[logicmobile]

hey guys does ever happen to you that when your driving and suddenly jerks ? its not the road cause you can feel it that there is something wrong and it happen a lot of times now like 3-4 times a day....pls help

I've got about 600 miles on mine and nothing like that yet. I find the throttle pretty touchy but I'm getting use to it. Just can't wait to really jump on it after I get past the break in period. Does it jerk foward? I'll keep my eye on this.

i'm guessin you have an automatic... sounds like you need a valve body. common problem

[logicmobile]

wow you knew what i have , and yes i do have automatic and what do you mean by vavle body??? and you said its common problem?? and it does jerks forward

[infinititech1]

does it do it at about 30-40 mph?

valve body is in the transmission...

[logicmobile]

you are darn right on that ,well actually 30-45mph

im actually going to infiniti dealership tommorow "5-10-07" and im gonna tell them that, but how do you know that is the problem and how would they know if thats actually the problem , is there any device that use to see which one is the problem,... well hope so , anyway thank you for all responses i appreciate it...

[infinititech1]

lol...fixed the same problem many times. its a pretty common problem. valve body should fix your problem

[logicmobile]

guess what they dont believe me , he actually said that " this forum is just a bunch of kids making up some stuff and they are not actually infiniti technicians...." anyway how much is the stock valve body anyway?

[dunnojack]

OP, do you have an 07 g35?

infinititech...........since you say this is a common problem, are infiniti transmissions prone to failure?

how often does a car need a new valve body? will one replacement last another 70000 miles?

[logicmobile]

no sir , i have 03 sedan g35

[infinititech1]

it doesn't happen to all of them. and i wouldn't have gone in there and told them that you heard "this and that" on a forum. i would have said my friend is an infiniti tech and told me this is a common problem.

[logicmobile]

im sorry to say that i dont mean to used this forum to say it to them i used this forum is because people here are have more knowledge on cars than them is because that we all share information, and sorry again, anyway all i mean to say is they dont pay attention to the customers complaint, well i guess in my side that ill wait for the time that i can assure that the problem i have on my car is enough to see to be fix...
