Hello all, new to the forum. :D
My RX300 has an issue with the cruise control. It works fine, but after about 40 minutes of 70-75mph driving, it suddenly disengages. I can reset it, but then after a minute or so, it disengages again. It will continue this shorter cycle indefinitely. I suspect a heat issue based on the reliable time interval that the failure occurs, but unfortunately, this problem doesn't occur on every trip over 40 minutes. I would appreciate any thoughts regarding this problem. Thanks.
