Hi All,
Hope you are doing good.
From a precautionary perspective, I have decided to go along with the Dealer servicing to keep the Lexus warranty intact. It is pricey but I guess it gives one a peace of mind that if anything was to go off, one has the Warranty to fall back on to cover the mentioned parts as per the Warranty T&Cs.
Thank you to both for sharing your invaluable advice & opinions...
Regards
Sath
