There is only a maximum for the terms in office for the German President ( two times five years) while that is a mostly ceremonial office. Angela Merkel has recently opted for a third full four-year term and could have a fourth if she won the next election and age and energy permitted.
But Germany has a Parliamentary system, not a Presidential system like the US. That means that a Chancellor can only remain in office as long as the Parliament has confidence in him/her or in the Govenrment he/she leads and as long as his/her party or coalition has a majority in Parliament.
Parliament can at any time decide to cast a vote of non-confidence on the Government and end a Chancellor's tenure at a stroke. Also disastrous results of the Chancellor's party in State elections may cause the members of that party to lose confidence in his/her leadership and to choose another leader, which will invariably result in the immediate stepping down of the Chancellor.
