Sorry I'm new to this place, but my Nissan Maxima makes a rattling noise when I accelerate between 30-58 MPH, I need help please on what the problem is.

 

Need more info. Coming engine bay, underneath, by the wheels,or?

 

It sounds like its coming from the bay. want me to record it?

 

Yes, that would help us help you.

 

The heat shields are known to rattle when they are cracked or loose, I have been meaning to have mines removed from my 04 Maxima but it only rattles occasionally so I haven't messed with it yet.

 

Could also be timing chain guides. You will hear it coming from the front of the engine.

 

Hi Guys,
Need your help here. Hopefully someone can help. I own a 2018 Nissan Maxima SV done almost 50k. I have been heering a rattling noise only in the morning from the engine bay towards the passenger side ( Most probably when the engine is cold) it comes on bumpy roads and disappears after few minutes of driving. Its not there when iddle, just on low rpms and bumps seems like a loose plastic or something, but i couldnt figure out what is it yet. ITS JUST TOO ANNOYING AND LOUD.
Took it to the dealer twice, unfortunatly couldnt reproduce the sound as it only comes in during the morning and for few minutes, and unlickily the road to my house is interlock where the sound appears.

1. I have checked and sound proofed every plastic peice in the engine bay that i have seen and believed that might make a noice. The coolant tank where it meets the body, the engine cover top left where it also has contact with the body.
2. I have checked the heat sheilds, all look solid and in place.
3. I tied up all lights wirring assuming might be hitting on something.

Please let me know if anyone had expirienced a similar problem. Thanks.
I have added a recording of the noise if that helps.
