anyone still have problems with engine jerking ? mine after 1 year and countless complain still come back :-(

Welcome to my club 
I had this similar problem...

My ride is Jun 2012 model and initially it had this jerking problem (and once in a while in slow driving, mostly in traffic jams, could feel like a big gear slip sort of feeling, eventhough this is gearless  ), and they changed the OCV for me but as the problem persists, they reflashed the ECU and TCU and the problem got resolved.
Then, exactly one year later the same problem started again so I had to bring it back and got resoled after they reflashed (or updated again) the ECU.

My car is having lot of electronic fittings as I changed the whole Alarm system to 'Easycar' which comes with the Keyless and push button start etc, and Auto Wiper, Auto light etc... So always when checks for error codes, it shows Immobilizer errors which SC always complains  ,  so I thought that the ECU updates somehow have got reset due to some overwriting from one of my additional fittings. Anyway the SC in Singapore is kind enough to do the update free for me.

After the updates, the jerking is gone but still have some issues if I Reverse and forward a few times in fast speed..... which I can bear
