Tell What Car? about your car for this year's Reliability Survey and you could win £250

New cars are gaining ever more complex safety and connectivity technology, from automatic emergency braking systems to online concierge services that can check where you are going and book you a parking space for when you arrive.

That means there are more things than ever to potentially go wrong, which is why Autocar's sister site What Car? is inviting your contributions to its annual Reliability Survey. To thank you for taking part, you’ll be entered into a prize draw to win a £250 Amazon voucher. 

The aim is to gather information about the dependability of as many car models as possible and share this with car buyers to help them make the most informed buying choices.

If your car has suffered a fault in the past year, tell What Car? which of 15 different areas was affected, how long the car was out of action and, crucially, how much it cost to be fixed. This information is used to create a unique reliability rating for each model. 

The 2020 What Car? Reliability Survey contains data on 175 models from 31 car brands. Complete the 2021 survey now to help us gain ratings for even more car models.

I bought a brand new Mazda MX-5 on the strength of these kind of surveys but the car, dealership and Mazda UK were all terrible.

My wife bought a new Skoda Octavia after noticing it did well in surveys too but once again, awful build and reliability soured that ownership experience.

I suppose on average you're more likely to have a better chance of buying a more dependable car from reading these surveys, but in our (admittedly unlucky) experiences, they actually steered us towards cars that were rubbish (and away from cars that might have fared better for us).

Prediction: top ten reliability will be Japanese, or Korean Bottom 10 will be european or American. Thats all you need to know.
