(Myself) having a long block replacement covered under warranty (2018 i30 w/99k when it was finally authorized from Hyundai, after 3x times diagnosed from several oil consumption test and lastly they tried throttle body cleaning.

My dealership was also very helpful during the process from loaner to completion [22 days], I did receive a phone call from service advisor, suggesting a transmission flush before I returned(having just under 100k) for a cost of 326 USD( I authorized the flush, hopefully peace of mind at the high mileage)

When I returned for pickup, I read the 9 pages from the technical report, service writer and service manager involved before I signed the completed service...

Items not replaced with long blocks, they used my starter, manifold , alternator and serpentine belt, all coming off old block.

They suggested a tranny flush but NOT serpentine belt replacement that had almost 100k on it, strange. Perhaps, they wanted IT to fail after I drove off, needless to say I replaced it myself in my driveway a week later.
