Had my J11b QQ for a week now, not had any problems with the emergency brake apart from one. In the UK we've recently had storm Ciara and this weekend is storm Denis, so the weather has been awful. I was driving along the motorway about 50mph in the POURING rain and the system came up with a warning saying radar was obstructed and was now offline. Can only assume this was due to the torrential rain as the car is brand new and there was nothing stuck to the Nissan badge at the front (where the radar is) when I stopped.

Have heard a few stories about this particular function going barmy in the rain, anyone else had any similar experiences?

You'll get the same effect with Satellite DTV signals, and some radars if the rainfall (obstructions) are severe enough. Radar returns are sufficiently disrupted/weakened to cause the system error(s) detection to kick in. Pity the design doesn't show a "system ok" message after such events...if it is ok (no/less errors) that is?

For military radars there is a way to get around raindrops (literally)...not so for car radars though.

Xenon102, our QQ was picked up new in Dec 19 and as yet we have had no AEB problems, as today if there is rain / moisture I just go around with a tissue and clean the Badge, Cameras and Sensors, it is a habit I got into with the QQ J11A. There is also the Nissan AEB Recall but ours appears to be out of the dates concerned - Dave 🤨

Thanks, you're right now system ok message, but cleared for the next trip anyway, i'll keep an eye on it ;)

Thanks for the tip, i'll have to remember that! My QQ is brand new also, any idea how I can check the AEB Recall details? is it done by VIN or anything? Also struggling to determine for sure the build date...

Xenon102, I think we are safe regarding the dates and generally do not panic if there has been no recall or contact from Nissan. I normally take a drive to our Dealer and Speak to the Service Mgr. (with the written information) or you can contact and ask NCS - Dave 😏

Regarding the AEB the comment is that the cars were manufactured at different production periods between November 8, 2016, and June 5, 2019. The update the software of the “Intelligent Emergency Braking” (IEB) system lasts 45 minutes and the action with the internal code “P9327”.
These are official Recalls :
You could try playing with this - Nissan VIN Check « Car Recalls EU : https://car-recalls.eu/vin-check-recalls/nissan/

Check if a vehicle, part or accessory has been recalled - GOV.UK : https://www.gov.uk/check-vehicle-recall

Yesterday I was in a Hospital Multi Park House and to say the very least it was all very tight, even driving in and getting a ticket the QQ Alarms were going off. Anyway I drove in behind another “Oldie” who wanted to park as most do by the entrance, he parked with some difficulty, I waited for the Brake Lights to go out and started to drive forward. Well the QQ accelerated but the “Oldie” started then to reverse and the QQ done a standing on its nose job, full brakes with flashing red lights, just like an Emergency Full Stop. So now I assume the AEB does work as it should and now very confident - Dave 😉 ✅

It’s looks also like these people in their Tesla were also lucky.
