My Car is a 2018 Hyundai Kona. I have a speed-reading error of 7 km/h under, as with 60 km/h reading but only 53 km/h true speed. I have contacted Hyundai Australia for information on the warranty of above error and after 35 minutes on hold the reply was it is up to my local Hyundai dealer to look at the problem. My local Hyundai dealer looked at the car and told me it cannot be fixed. Is it a Hyundai common problem?
Ah, the perennial fast speedo! It’s a problem that affects every car on the road, as carmakers are not allowed to make a speedo that is slow. But it is allowed to sell a speedo that is fast, at least within a specified tolerance. It can’t simply be fixed, you have to put up with it. Presumably you have an alternative device that gives you a more accurate speed-reading and you should rely on that.
