<IMPORTANT UPDATE>
I just got back my car from the dealership and I am just starting to connect the dots.
Back in February I left my Stinger for scheduled maintenance at KIA Glendale,CA.
I asked them to check and perform all the open TSB at the time.
One of those open TSB was the SA333 "Theta 2.0L turbo AFT warmer connector replacement".
When I picked up my car back in February, the invoice listed SA333 as "completed" (see scan of the invoice attached).
Last week, my Stinger engine overheated and has been towed to KIA Alhambra where they looked into the issue.
I found out this morning that my car is ready and that the problem was a pipe leak that caused the engine to overheat.
The pipe leak is directly related to this SA333 which KIA Alhambra service performed (replaced the pipe and seals/o-rings).
It could have been worse (head gasket or melted heads).
What I am trying to understand now is if the first dealer (KIA Glendale, February 2018) lied and did not perform the service action or if the instructions they were given back then by KIA did not solve the problem (are there any differences between the SA333 from February and now?).
I encourage every 2.0T owner to have this issue taken care of as soon as possible, as it WILL eventually result in coolant leakage sooner or later and potentially much bigger engine issues.
One last word about it: this incident does not make me feel much trust in KIA and their dealership network.
This is my first KIA and, if both KIA Corporate and their dealership network attitude does not change, it will be the last.
PS: KIA Corporate never contacted me back despite making an open claim on their website.
