Is it going to fail like the Mars rovers that are still running or is it really going to fail?

Sometimes these things have what is called a TBO (time between overhauls) versus a true MTF (mean time between failure), which is routinely applied to aircraft engines.
With a TBO, the engine is inspected, repaired, and even replaced at so-many hours of use, even if it is working perfectly.
With a MTF, this is a mean value, and does not mean a failure is imminent when this time has been surpassed. Hard-drives have the same ratings, usually like 20,000 hours or so. But I've seen drives rated at 20,000 hours run continuously for 5 times that, yet others failed at 1,000 hours!

For the benefit of anyone else who Google's "QuickSat", it's actually spelled "QuikSCAT".
