Parts of 2019.8.3 are great, but ...

[ePowerman]

... the car will not complete an auto lane change anymore! Not in standard autopilot or on NoA. I tried it multiple times on my 20 mile commute to work this morning and it was back to hesitating and starting the lane change but then suddenly veering back to the lane. The strange thing is that this EXACT same issue happened with the last update. It eventually resolved itself and became perfectly confident and aggressive with the lane changes.

So why is this occurring? Is it some type of calibration that it needs to do for X amount of miles before being able to complete a lane change? The cameras aren’t dirty or anything. I even did a hard reset (brake + both buttons), but that didn’t help.

The rest of the updates, including the additional power, are great. The car is able to do a greater than 90 degree right turn and merge onto another highway! I’ve tried that same turn before and it always failed (it’s a fairly sharp turn). So definitely a big improvement there.

As someone else mentioned in a post, the shaking/shimmering cars in the display are more steady. The car also feels more solid in the lane and doesn’t drift much (wasn’t doing much of that before anyway) and doesn’t hug the outside or inside of the lane while in a curve. So overall, if I can get it to automatically change lanes, the update would be amazing!

I had the same issue this morning, 1/2 way through a lane change then swerved back, causing the driver behind me (going for a pass) to hit the brake probably thinking WTH!

Lane change is working pretty well on 5.15. It's much better than 50.6 and seems like 8.3 broke it again?

Dirty sensors to cause false car traffic identification?

Have you experienced any phantom braking episodes during your drive? I think I’ve pinned it down to someone driving close to the lane line ahead of me. Had 3 incidents where AP decided to brake check me on the way into work today with no clear need. First time I’ve given up on AP for my commute... so disappointing since other aspects of AP improved.

I had a phantom break this evening on my way home.
Large bus to my right, SUV on my left but a bit ahead of me. Seemed like the SUV was drifting toward the line or very close to it, but from what saw never crossed or put me in danger.

 

[ePowerman]

Yes, phantom braking even on this release. But seems less than before. Braked for an overpass.

Just got the update today.

I haven't noticed any auto lane change weirdness. Jitter of the neighboring cars in the AP display area is def smoother now.

Acceleration from a dead stop is SOOOO much better now. Feels more like my S85.

Also there's more regen at higher speeds than before. Someone else made this observation as well in another thread.

Auto lane changes are working fine for me too. That was one of the first things I tested after getting the 8.3 update.

Strange. I’ve had zero issues with lane changing on 2019.8.3. Was even using it today in heavy rain. Though I did experience aborted and hesitant lane changes in 2019.5.15.

Still on 2019.5.15
I experienced the aborted lane change scenario yesterday for the first time, but it was pouring rain. So no issue in my mind for that behavior given the awful visibility.

Same, installed it yesterday morning. Commute went fine changing lanes several times automatically. It only aborted when a car came racing up when it saw the blinker. Rock solid and reliable.

It’s not changing lanes for me either. Hopefully this clears up after some more driving. (Calibrating?)

I lost any sound from rear speakers. Went to local Tesla Service Center - tech said its known bug, expect correction in later Version update.

 

[MacGreiner]

I'm still on 5.15 and the swerve back on lane change happens nearly every time I engage it. Judging by the look on folks that pass me after it aborts mid way, I am adding to the shorts pool.

I too cannot get lane change to work. I have 8.3. While it worked in trial, but it has not worked since I bought it.

 

[Knightshade]

FYI I got an update notice overnight (presumably 8.3) but when I went to the app in the morning the update was gone

Looking on reddit others had this happen overnight too and at least one guy was told by Tesla 8.3 had been pulled back

Recieved Update Push Notification without update. : teslamotors

Do you have AP or EAP? Only EAP will do the auto-lane change. AP just keeps you in your lane. Sorry if you knew this, just throwing it out there since there are now 2 types and they seem to love to demo EAP.

You may be right as I have AP. But in the manual and the Tesla help videos that distinction is NO made. If you can point me to a Tesla page I will quiet down.

The video says enhanced autopilot right at the start.

The owners manual does too. See page 65 where it mentions the features as described only apply to those with enhanced autopilot or FSD.
