2018 TESLA MODEL S Complaints

The contact owns a 2018 Tesla Model S. The contact stated while driving at 65 MPH with cruise control activated, the vehicle inadvertently started braking and the cruise control disengaged. There was no warning light illuminated. The contact stated that there was no other vehicle nearby. The vehicle was driven safely to the residence. The failure was intermittent. The vehicle was taken to the local dealer to be diagnosed. The contact was informed that an unnamed software update needed to be performed. The vehicle was not yet repaired. The manufacturer was made aware of the failure. The failure mileage was unknown.

I have experienced many times "phantom braking". When I reported that to a Tesla service center 2 years ago, they did not know of this problem. It is scary and dangerous especially for the cars following me It only happens to me on the freeway when in ADAS mode. There is a exact place on the 5 freeway SB near Disneyland, that each time I drive there, phantom braking happens. Further also random without noticing any reason for it.

Phantom breaking. Car Suddenly breaked on highway going at 70 miles per hour. No crash. This has happened 5-10 times over the last year

Operating vehicle on highways while utilizing Autopilot and/or Autosteer(FSD) braking will randomly occur without any warning. This is commonly referred to as “Phantom Braking.”

I purchase a used 2018 Tesla Model S about two months ago. Braking is very "jerky, causing me and my passenger to "lurch forward" unnecessarily. I run into this "phantom braking" issue numerous times every time I drive. It happens both on Automatic Cruise Control and FSD and under different circumstances" and encompasses: (1) Sudden braking for no apparent reason; (2) Sudden braking that is unnecessary or is too forceful for the circumstances; (23 If the car is on automatic cruise control or FSD, it will slow down and stop too far away from the car in front. So, I push the accelerator to close the gap. When I left my foot off the accelerator, the software apparently thinks it's too close the car in front, and jams on the brakes unnecessarily. Also, when on automatic cruise control, if the car in front of me goes around a curve and then shortly thereafter stops a stop sign/light, my car, sensing that the coast is clear, will accelerate to the speed limit. as it approaches the curve, which it should not do. Then, when the car in front suddenly comes into view, my car will have to "jam on the anchors" in order to stop in time. While I'd rather be "safe" than "sorry," the degree of this phantom braking should be addressed.

This incident happened some time ago but I read recently about complaints related to "phantom braking" which I also experienced. I was driving on the highway at speed with my cruise control activated. There was no traffic close in front of me, but a large semi was in the lane to my right. This vehicle triggered sharp braking of my car. It was very scary, but I immediately overroad the braking to avoid being hit by a vehicle behind me. I have never used my cruise control since that incident.

Without warning, the car will phantom brake at highway speeds at least once or twice on every highway trip I take. It will slam on the brakes automatically even though nothing is in front of the car, putting us at risk of losing control or a rear end collision if someone is following closely. This has been happening since I purchased the car in 2018 until I sold it in late 2021. Tesla cancelled my mobile service appointment about this issue, saying this is "normal environmental conditions" without even looking at the car. I have since sold the car due to this issue and frustration with their response, but wanted to report the safety issue here.

While driving at approximately 40 MPH the car suddenly braked by itself! A sound alarm and display indicator were also activated. After a couple of seconds the event resolved without any intervention. Their was no warning lamps or messages prior to the event. At the time I was driving on a divided road and there was light traffic at the time. The car was not on cruise control or auto-pilot. My concern was being rear-ended by the vehicle behind me! The car has not been inspected by anyone since the event.

Recently saw an article that NHTSA was looking into "Ghost Breaking" with Tesla cars. This is something we have experienced with our Model S on a few occasions in 2018 and 1029. Haven't been driving that car that much now during the pandemic. Problem reported to Tesla: While driving on US 101 in Bay Area (driving from Milpitas to South SanFrancisco), and the car on Adaptive Cruise Control, the car would suddenly break and resume driving again. This not only scares the driver, but could be very problematic in a crowded lane. Telsa has looked into it when we complained and there was not definitive answer or fix. Hope the recent considerations by NHTSA will result in a through root cause and corrective action. Thanks!

Driving on a freeway at 75mph with autopilot turned on, the car suddenly braked, requiring manual intervention to accelerate to intended speed. After this the car continued as normal. There was no visible obstruction. Fortunately I have had this happen while a vehicle has not been behind me otherwise there is a possiblity of a crash.
