2021 TESLA MODEL 3 Complaints

Heating failed in -10 temperature for approx 40 miles. Window became ice covered and would not clear. Interior of car was 33 degrees and heat came back on when plugged into charger.

The rear seat doesn’t detect kids under 50lbs. Putting the seat in car seat mode only disables the seatbelt alert and doesn’t keep the rear fans on. You can turn them on manually, but the car forgets that they should stay on if you precondition the cabin from the mobile app. Meaning that my child cooks in the back seat due to lack of rear cabin conditioning unless I remember to turn it back on in a buried menu every time.

Ever since Tesla pushed a software update to my vehicle on or around 12/20/23, the vehicle screen crashes and reboots every time I enter enter my vehicle. The software version is 2023.44.30.5.1. The vehicles systems; backup cameras, parking sensors, etc. are in operable for approximately 2 minutes during the reboot process rendering the vehicle unsafe to operate. I have reported this issue to Tesla on multiple occasions with no resolution offered other than a note that this is “considered” normal with the current software version. I was pushed software update 2023.44.30.8 on 1/8/24 and the issue persists. I have scheduled a service center appointment for 1/29/24.

FSD Computer module (AP3 module) when starting to fail causes all active safety systems to top functioning, including but not limited to Lane Assistance, Automatic Emergency Breaking, Adaptive Cruise Control, Lane Departure Warning, Lane Keeping Assistance, Blind Spot Warning, Pre-collision systems, etc. This is due to the ECU that processes the video feeds from the cameras needed for these function begins to fail, and is not surprising. What is surprising is there are absolutely zero customer or service facing alerts for this issue. Customers simply are unable to manually activate some features, vehicle display has difficulty recognizing objects and lane markings, and the service menu (meant for vehicle service/repair) shows part of the ECU as critical in diagnostics, but does not provide an alert. I can only guess that as previously only half of the module was used at a time, with the second half being for redundancy incase of a failure on one part of the unit, still allowing for full functionality. However, in newer versions of the vehicles software both halfs of the module are used simultaneously to increase processing power, thus eliminating redundancy. It is possible that due to the past redundancy that a failure of one half of the unit was not considered a cause for alarm (though I would have hoped a failing component would have caused an alert, unless the companies hope was that one half would work long enough on its own until it no longer needed to be covered under warranty). However, given both processors and now being actively used there should definitely be alerts and warnings. In addition to losing the convenience of several of these systems there is also a negative safety aspect of systems such as accident avoidance, pre-collision seatbelt tensioning, and others may not work in a pending collision (not that I have seen these systems function properly in past collisions when the module was fully working).

When autopilot is engaged, car unexpectedly brakes with no obstacle in front of car. Some called it “phantom braking”.

The latest software update version: 2023.44.30.5.1 08a3a7856854 Is too stringent with having to keep eyes on the road that looking in the mirror causes it to beep. Also having to touch the steering wheel constantly is dangerous because if you move with slightly too much force, it disengages autopilot. I only use the autopilot feature on the freeway and I have never had an issue until this update, which I believe was made to make the system safer. In my view it is now much less safe since I’m not able to check my mirrors and ultimately I think it makes the autopilot feature useless. (I will not be using it) this is also less safe, in my view. Because before I would watch the road as the car steered, ready to take over, so it was like having redundant safety (human + machine). Now I’m back to just human safety.

Autopilot feature is now unstable as I get constant nags if I look away for a few seconds to check my surroundings or check my navigation.i have been locked out of the feature multiple times over the past week forcing me to make navigation changes while manually driving.

Driver assisst function for cruise control/autosteer failed/malfunctioned. Applied Emergency braking systems while autosteer/driver control active. Multiple times on freeway. OTA software Updates require additional data downloading and are not required to install. Never received update and safety issues resolved via OTA are already being exposed and they are not allowed to do anything to prevent any damage or loss to the vehicle. Wifi at all government EV charging stations is a basic requirement.

After the latest update the Tesla autopilot feature is very unsafe to use. The screen constantly pings and nags the driver to pay attention drawing my attention away from the road. The system has become so sensitive that adjusting the AC down a degree causes the warning to pop up which distracts the driver and in my opinion is significantly less safe than the older version. The warnings are too sensitive and the noise/warnings flashing are significantly more distracting

concerns about the latest software update for the Tesla Model 3’s autopilot system, which, in my view, significantly compromises safety. As a Model 3 owner for over two years, I have generally found the vehicle and its features to be reliable and safe. However, the recent update has introduced an overly stringent hands-on-wheel detection mechanism that is not only inconvenient but also potentially hazardous. The new update requires frequent and often forceful interaction with the steering wheel to assure the system of driver presence. This change is drastically different from my previous experience, where I received only one hands-on-wheel violation in two years. The current sensitivity of the system disrupts the smooth operation of the autopilot, leading to frequent and abrupt disengagements. I have found myself struggling to maintain the system’s activation, inadvertently causing the vehicle to exit autopilot mode multiple times. This issue goes beyond mere inconvenience; it actively detracts from driving safety. The need for constant and sometimes aggressive adjustments to satisfy the system’s requirements is distracting and can lead to erratic vehicle behavior. The irony is stark: a system designed to enhance driving safety and ease is now a source of potential danger and stress. The unpredictability and over-sensitivity of the updated system could lead to dangerous situations, especially on highways or in heavy traffic, where sudden disengagement of the autopilot can be particularly risky. As a driver, I now find myself more focused on keeping the autopilot engaged than on the actual driving conditions and surroundings, which is surely contrary to the feature’s intended purpose. I urge the NHTSA to investigate this issue as a matter of urgency. The balance between ensuring driver engagement and maintaining the operational safety and rel
