Modifying the steering wheel does not violate relevant regulations, and the annual inspection focuses more on the performance and appearance of the vehicle. As long as the owner ensures the modification is done at a compliant 4S shop, it can fully pass the annual inspection. Installing a multi-function steering wheel: The advantage of a multi-function steering wheel is that the driver can operate various vehicle devices via buttons on the steering wheel, eliminating the need to search for buttons on the central console. This allows the driver to focus more on the road ahead, significantly improving driving safety. Installation is possible: Therefore, as long as the modification is done at a compliant 4S shop, a multi-function steering wheel can be installed.

Regarding the inspection of a modified multifunction steering wheel, I know that vehicle inspections prioritize safety and factory consistency, especially for critical components like the steering wheel. If the modification alters the airbag position, steering system, or steering wheel shape, it may be deemed an illegal modification. Standards vary by local vehicle management offices, but most regions strictly enforce changes to safety-related parts. For example, if button relocation affects airbag deployment, the inspection will fail, and in severe cases, you may need to spend money to restore the original setup. It’s advisable to check local regulations before modifying and consult professional institutions to assess risks—safety comes first.

I've done this kind of modification before. I added multifunction buttons for better handling comfort, but during the annual inspection, it was pointed out that it affected the original vehicle's safety design. The inspector explained that the steering wheel and airbag are integrated, and arbitrary modifications could cause data errors, triggering system alarms and failing the inspection. Later, I had to ask a friend to help remove it and restore the original setup to resolve the issue. So based on my personal experience, simple cosmetic modifications might be okay, but altering too much in terms of functionality or structure carries high risks. It's better to save that money for actual car repairs.

For car enthusiasts, modifying the steering wheel is indeed trendy, but you need to be cautious as it's tied to annual inspections. Think about it—during inspections, they focus on the airbag and steering column linkage. If your aftermarket accessories block the sensors, causing the system to malfunction, you'll fail the inspection outright. At best, you'll face costly rectifications; at worst, you'll be fined. My advice is to stick to minor adjustments, like changing the leather cover without altering core components, to avoid future hassles.
