I own two Rav4's. A 2004 and a 2005. Had them for years and love them. [View all]

BUT, in February, they both started doing something that is driving me crazy. Let me preface this with saying that neither one has any electronics installed....other than any electronic box that came with them from manufacturer. And, definitely no Bluetooth.
Here is the issue that began in Feb. They both start beeping LOUDLY if I go around a curve at what IT considers TOO FAST. Whatever is doing this will also shut down my cruise control.
Does anyone know HOW this was enabled in these two vehicles AND if there is any way to DISable it?
Thanks
