So almost two months ago I bought my first Z. A 2004 coupe with 56k miles on it. Car ran great when I got it. Put a borla exhaust on it and about a week later I started hearing a clunking noise only when accelerating. It being under warranty I took it into the dealer. They have hadj car over 6 weeks and have gone through 3 trannys, a new clutch, flywheel, and driveshaft and can't figure out what's wrong with the car. This is a pretty loud clunk only coming when accelerate which isn't a normal Z noise such as the throw out bearing. Any thoughts or suggestions?! They've said from day one the engine runs really strong and that it's not the engine. Well after replacing everything else they tell me today they might replace it as it's the only thing left.

 

If its at all possible I would take it somewhere else.

 

I would be looking at that exhaust being that the noise only started after that was installed. The pipes could just be bumping up against something.

 

how can any competent shop/dealer not figure this out.....

dealerships don't fix it, they replace it.....

I mean that dealer has a good rep in my area compared to the other Nissan dealers down here in new Orleans. Plus they are already familiar with my car and the problem as well as replacing many parts under warranty. Its not the exhaust bumping around.

 

Lemon law.

 

any recording of the noise?

 

Ya lemon that **** before you lose your warranty

 

Exactly where is the noise coming from?

 

Have them swap the engine for a new one and take it somewhere else. At least you got a brand new car internally out of it.

 

Rear diff mount?? Mine clunks when I shift hard too. The bushing has been blown out on mine for years.

 

i was thinking the diff too. buy solid ones and see if thats the case. worse case you spent 200 and got solid mounts.

 

drive over here to biloxi and let me take a look at it. the smart thing to do would be jack up the rear and let someone hit the gas with it in gear and see what they get. something like that sounds like a broke tranny mount or a broke engine mount. i would even check to make sure the differential bolts are tightend.

 

Good afternoon sir,
