The pre-sale price is 5,000 less, but adding the four-wheel drive and the advanced package pushes it back up to 360,000. 🤨

I've had my car for four and a half years and it's only done 36,000 km. It's a 2019 model with the 4J11 engine. Recently, when I start it cold, the engine struggles a lot. The RPM doesn't go up immediately, and the needle wobbles between 500 and 1000 for a few seconds, making it feel like it's about to stall. Then the RPM suddenly jumps to 2000-3000 before settling back to normal idle after a few seconds. There are no warning lights, and once it's running, everything seems normal. I've cleaned the carbon buildup and throttle, and checked the intake for leaks, but the issue persists. I'm not sure what to check next. What should I look into?

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?
