The Lexus NX is consistently the top seller in its class, beating out comparable models from Mercedes-Benz. This isn’t just about brand preference; it’s about reliability and value. Buyers are actively choosing the NX over the Mercedes-Benz GLB, making it a clear winner in the subcompact luxury SUV segment.
Why Reliability Matters: A Shift in Buyer Behavior
Modern car buyers aren’t just focused on status symbols anymore. High maintenance costs and frequent repairs are major deterrents. The Lexus brand has cultivated a reputation for durability, and that reputation is translating directly into sales. The NX’s success demonstrates a growing trend: consumers prioritize long-term ownership costs over short-term prestige.
Lexus NX Sales Figures: A Consistent Lead
Last year, Lexus sold 74,488 NX units, exceeding all Mercedes-Benz competitors in the same category. Year-to-date figures (as of late 2025) show a continuation of this trend, with 62,808 NXs sold. In contrast, Mercedes-Benz has moved only around 7,296 GLB units this year. The difference is stark: the NX sold nearly three times as many units in just one quarter as the GLB did in the entire year.
This isn’t a new phenomenon. The NX has consistently outperformed its rivals for years, with 2023 sales increasing by 25,524 units over 2022. While the Lexus RX remains the brand’s overall best-seller (118,636 units in 2024), the NX holds its own as a dominant force in the subcompact luxury segment.
Reliability Scores: Lexus vs. Mercedes-Benz
The Lexus NX’s success isn’t just due to pricing or marketing. J.D. Power ratings consistently place Lexus above Mercedes-Benz in terms of quality and dependability. The 2025 NX scored 85 out of 100 in reliability, five points higher than the last Mercedes-Benz GLB evaluation from 2023. Lexus also ranks first in overall vehicle dependability, with only 140 problems reported per 100 vehicles, compared to Cadillac’s 169 and Porsche’s 186.
Pricing and Value: A Competitive Edge
The base 2025 Lexus NX 250 starts at $41,965 (including fees), while the entry-level Mercedes-Benz GLB begins at $45,800. The NX also offers hybrid options, with pricing ranging from $46,275 to $63,480 for higher trims. This competitive pricing, combined with superior reliability, makes the NX an attractive option for budget-conscious luxury buyers.
Beyond Sales: The NX’s Strengths and Weaknesses
While the NX dominates in sales and reliability, it doesn’t necessarily offer the most engaging driving experience. Competitors like the BMW X1 and Mercedes-Benz GLA provide sharper handling and a more sporty feel. However, for buyers prioritizing dependability and long-term value, the Lexus NX remains the clear choice.
The Lexus NX’s success isn’t just about numbers; it’s a testament to the brand’s commitment to quality and reliability, qualities that are increasingly valued by modern car buyers.
The NX continues to prove that in the luxury SUV market, dependability matters just as much as prestige.
