Ls Spedo Doesn't Match Cruise Control Speed

[sandy2]

I am having a problem with my analog speedometer and the digital adaptive cruise control readout

At highway speeds, the speedometer and the cruise control speed (the speed cruise control is set at) is off by as much as 5mph.

The dealer says this is within the normal range.

Is this a problem, and is there anything I can do?

yea you can be thankfull. Mine is off by about 30mph and it isnt consistant.

Is that really acceptable on a new 120k car?

Blayd, don't you have an older LS and not an 07+ LS600hL? If your speedometer is off by 30MPH thats a completely different issue than the one this member is having.

You may want to post your question in the LS460 forum Sandy, not a whole lot of LS600 hybrid owners here, but a good many LS460 owners who will have the radar cruise and might be able to help you.
