Vehicle Speed Control Problems of Tesla Model S - part 2

My instrument cluster is delaminating in my Tesla Model S. When I took it to the service center for the recall service the service center stated that the main screen was also delaminating. Service tech told me that the instrument cluster (and main screen) would eventually fail because of the delamination. I have had the car for less than 8 years. Both the instrument cluster and the center screen have a lot to do with safe operation of the vehicle so I believe they should be replaced for free under recall or at least have a much cheaper upgrade option. It is extremely rare for any car to have a common problem of the intstument cluster delaminating and this should be a recall since it is an ongoing, common issue. This is a problem telsa knows about and hasn't done anything to remedy for a reasonable price. They want $1,750 for the upgrade of the instrument cluster and the main center screen. I bought the car when they were talking about self driving features that are not even possible for this car so I was mislead on that too. Here is other documentation of this issue. . Read more...

The contact owns a 2015 Tesla Model S. The contact stated that while driving at approximately 65 mph, the vehicle inadvertently swerved in and out of the lane and accelerated unintendedly for approximately 8 to 10 seconds and then performed as designed. No warning lights were illuminated. The dealer was notified of the failure and an appointment was scheduled. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and the contact was informed that no failure was detected and informed that a report would be filed. The failure mileage was approximately 37,000.

While driving reduced power light came on. On highway speed reduced to a crawl.

The car was on enhanced auto pilot and was moving at about 50 mph, the traffic in front of me slowed down. The car failed to give an alert, it failed to slow down and stop. I applied the breaks, but by then the car crashed into the pick-up truck in front of me. The car came to a complete stop after the crash and the computer system in the car completely shut down. The car had to be towed to the garage. My safety and the safety of the driver in front of me were at risk due to malfunction of the enhanced auto pilot system we immediately filed a service ticket with Tesla and upon repeated requests we were told that car could not be inspected and the breaks or auto pilot system could not be tested as the car was not drivable. Police and car insurance company were notified. Tesla was able to provide us with a edr there were no warning signs or messages prior to the malfunction.

3 separate times the right pillar camera and 2 times for all cameras: the car's computer lost contact with the cameras and could not reconnect. In 2023, Tesla changed from radar to camera sensing technology. All driving functions relating to car positioning and cruise/speed control were lost at those times. Twice the car was under cruise control so the car interpreted this as 0 mph and initiated emergency braking from 75 mph on an interstate highway. I was able to avoid the following cars hitting me only by instantly accelerating back to posted speed. Tesla has been very difficult to convince that this is a problem. They say that remote diagnosis is inconclusive. Since they go for "at home" service first, 3 separate service times were cancelled by them, and they will not allow a service appointment at their shop for further diagnosis. Warnings came up on the instrument display, but only for 10 or 15 seconds, in words too small to read. Since I am trying to maintain control of the vehicle, I cannot stare at the screen to try and memorize, or find my phone to try and take a picture. This vehicle does not allow the owner to look at the error/trouble logs, so exact times and dates are elusive. Tesla refuses to start investigating until the exact warning, date, and times are advised. Dates are known, approximate times and driving conditions are known but aren't good enough.

On March 19, 2023, I put my Tesla in drive and it went into reverse . When I tried to brake the speed accelerated. We were unable to stop the vehicle, while driving in reverse the car hit two mailboxes and two ceramic flower pots. It has been over 6 weeks and Tesla will not return my calls or messages. My insurance company looked at the body of the vehicle for a repair estimate. Nothing indicated that there was a problem prior to the incident.

In 2014, I ordered this Model S p85d, received it on 12/20/2014, I also purchased a 4-year extended service plan. Starting from March 2017, it started to encounter random yet serious problems. The car would randomly produce critical errors, displaying several types of error messages, while losing most of its driving power; the driver would have to perform emergency pullovers onto the road shoulder, if available, before the power rapidly reduce to zero. Then the driver need to restart the main computer (sometimes several times), to reset the error messages. Only after that, the car became drive-able again. I wrote an email to servicehelpna@Tesla. Com on 03/23/2017 describing the problem, since then, this became a chronic issue; service centers in virginia, maryland, and san juan pr have performed numerous attempts on this problem, none of them was able to fix it. According to my records, for this issue, the car has been in the shop for more than 10 times, and more than a dozen components have been replaced. The total time it has been out of service is more than 380 days. I now consider it "unfixable" by Tesla. This kind of problem have created many dangerous situations when it occurred on the road, especially when the driver doesn't know how to handle it, doesn't pull over on the shoulder quickly, or there's no safe place to pull over.

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.

The traffic-aware cruise control has been braking unexpectedly and for no valid reason. The most recent example was when we were driving along us hwy 24 between wilkerson pass and fairplay, CO. The car suddenly braked even though there was no hazard. This has been happening regularly on this drive, in both directions, multiple times per drive. When this happens, the road is generally straight, with little, if any, elevation change. This is a safety issue because if this happens when a car is driving closely behind us, the unexpected braking could result in a rear-end collision. I have not reported this to Tesla because I understand this is a widespread issue that many people encounter, so I believe Tesla is fully aware of the issue. This problem seems to have gotten significantly worse after Tesla deactivated radar in the vehicle (without my consent). My understanding is that they are now using only cameras to manage traffic aware cruise control. Regardless of the reason, this issue has been happening with much greater frequency since around December, 2022 or January, 2023.

When driving with autopilot engaged, the vehicle sometimes gives alerts even when there is no vehicle or obstacle in its path. Immediately once the driver takes control, the autopilot does not disengage but continue as usual. The autopilot suddenly brakes or slows down even when there is no obstacle on a freeway.

On freeway in traffic, autopilot is enabled. Vehicle is running perfectly fine in start stop traffic slowing down and speeding up as needed. Traffic starts to clear up, and as vehicle speeds up, there is a sudden slowdown again. Instead of braking/slowing down, autopilot turns off without an additional audible alarm (just the standard sound for turning off autopilot), instead the forward collision warning alert goes off. Able to brake in time to prevent accident.

While driving out 2018 Model S, it will brake hard while in adaptive cruise control of full self-driving mode for no reason. This happens frequently, whether driving on the highway or on city roads. It is terribly unsafe. I'm afraid eventually someone following too close will hit me.

Instrument display is frozen at 0mph at 7:57am even while driving. Uploaded photo was taken at 9:19am as indicated on time stamp and on larger display at center of vehicle.

Driving down an interstate at the speed limit, with light traffic. No cars immediately or in ahead of me. The car put on the brakes, or what is commonly referred to as "phantom braking" as I understand it. It has done this on prior occasions and I am familiar with it. It generally seems to be triggered by inconsistent pavement coloring or shadows. The car rapidly braked until I took over (I was using "navigate on autopilot" which was managing the speed and lane-keeping). There were no injuries or dangerous situation created during this event, besides being quite abrupt and startling. There are no known failures or issues in my vehicle that would have been likely to contribute. This occurred on Nov 24 in the late afternoon, driving westward. Weather was overcast.

Apparent software issue with adaptive cruise control causing unexpected hard braking at highway speeds. Random hard braking occurs on open road when road is clear, flat, and no other vehicles nearby. Narrowly avoided being 'rear-ended' during several occurrences by car behind. I drove the car this week on a two day road trip from palm springs to santa fe and this issue must have occurred 18-20 times during the 750 mile trip. I also tried using difference settings and nothing seemed to eliminate the issue.

The vehicle went into "reduced power" (turtle mode) error. Which reduced the power and the ability to accelerate out of an intersection and away from incoming traffic. I followed the recommendations of powering the vehicle off. It would correct itself then randomly does the same thing. This is safety issue and needs to be resolved before someone gets into a major accident which will result in great bodily injury or death.

Car repeatedly, randomly slams in brakes while cruise control engaged for no apparent reason. Not speeding, no other cars or blockages around, open highway on a bright, clear day.

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.

We took our first major road trip in our new 2022 Tesla Model S on Friday 10/14, leaving at 10:00 am for a 9 hour trip. During the trip the car experienced multiple severe incidents of the car braking hard while at highway speeds and two of the incidents almost caused an accident. The car drops 10 to 15 mph instantly for no reason. We drove the car home on Monday 10/17 without aeb, auto steer, fsd beta, emergency lane departure avoidance and obstacle-aware acceleration and used tacc occasionally and still had the issue but wasn't as severe. Even on the day we purchased the car (sept 30) and drove it home (a short drive on highway 95) we had a similar incident but it was so new we weren't sure if it was us or the car but now we know it is a fault of the car and creates a very dangerous driving situation which could result in an accident or death to a passenger in our car or in the car behind us when our car decides to slam on the brakes for no apparent reason. There were no warning lamps, messages or symptoms of the problem prior to the failure. We turned in a service request to Tesla and their response was to drive the car and have it happen again and create a bug report. So basically Tesla is asking us to put our lives on the line to help them diagnose the problem because they don't want to take the time to review the diagnostic data that is readily available to them. In our opinion, this is a very serious and dangerous problem and the car needs to be taken off the road until Tesla resolves the problem.

The vehicle intermittently brakes for no reason with the cruise control enabled. This is going to cause an accident.

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 ?.

The car requires swiping the touchscreen to place it in drive or reverse. The touchscreen does not always register the intended change of direction, leading to unexpected, unsafe motion of the car. The area of the touchscreen that one must swipe is also often occluded by the steering yoke. This has happened multiple times, where the lack of strong enough feedback (or a mechanism that allows for less error-prone input) as to d vs r allows for an unsafe movement in the opposite direction of what was intended. In one case, there was traffic approaching, and the car ended up further in the path of that traffic. In another case the car should provide instantaneous tactile, visual, and/or audio output to clearly indicate that the car has shifted from d->r or r->d. A mechanical stalk or button, as was present in previous model years, would certainly be adequate.

While driving with traffic aware cruise control engaged and set at 55 mph the car did a hard break to an almost complete stop in the middle of the lane for no apparent reason. This occurred at least two times and both times there was no traffic in front of me. The road was a two lane highway. There was oncoming traffic and cars behind me but no cars in front of me. The breaking was so hard on both occasions and it startled me and caused me to veer off the road in the first instance . The car behind me had to break suddenly as well. After the second occurrence I disengaged the tacc as it seemed to be sensing the oncoming traffic.

On 4 Aug 2022, at 10:24am (cst), while traveling northbound on hwy 287 just south of henrietta, texas with the Tesla autopilot speed set at 80mph with a posted speed limit of 75mph, the car was in the left lane of a two-lane, high-speed highway, when the car suddenly and unexpectedly slammed on the brakes, gave a "take control immediately" warning and rapidly shifted its lane position, almost causing a wreck with the car behind me. There were no vehicles beside me and nothing to the front or sides to cause concern or indicate that there was any reason for the sudden and abrupt braking maneuver.

Instrument cluster not powering on or crashes/glitches while operating the vehicle. This makes the vehicle unsafe to drive while auto pilot is engaged because the auto pilot system stops operating which could lead to a serious accident. The vehicle speedometer and all other instrument cluster warning systems are unavailable because the screen is off/not working. Tesla has performed a remote diagnostic and claims no issues are identified. They then proceed to upsell me the new infotainment system that will rectify this problem for $3,000 dollars.

Cpu compatibility to existing os and memory system causing multiple failures during driving with: 1. Instrument cluster reset or reboot (temporarily disables all controls related to buttons/knobs on steering wheel and possibly other safety functions), 2. Main nav/computer screen reset or reboot (temporarily disables all controls), 3. Auto braking activation (cannot be disabled by user) enabled at dangerous and unpredictable times of city traffic, 4. Backup camera picture not updating/frozen during backing uo vehicle, creating illusion a. Not moving when in reverse while driving, b. Not showing objects that may be directly behind vehicle when in reverse manufacturer (Tesla) service ticket opened and closed as “resolved with memory reset” without follow-up if problems still occur.

-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 -.

I just completed a round trip from minneapolis to oregon. During cruise control, the vehicle frequently suddenly braked at highway speeds for no apparent reason. This was extremely dangerous a few times. I have put in a service request with Tesla.

I have used the self driving feature of my 2022 Tesla Model S on several highway trips, most recently a round trip between seattle and palm springs. The following problems with the Tesla self driving feature were noted. (my car has only the basic self driving feature, not the full self driving upgrade) 1. Random “phantom braking” where the car, without apparent reason, suddenly braked. 2. On several occasions the car abruptly swerved off toward an off ramp. I think this occurred when the white line marking the side of the road was interrupted by the off ramp where there was no painted line. 3. On several occasions when the turn signal was activated in order to change lines the car started to move over into the adjacent lane but abruptly swerved back to the original lane. I was able to maintain control but it was a frightening event. Due to the unpredictable nature of these events I greatly reduced my use of the fsd feature.

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.

The contact owns a 2018 Tesla Model S. The contact stated that while driving down an inclined driveway the vehicle suddenly experienced unintended acceleration causing the driver to lose control of the steering and crash into the nearby RV garage. During the incident the airbag deployed and the driver sustained injuries to both knees and left hand. No police report was taken. The cause of the failure was not determined. The contact indicated that the failure had previously occurred in 2018. The manufacturer and local dealer were not notified of the incident. The failure mileage was 38,000.

Phantom braking: I was driving northbound on the I-5 highway south of sacramento, California using cruise control and traveling at the 70 mph speed limit on September 14, 2022. At approximately 2:50 p. M. , I moved from the right lane into the left lane by using the turn signal to execute the lane change. Once in the left lane, the car immediately began violently applying the brakes. There was a car behind me that appeared as if it was going to rear end me. I pressed on the accelerator pedal which allowed me to regain control over the vehicle and avoid being hit by the vehicle behind me. The weather was clear and visibility was excellent. There was no apparent reason for the emergency braking system to become operative.

Bubbles first appeared in the dashboard / instrument control panel display on the driver side on 3/25. The bubbles have been moving around over time and at some points while I've been driving (unable to take a photo), have travelled to the speedometer blocking my visibility of current speed.

Brake pedal switch is malfunctioning causing the brake lights to turn on by itself when driving 60mph+ when I am pressing only the gas pedal and then it’s causing the engine to shutoff or power reduced due to “both pedals pressed” alert in the system. This can cause an accident 1st for sending the wrong brake light signal for the drivers behind me and 2nd to shut off engine when driving at high speeds. If this happens when driving uphill can cause the car to slow abruptly and even start going backwards due to engine shut off. Also I have concern that I had to reverse press (pull back) the brake pedal with my left foot in the middle of the highway to get rid of the alert while I was pressing the gas pedal with my right foot and then to regain gas power to continue to speed. Again, this is dangerous action that can cause an accident.
