Traffic aware cruise control is dangerous to use. Automatically slams on brakes on 2 lane roads with large vehicles in oncoming lane. Brakes at the top of any sort of hill, brakes for shadows of overpasses on the highway. System is dangerous and has caused several situations where I would have been rear ended on 2 lane roads and larger highways. Recent road trip had almost a dozen phantom braking events on a one hour drive on a straight 2 lane road during the day.
2022 Tesla Model 3 acceleration complaints
Page 7 of 7: complaints 161 to 171 of 171, newest first, as owners wrote them.
When using cruise control (TACC) with or without using lane centering (Autosteer), my vehicle will often brake suddenly (and harshly) for no reason at all. It's worse on undivided highways (with no median). I've noticed the phantom braking occurs most often when an oncoming tall vehicle (18-wheeler, RV/motor home) approaches, or I approach an underpass, or I approach a large shadow on the road (from a building or large tree). During a 90-mile trip last weekend, my car phantom braked almost a dozen times, sometimes severely. Fortunately, no one was following close to me. I feel this is a safety hazard and should be fixed.
Vehicle frequently brakes hard to prevent a collision with an object that does not exist. Also known as phantom breaking that is a commonly known issues with Teslas autopilot.
The vehicle is having a very serious problem with phantom braking whenever the cruise control is engaged. The problem occurs randomly regardless of road conditions or traffic conditions. While driving at any speed with cruise control engaged the car with randomly brake hard and sound an alert. The road has always been clear of obstructions and debris. It will also engage braking abruptly when a large truck or bus is coming towards me in the opposite lane on a two lane road. At first I thought it was an anomaly. But now after 3400 miles of ownership I fear for my safety while driving because of the conduction. To the point that I have stopped using the cruise control and auto pilot because of the issue. Considering that autopilot was one of the main reasons for me to purchase the vehicle, it seems like I have been missled and sold a vehicle that is unsafe for public roads.
The autopilot feature which keeps the car in it's lane and speeds up or brakes the vehicle based on its surroundings is not functioning properly. It slams on the brakes whenever a semi-truck or large vehicle is driving in the opposite lane on a two-lane road. Especially if there is a bend in the road. It thinks that a forward collision is going to take place.
When driving with cruise control on the car will suddenly apply brakes if it detects a car coming at me from the opposite lane. This is a safety hazard as the cars behind me would have no idea I would be stopping and poses a serious rear end threat.
Phantom braking in city and highway with no obstacle in vehicle path. Sudden and strong emergency braking enough to cause a rear end collision if being followed. Very scarry in one 700 mile road trip we had 11 such occurrences . Thank you for your help. Mike
As widely reported by Tesla owners, I have also experienced issues with the TACC - traffic aware cruise control - feature of this vehicle. I have owned it for almost 2 weeks and in that time on both highways and city streets the 'cruise control' feature has initiated braking for no reason. The system is supposed to be 'traffic' aware however in these instances there was no vehicle in front of me in any position to cause a braking event. This type of erratic behavior could easily cause an accident (being rear ended). This is happening when the 'autopilot' feature is not engaged, but rather just using the only available cruise control feature the vehicle provides: TACC. It seems as though the software is interpreting shadows, changes in painted line/lane markings, or other environmental stimuli as 'traffic' and reacting, but that's just a guess. All I know is that it is very annoying at a minimum and potentially quite dangerous!
VERY AGGRESSIVE phantom braking on two lane highways and at night with oncoming headlights. Car will reduce speed by 30mph or more in seconds. This is a new car, a month old. Tesla says cruise is part of autopilot, but we turn autopilot off and just use cruise and it still does it very often. It is extremely unsafe. The internet is full of similar complaints. We need NHSTB to pressure Tesla to fix this. It is a major safety hazard.
Three incidents within 5 minutes of what Tesla owners call "phantom braking" whenever the car has cruise control on. For no predictable reason and no warning the car brakes suddenly and forcefully - could be shadows, reflected lights, oncoming traffic, who knows. It is a scary phenomenon and caused me to get in very dangerous situations - almost got rear ended at 60 mph. This is after owning the car for only 10 days. Called Tesla and they had no answer except to say that the car "will learn."
**Im well aware that Tesla's AutoPilot system is not autonomous** There is no 'dumb' cruise control option on Tesla Vehicles, only Traffic-aware-cruise-control (TACC). TACC is unusable, and quite frankly dangerous, on any single-lane divided road. Anytime a large vehicle, such as a semi or box truck, passes by in the opposite lane, my car abruptly and aggressively brakes while TACC is engaged. This poses a danger to myself and others behind me. Im filing this complaint in hopes that it will coerce Tesla to address this issue faster.
