While traveling from San Diego, CA to Louisiana on the self-drive mode the car abruptly stopped in traffic 3 times (while this was at night there was no concern for an accident). On the return trip back home it did it 1 more time in the daylight hours, but this time there was an 18 wheeler behind me. We were doing the speed limit at the time, which was 75mph and it slammed on the brakes making me go from 75 mph to 60 in seconds. I was able to take control of the vehicle and get it back to highway speed before there was an accident.
2018 Tesla Model 3 driver assistance complaints
Page 8 of 10: complaints 191 to 220 of 253, newest first, as owners wrote them.
"PHANTOM BRAKING" when cruise control is on, usually when on the freeway. Sometimes it occurs next to other vehicles, sometimes there are no cars around. On a 600 mile trip it will often occur at least once and most of the time 2-3 times. If it was slippery, the sudden braking could cause loss of traction. If someone was too close behind me they could rear-end me. No one has inspected the issue. Has been occurring since I've owned the car. No warnings.
Everyday while I am driving on the highway, when the car is in cruise control, multiple times it decreases the speed drastically for no reason.
Since we purchased this car 3 years ago, when driving with the cruise control, it has in appropriately applied the brakes. This is a ongoing problem. This is a frequent occurrence (once or twice during 100 mile drives) mostly on 4 lane high ways. The most common situation where this happens is on a uphill rise in the highway and a overpass at the top of the hill. It can be a slight application of brake or a very strong application which is very dangerous with a large truck or close following car behind you. I only use cruise control to rest my foot on long rides and turn it off when approaching a over pass. There are other times it is turned on when a truck passes on the other lane or a car entering the high way from an entrance ramp that the white lines are worn out. We only use the cruise control with great care.
On several occasions while driving with autopilot on the car has suddenly and inexplicably braked HARD while at highway speed. Each time there was nothing in the road, no car, no obstruction, no anything, but it was as if the car saw something that wasn't there and jammed on the brakes. I quickly took back over and returned to highway speed. Luckily we were not in heavy traffic or I would have been concerned about being rear-ended by another vehicle. I don't do a lot of road trips with the car and have used autopilot less as a result, but I would guess it has happened 4-6 times since I have owned the vehicle. I just thought it was a glitch that they would work out but just saw reports of others still experiencing this issue so thought I should report it so you were aware of the breadth of the problem. The date below is a total guess as to the last occurrence.
the car tart to have sudden unintended acceleration at low speed after fully charge. The car will stop at the road Suddenly. leave car and back. The AC run for 1 min and shut down. I heard a sound which is from battery switch. 9/21, 11:15 am It happened again. I hear a sound and the car show alert. “”Pull over safely” — The autopilot system will slow down a lot passing a bride, even there is no car in the road.
The software on the car is and has always been updated to the latest standard. Driving on east and westbound on US 60 near Phoenix and Mesa AZ the car will emergency brake from time to time. This condition has continued for years off and on and is still happening as of this week. Generally speaking it appears to be caused by shadows from the overpasses and is far more prevalent at low sun angles that create significant shadows leading up to those overpasses.. I don't recall it happening after dark. On several occasions I have submitted "bug" reports via Tesla's online automated system.
Tesla FSD beta/ autopilot has frequent phantom braking. Sometimes for oncoming traffic in opposing lane or because of parked cars or even a shadow or nothing at all. It’s dangerous especially when it slams on the brakes so hard items in car will fly to the front. Could cause rear end collision or startle driver and cause them to react poorly. I have been doing bug reports and sending emails to Tesla FSD beta team since 11/2021 after each new update and it has never been resolved even remotely to an acceptable safe feeling product for use.
The car has been suddenly slowing from 70miles/hr to 50 miles/hr on the highway when on autopilot. I’ve been noticing this for about 6 months
I read in the news that you are investigating phantom braking in cars without radar. I want to make sure you are aware that this is also affecting cars with radar. Each software update makes it worse as they seem to use the radar less and less.
While using Autopilot adaptive cruise control at speeds of 50-70 mph, the car suddenly applies the brakes even though there is no car or other hazard anywhere near the car. This phantom braking has been happening since I bought the car in 2018. I imagine it's a software problem. I read recently that the federal safety agency is investigating a similar problem on 2021 and 2022 Tesla Model 3s, so wanted to let you know that this problem is also affecting my 2018 model. Also I read that there's speculation that the problem was as a result of a software update over the past year, but in my vehicle the phantom braking has occurred since 2018. The problem most recently happened last week.
The car breaks automatically when neighboring cars drive by during autopilot. I have a family of 4. This appears to happen when using autopilot almost every single time. It has gotten worse over the years. This car is becoming dangerous.
Car constantly phantom braking seemingly because of oncoming traffic safely in their own lane.
While driving to work, in 2021, I had experienced sudden deceleration and disengagement of the autopilot. It happened a few times. I have ignored it thinking it to be an electronic glitch. I did not know how to report to Tesla. But since I was sharing my data with them, I thought they will pick up some issue and alert me if there is really something malfunctioning. But I just found out that other customers has had similar issues and that I could report it to the federal safety agency, therefore I am reporting it albeit delayed.
My 2018 Tesla model 3 experiences “PHANTOM BRAKING” specifically and repeatedly traveling eastbound on the Loop 202 approaching 32nd street in Phoenix AZ. I have reported this issue to Tesla with no resolution.
As others have reported, please add my 2018 Model 3 to the list of reports of the vehicle having constant phantom breaking issues that Telsa needs to address. I'm glad you are conducting this investigation. Most times phantom breaking occurs I submit a "Bug Report" using the voice button in the car that sends car logs directly to Tesla so they will have records of these phantom breaking issues at the exact time and location my car experienced it. While it is random it also is very predicable at certain spots on highways I drive in the Bay Area. Namely 680 South in the HOV lane right before the Mission Blvd. exit. At least 90% of the time even I'm the only car in that stretch of road the car breaks hard for no reason. It is occurs so often in that section that I typically disconnect the Advanced Cruise Control in sections as well as other section of the Bay Area where phantom breaking consistently occurs. Two of my neighbors also have M3's and we have compared notes and we all typically see phantom breaking occur in similar areas in the Bay Area.
On several occasions, with Autopilot engaged my 2018 Tesla Model 3 has strongly applied the brakes while traveling at highway speeds, despite the fact that there were no obstacles up ahead. This has occurred throughout my ownership of the vehicle, and in each instance, it has been extremely unsettling. It required me taking manual control of the vehicle in order to return to highway speed. I do believe that on these occasions my safety and that of my passengers and other motorists has been at risk. It is worth noting that each time this has occurred there has been an overpass up ahead. I have hypothesized that the Autopilot interprets either the overpass or the shadow cast by the overpass as an obstruction. In my experience there is an apparent correlation here that is worth exploring. I was motived to report my experience after reading today's NY Times article (2/17/2022) about "phantom braking". The article indicates that you are "focusing on Tesla Model 3 compact sedans and Model Y hatchbacks that were made in 2021 and 2022 and sold in the United States." Based upon my experience, you may need to you broaden your inquiry to include other model years.
The contact owns a 2018 Tesla Model 3. The contact stated while driving at 60 MPH with the cruise control activated, the vehicle inadvertently decelerated to 40 MPH. There was no warning light illuminated. The accelerator pedal was depressed and the vehicle responded and accelerated as needed. The contact stated that the failure was intermittent. The vehicle was taken to the local dealer however, the mechanic was unable to determine the cause of the failure. The dealer also informed the contact that the failure was a known issue and that the manufacturer had been made aware of the issue. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 14,484.
The contact owns a 2018 Tesla Model 3. The contact stated that while driving at highway speeds with the vehicle in auto pilot mode, the vehicle would erroneously reduce speed and on occasions nearly come to a complete stop. On one occasion while driving approximately 70 MPH, the speed was suddenly reduced to 10 MPH. The cause of the failure was not determined. The manufacturer was notified of the failure but no assistance was offered. The local dealer was not contacted. The failure mileage was 5,000.
1. Phantom Breaking when on Adaptive Cruise Control. 2. Many times , unexpectedly there will sudden application of brakes, or slowing down of car when on highway and with speed in range of 55-65 mph. 3. Mostly this happens when big truck comes in front or passing thru a bridge. 4. Many times I am not able make any reason of this sudden brakes. 5. Many times due to sudden deacceleration , I have a car following in back, came very close , and honking.
On multiple occasions while my car was in Autopilot mode on highways and at highway speeds, I have experienced rapid braking (phantom braking) when there was no apparent reason for such. All of the phantom braking events have occurred on sunny days, usually around mid-day. Most often, the events have occurred when approaching a bridge or overpass. My supposition is that the system is mistaking dark shadows under bridges as obstacles that need to be avoided. As a result of the frequency of these events, I no longer use the system on sunny days.
I drive along the highway and all of a sudden while I'm in adaptive cruise control my car brakes suddenly for no reason.
When driving on autopilot on highways phantom breaking occurs for no reason. There are no warnings, the car just slams on the brakes. Elon Musk has state they were removing radars from cars to eliminate this issue and disabling it in cars with that hardware, but since my car have gone to all vision it is much worse. While following vehicles should always follow at a safe distance to prevent collisions, the reality is most drivers follow too closely and this could very easily result in a rear end collision. It could also trigger road rage from following drivers assuming the driver is doing a brake check on them. This has occurred numerous times over various software versions, but its much worse with the pure vision version of autopilot. Current software is 2021.44.30.5
While using Tesla autopilot on surface streets, the car will randomly brake. Additionally, it frequently thinks that green lights are red and will stop the car at an intersection which can cause an accident as other cars will not be stopping.
Was on highway using full self-driving feature when my car suddenly braked hard and in other instances I received a forward collision warning to take immediate action. These incidences (1/17/2022 & 2/6/2022) occurred when no cars were in front of me. I do not feel safe using this feature.
When I use auto pilot on freeways, the car will suddenly brake, when there are no vehicles or obstructions in front of me. The sudden reduction in speed is jarring, as I fear getting rear-ended. This "phantom breaking" has happened on numerous occasions, to the point that I do not use auto pilot when I have other passengers in the car.
Tesla introduced blind spot camera availability with the release of Version 11 software. When the driver switches lanes while in autopilot by engaging the turn signal stock at night, the built in turn signal led above the repeater camera blinds the camera by washing out and degrading the camera picture as the turn signal led turns on and off. This has been remedied in newer model year cars as shown in the following youtube video-- https://youtu.be/_BUPsjguqdY This is a safety hazard to vehicle occupants as well as the driver of the vehicle as the repeater camera is being blinded by the turn signal led.
Car randomly brakes very hard when using driver assistance systems. This has happened on wide open roads on clear days, multiple times.
I drive twice a week from Washington DC to Charlottesville, VA, a distance of 117 miles each way. 35 miles are on an interstate and 82 miles are on a divided 4-lane state road. Since I restarted this commute in September 2021 after Covid shutdowns and summer break, I have experienced recurring, frequent problems with the car's vehicle warning system, adaptive cruise control, and forward collision notification system. When I drive on the interstate (where there is currently a great deal of construction), the adaptive cruise control keeps automatically adjusting my speed when there is no speed limit change. So I might be traveling at 65 mph when my speed is suddenly lowered to 30 mph. There are no warnings, either visual or audio. The speed just changes. This is incredibly dangerous and requires me to be hyper-vigilant to avoid a rear end collision, or to turn off the cruise control system. When I travel on the state road, I receive frequent visual notifications of a collision risk ahead of me. I received four of them yesterday, and there was nothing in front of me at all. But sometimes, all automated systems disengage, a visual warning appears on my vehicle screen, and a loud klaxon sounds. This happened twice yesterday. It often occurs when I'm driving on a hilly stretch of road, when I'm ascending towards a crest in the roadway. It happens more at night than in daylight, but it happens without warning under a variety of conditions. The car also has an automatic lane change feature, which used to work reliably, but now seems more capricious, for no apparent reason. I engage the system, the screen shows it's safe to change lanes, the vehicle initiates the lane change, and then the car suddenly lurches back into the lane I'm leaving, saying the function isn't available. This has happened in all traffic conditions, from an empty highway to one with moderate traffic. I don't use the system when there's a lot of traffic.
