Current Events > Tesla Model Y plagued by phantom braking incidents

(+) Yeah! (+)

Our Model Y, delivered in August of 2021, was produced quite soon after Tesla took the curious decision to remove radar sensors from the Models 3 and Y. Ostensibly this was because the optical sensor-based Tesla Vision system was so good the radar sensors are unnecessary. I'm inclined to disagree.

I can't conclusively say that it's because of the missing radar, but I can say that our Model Y is bad at detecting obstructions ahead. Really, really bad. The big issue is false positives, a problem that has become known as "phantom braking" among Tesla owners. Basically, the car often gets confused and thinks there's an obstacle ahead and engages the automatic emergency braking system. You get an instant, unwanted and often strong application of the brakes. This is not a problem unique to Teslas. I've experience it on other cars, but very, very rarely. On our Model Y this happens constantly, at least once an hour and sometimes much more often than that. In a single hour of driving I caught five phantom braking incidents on camera, two hard enough to sound the automatic emergency braking charm.

This is a massive problem. It happens on both the highway or secondary roads, any time the cruise control is engaged even without Autosteer. It means the car's cruise control is patently unsafe, which means the entirety of Autopilot is unsafe. And that, of course, means the car itself is unsafe.

When the system isn't panic-stopping for ghosts, Autopilot works reasonably well. On the highway it's nigh-perfect, keeping to lanes and even changing with barely any driver intervention with Navigate on Autopilot engaged. It really is an asset and a potential safety boon -- so long as you the driver pay attention. However, on secondary roads, Autosteer easily gets confused by lane markings, especially in the case of a second lane opening up to the side. The car is constantly wanting to swerve to the right to take up both lanes, then jump back to the left again. I wish Tesla would take a cue from Cadillac and simply disable this function on roads where it doesn't work well.

This seems very not good

At this point Tesla shitty build quality has got to be concerning when they were first starting sure fine but now its still shitty the trim still has gaps and other problems Us needs to investigate tesla

Look man they're just a small indie car dev who can't afford to compete with the big names

This is embarassing, it's like tesla's engineers are cutrate or something... oh wait, they are and always have been.
