3. Ask for a bulletin and software check

4. Check warranty terms before DIY
   Modifications such as lifts, tunes or aftermarket electronics can complicate warranty coverage. Look at your warranty booklet or ask the dealer before changing anything related to the symptom.

Applies to: 6th generation 4Runner, 2025 and newer, with the 2.4L turbocharged i-FORCE and the i-FORCE MAX hybrid, both with the 8-speed automatic. This is a new platform with little long-term history, so most entries are general symptoms; when the truck is under warranty, the dealer is the right first stop.
