The Jietu 90 has too many issues. At less than 20,000 kilometers, the one-touch start fails to work, and the 360 camera malfunctions, sometimes even resulting in a black screen.

The check engine light is on for your 2010 Mazda3 hatchback, and the fault code indicates that the fuel trim system is too lean after the catalytic converter. Here's what you can do: 1. **Check for Vacuum Leaks**: Inspect hoses and connections for any leaks that might be causing the issue. 2. **Inspect the Oxygen Sensors**: A faulty oxygen sensor can lead to incorrect fuel mixture readings and should be checked. 3. **Examine the MAF Sensor**: The Mass Air Flow sensor might be dirty or malfunctioning, affecting the air-fuel ratio. 4. **Look at the Fuel System**: Check the fuel injectors and fuel pressure to ensure they are functioning properly. 5. **Check the Catalytic Converter**: Although less common, a failing catalytic converter can cause similar issues. 6. **Professional Diagnosis**: If you're unable to identify the problem, it may be best to consult a professional mechanic for a thorough diagnosis. Remember, addressing the issue promptly can prevent further engine damage.

Why is the clutch master cylinder of my Haval leaking oil after running less than 20,000 kilometers?

I'm driving a 2021 1.4T Comfort T-Cross, and it's run less than 20,000 miles. There have been two instances where it suddenly braked and paused while driving normally. What's the reason for this? Does anyone know?

Just got the car 2 days ago. When I picked it up, it showed 435, but it seems like I've only driven less than 300, with a bit over 90 left, so I went to charge it. Is this normal for city driving?

Can version 3.1.9 be upgraded? It seems that versions 3.0.3 and 3.1.2 were pulled back just a few days after their release. Version 3.1.10 was just released a couple of days ago and hasn't been pushed out yet. Currently, version 3.1.9 is being pushed in China. In the U.S., 3.1.9 was pushed out in early July, and it has been available in Europe for about a week. According to U.S. car enthusiasts on forums, some vehicles experienced a flickering issue with the 360-degree surround view in versions 3.0.3 and 3.1.2, where the screen would briefly go black and then light up again. After upgrading to 3.1.9, the issue was significantly alleviated during the first week, with flickering still occurring but only going black for 0.2 seconds and then automatically recovering, not affecting usability. However, the results after one week were not satisfactory, with the 360-degree surround view showing more frequent "camera unavailable" warnings than before, still severely affecting use. Yet, some car owners reported never encountering this issue (even with the problematic 3.x versions), so it might be related to a specific batch of parts or the vehicle's personalized settings. Have car owners in China noticed this issue after upgrading, or are there any other problems?

I'm sincerely looking to buy a used Taycan, 2021 model with less than 40,000 km. Preferably in white. Both Shanghai plates and non-local plates are fine. Ideally, the interior should have red and black, with Bose loudspeakers, electric sound system, and display screens. Budget is 500,000 RMB.

I have a 2020 Touareg 3.0, and recently I've noticed that the 360-degree camera is getting less clear. Does anyone else experience this?

When I suddenly shift to reverse gear, the 360 camera doesn't display. The screen isn't even black; it shows nothing at all. Do you have any idea what could be happening?
