FSD 14.3.7 Review: Tesla Fixes the Regression That Made 14.3.6 Miserable
Tesla pushed Full Self-Driving version 14.3.7 on August 2, 2026, and the short version is: it fixes what 14.3.6 broke. If you've been white-knuckling through the past week while the car braked for phantoms and jerked the wheel at intersections, this update is the one you were waiting for.
14.3.6 Earned Its Reputation
I don't love calling out Tesla regressions publicly because every stumble gets amplified while genuine improvements get buried. But 14.3.6 earned it. The brake-stabbing was real. The wheel-jerking at low speeds was real. And the manual turn signal override, which I use constantly to override the car's lane decisions, was effectively broken. The car just ignored it. That's not a quirk when you're trying to stay out of trouble on a busy stretch of highway.
14.3.7 addresses all three of those specific problems. Brake-stabbing and wheel-jerking are gone. Turn signal override is responsive again. And the one thing 14.3.6 actually got right, improved parking lot behavior, carried over into this version.
The Avoidance Maneuver
The detail worth paying attention to: 14.3.7 successfully performed an avoidance maneuver when a vehicle changed lanes without warning. That's exactly the kind of situation where a bad intervention doesn't just fail to help, it makes things actively worse. So when the system handles it correctly, it matters.
Worth keeping in context, though: FSD is still designated Supervised, meaning driver oversight is required. The avoidance maneuver is a good data point. It doesn't change the designation.
What It Still Can't Do
Potholes. Uneven pavement. Sharp transitions where road surfaces meet at different heights. The vision-based approach just doesn't process 3D road surface changes well. This isn't new in 14.3.7. It's a consistent limitation of the camera-only system. When the surface changes abruptly, the car doesn't adjust its handling the way you would instinctively. You get the full bump instead of a slight lift off the accelerator. Not dangerous exactly, but noticeable every time.
Also still present: inconsistent auto wipers. In light or variable rain, the behavior is erratic. Not unusable, but not something you can just set and forget. And the Online Routing feature still occasionally produces routes that don't make sense. (I've watched it add significant time to familiar trips for no apparent reason. One possibility is that it's routing around traffic data that's wrong or stale, but the result from the driver's seat is just illogical.)
A Note on Speed Profiles
FSD includes Speed Profiles, one of which is a Sloth mode that runs the car below normal speeds. It's useful in neighborhoods and parking situations where you want the system to behave conservatively. It doesn't fix the pothole problem, but it reduces the impact when you hit one while FSD is active.
Bottom Line
14.3.7 is a recovery update. It earns back what 14.3.6 gave up. That's not high praise, but it's accurate. The braking and wheel behavior from last week's version were the kind of thing that makes you question whether to leave FSD on at all. Those are fixed. The parking lot improvements held. And the avoidance maneuver is worth watching as more people report in.
But the road surface problem isn't solved, the routing still has quirks, and the wipers still can't make a decision in light rain. Meaningfully better than 14.3.6. Still a work in progress.
