Do you believe simpler vehicle technology is more reliable than advanced modern digital features?

Lexus has refreshed the 2026 IS sedan, incorporating dual 12.3-inch touchscreens and updated steering and suspension systems. The automaker continues to utilize the 3.5-liter 2GR-FKS V6 engine to focus on long-term vehicle reliability.

Why it matters

Lexus intentionally limited advanced onboard technology and maintained its naturally aspirated engine to minimize potential software errors and mechanical bugs. This strategy aims to uphold the brand's reputation for dependable performance in an industry increasingly prone to connectivity-related glitches.

The 2026 model retains a 3.5-liter V6 engine producing 311 horsepower, a power unit that debuted in 2014. The vehicle eschews over-the-air update capability, which currently contributes to an industry-wide average of 24.2 problems per 100 vehicles due to connectivity.
