Hi everyone,
First of all thanks for having me! Long time lurker as a Citroen owner.
We purchased an e-C4 2022 reg this week. All was going well until yesterday it flashed up “adaptive cruise control failure” on the dash and stopped in the middle of me driving. Very luckily no-one went into the back of me. I stopped the engine and started again but the car would only go a small distance before stopping again. Managed to get it to safety and was recovered. We took it to a garage who ran a diagnostics check and picked up a few things. I’ve attached the report. We are trying to get booked into a Citroen service centre to help us but lots of long waits. My question is, the dealership will take it back and refund us if we want or we can go through with updates and repairs under warranty. Has anyone experienced this issue before and had it successfully repaired? Can anyone enlighten us as to the issues on diagnostics and if it’s better to just give it back?
Thanks so much!

My reaction to that rather extensive list and your comment that 'the dealer will take it back and refund us' is bite their hand off and find a different car from a different source. Good luck 
I used to be indecisive, now I'm not so sure!
