I'm still in my break-in period, only 400km. When I press the gas pedal, I get very slow response. The engine seems to make a loud sound and the car doesn't accelerate as much. Anyone experiencing this?

 

If you think it sounds abnormal, take it to your dealer. Sooner, rather than later. If something's really wrong, then it can only get worse, and sometimes rather quickly.

If nothing's wrong, at least you'll get a free car wash. [img]/w3timages/icons/smile.gif[/img]

I didn't really give mine a break in period, it wanted to get up and go right from the start.

 

That's interesting. I'm an Acura 3.2TL-S driver and a friend at work got a loaner G35 from the Infiniti dealer while his j30 was being worked on. I asked him how he liked it and he said that it seemed sluggish to him. I was surprised because I was amazed at the G35's power when I test drove one a couple months ago. So I asked him if I could try it out and we went for a spin around the block. Indeed, he was correct. The car was slow to react to the gas pedal being depressed, even at 3/4 of the way down. It sounds similar to your problem, except that the engine didn't really get loud, it just didn't seem to be getting gas quickly enough. In any case, it sounds like there is a problem and you should take it to the dealer as soon as possible. Good luck.

 

the thing is, you cars computer gets to know your driving style, and it programs its self and picks it up. That does sound very abnormal that you're not getting good pickup. Just take it into the dealer and have them check it out,its worth it, wow, you just paid them over 30 grand

hmm. Ive never had this slow pick up problem.. I once read some early model 2003's had some kind of problem like this but some timing advance was done by the dealer (I remember I read this somwhere a long time ago)


Reguardless.. I would take it to the dealer to check it out..

 

Try disconnecting the battery overnight and see if that helps.

 

mine has ~3000 mile, I'm having this question from day one as I had posted a couple time before about it. if I drive around 40 mph at 2000 rpm the engine sounds very loud without feeling the push.
Accelaration from standing is another example, I don't feel the push until 3rd gear is engaged (mine is AT), the engine roars loud on 1st and 2nd at ~4500 rpm without generating much torgue, Good thing is AT switches to 3rd very quickly from 2nd. I don't know how I can beat other sport sedan without a good jump with this car.

I don't seem to have that issue, my "G" accelerates fine. The only 2 things I can think of that may cause that 'roar' are;

1- The fan clutch is still engaged and the sound is the air the fan is trying to move. This will decrease your hp slightly.

2- The tranny torque converter is not right and all it is doing is slipping more than engaging, just spinning instead of locking up.

Either way, I would take it to the dealer and have them check it out. Keep us posted, just hope the autos are not having trouble like the manuals.

 

As some of the guys have said, the computer learns your driving style quickly, and during breakin it's easy to granny too much causing the computer to learn some bad habits.
As Merlin said, it's a matter of disconnecting the battery for 12 hrs. to unlearn all the 'habits' .
Seems like a long time to disconnect, but that's the word from the peeps at my dealership. All you'll lose are your radio presets, your distance travelled on the resettable odometer, and if you have navi, you'll lose the average mpg's accumulated to date. I've done this a few times and it's no biggie to do and seems to work well.
If you do it, be sure to disconnect the neg. terminal at the batt. so as not to chance any arcing. G/L [img]/w3timages/icons/smile.gif[/img]

Merlin, I broke-in my car in a far more conservative way than my normal driving habits now. My car does have great acceleration.
However, from what I understand from various comments, if I disconnect the battery overnight, the car will re-learn my current driving habits and have greater acceleration. Is this correct? Thanks, Ken

 

From some of the info, it takes about 12 hrs. The car will otherwise slowly learn your driving habits without a disconnect, but it's gradual and the difference isn't as dramatic.

1Ken,
That is pretty much the experience we have had here. Try it "Mikey" you may like it.[img]/w3timages/icons/smile.gif[/img]

 

Never had an acceleration problem but since I did do a slower break-in, I took your advice and disconnected the battery for 12 hours last night. Didn't notice greater acceleration but was very happy to notice that the car downshifted more quickly into lower gears. I felt the downshift was a bit slow before but this corrected the problem.

I had the exact feeling of sluggish accelerationwith my sedan-especially after driving an identical loaner that felt much quicker. The dealer performed a compurter reset (apparantly the same effect as disconnecting battery for 12 hours, but can be done instantly by a dealer tech) and the car felt much better after-no small improvement, a real change so that the car responded to throttle input much better.

After about 3 months, I am still happy with it, so it muct have learned my lead-footed ways.

I would highly recommend all G owners to do a computer reset, then drive you desired style and note the difference.

Look at it like the possibility of adding extra power for $0. And if you see no difference- hey , you didn't pay anything!
