Adaptive Cruise Control problems of the 2017 Tesla Model S - part 2

I experienced the "phantom braking" phenomenon while driving on freeways. It has happened 3 or 4 times in the last year or so. I did not see any obvious reason for the car to have slowed down dramatically because there wasn't a car in front of me at such instances. It occurred while autopilot was engaged. It has happened on different freeways (I-680, I-880), traversing in different directions and at different times of the day.

Additional report for same problem with different car. This report is not about a single incident, but rather a repeated problem over several years with the adaptive cruise control on 3 different Tesla cars I have owned. These cars are a 2017 Tesla s, and 2 different 2021 Tesla y models. In each case, whenever these cars are driven on a highway with the adaptive cruise control engaged, several times during each hour of driving, the cars will rapidly brake/decelerate with no action taken to cause the situation by the driver, nor any external situations with the traffic that would justify them. With the Tesla regenerative braking, these deceleration events are so extreme that it would be easy to imagine an accident with a car following closely behind. Indeed, with these situations occurring with no warning and extreme braking they are quite frightening to the passengers traveling in the car. During the most recent occurrence, I noted the exact day and minute of it's occurrence, and filed a service request with the local Tesla office. Even with the exact time of this event, the service center was unable to find anything wrong with the car. The Tesla service center attributed this issue to problems with the autopilot and full self driving software, but none of my cars have had this optional software-only the software which came standard on each of these cars. While otherwise appreciating the good characteristics of these cars, this unexplainable deceleration problem is what caused me to sell the prior 2 models before purchasing this latest model y, hoping that this problem would not recur. It is worth noting that I have owned several other make and model cars with comparable adaptive cruise control, yet this situation never occurred even once on any of these other makes of cars.

The 2017 Tesla Model S we purchased has a known issue with the mcu. The mcu rewrites information in a log chip repeatedly and has been known to burn itself out after short periods of time. Tesla has agreed to replace the mcu owners when it malfunctions, but they will only do so when the chip has completely destroyed itself and will no longer boot. Ours was malfunctioning every ~40 mins. . . All of our screens would black out while driving. Tesla refused to replace it. Additionally, we purchased full self driving from Tesla with a contract that stated "all needed equipment and software included. " this was not a true statement. Those of us with the malfunctioning mcu1 were not included in the fsd program and were forced to bribe Tesla with $2500 to update our mcus even when they were under warranty and should have been included under the fsd contract.

I have reported several comparable incidents that this recent article describes https://. . Read more...

Below is the list of dates I've emailed about issues regarding autopilot and touchscreen, and microphone issues. The first reporting of it was less than a month after purchase: 10. 19. 2017. I have all of the emails and videos (within emails) to prove all of my statements about problems with ap and the touchscreen, along with microphone issues. I can provide the spreadsheet of the data if you need it. Now that Tesla has acknowledged a problem with the e-mmc unit within my Tesla, their service center now states it is on backorder and they have no idea of when it may be available. Their most recent letter dated 3. 22. 21 states "parts to replace the vcm daughterboard on your vehicle are not yet available. " however, if I pay $1,500 for the cost of the infotainment upgrade, they can do it within a week! I shouldn't have to pay to have this fixed when there is a remedy! dates of emails and complaints about ap and touchscreen, and microphone issues, are as follows: date of purchase 9. 24. 2017 1. 10. 16. 2017 2. 10. 19. 2017 3. 12. 08. 2017 4. 12. 13. 2017 5. 12. 19. 2017 6. 12. 26. 2019 7. 04. 19. 2018 8. 05. 07. 2018 9. 05. 08. 2018 10. 05. 20. 2018 11. 08. 17. 2018 12. 09. 25. 2018 13. 11. 19. 2018 14. 02. 18. 2019 15. 02. 26. 2019 16. 03. 04. 2019 17. 04. 07. 2019 18. 04. 19. 2019 19. 04. 24. 2019 20. 05. 03. 2019 21. 05. 09. 2019 22. 05. 20. 2019 23. 07. 10. 2019 24. 07. 11. 2019 25. 09. 16. 2019 26. 12. 18. 2019 27. 01. 13. 2020 28. 03. 03. 2021 (28) attempts to resolve these issues is far more than the reasonable number of attempts to repair these defects. The first attempt was less than 30 days from the date of purchase. My Model S has been in the jacksonville, FL Tesla service center for over 50 days total. Two times I had a loaner for three weeks each.

While using the summon feature from my iphone with the Tesla application my car drove into my house causing damage. I have video of this from my camera doorbell of the incident. I work in mobile application development and was told this was user error by Tesla when it first occurred.
