The main reasons for the lack of power when stepping on the accelerator in Haval H6 are as follows: 1. Carbon deposit issues. 2. Fuel system problems. 3. Intake system problems. 4. Clogged fuel injectors. 5. Fuel pipe leakage. 6. Reduced fuel pump power, clogged fuel filter, etc. Below is an introduction about the Haval H6: The Haval H6 uses two engines across its lineup, one being a 1.5-liter turbocharged engine and the other a 2.0-liter turbocharged engine. The 1.5-liter turbocharged engine has a maximum power of 169 horsepower and a maximum torque of 285 Nm, with the maximum power speed ranging from 5000 to 5600 rpm and the maximum torque speed ranging from 1400 to 3000 rpm. The 2.0-liter turbocharged engine has a maximum power of 224 horsepower and a maximum torque of 385 Nm, with the maximum power speed at 5500 rpm and the maximum torque speed ranging from 1600 to 3600 rpm.
When driving my Haval H6, I've experienced a soft and unresponsive throttle, which is usually related to the engine not getting enough air. First, check if the air filter is clogged with dust—this part can suffocate the car if not replaced every six months. If the spark plugs are worn out and misfiring, the throttle may also feel weak; I had this issue last time when I didn’t replace them at 40,000 km. If these are fine, suspect a turbocharger pipe leak or insufficient fuel supply from the fuel pump, especially in older cars where fuel lines tend to accumulate carbon deposits. Also, check if the brakes are slightly stuck—if the wheels don’t rotate freely, the car will naturally struggle. Don’t skimp on fuel by going to small gas stations, as low-quality gasoline with impurities can severely damage the fuel system.
