Rattling in Engine Bay - High Pressure Fuel Pump -
So my 2015 TLX Tech (2.4L) has been making this rattling sound from the engine bay. Finally took it to my dealer to take a look at it and turns out the "high pressure fuel pump" needs to be replaced. They ordered the parts and it should repaired tomorrow. The Service Tech said it was a common problem and knew right away what the issues was when I mentioned it.

Maybe this is different, but for my car, 16' 4cyl, I got both chirping and rattling noises in the engine bay. They replaced that high pressure pump, which fixed the chirping noises. Sad part is the damn noise came back after a month. I have not taken back to the dealership yet. As far as the rattling noise, you might want to have them look at the tranny mount. I got that replaced, and the rattling is gone.

Yup, I did saw that when I first notice my car starting to chirp during idle. I did had a hard time getting them to agreed and get it fix since that TSB is for v6 model and mine is a 4 cyl. I had to record a few videos clips and had that sent to the manager. As far as the rattle noise OP mentioned, I had a similar situation where they "can't" hear it or duplicate it. They replaced front shocks and front engine mount. They said they found those parts are bad, but that does not fix the rattle noise I had, plus when I hit the gas, I can hear a clunk. Finally they replaced the tranny mount, which took care of the rattle and the clunk noise.
OP, you said the car has rattle noise and they said it the fuel pump. Mine is cause by chirping, cricket like sound. The rattle noise is cause by bad tranny mount. So I want to give my experience of mine and see if they can check out those issues as well when you at the dealership.

Glad that fixed for you OP. Luckily your tech did hear the rattling and clunk sound and got that fixed asap. I took a drive with 3 different techs and they all said none until they gave up with me and decided to replaced the tranny mount, and that only took me about 8 visits in 1 year.
I think, sadly, the clunking will likely come back. My engine has a very low idle rpm, which causes the engine to vibrate. I asked numerous times if they can adjust the idle, and they all said NO. Hopefully I'm wrong, but this in long term will cause wear and tear on those mounts and I'll be back to square one again.
