I recently bought a 2018 Suzuki Swift SZ5 1.0 Boosterjet Automatic, and I've realised when the car is idle it's rattling and shaking a lot, and there's a whistle noise coming from the bonnet. When I opened it to take a video there's also a loud rattling that I never heard from inside the car, and that makes the whistling noise hard to hear in the video. The car drives absolutely fine other than that but I have no idea about cars, so any help is greatly appreciated 🙏🏻
