Car reliability is one of the most sought-after qualities for buyers, yet it remains notoriously difficult to measure. The veteran magazine What Car? has released its 2026 reliability survey, polling 30,000 drivers, and the results reveal that three German cars and one French model are among the least reliable vehicles on the market.
What the 2026 What Car? Reliability Survey Found
The survey asked drivers to report faults and issues with their vehicles over the past year. While the top of the rankings is dominated by Asian models, the bottom is surprisingly crowded with European names. The Volkswagen Tiguan (2024 onwards) took the dubious top spot as the least reliable car, followed by the Renault Arkana (2018-2025) and the Mercedes GLE.
In fourth place, another Volkswagen—the ID 4—appears, making it a strong showing for the German brand in the wrong direction. The first-generation Tiguan (2016-2024) also reappears in eighth place, highlighting persistent issues across model generations.
The Most and Least Reliable Models
At the other end of the spectrum, two cars share the top spot as the most reliable: the Mini Countryman and the Suzuki Swift (2017-2024). They are followed by the Toyota Aygo X, BMW 4 Series Coupé and Convertible, and the Mini hatchback.
The top 20 list is largely populated by Asian brands, known for their strong reliability records. This contrast with the bottom rankings underscores a shift in consumer perceptions and manufacturer priorities.
Why These Results Matter for Car Buyers
Reliability directly impacts ownership costs, safety, and peace of mind. A breakdown can lead to expensive repairs and inconvenience. For buyers, these rankings serve as a crucial guide when choosing a new or used car.

The poor performance of several European models—especially the Volkswagen Tiguan and ID 4—raises questions about quality control and long-term durability. It also challenges brand loyalty and the assumption that German engineering always equals reliability. The background to this story is set out in Car: latest articles.

What to Watch Next
As the automotive industry shifts towards electric vehicles, reliability will remain a critical factor. The 2026 survey results may influence manufacturer strategies and consumer choices. Buyers should stay informed about ongoing developments and consider extended warranties for models with questionable reliability records. Earlier coverage in F1 Bahrain GP Software Glitch Causes Rain Chaos and Delay shows how the argument developed. A closer look at the same subject appears in Black Death's Four-Century Wave: What Really Happened.
For now, the message is clear: not all European cars live up to their reputation, and Asian brands continue to set the benchmark for dependability.
