Mazda CX-90 Under Federal Investigation After Recall Fails to Fix Sticky Steering
Mazda recalled the 2024 CX-90 in early 2024 to address a "sticky steering" defect—a sudden, unexpected increase in steering effort that could catch drivers off guard, especially at highway speeds . Nearly two years later, the National Highway Traffic Safety Administration (NHTSA) has launched a new investigation after 26 drivers reported the same problem in vehicles that had already been repaired . Two crashes have been linked to the issue . Here's everything you need to know.
The Original Recall: What Mazda Tried to Fix
In January 2024, Mazda issued Recall 24V022 affecting approximately 44,000 2024 CX-90 SUVs . The problem: excessive friction in the worm gear inside the electric power steering system .
How it works: The worm gear distributes power assistance from the steering motor. When friction builds up, the steering wheel can suddenly become harder to turn—a phenomenon NHTSA describes as "sticky steering" . The defect was traced to a faulty spring inside the gear, supplied by Hitachi .
Mazda's fix: Dealers replaced the spring with an upgraded unit, applied fresh lubricant, and installed a software update designed to detect the problem before it occurred . On paper, it seemed like a permanent solution.
The Investigation: Why Regulators Are Looking Again
The NHTSA's Office of Defects Investigation (ODI) launched Recall Query RQ26002 on January 26, 2026 . The investigation covers 43,752 model-year 2024 CX-90s sold in the U.S. .
"After receiving the recall 24V022 remedy, consumers report sudden increases of steering effort while driving," NHTSA wrote in its announcement . "Sudden and unexpected change of steering effort while driving may increase the risk of a crash."
Notably, Mazda previously stated that CX-90 owners would receive no warning before experiencing this issue .
Two Crashes, No Injuries
The investigation documents confirm two crashes possibly linked to the steering defect . However, regulators have no record of injuries or deaths resulting from the problem .
The crashes occurred after the recall repairs had been performed, raising serious questions about whether Mazda's fix actually addressed the root cause .
Timeline of Events
Investigation Scope and Key Questions
The Technical Issue: Worm Gear Failure
The defective component is a worm gear within the electric power steering system, supplied to Mazda by Hitachi . These gears are essential for distributing power assistance from the steering motor, providing the smooth, effortless steering drivers expect from modern vehicles .
In the CX-90, excessive friction in the worm gear—caused by a faulty spring—translates significant force back to the driver, making the steering wheel suddenly harder to turn . The problem can occur intermittently and without warning.
What Happens Next for CX-90 Owners
Current Status
At this point, owners don't need to take any immediate action . The NHTSA hasn't issued a new recall, and Mazda hasn't provided additional guidance .
Possible outcomes :
- The ODI determines the original recall was adequate → investigation closed
- The ODI finds the remedy insufficient → Mazda must issue a revised repair in a new recall
Regulators are evaluating both whether the 24V022 fix was effective and why steering abnormalities continue to occur after repair .
What Owners Should Do Now
Check your VIN: NHTSA.gov/recalls
- Monitor your steering: If you experience any sudden increase in steering effort—even briefly—document it .
- Report problems: File a complaint with NHTSA if you experience sticky steering after recall repairs .
- Stay informed: The investigation is ongoing; check for updates on NHTSA.gov or your Mazda owner portal.
- Safety first: If steering becomes difficult while driving, reduce speed gradually and find a safe place to stop .
Mazda's Response (So Far)
As of February 2026, Mazda North America has not issued a public statement regarding the new investigation . The company is expected to cooperate fully with NHTSA to determine the root cause and appropriate next steps .
