Adaptive Cruise Control problems of the 2022 Chevrolet Trailblazer

The contact owns a 2022 Chevrolet Trailblazer. The contact stated that while driving 70 mph on an open highway with the adaptive cruise control engaged, the system sensed an unknown object and slammed on the brakes. The adaptive cruise control was turned off. The local dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 35,500.

On more than one occasion, my vehicle brakes hard when on adaptive cruise control when approaching a shadow from a tree or over path.

Vehicle is little over one month old and has less than two thousand (2000) miles. Adaptive cruise has been acting erratically. At times going at highway speed on expressway adaptive cruise would apply hard brakes 1. When approaching a overhead bridge. 2. Passing a vehicle in the adjacent lane and 3. Changing lane. Yesterday (10/12/2022) on a higway the instrument panel displayed a warning message "service side detection system". Took it to gm dealer who ran a diagnostic which showed the following codes: 1. B1325 control module power circuit low voltage 2. B317a passenger window switch short to ground 3. U0151 lost communication with inflatable restraint sensing and diagnostic module 4. U 0155 lost communication with instrument cluster 5. U0184 lost communication with radio 6. U0232 lost communication with side object detection control module - left dealer said that these are just notification and may not be able to find anything. It advised to bring vehicle back if this message pops up again.

2022 Trailblazer with approximately 21,000 miles on it. Cruise control fails to engage unless you put your foot behind the break pedal and pull the break pedal forward. This causes safety issues because a person thinks the cruise is engaged but it doesn't actually engage and causes a person to slow on the freeway. Driver also gets distracted trying to troubleshoot the issue because cruise fails to engage without an obvious reason for failure. The fix also causes the driver to operate the vehicle in an unsafe manner because they have to remove their foot from the correct position and place it behind the break pedal to fix the problem. This issue is highly reproducible and was lived with for approximately a year until the solution of pulling the break pedal towards the driver was discovered just last month. Dealer said the issue is nonexistent.
