2018 QX60 shuts down while driving

I have a 2018 QX60, that in the past three days has just shut down while driving in the snow, it just rolls until it comes to a complete stop. The battery light and FEB warning light both come on. The battery is still working (the accessories are still on) but the engine shuts down. The front screen says to push the brake and the start button, as if the car was on by the remote starter, and not actually completely on. Friday it happened twice on my way home, managed to get to the dealership, I was able to push the brake and start button and the car started again. I spent two hours there while they ran numerous tests, all coming back clear. Drove about 300 miles over the weekend (out of town) and had no problems. Yesterday evening, same thing happened, went straight to the dealership. This time it wouldn't restart like on Friday, had to shut it down completely, in the middle of a busy street in rush hour, wait a few minutes and then try to start it again, which it finally did. The car is still at the dealership, they still cannot find anything wrong, and now have three cars in there for the same thing, so there is clearly a problem.

Anyone else having the same problems? Anyone have a solution?

Thanks!

The FEB (Forward Emergency Braking) warning is not a cause for alarm. There is a sensor at the front of our vehicles (those equipped) that emits a continuous beam of either ultrasonic or infrared to a predetermined collision range in front of your vehicle. This is the feature that applies assisted braking when you are approaching an object (vehicle) at a potential collision speed. This sensor can be covered by mud or in snowy condition a film of ice and snow which prevents it from working properly, thus emitting the FEB warning. This happens a few times on my Infiniti FX35 while driving in snow and extreme cold weather when I was residing in NY.

That shut down is scary. Alternator going bad, maybe? Did you try to pull for error codes?

The exact SAME THING happened to me yesterday!!! While driving, in the snow, battery light turned on out of nowhere (no advance warning) and within 5-7 seconds, the car just stopped in the middle of a busy street. I was freaked out, imagine this would happen while driving at 100km per hour on a highway. The event happened twice yesterday within the lapse of 20 minutes, on a busy street. Same thing, car prompted me to press on the brakes and turn on with the starter while the car was still turned on.
I took it this AM to the dealership for verification despite what the technician suggested which was: to drive it around (**** no! i don`t feel safe); or to call roadside assitance (**** no! that would take a few hours of my precious time). I showed up at the dealership anyways, and walked out of there even more stressed than the actual problem, the service was awful and I felt like he was belittling the issue and certainly my concerns. This is a high brand brand which should warrant a certain level of service and ease of comfort in driving a luxury brand car.

Heres my Update.

I took my car to the infiniti Dealership, let me tell you, it was a waste of my time and money, Even after telling them everything they already did to the car last time. The wanted to charged me for 4 more hours of labor to keep digging. I told them to fukc off. 4 hours just to tell me what was wrong. Long story short I told them I wasn't happy with the result and the money I had already paid them. at the end they told me it was the DC/DC converter need it to be replace. about $5,000 and they have to order the part from Japan. I left and didn't pay them sh!t I would NEVER go back to the infiniti DEALERSHIP.
I took my car to a Hybrid Specialist ( By the way my Infiniti Qx60 is Hybrid).
after talking to the mechanic explaining him about what was happening, He knew what need it to be done and where to look. after 1.5 hours of diagnose he gave me 3 options.

1 ) Replace the Body Control Module ( brand New ) about $1,700
2) Get the Body Control Module used and reprogram it ( $1,100 )
3) Install auxiliary relay and inline fuse holder to supply 12 volts to the white wire pin 66 connector M19 of the body control Module ( $700 )

I choose the 3rd option. He told me he done it before and 99% of the time worked. but to make sure told me to leave the car in his shop for the weekend so he can make sure no other error will pop. Monday when I went to pick up the car he told me he had driven the car in the highway at full speed for almost 45 minutes and everything was working fine..

Im a very happy customer the end bill was for $937.82

Is been almost a month and no issues with the car..

Hope this help.

I have a 2017 QX 60, I was driving a freeway speed 75 mph, and all the sudden my radio and dash lights go off and my RPM< and speedometer drop and then it comes back on in a matter of seconds. It has done this at least 10 times in the past 3 weeks. My battery light or nothing like that comes on, but I am wondering if this could be a bad battery cable, as the cables were in horrible dirty shape when i got my car used as a lease trade in. I have a forever warranty through my dealership on the car and one through my credit union. But idk what it is. cause my car still drivees when the dash goes out.

Had exactly the same experience as you on our 2017 QX60 a little over 4 yrs and ~72K miles the cars acceleration suddenly dropped.
Dealer checked and told us engine was dead and needed to be replaced for 12,000$ !
Infiniti Consumer service was a waste of time and essentially bore no responsibility as it was past 70K/7 year factory warranty coverage. I had a third party extended warranty through the dealer that only agreed to partial coverage on a new engine. Replaced the engine a few months ago and still had occasional acceleration issues with the new engine.
Recently the car engine just stopped mid drive in the snow like several other people have posted and would not restart for some time.
Have contacted dealer for resolution.
I would recommend everyone post their complaints/experiences on the US DOT NHTSA website as this could be a major safety issue with Infiniti vehicles.
Here is the link -

It appears the Mass Air Flow sensor was the issue. It's worth asking the dealership for a diagnosis.

"After the dealership had the car for three days, they were finally able to duplicate the shut down and pull an error code. The Mass Air Flow sensor needed to be replaced. They were also able to duplicate it on a second car they had in, same error code."

hey, did it happen in winter only? I got exact same issue since last December. I live in south Ontario, CA. As you said, the engine still run, never stopped unless you power it off. One more symptom, along with the dash off or flashing, I can hear the crackle through speakers, ‘beee…booo…’ like frying beans. Sounds very scary. It’s not battery issue and mechanical issue I guess. Maybe something wrong in electrical system. Did you get it fixed or any clue you can share? thx
Sounds like my car right now:( any insight would be appreciated
