2020 Tesla Model 3 Complaint Log

During a month-long road trip in the US, I experienced frequent "phantom braking" incidents while using adaptive cruise control. In some cases, Autosteer was also active. By "phantom braking" I refer to sudden hard braking by the car itself in clear daylight conditions on interstate highways with no vehicles visible ahead of me for at least 1/2 mile. By "frequent" I mean that this behavior occurred multiple times per hour over multiple days. I decided to cease using cruise control for the remainder of the trip after the following episode occurred. With cruise control active on a four lane interstate, I was changing lanes to the right to allow a pickup truck to pass me on the left. I had just passed a semitrailer, who was in the right lane. I could see him in my rear-view mirror as I began the lane change. The road was empty and visible for at least a mile ahead on a sunny morning. We were all traveling about 75 mph in a 70 mph zone. While straddling the lanes, the car suddenly slammed on its brakes, requiring both vehicles behind me to take evasive action. I over-rode the car’s action by pressing the accelerator pedal swiftly and firmly. No accident occurred. I stopped using cruise control entirely for several months, and I have only rarely used it since then, and only when the road behind me is empty. In those few recent trials, I have not experienced any phantom braking. Finally, I speculate that the braking may have been triggered by "mirages" of what look like puddles on the road. We humans are familiar with this phenomenon, but the camera AI may have interpreted those as obstacles.

My Tesla Model 3 was involved in a 'fender bender' almost 9 months ago. It took 3 months just to get an appointment at a "Tesla Certified Collision Center" in my town (and I live in a fairly major city - Portland, Oregon). After the vehicle went to the shop it has now been there for OVER 5 MONTHS! This is a result of parts being incorrectly sent from Tesla, parts being unavailable from Tesla, parts being mislabeled and/or 'hidden' in their Ordering system and so many other unbelievable problems that Tesla has had. I have now been without the vehicle for over 5 months and still waiting on some other part that was now ordered over 2 weeks ago. The whole process is completely unacceptable and Tesla has really dropped the ball. I will be selling the vehicle and never owning another Tesla again, the moment it is finally done being repaired. Do I have any recourse? Can I sue Tesla to cover the 5 months of insurance I just spent my money on? Thanks!

Vehicle suddenly braked while traveling 70mph on freeway with traffic aware cruise control engaged. This incident happened 3 times during the same 40 mile trip. No other vehicles were within 50 feet of the vehicle in either direction. A rear end collision could have happened if another vehicle were behind me. No warning sounds occurred or warning indication on the computer screen. I purchased this vehicle used from Tesla 3 days ago. Tesla service has not been notified of issue.

I was on a 3000 mile road trip over multiple interstates (including I-35, I-90, and I-80), and while the adaptive cruise control was engaged, the car would abruptly and aggressively brake when no other cars or obstacles were in the area. This would often be a 30mph deceleration before I could disengage cruise control and take over. This happened repeatedly, in multiple states, and in different weather conditions. At times, it was happening every 10 minutes. The system would sometimes, but not usually, make an alarm noise. This problem has become noticeably worse in later software updates. No accidents occurred because I would not use cruise control if other cars were in the area, and I eventually stopped using it altogether due to how frequently it was braking.

Since recently updating the software I now get a lot of phantom braking when employing adaptive cruise control. This hardly happened in the past. Recently it’s happening every time I engage cruise control Today we drove from San Francisco to Utah on the i80 The car randomly braked 5 times Each time the road was flat, straight with no traffic in front or obstacles or road cones. After engaging cruise control the car would randomly brake aggressively with a few minutes. I would turn off cruise control then try again a few minutes later. The same throng would happen Speeds ranged from 65-75 mph

Since recent software update The adaptive cruise control now randomly applies the brakes while driving on a straight road with no obstacles or vehicles in front. Today driving i80 through navada This happen about 5 times within a few minutes of engaging cruise control. This is a new issue I’d not seen until now. I’d had maybe 2 or 3 incidences of phantom Braking over the last couple of years. Today I had it happen multiple times through the day.

Emergency braking is activated on highway when no obstacle is visible on clear sunny days. This has occurred over the last year but has become more frequent over time.

Car did not react to uncoming car and accident happened. Car was totaled. RECALL NO. 23V-838 involved as the car didn’t have the right safety controls and caused collision

I get "phantom braking" on average about every 2-3 hours of highway driving with cruise control enabled. All of a sudden without any road obstructions or vehicles ahead, the car will suddenly break hard even at highway speeds. Sometimes it happens when I approach an underpass or get to a section where the pavement is darker than before.

I was driving to work on the morning of February 24th 2023 and it was raining. After some time, and while on the freeway, I noticed that my low beam headlamps icon (green telltale) on the center display was not showing. As I always drive with lights in AUTO, and since it was raining (windshield wipers were activated automatically), I expected the headlights to turn on automatically. I worried that I would not be seen well by other drivers, and had to navigate to the controls on the center display and switch the headlights from AUTO to ON manually. The headlights then turned on (I assume, since I couldn't see indications on whether they were on or off on the outside, but the green icon did appear after I pressed the "ON" button). Given that it was raining outside, relatively dark, and the windshield wipers were on, I would expect the headlights to be activated while in the AUTO mode. I have never had issues with this before, and wonder if this came from a software update. The switch to go from auto to manual lights isn't very easy to reach from the driver seat so I would expect the auto mode to work well so this situation doesn't have to happen.

The backup camera on my car (and countless others posted online) sometimes has a 1-2 second delay in starting when in reverse, and often will freeze momentarily while in motion. This problem was introduced when Tesla updated their software some time in 2021, where it was livable but noticeable. Then in a subsequent update, the lag and freezing became extreme and rendered the backup camera useless at times. Then, another software update COMPLETELY FIXED the problem. However, one of the recent updates has reintroduced the issue, albeit not as bad as at its worst, but still a safety risk as unexpected freezing of the rear camera, even momentarily, could cause a potential collision with an object that may appear behind the vehicle. I love the software update model Tesla has. But safety features code needs to be walled off from other functionality so it cannot be impacted by updates.

The ADAS system for the car includes automatic steering, which only works at the speed limit detected or less. The car incorrectly sets the speed limit in many instances as much as 30 mph under the limit. It isn’t safe to drive the car at such a different speed than the rest of traffic. Tesla claims it relies on map data and can read speed limit signs. Most rural roads have no posted limit, so they default to 55 mph. Even in the presence of a posted speed limit, the car defaults to their bad map data within seconds of passing such a sign. Tesla has no mechanism for reporting this bad data to get it corrected. This has been ongoing for more than a year.

This happened on 2/18/2023. After I charged my car at a local supercharging station, I drove on the local roads for about 2 miles when the car started shutting down. I could barely steer, and the computer monitor stated that the brakes were turning off, and other parts, like cameras, were losing functionality. I pulled over into the local park. I was frightened that my car was no longer functional and that I could be in grave danger driving again. I tried to call Tesla but no one answered. I had to go through the app. My dad came and we found a Youtube video that said to walk out of the car to let it restart. Looks like it happened to another owner. We did that and the car started functioning again. Not sure why it did this after a charge. But it happened again 3 mos later when I was on the freeway. Luckily, I knew what to do from prior experience. But I am mindful of this whenever I supercharge my car. I wait after charging to drive. This shouldn't be the case and Tesla should tell people of this issue. I tried to tell Tesla service when I went in for another repair but they ignored my comments.

My car was running in auto-steering mode. Last year it did phanthom breaking 3 times in freeway ( Arizona I-10 from casa Grande to tempe direction). Same happened on 2/14/22, it did phantom breaking for no reason. Speed dropped from 80MPH to 55mph. Luckily no one was ahead or behind me. This is high risk for drivers behind me.

The material used to cover the steering wheel is defective and not up to safety standards. The poor quality plastic used to cover the wheel is a very thin plastic that melts from the sun and peels off causing a safety hazard. I brought this to Tesla's attention and was told they will not fix it without me paying for it. There are number of consumer complaints on the internet for the same issue showing the defective material.

The contact owns a 2020 Tesla Model 3. The contact stated he was not able to operate the rear windows in the vehicle. The contact referenced his concerns about regulation Federal Motor Vehicle Safety Standard: 571-6; not allowing him to open or close the rear windows. The vehicle was not diagnosed or repaired. The manufacturer had been informed of the failure through the App. The failure mileage was approximately 44,300.

Driving on Interstate 295 (it is unclear what the official direction North, south, west). You are going south toward Philadelphia. Some signs say north but in reality it is only for a mile or two then the road bends due south. Every time I travel on this road and just before the Scuddersfall bridge, the car brakes to 30 MPH and it does it again on the other side of the bridge (the same direction). I have reported this many times on Tesla's "bug report" and for the 2 years + nothing has been done to correct the problem. The car doesn't have a problem in the opposite direction. I usually take it off the autopilot at this location to prevent the braking.

On a recent trip, while using the adaptive cruise control on a divided, straight, flat four lane highway, the vehicle would randomly slam on the brakes for absolutly no reason, endangering us and other vehicles behind us, who were not expecting a random slam of the brakes. Driving conditions were ideal - sunny, excellent visibility and very low traffic. There were no oncoming or road-crossing vehicles and no vehicles in front of us on the divided highway to trigger the reaction. This happened 14 times over about 200 miles of driving on our return trip home and over 30 times on the trip out. On the outbound trip, I was using it on both the divided highway and sections where there was only one lane in each direction, so decided to just use the cruise control when there was a divided highway. This is a recent phenomenon, as cruise control has never done that before. The semi-autonomous mode does it all the time as well, so we stopped using it for fear of causing an accident.

The contact owns a 2020 Tesla Model 3. The contact stated that while driving at 35 MPH, she encroached into the right light and was T-boned by a bus. The air bags did not deploy upon impact. The contact did not sustain any injuries and a police report was not filed. The contact managed to drive the vehicle away from the accident despite damage to both the front and rear passenger side doors. The manufacturer had yet to be notified of the failure. The contact stated that the lane assist feature failed to operate as needed. The vehicle had yet to be repaired. The failure mileage was approximately 22,000.

Using Autopilot on an empty highway at appx 65mph, the auto pilot system began to brake aggressively without any obstacles in front of me. As it approached 40 or 30 mph, I pressed on the brake to cancel the autopilot before I was hit from behind. Scary.

This is regarding the computer and the cameras on this car. From the first day that I got this car, I have had the issue that when I use the cameras or the backup camera on this it laggs and this is part of safety issue because I was going to ran over some people when I was reversing. The lagging is very noticibale and I took the car to Tesla multiple times and said is ok but when they send technician to my house, we went for drive and I showed him the cameras and he duplicated the problem. The problem is getting worst and last month the computer was blacked out while I was driving. I need you guys to help me out to either put a recall on this car or return and get my full money back for this junk.

The problem is my car has been in the shop six times for an issue that Tesla claims it is unable to fix. I started smelling a burning smell (smoke coming from my air vents anytime the air is on) and brought it in. The first three times they were unable to find anything the fourth time they noticed debris That was embedded in the heating fins. They replaced that unit. The fifth/sixth time they actually took the HVAC unit out and noticed the entire plastic underneath was melted and warped. Since the smell has continued and I’m worried that it’s dangerous, I had the air quality tested. The formaldehyde levels were 50 times higher than the EPA recommends as a safe level. (HCH0 level of 6 ppm) I’ve submitted all this to Tesla and they said they are currently working with their legal team to figure out if a buy back as possible. The New York Attorney General told me that the car is not viable for a lemon law due to the fact they didn’t do three chances to fix it in 90 days. (The first 2 appointments were in the 90 days but the 3-6th were just past it) The car is not safe to breath air in and my lungs hurt from even spending a few minutes in the car. I’m worried about the effects it has on my health and I feel morally wrong to sell it to anyone else. Please help.

Re: California Highway Patrol Accident Report [XXX] (see doc: [XXX] ). The driver of the Tesla noted that Tesla's FSD Beta version was engaged, and "When (the Tesla) was in the tunnel, (the Tesla) moved from the #2 lane into the #1 lane and started slowing down unaccountably. When (the Tesla) was about 20 miles per hour, he felt a rear impact." In January 2023, I reviewed available Google map data at the approximate GPS location of the accident. (see video: [XXX] ). Multiple conflicting data layers corresponding to that location may have contributed to the accident if the FSD Beta-controlled vehicle referenced the same or similar map data. The ADAS may have read a road closure on the island surface above the tunnel at [XXX] as relating to the lower level of the tunnel, and the lane change and subsequent slowing of the vehicle described by the driver may have been in response to this map data anomaly. In early 2023, I made multiple attempts to recreate the error while driving a Tesla Model 3 with the then-current FSD Beta version engaged. I drove in both directions of the tunnel and observed no abnormal reactions in any lanes of the eastbound tunnel. In one instance on a Sunday at approximately the same time of day and GPS location as the [XXX] accident, while driving in one of the tunnel's upper-level centermost lanes in the westbound direction, an ADAS alarm was triggered, and the system advised that the driver should take over immediately. It did not automatically slow the vehicle or change lanes. I noted that both occurred when GPS Navigation routing information may have been referencing weekend and holiday data versus weekday commute hours data. Previously, I had observed a difference between weekday and weekend navigation routes into San Francisco. A subsequent retest in the westbound direction on a later Sunday at a different time of day did not trigger an alarm.

My car is affected by a product defect where Tesla Model 3's which have blind spot monitoring cameras (all model 3s) during a certain time frame have extreme glare at night, preventing the driver from safely using the blind spot monitoring system. The camera is basically unusable, and this is a feature that drivers rely on to safely view their blind spots. I have done lots of research online, and Tesla repeatedly refuses to fix these product defects under warranty. There are tens of thousands (potentially hundreds of thousands) of affected vehicles, and I'm sure that Tesla is trying to avoid a costly recall, so they refuse to admit that this is a major safety issue and say that it is "within spec". If you search "tesla model 3 side camera glare" in Google, you'll find that there are thousands of complains on forums. Tesla fixes some under warranty, and refuses to fix others. I am aware that there was a recall on Model 3 vehicles already due to the rear view camera going out, which the NHTSA deemed a safety issue. I would argue that the defective blind spot cameras are a FAR more significant safety issue, because the rear-view camera is used almost exclusively during slow speed maneuvering into tight spaces, while the blind spot cameras are used on freeways for high-speed (60-70mph) lane changes. I have reached out to Tesla and requested that they fix this under warranty as it is a major safety issue, and they told me that newer production models have had the problem fixed, but that my model year needs to pay to have it fixed by Tesla. I have attached pictures of my conversation with Tesla to this complaint. Please take action against this company, which is putting its customers at risk because they don't want to bear the financial cost of fixing their product design defect.

I don't think TESLA has dealt with recall 22v-702. TESLA has not notified me of the status of the recall. Please let me know if they have solved the problem.

This is the first and only time this has occurred as of today, 1/1/23. Around 11:45am EST, I was driving down a side street with no traffic coming towards me, behind me, or in front of me (and with no objects in the road). Suddenly, my brakes were aggressively applied and a warning came up on my screen saying it was the Automatic Emergency Braking that had been applied. It then released a few seconds after. I do not have the Autopilot option on my car, and I did not have any type of cruise control engaged at the time. If this had occurred in traffic for no reason it easily could have caused an accident.

I was on the exit lane coming from Costco on 12/31/2022 at around 12:20 PM with a speed of about 40 miles . My exit is about 100 yards away. Tesla model 3 that I’m driving suddenly accelerated at high speed and pulled towards right and hit the wall next to freeway exit lane. Then it hit the wall on rear tailgate and rolled to middle of freeway within a fraction of seconds. Two vehicles coming on the freeway hit my car and after second hit my car completely stopped in the middle of freeway. I was able to come out safely and later CHP officers came and towed the vehicle

Recall 21v-00d was registered DEC 2021, notice said waiting for parts. It's been OVER 12 months and no parts yet? Also, the phone number Tesla has listed on the recall notice and their recall info on your website goes to a self-service site that states to use your Tesla app to schedule a repair so there is no way of contacting the company directly to find out about the status of the recall.

The Rear Drive Unit of our Tesla failed on our Tesla Model 3 2020 (2 years at the time of incident). It is no longer available for inspection as it was replaced by Tesla. We had our drive unit fail for our 2020 M3 driving in the middle of what is considered one of the most dangerous freeways in [XXX] . After all the warnings came online, we had 30 seconds before the entire car stopped. Of the warnings (Power Reduced, Acceleration and Top Speed Reduced, Automatic Emergency Breaking is Disabled) there was no indication that the car would shut down. We made it to the exit ramp, but couldn’t make it to the shoulder so we blocked the entire exit. [XXX] was able to come in and help tow our car to a safer location. We took it to Tesla to be serviced and when asking the service rep if there’s any way we could have seen this coming, she just brushed it off as “it happens” and that there was no way to tell. It took us a while to feel comfortable with that. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Phantom braking: While in cruise or autopilot mode, it suddenly brakes on freeway without any obstacles observed.

While using the autopilot function car unexpectedly brakes almost to a stop for no apparent reason. This happened in different driving conditions, day, night, other cars around and on empty roadways, both divided and connected two and four lane freeway and side highways. Brakes so hard that objects fly off the seat and cars traveling behind my vehicle have had to break themselves and or change lanes.

There have been recent reports of Tesla FSD accidents that are now under investigation by NHTSA relating to crashes that occurred under difficult visibility conditions. A video I recorded several years ago while driving into a fog bank in NW Washington, about an hour North of Seattle, is linked below. Seeing the fog bank ahead and with no traffic in front or close behind me, I let the car proceed into the fog until the system triggered a takeover alarm. Usually, at this point several years ago, when the driver wanted to disengage FSD, the driver did so by raising the gear selection stalk. Raising the gear stalk disengaged TACC ONLY in this incident, and Autosteering remained active. (see: [XXX] ) After disengaging TACC, the car was slowed by regenerative braking but still under Autosteering control. Turning the steering wheel finally disengaged Autosteering, but that occurred second and was delayed by the driver's confusion over why raising the gear stalk wasn't enough to stop the alarm. Applying the brakes would have disengaged FSD completely - but that wasn't wise with low visibility. I tried re-engaging FSD briefly while still in fog (not shown in this video), and the system refused. This brings to mind a previous documentation video where, with FSD engaged, turning the wheel disengaged *Autosteering, but *TACC remained active. Again, the driver was not initially cognizant that TACC was still active (see: [XXX] ). I believe a subsequent recall remedied this 2nd example, but perhaps the fog bank-type takeover alarm was not affected by that recall remedy. Finally, I have one more video documenting the ability of FSD to see under challenging conditions, in this case, light rain, heavy rain, and eventually hail. No alarms were triggered (see: [XXX] ). Note: I no longer own the vehicle associated with this VIN. See the firmware version shown in the video for approximate dates of these occurrences.

Was driving Tela on 237 Clavaras Blvd heading towads 880 South just before Abott ave in Mlipitas town California Tesla Model 3 acelrated suddenly hitting the car in fronts, emegency automatic braking did not kick n. Earlier it had autopilot set not sure if it tured off. We were surirsed, my wife was driving and I was i passenger seat none of the safety measure worked in the Tesla. My car is totaled.

Phantom braking issue. Cruise control set at 68mph. Medium freeway traffic at 7pm. Noticed disabled car ahead on the shoulder. No danger. As we approached the car, my car went into a panic stop as if it thought a collision was ahead. Car braked and skidded. I was able to regain control and accelerate and avoid a rear end collision. No waring or repair issues

The contact owns a 2020 Tesla Model 3. The contact received notification of NHTSA Campaign Number: 21V00D000 (Electrical System, Visibility, Back Over Prevention) however, the part to do the recall repair was not yet available. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and informed the contact that a request was not needed at this time and that he would receive a notification for an appointment for the recall repair. The contact had not experienced a failure. Parts distribution disconnect.

When using autopilot cruise control, the car will brake hard for no apparent reason. I only use cruise control on limited access highways. When this happens, I immediately disengage cruise control and drive manually. This can happen at any time. I have driven the car cross country several times, driving all day. Some days it won’t happen at all, and on some days it can happen several times. I’m concerned that if someone is close behind me, they could hit me from behind. This has been happening for the past two years

The driver seat occupancy weight sensor has to be replaced twice now. The car does not recognize someone is in the driver seat. It is unclear whether the airbags would deploy if I was in an accident as the car is unsure if someone is even inside. When I get out of the car it stays on. When I put it into reverse without having the seatbelt on it slams on brakes.

The contact owns a 2020 Tesla Model 3. The contact stated that while utilizing the ADAS features including the Adaptive Cruise Control, the vehicle independently applied the brakes while driving at highway speeds. No warning lights were illuminated. The vehicle was not diagnosed. The vehicle was not repaired. The dealer nor the manufacturer was notified of the failure. The failure mileage was approximately 25,000.

The 2020 Model 3 uses a fiberboard front skid plate, that is intended to protect coolant lines that protect the battery. When wet, the fiberboard front skid plate degrades and exposes the coolant lines to damage from road debris, which could lead to a battery fire. Attached are photos of this damage. Tesla should be required to use a sturdier material to protect against this risk, and replace existing fiberboard front skid plates with the sturdier material.

phantom braking/slowing. Also, please do what you can to stop deployment of FSD by the end of 2022. Not only is the car and drivers not ready for it, the infrastructure is not as well. In addition, the 100% reliance of cameras for auto aware CC and FSD is absolutely flawed. Tesla must add radar—better yet, LiDAR—to their vehicles irrespective of FSD but, absolutely for FSD if they insist on pushing it before drivers, infrastructure, and the vehicles are ready for it. My opinion, FSD should never be allowed on any vehicles—maybe by the 22nd century…

Phantom braking when using cruise control. Happens practically daily, but most recently this morning at 9:25am.

The turn signal is attached to the left and right side blindspot camera. When using the blind spot camera at night, the turn signal light “bleeds” into the camera blocking your view. So it becomes a safety issue when switching lanes at night, especially on a dark freeway. I have contacted Tesla and stated that “the camera performance on older vehicles is neither a defect of materials nor workmanship… which is has been enhanced in newer vehicle production. “

The car broke down completely saying that "Electrical system failure". It is immobile. This is dangerous as I was driving on the freeway and it suddenly started showing lot of warnings. Warning included "12v power system failure", "Electrical system failure". "Brakes might not work". Somehow I got in to the garage and the car is now immobile. It does not even lock. It is in the same condition as I parked. Cannot open other doors. This could have been life threatening if it had stopped on the freeway. With the price and safety rating, I never expected Tesla to have total failure.

This cocksucker blasts oncoming traffic with DISCO HIGHBEAMS every single fucking time there's a lonely oncoming car on the highway. Someone's gonna shoot my ass for blasting them repeatedly with highbeams. Because autosteer is connected to auto highbeams, I can't turn it off unless I turn autosteer off and drive like a 1995 peasant.

Ever since a recent software update was downloaded and installed, my Model 3's incidence of "phantom braking" events while using traffic aware cruise control/autopilot has gone up by a very noticeable degree. It has always been a known issue, however since the redundant safety systems (radar and ultrasonic sensors) on my model year vehicle were disabled by one of the recent updates, phantom breaking events that can possibly CAUSE a collision event or loss of control of the vehicle happens far more frequently. Instead of occurring once every 1000 or so miles, it now occurs two or three times every 250 or so miles, judging from performance on recent cross-state road trips. My car does not use the "Full Self Driving" package that Tesla offers.

On October 29, 2022 the Michelin tire on my 2020 Tesla Model 3 that had 16,000 miles on it, suffered catastrophic tread loss while traveling at 70 miles per hour on California Route 110. The tire was the original equipment tire supplied with this vehicle when my lease began in January, 2021. The DOT number on the tire was B9 EL 04 EX 0419 and the tire size was 235/45R18 98W. The tread did not wear out, the tread delaminated from the tire and was lost on the side of California Route 110.

Traveling on a clear, dry highway on a sunny morning and once again the next day we experienced phantom braking. This occurred three times in two days. In all cases we were traveling at 75mph and were using the adaptive cruise control. In all cases there were reflections in the road from the heat mirage or from something far down the road. The car acted as if it saw something in the road and braked sharply. The driver had to accelerate to override the braking.

While in cruise control the car baraked excessively on a straight 4 lane divided highway even though there was no other vehicles in front, to the side or coming on the opposite direction. This happened on 101 north of Paso Robles

The 12 volt battery on my T2020 Tesla Model 3 failed without warning last week when I entered the driver's side and closed the door. There was a very brief warning on the control screen that the "12 volt battery should be replaced soon." Then the screen went blank and all controls to the car were rendered inoperable. I could not open the door. I had to go on line on my mobile phone to the Tesla website to get the manual to remind myself how to use the mechanical latch on the door. I then exited the car, and could not re-enter the car. My biggest concern is that if a child or an animal were in the back seat there would be NO WAY to get them out without breaking a window. The Tesla technician came the next day to change the 12 volt battery. To do this on a Tesla Model 3, he first had to use an external 12 volt battery to open the "frunk", which he did. However, the car's 12 volt battery was so dead that he could not jump it. He then had to "break in to the car" by inserting a pneumatic pillow into the driver's side window so that he could insert a coat hangar he made himself (he told me Tesla does not supply them!). It took him about an hour of fumbling before he was able to open the mechanical latch on the driver's door; this allowed him to disconnect the main battery unit below the rear seat so he would not be electrocuted when he changed the 12 volt battery in the frunk. So even if I had had a set of jumper cables and an eternal battery at the time the car's 12 volt battery failed, I would have had to break a window to get into the car to rescue a child or animal who might have been trapped in the car. This is clearly a design flaw that should be corrected to improve the safety of a car that I otherwise like very much. I should mention that the Tesla technician said he was seeing a lot of these 12 volt battery failures; he had 4 more to address that very day. Thank you.

Phantom braking has occurred numerous times on cruise control. No cars or other objects nearby. Set up appointment with Dealer but the service dept said they are aware of the issue and at this time nothing can be done.
