Hi Folks I have 2 issues with my car and I wonder if anyone else has experienced either of them. It has just come back from its costly 3 year service at an Infiniti service (Nissan) dealer and I sort of hoped this may have improved things especially when I mentioned both faults to them. The dealer said both things are 'normal' but this is hard to believe. I have 10 weeks of the manufacturers warranty left, hence my unease !!

1) The best way to describe this is if say you are driving round a carpark slowly looking for a parking space, walking pace or slower, it is as though 1st gear keeps disengaging which can be proved as you can sometimes rev the engine a little and the car doesn't move forward with the revs. The dealer says this is normal as the car has a double clutch which can sense whether the car needs drive or not. Its unnerving as there isn't really a way of knowing whether you have drive or not at slow speeds.

2) More worryingly, when you go to pull out of a junction (remember this is an auto !!) the car hesitates and almost cut out, especially worse if the junction is on a hill. You cannot pull away cleanly at all it always hesitates to a lesser or greater extent then you end up shooting forward.

If anyone has experienced or can comment on either of these problems I would be really grateful, if the slipping in and out of 1st gear is normal then that's fine, but I do wonder whether the Nissan dealer just maybe can't be bothered given that it's not a Nissan. I had a manual Infiniti 1.5D before which was absolutely faultless in 4 years, I prayed this one would be the same or better.
Any replies or comments appreciated.

Hi I have a QX30 Auto 2018 and have never encountered this.Sounds like the dealer is fobbing you off.I'd go back and demand a fix under warranty.

Hi I have same model but a year older.I can drive at a similar speed and the car is very smooth
with no hint of disengaging from gear.However what I have noticed on a very steep hill the
gearbox can’t hold the car and it slips back a bit and more throttle is required to take off.
Im not a transmission specialist but I know transmission level is crucial in these gearboxes
as well as the condition of the oil.
Does the car drive off on level road without throttle when you put it in drive?

It does creep forward when i engage drive on the flat for sure, but in the car park scenario the gearbox definitely disengages and re-engages very noticeably as the revs drop. I do feel that i am being misled by the dealer.

I agree also on the autobox not working correctly. Was it hot weather? What mileage?
These are one of the best boxed you can get. With the correct software dealer can read the gearbox oil temp and oil level and also run a relearn procedure for shift mechanism. You can buy a calibrated dipstick also to check level manually. Software was supplied to certain dealers so they should have a trained technician there. There is also a reset procedure on internet as box auto updates last 40 shifts on driving style, you can wipe this data with reset procedure.
The dealers are terrible - as in no investigation skills? try a mercedes independent as they could do a report for you are capable to read the levels? Does it have a leak?
Gearbox service is around £350 and recommended every 5yr 60k I think. Failing that measure what comes out and refill with new, is a start. Comma do the correct oil.
Hope you sort this 🖐

Thank you all for your help with this especially Cornish Blue, you are a legend. A quick update, the car went back to the Infiniti service dealer last week, they connected up the diagnostic plug and it showed up absolutely nothing. However, they then called some guy who is an Infiniti technical manager and he instructed them to do some sort of master reset on the car which they explained resets 'everything' back to factory settings. I have to say the car is at least 95% better, if not 100%, but the problem has been such a pain I can't be sure !! Luckily it was still just about in warranty so no worries.
My beautiful car is now the pride and joy of my life (don't tell my significant other that I said this !!)
