2025 Tacoma trail hunter
When I drove on the paved road, my 2025 Tacoma Trailhunter malfunctioned and displayed on the dashboard,
See photo attached. I called a local dealer, made an appointment a couple of days later, and cannot walk in right away.
Please help me understand what caused it, etc. Thanks a lot.

"Toyota Tacoma (i-FORCE MAX) indicates a fault in the high-voltage battery, inverter, or powertrain electrical network. It requires professional code scanning at a dealership because the truck may limit power or refuse to start."

In other words, it's basically impossible for us to troubleshoot your issue with the information you've provided.

Side note/tip: Remove your actual address from your location on your profile please. Too many weirdos out there.

Conti.
Sent my Tacoma to the Toyota Dealer; the dealer could not find any issues, then he reset the Tacoma bank-1 (I don't know what it is). I picked up my Tacoma back home and only drove around 30 miles; all warning lights turned on while I was driving. It is so bad. Then called the dealer again and sent the Tacoma back. The dealer found the issue and fixed it needing cost more than $2700, and let me pick it up next week. See photos below.
