2021 TESLA MODEL 3 Vehicle Speed Control Problems

My Tesla Model 3 is brand new and delivered in 2021, the vehicle has had no recalls or issues report by the manufacture and is running the latest software updates provided by Tesla, which as of this date is: 2021.36.8 I have driven the car since delivery a total of 5,596 miles, which includes a cross country road trip from CA to FL. During this trip I used "Autopilot" a feature which is touted as safe, however after my experience and reading and hearing other users reports I believe this is not the case. I had numerous cases of "phantom braking" which is where the vehicle believes there is an object that it will collide with and it slams the brakes on, usually dropping around ~20 MPH extremely rapidly. Many of these events occurred in lower light scenarios (night time) and almost all of them occurred when I had no...

Driving normally, with cruise control (not auto steering) engaged vehicle will spontaneously and dangerously apply emergency breaking. This happens regularly to the point I won’t use it. It’s going to cause accidents, especially when slippery conditions exist.

My new Tesla 3 deployed automatic emergency braking seven (7) times in a 5 hour period. The Tesla Autopilot was turned off due to reports of phantom braking like this from many other drivers in a Tesla online forum. Regardless, the car slammed on the brakes when there were no obstructions or cars in front of me. I almost suffered a rear end collision during one of these phantom emergency braking events, where the car suddenly braked from 70MPH to less than 40MPH. The malfunctioning component is likely the Tesla software that works with the forward-facing cameras which are installed as part of the Full Self Driving feature. While I did not pay the $10,000 for FSD, this system still operates for automated braking and lane departure. I have requested Tesla inspect the car, which has 482 miles on it, but am filing with you anyway due to the similarity...

On a recent trip, we started experiencing extreme issues with our car's cruise control and autopilot features. Specifically, when in cruise control or auto pilot, the car would randomly disengage the cruise control or auto pilot and start braking. Taking the car out of cruise control or auto pilot, restarting the car, etc did not fix the problem. We noticed the problem was much worse at night and when we were traveling on a two lane highway. We would be in cruise control/auto pilot and often when another vehicle would approach us from the opposite direction the vehicle would suddenly brake. While this happened more often at night, it continued to happen at any point during the day and when we were on many different roads/interstates. This seems extremely unsafe to have our vehicle hard braking randomly when we are traveling at high speeds (60mph+). We scheduled a service appointment...

Whenever TACC (cruise control) is engaged and the car is on a two lane highway with no divider, it will aggressively brake and trigger the collision warning system when a semi-truck passes going the opposite direction.

"Traffic Aware Cruise Control" (aka Autopilot) applied full braking and sounded collision warning when no collision was imminent. Had traffic been following closely, a rear-end collision could have occurred. Several other similar "ghost braking" incidents have occurred but this was the worst and most dangerous. Vehicle has not yet been taken to a repair facility. Vehicle has not needed inspection by law enforcement nor insurance company.

Starting in June 2021, Tesla removed the radar sensing on their vehicles and switched to a vision-only (camera) system for adaptive cruise control and "auto pilot" operation. On my 2021 Model 3 Performance, I can not use either system without constant "phantom braking" events. Sometimes it will only gently pulse the brake pedal, but often it is very hard braking along with a beep and message on-screen saying I need to take immediate control of the car. This happens daily and is not hard to reproduce. If there is a car behind you, it can be quite dangerous. Even if they don't rear end you, often it will cause them to think you're doing a "brake check" and can lead to road rage incidents. My previous car (a 2018 Model 3 RWD) had a radar sensor and experienced mild (not hard) phantom braking roughly 2~3 times over an 18 month...

Autopilot constantly brakes due to automatic emergency braking on two-way highways at night. Every time a car passes in the other direction, the car starts braking, often as soon as the headlights are visible. This is a significant safety issue and resulted in me disabling AEB, which re-enables automatically every time I drive. I needed to go out of my way and ensure no one was tailing me because the car would brake check them. This wasn't an isolated incident. Every time I've been on a two way highway and sometimes even on multi-lane unlit highways, I have these braking issues constantly. I was driving under the speed limit.

Vehicle slams brakes on with on coming traffic when cruise control activated. Have attempted to contacted Tesla several times. Tesla actually canceled a mobile service stating they did an update to fix the issue. It did not. In fact it made the problem worse. The are not answering my emails or texts, calling the service line does no good the say they can’t see the issue in their data

I noticed you have a recall for SOME Teslas about a glitch with the auto braking after latest Beta FSD rollout. My Tesla has had this since day one, and I don't have or use FSD. I do use the adaptive cruise control, and that is when I have problems with my car slamming on the brakes for no reason. I have been lucky, 3 times I have ALMOST, been rear-ended. I have had it in the shop a couple times for the issue, and they tell me to read the manual and the car is fine. I have talked with 5 other Tesla owners, and they have all had the problem of their car slamming on the brakes for no REAL reason. I think the GLITCH is a bigger problem than Tesla is willing to admit, and applies to most Tesla cars. there are even website forums about, "Phantom...

On September 1st, I was perpendicular back parking on the street in front of my home. Spaces are fairly tight and the street fairly narrow, so it is not uncommon to shift between reverse and drive a couple times to adjust one's fit before parking. That said, a quarter of the way into my parking spot, I shifted from drive to reverse after finishing adjusting. After doing so, I pushed on the accelerator and was sent forward as if I were in drive. I toggled between drive and reverse multiple times over the course of 15 seconds. Pushing on the accelerator continued to send me in the opposite direction, causing me to hit the sidewalk curb in front of me multiple times. The situation resolved itself after 20 or so seconds. Then, the same exact situation occurred on Sept 7 and again on Sept 13, and those times, I nearly...

I was pulling up next to a curb inside a neighborhood to park my car. I released my foot on the accelerator pedal to slow and stop my car. I slowly stepped on the brake pedal to switch the gear into reverse and my vehicle sped up very fast and hit the parked car in front of me and ran over the curb, my steering wheel also shifted to the right as if it was trying to dodge an obstacle on the road. It happpend so fast that I could not avoid the impact. I could have ran into a pedestrian and put their life at risk, or injured the person in the car that was parked, and even hurt myself badly. I've been getting neck pain and headaches. This incident was very terrifying and traumatizing. I tried to reach out to Tesla Service Center, but my tesla app was...

When driving with the adaptive cruise control on, the car will for no reason, briefly slam on the brakes for no reason. I have almost been rear ended twice because of this. check mark box above in this web page would not allow me to check the adaptive Cruise Control item.

After parking and leaving the car, I realize later the dashboard did not shut down. The dashboard was still illuminated, and I was also able to hear the sound from a tuned FM radio. I re-open and closed both the driver and the passenger doors in an attempt to shutoff the dashboard. Since I did not get the expected result, I decided to get back into the car. I sat down in the driver chair to investigate the problem when the car was instantly activated and switched to a sudden and uncontrolled acceleration. It crashed into a facing wall after a run of about 30 feet.

I previously reported unexpected acceleration on two occasions with this car. This follow up not is to inform NHTSA that Tesla has not been willing to provide any information or investigation results more than 8 weeks after my report to them. They told me they couldn’t discuss it and I would be contacted within 5 weeks. When I inquire now they just say it’s still under investigation.

On two separate occasions our Model 3 experienced uninitiated acceleration. Both times we were able engage the breaks and prevent any issue, but it’s disconcerting. We reported to Tesla on April 22nd and they said they would get back to us.

ON FEBRUARY 28, 2021 AT 4:08 PM.. THE APPROXIMATE TIME OF MY ARRIVAL AT WORKPLACE WHICH IS ALSO DISPLAYED IN MY NAVIGATION. AS SOON AS I'M DOING A REVERSE TO PARK MY TESLA FOR SOME REASON AND IT DID HAPPEN SO QUICKLY ACCIDENTALLY PRESS THE ACCELERATOR HARDER AND AS A RESULT I CAUSE AN ACCIDENT THAT MY REAR BUMPER HIT THE CAR BEHIND ME THAT WAS PARKED. THE DAMAGED WAS HUGE THAT IT KNOCK OFF THE PARKED CAR FRONT BUMPER, IT BROKE THE RIGHT HEADLIGHT AND BUCKLED THE ENGINE HOOD. IT REALLY BOGGLES ME AS TO HOW IT HAPPENED, I RE-CREATE THE SCENARIO AT HOME IT TURNS OUT AND I TRULY BELIEVED THAT I GOT CONFUSED WITH THE CURRENT DRIVING MODE AS I SWITCH THE CAR TO REVERSE WHILE I STOP TO CHECK MY PROXIMITY, BUT THE DISPLAY CHANGES TO 'HOLD BRAKE' FONT. NOT KNOWING THAT IT STILL IN REVERSE...

WHEN I TEST DROVE THE TESLA MODEL 3, THERE WAS AN OPTION TO TURN REGENERATIVE BRAKING TO LOW. THIS ALLOWED THE CAR TO HAVE MORE OF A COASTING EFFECT WHEN ONE LIFTS THE FOOT OFF OF THE ACCELERATOR. WHEN I RECEIVED DELIVERY OF THE CAR, THE ABILITY TO REDUCE THE REGENERATIVE BRAKING EFFECT WAS NOT AVAILABLE. THE REMOVAL OF THIS FEATURE IS BEING DISCUSSED AT LENGTH IN ONLINE FORUMS. THE LATEST VERSION OF THE OWNERS' MANUAL STATES THAT REGENERATIVE BRAKING IN THE STANDARD SETTING COULD CAUSE THE CARE TO LOSE TRACTION IN WINTER CONDITIONS AND THAT DRIVERS SHOULD SELECT THE LOW SETTING. BY REMOVING THIS ABILITY, TESLA, BY ITS OWN ADMISSION, HAS DECREASED THE CAR'S SAFETY IN WINTER CONDITIONS. A RAPID DECELERATION OF A CAR ON SLIPPERY ROADS IS ALMOST GUARANTEED TO INDUCE A SKID AND MAKE THE CAR DIFFICULT OR IMPOSSIBLE TO CONTROL. I FIND THIS EXTREMELY CONCERNING. TESLA...
