I was traveling on the 8 freeway in Az going around 80 passing a tractor trailer. I had the cruise control on. Then the car breaks for no reason dropping me to 50 mph. It happened maybe 3 other times on that trip. Maybe 10 times since I purchased the car 5 months ago

The contact stated that the vehicle failed to stop. The contact stated that his wife used the parking brake to stop the vehicle. The contact was concerned that the failure could cause injury or an accident. The contact stated that the tire pressure warning light was illuminated. The vehicle was taken to the dealer where the cause of the failure was not yet determined. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 3,800.
The contact owns a 2023 Tesla Model Y. The contact stated that while driving approximately 15–20 MPH, the vehicle experienced unintended acceleration. The contact then depressed the brake pedal, and the vehicle stopped immediately. No warning light was illuminated. The dealer was made aware of the failure but confirmed that no failure was found after reviewing the computer data. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 3,000.
on a recent 800 mile road trip, there were no less than 7 incidents of the vehicle suddenly braking on its own while on cruise control with no vehicles in front of us. one incident occurred with a semi truck behind us that almost caused an accident. the car went from 80 mph to 45 mph before I had time to react and press the gas pedal.
Tesla Model Y purchased on 06/23/2023 from Springfield NJ center. I had 2 accidents on the same day. I having been driving in the US from more than 5 years and never had a scratch on my vehicle nor even a parking ticket. i drove approx 600 miles in 2 weeks. So I was very comfortable in driving the tesla model y. Date of incidents - 07/07/2023. At Tinton Falls NJ. I was trying to take a K turn on a flat road at around 9:30 a.m. I put the car in Reverse. When I pressed the accelerator pedal the car went forward and hit an Electric Pole. I then pressed the brake pedal . Made sure the car is on Reverse Gear . On leaving the break pedal the car was automatically moving forward towards the pole. This should never had happen. I put the car in Park mode and waited for 5-10 mins approx. Then after some time when I put the reverse gear and left the brake pedal the car didnt move and on pressing acceleration it reversed. I parked my car at the site where I had my work. Police were called and they gave me a ticket. I had a sprain in my neck. Later by 2 pm I drove with the same car Home at Edison NJ. (1 hr drive) I called Tesla Customer Service and they advised me to take the car to Springfield NJ dealership as it could be a software glitch. I decided to drive the tesla with my family in other car to the dealership incase they decide to keep the car. I was about to enter into Fadem Rd when lifted my feet off the acceleration pedal to slow down. The car all off sudden accelerated with no steering control. I noticed lots of car on the street and a lady exiting out of near by Staples Drive Way. I grabbed the steering and rotated it all the way to the right to avoid any of them, hit a pole on the passenger side , pressing the brakes really hard and hitting a bush. The car stopped, no air bags deployed , no warning signs nothing. I was in a shock and pain . EMTs took me to ER , I had severe muscle sprain and still recovering.
Sudden unexplained Phantom Braking. Travelling on The Chisholm Trail Parkway tool road and while approaching an underpass the car suddenly applied brakes with no cars near me in front or to my sides. Fortunately there were no vehicles behind me. This similar situation also happened to me in my 2022 Model 3, so it is apparent that Tesla has not been able to resolve this long standing potentially serious traffic safety hazard.
While traveling on I70 from Columbia, Missouri to Grand Junction, Colorado and back, we experienced at least 30 incidents of sudden braking while in adaptive cruise control. Some of the incidents were rapid, causing the car to lose 20 to 30 mph within a second. For the most part these occurrences of sudden braking happened on open highway with no other vehicle within 1/2 mile in front of us. We discussed this issue extensively with Telsa and no resolution was provided by Tesla. In fact, one service agent stated that we should just be happy that we were driving a Tesla and that eventually Tesla may solve the problem.
I was about to park in car space in a parking lot. Instead of stopping in the car space, it has accelerated suddenly into the lawn in front of the car space. Tried to stop and it accelerated again and then hit the tree. The left front part of the model Y is damaged and is still in the body shop even after more than a month. I thought the only explanation is I have pressed accelerator instead of break. But as I think about it, I don't think I pressed the accelerator. It did sudden intended acceleration twice during that incidence.
The adaptive cruise control malfunctioned while engaged on the highway/interstate. On a recent trip of approx. 1,000 miles, the vehicle experienced "phantom braking" (aggressive emergency braking for no reason) on three occasions while the adaptive cruise control was engaged on the highway/interstate at approx. 65-75 mph, with no obstruction/vehicle in front and the weather was clear sunny skies. No warnings or messages were prompt by the vehicle. This abrupt phantom breaking could have caused serious injury from a rear-end collision or cause vehicles behind to take unnecessary unsafe emergency maneuvers/braking.
Hard braking on its own while using cruise control. Nearly rear-ended multiple times.
Drove thru multiple states in spring and Tesla autopilot would come to abrupt sudden slow down without warning. Bad enough that I would disable the system and drive manually. This problem occurs regardless of one lane or two lane roads. With or without cars in front or behind me. Sunny or cloudy skies. Hot or cold. Straight or windy roads. With autopilot or even adaptive cruise control. I have no faith in the system. At one point it even changed lanes without warning almost hitting another car.
While driving in cruise control, the car suddenly decelerates periodically from 75 mph to 50 mph. No immediate safety issue but if a car had been following, we may have had a collision. We logged this with Tesla using “bug report”. No warnings. No inspections yet.
Phantom braking issue- Brakes were automatically applied while driving on open highway with no other vehicles around. Autopilot was in use, speed set to limit of 75 mph.
Tesla's Autopilot feature regularly experiences "phantom braking". A typical scenario is while traveling on an interstate highway in Idaho, Oregon or Washington state at the speed limit (70 to 80 MPH), the car will suddenly and violently decelerate. The severity can vary between annoying to so extreme that the passenger is thrown forward hard enough to engage the retention mechanism in the seat belt. This happens under seemingly perfect conditions-- mid-day, clear skies, clear lane markings, smooth pavement in good condition, straight section of road. The deceleration can be overridden by pressing the accelerator or disengaging autopilot but by that time the risk of being rear-ended by anyone traveling close behind is very high. For this reason I've been using the feature less and less which leaves me without any form of basic cruise control. In two different trips of around 500 miles, phantom braking has occurred between 10 and 20 times each. In two different service requests, Tesla has confirmed that my car, including the vision system, is operating within normal specifications. Beyond that they're unwilling to engage in any form of diagnosis or investigation. There are two fundamental problems here: 1) Tesla's Autopilot feature in unreliable and dangerous 2) The car I purchased was advertised to have Cruise Control, implemented by Tesla with their Autopilot feature. Because of 1), it effectively has no Cruise Control.
While driving highway speeds in autopilot (cruise control) I experience sudden heavy breading for no reason. No cars around on a flat road. Once while in front of another car which scared me enough not to use it anymore.
During our road trip today on the HWY cruise control was engaged. without warning several times the car decelerated from 75 (speed of traffic) to 50 which could have caused an accident had other cars been following closer. We can no longer trust the cruise control mode as this is a serious safety concern.
While driving at highway speeds with the cruise control engaged we have experienced several ghost braking events. Fortunately no other cars have been behind us.
Intermittent braking while in cruise control for no reason. Nothing in the way, no cars around. Reduces speeds from 10 t0 50 miles per hour. At time it reduces speeds almost to a dead stop. If another car was behind us, could cause a serious crash. Happens at random times.
The contact owns a 2023 Tesla Model Y. The contact stated while driving at an undisclosed speed and attempting to accelerate, the accelerator pedal vibrated briefly before returning to normal functionality. The contact stated that the failure was intermittent. There were no warning lights illuminated. The vehicle was taken to the dealer; however, the mechanic was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 5,000.
Multiple moments of phantom braking 15+ times TODAY driving from North Platte, NE to Havelock, IA on cruise or auto pilot. Extremely dangerous, could've caused pile ups/rear end collisions. Screen would 50% of the time show a semi or vehicle in front of me when nothing was there. I tried cleaning the windshield, thought it helped for a bit then it happened again. This happened on both interstate driving and highway driving into the sun and not into the sun. Could be very hazardous - very abrupt emergency braking at interstate speed limits. at the Shelby, IA super charger, another Tesla owner expressed he had also just reported multiple phantom braking incidents today as well and reported it to Tesla.
Just returned from round trip from Kansas City Mo. to Denver Colorado. Used the cruise control quite a bit on the trip. On 10-15 occasions the regenerative braking automatically came on for no reason.In one instance I was driving the 75 mph speed limit and a car was following too close when the regenerative braking activated and almost caused a crash.It seemed a lot of the times it happened on a bridge but not all of the time.Nothing was in front of me that should have caused this to happen.
I am finishing a drive across the country and every time I put my Tesla into cruise control or adaptive cruise control, it will eventually abruptly break for no reason, in traffic with cars. It can only be restarted by stopping the cruise control feature and turning it back on, after which it inevitably happens without any warning
My Tesla Model Y is experiencing phantom braking, due presumably to a faulty collission avoidance safety system. With cruise control enabled (not autopilot with lane keeping, only cruise control by depressing the stalk once vs. twice for lane keep) the car will phantom brake, where it slams on the brakes thinking their is a vehicle in its path when there is no vehicle in the front lane. This has happened to us on a clear toll road in Southern California on Hwy 73, both on June 7th, 2023 and in April/May 2023, where the Tesla slams on its brakes, decelerating us from 65mph to 38mph and below (at which point I slammed the accelerator pedal to avoid a rear end collission), with vehicles directly behind us, almost causing a dangerous accident. This happened with my three children in the back seat. We have experiencing this phantom braking twice in the last 2 months. In all cases the vehicle was well centered in the lane and there was no vehicle in the lane ahead of us, nor did we recently change lanes. I created a service ticket with Tesla, including bringing it into the service center at Lake Forest, CA, as scheduled, and they explained in person that there is nothing they can do, that they are unable to retrieve any video footage from the vehicle, and sent us away without even looking at the vehicle, replacing any hardware, hardware testing, or test driving it for themselves. We are at a complete loss of what to do with this vehicle that is only 6 months old. The vehicle has no warning lights or error messages prior to any of these failures. I feel that this vehicle is unsafe for my family to drive and Tesla is not putting forth reasonable effort to fix the vehicle.
Car under adaptive cruise control braked hard after changing lanes from behind another vehicle to an open lane with no traffic. Went quickly from 65 to 20 mph until driver started accelerating manually
The Adaptive Speed Control will randomly, abruptly decelerate the vehicle for absolutely NO reason. This certainly is safety item if a car were following me. With the Tesla set in the "Hold" setting for regenerative battery charging purposes, this is the same as slamming on the brakes. Also, this vehicle now only utilizes cameras for sensing everything and it falls short in this area. Other times this happens includes: Orange cones in construction areas, a vehicle crowding the center line in multi-lane highways and also, vehicles traveling the same direction ahead of you in a curve. In these instances, cameras and or computers processing the camera information is getting it wrong...
Phantom braking at highway speed. Maybe a shadow or line on the road confuses the system and slams on brakes. Is more common if the cruise is engaged. Happens every day. My commute is about 30 miles happens once or twice every drive. Increases risk of being rear ended. The car is not FSD enabled.
I experience multiple and frequent phantom braking events when using the Active Cruise Control. This continues to occur every time I use cruise control, and occurs even on straight empty roads on bright sunny or overcast days, and creates a serious safety issue for any vehicles that are following. The deceleration is rapid because of the regenerative braking capabilities of the vehicle. There are no warnings lamps or indications associated with these random braking events. The vehicle has not been inspected by the manufacturer, but my research shows this is a common defect reported by many Tesla owners. Tesla should, at a minimum, provide a software option to deactivate Active Cruise Control and make it a non-traffic aware system until such time as a bug proof system can be produced.
We upgraded our auto pilot to the advanced auto pilot system and when driving from Denver to Santa Fe the Tesla would brake abruptly without notice or reason. The braking reduced speed by at least 30-40 mph in a matter of a second or two. This occurred 6 times during this drive. The concern is if this happens when other cars are driving behind our car, it will cause a collision.
This has been a consistent on-going issue with my brand new 2023 Tesla Model Y. While using Autopilots Traffic-Aware Cruise Control and the Autosteer feature the car will without warning begin braking. Each time is different in regards to severity of the breaking but it is typically like letting off the accelerator pedal which in a Tesla is comparable to significant breaking. Have taken two highway road trips and on both trips, the phantom breaking has occurred multiple times. Some of the incidents the car would go from 75MPH to 45MPH in a matter of seconds. From research done, this "Phantom Breaking" is a serious issue that Tesla says is due to software issues and not hardware issues. Our safety was put at risk because the person behind us might not be paying attention when cruising on open road, during daylight, etc and could rear-end our car. There have been no predictors or weather conditions that cause the braking. Usually, for us, has happened on sunny days on multi-lane highways with not a lot of traffic. Have taken car to dealer and they state it is a software issue. No warning signs that the breaking would happen and no objects or cars show up on the screen when it happens.
2023 TESLA Y -Consumer is writing about concerns with the speed assistance, auto-pilot (quick stopping action). Consumer was unaware of the dangers and that there was no cruise or lane control. Consumer submitted service request. Consumer has listed summary of observations & incidents. Consumer listed several questions: Are all Tesla Y prone to phantom breaking? Did we get a lemon? Can we get it fixed? Can Tesla replace the computer? Can we get a replacement car? Can we make the sales go back and instead buy a safe car? Do you have to be in an accident, having someone injured or having someone killed for Tesla to provide a warning to customers of Tesla Y? As a new Tesla owner what I the next step? Can we trust our Tesla Y not to cause an accident? Should we garage the car until Tesla has made its needed software updates? Can we return the car to Tesla? Get it replaced?
