Question about 2008 Hyundai Sonata
Check engine light goes on car has 65,000 miles on it, was told engine has sludge in it Why? it's only 4yrs old we do reg oil changes. Is there a prob with the 2008 sonata engines
There are two main causes for sludge, not changing the oil and filter at regular times, and not running the engine long enough to get it hot.
You might want to get a second opinion from a shop other than the dealer. The dealer may have a sales promotion on engine flushes this month.

hyundai bumper to bumper warranty is 5yrs 60k miles with 100k powertrain for original owner. unless you have an extended warranty it is not covered. there is actually a tsb for adjustment on the brake lamp switch
