Common Issues with the Haval H9
The Haval H9 is a reliable and capable vehicle, but like any SUV, it can have its issues. Some of the most common issues with the Haval H9 include tire pressure monitoring system (TPMS) warning light, electrical problems, poor fuel economy, rear differential noise, check engine light and OBD II diagnostics, engine coolant leaks, valve cover gasket leaks, transmission issues, exhaust system problems, alternator troubleshooting and replacement, and radiator troubleshooting and replacement. It’s important to be aware of these common issues so that you can take the necessary steps to ensure your Haval H9 performs at its best.
Tire Pressure Monitoring System (TPMS) Warning Light
The Haval H9 is equipped with a Tire Pressure Monitoring System (TPMS) which is designed to alert the driver of any changes in the tire pressure. If you notice the TPMS warning light illuminated on the dashboard, it is important to check the pressure of all tires and adjust it accordingly. Additionally, you may need to install a TPMS sensor for each tire to ensure accurate readings.

Electrical Problems with the Haval H9
Electrical problems are some of the most common issues with the Haval H9. There are a few possible causes for this, including a faulty battery, bad alternator, or corrosion of electrical components. It is also possible for the car’s computer to experience problems, which can lead to electrical issues. If you notice any flickering lights, dimming lights, or any other electrical issue, it is important to get it checked out so that it can be resolved as soon as possible.
Poor Fuel Economy
The Haval H9 is touted for its great fuel economy, but unfortunately, many owners have found that their vehicles are not meeting the 12.1 liter per 100km fuel economy rating. Poor fuel economy is a common problem with the Haval H9, and many owners have reported feeling cheated as they get significantly lower miles per gallon than what was advertised. Common causes of poor fuel economy include clogged air filters, damaged or worn spark plugs, faulty oxygen sensors, and a dirty or malfunctioning mass air flow sensor. Additionally, the Haval H9's automatic transmission can be prone to slipping or shifting too hard, both of which can cause poor fuel economy. To resolve this issue, check the vehicle’s transmission fluid level and condition and make sure it is clean and at the correct level. If the problem persists, you may need to have your transmission serviced or replaced.
Rear Differential Noise
The Haval H9 is known to have issues with its rear differential, which can cause a loud clicking or rumbling noise. This noise is usually caused by a worn or broken axle bearing or differential bearing, or a faulty differential gear. To diagnose this issue, you will need to raise the vehicle and inspect the differential. If you find any loose or broken parts, they should be replaced. Additionally, be sure to check the axle shaft seals and gaskets for any signs of leakage. If necessary, the entire differential assembly should be replaced.
Check Engine Light and OBD II Diagnostics
The Haval H9’s on-board diagnostics system can help you pinpoint what is causing the “check engine” light to come on. Using an OBD II scanner, you can read and clear stored trouble codes, as well as monitor live data from the vehicle’s sensors. This can help you narrow down the cause of the problem and find a solution. In addition, many shops have access to specialized diagnostic software that can provide additional information about your vehicle’s systems. If you are having trouble with your Haval H9, it is important to consult a professional mechanic or technician to properly diagnose and repair the problem.
Engine Coolant Leaks
Engine coolant leaks are a common issue with the Haval H9. The most common cause of engine coolant leaks is a worn or damaged gasket, seal, or hose. To diagnose this issue, you will need to access the engine and inspect the system for any visible signs of damage or leaks. You can also perform a Leakage Test, Engine Coolant Filling Mode, and BSD Radar ECG to help identify the exact source of the leak. Once identified, you will need to replace any worn or damaged components in order to fix the leak. It is important to follow the manufacturer's instructions when replacing any components to ensure a successful repair. Taking steps to properly maintain your engine coolant system can help to prevent coolant leaks in the future.
Valve Cover Gasket Leaks
The Haval H9 is equipped with a 2.0L engine and is susceptible to valve cover gasket leaks. If you are experiencing oil leaks from around the valve cover, it may be time to replace the gasket. This can be done yourself using an OEM replacement gasket, such as the Engine Cylinder Valve Cover and Gasket for Great Wall Haval H9 H8 H6 F7 Gasoline 2.0t Engine Gw4c20 Original from Alibaba.com. It is important to use the correct gasket for your particular engine to ensure a proper fit and seal. Be sure to also inspect and replace any other worn or damaged components, such as the spark plugs or valve cover bolts, before reassembling the valve cover.
Transmission Issues and Solutions for the Haval H9
The Haval H9 is equipped with an 8-speed automated manual gearbox, which can be a source of transmission issues. Common problems include shifting difficulties, transmission noise, and transmission fluid leaks. If your Haval H9 is experiencing any of these issues, you may need to have the transmission serviced or replaced. To diagnose and fix any transmission problems, you should have a certified mechanic inspect your Haval H9 to determine the cause of the issue. If the issue is related to the shift lock solenoid, then the solenoid will need to be replaced. Additionally, if there is an issue with the transmission fluid, it may need to be flushed and refilled. If any of the internal components are damaged or worn out, they may need to be replaced. Lastly, you should also check that all electrical connections are functioning properly and that none are loose or broken.
Exhaust System Problems and Solutions for the Haval H9
The Haval H9 is equipped with an exhaust system that needs to be maintained and monitored regularly. Common issues include clogged catalytic converters, mufflers, and tailpipes that may need to be replaced. Other problems include leaking exhaust manifold gaskets, broken exhaust pipes, and faulty oxygen sensors. To diagnose these issues, a mechanic should inspect the system for any damage or blockages and use a scan tool to check for any fault codes. The mechanic can then replace any worn or damaged parts as necessary. Regular maintenance of the exhaust system can help prevent major problems from occurring and ensure that the Haval H9 is running at its best.
Alternator Troubleshooting and Replacement on Haval H9
One of the most common problems with the Haval H9 is a faulty alternator. When the alternator fails, it can cause a variety of electrical and performance issues. Some of these issues include stalling, weak battery, dim headlights, and other electrical system problems. If your Haval H9 is experiencing any of these symptoms, then it may be due to a failing alternator.
In order to diagnose the issue, you should first check the voltage output of the alternator using a voltmeter. If the voltage is below 13 volts, then this indicates that the alternator is having trouble producing enough power.
If it is determined that the alternator is indeed failing, then you will need to replace it. Replacing an alternator on your Haval H9 can be a difficult task, so it is best to seek out professional help if you are unsure of how to proceed. The total cost of replacing an alternator on your Haval H9 can range from $400-$1000+, depending on the make and model of your vehicle.

The radiator is a key component in the cooling system of your Haval H9. If it malfunctions, it can quickly lead to engine overheating and damage. To avoid this, it’s important to regularly inspect your radiator to make sure it is functioning properly. If you notice that you are having difficulty keeping the temperature of your engine in check, it’s likely due to a malfunctioning radiator.
Fortunately, you can easily find high quality radiator assemblies online with free shipping and returns. With these, you can replace your old radiator with a brand new one. To make sure that the installation goes smoothly, make sure to get an OEM part that fits your car’s exact make and model. Additionally, you can refer to your Haval H9 owner’s manual for instructions on how to properly install a new radiator.
If you’re unable to do the installation yourself, you can always contact a certified mechanic for assistance. With their help, you can ensure that your radiator is correctly installed and running smoothly again.
