What causes the Haval M6 to not accelerate?

[OBarrett]

The main reasons for not being able to accelerate are the throttle pedal sensor and the engine control unit (ECU) issues. Throttle Pedal Sensor Problem: The throttle pedal sensor is used to detect how much the accelerator pedal is pressed. The engine control unit uses this signal to control the engine's power output. When the throttle pedal sensor fails, the engine control unit cannot receive the throttle signal, resulting in the vehicle not moving when the accelerator is pressed. Solution: Replace the throttle pedal sensor. Engine Control Unit (ECU) Problem: The engine control unit can precisely control the engine's air intake, fuel injection, and ignition based on the driver's demand. When the engine control unit malfunctions, it can cause the vehicle to not move when the accelerator is pressed. Solution: Replace the engine control unit.

My Haval M6 also had a power loss issue before, where stepping on the gas pedal felt weak and sluggish. It could be a faulty fuel pump, preventing fuel from being delivered properly—replacing it might solve the problem. Alternatively, clogged fuel injectors can cause uneven fuel spraying. If the air filter hasn’t been replaced for too long, it restricts airflow, starving the engine. Another common cause is poor fuel quality; using low-grade gasoline affects combustion efficiency. Last time I took it to the repair shop, the mechanic said minor issues left untreated can damage the engine over time, wasting fuel and harming the car. It’s important to develop good driving habits, avoiding sudden acceleration, and sticking to regular maintenance. If something feels off, it’s best to consult a professional mechanic early—safety comes first.

I've seen plenty of cases where the Haval M6 lacks acceleration power. The most common issue is fuel system obstruction - like a clogged fuel filter restricting flow, or a faulty fuel pump causing insufficient delivery. Thick carbon buildup in the intake system (especially the throttle body) can also restrict airflow and reduce engine efficiency. My own vehicle had this problem two years ago - replacing the filter made a noticeable difference. Don't ignore it; prolonged driving with this condition increases fuel consumption and engine wear. I recommend immediate inspection starting with the simplest component (the filter), then checking the pump or sensors if needed. Developing regular maintenance habits saves both headaches and money - don't wait until a roadside breakdown causes bigger trouble.

Several possible reasons for the Haval M6's acceleration issue. The most common is insufficient fuel supply due to a faulty fuel pump, followed by uneven injection from clogged fuel injectors. Alternatively, weak combustion could result from ignition system failure caused by aged spark plugs. ECU control errors or oxygen sensor problems may also affect power. My recommendation is to first use diagnostic tools to read trouble codes for problem identification, then proceed with targeted repairs. For regular maintenance, avoid using low-quality gasoline and replace the air filter promptly.

Friend, you really need to pay attention to the refueling difficulty with your Haval M6. This situation is most likely caused by ignition system issues, such as old spark plugs failing to ignite; or a clogged fuel line with a dirty filter. I remember once my neighbor's car had the same problem, and it turned out to be a faulty fuel pump. Driving without timely repairs is dangerous, especially when you suddenly lose power on the highway. Quickly take it to a reliable repair shop, don't risk delaying it. Drive gently in daily use and perform regular maintenance to prevent potential hazards.
