My 2012 Sonata, it has the 2.4 GDI engine, which has known issues with connecting rod bearings spinning and engines seizing. Both Sonata and Kia Optima models, as well as Santa Fe Sport and Sorento, are models affected. The problem also affects the 2.0 turbo engines of the same model vehicles.
Recall notices have been issued by the manufacturer and the government. What the ultimate recall action will be is still unknown, however, Hyundai has issued a warranty extension to 10 years/120K miles for the engine. I think Kia has gone one further and upped the coverage to 15 years unlimited miles for the particular defects people are seeing.
That said, people are waiting 2-3 months to get their engines replaced once they go. The long blocks are backordered and there is a waiting list. They will give you a loaner car while you're waiting however no guarantee of what it is - one guy on the Hyundai forum got an Accent, for example.
I would like to avoid this outcome until the manufacturer and government agree on the ultimate recall action on these engines. I don't want to be without my car for several months. So being a BITOGer I am switching from the recommended 5w20 (stamped on fill cap) to the allowed by owner's manual 5w30 and I will be doing analysis, just got my first sample yesterday evening and will be sending it to NAPA analysis. For the record, I put in 5 qts of M1 5w30, why, because my engine is DI and a magnesium heavy oil is supposed to be better for LSPI. Oh and it was sitting on my shelf already.
I plan to set some more conservative condemnation limits on it than I have with my past cars. These are the factors I am considering.
-Fuel dilution (Engine is DI): 3%? 5%? Ignore as long as wear numbers are good?
-TBN: change when TBN crosses TAN? or a certain number? 4.0? 3.0?
-Viscosity: Out of grade for 30wt? ( -Wear metals: Any bearing related wear metals above universal averages?
-Flash Point:
Any other factors you would consider for condemnation limits based on UOA?
Driving profile:
About 50 miles per day, long commute at mostly freeway speed, so this *should* be pretty easy on the oil. More mixed driving on the weekends.
