GWM Haval H6 2022 Problems

The best advice here is to disconnect the battery and contact the dealership. Any time there’s odd electrical behaviour combined with a burning smell, there’s a decent chance you have an electrical short-circuit on your hands. And that can easily lead to a fire that could destroy the car and anything near it.

By disconnecting the battery, you’re removing the power source that is making something hot enough to produce the burning smell. The constant beeping, meanwhile could be a symptom of the same thing as the shorted or damaged wiring allows the warning beeper to continue blaring away even though the ignition is turned off.

This occurs more often than you think and it’s often caused by overtightening of the sump plug when the old oil has been drained out and the new stuff is ready to go in. Generally speaking, the sump plug will be screwing into either a thin metal oil pan or a rather soft alloy sump. Either way, too much torque on the spanner that tightens it can easily strip the treads and leave you stranded. This is far from just a Haval problem – many makes and models have suffered the same fate.

The fix is usually to get the vehicle to a workshop where the mechanic can either drill out the messed up threads and cut a new thread to take an oversized sump plug. Done carefully, this can often be achieved without removing the sump.

Although it’s an inconvenience to lose your car for any length of time, it might be the only way the service team can diagnose the problem and attempt a fix. We like to remind each other that car makers have obligations under consumer law, but it also pays to remember that, as the consumer, you also need to give the manufacturer the opportunity to put things right if it can.

The best solution would be for the dealer to provide a courtesy car while yours is in dry dock.

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.
