2021 TESLA MODEL 3 Complaints

When I use cruise control, the car will brake suddenly sometimes very fast or moderate braking. There is no reason for the car to break. It happens on 2 lane roads and 4 plus lanes. I can not determine if tree shadows cause it. It often breaks when a car is coming from the opposite direction on a curve. It also breaks during the night on a 2 lane road when a car comes from the opposite direction. Sometimes it has freaked so hard that if anything is on the seat, it is thrown toward the floor. I fear I could be hit from behind due to unnecessary braking, so I will only use cruise control if there is little or no traffic on on roads with 4 or more lanes.

Tesla is now making interactive video games and live internet web searching possible on the main front seat display WHILE THE CAR IS DRIVING. The video games are allegedly restricted only to passengers. Web browsing is available to anyone at any time. Why is a manufacturer allowed to create an inherently distracting live video which takes over 2/3 of the screen which the driver relies on for all vehicle information? Tesla has no gauges above the steering wheel. NHTSA needs to prohibit all live video in the front seat and all live interactive web browsing while the car is in motion. Creating a dangerous distraction for the driver is recklessly negligent.

I noticed you have a recall for SOME Teslas about a glitch with the auto braking after latest Beta FSD rollout. My Tesla has had this since day one, and I don't have or use FSD. I do use the adaptive cruise control, and that is when I have problems with my car slamming on the brakes for no reason. I have been lucky, 3 times I have ALMOST, been rear-ended. I have had it in the shop a couple times for the issue, and they tell me to read the manual and the car is fine. I have talked with 5 other Tesla owners, and they have all had the problem of their car slamming on the brakes for no REAL reason. I think the GLITCH is a bigger problem than Tesla is willing to admit, and applies to most Tesla cars. there are even website forums about, "Phantom Braking", which is lingo for the same thing

System erroneously sounded forward collision warnings about once per minute. Automatic Emergency braking faulted and could not be enabled. Firmware version 2021.36.5.2

break backing plate screw loosened and go into the break disk. it create noise when driving and breaking. the loosened screw might the damage the break rotor. the screw was removed from the break disk and tighten again by independent service center The manufacturer have inspected no warning lamps but it create noise. so it is not hard to detect this issue. it first appear on 19 Oct and I have the service center fix it right the way.

My vehicle is a "Tesla Vision Only" (non-radar) Model 3 on firmware 2021.32.21 although this issue occurred on other firmware I've used as well. At night the car will very very frequently brake 3-10 miles an hour for no reason. It's specifically bad at night. It regularly thinks the ongoing traffic is headed in my lane. It regularly slows me down significantly before the top of a hill. Sometimes this can happen 3-5 times in succession within 5 minutes and causes other drivers to react to my vehicle as if it were dangerous. My only recourse is to tap the accelerator as quickly as I can to override the braking or not use the cruise control. This happens mostly on two lane two way traffic roads, often with gentle curves, and worst at night. I now have a car without even "dumb" cruise control. This is not what you think you're buying when you get a brand new $50k vehicle. When I originally received the vehicle in June I had brought up my experience to a technician while they were servicing the vehicle for other purposes they told me that there doesn't appear to be anything wrong with the camera system and that with more firmware updates it would get better. It is not better, I'd say it's gotten worse since I bought the vehicle.

Periodically one headlight starts flashing and my front turn signal won’t work. This typically happens in the middle of driving so I’m at risk of getting home safely.

On September 1st, I was perpendicular back parking on the street in front of my home. Spaces are fairly tight and the street fairly narrow, so it is not uncommon to shift between reverse and drive a couple times to adjust one's fit before parking. That said, a quarter of the way into my parking spot, I shifted from drive to reverse after finishing adjusting. After doing so, I pushed on the accelerator and was sent forward as if I were in drive. I toggled between drive and reverse multiple times over the course of 15 seconds. Pushing on the accelerator continued to send me in the opposite direction, causing me to hit the sidewalk curb in front of me multiple times. The situation resolved itself after 20 or so seconds. Then, the same exact situation occurred on Sept 7 and again on Sept 13, and those times, I nearly hit the car parked adjacent to me. All of this occurred while hold mode was on, meaning the car was not simply swaying with gravity. There could be a host of defects involved in the manifestation of such a problem - perhaps a bug in the software which controls the power train. The swapping of reverse and drive for no apparent reason presents a huge safety concern/liability. I could have hit pedestrians on the sidewalks in front and behind or severely damaged mine and someone else's vehicle. My street is one of two which allow access to a monument. That said, there are always a ton of pedestrians, many of which are young children. I scheduled a Tesla service appointment after the first occurrence. Timestamps and video of each of the incidents was captured and provided to Tesla. They claim there is no issue and that the car was simply rolling due to gravity - despite hold mode. Furthermore, I drive on the same street every day and the aforementioned issue does not happen every time. Even given my three scary experiences, Tesla has refused to take any further inaction, other than to reassure me nothing is wrong with my vehicle.

While parked, as I selected "R" (reverse), the car lurched and displayed two warning messages: "Rear motor disabled - safe to drive" and "Vehicle shutting down - PULL OVER SAFELY". The drive train was locked up and I fear that if the car had been moving when this happened, it would stopped suddenly possibly causing an accident. The car was towed away.

The vehicle will suddenly brake with no discernible obstacles when advanced cruise control is engaged. We experienced multiple “phantom braking” events during an 800+ mile road trip (round trip) last week, which was so frequent and unpredictable that autopilot and autosteer (Tesla’s terms) are unsafe to use. The first half of our trip was on two-lane highways and the car would brake heavily on clear roads and triggered two emergency accident avoidance events when large pickups were approaching in the opposite lane (screen showed a vehicle in red in our lane, audible alarms + heavy braking). The braking was so sudden that we were almost rear ended twice. We chose a different route to return home on a divided interstate, hoping that the TACC system would work. It did not. The car would brake dramatically when we went over a small rise, there was a vehicle in our lane at a significant distance (.5-1.0 mile), or sometimes completely unpredictably. During these events, our speed would drop suddenly more than 20mph. It is an unsafe system to use in even light traffic.
