  • We haven't heard from enough Mirai owners to give it an accurate reliability rating. However, Toyota’s outstanding reliability is one of the brand’s biggest trump cards. It gets full marks in our reliability survey yet again – so if you want a car you can depend on, look to Toyota.81% of Toyota owners with a car aged less than three years told us their car remained fault-free in the past year, which is noticeably better than the average (75%).Among these owners of new cars, there was no single issue prevalent enough to be considered common. It’s a top result and means Toyota gets the full five stars for 0-3-year reliability.But where the real appeal lies is in the Japanese carmaker’s long-term dependability.Our survey reveals that three quarters of owners with a Toyota aged between three and eight years reported no faults with their car in the past year. That would be a good result among young cars, and is exceptional among this 3-8-year group. The breakdown rate is just 2.1%, less than half of the average in our survey. Of the very few who were unfortunate enough to experience an issue, faults were typically non-serious and quick to put right. Owners of faulty Toyotas, on average, only spent a couple of hours without their car in the year prior to our survey.Thanks to so many of its cars dodging the mechanic’s wrench, and the few that did have an issue spending very little time in the garage, Toyota gets another full five stars for 3-8-year reliability.How comfortable and spacious is it?
