Toyota's newest recall for the 2026 Grand Highlander covers a front steering knuckle that can crack and break, on 617 vehicles Toyota estimates are potentially affected across the 2026 Grand Highlander and two Lexus nameplates. It's campaign 26V598000, filed with NHTSA September 17, 2026, the newest campaign on file for any of the three.
What cracks, and what does Toyota replace?
Campaign 26V598000 covers certain 2026 Toyota Grand Highlander and Grand Highlander Hybrid vehicles, plus five Lexus variants: TX350, TX500 Hybrid, RX350, RX350 Hybrid and RX500 Hybrid. Toyota told NHTSA the defect is a manufacturing error: the front steering knuckle may crack and break, which can cause a loss of steering control and increase the risk of a crash.
The remedy is a free inspection, with dealers replacing the front steering knuckles where necessary. Toyota expects to mail owner notification letters November 2, 2026. NHTSA's record puts Toyota's estimate at 617 vehicles potentially affected across every Grand Highlander and Lexus variant this campaign names.

How does the Grand Highlander's complaint record break down by year?
Owners had filed 230 NHTSA complaints on the 2024 Grand Highlander, 71 on the 2025 and 33 on the 2026, as of September 23, 2026. Every model year is on the Grand Highlander hub.
Only the 2026 model year is named in 26V598000. None of its 33 complaints so far name steering; the categories owners used most are Other (11) and Body, Seats & Latches (8).
What is the Grand Highlander's own recall timeline?
The 2026 Grand Highlander carries three NHTSA campaigns on file, the new one included.
| Campaign | Filed | Component |
|---|---|---|
| 25V744000 | Oct 30, 2025 | Back-over prevention, display function |
| 26V437000 | Jul 8, 2026 | Power train, axle assembly |
| 26V598000 | Sep 17, 2026 | Steering linkages, knuckle, spindle, arm |
The 2024 Grand Highlander's four earlier campaigns cover side curtain airbags, an instrument-cluster issue, a back-over-prevention display and vehicle labels. The 2025's three repeat the instrument-cluster and back-over-prevention campaigns and add a second labeling recall. Neither year lists the steering knuckle.
Do the Lexus TX and Lexus RX share this recall?
Yes. RideTruth's own recall records for both cars list 26V598000 directly. The 2026 Lexus TX has 5 NHTSA campaigns on file, and the 2026 Lexus RX has 3; the steering-knuckle campaign is one of them for each. That matches NHTSA's own record, which names TX350, TX500 Hybrid, RX350, RX350 Hybrid and RX500 Hybrid alongside the Grand Highlander and Grand Highlander Hybrid as sharing this campaign.
If you own a 2026 Grand Highlander, Lexus TX or Lexus RX, save it to your garage and RideTruth flags 26V598000, or any recall filed after it, the next time you check back.
