G37 Surges/Fast Idle
I've noticed this happening on occasion too. So when I take it to the service department to get it fixed, what should I tell them? Should I print out the bulletin and bring it to them as well?
That's exactly what I am going to do at my first scheduled service. It happens about 2-3 times a day on my car but not each day, only intermittently after aggressive driving. I imagine that the brake wear is greatly increased by this happening.
It happened 5 times since I got G. Mine is almost 4000miles. I went to dealer 4days ago and explain this problem but they said never heard about it. So I gave them TSB number. after 3 hours... they told me reprogrammed ECU for power train.
Happens to me as well and I live in SoCal where cold is anything below 70. The car seems to want to keep going just before you come to a full stop so I'd guess it's an internal downshifting problem. If I blow a red light and a cop pulls me over I'll just tell him the car didn't want to stop.
Did the problem go away after they reset the ECU
Any news/update on the surging of the G, stopping after resetting the ECU, or taking it into the dealer?????
I am taking my G in for its first service on Saturday....
I am going to tell them about it, and see what they say.

Mine did the same an i have a 6 MT and i reseted my ECU but it still did it...then my SES light kept flashing when i stepped on the gas. so i just took it in to the dealership. all fixed now!!
I also had the intermittent idle surge problem when braking. I took a copy of the TSB to the dealer for the 3750 mile service. They reprogrammed the ECM, as per the TSB and no more problem. The TSB calls for a reprogramming of the ECM with updated software, not just a reset, as some posters have said. The overall shifting of the tranny is MUCH smoother and seems to hold higher revs longer between shifts. Very happy now!



not happen yet. I drive my car carefully at low speed on the local. Just nomal after reprogramming ECU.
