AEB (Automatic Emergency Braking) light randomly comes on which disables the AEB. Since the AEB is a significant part of Cruise Control, it also disables Cruise Control. Having a functioning cruise control is probably not an issue for someone who lives in downtown New York but when you live in Texas and the closest WalMart is 10 - 15 miles away or shopping centers are 30-50 miles away, it is a pain in the ass.
Cruise control is used all of the time. Cruise control has been around for decades. We expect that a cruise control system will work every time because it always has worked. We do not expect that the accelerator will drop to nothing and cruise control to shut off for no reason while cruising down the road. But that is exactly what happens due to the defective AEB.
This appears to be a SOFTWARE and HARDWARE glitch. Software is reliant on the hardware to work correctly and to send valid values. If the hardware sends intermittent error messages, the software has to respond due to the government requirement that vehicles have AEB. BUT AEB should not apply to cruise control. The user should have the choice on whether or not to enable AEB while using cruise control and not simply disable cruise control.
Update from Jan 7, 2021: Appears to disable itself when passing a slower vehicle. It has not, as of now, engaged the brakes. It just beeps, turns on the dash indicator light, and disables itself. When it disables itself, it also disables cruise control.
Update from Jun 13, 2021: For a couple of hundred, the dealership re-aligned the radar systems which corrected the problem.
