Consumer Description

When autopilot is engaged (I don't know if just cruise does this) on a highway entrance set to a reasonable speed like 35 or 45, as I approach the acceleration ramp the setting jumps to 90 and then quickly back to 85. I've found no reason to beleive that the car won't accelerate up to 85. There is no way for the driver to make such a jump. Driver is only able to jump in 1 or 5 mph increments. I have no trouble disengaging autopilot, but still... This has been going on for weeks, and despite a software update or two. I can provide video of this happening but I don't think I can upload it here.
