Multiple times, the vehicle braked on its own while traveling eastbound on the Interstate 8 freeway between Yuma, AZ & Gila Bend, AZ. This was when no other vehicle or obstruction was on the freeway within a mile of the vehicle. The braking was very jarring, and if another vehicle was behind us it could have easily caused a high speed rear-end collision.
2023 Tesla Model 3 driver assistance complaints
Page 5 of 8: complaints 101 to 130 of 198, newest first, as owners wrote them.
The Driver Assistance System fails. Specifically, the cruse control, parking assistance, blind spot monitor, display of other objects, lane identification, stop sign or traffic light recognition and other safety features fail repeatedly.
While on our first road trip in this vehicle, we engaged Adaptive Cruise Control (ACC). After about 30 minutes, the vehicle suddenly (within 1-2 seconds), and without warning, decelerated from 75 mph to under 50 mph. After re-engaging ACC, exactly the same thing happened again 5 minutes or so later. Thereafter, we did not use ACC, and the car ran fine. This was a safety hazard because if someone had been following us when these incidents happened, it could have resulted in a rear-end collision. We have not yet taken our vehicle to a service center. Since there was no resulting accident, we have not reported this to any authority. Clearly, however, our Tesla Model 3 has a safety problem.
While driving with cruse controll, auto pilot, or adaptive cruise control my vehicle brakes suddenly without warning and without any reason or danger. This has happened many times. Today on the I8 traveling from Yuma az to Surpirse AZ the car braked around 15-20 times with out reason. I held the tesla car symbol on the screen to report the problem.
While driving on a two lane highway I experience daily ghost braking incidents. While doing 75, in both cruise and autopilot mode, the car will slam on the brakes when approaching a semi in the right lane. Today it even swerved to the right without the semi moving out of its lane. I also experience panic braking if a car crosses the lanes in front of me even if it is 500m away and the crossing car even left the road before braking occurs.
When cruise control is engaged, the vehicle suddenly decelerates, (at times dropping speed by more than 20 mph in less than 2 seconds). This occurs as often as 5-10 times in a single 60mi trip, and occurs at least once per trip on this same route (divided highway, sometimes with hills, often with no other cars ahead of or around the vehicle, speed 60-70mph) These events are unsafe because unexpected braking is a hazard for following cars and my passengers. My job as a driver is to be as predictable as possible, but when I use the cruise control the car behaves unpredictability Problem reported to dealer, confirmed by remote diagnostic, and car was serviced but the problem got worse. There are no warning lamps or error messages displayed in conjunction with these sudden braking events. First appeared when the car reached 2000miles on odometer
When on a recent trip from Salt Lake City to Denver Via I 15 to hwy 6 and on I 70 When it was in cruse control and also auto pilot the car would on it's own brake. Some of the time it would brake very harshly others it would not be so violet ,but would certainly be some thing that could cause a very bad accident. The only solution Tesla service would offer was to go on a test drive to see it happen. This could take posably many miles, and then said they did not have a solution.
Vehicle suddenly brakes while in autopilot with no road obstructions. This has happened to me several times and I'm concerned that if someone is following me too close this may cause a collision.
The cruise control was set at 70 MPH. The car braked itself and tried to stop itself even though I had no cars or objects in front of me. I had to apply the accelerator to get it to out of stopping itself. It happened twice in a short amount of time on that morning. The car is available for inspection. This is a safety issue as it could have caused an accident if I had someone too close behind me while driving on freeway I-75. I have not had the car inspected as this just happened yesterday 09/22/2023 and today is 09/23/2023. There was no warning prior to this happening and no issues with the car. Again this happened on 09/22/2023 for the first time. Thank You.
Power steering stopped working when the car starts up, Cannot steer the wheel at all in PDNR. Basically cannot steer the car at all and it is not drivable.
Cruise control set to 82mph on interstate with no cars nearby. Car slams on brakes on multiple different cruise control sessions. Dangerous for other cars that could be driving behind me and could cause me to lose control of the vehicle.
I was driving on I-35 from Kansas City to Des Moines on 9-11-23, and three times the car experienced phantom braking (i.e. the car suddenly braked for no apparent reason) while the adaptive cruise control was activated. During these instances the car would suddenly brake and slow down and on one occasion I had to accelerate immediately to avoid possibly being rear ended. On all occasions there were no obstacles on the road or cars within 1/4 of a mile ahead of me.
While driving late at night at highway speeds (interstate Hwy), the car applied the brakes suddenly and without cause, with no cars in the proximity of my vehicle. The car was set in cruise control mode (adaptive.) It appeared that the vehicle may have picked up a reflection from the highway striping. This occurred two times during a single trip of approximately 200 miles.
On 09/08/2023 while the vehicle was engaged in Autopilot/Traffic Aware Cruise Control and at highway speeds, the vehicle suddenly braked with no visible / reasonable cue from the surroundings. Minutes later, it suddenly braked again suddenly and without any visible cause but with more force. After this, I stopped using this feature of the vehicle for the remainder of our trip. A similar event occurred around Apil 2023 and when I reported this to the Tesla Service Center they replaced both the right side and left side repeater cameras (faulty). The first incident of this nature occurred around a week after taking ownership in late October: Again at highway speeds, the vehicle suddenly and abruptly braked without cause. The Service Center was notified but they found no issue with the car. This type of behavior places myself and my family at risk of being rear ended with the abrupt nature of this kind of braking (sudden, abrupt and with no cause). It also places the vehicles that happen to be following me at risk with this sudden braking behavior - the braking is not gradual. After I reported the most recent incident, the service center did not find any faults with the hardware and said that "these behaviors are a limitation of software in the system."
The car does phantom braking on the highway when using cruise control. It is usually caused by a truck in the neighboring lane applying it's brakes, but not entering my lane.
1. When vehicle is on autopilot mode. Vehicle will all a sudden brake by itself with no reason as to why, no cars in front of me intermitly. Mostly happens when driving at highway speeds and when approaching a overpass. 2. Could be crash from the rear. 3. Have not notified Tesla. 4. No inspections have been performed 5. No warnings and no beeping either just brakes by itself intermitly.
The vehicle slowed down at a very rapid rate when in cruise control for no reason. There were no other vehicles or obstructions anywhere near the vehicle. This happened 3 times. I reported these events to Tesla and they said it was a known issue called ghosting and there was nothing to repair. A rapid deceleration of the vehicle for no reason and with no warning is a safety issue that should be addressed immediately. Iv'e used cruise control on many other vehicles and have never had a problem.
We were driving on cruise control on 7/24/23 between the hours of 6AM - 8AM on a completely open highway with no cars near and no objects in the road. Our car braked on its own when we were driving 74-77MPH bringing the car to an almost complete stop. The same thing occurred on 7/22/23 between the hours of 9AM - 2PM. It was extremely scary and an obvious malfunction/ defect of the car. We both have back pain now from the sudden stop.
The car makes unintended braking when there is no vehicle in front. The car made a sudden brake from 75 mph to near 0 mph such that the driver felt that the vehicle almost flipped.
I was on a road trip in South Dakota through I-90 and the vehicle stopped in middle of the road caused by phantom braking while running by its autopilot (7 times total). In multiple instances, there were vehicles not far behind. This is really scary as in any moment we could have been in a fatal accident on the 80mph road. Tesla needs to fix this ASAP. Not acceptable at all from a vehicle that costs this much.
While driving westbound on US Rt 50 in Nevada with AutoSteer Beta engaged, car repeatedly decelerated rapidly with no audible or visual warning presented. This "phantom braking" could easily put vehicles traveling behind mine at risk of a collision. I have been able to reliable reproduce this in certain conditions - when a mirage is present on the roadway ahead and there are no cars immediately in front, the visual object detection system is apparently thrown off by the refraction of light and incorrectly detects cars, pedestrians, or motorcycles where none exist. As I see it, there are two major problems in play here - one is that the camera-based object detection system is easily confused by the presence of mirages on the road surface ahead and there are no other sensors in other portions of the EM spectrum (IR LIDAR or RADAR) to confirm the presence of visually detected objects. The second is the lack of audible driver warning before deceleration takes place. The only indication that occurs is the energy use indicator (a thin line at the top left of the screen) shows energy use transition to regeneration. Together, these constitute a serious safety hazard for anyone operating these vehicles and those following behind them.
While using cruise control on a highway traveling between 65 and 75 MPH the brakes slammed on when there was absolutely no traffic in front of or beside us, no overhead obstructions, no upcoming corners, nothing at all but straight road ahead. If anyone had been behind us we could easily have been rear-ended. The car had only 1500 miles on it the first time it happened. There were 4 such events in our short 400 mile road trip. Took it directly to Tesla service and have been told there is nothing wrong with the car!
I was driving and the power steering stopped functioning. The car had just over 1000 miles and both the lane departure avoidance and steering assistance cut out. Restarting the start would bring it back on temporarily but it would cut out again after a minute or two.
Turn signals shut off after three blinks with no lane change or steering wheel movement. Lane departure / assistance fails to function. Blind spot monitor / alert fails to function. Adaptive cruise control / braking fail to function. Problem first reported to Tesla on 7/6/2023. Telsa installed software update to resolve remotely. Problem recurred 8/6/2023, towed to Tesla 8/7, Tesla replaced side camera assembly. Problem recurred 8/132023, software update installed & resolved. Problem recurred 8/19/2023. Vehicle to be towed to Tesla for further diagnosis / repair.
The vehicle will randomly brake when cruise control is being used. No obstructions, good weather conditions and flat road.
Car accelerated forward unexpectedly while making a turn and hit a telephone pole. Brakes did not engage nor did the forward collision warning sound or engage. Was manually driving. Car is non-driveable and repairs from Tesla are backlogged so we waiting 8+ weeks to get our car back.
I enabled the tesla adapter cruise control during my trip in interstate 15. All of sudden, the car stopped to a slow speed for no reason. There was nothing in front of my car at that time. I was able to step on the brake to disable the cruise control and step on the accelerate pedal to resume the speed. Luckily there was no vehicle behind us, otherwise it might have been a rear end collision.
During my first highway trip from Dallas to my home in Alpine, TX, I experienced numerous instances where the car would suddenly decelerate as if I had applied the brakes. At first I thought it was because there was a lot of road glare because I was driving late in the day into the west sun, but the next day it happened early in the morning when the sun was behind me and the road was straight, relatively clean with clear markings. The ultimate instance was when I was driving on a newly reopened dark asphalt road with new markings, straight, no glare, sun behind me. Clearly there is a problem.
While traveling on a busy interstate highway, my Tesla 3 presented four errors on the control screen: Automatic Emergency Braking disabled, Power reduced, Vehicle shutting down and Unable to drive. The left hand side of the screen flashed red and instructed me to pull over safely. The car was immediately slowing down, and as I was in heavy traffic, I was unable to pull over to the shoulder safely. I turned on my hazard lights and performed a soft reset of the car - which caused my hazard lights to turn off, all while cars were honking and whizzing around me. After the car reset, I was able to drive a short distance, with enough speed, to cross several lanes of traffic and come to a stop on the shoulder emergency lane of an exit ramp. The car is only 6 months old, with 4000 miles, but had to be towed to the Tesla service center. The problem has been diagnosed as a problem with the rear drive unit inverter and will be replaced under warranty. While I appreciate the resolution and that it will be fixed, it could have been a very serious situation and caused an accident. Thankfully, I was able to get to safety and wait to be towed.
I was driving on a rural, two-lane highway with no other cars around and with cruise control engaged. Without warning, the car decelerated suddenly and rapidly from about 60 MPH and continued to decelerate until I pressed on the accelerator pedal (at about 40 to 45 MPH) to stop the deceleration. It happened at least 5 times during a drive from Spring Grove, IL to Champaign, IL on July 7, 2023, between 10:30 AM and 2:00 PM. If there had been a car following close behind me it would have been very dangerous. I had the Basic Autopilot engaged with Traffic-Aware Cruise Control (but not Autosteer). Weather conditions were bright sunlight with a few clouds. The problem has occurred several times (at least 4 times) since then. The problem has not been reproduced or confirmed by a dealer or independent service center. I have not had the vehicle inspected by anyone. There were no warning lamps, messages, or other symptoms of the problem prior to the failures.
