Is the Genesis GV70 engine idle vibration very noticeable? I saw a short video where a bottle of mineral water was placed on the engine, and it moved to the edge and fell over.

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!

I saw a video on TikTok about the Genesis 4S, saying the new model will switch to a 2.5T engine. Why haven't I seen the 2.5T?

After turning off the engine and locking the car, the driver's side window automatically rolls down. While driving, the driver's window button is sometimes responsive and sometimes not. Whether raising or lowering, once the button is pressed, the window moves directly to the bottom and won't stop in the middle. After reaching the end, you can still hear a clicking sound inside the door panel. Is the window button broken? Could you provide a replacement tutorial, preferably with a video?

When driving the Tiida, there's always a rolling sound like a water bottle moving back and forth, but there aren't any bottles with liquid inside the car. What could be causing this?

Choosing between the G80 and the XFL depends on your personal preferences and needs. Here are some things to consider: 1. **Brand and Model**: - G80 generally refers to the Genesis G80, a luxury sedan known for its comfort and advanced technology. - XFL typically refers to the Jaguar XFL, which is the long-wheelbase version of the Jaguar XF, offering more rear-seat space and luxury features. 2. **Performance**: - Consider the engine options and horsepower each model offers. The G80 might offer a more powerful engine, while the XFL might focus on a balanced ride. 3. **Features**: - Look at the features each car offers, like the infotainment system, loudspeakers, safety features, and interior quality. The G80 is known for its tech-savvy features, while the XFL may emphasize luxury and style. 4. **Fuel Economy**: - Check the fuel economy for both. If fuel efficiency is a priority, this might influence your decision. 5. **Comfort and Space**: - If rear-seat space is important, the XFL might have the edge due to its extended wheelbase. 6. **Budget**: - Consider the price and what fits better within your budget, including maintenance costs. Ultimately, test driving both and considering these factors could help make your decision easier.
