Toyota leads hybrid reliability study with Corolla, Yaris and RAV4

New research from Warranty Solutions Group (WSG) has identified the UK’s most reliable hybrid vehicles, with Toyota models taking the top three positions.

The study analysed thousands of warranty claims submitted over the past 12 months across 20 of the most popular used hybrid models.

The Toyota Corolla Hybrid emerged as the best performer, with a claim rate of 1.32% and an average repair cost of £79.95. It was followed by the Toyota Yaris Hybrid with a 1.69% claim rate and £462.05 average repair cost, and the Toyota RAV4 Hybrid, which also recorded a 1.69% claim rate and £750.00 average repair cost.

At the other end of the scale, the Range Rover and BMW X5 were found to be the least reliable, with claim rates of 18.65% and 13.21% respectively, and average repair costs frequently exceeding £1,100 per claim.

Martin Binnee, operations director of Warranty Solutions Group, said: “These results clearly show that not all hybrids are created equal. Our claims data offers invaluable insight into the true ownership experience, not just brochure stats.

“Toyota’s dominance in the reliability rankings reflects decades of investment in hybrid technology, and it should give confidence to both dealers and consumers navigating a rapidly evolving automotive landscape. With electrified vehicles gaining ground in every market segment, warranty-backed peace of mind is more important than ever.

“This report enables the industry to make smarter, data-driven decisions – whether stocking forecourts, pricing warranties, or supporting customers long after the sale.”

The study also highlighted common hybrid faults, with battery issues accounting for 3.89% of all claims at an average cost of £260.08.
