Took the 2008 RRS on a 180 mile round trip today with the family. (Only had the beast for about 3 months) About 2 miles from home I started receiving a trio of messages on the dashboard while city driving. Transmission Fault, HDC System Fault, and Suspension Lowering. RRS still drives great, no noticeable issues. Restarted the engine three different times at stops this evening and the codes would clear for a few minutes and then come back.
I searched a few forums and I can't find a definite answer, should I start with a battery replacement and if that doesn't work, move to the bigger issues? Anybody else receive this trio before?
Also note, the heat index was 106 today so I wonder if that was part of the issue.
