Stop/start unavailable Ford Ka 1.2 2016

[Woj]

I wonder if anyone can point me in the right direction.

After driving for 5-60mins with no issues I come to a stop at traffic lights or roundabouts etc. then there's: 1. A loud beeping noise. 2. The dashboard engine warning light comes on 3. Shows error "hill holder system unavailable" 4. And "auto start/stop system unavailable"

When I accelerate and release the clutch as per usual the car gets stuck at 2mph then pressing harder on the accelerator causes the car to stall.

I need to turn the engine on/off several times for the warnings to disappear and to accelerate normally again.

This can happen several time a day for several days in a row or once every few weeks.

Ford ran a diagnostics test and didn't find anything. The clutch has been checked as well, there's no slippage.

Any ideas what could cause this?

Hi, I am currently facing this issue with my Ford ka. Did you get to the bottom of what the problem was? Thanks

Replace the car battery with a new one, or fully charge the battery you have for at least 12 hours.
