2017 GMC YUKON XL Vehicle Speed Control Problems

Adaptive cruise control system is not properly designed to recognize vehicles that are adjacent to the traveling lane and not directly in front of the vehicle. When traveling on the interstate with adaptive cruise engaged, we came around a bend in the road approaching an entrance ramp. There was a slow moving vehicle on the entrance ramp which was apparently identified by the adaptive cruise system as being in front of our vehicle in the same lane. The adaptive cruise caused our vehicle to brake violently while still in the bend in the road, which in turn caused us to swerve into the next lane where there was a car traveling adjacent, but just behind us. This was a very unexpected series of events, and could have resulted in catastrophic consequences had the adjacent car been any closer at the time. This is a major flaw in the adaptive cruise...

THE VEHICLE STARTED TO PULL ALL THE WAY TO THE RIGHT SIDE WHILE DRIVING ON THE 710 FREEWAY IN LONG BEACH, A NOISE STARTED TO BE AUDIBLY HEARD WHILE I WAS DRIVING. I I CONTACTED THE EXECUTIVE OFFICES OF GENERAL MOTORS AND NOBODY COULD ASSIST ME WITH THE REPAIRING THIS VEHICLE. I WAS TOLD THERE IS NO REMEDY FOR THIS ISSUE.

TRANSMISSION WENT OUT AT 88K MILES. MY SISTER IN LAW ALSO HAS A 2017 BOUGHT FROM ANOTHER STATE AND IT WENT OUT AT 79K MILES A WEEK AFTER MINE. PASSENGER SIDE TAIL LIGHT WORKS IF YOU PUSH ON IT THEN RANDOMLY GOES OUT (WIRING/ELECTRICAL ISSUE). OF COURSE THE DRIVERS SIDE TAIL LIGHT IS THE ONLY ONE ON RECALL. CRUISE CONTROL SET ITSELF AT OVER 100MPH AND RAPIDLY ACCELERATED UNTIL I HIT THE BRAKES. I RECEIVED A RECALL FOR THE BREAKING SYSTEM SPECIFICALLY FOR MY VIN NUMBER THAT NEEDS TO BE FIXED NOW THAT MY TRANSMISSION IS COMPLETE.

WHILE DRIVING AT VARIOUS SPEEDS, THE VEHICLE DASH DISPLAYED NUMEROUS AND RANDOM ERROR MESSAGES: (WORDING MAY NOT BE EXACT) SERVICE FRONT COLLISION SYSTEM. FRONT RADAR BLOCKED. FRONT COLLISION SYSTEM UNAVAILABLE. THESE MESSAGES INDICATED A PROBLEM WITH THE FORWARD COLLISION AVOIDANCE SYSTEM. THE WEATHER ON THE PARTICULAR DAY VARIED. ERRORS OCCURRED AT VARIOUS SPEEDS. THIS HAZARD CAN CAUSE SERIOUS HARM IF THE SENSORS DETECT AN IMMINENT FORWARD CRASH IN ERROR AND APPLY THE BRAKES IN TRAFFIC. THIS DANGEROUS SITUATION IS LIKELY TO RESULT IN SERIOUS PERSONAL INJURY OR DEATH. THE ROOT CAUSE WAS DETERMINED TO BE RELATED TO AN ADDITIONAL FAILURE MODE IDENTIFIED IN THE OILY SUBSTANCE LEAKING FROM THE CONTROL BOX MOUNTED ON THE FRONT WINDSHIELD. THIS OILY SUBSTANCE WAS IDENTIFIED BY THE VEHICLE OWNER AND REPORTED TO THE DEALER.
