I bought corolla GLI automatic and it's only 5000 km driven. It has very serious knocking sound in first, 2nd and third gear and sometime in 4th gear as well.
I am in islamabad and got 5k km tuning as well, used high octane but no benefit.
Is it manufacturing fault? Toyota islamabad could not do anything. They are giving lame excuses. Their body language clearly indicates that it is manufacturing and permanent mechanical fault.
Need solution as car is under warranty and need urgent reply.
