Assist Problems of Tesla Model S - part 2

I was driving north on I-5 in san diego, in the right hand lane at 11:37pm, at 70mph with the fsd autopilot engaged. Approaching a gentle left hand bend in the road I spotted a disabled vehicle in the right shoulder with its hazard lights on and the driver door open. The car was fully off the road and was not a hazard. My car suddenly applied the brakes and did a weird “shimmy” as if it was trying to decide to make a turn. The autopilot did not disengage. My hands were on the wheel the whole time so I immediately took control and disconnected the autopilot by pulling up on the bottom-left control column stalk. The autopilot relinquished control as expected. I have not experienced any previous incidents of random autopilot braking on the freeway. This particular incident did not create an unsafe situation but the sudden braking did startle me. I tried to use the vehicle’s voice recognition system to file a “bug report” right after but it didn’t work.

My Model S routinely experiences "phantom braking". I'm driving down the freeway with the Tesla "autopilot" engaged and it momentarily hits the brakes, usually slowing 15-20mph before it either it recovers or I intervene. I've also experienced "phantom braking" with just the traffic aware cruise control engaged and not the "autopilot".

I have used the self driving feature of my 2022 Tesla Model S on several highway trips, most recently a round trip between seattle and palm springs. The following problems with the Tesla self driving feature were noted. (my car has only the basic self driving feature, not the full self driving upgrade) 1. Random “phantom braking” where the car, without apparent reason, suddenly braked. 2. On several occasions the car abruptly swerved off toward an off ramp. I think this occurred when the white line marking the side of the road was interrupted by the off ramp where there was no painted line. 3. On several occasions when the turn signal was activated in order to change lines the car started to move over into the adjacent lane but abruptly swerved back to the original lane. I was able to maintain control but it was a frightening event. Due to the unpredictable nature of these events I greatly reduced my use of the fsd feature.

During placing the car in highway autopilot mode by clicking the stalk twice the car made a hard right turn that I had to correct manually until the auto drive dropped out. On a separate occasion, in autopilot, the braking system was applied when there was no reason. On another occasion, in autopilot, the car went out of the lane over the yellow line. I took the car to a Tesla service center where I was told that my mcu1 needed to be replaced with a mcu2 at my expense at $1610. There currently is no recall for the failure of the mcu1 that controls the autopilot functions. Other symptoms are screen blackout. Seat loss of position sync, slow navigation commands.

Since Tesla has disabled the radar, and went to vision only, my car is a nightmare to drive on autopilot or fsd on two lane roads at night. Phantom braking, numerous times it has went onto the shoulder thinking an oncoming car a 1/4 away was in our lane, twice it even went into the oncoming traffic lane. Never did this when radar was enabled. My car has radar but they turned it off in software update.

Mcu will not keep up with basic standard features. Map would not load mid trip causing autopilot to fail during a turn causing car to veer wide and almost crash into a wall. Advised Tesla service and they said the only fix is to spend $2000 to upgrade the mcu.

Beta autopilot was engaged, driver had hand on steering wheel, vehicle was traveling less than 35mph (speed limit) and coming around a corner when it misjudged the road curve. The road curved to the left and as the car took the turn it took too wide of a turn and veered slightly off the road. Unfort the front right side of car went up and over the begining of a rock incline. The front right tire blew out and only the side airbags deployed (both sides). The car traveled about 500 yards along the road and then turned itself off. I could not get the horn to work, nor put it in neutral. There were no warning signs before incident. In fact the I belong to a beta driving scoring rating and for that day Tesla rated me a 91/100. I called Tesla roadside assistance and they said they would not provide any help as it was viewed as an accident and not a self-driving issue. It was reported to Tesla and I have called several times to try and understand why the car didn't stay in the lane and why only the side airbags deployed. I reported this to Tesla customer support and was now told they would not provide any information based upon their analysis, although initially I was told that it would take 5 weeks for engineering to review and get back to me. Vehicle is at repair facility and was told damage to car will be almost $28-30k. Car previously had issues with forward collision warning system going off, although I was not aware there was a recall regarding this exact problem, back in October 2021.

On Nov 14 at 09:01 am while driving on the freeway with clear weather and autopilot is on for at least 15 min and and I am fully attentive and no traffic the Tesla auto pilot decided to turn left and hit the cement barrier of the freeway damaging my left rear wheel then it tried to correct it fault by turning right to the right lane abruptly luckily there was no traffic coming on my right side too otherwise it would have been fatal I have the incident recorded by the sentry mode cameras and exact time and sec and the logs of the car black box proves that the Tesla auto pilot was engaged at that time when it hit the cement barrier I reported this to Tesla so they would take responsibility of their risky autopilot software but they dont care and told me I can report it to NHTSA it doesnt matter to them even with all the documented proof I have.

I have been complaining since I got this Tesla in late 2017, that the car brakes unexpectedly on the freeway. Tesla claim that nothing is wrong & this will happened if the sensor received a signal like light from another car, but I was driving on the freeway during daytime? on 10/31/21 while driving autodrive on the freeway the car suddenly skid to the right twice, around 6. 50 pm & 9. 05 pm. My grandson was in the car with me and witness the incident. Luckily I was able to straighten the car without any accident. Tesla made an appointment for a mobile visit on 11/5/21, but cancelled on 11/4/21 and reschedule one month later on 12/9/21 to a service ctr in walnut. This is a safety issue and Tesla is not seriously taking care of.

The car thinks the trunk is open but it is not. As a result, the car doesn't stop beeping as a warning to a trunk that is fully closed. In addition, I can't open the trunk at all. When driving the car I can no longer use autopilot and other safety features of the car. I also can't lock the care. All and all, the car in unusable, because of an issue with the trunk, this is definitely a faulty design.

At ~5,000 total vehicle miles, our 2019 Model S performance had sudden and complete power steering assist failure at highway speeds, possibly concurrent with autopilot (autosteer) failure. Either I, or the autopilot system, turned off the autopilot feature at or near a slight curve on an interstate freeway. Immediate "startle" reaction was that the autopilot feature was "fighting" me for control as I turned the steering wheel to keep the car on the freeway, with extreme effort. The reality is most likely that this "fighting" was only the immediate impression caused by the massive amount of effort required to turn the steering wheel, despite being at speeds in the 60-70 mph range. Soon noted a scrolling series of warning messages: a. "steering assist reduced: steering may require increased effort. " [which is a gross understatement. ] b. "autopilot safety/convenience features unavailable: features may be restored on next drive. " [which, after the car had sat parked for ~30 minutes, were restored. ] user-visible mcu-display failure log revealed the following supplemental failure codes (with the probable times of failure):: 1. 17:26/app_w207: autosteer temporarily unavailable 2. 17:20/app_w264 autopilot safety/convenience features unavailable: features may be restored on next drive I feel very strongly that this sort of power steering failure would likely have resulted in a less experienced driver suspecting the steering had "locked up" and be causal to a major accident. Given the circumstances of the failure mode, and at these speeds, fatalities could be likely. Of note, this is at least the fourth time this has occurred to us, but the first with this car; all other events were in a 2017 Model S performance, also at very low total mileage. After a failed repair attempt, that Model S was traded in to Tesla for this Model S . . . .

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.

Tesla Model S 2015 90d. I have a service appointment come November 30th 2020 for this but I have had multiple occurrences of the main panel and side panel display go completely crash and black screen on me. Disabling both the "autopilot" v1 feature in mid use on a highway going 60+ mph, gps and other important assistant information such as vehicle speed etc(because screens are black). Its a very jarring and dangerous experience going fast on the highway and having the car "crash" in such a way that just gas and breaking are all that are suddenly left working in an instance(especially when you have that auto pilot feature engaged on a turn). I strongly recommend NHTSA to continue their investigation towards this as there are likely serious flaws with the emmc system and software these early Model S cars released with. I am afraid Tesla is going to give me the run around and not handle the situation appropriately, which would generally be a consumer recall when events as dangerous as this occur. I would say these full system crashes have occurred at least 5+ times since I have owned the car in 2015 and it seems like a matter of time before a serious crash could be caused by this faulty engineering . Tesla currently is trying to do as much damage control around it offering to look into a replacement part but no guarantees its covered by their warranty. As a software engineer myself it feels very much like when hardware starts to go bad, like a system internals beginning to fail due to corrupt memory and storage. These early Tesla Model S'ES are a ticking time bomb to public roads(I say this as a Tesla fan, when working the cars are incredible to drive, when they dysfunction its a very serious problem because of the nature of these software driven vehicles their hardware/software has to be rock solid).

My front suspension failed, causing a wheel misalignment and uneven tire wear. The control arms and the suspension ball joints failed, causing the driver's side wheel to be loose. I have kept the parts and the expensive repair bill. It appears that the rubber gaskets failed and water entered the joints causing premature wear. With the lane keep (autopilot function) on highway 40 between lawrence and topeka, the car steers itself either toward the ditch or toward oncoming traffic when approaching the top of a hill. It is very dangerous. 10.

Prior to 10/2/2020 numerous reboots usually after being parked. Had to wait excessive time since I had pin to drive enabled. Disabled pin to drive since I was getting stuck. It is embarrassing and not a good reflection on Tesla products to have to wait 5 minutes to move your car. Something is wrong. 10/2/2020 while driving on I 40 noted there was a lack of turn signal sounds. Noted navigation did not seem to be updating to current position. While on autopilot the car started to drift toward an exit. The autopilot had disengaged with no warning sound' nothing. Continued to steer manually. Screen went black. Ac stopped. After several minutes the screen rebooted. Had to re-input destination. 10/3/2020. Went to ashland nc supercharger to top off before getting on the blue ridge parkway. Was only getting 4 kw to start finally giving up after 30 minutes achieving a maximum of 10kw. When I unplugged I got a warning "reduced power, systems shutting down. Service required. Vehicle may not start". The screen went black and after time finally restarted and I was able to continue. Later in cherokee nc the screen again rebooted after charging at a j1772 station. 10/4/2020. While driving with on i95 near st augustine I noted the loss of turn signal sound again. The navigation was frozen again. Again there was no sound or warning disengaging or engaging autopilot. The screen went black. The ac went off. I observed the Tesla t come up then the screen went black again. Then the Tesla t came up a second time and after several minutes the controls started working again. Again at Nov 19@ 7:03 driving west in I-4 stanford, FL. Same as on 10/2. Loss of autopilot, loss of turn signal sound, loss of climate control, loss of music. Took 6 minutes to reboot. Took an additional 5 minutes for navigation to restore. There are more instances but I am out of characters.

8:15 am, 6/19/20, I head a sickening thwack from the street from abt 300 yds away. Eerily, bec something very large was hit with no sound of squealing brakes or cries, I went out front to look left without seeing anything. Then I looked right and saw a man crouched to the ground beside a car. I iooked further rt & saw the back of a man thrown face-first into my trees. I didn't imme register what I was looking at until I recognized the body as my husband, screamed, & ran to him. He was snoring loudly. I was afraid to touch him, so I hovered over him calling his name. He did not respond. I turned to the street, screaming at passers-by to call 911. The crouching man said he had, but I was fearful of him & thought, "how do I know you have? why are you so far away? didn't you even come over to check on him?" I kept screaming as drivers stopped their cars and people gathered. Our 19-yr-old daughter came running out of the house, followed by our 17 and 15-yr-old sons. An ambulance came and took my husband, refusing me because of covid. Then I spoke with 1 of 2 police while the other spoke to the driver of the Tesla. He said the driver admitted to being on his phone as the car drove itself, never seeing my husband and driving 45 mph. When he said I could leave, I went to the er where I was imme told my husband had sustained severe brain damage to both sides of his brain and catastrophic other injuries. A police investigator met me at the er. Investigation of the vehicle & download of the computer were completed at police station. I was told the Tesla had been in 1 prior ax, but had not registered "an event" on 6/19. Lawyer present did say the car was in "autopilot" & sev systems had malfunctioned: airbag, braking, warning sound, veering away, etc. I was later told he was doa, but brought back. 10 mos later, husband is a non-communicating quadriplegic, severe tbi, feeding tube.

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.
