2022 TESLA MODEL 3 Complaints

While driving on an undivided highway at night using either traffic aware cruise control or autosteer, about every minute the car would aggressively decelerate up to 15mph. Every time a car would pass in the other direction, the deceleration would be abrupt and would slow to ~10mph below the speed limit. This occurred at least 3 times within a ~7 minute window. The road was straight, unlit, with a 50mph speed limit, and was sufficiently wide to safely pass oncoming cars. Random deceleration with no oncoming cars would be less severe but frequent. I contacted Tesla about this and they confirmed these occurrences but stated it was in response to a curve in the road or a vehicle being detected. They claimed the system performed appropriately. Despite being alert, these decelerations are startling in the absence of visible explanation to the driver. If I was being tailgated, a rear end collision would have been highly probable. I owned a 2018 Tesla Model 3 and have driven the same road at night and never experienced this.

My vehicle brakes suddenly when auto pilot is actuated for no reason. Often times, this is a very abrupt brake. This happens many times every time driven

Sunday, January 2nd, on the way back from Vegas back to Sacramento, on the highway with Lane assist driving, the car suddenly braked going from 70+ miles to almost a complete halt. I was able to steer it into the oncoming lane to avoid the pick up truck from hitting us from behind. The braking system again slowed the car down significantly a few more times on this trip and wee have not used this feature since. Car was bought on December 26th and we are fairly new owners of a Tesla.

When i drive on highway, it out blue slam brake several time i am not sure what trigger it. it was out blue from 70 mph to 50-60mph. i don't see anything around car to trigger phantom braking or brake. also on one lane highway, when semi truck or some car/trucks pass by me it slam really hard few time from 60 mph to 30 mph instant, some car almost hit my rear because of instant slam brake. I had to brake quick to undo it. it happen on cruise control only, also happen during auto pilot. the road was fine, other vechile wasn't going toward me.

The car brakes SEVERELY on two lane highways when passing another car. Mainly occurs when passing semi trucks. It is going to get someone rear ended if this is not fixed. The cruise control is not usable.

When the ADAS is active, during normal driving on a two-lane highway, where there is never any question of an obstruction in front of the car, the car unexpectedly and violently brakes; often the collision warning alarm sounds. This usually happens when the car meets traffic in the oncoming lane, but sometimes there's nothing else at all on the road. This is a new car (since January) and it has happened ever since I first used the ADAS. For example, last night, on a trip of about 50 miles it happened at least thirty times, nearly every time I met an oncoming vehicle of any size. Service personnel tell me this is normal behavior and they cannot do anything about it! The system is supposed to have switches to turn off the collision warming and braking so that it can be used as a normal cruise control, but setting the switches to off has no effect. This behavior is not only extremely annoying but also distracting for the driver and potentially hazardous when an inattentive driver is following closely.

Phantom braking, almost caused a car to rear end me. This was on a straight two lane road a tractor trailer was coming the other way. This has also happened on a right hand curve with smaller auto where the software thinks I'm going to run into the car even though I'm turning right into the curve. Very dangerous. Same thing happens with the forward collision warning.

Every once in a while (once per 100-200 miles) I experience "phantom braking" when using Adaptive Cruise Control with Autosteering (not sure if Autosteering matters – I always use ACC with Autosteering together, so hard to tell). That is when ACC decides to quickly reduce speed significantly for no apparent reason (no cars or other obstacles in front). It could be dangerous as it could lead the car behind me to crash into me.

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.

Autopilot and Traffic Aware Cruise Control systems are basically unusable on two lane highways. Almost every vehicle that passes on the opposite side of the road triggers an alarm, disengages Autopilot/TACC, and results in an abrupt, jarring deceleration. This occurred 10 times in a 160 mile trip, but would have happened many more times if I had not given up trying to use either system. Holding my foot on the accelerator for such a long drive was inconvenient, and the repeated sudden slow downs resulted in a strained, tired neck. It seems unethical for a $60,000 vehicle to lack basic cruise control capabilities.
