I've been driving my BMW 3 Series for a while, and the strange noise during startup is definitely not normal—it needs to be checked properly. Last year, my car had the same issue; I heard a creaking sound when starting, and after inspection, it turned out to be a worn-out rubber bushing in the rear suspension. The BMW 3 Series chassis design is quite sensitive, and when rubber components wear out, they tend to make noises over bumps. If you often park outdoors, exposure to wind and sun can accelerate this problem. I recommend you go to a 4S shop or repair shop as soon as possible and have them lift the chassis to inspect all suspension components, brake calipers, etc., for any looseness or corrosion. Don’t take it lightly—small issues can lead to costly repairs if ignored. When driving daily, try to start smoothly and avoid slamming the accelerator to prevent vibrations that worsen wear. The BMW handles well, but it requires timely maintenance—regular inspections and replacing worn parts can save you both hassle and money.

As a long-time car mechanic, the starting noise in a BMW 3 Series can indeed be frustrating, and it's usually related to a few areas. The most common culprits are the braking system or engine belt issues. For example, if there's dust or rust between the brake discs and calipers, friction during startup can cause noise. The BMW engine bay is compact, and a loose belt might also squeak. I must remind you not to disassemble things randomly. First, try starting the engine in neutral to see if the sound changes. If you hear a metallic clanking noise, it could be loose chassis bolts. I've seen too many cases where minor noises hide major risks. I recommend getting it checked at a professional shop and replacing parts with genuine OEM components. Remember to inspect key points during every maintenance session. BMW maintenance is all about attention to detail—don't skimp on small expenses and overlook big issues.

When I first started driving my BMW 3 Series, I also experienced strange noises during acceleration, which really worried me about safety. The sounds resembled tire friction or minor engine noises, which are usually abnormal and might be caused by unbalanced suspension or drive shafts, especially more noticeable after going over bumps. As a beginner, I immediately took it to the shop for inspection. The mechanic said it was due to aging rubber components underneath the car that needed replacement. BMW's chassis is highly sensitive to road feedback, making such noises more pronounced and potentially hazardous. I recommend you note the frequency and location of the noises, like whether they're worse during cold starts compared to when the engine's warm, as this helps with diagnosis during repairs. Regular maintenance can prevent similar issues, so don't delay in addressing them.
