GWM Haval H6 Problems

Plenty of owners of cars (not just Havals) with this type of 'intelligent' cruise-control have complained about it. The problem occurs at highway speeds on any road with a corner on it. At which point, the vehicle decides it's travelling too fast and slows down, sometimes actually applying the brakes. Depending on whether you simply want a comfortable journey or you've just overtaken a B-double, this can be anything from annoying to dangerous.

I've heard reports of Haval dealers having a software upgrade which can be uploaded to the car during a service which eliminates this element of the adaptive cruise-control. It would be worth asking your Haval dealer whether it's available yet.
Some owners have actually resorted to physically covering the front camera so the car no longer knows there's a corner approaching. We definitely don't recommend that as it might interfere with other safety features.
