annoying pretensioner rattle noise

[stevenli0716]

It's been a while already. I dont know when it begins. Do you guys have any solution to fix this?

May need to tune up a little or wear a headphone, the noise beside the knocking is the point. When I go over a damp or curb or uneven road, there will be rattle squeaky sound like this, it's very annoying.

No, but it does seem like you will need to replace the seat belt pretensioner unit.

The unit cost $186.92 online on this website.

Depends. Warranty or no warranty?

Warranty: Let the dealership repair it.

No warranty: DIY or a service shop.

A good reputable shop mechanic can easily swap out a bolt-on part as good a dealer service tech.

I personally would just do it myself if it happens out of warranty in my car.

Note: I would try to tighten the bolts on the seat belt tensioner first before swapping it out. A bolt may loose and is causing it to rattle.

Thank you, I had try to use my hand to find out which part is loosen. I don't seen any. I think I will just bring to my friend works in the service shop to take a look on it.

You are welcome.

It is possible that the rattle noise is from an internal issue within the pretensioner mechanism itself. Hopefully your friend can sort it out for you.
