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.
2018 Tesla Model S brakes complaints
Page 2 of 2: complaints 11 to 25 of 25, newest first, as owners wrote them.
I experienced multiple incidences with phantom breaking today. Multiple times per hour of driving (average of 5 times per hour on a ling 10 hour drive) Events occurred on open highways/freeways with no other vehicles or objects around. Thankfully. But these incidences could have lead to a crash if other vehicles were following closely.
The car brakes when it is on Adaptive Cruise Control mode. The braking happens for no reason. It happens when the car is approaching an overpass. I have to take control of the car immediately.
I purchased the Tesla Mold S with Autopilot feature in August 2018, then upgraded it to Full Self Driving for $5,000 and got it through a software update at the end of 2021. But this FSD feature has many defects such as hesitating before turning or stopping at a sign, which makes the car swing around like a drunk; Sometimes it doesn't turn the turn signal on when changing the line, and even enters into the reverse lane. If the above problems can be taken over by switching human drive to avoid accidents, phantom braking is a terrible safety problem that can not avoid accidents. There have been many times in which the vehicle suddenly decelerated and braked without warning while driving by FSD. Fortunately, the rear vehicle did not follow too close or the rear driver took deceleration measures in time to avoid rear-end collisions. But on January 5 this year, not so lucky, I was just out of the Tesla services center of Berkeley, my vehicle under SFD to the Ninth Street and Gilman Street intersection and is turning left from north to the east after the green light on, but the phantom braking happened when driving road central, the vehicle behind me didn't react and bumped into my car. The rear-end collision not only caused serious damage to the vehicle but also caused very discomfort in the driver's neck from the violent vibration of the collision. Although the accident was dealt with by the insurance companies of both parties and the damaged body was repaired in the Bodyshop designated by the insurance company, I contacted the customer service of Tesla many times and reported the accident to them, hoping that they could arrange a comprehensive inspection to make sure that no other parts were damaged in the accident besides the body. However, Tesla's customer services reacted badly, either prevaricating or ignoring it. The accident has been nearly half a year since the accident happened, but I have not received a positive response or solution from them.
My Model S routinely experiences "phantom braking". I'm driving down the freeway with the Tesla "autopilot" engaged and it momentarily hits the brakes, usually slowing 15-20mph before it either it recovers or I intervene. I've also experienced "phantom braking" with just the traffic aware cruise control engaged and not the "autopilot".
I have experienced many times "phantom braking". When I reported that to a Tesla service center 2 years ago, they did not know of this problem. It is scary and dangerous especially for the cars following me It only happens to me on the freeway when in ADAS mode. There is a exact place on the 5 freeway SB near Disneyland, that each time I drive there, phantom braking happens. Further also random without noticing any reason for it.
Phantom breaking. Car Suddenly breaked on highway going at 70 miles per hour. No crash. This has happened 5-10 times over the last year
I purchase a used 2018 Tesla Model S about two months ago. Braking is very "jerky, causing me and my passenger to "lurch forward" unnecessarily. I run into this "phantom braking" issue numerous times every time I drive. It happens both on Automatic Cruise Control and FSD and under different circumstances" and encompasses: (1) Sudden braking for no apparent reason; (2) Sudden braking that is unnecessary or is too forceful for the circumstances; (23 If the car is on automatic cruise control or FSD, it will slow down and stop too far away from the car in front. So, I push the accelerator to close the gap. When I left my foot off the accelerator, the software apparently thinks it's too close the car in front, and jams on the brakes unnecessarily. Also, when on automatic cruise control, if the car in front of me goes around a curve and then shortly thereafter stops a stop sign/light, my car, sensing that the coast is clear, will accelerate to the speed limit. as it approaches the curve, which it should not do. Then, when the car in front suddenly comes into view, my car will have to "jam on the anchors" in order to stop in time. While I'd rather be "safe" than "sorry," the degree of this phantom braking should be addressed.
This incident happened some time ago but I read recently about complaints related to "phantom braking" which I also experienced. I was driving on the highway at speed with my cruise control activated. There was no traffic close in front of me, but a large semi was in the lane to my right. This vehicle triggered sharp braking of my car. It was very scary, but I immediately overroad the braking to avoid being hit by a vehicle behind me. I have never used my cruise control since that incident.
While driving at approximately 40 MPH the car suddenly braked by itself! A sound alarm and display indicator were also activated. After a couple of seconds the event resolved without any intervention. Their was no warning lamps or messages prior to the event. At the time I was driving on a divided road and there was light traffic at the time. The car was not on cruise control or auto-pilot. My concern was being rear-ended by the vehicle behind me! The car has not been inspected by anyone since the event.
Recently saw an article that the federal safety agency was looking into "Ghost Breaking" with Tesla cars. This is something we have experienced with our Model S on a few occasions in 2018 and 1029. Haven't been driving that car that much now during the pandemic. Problem reported to Tesla: While driving on US 101 in Bay Area (driving from Milpitas to South SanFrancisco), and the car on Adaptive Cruise Control, the car would suddenly break and resume driving again. This not only scares the driver, but could be very problematic in a crowded lane. Telsa has looked into it when we complained and there was not definitive answer or fix. Hope the recent considerations by the federal safety agency will result in a through root cause and corrective action. Thanks!
The contact owns a Tesla Model S. The contact stated while parking into a parking space, the vehicle started shuddering inadvertently. The contact stated the braking panel button was depressed but failed to respond, causing the vehicle to continue to move forward, hit the sidewall, and inadvertently accelerate on its own crashing into a wall. There were no warning lights illuminated. The air bags failed to deploy. The contact did not sustain any injuries. A police report was filed. The vehicle was towed to the dealer. The contact stated the vehicle was diagnosed however, Tesla had not informed her of the diagnosis. The vehicle was repaired. The approximate failure mileage was 20,000.
It was on friday morning on january 11th 2020 at 8.30am. I was slowly pulling into a parking space in front of my medical office where I have practiced for 21 years. I was in an outdoor parking deck. I touched the brakes to stop the car and the car suddenly accelerated forwards and hit a concrete wall in front of it. I know that I did not hit the accelerator. I was slammed into my steering wheel. My airbag did not deploy. I have been driving for 30 years and have driven a tesla for 5 years. I know the difference between the accelerator and the brake. Tesla claims that I put my foot on the accelerator and drove into the concrete wall. That is not what happened. I have serious safety concerns about what happened. The car was out of my control.
I drove to work on may 2, 2019, and was trying to park in my allotted parking stall on the 3rd level of my office parking garage. My parking stall was along the outer edge of the garage and the only barrier to the outside was a set of three (about " diameter) cables strung between outside columns of the garage, besides a thin perforated corrugated metal sheet outside the cables, acting as a rain stop. I was trying to slowly turn right from the parking aisle to park between two pickup trucks on either side of my stall. When I had turned partway into my stall, my tesla suddenly accelerated into my parking stall at high speed, hit the outside cables, rebounded backwards and stopped about 10 feet from the outside cables. The cables saved me from plunging 3 floors down from the garage. There was extensive damage to the hood and front portions of my tesla. There was also some damage to the metal corrugated sheets outside the cables and a slight dent on the corner of the vehicle parked to my right. I have been parking in my office parking stall for about the past six months without any issue like this. I want to know why my car accelerated like that without warning and why the collision warning system was not triggered by the outside corrugated metal sheet. Also, there was an issue with my tesla the previous evening. When I tried to start my tesla after work, I got the 'systems are powering..' message on the screen and my car would not start even after a long wait. Then, I had to google to find a way to reboot the car computer, by pressing two buttons on the steering wheel. On the day of the accident, I used the intermittent rain sensing wipers for the first time, as there was a light rain. My car is still in the body shop waiting for some back ordered parts. I have asked tesla to do a diagnostics to see if there were any software bugs in the system.
Tl* the contact owns a 2018 tesla model s. While approaching a red light, the speed increased and the vehicle failed to respond when the brake pedal was depressed. The vehicle drove through the traffic light and crashed into a vehicle that was making a left turn. The front driver's air bag and knee air bags deployed. The front driver's side curtain air bags had not deployed. The driver sustained shoulder and back injuries that required medical attention. A police report was filed. The insurance company towed the vehicle to a collision repair facility. The dealer (san diego miramar tesla, 9250 trade pl, san diego, ca 92121, (858) 271-5100) was notified of the crash and the contact was waiting for feedback from the insurance company. The dealer and the manufacturer were waiting to retrieve the information from the electronic data recorder to investigate the cause of the failure. The approximate failure mileage was 49. *bf
