2021 TESLA MODEL 3 Complaints

“Phantom emergency braking” problem while cruise control engaged. Occurrences are unpredictable as to causation. Examples of emergency braking include: - no apparent reason: no vehicles nearby, no obstacles in road - cresting a hill - bridge overpass - highway overhead signage - vehicles on side of road - vehicles crossing highway but at a distance that is not dangerous - passing large vehicles on highway This problem causes anxiety driver. could likely create a very dangerous scenario for vehicles following behind should emergency braking engage

Phantom braking. The Tesla brakes without warning or provocation when on cruise control. On two lane roads brakes deploy forcefully every time a semi truck is traveling in the on coming lane. It does not have to be on a curve. It is every time a large truck is in the opposing lane. On 4 lane divided highways, it will forcefully brake (from 75 mph down to 40 mph in seconds) climbing small hills, patches of tar on the roads, shadows, off ramps, side roads and for no apparent reason. I have almost been rear ended when a car is following closely and it happens. I have recorded these incidents , reported to Tesla, taken the vehicle for diagnostics and they have no answer and imply that occasionally it may happen however, it should not be an issue. IT IS A DANGEROUS PROBLEM and an accident waiting to cause serious injury. I drive daily with my job and it happens every day.

The automatic braking system performs pretty well on interstate highways. However, on two lane highways and secondary roads, heavy braking occurs for no apparent reason and with no warning resulting in several near misses for rear end collisions. I can solve the problem by not using cruise control; but, cruise control prevents me from unintentionally speeding. Either this unintentional heavy braking needs to be technologically resolved and/or I need to be provided with the option to switch to conventional cruise control in which I set the speed and determine when the cruise control is deactivated. THIS ISSUE HAS OCURRED DOZENS OF TIMES DURING MY 5 MONTHS AND ~10,000 MILE OWNERSHIP.

I received delivery of a Tesla Model 3 Long Range vehicle on Oct 25, 2021. On nearly every occasion that I use the “autopilot” cruise control feature, one or more phantom braking events occur. When this happens, my vehicle decelerates rapidly and without warning with enough force to thrust my head and upper torso forward. In all cases, there is nothing in the road and no perceivable road condition to warrant this behavior. Fortunately, no one has been close behind me yet when this has occurred since it would surely result in a rear end collision. There appears to be no consistent pattern: it happens on sunny and cloudy days; day and night; highway and surface streets. I have gotten into the habit of leaving my foot resting gently on the accelerator when in autopilot mode in order to react quickly to these events and hopefully avoid a collision. On Dec 17, 2021 I mentioned this issue during a service appointment at my local Tesla dealership. The response was that this was a common and known problem with Model 3’s and would be hopefully worked out in future software updates as the system “learns”. Four software updates later, the problem has not been resolved and in fact seems to be occurring more frequently. I believe this phantom braking problem is a serious safety issue that Tesla should immediately address.

I was driving down the freeway at highway speeds. A motorcycle passed me in the left lane. My car sudden slammed on the brakes at freeway speeds and if a car was following me closely I would have been hit. The motorcycle did not cross my path and I was in no danger of hitting it. I was using cruise control at the time. This has happened more than once. Usually it is when a motorcycle is around. I have stopped using cruise control if I see a motorcycle on the road.

Forward Collision Warning and Automatic Emergency Braking system failed/malfunctioned. The car is in a Tesla authorized body shop for inspection. The airbag deployed and prevented any injury but the accident did put my life and others at risk. The car was inspected by Tesla's authorized body shop. There was no warning lamps, messages, or other symptoms of the problem prior to the failure. The car was brand new, and I believe a possible explanation is Tesla taking out the radar and replacing it with Tesla vision. I tried to contact Tesla for an investigation but no response. I received a 30k bill to fix the car, and Tesla did not take any responsibility. Here is the footage: https://www.dropbox.com/s/sat1w5i0gl6bwsr/2021-12-20_10-56-45-front.mp4?dl=0

While on autopilot I experience regular abrupt phantom breaking around semi trucks. This has nearly caused several accidents. I will be going from 60 mph to nearly full stop. This is incredibly unsafe and I no longer feel comfortable using this feature around semi trucks.

Cruise control will slow abruptly without notification or apparent reason. Driving in the middle of the desert on an interstate with cruise control activated and the vehicle will suddenly apply emergency braking for no apparent reason. No other vehicles in close proximity. No crossroads, overpasses or entry/exit ramps in close proximity. Braking event occurs every time cruise control is initiated and occurs several times in one session. This is a critical safety hazard and needs to be addressed immediately. If a large truck was following close behind, they would not be able to slow in time which could have deadly consequences. Tesla shows no concern to fix this critical flaw in an expeditious manner. This needs to be investigated and corrected immediately before someone has to pay the ultimate price.

Tesla is phantom breaking for no reason. It could cause me to be rear ended by another car. This is happening more and more to me. Tesla purchased in Oct.

When pressing the horn in the center of my steering wheel, it only activates when certain regions are pressed. When pressing certain regions of the wheel, such as the bottom half of the wheel, a switch is heard clicking, but the horn does not activate. This issue has been reported elsewhere on forums with videos e.g. in one case where the left portion of the wheel's center area did not activate the car's horn. I have discussed this issue with my local Tesla service center on four occasions and demonstrated it to the technician. But the issue is never addressed and I have now been told that bringing up the defect will incur fees from the service center. https://teslamotorsclub.com/tmc/threads/model-3-horn-issue-check-the-left-side.137767/ ^Here, there are at least 47 reports of the issue occuring, based on the thread's poll. I wouldn't mind this issue terribly much, except there has now been 3-4 separate incidents where I have had to use the horn in an emergency situation (e.g., when another car is changing lanes without noticing my car next to it). During these incidents, I was either unable to activate the horn, or only able to activate the horn in a delayed manner as I worked to activate the horn by pressing it in a specific manner to enable it.
