Adaptive Cruise Control problems of the 2023 Chevrolet Colorado

1. Other: turn signal - when turning right with the signal activated, once you straighten the wheel, the turn signal stalk will reset to the middle but will activate the left turn signal. 2. Adaptive cruise control - for no reason the brakes will activate, there is no vehicle in front and the windshield is clean. 3. Blind spot warning - these bsw indicators will go off at random with no vehicles beside mine. This occurs more at night, but does happen during the day. When this happens at night the yellow indicator is so bright that you cannot even see what might (or is not) in your blind spot. This faulty indicator is going to get someone hurt as other drivers with the same issue might over correct.

#1 adaptive cruise control suddenly brakes when there are no vehicles ahead. #2 after completing right turn with right turn signal flashing the left turn signal is activated and flashes three times.

Signal on to turn right. Turn completed and left signal turned on by itself. Driving on freeway, cruise set 65mph, lane keep assist turns off without warning. Veered into shoulder unexpectedly.

Dash cluster initially went blank while driving and there was no speedometer or console. The vehicle alarm was also reported as going off in the middle of the night without anything around the vehicle. I took it into the dealership and they replaced several parts including the dash and radio components. They also performed a front camera recall repair. A few weeks later after driving around 250 more miles, we were driving in traffic around 50 mph when all of a sudden the vehicle came to a complete stop with no foot on the brake and injured my husbands neck and my wrists from how abrupt the stop was. The vehicle basically shut down and had to be restarted several times to get it to start back up again. Had roadside assistance tow it into the dealership again and they said that it happened during their test drive of the vehicle as well and was beeping and stopping at shadows on the ground. They drove it about 65 miles before it did it again. They returned the vehicle to us, unable to repair the issue and the gm technical engineer told them to just turn off all of the safety features in the console and that I would have to make sure they were turned off before driving the vehicle every time or if it lost power. They turned off the emergency braking controls with this action. Asked me to also adjust the gap to mid for object detection. They replaced the front camera with the recall and it still did not fix the issue. They told me that my truck does not have adaptive cruise control but the devices were acting like I did. I don't know if this is true or it is just another excuse. Note- this is the 2nd chevy Colorado that I have had in 6 months with same issues as the dealer replaced the first lemon after 2 months.

About 4-6 times while traveling a 170 mile stretch of I-25 from castle rock to trinidad CO the vehicle will automatically brake from 75 mph to 65-70 mph when using adaptive cruise control. There is nothing in the road ahead of the vehicle. The automatic braking then releases and the speed resumes to 75 mph. This has happened on each trip since the purchasing the vehicle new in October 2023. Most recent incident was 04/04/2024.
