Do your tires pick up stones and fling them onto the bodywork? Can the driver hear it while driving? I can hear it very clearly. 🤔🤔🤔

Hey everyone, can someone help me out? The loudspeaker on the driver's side of my 2011 S40 is very low. Any advice?

Model X, 40,000 km. There's a consistent humming noise from the rear wheels while driving, most noticeable at speeds of 35-40 km/h. You can feel a slight vibration in the floor when sitting in the back seat. I've been to the dealership a couple of times for this, and the last time, the technician confirmed the noise. After checking, they said the half axles are fine and concluded it's due to tire aging. I've heard that 21-inch tires tend to wear unevenly and might need replacement around 40,000 km. The tires only have 40,000 km on them, and the tread still looks clear. Is this really possible?

Is it necessary to do wheel alignment after picking up the car? I did some research and found that issues with the camber angle can lead to inner tire wear. Not sure if the new model has this problem?

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?

I'm new to cars. Last night, I didn't see clearly while turning and scraped against a pile of sand and stones. Three-quarters of the left side skirt is scratched, and there are one or two scratches on the front and rear doors [facepalm]. Any advice from the experts on how to handle this?

Today, I suddenly found that the driver's side window won't roll down, but I can hear the motor running. What could be the issue?

When it rains heavily, I can hear the sound of water on the left door of my 2017 model. I can hear it while driving, but when I shake the door, there's no sound. Does anyone know where exactly the water is accumulating?

Why does the driver's door not open with the key unlock button after locking the car from the outside, while the other three doors can be opened?

After thinking and looking for a long time, it all comes down to not having enough money. I'm planning to buy a second-hand car for around 40,000 to 50,000. I'm currently considering a Subaru Outback, but since its parts are expensive and not everyone can repair it, I'm putting this on hold. If there's an alternative, I'd love to hear it. Any recommendations? Thanks, everyone, for your advice!!! 🤔🤔🤔
