2021 TESLA MODEL 3 Complaints

When vehicle is in full self drive mode, sometimes it mistakenly detects an obstacle on the highway and applies brakes. This event presents risk of getting rear ended at high speed on highways.

Phantom braking for no apparent reason. Worst occurrence was this morning driving home from work on cruise control, max speed cruise 73mph, suddenly my car braked on its own down to 59mph in 2 seconds. Very scary. My wrist hurts from that incident & my forehead almost hit the steering. Nothing in front & thank God no tailgating car behind me. This is not safe. It happens to me all the time but this was the scariest of all.

Driving on the interstate in autopilot with nobody in front of me but there was somebody riding my rear. And the vehicle decided to phantom break which almost caused the guy to rear end me while going 75 mph it could have been lethal.

1st incident Driving on a 2 lane road @ 55MPH with no oncoming traffic emergency braking occurred (with all the warning lights and sounds) with no obstacles in my path. 2nd incident driving on a 8 lane highway @65 MPH (I-71) with very little traffic (and no oncoming obstacles) emergency braking occurred (with all the warning lights and sounds) no obstacles in my path. 3rd incident driving on a different 2 lane road @ 45 MPH emergency braking occurred (with all the warning lights and sounds) no obstacles in my path. I have only owned the vehicle 2.5 months and less the 1300 miles on the odometer.

Since my ownership, I have experienced multiple phantom braking incidents with my 2021 Tesla Model 3 Long Range. I would estimate that I experience 3 to 5 severe phantom braking incidents per week. It is nearly a daily occurrence during my daily commute to work. Sometimes there are multiple incidents during one leg of my commute. I have filed several requests for service with Tesla through their application and every time the technical support says the system is working properly. I have given them explicit details and information about the incidents which have helped them to identify the time and location but they have never fixed/changed/remedied the phantom braking issue. I have filed these requests for service to protect myself if I'm ever involved in a serious accident due to these phantom braking incidents.

While using the autopilot feature on my Tesla, there have been several instances where the car will brake suddenly for no apparent reason. This has happened at high speeds and at slow speeds under various conditions. The braking is so severe that if a car was following behind they would have to react quickly to avoid an accident. Multiple instances over the last year.

System: Traffic Aware Cruise Control Safety Risk: Full regenerative breaking in the fast lane on a highway with a car following behind. Car behind had to initiate emergency braking. Reproduced by Dealer: Did not contact dealer Inspected by Manufacturer: Did not contact manufacturer Warnings: No, braking automatically initiated System: Lane Departure Warning Safety Risk: Misreading a parking garage and initiating lane departure warning chime Reproduced by Dealer: Did not contact dealer Inspected by Manufacturer: Did not contact manufacturer Warnings: Yes, warning chime initiated and warning message.

While driving in cruise control, my Tesla 3 braked for no reason. No accident occurred because no one was behind me. It has happened about 10 times. It has not been confirmed by a dealer because I do not live near a dealer. It has not been inspected by the manufacturer, police or insurance representatives. No warning lights or messages appeared to warn me.

Driving on cruise control only. Autopilot was not engaged. I was cruising at 50mph when it "phantom" braked out of nowhere. It was clear as day in front of me and luckily the car behind me was a hundred yards or so. It abruptly decreased speed to 35mph before I could get back up to speed by manually using the accelerator to override cruise control. This has happened many times and I'm afraid to use such features moving forward.

When driving in several locations near my home, with cruise control engaged (not full driving, just cruise control), the car will suddenly slow to ~20mph and stay at that speed for a few moments, and then accelerate back up to the legal speed limit of 55mph, 60mph, etc. There are no objects on or near the road, no other cars, and it appears to be a problem with the software that identifies if there is an object in the road to automatically reduce speed or slow down. There are no warning chimes, no feedback to the driver of the reason to slow down, no posted speed limit signs, etc. I can duplicate this every time I traverse these roadways. One of the most significant reasons I purchased this vehicle was it's advertised safety features like emergency braking and such. However, with this problem, I either have to disable the auto-braking feature, or not use the driving assist features (like cruise control). This is a significant issue for me, and I have no doubt going from a 60mph roadway to 20mph for no reason will result in me getting rear-ended or at the very least cause problems for drivers behind me.
