Reliability is a key factor when choosing a car, and owners expect their vehicles to perform well over time. However, according to the Honest John Satisfaction Index, some cars fail to meet these expectations. Based on feedback from 6,000 car owners, this list reveals the ten least reliable cars on the market. Interestingly, five of the models belong to premium brands, challenging the perception that high-end cars are more dependable. Let’s take a closer look at the worst-performing models in terms of reliability.
1.Mercedes-Benz GLC (2015-2022) – The Biggest Disappointment
With an average reliability score of just 8.52, the Mercedes-Benz GLC is the worst-rated car on this list. As a luxury SUV that competes with the BMW X3 and Audi Q5, owners expected more from the brand. Unfortunately, frequent breakdowns, high repair costs, and general dissatisfaction place the GLC at the bottom of the rankings. The model has even been named the least satisfying car to own in the UK.
2. Peugeot 3008 – Style Over Substance
The Peugeot 3008 is well-regarded for its stylish design and enjoyable driving experience. However, its reliability score of 8.61 suggests that it falls short in terms of durability. Owners have reported issues with build quality and high fuel costs, making it a costly choice in the long run. Despite its popularity among families, reliability concerns significantly impact owner satisfaction.
3. Ford Kuga – Costly Repairs and Frequent Issues
The Ford Kuga is another SUV that fails to impress when it comes to reliability. With a score of 8.70, it ranks among the least dependable vehicles in the UK. Owners cite frequent breakdowns and expensive repair bills as major drawbacks. Given Ford’s reputation for producing reliable vehicles, the Kuga’s poor performance in this index is a significant letdown.
4. Land Rover Discovery Sport – Improvement, But Still Unreliable
The Land Rover Discovery Sport fares slightly better than before but still disappoints in reliability. With an average score of 8.91, it remains plagued by engine problems and build quality concerns. While Land Rover has made some improvements, owners continue to report frequent mechanical failures, making it a risky purchase for those seeking dependability.
5. Skoda Octavia (2013-2020) – Practical Yet Problematic
The Skoda Octavia is known for being spacious, comfortable, and affordable, but its reliability is a weak point. Scoring 8.91, the model from 2013 to 2020 has suffered from gearbox issues, particularly with its DSG automatic transmission. Despite its many positive attributes, this problem alone significantly affects its overall rating in the Satisfaction Index.

6. Mercedes-Benz C-Class (2014-2021) – Expensive to Maintain
Another luxury car to make the list, the Mercedes-Benz C-Class, scores 9.05 in reliability. Though it remains a popular choice in the UK, owners report frequent mechanical failures and costly repairs. Given the brand’s premium status, many buyers expect better build quality, making its place on this list particularly surprising.
7. Nissan Qashqai (2014-2021) – A Popular Model with Reliability Woes
The Nissan Qashqai is one of the best-selling crossovers, but the pre-2021 model has serious reliability concerns. With an average score of 9.09, many owners have faced mechanical issues, adding to repair costs and frustration. The newer version aims to address these concerns, but the previous generation’s track record remains poor.
8. Ford Fiesta – A Declining Favorite
Once Britain’s favorite car, the Ford Fiesta’s reliability has taken a hit in recent years. Scoring 9.12, the model suffers from build quality issues, leading to dissatisfied owners. As the market shifts toward compact crossovers like the Ford Puma, the Fiesta’s reliability struggles have contributed to its waning popularity.
9. Volvo V40 (2012-2019) – Outdated and Unreliable
Volvo’s small hatchback, the V40, is no longer in production, and its reliability score of 9.13 explains why. Owners have faced multiple issues with durability and performance, making it one of the least dependable models in the Satisfaction Index. Fortunately, its successor, the XC40 SUV, has received much better feedback.
10. BMW 3 Series – Premium Look, Subpar Reliability
Closing out the list is the BMW 3 Series, which scores 9.20. Despite its reputation for sporty performance and luxury, this model has been criticized for poor build quality. Owners also report dissatisfaction with ride comfort, earning it a below-average score in overall satisfaction. For a premium sedan, these issues are particularly disappointing.
Reliability is a crucial aspect of car ownership, and these ten models have failed to meet expectations. Whether due to high repair costs, mechanical issues, or poor build quality, each car on this list has left owners frustrated. While premium brands like Mercedes-Benz and BMW often promise top-tier quality, their presence on this list proves that luxury does not always equate to dependability. Before purchasing a vehicle, potential buyers should consider long-term reliability and not just brand reputation.
