I've had similar issues as others for the past few months..

From October to January, there was probably 3 incidents when I started the car in the morning, and I had no steering, and my traction control light was on. All three times, I would restart the car, and go about my day

2-3 weeks ago, it did it again, but it wouldnt go away. Cold start in the morning, no steering. After the car warmed up for a few minutes, I restarted, and was good to go. I wasn't happy, brought it to the dealer

They said they rectified it with a software update. Didn't review the paperwork, but should still have the invoice somewhere

This morning, was a different story...

Granted, it was cold out, but I started the car, and Traction light and steering light were on, and no DAS. I pressed the ignition button to reset, and things went terribly wrong.

The car began to shake violently. It would just up to about 1500rpm, then down to, literally, around 100rpm. Just enough to thing it would shut off, but it would then shake violently and race up to around 1500 rpm. I kept pressing the ignition button, car wouldnt turn off or on

I got out of the car at first, because I was shocked. I never seen anything like this. I had to pump the gas repetitively like an old fuel injected car. After say, 30 seconds of that... car finally kicked on. I immediately turn it off.

Restarted it moments later (had to get to work), and everything was fine. I ventured out to work.

13 miles later, getting off my exit.. .the DAS shut down while driving. Lights came on the dash. I thought I had no steering, but luckily some type of manual steering kicked on. I was able to pull off the road. Restarted, finished my drive, called the dealership...Its going in tomorrow morning.

The one thing I will say, is I never saw the "Chassis Error" everybody had. Not sure if its because I didnt flip to the Error screen, or because I restarted the car right away to fix the issue. Even today, I never saw a Chassis error... just the Traction Control & Steering light came on

Drove home later that day, no issues.

I've had quite a run of new cars, many of them were "New Model Years"... Never had so many issues with a car in my life. Not even with Audi or Benz, the "electrical gremlin kings"

When did you buy the car? Do you have all the latest software updates? Would you buy this car again thinking these bugs will go away?

I got it September 29th

I did the intouch software update a few days later... The inTouch problems were unbelievable for a 2 day old car. I also did another inTouch update in October or November.... it actually did fix, most of the bugs. The screen still blacks out randomly every other week

Then it went in for the steering 2 weeks ago, told me they updated the software..

I dont know yet... I had 5 Acura's, First one was kind of a lemon. Tons of problems with faulty brakes. Car ended up going into a wall from brake complications (faulty OEM equpiment w/ Aftermarket BBK)

Next 4 cars, were a dream to own. So I can completely shut down Infiniti.. but I've definitely got a bitter taste

Errr.. if this happened.
This ins't a DAS problem.
You have a car problem.

First of all if any engine gets down to 100 RPM it will usually stall.
And in general you have a big problem if this actually happened.

This is not at all normal for fuel injection.

This might happen if you have a carbureted car with a horribly out of tune choke.
[edit] Again this is why we drive computerized fuel injected cars with all it's sensors. So this never happens.

My car has done the exact thing you described, but only one time. All other times the DAS has failed to engage but the car started fine.

Like Andrew said, that sounds like the old "pre-ignition" problem that the old type of cars would sometimes have. The way you got the car to finally turn off, was to push the accelerator to the floor. What happened to you just shouldn't have happened.

I would have to agree.

This does not match the descriptions of other commonly experienced problems, and is more likely than not (and hopefully) a one off concern.

There should be a trail of fault codes that someone will have to deal with.

Best of luck with the repair.

Went to dealership this morning, they said my car was recalled. Gave me not much info, said they'll need the car a few days and gave me a G37x

Like others said, it was always a matter or restarting the car, and the code went away... but yesterday, was something else. I know a lot about cars and have done extensive modifications on prior cars myself.... When I was young, I had a 92 Ford with 270,000 miles on it... never did anything like this.

BTW- G37x, better bass on the stereo, and the seats are a little more plush. World of difference between the interiors on the G and Q.... G felt so cheap in comparison

Things were so much different and simpler in the pre-OBDII days. Since 1996 there have been many increases in standards and decreases in fault tolerance thresholds. When I was in school learning this trade it was right around the time OBDII came around, the instructors at the time thought it would be the end of the industry. In reality the evolution has been subtle enough that it is almost possible to compare cars from the early 90s to cars today at some level. It is possible to get a modern car beyond 250K ( I have several clients who have well above that), it will just take more maintenance and upkeep than they used to.

Took them 5 days, to once again, "reprogram" the DAS.

So far, no problems.. but I will say, the steering feels a lot looser than before (even on heavy setting)... and its WAY to responsive on the quick setting

It could just be, that I am used to the G37x I had for the past few days

DAS Scare:

Last night while driving to the store, I noticed my steering was off. While in motion, my car would (very obviously) veer to the right. In order to keep it from veering off the road, I had to wrestle with the wheel to keep it going straight. This is clearly not an alignment issue, but an issue with the "Steer-by-Wire". This happened all the way back home as well, and this morning on my way to work. On the way there I decided to turn around and go straight to the dealership. Mid-way to the dealership...the steering goes back to normal. WHAT?!

My Q50 has a mind of its own. The service rep had a puzzled face, and admitted that Infiniti has not given them much light on what is going on. Anywho, I dropped it off and they are going to run some "tests" to see if they can figure it out. Question is, how can they figure out what's wrong when the car decides to go back to normal the moment I bring it to the dealership??

My car is going on 10K miles now, and it is VERY strange that I'm seeing this issue. I love my car to death and it seriously blows to have to experience these small but very serious and dangerous issues.


Anyone else have this issue?

This exact issue happened to me 2 days ago, and this is the 3rd time in 2 months. I do NOT have the latest DAS update however.

You probably drove next to a high-frequency radar that interrupted the DAS signal for a brief period of time. Car had to "re-learn" itself by driving a few hundred miles. It's normal and nothing to worry about. ;)

.....
Complete bs. Infiniti needs to look into this.

Mine does the same thing--except it pulls typically left, but sometimes right. It is random and intermittent. I have the latest software and hardware; still does it. Not confidence inspiring and not safe. Infiniti says it is "normal" and happens because of the setting I have the car on--That setting is known as "Standard," which as you know is the default for the car.

My car has been back at the dealer since yesterday morning for the multitude of problems I continue to have, and I have non-DAS Q50 loaner. It is amazing, because it goes where I point it without decided to veer to the right or left at random. It also doesn't either randomly apply the brakes or at least display a radar system failure. And it hasn't decided not to turn off the dash yet because it is still looking for a key even though the ignition is switched off. Maybe I should've bought a stripped-down model?

By the way, VBX, I laughed at your radar comment, but I suspect someone was actually told that. I was told that the continued "No Key Detected" problems are because of "baby monitors." While we have those in our house for our 9 month old (who, per my wife, will never ride in my Q50 because of the steering and braking issues; she doesn't want to get in it herself, either), I don't think there are baby monitors all over my part of NY causing this problem to occur in many random places. Even if there were, it would be a sign that something is wrong with their design.

Theres nothing worse than wifey hating your car. It makes you hate it much more, just because you cant even enjoy it with her. Forget her even falling asleep in the car while driving home from a nice night out, she wont even get in the d.amn car.

Well, in fairness, she was uneasy about it for a while because of all the issues with the steering, etc. When the brakes slammed on while we were on the highway heading out to a nice dinner, that was pretty much the end.
I feel for her. My wife is like my life....and she isnt even my wife, she is technically my girlfriend. If she cant ride along with me inside my ride, then the car is worth ZERO to me. Id have Infiniti buy it back in a heartbeat.

Oh, I've already asked them to do that and they say they haven't made yet made an "unreasonable" number of repair attempts. Since then it has been at the dealer most of last week, and went back yesterday because one of the problems it went it for recurred literally 2 minutes after I picked it up there last Friday.
