The quarterly Warranty Direct ‘Reliability Index’ looks at the number of breakdowns and cost of repairs for all major manufacturers.
Each is then given a score with the lower numbers signifying a more reliable brand. Chevrolet topped the survey with a score of 20 – ten less than previous winners Honda.
It is also the cheapest brand to fix, with average repairs costing over £40 less than its nearest rival at £195.14 per claim.
Warranty Direct’s Managing Director, Duncan McClure-Fisher, said: "Honda has held the top spot in our overall manufacturer’s reliability table for many months, so for Chevrolet to knock them off their perch is a major coup."
Chevrolet made it a hat-trick of awards after data showed the manufacturer had the shortest ‘time-off-the-road’ when repairs were being done.
Chevrolet UK Managing Director, Mark Terry said: "It’s a real testimonial to the quality and reliability of our vehicles that we’re leading the Reliability Index. But more than that, the finer data such as time of repair and average repair costs goes to show that our passion for providing customers with real-world value goes beyond the initial purchase of the car."
Chevrolet, which sells the Spark, Aveo, Cruze and Captiva in the UK, has recently launched the new seven-seat Chevrolet Orlando MPV, its first people carrier for the European market since the brand was re-launched in 2005.
Chevrolet currently offers a ‘Five-Year Promise’ with all of its cars sold in Europe. The five-year warranty includes roadside assistance, servicing, MOT insurance and vehicle health checks at a Chevrolet dealership.
Elsewhere in the index, Fiat was the second least expensive car to repair on average, a testament to its range of small cars and availability of parts.
