The National Highway Traffic Safety Administration (NHTSA) has launched an investigation into more than 43,000 units of the 2024 Mazda CX-90 after a previous safety recall fix potentially created steering problems. The initial recall aimed to address a faulty worm gear inside the steering system that could lead to random increases in steering effort. Despite the replacement of a spring with an upgraded unit, consumers have reported experiencing 'sticky steering' issues, which NHTSA describes as sudden and unexpected changes in steering effort while driving.
This has raised concerns about the potential risk of crashes. The investigation is focused on the same population of 2024 Mazda CX-90 units included in the initial recall. While the SUV's power steering remains functional, the increased effort required to steer may suddenly change without prior warning.
Mazda owners who experience this issue will receive no prior notification. Two crashes have been recorded in relation to this issue, highlighting the need for a more permanent solution. The investigation is not uncommon, as seen in General Motors' ongoing saga related to its L87 V-8 engines.

In this case, it appears that Mazda may be revisiting their engineering drawing board to address the issue. The NHTSA's actions demonstrate their commitment to ensuring road safety and protecting consumers. As the investigation unfolds, it is essential for Mazda to work closely with regulatory bodies to identify the root cause of the problem and implement a lasting fix.
This investigation highlights the importance of thorough testing and quality control in the automotive industry. The fact that a previous recall fix may have created new issues underscores the need for manufacturers to continually assess and improve their products.
