My Smart cruise control is not “smart” anymore.
The "famous" problematic brake diode was replaced under a new recall (at least in Canada) and smart cruise control feature is gone. SCC is still working up to the point when the engine can slow down the car by lowering its RPM; when breaks are required to be applied the SCC just disengages.
I suspect that a new item that previous diode was replaced with, just doesn’t let a stop signal to pass through and break lights don’t go ON, then the main computer detects it and decide to disengage SSC; so, the car just rolling.
It took my dealer 2 days to figure it out; when they put back an old diode everything worked fine. They opened an engineering case (I’m not sure if it’s a right word for it) with Hyundai Canada.
Please check your SCC and raise the issue; I think more complaints will speed up the process for a new repair/ recall.
