I had a frightening experience in my 2017 Hyundai Accent Sports Hatch in January on the diamond-grooved section of the Hunter Expressway in NSW. Approaches to Hyundai dealers, "Customer Care" head office, NRMA, and RMS produced a variety of responses. My local dealer suggested that it was a combination of the tyres, the wheelbase, the carâs weight and suspension, but no solution. The RMS confirmed this and only advised that I adjust my speed to reduce the effect. I tried this yesterday on another trip, reducing speed to 70 km/h in a 110 km/h zone. Little difference. No satisfaction from Hyundai despite two thorough checks at two different dealer service centres.

What's wrong with my car?

You don’t tell us what happened, which makes it difficult to be of help.

Reducing speed isn’t a satisfactory answer, as driving at 70 km/h when the rest of the traffic is doing 100 km/h can be dangerous. It would appear that there is nothing obviously wrong with the car, or it would have been found in the inspections. You could try increasing the tyre pressures by 5 psi and see if that has any affect; you could also have an experienced mechanic drive the car over the section of road in question so they can see how it behaves.
