I have a 2011 Lexus IS 350 AWD that I bought in January, and I took it in today for an oil change per the dealer’s recommended schedule of just over 4k miles (and to get rid of that red icon and message that popped up and takes up my center display). They found that my engine cover was leaking and took it into the shop for some warranty-covered repair. My question concerns some Recommended Maintenance they suggested…
They suggested that I have my “All Wheel Drive Service” that they recommend at 30,000 miles. (My car is at 41k miles now.) This would entail replacing both the front and rear differential and the transfer case fluids. (The cost to me would be $282.60, if that matters.) I’m not familiar enough with AWDs to judge how necessary or appropriate this work would be. Can the CarTalk team and community help me decide whether or not I should have them perform this maintenance?
