I have owned my Q50 for just over a week. Up until tonight, I would describe it as a "perfect car". No lockups, great driving car and in every way, better than my G37.

My car is premium with Deluxe Touring. I was driving my 12 year old daughter to cheerleading practice tonight. I started up my car, waited about 15 seconds (did not wait until all apps have loaded) and pulled out of my garage. I felt something very strange. The car defaults to standard mode which makes the steering wheel much lighter than sport mode or my personal mode.

I noticed that wheel felt very "heavy", but as I pulled out of my driveway it is when I realized the steering wheel, while difficult to turn, was not responsive. I was able to pull to the side of the road and got the warning: "Chassis Control System Error - see owner's manual". Nothing like having this kind of malfunction in the car when you are driving the most precious thing in the world around.

I turned the car off and waited a few seconds, restarted the car and waited about 30 seconds and then all was fine.

I took a photo of the error message on my iphone and will be emailing it to my dealer in the morning. I think the cause of this was pulling out of my drive way before the system was fully "booted up". I have attached the photos. The second photo shows the steering wheel lit up with an exclamation point next to it.

That's a bummer make me wonder if they hired a PC OS company to design the car's electronics. I find the delay for the radio turning on annoying, much less the steering.

The DAS is an aautonomous system independent of in touch apps. The only thin the in touch system would do is send an receive data to and from DAS. Waiting for apps to complete loading would have nothing to do with the failure.

Your situation is more likely a hardware failure of the DAS system.

The DAS has tripple redundant systems to make sure this sort of thing does not happen.


Get infiniti tech involved ASAP for all our sakes.

I have my car going into the tech on the 12th. This has only happened to me once but I had no steering at all. I will post my experience after the 12 in my original thread.
Did you get the same warning that I did? This only reason I am not totally freaking out is that the problem occurred right at the start, not when I was driving in the middle of a trip.

Well perhaps it needs a quadruple redundant system? This is getting ridiculous

If, somehow, the mechanical clutch that connects the steering wheel to the steering rack did not disengage, then the DAS would error when the car is started.

The system works like truck air brakes. Air brakes are normally on until air pressure is applied.

In the same way, the DAS system is normally mechanically linked until the car is started and electrical power disengages the clutch.

In both reported cases, it sounds like the steering clutch
did not disengage.

If I am right (not saying I am) this condition will only happen at startup.

Not sure of the warning. More concerned with the ups truck I most plowed into. Put into reverse to get back into my parking spot. Shut down and restarted. Wheel worked following. Dealership said they could not find a problem and return to customer. I have been on the phone with Infiniti customer affairs about 30 times. Is getting nowhere. If this tech does not solve my problem or find a problem I will fall under Texas lemon law. 3 visits to a dealership for electrical issues that have not been solved. Not to mention a serious safety hazard. That was the state of Texas comment about my car. We shall see.

Razorburn26,

It would be interesting to know if your steering wheel was torqued to one side or another. What I mean to say is if the steering wheel was turned after the car was parked and turned off, then the clutch might be torqued and cause a problem on restart.

It is just a theory that might explain what happened and why the dealer could not duplicate the problem.

Hmmm... That kind of makes sense and doesn't sound too far fetched, but this is coming from someone who has never driven the car (Me just to be clear). But you may be on to something.

Seriously!!. When ever I make up my mind and decide to pull the trigger I see these steering lock up issues.
Feel bad for the OP. I am glad nobody got hurt. Infiniti needs to come out and address these issues.

Not once have I waited for intouch to load before I drive off. So I dont think not waiting for the apps to load has anything to do with the system lockup?

Glad that no one got hurt. HUGE liability issue for Infiniti if someone does because of this.

As a lawyer, I can see some of the issues that the Q50 is having brewing into a class action lawsuit.

This was on another post concerning DAS issue.

I have had DAS start up issues 4 times in my car. Never while driving. The symptom being a couple of warning lights on and a very rough / mechanical feel to the steering. I could still turn the car but it was clearly not happy.
Turning the car off / on corrected it. The dealer said it was related to low battery faults before i bought the car (Infinti reps concurred) and they did a re teach to the DAS and returned the car to me. That was 10 days ago and time will tell if it's corrected.

Could this be your issue as well?

sometimes I think Infiniti should have just stuck with the steering from the G37. I liked my steering. Why fix what isn't broken? -__-
That is why I'm only considering the regular steering option. Very similar in feel to the G37, only slightly lighter. Problem is, if you want a basic convenience option like memory seats you must order the DAS.

Yeah, from what it sounds like here I'm so glad that I've got the simpler Q50 Premium (just w/ Nav and sport wheels) with no other added packages so by default I ended up with the older traditional steering. Haven't had a serious problem with the Intouch taking too long to load either. Seems like it comes up within 10-20s after ignition.

I sent an email with the photos of the error screen to the dealer where I purchased the vehicle. He left me a very detailed voicemail and said there were two possible causes: 1) low battery. 2) Moving the steering 90 degrees one way and then 90 degrees the other. Either way, the solution is the same. Turn car off and restart. I know I don't have low battery, but I may have turned the wheel sharply coming out of my garage. The good news is that I think this only happens at start up. I am going to keep my eye on it and will report back if there are other issues.

My dealer told me the trouble codes stated low battery. When I asked for a printout he said they were out of tonner. I have called multiple times for the printout but will not receive a call back.

As far as my steering wheel position. I had backed into a parking spot and can not imagine the wheel was more then 10° to the left or right when I turned off the ignition.
