general problems of the 2023 Tesla Model 3 - part 2

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!.

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.

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 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.

The adas regularly brakes suddenly for no apparent reason. There does not seem to be a consistent reason. Yesterday, during a 90 mile drive eb on the interstate in the afternoon it braked (scaring us) suddenly so often that it made cruise control more of a hazard than a help. This morning between 9-11 am, westbound on the same interstate it braked suddenly 20-30 times. This sudden braking is dangerous as unexpected behavior could cause an accident with any vehicle behind us.

The contact owns a 2023 Tesla Model 3. The contact stated that while parking, the vehicle suddenly accelerated, jumped the curb, and crashed into a building. There were no warning lights illuminated. The driver noticed smoke coming from the vehicle. The passenger's front seat occupant sustained injuries to her hand. The passenger rear seat occupant sustained injuries to her neck, and medical attention was provided. The air bags deployed. There were no reported fire. A police report was filed. A person in the building sustained unknown injuries, the vehicle was towed to a tow lot. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 3,000. The vehicle was deemed a total loss by the insurance company.

While traveling on the interstate using cruise control, my vehicle abruptly started to break which caused the vehicle behind me to brake as well. I did not touch the brake, accelerator, or the cruise control itself during this incident. And there were no cars in front of me or to the right of my position (I was in the far left lane).

While I was driving along a freeway using autopilot cruise control, the car suddenly slammed its brakes even if there was no cars in front of us. I thought it was just a fluke but it happened at least twice if not thrice during that trip. There was at least an approximate of 3 miles gap between us and the car in front, so practically no cars in front. Had there any vehicles behind us, it would for sure rear ended us.

Random phantom breaking when using cruise control at high speeds. Goes from 70-40 mph and always worried someone is going to rear end me when my car automatically rapidly slows down for no reason. Huge hazard and risk!.

We have experienced several episodes of the car suddenly breaking for no reason when using cruise control. The speed is very quickly reduced a good 15 mph without warning. This is not only very alarming as drivers/passengers but it is incredibly dangerous. If there was a car following closely behind us, they would have hit us.

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.

Car unexpectedly brakes while using the cruise control. This can occur multiple times on a long drive without warning and for no apparent reason.

When adaptive cruise control is engaged, the vehicle harshly brakes. This occurs very randomly and is abrupt. The operator needs to quickly take control and accelerate as the speed is reduced significantly. One incident, the speed was 80 mph and it reduced to less than 60.

While driving on 15 freeway between riverside CA to las vegas nv, I put the car in cruise control. While near barstow, the car hard brakes dropping speed quickly. Luckily no other car was near. I changed lanes to pull on the side as I wasn’t sure what was happened, as it actually felt like the car had locked up. I did take the car out of cruise control and that seemed to fix the problem. I’ve used cruise control before and the adaptive braking has been manageable, this was extreme. On 4 June 2023.

The contact owns a 2023 Tesla Model 3. The contact stated that while driving at unknown speeds and making a turn, the vehicle suddenly accelerated unintendedly. Then the vehicle resumed driving normally. While her husband was driving at unknown speeds and approaching a stop, he crashed into an unknown Tesla. There were no reported injuries. A police report was not filed. There was no fire or air bag deployment. The vehicle was taken to a collision center. There were no warning lights illuminated. The contact called the local dealer, where an appointment was scheduled. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 3,048.

While in cruise control, the car suddenly reduced its speed; there is no obstacle in the path of the cat that would warrant such an action. This deceleration is sudden and violent and when it happens is dangerous for following drivers.

I was stopped before turning left into a parking space. I was driving slowly. The car stopped but I did not engage the brake as a Tesla will stop once the foot is removed from the accelerator. At that point the car leaped forward at full speed hitting parts of a building and a fence. I did not step on the accelerator. No one was injured. The airbags did not deploy even though there was $17,000 damage to the front of the car. There were no warning signals. The person inside the building was waiting for me and saw the car come to a stop.

This incident is reported by a law office. The car being driven by our client was a Tesla Model 3 which made a sudden unexpected acceleration when our client was slowly looking for a parking space at a parking lot. The Tesla car suddenly accelerated at a high rate of speed without client pressing on the accelerator. On the contrary, our client was stepping on the brakes in an attempt to stop it but the Tesla did not stop but still continued to accelerate. This accident caused property damages and injuries to our client, his passenger, and others.

When driving and using “autopilot” or just cruise control, the vehicle will randomly brake. Sometimes it brakes lightly, but sometimes it will violently slow the vehicle down, without warning. There is no obstacle in front of the vehicle. If another vehicle is behind the car when the car randomly brakes, this can potentially cause a rear-end event or potentially cause the car that is behind to swerve to avoid an accident. I submitted a service request to Tesla, but Tesla responded by stating that there was no malfunctions that needed to be addressed. They described various scenarios in which the computer would determine a need to brake.

While crossing the rump and side walk to garage the car, as usual slowly proceed to enter the garage but immediately the car went into extremely fast speed by itself and hit the side of the garage, damaged the garage wall, the garage opener, the cabinet, then hit the water softener and our other car in the front. It also smashed the bike against the wall , damaged the side wall cause a bulge to outside of the structure. The garage frame and right side of the garage door fell on top of the car almost killed our daughter who was at the front passenger seat. The car brake did not stop the car, the alarm did not go off, the air bags did no inflate.

At random times the vehicle will slam on the brakes although there is nothing in front of it. It has happened with vehicles behind me and I have averted multiple crashes by luck I suppose.

While exiting a hospital parking deck, after driving for approximately 15 to 20 seconds, the car began to accelerate to an uncontrollable rate of speed on its own. The Tesla crashed into a parked car which was then pushed into two other parked cars. The Tesla and at least the first car hit are totaled. There was no sign of the emergency braking system engaging. Injuries from the airbag deploying were sustained. The driver has a fear to drive again as the car seemed to have a mind of it's own. The Tesla is being held at the insurance company's tow yard. There has been no feedback from the dealer. No inspections have been conducted on the car. There were no indications there was a problem with the vehicle previous to the crash. It is unknown if any warning alert systems activated during the incident.

Driving west on 1-10 west of tlh vehicle suddenly decelerate if if there was slowed or stopped traffic ahead. I was alone on road.

Back in February my Tesla Model 3 started acting up emergency brake was disabled, automatic vehicle hold was disabled, and traction control was disabled all issues I reported to the company app with photo. This problem stated when a software update happened after the Tesla app requested it.

Picked up car from the dealership same day and had only 40 miles total on odometer. The car was running smooth. I was driving with my daughter in the passenger seat (12 yrs old) and got 2 error codes and my car went limp in the carpool lane. Basically went into neutral. Deceleration from 75mph . I had to avoid cars next to me to get to the shoulder and was driving at most 30-40 mph hoping a car would not slam into my rear. By the grace of god I made it to the shoulder safely. “acceleration and top speed reduced” and “automatic emergency braking is disabled” were the two errors. I’d never been so stressed. That was highly dangerous and I’ve been reading online of several other Tesla owners suffering the same fate. Please don’t wait until someone gets injured or killed before making Tesla recall their cars. I’ve been hearing its the rear drive inverter (motor) that is faulty according to others online. The service center has not diagnosed the problem with my car yet but I think that is the same issue. I feel that Tesla is negligent and should be penalized for allowing these cars to be driven off the lot by unsuspecting customers.

While traveling on the interstate at 75+ mph, which the cruise control engaged, the vehicle emergency braked 2 times during on one trip. The first felt like a fluke, speed was reduced by 10ish miles per hour. The second time was terrifying. I was traveling approximately 77 mph on the interstate and out of no where my vehicle slowed down significantly. I was too scared of getting hit from behind to look at the speedometer to know how much it actually breaked but it felt like it dropped down to 30 mph out of nowhere. Luckily I was not on a busy stretch of interstate, the car behind me had enough time to slow down and there was no one else around. My husband and I were scared out of our minds, wondering why and how this happened. He immediately google and that is when we learned of 'phantom breaking" I have owned this car for less than a week and now I am scared to use cruise control. I don't even have the self driving or advanced auto pilot. Thank god no one was hurt. This is more than a safety issue, this could be life and death. I read that this particular issue has been reported more often lately. I reported the problem to Tesla but urge you to conduct an investigation that gets this matter resolved, not just for Tesla drivers but for the safety of everyone on the road.
