qx56 loses power/turns off while driving by cspring
Sep 21, 2008 (10:22 am)

I have a 2005 QX56 83k miles on it. Has anyone else had the following problem:
While driving along at around 50-60 mph the car will suddenly lose power or turn off. The 4wd drive indicator the check engine soon and brake indicator all blink rapidly.
I then glide to the side of the road put car in park and restart the car as if nothing happened.
 
It has happened 3x, after the first time I brought it in, but nothing showed on the diagnostic. It happened again 2x yesterday along with a hiccup at speed. I want to say it has something to do with the transmission, but that's a guess. all indicators and gauges are normal except when it loses power.
 
Has this happened to anybody else and what is wrong. Thanks.

has anyone experience annoying rattles of the dvd screen when driving? I have a 2008 QX and the rattling is very distracting...I literally have to wedge a rag behind the screen to soften the sound.

I had paint peeling from the rear bumper of my '04 and they replaced the bumper when I scheduled routine service.

4 wheel drive high or low?
When engaging or disengaging 4 wheel drive low, remember to have the transmission in the neutral position or it will indicate it is engaged, but it won't be.

Ive had the same problem as cspring, except with a 2004 QX56 with 100k miles on it. The dealer is perplexed, thought initially it was problems with the sensors, which were replaced. The car ran great for a week but then shut down again. Any ideas on what this may be?

I have a 2005 QX56, about 105000 miles. This same problem started on my vehicle last week - 3 days at the dealer, not fixed. It happened again this week, another 3 days in the shop.
I know that brake systems and fuel systems are quite different functionally, however I have had a similar problem with my brakes for about 3 years - brakes make nose when pushed, brake and ABS lights come on. I go to the side of the road, turn off the car, turn it on again, and the problem disappears. I had always felt that it was some controller in the car that was having a glitch of some sort. This fuel problem is very reminiscent of the same kind of activity - seems like an electrical/control problem, and turning the car off and then on again makes it go away. Both problems happen only occasionally, and the dealer has never been able to reproduce the problem and consequently never able to fix it.
 
However, I called Infiniti Consumer Affairs - 1-800-662-6200 option 7 and told them of the issues. The dealer called yesterday and said that Infiniti had instructed them to check out a control module as well as the fuel pump. I received a call this morning indicating that they are going to replace the fuel pump and the IPPM ( a control module). The IPPM is evidently involved with both the fuel system and the brake system. Infiniti is going to cover the cost of replacement.
 
If you don't hear from me, the problems have not reoccurred. I'll reply again if I continue to have problems.
 
Good luck - hope you can solve the problems on your vehicles.
