JA: Have you checked the battery, particularly the terminal connections? Are they corroded?

JA: Are you fixing your Tucson yourself? What have you tried so far?

Hello, when your Tucson didn't start was it cranking over and not starting, or were you hearing a single click and it was not even trying to start?

Customer: replied 7 months ago.
No cranking over. No click. 12.5 on volt meter

It was very cold when this happens.

Alright, it sounds to me like the starter solenoid is sticking and that is why you are not able to start the vehicle. Basically the solenoid is a plunger inside of a tube, and it can get stuck once it is worn which will cause nothing to happen when you try to start the vehicle, even if you have good voltage. It probably happens more when it is cold because all of the metal is contracting and it would be harder for it to move anyway. I would recommend replacing the starter and seeing if the issue returns.

Hi Andrew, I appreciate your answer but I don't know if it going to work until I replace the starter. The problem is that's it's been slightly warmer ( I live in Ontario so not much warmer) but now it starts everyday. If it does it again in the next few days that starter will be replaced thanks to your suggestion. No problem with rating you then sir! That ok?
