2021 TESLA MODEL 3 Complaints

Car suddenly brakes, also known as Phantom Braking, when in Cruise Control. It does it mostly on 2 lane roads, but it has done it driving on wide open freeways too. It's bad. Makes me feel very unsafe.

On several occasions while driving in the highway with AutoPilot engaged for adaptive cruise control, the car has suddenly applied the brakes very hard when there were no hazards in my lane. This has occurred on curves in the road when oncoming traffic was detected in the other lane and also when there has been a vehicle stopped on the shoulder.

The Tesla model 3 has unexpectedly braked very hard with no traffic ahead of my vehicle. So fast and hard that seat belts had to restrain passengers. This has happened several times while the Autopilot is engaged. This usually is on a 2 lane road and there is traffic on the opposite side of the road. I have noticed if a semi-tractor trailer is approaching on the opposite side it happens 100 % of the time. The auto also steers hard to the right. This is very scary and a vehicles behind the Tesla have no warning either. I have almost been hit twice from behind. Makes a lot of angry drivers behind me. I have not used the feature in a month. I called Tesla and they said this was NORMAL. It never happened until a recent software update and then it started doing this all the time. Please help

When car is driving on autopilot on highway, it slams on the brakes on its own. This has happened 2-3 times.

This car has "Phantom braking" issue. As the autopilot was on, on the freeway, the speed was around 70 mph, it brakes without any obstacles or car in the front, just a not very even road. Speed dropped suddenly, felt like an emergency. This scared me to use autopilot. And phantom braking happened several times. When I raised this issue to Tesla dealership for repair, the answer is - "software updates constantly make autopilot better, and it is in beta and driver agree to it every time driver engage autopilot. Tesla will never force you to use autopilot and can drive normal like any other car."

1) When using autosteer and/or adaptive cruise control the vehicle randomly brakes and very rapidly decelerates. This has occurred on at least a dozen drives, beginning on my first long road trip after owning the car for 2 months. 2) If another vehicle is following my car, we could very easily get into a rear-end accident. This happens at high speeds going from 75mph to 55mph in seconds, so the chance of a collision is high. I also become very scared when this happens which temporarily takes my attention away from driving. 3) No the problem has not been reproduced by a dealer. I live 150 miles from the nearest Tesla dealership. 4) No the vehicle has not been inspected. 5) No warning signs which is why this "phantom braking" is SO TERRIFYING.

While driving on autopilot on the highway at about 65MPH the car applied the brakes for no reason. The car descends in speed aggressively and can easily cause a rear end collision. This has happened randomly before as well.

The contact owns a 2021 Tesla Model 3. The contact stated that while driving at an undisclosed speed with the cruise control engaged, the vehicle would independently brake without warning. The contact stated that he saw an article that referred to the failure as “Phantom Braking”. Neither the dealer nor the manufacturer was notified of the failure. The vehicle had yet to be diagnosed or repaired. The failure mileage was approximately 2,000.

Phantom breaking. Severe application of brakes resulting in up to but not limited to 25 mph decrease of speed when semis are oncoming in other lane. Other times without any vehicles around.

I have owned my Tesla Model 3 with FSD for 9 months and have over 10000 miles of driving in the city and highway. Ghost braking has occurred on many occasions and is worse on two lane highways with commercial trucks approaching in the opposite oncoming lane. The vehicle inappropriately and suddenly decelerates from 65 mph to 40 mph. I have had to stop using FSD and adaptive cruise control because of this erratic issue. Recent trip using cruise control (not FSD) on a 4 lane divided highway (I-70 eastbound) there was no surrounding vehicles, no blind hills, obstacles or inclement weather and the vehicle went from 80 mph to 56 mph within a few seconds, requiring me to disengage the cruise control and accelerate to avoid being rear ended. The cruise control and FSD are dangerous and life threatening due to this erratic problem, please start an investigation and recall to remedy these issues before drivers and passengers are injured or killed.
