Vehicle suddenly stopped on highway luckily there were no drivers behind me. The vehicle all of a sudden started beeping even though there was a clear path and no obstructions. Then stopped. I was panicked and in awe at what was happening. I couldn’t get the vehicle to drive I was just stuck for 10-15 seconds. I was finally able to get the car moving again but the problem hasn’t happened since. Any information as to what may have gone wrong may help other Tesla owners who may or may have not experienced this… yet.
On Dec. 26, 2023, at approximately 6:30 pm while I was driving my 2019 Tesla Model S in fort lee, NJ. While navigating through congested traffic and executing a right turn from bridge plaza north to lemoine avenue south on a green light, the auto-pilot system was not using, my vehicle unexpectedly experienced sudden acceleration. Despite my immediate attempts to pump the brakes, the car failed to decelerate, resulting in a collision with a small bus at its rear side. Subsequently, the car continued at full speed, colliding with three additional vehicles before finally coming to a stop. Under such impact, no air bags opened. I would greatly appreciate further investigation and assistance in understanding the cause behind this sudden acceleration, as it not only endangered my safety but also resulted in damage to multiple vehicles. I do have a police report but cannot upload to this report, please let me know how to submit the report (fort lee police dept. Incident # I-2023-073265).
Driving on autopilot on the highway, the car suddenly brakes with not apparent reason.
The contact owns a 2019 Tesla Model S. The contact stated the experienced phantom braking without warning while on cruise control at approximately 76 mph. The vehicle's speed then reduced to approximately 45 mph. The cruise control eventually began functioning as expected increasing the speed back up to 76 mph. The failure occurred twice within 20 miles of each other. The first time there were no other vehicles nearby and the second time occurred shortly after passing another vehicle. The dealer was made aware of the failure however they were not able to duplicate the failure. The vehicle had not been diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 24,500.
With increasing frequency in recent weeks, my Tesla brakes without warning. It seems to occur while under adaptive cruise control. At times the car is approaching a road sign. At other times there is no reason apparent to me. The adaptive cruise control works well otherwise.
The contact owns a 2019 Tesla Model S. The contact stated while driving at 70 mph on auto pilot and the vehicle braked on it's own with no warning. The contacted stated that he had to accelerated causing the vehicle to operate normally. The contact stated the failure reoccurred without auto pilot on the vehicle. The dealer or the manufacturer was not contacted. The failure mileage was 59,000.
This is my 6th trip with 2019 Tesla s from chicago to san francisco / 1st time so many “phantom braking” incidents / flat tire warning error / screen shut off 3 times …. .
Repeated unexpected emergency braking incidents, similar to those described in the recent washington post article. The first one happened on the day that I bought the car, and has never improved. One scenario is the same as described in the article - oncoming car/truck on a two-lane road. But it also happens on freeways. If cruise control is on, it's likely that there will be at least one event during a 30 minute or longer session. As others have mentioned, these are often in congested traffic. When a car is following closely, they have to react very quickly. In several cases they have gotten angry because they think I'm slamming on the brakes to discourage them from tailgating. The very first incident, on the day I bought the car, was hair-raising. The car slammed on the brakes in the middle of an interchange where a semi was close behind and there was dense traffic all around both of us. Fortunately the driver was very alert and avoided me without endangering anybody else. But things could have gone the other way. I've mentioned it to local Tesla service people who (at the beginning) said that the car was in the learning period, calibrating the sensors. The user documentation mentions this and suggests that the training interval could be as much as 100 miles. It gets worse and better as Tesla fiddles with the software. It did indeed get quite a bit worse with the release of the full self driving beta -- which I have qualified for but never actually used because. . . Heck, if they can't get cruise control right, I sure don't want them to take on any more responsibilities.
