Global supply chains are not without their challenges. Events like natural disasters, trade disputes, or pandemics can disrupt the flow of parts and delay production. For instance, during the 2011 earthquake in Japan, many automotive plants—including Tahara—were temporarily shut down, affecting global supply.

To mitigate these risks, Lexus employs a strategy called “multi-sourcing,” where critical parts are sourced from multiple suppliers in different regions. This reduces dependency on any single source and helps maintain production even during disruptions.

Additionally, Lexus uses advanced forecasting tools to predict demand and adjust production schedules accordingly. This helps prevent overproduction and ensures that vehicles are available when customers want them.

Quality Control: The Lexus Standard

One of the reasons the Lexus RX 350 is so highly regarded is its unwavering commitment to quality. From the moment a vehicle is conceived to the day it’s delivered to a customer, every step is monitored and optimized for excellence. This starts with design and engineering, where Lexus uses computer simulations and real-world testing to refine every component.

During production, quality control is integrated into every stage. At the Tahara plant, for example, robots perform precise welding and painting, while human inspectors check for imperfections. Each vehicle undergoes a series of tests, including road simulations, noise level checks, and alignment inspections.

Lexus also employs a system called “Genchi Genbutsu,” which means “go and see for yourself.” This philosophy encourages managers and engineers to visit the production floor, observe processes firsthand, and identify areas for improvement. It’s a hands-on approach that keeps quality at the forefront.

The Final Inspection

Before an RX 350 leaves the factory, it goes through a final inspection that can take several hours. Technicians check everything from the alignment of the doors to the responsiveness of the infotainment system. Even the smallest detail—like the sound of the turn signal or the feel of the gear shifter—is evaluated.

If any issue is found, the vehicle is sent back for correction. Only when it passes every test is it approved for shipment. This level of scrutiny ensures that every Lexus RX 350 meets the brand’s high standards.
