general problems of the 2017 Tesla Model S

Software 2025. 14. 1, full self driving 12. 6. 4 (fsd). Vehicle when using fsd continuously slows to 10 mph below the speed limit. You can manually press the accelerator to speed up but fsd will not brake when doing so and warns you of the same. After a minute of being back at the speed limit, fsd again slows down. Repeat this process constantly. Very dangerous.

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.

Approaching my garage door as it was opening when the car suddenly accelerated smashing through the garage door, through the back wall of the garage, through the laundry room and finally stopped in the main bedroom with the front wheels off the ground as the car rested on top of the washing machine.

Since full self driving, beta has been turned on my car no longer slows down when I reduce the speed or when it encounters a lower speed limit sign, which it will read the speed limit. Prior to this when I decrease the speed or it noticed a decrease speed limit sign. It would use regenerative braking to slow the vehicle down. Now it’ just coasts , and actually sometimes maintains power at a high speed. There are times from going from a 60 and then to a 40 and then to a 30 mile an hour speed zone where it will continue to travel at 50+ miles an hour through the entire speed zone without slowing down which it did not do before fsd beta was active. I have to disengage the full self driving in order to get the car to slow down.

This alert is about "phantom braking", which is well known to Tesla owners, and the subject of much online discussion among owners who seem to all experience this and are furious that it continues to exist. Here's what happens, very, very often yet: with adaptive cruise control engaged (with or without "autopilot", ie 'autosteer' also engaged), the brakes are applied suddenly without any need for braking (no objects in the way of travel, etc). We just completed a trip on I-94 from billings/red lodge, montana across north dakota, where phantom braking was experienced probably 50 times, with no other vehicles ahead of us, and on perfectly dry pavement, etc. There had also been very dangerous icy conditions (lots of even "skating rink ice") on the stretch of I-94 in montana, from billings into north dakota. Had the phantom braking occurred on one of the sporadic ice patches further east, it could have easily caused a serious accident, not just been a scary nuisance. In situations with heavy traffic, phantom braking could easily result in rear-end collisions by cars that may be following too close to react before we, the Tesla drivers, override the phantom braking by hitting the accelerator--even that simple maneuver cannot be executed before the car has suddenly decelerated 10-20 mph or more. Some of the phantom braking seems to have been somewhat corrected where we'd first encountered it, on I-394 west of dntn minneapolis--it doesn't happen as often now as it did a few years ago. There we'd suspected it may have been triggered by the shadows cast on the pavement ahead of us by overhead bridges. But this rash of events across north dakota this week brought our worst memories and fears back with a vengeance--and with zero theories that could explain it. On a recent online discussion about this issue, there were several pleas for Tesla to give us a "dumb cruise control" option till this gets fixed. Please help foster solutions to this difficult situation! thank you.

This is atesla Model S electric car. The battery was 80% charged at the time of the incident. Under normal driving at a speed of around 40 mph in a city road road, suddenly the car lost power. The steering wheel locked and I had no control over the car. Display screen in the instrument panel and the large central tocuh screen display blacked out. A few seconds later, the car control returned and I was able to safely drive the car. But, the momentary loss of control is dangerous and scary.

The issue occurred twice over the period of the past two months, both times I was driving on highway with Tesla autopilot enabled ( it is adaptive cruise control), for no apparent reason the car hit the brakes, all vehicles driving behind me had to hit brakes or change lanes to avoid collision. Both times I created service request with Tesla and got no clear answer to why its happening, first time I was told it is because the exit on map was about couple miles from car location so car had to hit brake hard and change lane to make it to exit but car never tried to change lane, it just did hard braking. 2nd time I was told it happened due to wheel alignment not being accurate. After wheel alignment was done I reached out to Tesla again but so far they can not confirm or deny if Tesla autopilot is safe for me to drive. I was told to use autopilot at my own discretion. Are car manufactures allowed to sell hardware or software without taking responsibility for its safety ?.

-I think there is known problem with the Tesla. It autoaccelrates o behaves like someone is taking ove the control fo the car - the inital problem happend on June 24th 2022. I was in the parking lot of my work when it felt like I had lost control of the car to hit 2 parked cars. It cost severe damage to front of the car. Car was in the workshop for 4 months. This was completely unanticipated. I have hisotry of driving in us for over 20 years on major freeways before this without a single accident may have developed muscle memory( reflexes by repeated actions) in controlling the car. I was not distracted at the time. Of note however my car had rear damages from being rear ended 10 days prior but Tesla authroized dealer had said it was drivable. The car was not in auto pilot mode - Tesla didnt give me any explanation and the repair workshop generalized saying it's usually driver's fault - since the return from the repair I have 2 auto accelarations driving in the low speed zone. I had to break immediately to control it. Each time it felt like somthing remotely did this. There hasnt been recurrent damage. --the car was inspected by the Tesla authorized workshop couple of times and they claim nothing is wrong. -there have been no warning except on 04/15/2023 when it happened smewhere between 1. 34 to 1. 36 I thught I heard sort of noise/ quick warning. Again, each time it happens it feels like car is trying to do its own thing ( even when it's not in auto pilot mode)or someone is remotely doing it. Further info on my car: it was purchased in 2020 as a used from Tesla. This problem of auto accleartion or loss of control feeling did not start until car was rear ended in June 2022. I have security footage from the parking lot on how the car behaved in June of 2022 -.

Vehicle automatically and unexpectedly applies brakes when using cruise control when no other cars are in proximity or approaching. Sometimes braking is light but other times it is a jolt that is extremely starling. Often happens multiple times within minutes. Unpredictable when it will occur. I have taken the vehicle to Tesla 3 times and they say that they know about the problem but their autopilot is still in beta and are not actively working on a fix. On 4/28/2022, while on a trip, there were 5 incidents between 9:51am and 1:43pm.

On numerous occasions the car, while on cruise control will suddenly, and for no reason brake. Sometimes very hard. The latest was today at 1336 mst.

Autopilot has failed many times. Car almost crashed. Took it to dealer for repair but they didn't fix the problem after spending $100,000, the autopilot should work as designed.

For many months, my Tesla's computer would reboot or just shut down while I was driving. That would stop the defroster, the ability to back up, and multiple driving issue. Tesla suuggestec that I replace the chip and the screen, I paid$2500. They refuse to pay for it despite a recall on the specific issue. It is well documented with tesls.

The defective mcu went down and what is not being properly reported, especially in this pandemic world we now live in, is that besides the entertainment, the air conditioning (and viral hepa filter), the suspension height, the steering and acceleration properties, nearly everything is no longer accessible when the mcu fails because to the driver, these things can only be accessed and manipulated through the center console, which is in permanent shut down mode. Look, I perform fmea analysis for a living. This is a single point failure being caused by the poor decision to select an mcu chip that has a limited number of data writes to the memory, and that cannot be cleared out by any system designed into the car. Mine just failed last week and my car only has 30,000 miles on it. Tesla claims that they only warranty the entertainment system for 25,000 miles. The problem is that they've integrated the mcu and emmu as the single source of operations for all other vital systems in the vehicle. This is completely insane and is without a doubt a safety issue, as it was 90 degrees the day my mcu failed and dangerously hot inside my car, even with all windows down, which only got worse because there is so much thermal loads created by the battery, normally protected by the overheat sensors & fans, that are now not operating properly thanks to the mcu failure. It also important that you understand the most of the need to write to the finite mcu & emmu memory is caused by Tesla during their frequent software updates. Mine is a p100d ludicrous + and cost well over $100,000 when new. Tell me what other manufacture would be allowed to get away with designing a single point of failure that effects nearly every system including safety features, and then say its only covered for less then the time they know the first failure will occur. Criminals and make them accountable now please.

There are challenges with the mcu1 and its integration with fsd hardware #3. This manifests as freezes on the central and drivers displays until the cars mcu does a full restart(speedometer is not affected). This restart can take as little as 5min or can stay off for the drive until manually force reboot initiated. During the freeze I experience loss of passenger airbag(warning comes on, I cant tell if other airbags are affected). The climate control system turns off no a/c or heat is available. Sometimes auto pilot is affected, so I would assume emergency braking is affected because its the same system as auto pilot. The odometer is does not record miles if this happens while driving. No back up camera is available. These issues have increased since I had the hw3 upgrade here is a website that talks about this issue https://Tesla-info. Com/blog/Tesla-mcu1-emmc-failure. Php https://teslamotorsclub. Com/tmc/threads/joe-rogan-vs-mcu1-hw3. 203776/.

I experienced the "phantom braking" phenomenon while driving on freeways. It has happened 3 or 4 times in the last year or so. I did not see any obvious reason for the car to have slowed down dramatically because there wasn't a car in front of me at such instances. It occurred while autopilot was engaged. It has happened on different freeways (I-680, I-880), traversing in different directions and at different times of the day.

This is a complaint about the Tesla autopilot. Please note that the VIN of a random Tesla Model S has been used to enable me to file this complaint. Here is a freshly uploaded youtube video of some kids fooling around with autopilot and putting many lives at risk. . Read more...

While attempting to park the car in a parking space the car accelerated on it's own and crashed over a small concrete retaining wall and crashed into another vehicle. My car and the car that was struck were totaled.

The contact owns a 2017 Tesla Model S. While pulling in the driveway at approximately 5 mph, the contact attempted to step on the brake pedal to slow down the vehicle. However, the vehicle accelerated through the garage and crashed into the house. There was no warning indicator illuminated. The air bags did not deploy. A police report was not filed. The contact sustained minor injuries that did not require medical attention. The contact stated that the vehicle would need to be towed. The contact called Tesla at 858-558-1555 (located at 4545 la jolla village dr, suite d17, san diego, CA 92122) and was referred to the manufacturer. The manufacturer was made aware of the failure and provided a case number. The vehicle was not diagnosed or repaired. The failure mileage was 21,859. The consumer stated she did receive medical attention for this accident.

2017 Tesla Model S started to accelerate on its own over 100 mph, when traveling on highway around 70 mph, without autopilot engaged. As soon as it started to accelerate, the car took control over the steering wheel and drove into the guardrail on the left of the lane, then quickly steered to the right lanes and steered to the left again. Slammed on the brake but did not work at all, and steering wheel did not respond. The car completely took control over traveling over 100 mph going zig-zag on three lane highway, finally came to a stop after hitting number of trees in the woods on the right side of the highway. The car is completely totaled.

Our Tesla has had two incidents in the last three months of uncontrollable acceleration. . . . Once slowly going into a parking place and once backing out of our garage. The first one resulted in a couple of cracked ribs (with seatbelt on) and $18,000 in damage. The second incident: the Tesla, when backing up went totally out of control by accelerating and it barreled across the street and knocking down a tree before coming to a stop. The Tesla is now in the repair shop with extensive damage to the rear of the car. Not sure yet of the dollar amount. I feel this is a serious defect in the Tesla Model S.

On October 18th, my Tesla was a minor fender bender . I was on auto pilot and going on a < 3 mph speed before the exit ramp. Another car was stationed in front of me and autopilot did not realize the car came in front of me and hit the other car. Though the damages are minimal & the other person waived his right to claim insurance . I wanted to understand the reason and the root cause of the current accident so that I can be confident to use the auto pilot going forward. Hence I filed a complaint with the customer support. After 4 weeks of investigation and repeated nudging from my side to expedite the investigation, I was told that the car was in auto pilot mode, and the car did not realize the other car in front until the accident occurred and the car did apply brakes after the incident. I also requested for the investigative logs and notes for my analysis but the request was rejected by the customer support.

Stopped at a busy city street intersection for around 2 minutes waiting for the green light. My car was second car from the intersection on a slight up slope. Obviously the brake was fully engaged but my car suddenly creeps up slope and gently bumps into the car in the front. This impact pushes the other car forward and my car rolls back. The forward collision alarm went off but I could do little to stop the car other than try and press on the brake even harder. The car again rolls up again and gently bumps the other car again. Again the collision warning went off but I felt I had no control over the car. I could finally get the control back after that. Luckily there were no pedestrians and cross traffic had already stopped. Please note that there was little or no damage to either car. The car seemed to have a mind of it's own! there was little chance of driver error in this case as I was just waiting for the green light and there was no panic situation for a mistaken accelerator press. I could not get access to the car logs as Tesla policy wouldn't allow it. Please note that no self-driving software was installed and creep mode was off as it always is.

The car failed to come out of the enhanced autopilot mode, even after pressing the brake pedals, and went straight through a red light, causing a collision resulting in total loss of both vehicles. I believe the 'self driving mode', or the enhanced autopilot mode was defective. We would like to get the vehicle data pertaining to events just before the crash, but Tesla would not give it without a court order. Even before this incident I had noticed that enhanced autopilot mode made dangerous moves on highway. At one instance, I was driving in the rightmost lane (in the enhanced autopilot mode), and a driver trying to merge in the highway was not willing to slow down, but neither did the Tesla, and I had to brake to avoid the collision. The autopilot did not detect the other car that was rapidly closing in to the Tesla.

The contact owns a 2017 Tesla s75. While the vehicle was in autopilot mode, it independently veered to the left to make a lane change. Additionally, while the vehicle was at a traffic light, it independently accelerated, made a sharp left turn, and drove into vegetation on the off ramp of a freeway. There were no injuries and a police report was not filed. Tesla of santa barbara (400 hitchcock way, santa barbara, CA 93105, (805) 770-6090) was contacted and the vehicle owner was informed to have the vehicle repaired. Afterwards, a diagnostic test would be performed. The contact stated that the failure recurred three times. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 3,000.
