2026.20.6.6 update now installing

[MX5]

Previous release I experienced smoother parking and more intelligent lane navigation than before. This release is a step backwards, back to moving into the right lane just before an on ramp when there was no traffic reason causing a merge issue. Parking after this update makes me look like I've never backed a vehicle up in my life. Pretty disappointing, hoping for a correction release soon.

Just installing the update now, hopefully they will have dialed down the phantom sensitivity.

Fingers crossed, the phantom is gone. Last night did update (2026.20.6.6/14.3.5) and no reappearance of any phantoms today!

It seems to be more confident now. CT was about to merge onto the on-ramp and last second decided to take the side road. Little confused but saw a backup on the main road a second later. Looks Ike it just happened and the Cybertruck changed course and I avoided an extra 5 minute or so of wait. I think it was based on vision and not the map. Yeah for me not much complain for several versions so far.

A "bug" for me today after using *Summon* to pick me up. When I got inside to drive home, there was no *Start Driving* icon. I drove away thinking it would eventually pop up on the screen. It never did. At a stop sign I put the truck in park. When it entered park the *Start Driving* icon returned to the screen and I activated FSD. Maybe I'm not operating *Summon* correctly? It had not done this before the update when using *Summon* and then driving away from a stop after using it.

Dumb question but bear with me. I've always parked at home with nice, reliable wifi for Fluffy. I'm in a hotel kind of between homes for 27 more days. Ugh. Questions is: Will Fluffy update over the air or will it wait until I connect to wifi again?

Dumb, right?

Can it not use the hotel's wifi?

Lots of Service mode updates hidden in this release. No software update displays service mode updates or changes in release notes i realized.

Same happened to me tonight. Fsd returned after park. Also had camera blacked out and fsd visualizations error. Truck drove fine. Will see if it happens again ( ive been having summon come pick me up at the door of work, so far pretty flawless… a few jaws on the floor too)

Can it not use the hotel's wifi?

Oddly enough, no. Also can't use the hotel wifi for random things. Security settings on their wifi aren't good enough for some things and the truck may require more security. IDK. I tried this morning before heading to work. Maybe I didn't give it enough time to connect. I got irritated and left without connecting.

Experienced another faux pax today using summon. Parked in same spot at restaurant I had previously used "Summon' with success. A straight shot down the parking lot with a left at the end and about 30 feet to my point of pick-up. 007 was parked with front end directly pointing out from the parking space. Instead of coming out of the parking spot and driving straight down the parking lot, he immediately made a right out of the parking spot and then stopped dead before entering a public street. *I had to make the Walk of Shame back to him in front of my friends. *

On a very interesting note, I held a phone to my ear today in FSD and never received a "Device in Hand Detected" warning for approximately 2-3 minutes of talking. FSD 14.3.5 seems to be very tolerant of having a phone in your hand now.

Well that didn't last long. Installed 2026.20.6.11 today

I believe it is to correct the *Summons* bug. I have a friend who had the same experience using *Summon* with his CyberTruck as I reported having. Went the wrong way and had to stop it.

Updated with post by @pae1andonly summarizing the updates in 2026.20.6.6:

Summarize differences between 2026.14.6.11 and 2026.20.6.6

Key Differences Summary (2026.14.6.11 vs. 2026.20.6.6)
These are both recent Tesla vehicle software branches (likely on the same or very similar FSD Supervised base initially), with 2026.20.6.6 representing a newer major/minor branch rollout that incorporates later FSD improvements and additional vehicle features.
1. FSD (Supervised) Version & Improvements

• 2026.14.6.11: Includes FSD v14.3.4 (with RL upgrades, vision encoder improvements, 20% faster reaction via MLIR compiler rewrite, pothole avoidance in some notes, Actually Smart Summon enhancements, etc.).
• 2026.20.6.6: Includes FSD v14.3.5(incremental upgrade from 14.3.4).
  • Further refinements: Mitigated unnecessary lane biasing/tailgating, better parking decisiveness, improved emergency vehicle/school bus/right-of-way handling, small animal avoidance, complex traffic light/intersection handling, rare object handling, temporary degradation recovery, and unified model across FSD/Actually Smart Summon/Robotaxi.
    • New/expanded stats and feedback tools (e.g., intervention-free streaks, better driver preference memory in some reports).
    • Camera Preview: Now accessible while driving (Controls > Service > Camera Preview) — a notable new usability feature.

2. Core Vehicle Features (2026.20 Branch Additions)

• Dashcam Clip Encryption(new in 2026.20): Clips saved to USB are encrypted for privacy; only your vehicle can decrypt them (toggle in Controls > Safety).
  • Parental Controls (new/enhanced): Block Browser, Theater, and Arcade (Controls > Safety > Parental Controls).
  • "Hey Grok" voice assistant integration (new): Launch via voice, steering wheel, or app; supports navigation, reminders, personality options (early beta, requires connectivity).
  • Security improvements and various bug fixes/UI tweaks carried over or expanded.

3. Other Notes

• 2026.14.6.11was more of a point release focused on stability/FSD tweaks (e.g., driver monitoring sensitivity in user reports) on the 2026.14 base.
  • 2026.20.6.6 is the newer branch (rolled out ~July 2026), bringing the latest FSD to vehicles on/updated to that line, plus the privacy/safety/voice features. It also added Actually Smart Summon for Cybertruck in some contexts.
  • Both share many underlying FSD neural net upgrades, but 2026.20.x includes the fresher FSD supervised version + branch-specific additions.

For your Cybertruck, the 2026.20 branch should bring these FSD refinements, Camera Preview, encryption, and Grok features (check for rollout in your vehicle). Release notes can vary slightly by model/region/hardware (HW4/AI4 common here). Always review in-car notes after updating, and report disengagements/feedback to help Tesla.

Drat! Phantoms back at start of FSD in my driveway and erratically at stop signs under FSD. Updated to 2026.20.6.11/14.3.6.
