Everytime I start my 03TLS, I hear a bang coming from the engine bay and feel it on the pedal. A little hard to explain, but if anyone can relate let me know. Thanks

 

Doesnt sound good, you should take it in for service.

 

the only bang i can think of, is when the AC makes a noise, turning on and off. its pretty long sometimes.

 

I've read that the hydraulic engine mounts make this noise at start up. Mine has done it on occasion from day one. I haven't worried about it.

 

ahh... that would make sense .. mine has been doing that intermittently for the past 8 months!

thanks for the info

 

Well thats more like a thump than a BANG But yeah my car does that sometimes as well. Seems to be related to the AC but maybe its the engine mounts as stated before.

 

I have the same problem in my 01. It sounds like a thump when you start it, I think I feel it more on a cold start.

 

Probably the engine mounts. My car has done it every now and then since I bought it, although I haven't heard it in a while.

I had a friend with a mid '80s Civic (280,000 miles on that bad boy!) that made the same exact sound every time you started it, since his mounts were so worn out.

The question has been asked before in the link above. According to Jens, Acura gives credit to the engine mounts as was mentioned by cl-tl.

I've got the same noise and it has not caused any problems to date.

 

That makes me feel better. . . It happens pretty much every morning and has been since day one. . .

 

Also, try shutting the A/C completely off before shutting the car off. Then restart it and see if it still makes the bang. Mine does this too when my A/C is on and I traced it to the compressor starting up. It's probably a combination of the load of the compressor on the engine and its effects on the engine mounts. It won't do it if the climate control is off.

 

My 02 tl-s also has this issue. I get that THUMP only when I start the car. But like everyone said above, it does not occur every time.

 

That bang or pop sound when u first start the car is from back fire back in to the air box.

 

If I was getting a backfire into my airbox I would be having it looked at like yesterday. When I first got my car I noticed the same pop, and after doing some research, I concluded it was indeed the motor mounts. Nothing to worry about according to Acura.

Im a acura mechanic, i notice the noise on my 2000 tl i metion it to the tech line they told me is a little back fire, when u guys get a chance disconnect the air box tube and start up the car u hear it.

 

I have the same "bang" at startup on my 2003 TL-S. I brought it to the acura dealer and showed them and they told me it was the hydralic motor mounts. He then brought me to a car they have on the lot and it did the same thing. My worry went away. No big deal, but I can't blame you for your concern!

 

My 01 never did this and my 03 did not do it until today after I read this post. Thanks guys

 

so does this mean when i start up my car today im going to get this bang also, ive never noticed it before but im going to be looking for it now. Great.

 

Yeah, and also look for your windshield to randomly blow off at highway speeds and all four wheels to bend in heavy cornering..
