While I've never seen a freeze plug leak on this engine, anything is
possible. I wouldn't be surpirsed, however if an inexperienced tech made
an error. The first time I witnessed a water pump leak on this engine, it
took some effort to find the source. The water pump weep hole connects to
a hole in the block which drains out behind the a/c compressor.
As for the warrantability, I don't see how an integral part of the engine
block isn't covered by the 10/100 warranty.
I ran the number for the only thing that appears to be a freeze plug in
the parts catalog cylinder block picture. I have part# 15732-25001,
"cap-sealing." Per Hyundai, warranty coverage is powertrain, 120 months,
100k miles. What part number did they use for repair?
If the dealership continues to deny powertrain coverage for this repair,
call Hyundai consumer affairs immediately at 1-800-633-5151.
