Toyota Centurion Incompetence

<p>This is the 3rd time I've written the same complaint on Hello Peter & the 9th time I've taken my 2015 Etios back to Toyota Centurion to "fix" the over revving at idle. I am now convinced that Toyota do not have a clue how to fix this problem. My dillema is that when the warranty runs out the computer will pack up due to this problem and I will be left holding the rotten egg. I have escalated to Barloworld HO with no luck. I am at my wits end and I believe I need to seek Legal advise now, which is a costly affair.</p>
