Hey fellow 2025 GWM GS8 owners, have y'all experienced issues like the system freezing, screen flickering, rebooting, or crashing? I'm planning to buy one, but the online cases are kinda worrying.

I own a 2014 SsangYong Korando, 2WD high trim, 2.0 gasoline. Recently, the check engine light occasionally turns on with the error code indicating a misfire in cylinder 1. Sometimes it turns off by itself. I've swapped spark plugs between cylinder 1 and 2, ignition coils between cylinder 1 and 3, and even swapped the injectors. I planned to use elimination to check if it's the injector issue, but after each swap, the misfire code for cylinder 1 still comes back eventually! The engine idles with slight vibrations, but I don't feel any power loss on the highway—it easily goes over 160 km/h. Later, I measured the cylinder pressure: cylinder 1 is at 8 kg, while the others are over 10 kg. After researching online, I suspect it's an exhaust valve issue. Now I'm really torn. Should I just let it be, or go for a major repair? I read online that some people can fix it by opening the cylinder head without removing the engine. But the local big auto shop is no more, and the private mechanic suggests removing the engine, which I really don't want to do—worried it won't fit back as perfectly as the original. It's stressful because I bought this as a first car for my father, who has loved cars all his life, and now this happens. I've been to various places without a clear diagnosis. Some say it's slight cylinder wear, some say valve leakage, and others mention cylinder head design flaws. Any advice from fellow Korando owners on how to solve similar issues would be greatly appreciated!

Hey fellow car owners, does the 07 Lexus IS 250 (low trim without screen) have a BLIS system? Also, is there a USB port, and where's the cigarette lighter located?

Will upgrading the system fix the freezing of the central control screen in the 2023 X90 Zilong Changsheng 7-seater?

Hey fellow car enthusiasts, my car is over seven years old and I haven't changed the tires yet. It's only been driven 60,000 kilometers. The tires are slightly aging, but I haven't driven much in recent years. It's mostly parked in the basement, so it's rarely exposed to the sun. Should I change the tires? I'm planning a long trip and am a bit worried!
