Recent findings from Autotrader have shown that two-thirds of British drivers often misinterpret the noises their cars make, potentially costing up to £400 in unnecessary repairs. The survey involved 2,000 participants, testing their ability to recognize common mechanical issues from audio cues, with 66% failing to accurately diagnose problems ranging from basic brake wear to major engine faults.
Despite over half of the respondents feeling confident about their ability to identify these sounds correctly, there remains a significant discrepancy between their perceived and actual diagnostic skills. This gap not only endangers their safety but also leads to hefty repair bills when initially minor issues become major.

The study also highlighted that the most challenging sounds for drivers to identify were related to low power steering fluid and damaged wheel bearings—both of which are critical for safe driving. Alarmingly, 72% of the survey participants mistook the sound of a seized engine for a less severe issue like a worn wheel bearing. Interestingly, younger drivers aged between 25 and 35 were more confident in their car troubleshooting skills compared to those over 55.
The consequences of ignoring unusual noises from a vehicle proved financially significant as well, with a third of drivers admitting to overlooking such issues, which later escalated into more severe problems, adding an average of £400 to repair costs. About 20% of these cases resulted in repair bills exceeding £700.
Erin Baker, Editorial Director at Auto Trader, emphasized, “This research indicates that even confident drivers can be perplexed by unexpected noises. Addressing any unusual sounds early can not only maintain the vehicle’s resale value but also substantially reduce repair costs.”
The survey also uncovered that responses varied significantly among different car brands. Owners of Mercedes-Benz were quickest to address issues, whereas Audi owners were the most laidback, with nearly 29% willing to wait over a week before seeking help.
