Thinking about getting a GWM Tank 300? This affordable off-roader has caught many eyes with its rugged looks and competitive price point. But beneath the attractive exterior lurk some serious issues you should be aware of before signing on the dotted line. Let’s dive into the most critical problems owners and experts have identified.
Dangerous Braking Issues That Could Put You at Risk
The most alarming problem with the GWM Tank 300 involves its emergency braking behavior. During hard stops from highway speeds, both rear wheels actually lift completely off the ground – creating a potentially life-threatening situation.
Testing has revealed that during 100 km/h emergency stops, the rear wheels leave the ground for about 0.12 seconds. During this time, the vehicle travels 2.66 meters with:
- No rear-wheel braking assistance
- Zero directional stability
- Reduced overall stopping power
This happens because of extremely soft front suspension that causes excessive nose-diving. Automotive expert John Cadogan didn’t mince words when he called this “truly appalling automotive engineering” and a “complete safety liability.”
While GWM has made some improvements to the diesel model, the fundamental braking safety issue persists across the range.
Engine Performance Falls Short
The Tank 300’s standard 2.0-liter turbocharged petrol engine struggles to move the vehicle’s hefty 2.1+ tonne weight effectively. Owners consistently report:
- Sluggish acceleration, especially when loaded with passengers
- Noticeable power loss when larger wheels are fitted
- Engine strain during towing operations
- Fuel economy that exceeds the official 9.5L/100km rating
Even more concerning is the dangerous throttle lag, where the vehicle continues accelerating for up to one second after you lift off the accelerator. This creates a hazardous situation when transitioning from acceleration to braking.
Transmission and Drivetrain Headaches
Diesel Models: Rough Ride Ahead
If you’re considering the diesel variant, prepare for a less-than-smooth experience. Owners report:
- Rough gear changes with frequent jolts
- Sluggish initial response followed by sudden power surges
- Less refined operation compared to the petrol variant
Hybrid Model: Unproven Technology
The hybrid model uses an unproven new engine (E20NA) paired with GWM’s own nine-speed dual-clutch transmission. This combination hasn’t been thoroughly tested in off-road conditions, even in the Chinese market, raising concerns about long-term reliability.
Technology Issues That Drive Owners Crazy
Infotainment System Failures
Multiple owners have experienced complete infotainment system failures where the central touchscreen becomes totally unresponsive. This is particularly problematic because many vehicle functions are only accessible through this screen, including:
- Climate control adjustments
- Driver assistance system settings
- Apple CarPlay connectivity
- Radio and media controls
When these systems fail, you’re left with limited functionality in a vehicle you’re paying good money for.
Driver Assistance Systems That Fight You
The Tank 300’s lane-keeping assistance systems are problematic and potentially dangerous. Owners report:
- Overly aggressive steering corrections
- The system’s preference for positioning the vehicle far left in lanes
- Constant fighting with the driver for control
- Random steering inputs left and right
- Intrusive driver monitoring that complains about normal head movements
While GWM has released software updates to address some issues, the fundamental problems remain.
Interior Design Flaws That Affect Daily Use
Cup Holders: A Simple Thing Done Poorly
It’s the little things that can drive you crazy. The Tank 300 features poorly designed cup holders that allow drinks to fall through, making them difficult or impossible to retrieve. Standard coffee cups sink into the holders, and you’ll struggle to get them out – a small but infuriating daily frustration.
Counterintuitive Controls
The vehicle uses a non-standard indicator design that requires pushing the stalk in the same direction twice – once to activate and again to deactivate. This counterintuitive design causes confusion and potential safety issues when you’re focusing on traffic.
Heavy Tailgate Without Power Assistance
The Tank 300’s tailgate lacks power assistance and requires considerable physical force to close properly. The design also makes accessing the boot difficult in tight parking situations – an issue if you frequently load and unload gear.
Practical Limitations for Family Use
Limited Cargo Capacity
For a vehicle marketed as an off-road adventure machine, the Tank 300’s boot space is surprisingly inadequate, especially with the rear seats up. If you’re planning family camping trips, you’ll quickly find yourself running out of room.
| Feature | Measurement | Comparable Vehicles |
|---|---|---|
| Boot Space (rear seats up) | 417 liters | Jeep Wrangler: 533 liters |
| Payload Capacity (early petrol models) | 350kg | Toyota Fortuner: 670kg |
| Payload Capacity (newer models) | 600kg+ | Ford Everest: 750kg |
Dirt and Debris Collection
The vehicle’s body-on-frame construction with visible panel gaps allows excessive dirt, dust, and debris to accumulate in hard-to-clean areas. This is particularly problematic for a vehicle designed for off-road use, where dust and mud are part of the experience.
Payload and Towing Limitations
Early petrol models suffered from an extremely low payload capacity of only 350kg, making them unsuitable for carrying passengers and gear simultaneously. While this has been improved in newer models to 600kg+, it remains a concern if you’re looking at older stock.
Long-Term Reliability Concerns
Unproven Track Record
As a relatively new model from a Chinese manufacturer, the Tank 300’s long-term reliability remains unproven. While the vehicle comes with a 7-year warranty, the effectiveness of warranty claims varies significantly by dealer.
Limited Aftermarket Support
The Tank 300 suffers from minimal aftermarket accessory availability. Major brands like ARB and Opposite Lock don’t offer suspension lifts, bull bars, or other modifications, limiting customization options for serious off-road enthusiasts who want to upgrade their vehicles.
Recalls and Service Bulletins
GWM has recalled Tank 300 Hybrid models due to incorrect jack adjusting rods that don’t meet Australian standards and cannot be used for wheel removal. While not safety-critical, this recall highlights quality control issues that might extend to other components.
The Warranty Situation
While the 7-year warranty sounds impressive, owner experiences vary widely when it comes to getting issues resolved. Some report excellent dealer service, while others describe frustrating delays and reluctance to address problems under warranty.
Should You Still Consider the Tank 300?
Despite these problems, the Tank 300 does have some redeeming qualities:
- Competitive pricing compared to established off-roaders
- Reasonable off-road capability with proper ground clearance
- Attractive styling that stands out from mainstream SUVs
However, these benefits come with significant compromises in safety, reliability, and everyday usability.
Alternatives Worth Considering
Before making your decision, consider these alternatives that might offer better long-term value:
- Toyota Fortuner: More established reliability record, better resale value
- Ford Everest: Superior on-road manners, better safety systems
- Mitsubishi Pajero Sport: Competitive pricing with proven mechanicals
- Isuzu MU-X: Excellent towing capacity and diesel engine reliability
While these alternatives might cost more initially, they could save you money (and headaches) in the long run.
The Tank 300 represents an interesting option in the off-road SUV segment, but its serious braking issues, questionable reliability, and various quality problems should give potential buyers pause. If you’re still interested, consider leasing rather than buying outright to minimize your long-term financial exposure to these potential issues.
