Well, this is awesome. Was driving home from work and my check engine light came on. Connected my bluetooth OBD2 adapter and got the code P0744

I have a '17 Platinum with less than 1000 miles on it. Taking it to the dealer tomorrow morning.

 

Man that is a bummer! Let us know how it comes out. I am curious.

 

I just googled the code, it says "torque converter clutch circuit intermittent DTC", let us know what they say.

 

So apparently the dealership wants "nissan engineers" to look at it because it's such a new car and "they want to make sure it's perfect." They cleared the code and gave me the car back for now and will call me when an engineer can come to the dealership and they want me to bring the car back then.

 

That is very suspect imo. They found something they did not like probably and calling a Nissan engineer. That is not a common thing to do. They should have been honest with you and told you what they found. I would be a bit irritated by just clearing the code and sending you on your way in the mean time. It does not randomly throw a code up like that just because. Especially being brand new.

 

Calm down, they found absolutely nothing. Its a Nissan dealer, all they do is swap parts. These trannies are replaced as a unit, they don't repair anything on them. In order to get new tranny, they need Nissan authorization.

 

Calm down? You think its right they just clear a code then send him on the way? Not telling him what the problem was with that code? You might be an easy push over but that would not slide with me. Just my opinion and nothing personal btw. Like I said it being a brand new car. Its not going to throw an engine light just for the fun of it. Something caused it obviously.

 

Part of an article from a googled search, "torque converter clutch circuit intermittent DTC"

How serious is the P0744 code?

If the P0744 code is detected by the OBD-II scanner, it represents a very serious issue that should not be put off. Issues within the transmission can quickly lead to total transmission failure, and can cause a vehicle to perform less than optimally. If the P0744 is detected, the issue should be addressed right away.

What repairs can fix the P0744 code?

There are many ways that a technician can address a P0744 code, including:
Checking and replacing transmission fluid; if the fluid is found to be very dirty, flushing the system and replacing the torque converter may be required.
Checking and replacing any shorted or faulty wiring, connectors, and circuitry.
Replacing the internal transmission harness.
Finding and repairing any leaks in transmission fluid.
Replacing a defective pump.
Repairing or replacing open or shorted torque converter clutch solenoid valve harness.
Rebuilding or replacing the transmission.
Repairing or replacing a faulty TCM or PCM in rare cases

If that was my car I wouldn't be driving it until the fault was corrected.

 

You took my reply completely out of context. Obviously the car still drives perfectly fine. The Nissan dealer most likely found absolutely nothing out of ordinary, its literally a brand new car with 1k miles on the clock. They have requested Nissan's help and Nissan's engineer is going to check it out.
If there was a reproducible issue with the car, dealer would have requested a new tranny right away. Dealer does not touch insides of these trannies, they are swapped out wholesale.
I have seen nearly new cars throw tranny codes, which were erased to never come back by the dealer.
Nissan dealer is following their protocol, so if you think this would not slide with you, that's fine. Been there, done that, called corporate, screamed at dealers.

Best medicine for me was learning to wrench on my own car. I actually understand dealer's position a lot better now.

If the code will come back on OP's car, most likely outcome will be replacement tranny. Dealer can't tell you something they themselves dont know.

 

No problem. I get what you are saying and understand.

 

sometimes, sending the details of an error code to someone off-site can be misleading. the programmer might not had known a certain issue will occur or how it caused it. for best result, the car should be examined by more than one expert on-site.

off topic.. dealer work order summary said "put tire pressure to manufacturer spec."
nope. coming and leaving with a tire having 30psi, for rotation under warranty.
if not that, they over pressurize, while stating manufacturer spec.

anyways, i hope your car is fine.

 

I'm taking it back to the dealership now and getting a loaner for now. Apparently an Engineer will be there today. I'll keep you guys updated on what happens.

 

So the engineer found nothing wrong. Inspected everything and said there's no issues and he's not sure why the code came on. It has not come on since they cleared the code even after a test drive.

 

not a huge surprise.
If the issue is there, it will happen again.
Just keep it well documented for the future purposes.

 

Can someone help me please, I have a 2016 maxima I though my fog lights went out, so I open the fusebox under the hood pull out the 10amp put in a new one,that didn't do it,so now my check engine light came on is there anything I can do to remove it, thanks ps.and by the way I just have to turn the fog light switch,what and idiot I am.

 

That can really mean just about anything, but if your car is running alright don't panick. For 20 bux at Walmart you can pick up a OBD scanner which will probably tell you what's wrong. Chances are it's just a warning, and if it doesn't look too serious you can use that same tool to clear the error code.
