Knowing which dash cam brands develop the most faults means you can avoid buying a dash cam that's likely to let you down.
That's why each year we ask more than 10,000 Which? members to tell us whether they're happy, or have experienced problems, with their tech products in our unique reliability survey.
Our survey data takes into account the fault rates reported by their owners, plus the severity of these faults and how soon they occurred after being bought.
In our latest analysis, we've looked at the performance of the biggest dash cam manufacturers – Garmin, Halfords, Nextbase and Transcend. We've calculated a reliability rating for each brand so you know which brand to choose to find the best model and which to avoid.
Our survey data allows us to report on four major dash cam brands – Garmin, Halfords, Nextbase and Transcend. As you can see from our table below, there's a noticeable difference between the best and worst brands.
|Best and worst test scores from these four brands||76%||50%|
|Customer satisfaction score||79%||66%|
In the table brands are ranked by their customer score. A high customer score means that owners in our survey would recommend their dash cam. The more stars for reliability, the fewer the problems reported.
|Brand||Reliability rating||Reliability score||Customer score|

Our survey shows that if you experience a problem, it's likely to be a fault where the dash cam refuses to record.
Some 11% of dash cam owners in our survey reported that they encountered an issue where footage would not record on their dash cam, which essentially renders the it useless.
The least reliable brand identified in our survey didn't fare so well – 17% of owners reported a fault on one-year-old devices, an astonishingly high figure.
Our most reliable dash cam brand ages far better – only 7% of owners reported a fault on their four-year-old devices.
The top-performing dash cam brand in our survey finished up with a reliability score of 94%. The worst performer has a score of 84%.
The graph shows how the brand that stays fault-free for the longest compares with the worst brand and the overall average.
|Most reliable brand||Average||Least reliable brand|
|% of products faults free after year 1||93%||88%||83%|
|% of products faults free after year 2||93%||86%||83%|
|% of products faults free after year 3||93%||85%||83%|
|% of products faults free after year 4||93%||85%||83%|
|Brand name||% faults after one year||% faults after four years|

Which? has a wealth of information on the UK's favourite technology brands.
Every year, we ask Which? members to tell us about the technology products they own – from how likely they would be to recommend a brand to how reliable the products are once they get them home.
This year, nearly 10,000 Which? members told us about more than 33,000 devices. We calculate a brand's reliability and its customer score based on the results of our annual survey.
This data is crucial for our testing, too. If a brand falls far below the category average, we remove a manufacturer’s Best Buy and won’t recommend any of its products unless a marked improvement in reliability is shown.
