I have a Australia 2012 hyundai i30 elite CRDI that serve me well for last couple years. I have serviced it at hyundai dealership for every service.

However the dashboard is showing few warning sign (EPS, ABS and traction control warning) recently. I have my last service 1 mo th ago and the 5 years warranty was expiry 2 months ago. I can feel the power steering is stiff than before but other than that the car still driving fine.

What is the root cause for it? I have replace 1 side of my tyre with my spare tyre. Is that going to cause issue to the car?

Was there a problem before changing the tyre? is the spare the same diameter as the other tyre/wheels?

   Also check all your tyre pressures are the same.

Did this problem start  straight after the service? Check those other things then maybe try disconnecting the negative battery terminal for a minimum of 30 minutes to reset the ECU. That might work. Not sure if you will need a code for your radio afterwards though. Good luck.

Spare tire is same size. Both Tyre are the full size Tyre but the spare Tyre has 6mm thread and old Tyre only have 4mm thread. I have replaced the Tyre 6 months ago and the issue only show up few days ago. This morning the warning signs are disappeared again its drive normally now.

The problem still exist

It's alright in the morning, 3~5 degree in Sydney but the warning signs would still occur when I leave work at 6pm (13~15 degree). I am not too sure how to rectify it.

Have you tried all the suggestions in this thread yet?

All the issues were gone after I swapped the spare tyre with old tyre.
