2019 Tesla Model 3 driver assist problems

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

Tesla rolled out FSD 14 Lite to hardware, including to my vehicle and it’s become extremely unsafe.The past several days the vehicle will suddenly slow down/break causing people to almost crash into me, make sudden and indecisive lane changes, and constantly rocking the steering wheel left and right. I hope someone takes this seriously and has Tesla revert back to the old software or make changes before someone is killed.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

I was using Full self driving (FSD), but I notice the autopilot gets "impatient" when (correctly) stopped for a "long" period of time (~2 minutes), but will then try to proceed in dangerous conditions. 1. I had FSD engaged while waiting to make an uncontrolled left turn. The street I'm turning onto is busy, so both lanes are going at a steady pace. After about 2 minutes of waiting, the autopilot decided to make the left turn while BOTH directions had cars approaching. It turned towards a motorcyclist (which might be why it thought the lane was "empty"), and cut off a rather large car behind the motorcycle which almost caused a collision. I was honked from both sides (rightfully so) and put in a very dangerous position as my car was now stopped in the middle of the row of both lanes. 2. I was at a red light intersection with no traffic coming from either side with FSD engaged. After about 2 minutes of waiting, the car tried to go on its own while the light was still red. After manually stopping the autopilot, the light naturally turned green a few seconds later.

The contact owns a 2019 Tesla Model 3. The contact stated that while the vehicle was parked, the rearview camera became inoperable while opening the trunk. The message “Camera Not Available” was displayed. The contact stated that the rearview camera functionality returned after opening and closing the trunk several times. The vehicle was taken to the dealer, where it was determined that the rearview camera wiring harness had failed and needed to be replaced. The vehicle was not repaired. The contact informed the dealer that the vehicle had previously been associated with a recall related to the failure; however, the dealer did not repair the vehicle under the recall. The manufacturer was made aware of the failure. The approximate failure mileage was 81,952.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

What component or system failed or malfunctioned, and is it available for inspection upon request? The steering system failed due to corrosion and water ingress affecting both the steering rack and the associated steering wiring harness. These components were replaced by Tesla and are no longer available for inspection. How was your safety or the safety of others put at risk? The steering system is a safety-critical component. Corrosion and water intrusion created a risk of reduced or sudden loss of steering assist while driving, which could lead to loss of vehicle control and increase the risk of a crash. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Tesla service confirmed water ingress and corrosion affecting the steering rack and wiring harness and performed a full replacement of both components. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. The vehicle and steering components were inspected by Tesla at a Tesla Service Center, which identified water ingress and corrosion as the cause of failure. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The vehicle displayed steering-related warning messages prior to repair, including reduced steering assist alerts, which prompted inspection by Tesla service. The warnings appeared shortly before the repair was performed.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

My vehicle was working fine when Tesla issued an over-the-air software update recently. The next day, my backup camera was not working. The back up camera is required for this vehicle under FMVSS 111 and is otherwise essential for this vehicle due to limited rear vision through the rear window. In addition, GPS/navigation stopped working, the windshield wipers did not function on certain settings and the display was at times not legible, presumably because it believed it was a different time of day and was in the wrong mode. There are likely additional issues that have not revealed themselves yet. I took the vehicle to the local Tesla Service Center on July 25, 2025. They confirmed the reported issues and said it was a problem with the software update, which they would perform onsite while I waited. The service center personnel also stated this was not a firmware issue or anything to do with my car and that it was just the software update. After a few hours, the personnel reported they could not get the update to install and asked that I bring the vehicle back the following week for further diagnostics. Before I brought the vehicle back, I was sent an invoice for approximately $2,300 for replacement of on vehicle's computer. I brought the vehicle back today, July 29, 2025, and asked them to perform the onsite diagnostics they wanted me to bring the vehicle back in for and did not agree to pay for the computer replacement. I also informed the Tesla personnel that, at a minimum, the the back up camera failure is a safety related issued covered for this vehicle under FMVSS 111 and that they were not permitted to charge me for fixing it. The vehicle warranty period recently expired but it is well within the 10-year date of manufacture. Other issues with the vehicle may also qualify as safety related, but the back up camera is clearly one - Tesla recently issued a recall for this very same problem impacting the Model 3, but the recall did not include my model year.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

The rear camera on my Tesla intermittently fails when shifting into reverse. Additionally, the rear trunk will not open using the in-car release button, mobile app, or key fob. A warning appears stating the function will return on the next drive, but I am often forced to use the emergency release to access the trunk. I believe this may be related to a prior recall involving the rear trunk harness, but when checking my VIN, no active recalls appear. Tesla service also reports no recalls on file. I am also receiving an intermittent fault message regarding the front passenger safety restraint system, stating that service is required. This is a serious concern, as a malfunctioning restraint system may fail to protect occupants in the event of a crash. Tesla has given me an estimate of $225.00 to address the safety restraint fault and $495.27 to repair the trunk/rear camera issues, with a total cost of $739.60 including taxes. I believe that safety-related repairs, especially those involving airbag and restraint systems, should be covered by the manufacturer and not passed on to the vehicle owner when not due to misuse or damage. The passenger restraint fault poses a direct safety hazard in a crash. The rear camera issue, while less severe, still impacts safety, as the camera provides a wider and clearer view than mirrors alone. I am asking NHTSA to review whether these issues are safety defects and whether they may be connected to known problems or recalls not applied to my vehicle.

* The AEB engaged when it shouldn't have. Yes. * Yes * No. * Yes, Tesla remotely told me that the error codes in my service menu had nothing to do with the AEB engaging when it wasn't supposed to. The problem has been reported to Tesla. * None. On [XXX] a car stopped suddenly in front of me and my AEB engaged when it shouldn't have. My car is a Model 3 Performance and it can stop much faster than most cars. The car behind me came inches from hitting me and my dog and myself were thrown violently forward. This is a *MAJOR* safety hazard and could have caused an accident and has caused accidents in other cases. [XXX] This thread has videos of the incident. There was around 20 feet between my car and the car in front of me when the AEB stopped my car. My foot was already on the brake and I was in the process of stopping at a reasonable rate when the AEB suddenly engaged. I could feel the ABS engaging. This happened another time about a month ago. A white box van two cars in front of me slowed down and turned right and the AEB engaged even though there was no need for it. Tesla has the ability to turn off the AEB but you have to do it each time you drive. Please require Tesla to make the AEB on/off choice sticky so you don't have to turn it off each time you drive. Also please make Tesla fix their software or disable AEB on their cars. Recent accident where AEB caused an accident.

For the last few weeks while driving, my car will automatically put itself into FSD with out me authorization. Mean I will we driving and the car will just put itself into FSD. This has happened about 15-20 times over the last 2-3 weeks. Tesla wants to clean the front camera? Which makes no sense and charge me for it. If the front camera was obstructed, like in the case of fog. The car would alert me that it could not due to being obstructed, which isnt the case.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

Phantom braking (as it's referred to by experts) happened to me twice on the highway using Traffic-Aware-Cruise-Control. Very scary. I was on cruise control going 60 mph when suddenly my car braked suddenly and inappropriately, losing at least 20 mph in a split second before I was able to slam on the accelerator and prevent an accident (rear-end collision). This happened TWICE in the course of 5 minutes on the same highway! There was no obstruction in the road, no cars moving into my lane, nothing but normal road conditions, when it occurred. From my research, this is a huge problem with Tesla vehicles that thousands of individuals are loudly complaining about online and now in court cases in the country. I see there are thousands of reports to your organization about this, but it says you have only complaints from 2021 and later years. However, I have a 2019 and it's happening to me. And it's happening to every single model year out there, just from researching and talking to Tesla owners. This is a major safety hazard, plain and simple. I was inches of being in a rear-end collision, and drivers behind me are extremely upset and vengeful on the road after an incident like this (understandably!). Because of this I fear for my safety and well-being on the road using Tesla's cruise control features. Very disappointing. Above for the ADAS option, I wasn't able to select 2 options, but "automatic emergency braking" is also applicable here as that is what happened. Somehow Teslas are falsely activating emergency braking during cruise control!

When cruise control or self-driving systems are engaged, there have been numerous times when the automatic emergency braking system mistakenly slowed the car suddenly. At 70+ mph, this is incredibly dangerous. The AEBS apparently sees shadows as dangers. Fortunately, there has never been an instance when another vehicle has been close behind.

Two major safety issues need to be reported: 1) The left front lower control arm falling off in the middle of driving, caused car wheel stuck on a traffic street (luckily it was off the freeway 5 minutes ago). The long bolts connected the lower control arms were loss due to the defective design (the bolts are screwed upward vertically, falling off is definitely just a matter of time). I found there was a class action against Tesla due to this problem (it is referred to Model X and S) 2) The other major safety issue I encountered as I turned on the “advanced autopilot “ feature, the car could break suddenly without warning on the freeway. There were no cars or obstacles in the front. I researched online and found many Tesla owners have experienced this so called “phantom breaking” problem as I had (I had experienced this unsafe auto breaking randomly since I have driven this car)

Hello. A recall was issued in 2022 on my vehicle. There was an issue with the wiring harness that would sometimes cause the rear camera feed to be dropped when opening and closing the trunk. According to Tesla, this issue was fixed in 2022 is therefore no longer subject to being fixed again. This issue is occurring again and Tesla is refusing to fix the issue without me paying for it. As this was a recall item, that is reoccurring. I feel that as a safety component that can drop out the rear camera/cross traffic detection system. This is a serious safety concern. NHTSA campaign number: 21VO0DO00. Tesla's own number for this recall is SB-21-17-008.
