Understanding common issues with your GWM Cannon-X can save you time and money. This guide shares real problems I’ve seen in my workshop. The Cannon-X is a solid ute that offers great value. But like any vehicle, it has some weak spots you should know about.
I’ve worked on dozens of these trucks since they hit the market. Let me walk you through the main concerns owners bring to my shop.
Introduction to GWM Cannon-X
Great Wall Motors launched the Cannon-X in 2021. It quickly became popular in places like Australia. The truck offers modern technology at a fair price. People love it for weekend trips and outdoor adventures.
From my experience servicing these vehicles, I’ve noticed patterns. Some problems show up more often than others. Knowing these issues helps you catch them early.
The good news? Most problems are fixable. Regular care goes a long way. Let’s look at what I see most often in my bay.
Most Reported Problems
After working on many Cannon-X trucks, here are the main complaints:
Diesel Filter Blockages This tops my list. The filter gets clogged faster than expected.
Steering Feel and Response Drivers don’t like how the wheel feels. It’s heavier than they expect.
Screen and Tech Bugs The dashboard screen freezes or acts weird.
Rough Ride Quality Some owners feel too much shaking through the seat.
Higher Fuel Use Than Expected The truck drinks more fuel than the sticker says.
Let me break down each problem with real detail.
DPF Filter Concerns
The diesel particulate filter is my most common service call. This part traps soot from your exhaust. When it fills up, your truck suffers.
In my shop, I see this problem weekly. Short trips around town don’t let the filter clean itself. It needs highway driving to burn off the buildup.
Poor fuel quality makes it worse. So does skipping oil changes. The filter can’t do its job properly.
Warning Signs
Watch for these symptoms:
- Yellow warning light shaped like a filter shows up
- Your fuel gauge drops faster than normal
- Black smoke pours out when you press the gas
- The truck feels sluggish and weak
- Power drops when climbing hills
How to Check It
Here’s what I do when a Cannon-X comes in:
I plug in my diagnostic scanner first. Look for codes starting with P242 or P244. These point to DPF trouble.
Next, I check the filter itself. A visual inspection shows if it’s cracked or damaged.
I test the exhaust backpressure. High pressure means the filter is blocked.
Always verify the fuel is clean. Bad diesel causes many DPF failures.
My Fix: Force a regeneration cycle using my scan tool. If that doesn’t work, the filter needs cleaning or replacement.
Power Steering Complaints
Many drivers tell me the steering feels odd. It’s not smooth like newer trucks. The wheel takes more effort to turn.
I’ve heard grinding sounds from the steering rack. Some trucks pull to one side. This isn’t just annoying—it’s dangerous at highway speeds.
From years under the hood, I know steering problems don’t fix themselves. They get worse over time.
Warning Signs
Your Cannon-X might have steering issues if:
- The wheel shakes in your hands
- Turning takes too much muscle
- You hear whining when you turn
- The truck drifts left or right
- Steering fluid looks dark or dirty
How to Check It
When I service a truck like this, I start simple:
Pop the hood and check the power steering reservoir. Low fluid is an easy fix.
Take the truck for a test drive. Listen for any strange noises. Squealing usually means a worn belt or pump.
Get under the vehicle and inspect the steering rack. Look for fluid leaks or damaged boots.
Check all steering linkage for play or looseness.
My Fix: Most times it’s low fluid or a bad rack seal. Serious cases need a rack replacement.
Tech System Failures
The Cannon-X has a big touchscreen with lots of features. It connects to your phone. It has navigation and voice commands.
But I see these screens act up constantly. They freeze mid-drive. Bluetooth won’t connect. The navigation sends you the wrong way.
One customer couldn’t get wireless charging to work. Another said voice commands never understood them.
Warning Signs
Tech problems show up as:
- Frozen screen that won’t respond to touch
- Phone won’t pair or keeps disconnecting
- Apps crash or won’t open
- Wireless charging pad doesn’t work
- System runs very slow
How to Check It
Here’s my troubleshooting process:
First, check if software updates are available. The dealer can install these.
Try a system reset. Hold the power button for 10 seconds. This fixes many glitches.
Inspect the screen for cracks or damage. Physical harm causes touch issues.
Make sure your phone is compatible. Check GWM’s approved device list.
My Fix: Usually a software update solves it. Severe cases might need a screen replacement.
Comfort and Vibration Issues
Several owners complain about excessive shaking. They feel vibrations through the floor and seat. Long drives become uncomfortable.
The ride feels rougher than expected. Bumpy roads make it worse.
In my opinion, some of this is normal for a truck. But extreme vibration points to real problems.
Warning Signs
Look out for:
- Strong vibrations at idle or while driving
- Uncomfortable bouncing on rough roads
- Shaking that gets worse at certain speeds
- Rattling sounds from underneath
- Poor handling or wandering
How to Check It
When diagnosing ride comfort, I do this:
Check if wheels are balanced. Unbalanced tires cause vibration.
Test the suspension components. Worn shocks make everything feel rough.
Drive the truck on different road types. This shows if it’s a suspension or tire issue.
Verify the engine mounts aren’t broken. Bad mounts send vibrations through the cabin.
My Fix: Balance the tires and check tire pressure. Replace worn suspension parts if needed.
Poor Fuel Economy
Many Cannon-X owners tell me they’re shocked by fuel costs. The truck uses more diesel than advertised.
From what I’ve seen, several things cause this. Driving style matters most. Lots of idling and quick acceleration waste fuel.
Overloading the bed makes it worse. So does towing heavy trailers constantly.
Skipped maintenance plays a role too. Dirty air filters and bad injectors kill efficiency.
Warning Signs
You might have fuel economy problems if:
- You’re filling up more often than before
- The check engine light is on
- Fuel smells bad or contaminated
- Air filter looks black and clogged
- Engine performance has dropped
How to Check It
Here’s my fuel economy diagnosis:
Check tire pressure first. Low tires increase rolling resistance.
Inspect the air filter. A dirty filter chokes the engine.
Scan for engine codes. Injector problems show up here.
Review how you drive. Aggressive habits double fuel use.
Look at the fuel itself. Poor quality diesel causes problems.
My Fix: Replace the air filter and drive smoother. Use quality fuel from major stations.
Recall Information
As of now, no major recalls exist for the Cannon-X. GWM hasn’t announced widespread defects.
But staying informed matters. Recalls get issued when problems affect many trucks.
Check the official GWM website regularly. Your local dealer can also search by VIN number.
If a recall happens, the fix is usually free. Don’t ignore recall notices.
Final Thoughts
The GWM Cannon-X delivers good value for the price. It competes well with trucks like the Triton and Ranger.
But it’s not perfect. The problems I’ve covered are real. I see them in my shop regularly.
Knowing these issues helps you make smart choices. If you own one, watch for warning signs. Catch problems early before they get expensive.
If you’re buying used, get a pre-purchase inspection. Have a qualified mechanic check for these common faults.
Remember, every truck is different. Your experience might vary. Some owners never face these issues.
Regular maintenance prevents most problems. Follow the service schedule. Use quality parts and fluids.
FAQ – Common Questions
What fails most often on the GWM Cannon-X?
The diesel particulate filter causes the most headaches. Steering system issues come second. Tech glitches are common too. Engine vibrations bother some drivers. Fuel consumption higher than expected rounds out the top five.
The screen on my Cannon-X won’t respond. What should I try?
Start with a simple restart. Hold the power button down for 10 seconds. Check if updates are available at the dealer. Make sure nothing is blocking the screen. Verify your phone matches the compatibility list. If nothing works, the screen might need replacement.
Why is my DPF warning light flashing?
This light means your diesel filter has problems. It’s probably clogged with soot. Short trips don’t let it clean itself. Highway driving helps burn off buildup. If the light stays on, bring it to a shop. We can force a cleaning cycle or replace the filter.
Where can I find a good mechanic for my Cannon-X?
Look for an authorized GWM dealer first. They know these trucks best. They have the right tools and training. They use genuine parts too.
Independent shops work if they specialize in Chinese vehicles. Check online reviews carefully. Ask if they have experience with GWM models specifically.
