I bought my MY11 LR4 HSE in March of 2014. It had 30K miles at the time. Since then I have put about 53K add'l miles on it. I would estimate at least 50% of those miles are highway miles. In the last 2 weeks or so, every time I start it, I get a brief alert in the center dash message center. The first time it said: "Service Required in 1500 miles" Since then it has counted down and currently says 600 miles. I have never seen an alert like this in the last 50K+ miles I've driven this vehicle. Is there some critical service interval at 83K miles? I have had all my usual services done per schedule. Everything after warranty expired has been done by my indy shop. I don't think they have reset any service alerts in the vehicle's computer. Could it be telling me it's ready for transmission fluid flush and change? It sounds and runs as well as it ever has. Thanks in advance. PS: Last oil change was at 81K (done by me), and was PRIOR to the onset of this alert, FWIW.
