When the 2006 Legacy is in drive and you press the brake, there's a "doo doo" noise from the chassis, and the steering wheel and brake pedal vibrate. Sometimes it's mild, sometimes strong, and sometimes there's no issue at all. Could it be because the brake silencer pads weren't installed properly?

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!

Maintenance guide for the 2007 Opel Astra: 1. **Regular Oil Changes**: Ensure you change the engine oil and oil filter every 5,000 to 7,500 miles to keep the engine running smoothly. 2. **Brake System Check**: Inspect brake pads and discs regularly, approximately every 10,000 miles, and replace them as needed to ensure safety. 3. **Tire Maintenance**: Check tire pressure monthly and rotate tires every 6,000 to 8,000 miles to ensure even wear and prolong tire life. 4. **Air Filter Replacement**: Replace the air filter every 15,000 to 30,000 miles to maintain optimal engine performance. 5. **Coolant Level**: Check and top off the coolant level regularly to prevent the engine from overheating. 6. **Battery Check**: Ensure the battery terminals are clean and the battery is functioning properly, especially before winter. 7. **Transmission Fluid**: Inspect and, if necessary, replace the transmission fluid every 30,000 to 60,000 miles to ensure smooth gear shifts. 8. **Spark Plugs**: Replace spark plugs every 30,000 miles to maintain fuel efficiency and engine performance. 9. **Suspension and Steering**: Regularly inspect the suspension and steering components to ensure a comfortable and safe ride. By adhering to this maintenance schedule, you can help ensure your 2007 Opel Astra continues to perform reliably.

Hey everyone, when you auto park your new GA8 and then start it again, do you hear a creaking sound? I haven't noticed that with other cars. Also, sometimes when braking automatically and the speed is close to 0, I feel the brake pedal jitter downward with a continuous noise. It's happened twice in 7000 kilometers. It doesn't affect the use, but I'm curious. Could this be a sign of a potential future issue?

Has any owner of the 2020 BYD Song PLUS gasoline version encountered this issue? When driving at a speed of 90-110 km/h and applying the brakes, the steering wheel shakes, and both the engine compartment and brake pedal vibrate. What could be the problem?

I have a 2017 V60, and sometimes I hear a clicking noise from the chassis when driving at high speeds. The noise disappears if I lightly tap the brakes. I suspect it might be an issue with the brake system, but I've been to the dealership twice and they couldn't solve it. Has anyone experienced a similar problem? Any solutions would be greatly appreciated!

Hi everyone, when I drive fast and press the brakes a bit hard, there's a thudding sound and the brake pedal feels like it's bouncing. This doesn't happen when I'm driving slowly or pressing the brakes lightly. Is this the ABS system kicking in or is it an issue with the brake pads? Also, regarding the temperature gauge on the dashboard, I remember it used to show two bars as soon as I started the car, right in the middle, but now it takes a few minutes to gradually rise half a bar at a time. Am I remembering wrong or is the coolant level low?

If I add a turbo to a 2.5 Forester, can the transmission handle it? Or should I go for a stage 2 tune? The brake pads definitely need to be replaced, but I'm worried the transmission might not handle it, even though Subaru's transmissions are quite strong.

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!

I've got a 2022 GTS with over 10,000 km on it, and I've noticed an issue. When I turn the steering wheel all the way while moving forward or reversing, there's sometimes a loud noise from the chassis. It sounds like something is stuck or like a brake squeal. Has anyone else experienced this?
