What 379 owners told NHTSA about the 2017 Tesla Model S 75d

When in Full Self Driving mode, on the highway going on an overpass.... the vehicle suddenly applies the brakes. Imagine going from 70 mph to 40 for no reason. I discussed with Tesla, they said the vehicle is reading the speed limit from the road below the overpass. Very unsafe.

My Tesla suddenly brakes, without any input or action by me, on the highway without warning causing me to take corrective action to avoid being rear ended. My wife refuses to drive with me. She feels unsafe in the car. I have submitted complaints to Tesla multiple times. The frequency of sudden braking has decreased but it still exists

While driving on the highway at 65mph on autopilot, the car brakes very aggressively without any obstacles obstructing my path. Clear road ahead and I got from 65 to 50 very quickly and for no reason. I won't accelerate back to 65, but again the car was aggressively braking me back down to 50mph. It begins to look like in brake checking the driver behind me and they become upset and drive aggressively around me. This has happened so many times, I've lost count. I'll fill out a single incident report, but this has been happening for the past couple of years. I know you guys are getting a lot of complaints about this issue so I wanted to let you know about another vehicle having the same problem.

While on I65N, traveling at full speed on cruise control but not auto drive, the vehicle automatically applied the brakes. There was no apparent reason to brake. There were no cars in front or to either side and nothing on the road. We slowed quickly and abruptly, throwing everyone in the car forward. The slowing was so fast and so extreme that we were almost rear ended by the semi behind us. If he had not been able to move partially into the right lane and us into the left, he would have hit us at 70 mph. This is not the first “phantom braking incident ” that we have had but it definitely is the most dangerous one.

The contact owns a 2017 Tesla Model S 75. The contact stated that while driving at approximately 70 mph, the brakes were seized while on autopilot. In addition, there was a warning error the contact was unable to remember. The contact mentioned the emergency brake engaged independently and the contact was unable to control the vehicle which caused the vehicle to crash into the guardrail. A police report was not filed. The air bags failed to deploy. The vehicle was towed to a service center where a diagnostic was not attempted but the vehicle was repaired. The manufacturer was notified of the failure. The VIN was not included in NHTSA campaign number: 21v846000 ( forward collision avoidance). The approximate failure mileage was 54,504. Vehicle was not listed on the recall.

MY TESLA MODEL S HAS THE V1 HARDWARE, ALSO KNOWN AS MCUV1, WITH THE DAUGHTERBOARD EMMC REPLACEMENT FROM THE PREVIOUS RECALL RUNNING ON FIRMWARE 2020.48.37.1. THE SOUND FOR THE ENTIRE CAR WILL CUT OUT. IT MIGHT COME BACK, BUT EVEN A REBOOT OF THE CAR DOES NOT SOLVE ANYTHING. THESE SOUNDS MAY INCLUDE BLINKER NOISE, SPEED LIMIT CHIMES, LANE DEPARTURE WARNING, AUTOPILOT ENGAGE/DIS-ENGAGE CHIMES, GEAR WARNINGS, COLLISION SAFETY CHIMES, EARLY BRAKING WARNING, AND A LOT MORE SAFETY-RELATED SOUNDS. THIS HAPPENS EVERY TIME I DRIVE THE CAR, NOT JUST THE REPORTED DATE. I HAVE BROUGHT IT IN FOR REPAIRS NUMEROUS TIMES, BUT THIS HAS NEVER BEEN ADDRESSED. I AM ONLY TOLD TO WAIT FOR A NEW FIRMWARE UPGRADE, WHICH I HAVE BEEN FOR YEARS NOW SINCE I FIRST REPORTED THE ISSUE TO TESLA. THIS ONLY HAPPENS WITH MCUV1 CARS AND THEY HAVE REFUSED TO PROVIDE A FREE HARDWARE UPGRADE EVEN AFTER MY INCESSANT REPORTS AND APPOINTMENTS STATING THAT IT IS UNSAFE.

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.

A PHANTOM EMERGENCY BRAKING EVENT OCCURRED TWICE ON MONDAY, DECEMBER 21, 2020 WHILE DRIVING FROM DALLAS TO HOUSTON BETWEEN THE HOURS OF 12PM - 4PM CST. I ALSO EXPERIENCED THREE BLANK SCREEN EVENTS DURING THIS SAME TRIP. THE MEDIA CONTROL UNIT (MCU) CONTROLLING THE MAP, RADIO, AIR CONDITIONING, BLINKER SOUNDS ALSO CEASED OPERATING. THE SECOND OCCURRENCE OF BOTH THE PHANTOM EMERGENCY BRAKING AND BLACK SCREEN EVENT OCCURRED ON SATURDAY, JANUARY 9, 2021 SHORTLY AFTER 10AM CST. THE SUDDEN PHANTOM EMERGENCY BRAKING EPISODE I EXPERIENCED AT HIGHWAY SPEED FROM DALLAS TO HOUSTON WAS EXTREME. I SIMPLY DO NOT FEEL SAFE USING THE CRUISE CONTROL OR AUTOPILOT IN THIS VEHICLE. SOMETHING IS VERY WRONG. HOWEVER, TESLA MESSAGE TO ME STATES 'WE ARE HAPPY TO REPORT THAT YOUR HARDWARE VITALS FOR THE MEDIA CONTROL UNIT AND EMMC ARE IN GREAT SHAPE AND DO NOT REQUIRE REPLACEMENT'. I HAVE ATTACHED A PRINT SCREEN OF THIS MESSAGE.

BROUGHT THE CAR IN FOR SERVICE AT THE MACADAM SERVICE CENTER IN PORTLAND, OREGON ON OCTOBER 29TH DUE TO MCU ISSUES; THIS WAS BEFORE ANY NOTICE HAD GONE OUT! I WAS NOT EVEN AWARE OF THE ISSUE AT THIS TIME. IT WAS REBOOTING, VERY SLUGGISH, GETS 'LOST' IE KEEPS OUTDATED INFORMATION ETC. THIS IS OBVIOUSLY THE 8GB MEMORY DEVICE ISSUE. AFTER A 40 YEAR CAREER AS AN ENGINEER AND VENTURE CAPITALIST IN THE IT INDUSTRY I KNOW WHAT MEMORY FAILURE LOOKS LIKE! I WAS TOLD THERE WAS NO ISSUE AND THAT IT WAS SAFE FOR ME TO DRIVE TO SF THE NEXT WEEK. I HAD MAJOR ISSUES ON THE TRIP. THE SYSTEM REBOOTED A NUMBER OF TIMES, WAS EXTREMELY SLUGGISH AND HAD DATA UPDATE ISSUES. SPECIFICALLY: -DEPART LAKE OSWEGO AT 5:30AM ON 11/23. SOON THEREAFTER THE LEFT FRONT FENDER CAMERA INFORMS ME IT IS NOT WORKING. IT DOES SO REPEATEDLY EVERY MINUTE OR SO FOR A LONG TIME. THEN ALL CAMERAS INFORM ME THEY ARE NOT WORKING. I STOP, TWICE, CLEAN ALL THE CAMERAS AND IT DOES NOT RESOLVE ANYTHING. I GIVE UP ON THE CAMERAS WORKING AND STOP USING CRUISE CONTROL -AT 12:31PM IN THE SHASTA AREA STREAMING FAILS AND THEN THE WHOLE MCU SHUTS DOWN. WHILE DRIVING IN THE RAIN I AM FORCED TO REACT AND OPEN WINDOWS TO KEEP THE WINDOWS FROM FOGGING UP WHILE DRIVING AT 70MPH. OTHIS IS A SERIOUS SAFETY CONCERN. I HAVE UPDATED MY NHTSA COMPLAINT TO INCLUDE THESE SERIOUS SAFETY CONCERNS. -7:48PM 11/23, WHILE SUPERCHARGING IN EMERYVILLE THE MCU COMPLETELY FROZE. I WAS HAD TO FORCE A REBOOT. 2ND REBOOT IN ONE DAY -5:28PM 11/24 MCU CRASHES WHILE DRIVING AGAIN! HOW DO YOU NOT UNDERSTAND THE SAFETY IMPLICATIONS OF THIS?! THIS IS THE 3RD CRASH IN 2 DAYS!. I WILL MAKE AN APPOINTMENT AND EXPECT YOU TO FIX THIS ISSUE. I WILL CONTINUE TO UPDATE MY NHTSA COMPLAINT REGARDING THESE SAFETY ISSUES UNTIL TESLA RESOLVES THEM.
