Buick: America's Oldest Car Brand is Now Its Most Reliable

Let's be real, when most people think of reliable cars, their minds don't immediately jump to American brands. We love our big trucks and classic muscle, but the conversation about long-term dependability has long been dominated by Japanese and Korean nameplates. Well, it's 2026, and the script has officially flipped. 🚗💨 The latest data isn't just promising; it's a full-blown paradigm shift. The most dependable American cars you can buy right now aren't from the flashiest startups or the truck giants—they're from Buick, the oldest continuously running American car brand in history. It’s like discovering your grandpa's favorite, timeless wool coat is suddenly the most high-tech, weather-proof garment on the market.

The 2025 J.D. Power Verdict: Buick Takes the Crown 👑

The proof is in the pudding, or in this case, the Problems Per 100 Vehicles (PP100) score from J.D. Power's 2025 U.S. Vehicle Dependability Study (VDS). This study measures problems experienced in the past 12 months by original owners of three-year-old vehicles. In a year where the industry average rose to a troubling 202 PP100 (the highest since 2009!), Buick posted an astonishing score of 143 PP100. This placed it:

• Second overall among all brands, trailing only Lexus (140 PP100).

• First overall among all mass-market brands.

• The most dependable American brand, period.

This isn't a fluke or a one-model wonder. Buick's core crossovers are winning where it counts for families:

• Encore GX: Ranked top three in the Small SUV segment.

• Enclave: Ranked top three in the Upper Midsize SUV segment.

Why This Reliability Win is a Big Deal in 2026

The context makes this achievement even sweeter. The study found that the biggest headaches in modern cars aren't engines or transmissions anymore—they're software and connectivity issues. For the second year in a row, Apple CarPlay and Android Auto problems were the #1 complaint. In an era where our cars are becoming rolling smartphones, Buick’s restrained, clean approach to cabin tech is paying massive dividends. It’s like they built a fortress with a simple, reliable drawbridge while everyone else was installing fancy, glitchy digital moats.

Let's look at how the other American brands stacked up in 2025:

Buick isn't just leading its GM siblings; it's lapping the competition from other domestic automakers. For shoppers who want an American badge with a premium feel but assumed they had to sacrifice peace of mind, Buick’s 2025 data is a game-changer.

This Isn't a One-Hit Wonder: A Half-Decade of Dominance 📈

The most compelling part? This is a sustained trend, not a lucky year. Buick's reliability has been building like a perfectly aged whiskey, getting smoother and more impressive with time. Here’s the track record:

• 2025: 143 PP100 (2nd Overall)

• 2024: 149 PP100 (2nd among mass-market brands)

• 2023: 159 PP100 (Top tier, 2nd in mass-market)

• 2022: 147 PP100 (2nd Overall in a redesigned study)

• 2021: 100 PP100 (Top 6 overall)

That’s five straight years of elite performance. It means if you buy a Buick, you're not betting on a single good model year—you're investing in a proven process and a corporate culture that prioritizes durability. This consistency is the golden thread in J.D. Power's data, pointing to systemic quality, not luck.

The Secret Sauce: History, Strategy, and Smart Engineering 🧠

So, how does America's oldest car brand become its most reliable? It’s a blend of legacy and modern strategy.

1. Deep-Rooted Engineering DNA: Founded in 1899, Buick's origin story is General Motors' origin story. Its early reputation was built on robust engineering, like the valve-in-head engine. That foundational focus on substance over flash never fully left the brand's ethos.

2. A Simplified, Focused Lineup: Buick wisely pivoted to a crossover-only lineup in the U.S.—Encore GX, Envision, Enclave, Envista. Fewer models mean more focused engineering resources and higher quality control. It’s the automotive equivalent of a master chef perfecting a small, exquisite menu instead of running a chaotic buffet.

3. Global Scale with Local Refinement: Buick is massive in China. That global volume keeps the brand financially healthy and fuels R&D, which benefits the vehicles sold here. It allows for investment in quality without relying solely on U.S. sales.

4. Tech Restraint: In an age of buggy, over-complicated infotainment systems, Buick's simpler interfaces seem to avoid the connectivity gremlins that plague other brands. Fewer problems reported = a better PP100 score.

What This Means For You, The Car Shopper in 2026 🛒

Whether you're buying new or used, this reliability data is powerful.

• New Car Buyers: You can confidently walk into a Buick showroom knowing you're choosing a brand that consistently tops American reliability charts. The warranty is great, but needing to use it less is even better.

• CPO/Used Car Shoppers: This is HUGE. The J.D. Power VDS studies three-year-old vehicles. So if you're looking at a 2023 or 2024 Buick Encore GX or Enclave, you're looking at vehicles from model years that contributed directly to these top-tier scores. That certified pre-owned Buick just got a lot more appealing.

• The Perception Shift: It’s time to throw out the old stereotype that American cars can't match Japanese rivals for long-term dependability. Buick is literally doing it, year after year. They are the quiet, steady metronome keeping perfect time in an orchestra of unreliable noise.

The Bottom Line

In 2026, the narrative around American car reliability has a new hero. Buick, the brand your grandparents might have loved, has quietly executed one of the most impressive quality turnarounds in the industry. It combines its historical legacy of solid engineering with a modern, focused product strategy to deliver crossovers that families can genuinely trust for the long haul. When the data speaks this clearly, it’s worth listening. The oldest American car company isn't just resting on its history—it's building the most dependable future on the road today. ✨
