Update Overview
Per The Tesla Newswire, Tesla Summer Update 2026.26 begins rolling out to the first 1% of the fleet. Target: Model 3/Y, with batch expansion to follow.
3 Traction Control Modes
1. **Auto**: Normal driving conditions. Default safety mode that resets at the start of each drive.
2. **Slippery Surface**: For bad weather like ice or wet roads. Slip detection + torque distribution optimization.
3. **Stuck Assist**: For getting unstuck in snow, mud, or sand. Allows slip when needed to regain traction.
Access: Controls → Dynamics → Traction Control Mode.
Why This Update Matters
(1) Reinforces where Model 3/Y (sedan/SUV) lacked in winter/off-road scenarios, (2) brings Cybertruck-like off-road-mode UX to sedan lineup, (3) exemplifies Tesla's software-only hardware-utility expansion.
Rollout Flow
Starts at 1% and expands sequentially. Release-note changes and safety-data reflection are key validation axes for batch expansion.
Watch Next
(1) Next batch-expansion timing, (2) country regulatory approvals, (3) inclusion on Cybertruck / Model X/S, (4) Traction Control mode usage data → potential off-road feature expansion.
