This is probably a question for Hyundaitech . . .

I am considering the purchase of a new Sonata, and I understand the
Lambda V6 design uses solid lifters (cam followers) instead of
hydraulic. And, if the valves need adjustment in the long-term,
adjustment is a major deal, as the cams must be removed as well as
other ancillary parts. First of all, is this true, and if so, what's
the projected mileage interval for this costly service?

Also, does the new 2.4L 4-cylinder also utilize this design, or does it
use hydraulic lifters?

I would prefer the V6, but if it means costly labor time for
semi-normal items as valve adjustments, I will consider alternatives.

Thanks,
Don
