to monitor the progress. The incident took a few second and there was not time to react to avoid damage.

I received a safety recall dated 2/8/2024, recall no 23V-838. Tesla has failed to remedy the defect & claims a remedy is not necessary. Specifically, I took my vehicle to Tesla on 3/18/2024 to update vehicle software to incorporate additional autosteer controls. See attachment: "Repair notes: "No update necessary", despite the vehicle running a software version less than 2023.44.30 as specified in the Recall Notice.

Recall 23V-838; TC2023-657. Tesla not providing software update for recall from last year. I can't get an update for this recall unless I pay $2000 for MCU2.

See attached document for complaint

Tesla has failed to provide the software updates to fix the recalls on my and ALL other MCU1 cars that have FSD paid for. This is because Tesla has not delivered sent FSD to these cars, and hopes owners will pay $2,000 to upgrade to MCU2. Tesla has LIED that all cars with FSD paid for will be upgraded to the required hardware necessary to use FSD. This has now became a safety issue as recalls are not being addressed!! Tesla States vehicles should be running software version 2023.44.30 or later... We are stuck at 2022.8.10!

The contact owns a 2017 Tesla Model S. The contact received notification of NHTSA Campaign Number: 21V035000 (Back Over Prevention, Visibility, Exterior Lighting) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that while reversing at 5 MPH, the back over prevention camera showed a completely black screen. The dealer was made aware of the failure but confirmed that parts were not yet available. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 86,000.

1. Previously listed Recall has been erroneously removed from Recall history for my VIN. I had tried to escalate this via Email and Twitter with no response from NHTSA, Sources: https://www.tesla.com/support/recall-fsd-beta-driving-operations Note: The remedy is not yet available for vehicles with NVIDIA® Tegra® and will deploy OTA once the software is available. 2. The car continues to make unsafe lane changes during left or right turns and struggles to make a smooth turn and is hazard for vehicles behind the car when making such turns as it makes suddent stops.

An issue with "Pahtom Breaking." My Tesla Model S has suffered from phantom breaking since I purchased the vehicle. I have repeatedly mentioned it to Tesla repair representatives and am still waiting for a fix. The risks exceed those of operating a car—a danger to me and others on the road. Vehicles following me have no idea that my truck will randomly slam on the breaks. Even if following a "safe" distance, the Tesla stops so fast that driving at highway speeds, others cannot react in time to prevent an accident. This is an undone and unknown burden for other drivers as it is for me. Tesla must step up to the plate and correct this before people die.

5 times on a cross country trip, I experienced the phenomenon of "phantom braking" . As I was driving with Adaptive Cruise on, doing approximately the speed limit, the brakes were automatically applied and the car started to rapidly slow down. Luckily there was no one behind me so I was not rear ended ! I immediately took the car to the local Tesla service center thinking there was a problem with the car, but they told me this is a know issue with no solution at present. One tech told me he has a Tesla himself and has experienced the same issue ! He told me that he just punches the accelerator and keeps on driving !

On December 26, 2022 I was driving my Tesla S 2017. Full self driving was engaged. I have a video of the car footage showing the incident in full detail. The car took a left onto a 2 lane road and then without warning ran off the road hitting the curb and a metal drain. The force was so great that I suffered a contusion to my right knee from hitting the under side of the dash.

On 10/25/2022 at approximately 2:54pm I was traveling north on I-5 through Salem Oregon in the middle lane. Autopilot was engaged as I approached slower traffic 1 block in front of me in the middle lane. A pickup was approx 1 block behind me in the left lane. I activated the left turn signal. The vehicle initiated the transition from middle to left lane. Halfway between both lanes the vehicle applied hard braking action while continuing forward halfway between lanes. I tried to take over with application of the accelerator and force on the steering wheel to return to the middle lane. The steering wheel fought against me and the vehicle made a series of s-turns while braking. I tapped on the brake pedal and the system deactivated. The vehicle decelerated from 65-70mph to what I would guess to be 20-25mph with maximum braking (objects in the cockpit flew forward). The pickup behind me was very close when I regained control. If any vehicles had been closer or had the roadway been slick, the incident could have caused a major accident. I filed a ticked with Tesla and they advised this was known as a "phantom braking" event. There is no known fix, timeline for a fix, or mechanism to advise when there is a resolution. Tesla closed the service request. I'm a commercial pilot (former Part 135 Captain) and former flight instructor. I've been driving for 38 years with zero accidents. I have not used the Tesla autopilot since this incident. It is not safe in the current configuration. Tesla tech characterized the vehicle response as "conservative". There is no reason for maximum braking when nothing is in front of the vehicle. I would like Tesla to provide me with updates on resolving whatever is causing this. I would like Tesla to provide notification when the software patch is applied. Until such point in time when I'm notified the trouble is resolved, I will not be using the autopilot. Tesla charged several thousand dollars for this system.

Random breaking was prevalent with driving computer 2.5, which recently upgraded to 3.0. The "phantom breaking" is more general and is very dangerous. There have been locations where the vehicle behind me almost wrecked due to my car brakes slamming on out of the blue. I looked up the issue online and found the problem has been happening for years. My wife will not ride in my car now due to the fear of an experience when this phantom breaking accused while she was with me. I am using adaptive cruise less often and not using autopilot. The downside is that the car's efficiency is reduced when not using these "smart" features.

numerous incidents of phantom braking on open unobstructed highway, causing potential rear end collision. Reported to Tesla on several occasions. Currently on my 3rd MCU(media control unit). Service scheduled with Tesla but I am not optimistic since it has been a persistent issue since owning the car in 2017
