It’s not uncommon for owners of new vehicles with dual-clutch transmissions and throttle-by-wire to technology to feel a bit at odds with the way the car behaves. The feeling of a stilted, hesitant operation mirrors your experience to some degree. Over time, this sensation can be reduced. But it sounds as though your experience is a bit more dramatic than the norm.

In the first instance, give the dealer the opportunity to check the car out and make it right if there’s a problem. Modern vehicles like this can be scanned and the operation of their major functions graphed to show whether they’re within tolerance or not. There may be a software 'patch' in the works at Haval to address this.

If that doesn’t satisfy you, you can contact Haval Australia’s customer service department and lodge a complaint. Finally, if none of that does any good, you can contact the ACCC as a car sold brand-new that is not fit for purpose falls within the commission’s sphere of influence. You may find an independent test report of the vehicle’s behaviour would be a handy thing to have if you go down this route.

A $200 aftermarket throttle controller may, indeed, produce a vehicle you are happier to drive, but you should definitely check with Haval first to see if there are any warranty concerns in fitting such a device. Some advertisers of these devices claim there is no warranty issue, given that Haval would need to prove the throttle controller was the cause of any mechanical issues in the future. We’d still check with Haval before committing, however.
