My advice is report the incident to the NHTSA. We sold our Tesla M3 because TACC was dangerous after owning it for 17 months. Initially phantom braking was a regular occurrence then it improved a bit but with “ vision only” it got much worse. Our diesel Civic has ACC and does none of the scary...

You mean like Microsoft, their software crashes all the time too.

We sold our model 3 because of phantom braking and bought a Honda Civic which has ACC, blindspot detection and lane assist. The Honda works perfectly all of the time. No scaring my wife witless it just works. I have no doubt other manufacturers also have working ACC too but sadly Tesla’s TACC is...

I guess it is more about engineering and sales. Honda is an engineering company and Tesla appears to be sales orientated. Unfortunately the hype surrounding self driving turns out to be just that.

Yes I could but imagine driving a Honda that just works anywhere when using adaptive cruise control.

We sold our M3 SR+ in November because of phantom braking. We bought a Honda Civic and it has ACC which works perfectly.

TACC is dangerous ACC in the Honda works

We got rid of our model 3SR+ because TACC was too unreliable to use. We had too many phantom braking incidents which only got worse when vision only came in. It is a shame as we really liked the car. The replacement car, a diesel Honda Civic has ACC that works perfectly on minor roads, in town...

We went on a 1200 mile journey recently in our June 2021 M3 SR+ mostly on dual carriageways in Scotland and motorways in England. I have to say the car was much better on the motorways, it had a few hesitations but nothing serious. On dual carriageways it still gets confused by vehicles at...

We live in Scotland. We traded in our Jaguar XJ for a Model 3 in June. Since then we have driven 4500 miles. We have done 3 trips of over 1000 miles. Things we like: The Tesla charging network in the U.K. is excellent although some stations on the busier motorways are becoming full and you may...

We have a 2021 M3 with 4200 miles. Stopped using TACC as it is too tedious due to dangerous braking. Reported the issue to the DVSA in the UK and they are monitoring the situation and talking to the NHTSA. Suggest you report the issue to your regulatory body which is the NHTSA in the USA. Tesla...

That would be good but it would be a hell of a climb down for Tesla. I vote for standard cruise now please.

If you have safety concerns about TACC or AP report your concerns to the regulator in your country, that is the DVSA in the UK https://forms.dvsa.gov.uk/Vsdr/create the form is very easy to use and quick to fill in. I have asked the DVSA to investigate hard braking by TACC after a near serious...

TACC is not fit for purpose currently. We have a 2021 M3 with about 3000 miles on the clock. On minor roads the cruise control will experience many "phantom braking" events. Even on the UK's best motorways large vehicles changing lanes will cause the Tesla to brake for no reason. My advice is...

I have received a response from the DVSA and they require evidence that TACC can be dangerous. I responded quoting the Norwegian example where a M3 was rear ended by a van and then that was hit by a lorry...

I have had severe PB while using TACC and the lorry behind was almost sideways trying to stop so I don’t think the software takes into account what is behind. There is a well publicised vehicle accident in Norway where a M3 brakes for no valid reason and is hit by the following van which was in...

I have a 2021 car and agree with SalisburySam the braking is very aggressive and scares the hell out of my wife. Scaring my wife is not a good thing and will be the demise of this Tesla.

Yes of course I reported it to service, and yes of course he went through the logs. The technician then reeled off all the things that make TACC freak out including, shadows, pillars, large vehicles pulling over, worse in rain, basically all the situations we find ourselves. What he couldn’t do...

Haroldo, I am old, my reactions are slow which is why I lose when playing against my grandkids at anything that requires a quick reaction. I have had my M3 as long as you and have had about half a dozen very dangerous “phantom braking” occurrences. I have learned to dab the accelerator to...

We had a severe case of phantom braking at the weekend. Tesla have responded and basically can’t do anything at present. There is “allegedly” better firmware in the US but the U.K. software is behind (2021.12.27.7). I have officially reported the incident to the DVSA in the U.K. see Vehicle...

Hi I also have had multiple phantom braking events and at the weekend on a 500 mile drive it happened 4 times. Twice on the crowded M6 in rain at 70mph. There was no valid reason for the braking and it could have resulted in a very serious accident. I have reported this to Tesla and due to their...
