Hi i having a problem with ford ka 2014 when the bad weather comes my sometime show 3 lights on dashboard auto + engine light + triangle my car needs reboot than ok to drive does anyone help me cheers Paul. 

As your car is based 100% on the Fiat 500 I would suggest looking on the Fiat 500 forums to see if it's a known issue

It does seem to be an issue on here over the years. Several threads on warning light problems, but not consistently the same ones. Causes mentioned include poor earth, faulty light bulbs, low battery charge and - very commonly - faulty instrument cluster. Several firms offering a repair service which seems to.indicate how common the problem is.

Similar picture (as you might expect) over on Fiat 500 forums.

(Don't know if Lyndon ( @rd457 ) on here can help with these?)

I've had a few people enquire with me before about repairing them (Mk2 Ka units), and I've explained that as I've never actually been sent one yet I can't be certain whether or not it would likely have cracked joints and whether or not I could do anything to solve their problem, and then each time I've then never heard back from them again, so I still don't know. 😕
