2006 infiniti g35 rattling noise Videos

I had a Infiniti I35, It started off like with symptoms like running a little rough. I thought I had a clogged filter or bad gas. It then got worse over a few weeks til finally it was unbearable and the car did not want to run over 35-40 mph or 2000 rpm without making a rattling noise in the engine that sounded like a bunch of aluminum cans being thrown around. I took it to my local mechanic and he looked for the error code. It only showed one, which did not really suit the problem, but following what we thought was common sense problem solving, we changed the spark plugs, inspected the injectors, checked for a clogged converter and . We had a few things we put on the idea block, but did not do and that was change the fuel pump and replace any sensors that might be bad. Additionally I have always used PREMIUM fuel only. Nothing seemed to work. Finally, he advised me to take it to the Infiniti dealer which I did. They checked it out and said my problem was the transmission was going bad and causing the cascade of problems. I knew that I had noticed a jerking shift over the last 8 months in my transmission so the idea did not seem totally far-fetched. I paid the dealer the $125 for the diagnostic and took the car back to my local mechanic and orderd a used transmission (for around $700) I am now waiting on it to arrive and get put in the car. I pray it works. I would rather fix my car than have a car payment....

it is normal, I know it sounds bad but it is the flywheel. When we got our z it had that nocie and took it to a z specialty shop and they said it is normal and we changed the flywheel out to a light weight flywheel and it is even louder, but normal. In parking lots of just sitting people think there is something wrong but it is normal.

I have a 06 350z roadster and sometimes it sounds like if i were driving a truck

It might be the TIMING CHAIN TENSIONER. Yet, mine is making the same noise and I have my mechanic replaced it. Still doing, Mine only does it in cold start. If yours does it in warm starts you might to get it checked by a specialist. Good luck!
