Add one more TB to the list of bad ones. I had mine do the "limp home mode" yesterday. Kinda scary since I was pulling into oncoming traffic. This is the third time ,mine has done it. I thought, like some of the oters here it was heat related, but it was only about 82 yesterday. I'll be going to the dealer on Monday, has anybody had any problems with their dealer because of an aftermarket plenum? Just curious, the service guy said it shouldn't be a problem but at 700+ for parts...shouldn't be doesn't make me feel very good.

 

Me too. However, my Throttle Body sensor problem is less server. It only causes me a "service engineer soon" light on and a not so smooth acceleration here and there. But my problem is this happened 2ice in the last 3 months. I just dropped it at the dealer this morning and he called me about 2 hours later to let me know it's the same problem as last time. I asked if there is something else that might have cause the TBS to break and he doesn't know. Anyone have any idea? btw, my car is 100% stock and I had it since 1/2005 and about 10k miles on it. thanks.

 

My car turns off by itself it has turned off twice on me so far. There might be a recall on the transmision, thats what my service guy from infiniti thinks.

 

This was my problem too - bad throttle body sensor. Fixed under warranty.

 

Same issue here as well. I have about 6800 miles on my '05 and once in a while I see the VDC off, Slip, and SES lights on. Now it says to "Service Engine Soon". I'm taking it into the dealership tomorrow morning. They say that it may be caused by low brake-fluids; I'm hoping that this is the case since that's an extremely quick fix. I hope my throttle body sensor isn't shot yet.

I'll find out and repost to update my situation.

 

Stupid question, but going FI and then getting these same problems, it won't be covered by warranty, correct?

 

I just got mine back last week, bad TBS. Infiniti replaced the whole throttle body (warranty). Apparently, they've had some problems with this.

 

Oh, I just saw the other threads, looks like you all are having the same problem

 

I have a question. Does everyone who have a TBS problem happen to have a dirty air filter? I just realized mine is very dirty even though it only has 12K miles on it and the manual says change it at 15 K.

Another guess, I wash my car myself and many times I accidentally spray water through the grille into the engine compartment. Can this be a potential cause for TBS breakdown?

 

I doubt it, but what do I know.

I brought my car into the dealership today and it's confirmed that the throttle body went bad.

To recap, the VDC OFF, Slip, and SES lights were illuminated. This eventually led to the "Service Engine Soon" light being illuminated. Brought the car into the dealer early in the morning and they fixed it up in less than an hour.

Good stuff.

 

less than an hour? wow they had to order a new throttle body for mine and I was without my car for 3 days.

I was lucky that they had the part on hand. Going in at 7:30am in the morning helped also (first customer of the day).

I think my car had a faulty throttle body from the day of purchase. Now that it's replaced, I can really hear the air flowing and now it doesn't struggle to move in 1st gear. Thank goodness.

 

I will just add my story. I was pulling out of Schnuck (grocery store in Midwest) and the same thing happened on Sunday. It was the $838 throttle body fixed the next day while I had a G35x loaner.

 

Seems like a common thing. Do all of you guys have 05's?
