When I start the car and begin to accelerate, the engine (maybe) has a loud rattle noise like it is "trying" to work. Once it gets to third gear, the noise goes away. This only happens on a cold start, not when I am stopped at a traffic light or such. I have had it to two different Acura dealerships and have had $3K repairs done but the noise is still there. If I take it to other shops, nothing comes up on the diagnostic test. It sounds horrible and is embarrassing. This started at around 69K miles. PLEASE HELP! I do not want to be screwed out of more $$$ by Acura!

Question: Loud rattle noise from engine on cold start

Has the engine had frequent engine oil and filter changes and what is the mileage is on the car now? When this noise occurs does the oil light stay on or go off. My first fear would be bad connecting rod bearings.It's hard to comment on a noise without being able to hear the noise first hand. When you have had the previous work done did yo point out the noise to the person working on the car and what did they say when the noise reoccurred?

I have always followed the recommended oil changes with synthetic oil. The car currently has 91K miles. The oil light does not come on. The noise is very obvious and the technician can hear it. The noise has been intermittent. Weeks can go by and I won't hear the noise but, like this week, the noise is back and very loud. I have brought it to independent shops who tell me they cannot diagnose the problem if there is not a diagnostic code on the car computer and recommend I take it to a transmission shop or back to the dealer.
