Hi, I'm posting this on behalf of my mum who recently purchased a Qashqai Tekna DCI 1.6 Diesel, 17 plate from a local dealership. Since she bought the car she has had to send it back to them for some system faults that come on randomly while she is driving. It flicks between every fault, chassis control, system fault, headlight fault plus others. When this happens the car feels sluggish, has been hard to control at times and felt stiff. She has had it back to the dealership who said they couldn't find an issue with it but replaced the battery to make sure that wasn't the issue and then sent it back to her. She then sent it back to them again for the same issue and they sent it to the Nissan dealership expecting that they would be able to diagnose the problem and they said they couldn't find an issue with it either. It has happened around 6 or 7 times in the last 4-6 weeks and at this point she doesn't know what to do and is trying to find a solution to the problem. I have attached some photos of the issue, if there is any other info that I am missing that would help out please let me know, any help is appreciated, thanks.

 

Not sure what the exact cause is but if it was since replacing the battery then I wonder if they dislodged a connection to the headlight which may be in the vicinity.
Either way, a scan of the vehicle should reveal some fault codes which will guide you to a specific cause

Let us know how you get on with it all

Thanks for the reply, it wasn't since replacing the battery, it happened before this. They said that the battery could be causing the issue so they replaced it. The Nissan garage have taken it in and scanned the vehicle already and said they have found no issues with it which is why we are unsure what to do and what the problem could be. 

Still worth getting the fault codes interpreted which will narrow down the possible cause(s)
