During the rainy season, typically from April to August, the car doors cannot be opened from inside or outside, while they function normally at other times. Could it be that the lock mechanism is affected by moisture on rainy days? What might be the issue here? Experts, please help! Thank you!

During the rainy season, my car has been parked outside for the past few days. After starting the car and pressing the brakes, I hear water sounds from the chassis. I've checked the sunroof and there's no leak, also tested the floor, and it's fine. Could it be that the frame has taken in water? Can any expert analyze this?

I have a 2011 Smart W451, and there's a buzzing noise after starting the engine. Here's what's happening: when I start the engine, everything is normal for the first 2 seconds, but after that, a low-frequency buzzing sound begins. The noise seems to come from the rear of the engine, near the inside of the passenger side. There are no fault codes, and everything else like acceleration and speed is smooth with no issues. I recently changed the fuel pump and haven't finished a full tank yet. The noise inside the car seems to be coming from below the passenger seat but slightly forward. I've changed the engine mounts, and the alternator belt looks fine. Has anyone experienced the same issue? Any help would be appreciated.

I have a 2019 model car and after I activated and then deactivated the child lock on the rear right door, it can't be opened from the inside anymore, only from the outside. Has anyone experienced this? How did you solve it?

I'd like to ask fellow car enthusiasts a question. For the 2020 4WD Elite Edition Jeep Compass, is there a button inside the car to open the trunk? I've been opening it from the outside directly for four years. Does anyone know?

When you open the fuel cap of your 2014 ASX and hear a sound of air being sucked in, it could be due to the pressure difference between the inside of the fuel tank and the outside air. This is usually normal and can happen because the fuel system is sealed to prevent fuel vapors from escaping. If the sound is frequent or you're experiencing other issues, it might be a good idea to have it checked by a professional.

For your first time driving a 09 Mazda 6, here are some things you might want to consider: 1. **Basic Checks:** Before you start driving, check the fuel level, tire pressure, and ensure all the lights are functioning properly. 2. **Maintenance History:** If possible, review the car’s maintenance history to ensure it's up to date with regular services. 3. **Test Drive:** Take the car for a short drive to see if there are any unusual noises or vibrations. 4. **Visit a Mechanic:** If you're unsure about the car's condition, it might be a good idea to visit a mechanic for a thorough check-up. 5. **Familiarize Yourself:** Get comfortable with the car's controls, like the brakes, accelerator, and steering. Remember, safety first!

Do you have issues with window noise? When the car is parked outdoors, during rainy or very hot days, after starting, there's a creaking sound from the rooftop or windows, which disappears after driving for a while. I should mention that if it's parked in an underground garage, there's no noise. Even after reopening and closing the sunroof, the problem persists. When the noise occurs, it gets louder if the road is uneven. The model is a six-seater.
