2020 TESLA MODEL X Forward Collision Avoidance Automatic Emergency Braking Problems

Eil

On [XXX] at [XXX] my 2020 Tesla Model X Long Range Plus suddenly started braking while on the highway. I was driving 75MPH to San Diego from Arizona. There was no vehicles around or in front while using the cruise control. This also has been an issue with our 2023 Tesla Model Y and previous Model 3 while driving to Las Vegas at 70MPH. I really think this is safety concern. Luckily there was vehicles behind us with all incidents that took place. I recently took the 2020 Tesla Model X on [XXX] for the issue and the technician found no issues while driving it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Brakes will lock up a pre collision will activate in forward and reverse when no objects are present. It is a hazard to operate the vehicle since it will randomly slam in the brakes will driving down the road or reversing out of a parking space. Also electrical issues vehicle will no longer lock or unlock

Many hard braking incidents Ignores posted speed limits Been close to being rear ended by following cars

I drive a 2020 Tesla Model X long range plus. I bought it new and now have about 50,000 miles on it. Over the years, I have experienced quite a few phantom breaking incidents when the car was in auto pilot (self steering mode). Most of these were fairly minor in nature and not much of a concern. This July I drove the car to Colorado and back and had innumerable severe phantom breaking events. In the past the breaking would be fairly gentle and a tap on the accelerator would return the car to the preset speed. In July, the car was essentially “slamming on” the brakes and required an aggressive press of the accelerator to disengage the breaking. It felt like the car was going to come to a stop in the middle of the highway. I was cruising about 70 mph and would say that by the...

On multiple occasions (between 6 and 10) while driving east and west on interstate highway 80 between Reno and Salt Lake City the vehicle executed a phantom braking maneuver while autopilot was engaged. I was east bound on 2/2/23 and 2/24/23 and west bound on 2/7/23 and 3/5/23, i.e., these events occurred on multiple days in multiple locations. On no occasion was there any danger of collision with another vehicle or other obstacle. In fact, the braking was most likely to occur as my vehicle topped a rise in the highway followed by a gental downgrade with no other vehicle or turn in the road for at least a mile ahead. The braking was very hard and caused my vehicle to slow by at least 10 mph before I could react. On one occasion, I immediately accelerated to return to the posted highway speed of 80 mph and the vehicle...

Tesla model X is infamous for its acceleration shudder. they have replaced the drive shafts twice already. when you accelerate the wheel vibrates only between 15-35 mph. When you brake hard it does the same thing.

I have experienced several issues with my car: It brakes suddenly for no reason in the middle of the freeway It displayed an error message that said the right rear seat safety system has failed and needs service It displayed an error message that said the ultrasonic sensors are not communicating with each other (I believe these are used for the driver safety systems). I reached out to Tesla asking to look into these issues. Each time Tesla denied service and asked me to note down the exact time that these issues happened to help them investigate (they specified the format with an example 06/20/2022 5:22PM PST). If I’m driving the car, how is it safe for me to note down time with this precision? Also, the car has functionality to record all of these alerts but Tesla’s software updates wipe them out (instead of retaining them). Further, Tesla asks...

Recurring Phantom braking every drive

When I'm using the driving assistance on the highway, and I'm doing like 60 or 70 mph, all of a sudden the car brakes to 45mph if it (falsely) thinks we are in a construction zone I believe. I have almost gotten in 3 accidents because the car suddenly brakes hard on its own, without me braking.

When using any driver assistance function (autopilot, adaptive cruise control, or autopilot with navigation), phantom breaking is common and terrifying. I am scared to use the systems now because of how unpredictable phantom breaking can be and how jarring (and unsafe it could be) when it happens.

While idling in drive having applied my foot to the break, the dash displayed H for holding the break. My car accelerated by itself forcefully into the vehicle in front. My seat belt did not lock up, air bags did not deploy, emergency braking didn’t work, the Tesla box report does not match the dash cam timeline. This was sudden unintended acceleration and I pray it doesn’t happen to anyone else.

1) Cruise control randomly resets itself to different speeds. Happens several times daily. I can set it to 55 and 5 seconds later it will reset itself to 80 and accelerate suddenly, or vice-versa. It can change to any speed-either higher or lower than what I've set. Happened yesterday afternoon (3-17). First noted it being a problem 2-28 at about 6 pm MST while driving on 4 lane highway in Colorado, with multiple episodes of randomly resetting speeds itself. Given the rapid acceleration/deceleration of a Tesla, when the cruise control resets itself, the acceleration/braking can be abrupt and significant. 2)Ghost braking has been and remains a problem with this car. It was serviced by Tesla 2-18 and a "chip" was replaced per Tesla. I reported about a dozen incidents of ghost braking to Tesla shortly after picking it up but don't have exact times/days. There are 3 episodes of ghost...

Vehicle randomly breaks hard when either in cruise control or auto pilot. Either on normal highway lanes or in the diamond lane. Happens frequently - at least weekly on local Southern California Hwys

While on autopilot or cruise control, the car would suddenly and abruptly slam on the brakes for no reason. There's no traffic or objects to avoid. It was very startling because it could have caused a massive rear-end collision had I not intervened to cancel the autopilot and speed up again. . Because of this, I have stopped using the autopilot feature altogether. I cannot trust it will work properly. I have mentioned it to Tesla and they simply say the software update will solve it. It has not!
