2016 LINCOLN MKC Vehicle Speed Control Problems

My 2016 Lincoln MKC has a recall. Recall was mailed to me and I called closest Lincoln dealership to begin process. Dealership stated part was on back order and I would get a call when it comes in. I called a few weeks later and still no luck. I attempted calling several times with no luck. Fast forward 2-3 months after calling, I’m driving with my son and out of nowhere the car begins to stall while driving and fumes start coming out from air vents. It was an awful and strong smell. As I pulled over the check engine and battery light came on. I had vehicle towed to dealership which they return with a catalytic converter code. I paid to get replaced and get a call that car is good to go, but recall part is still not available. Picked up my vehicle and didn’t make it more...

Two things are a problem: 1) When adaptive or regular cruise control is set to a particular speed (any speed) and the increase speed (+) button is pressed once or pushed and held, the vehicle increases speed and does not stop unless cruise control is turned off or the brake pedal is pressed. 2) There are multiple problems associated with the SYNC system (maps no longer work, Bluetooth connection is spotty, delays when turning on and off the radio, system stays on after leaving the vehicle).
