The Which? Car Survey 2021 closed on 14 June 2021. The feedback you provided will help us find the most and least reliable cars you can buy, and contribute directly to how we rate cars. Thank you to everyone who took part.
Whether your car is a flawless angel or a dodgy motor dogged by issues, we want to hear about it in our annual surveys.
Why bother? Because while our in-depth lab tests reveal a car’s strengths and weaknesses, they won’t tell us what it’s like to live with – and that’s where you come in.
This means when the time comes to buy your next car, you can use our research to avoid an unreliable model that's going to leave you stranded at the side of the road.
Once results are in, we update:
Whether you’re buying a new car or something a little older, we can help you find a model you can rely on.
We dig as deeply as we can into each car’s track record, going back up to ten years. To make sure we rate cars fairly, we classify every fault we hear about as one of the following:
When manufacturers ask why a car has scored poorly in the survey, we share as much detail as we can to help them get to the root of a problem. So these results not only help us compare different cars, they also give carmakers a reason to keep evolving and improving their vehicles.
Satisfaction counts for an awful lot when it comes to customer loyalty. A happy owner is likely to buy another car from the same manufacturer and wholeheartedly recommend it to others.
That’s precisely why our survey asks owners to rate (out of five) how satisfied they are with their car, and also how likely they are to recommend it to a friend. By combining the responses to these two questions, we’re able to award each car a customer score as a percentage.
The previous car survey, the Which? Car Survey 2020, closed at 10:00am on the 24 February 2020. If you completed the survey, you not only helped us find the most reliable cars in the UK, but one lucky person won the big prize of £2,500.
It's not just car reliability the survey reveals - here are some interesting facts from the 2020 survey:
