Service Brakes problem #1

The center high-mounted stop lamp (chmsl / third brake light) fails on 2021 and newer Tesla Model S vehicles (including plaid). This is a common issue reported by many owners, particularly as vehicles exit the warranty period. No redesigned or corrected replacement part has been made available by Tesla. Pre-2021 chmsl units are incompatible and will not fit. Repair requires removal and replacement of the entire rear liftgate glass assembly, which is extremely expensive and labor-intensive for owners. Prior model years did not experience this problem. A non-functional chmsl reduces the vehicle's visibility to following traffic and increases the risk of rear-end collisions, especially at night or in poor weather. This appears to be a design or manufacturing defect affecting safety. Discussions [xxx] repair process [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Service Brakes problem #2

Incident description: while driving through a parking lot at 20 mi/hr, my vehicle's aeb system activated in response to another vehicle approaching from a perpendicular direction. However, the system's response was dangerously delayed and inappropriate stopping the car right in front of the other car: the system failed to provide any advance warning or alert before applying the brakes the braking occurred too late to create adequate separation from the approaching vehicle the vehicle stopped directly in the path of the oncoming car, increasing rather than decreasing collision risk the abrupt stop left my vehicle in a position where I was at greater risk of being t-boned only the other driver's quick reaction prevented a collision. Had that driver not stopped in time, the aeb system would have contributed to, rather than prevented, a serious accident.

Service Brakes problem #3

Recall issue for my vehicle. Have been having issues with the auto steer/auto pilot that comes in the car. The auto steer automatically goes off and whenever you make a turn, there's a weird sound.

Service Brakes problem #4

We had the adaptive cruise control, turned on and the car braked violently on I 90 in washington state heading east. The brakes slammed on so hard that the tires screeched. We were in the fast lane and it was fortunate that no one was directly behind us or there would’ve been a serious accident. It happened again about 5 miles later, but not as violently.

Service Brakes problem #5

Sudden braking while using adaptive cruise control. Multiple “phantom braking “ incidents during a long road trip.

Service Brakes problem #6

Driving midday on interstate 90 at 78 mph. The car was in cruise control. Four passengers. No other cars in front of me. Luckily there were no cars directly behind me. The car violently slammed on the brakes. My passengers thought I had hit a dog. Very scary. I am glad no one was hurt. But it is dangerous. I think the car had a recent software update. I have heard that the phantom braking issue can be worse right after a software update.

Service Brakes problem #7

Recurring uncommanded firm phantom braking for no apparent reason. At risk of being hit from the rear. Driver & passengers frightened & panicked. It has occurred a number of times but cannot be reproduced at will. Vehicle inspection has not been performed. Dealer says it's a software issue. No warning lamps, messages or any other symptom prior to event. Event has recurred multiple times.

Service Brakes problem #8

We took our first major road trip in our new 2022 Tesla Model S on Friday 10/14, leaving at 10:00 am for a 9 hour trip. During the trip the car experienced multiple severe incidents of the car braking hard while at highway speeds and two of the incidents almost caused an accident. The car drops 10 to 15 mph instantly for no reason. We drove the car home on Monday 10/17 without aeb, auto steer, fsd beta, emergency lane departure avoidance and obstacle-aware acceleration and used tacc occasionally and still had the issue but wasn't as severe. Even on the day we purchased the car (sept 30) and drove it home (a short drive on highway 95) we had a similar incident but it was so new we weren't sure if it was us or the car but now we know it is a fault of the car and creates a very dangerous driving situation which could result in an accident or death to a passenger in our car or in the car behind us when our car decides to slam on the brakes for no apparent reason. There were no warning lamps, messages or symptoms of the problem prior to the failure. We turned in a service request to Tesla and their response was to drive the car and have it happen again and create a bug report. So basically Tesla is asking us to put our lives on the line to help them diagnose the problem because they don't want to take the time to review the diagnostic data that is readily available to them. In our opinion, this is a very serious and dangerous problem and the car needs to be taken off the road until Tesla resolves the problem.

Service Brakes problem #9

The contact owns a 2022 Tesla Model S. The contact stated that while utilizing the adas features including adaptive cruise control, the vehicle unexpectedly applies its brakes while driving at highway speeds. An unknown warning light intermittently illuminated. The vehicle was not diagnosed. The vehicle was not repaired. The dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 2,236.

Service Brakes problem #10

I was driving my Model S from oregon to texas, 14-16 Sep. The car was new, picked up on 31 Aug. I had the car in autopilot when I was on the highway on the drive to texas. In the first two days I had four incidents of "phantom braking" at highway speeds, as high as 80 mph. There was not a lot of traffic those first two days and the conditions were dry so there was little risk to others and the car stayed straight during the braking. However it's not hard to imagine scenarios where unexpected braking at high speeds could be a problem, such as during wet or dusty road conditions, driving into a high speed turn with other vehicles nearby, etc. The vehicle has not been inspected but the incident has been reported to the dealer and I am awaiting guidance.

Service Brakes problem #11

While driving with traffic aware cruise control engaged and set at 55 mph the car did a hard break to an almost complete stop in the middle of the lane for no apparent reason. This occurred at least two times and both times there was no traffic in front of me. The road was a two lane highway. There was oncoming traffic and cars behind me but no cars in front of me. The breaking was so hard on both occasions and it startled me and caused me to veer off the road in the first instance . The car behind me had to break suddenly as well. After the second occurrence I disengaged the tacc as it seemed to be sensing the oncoming traffic.

Service Brakes problem #12

While on a/p cruising on the free way the car slow down and start braking on its own !!.
