Is this a known problem?
The manufacturer has sent NHTSA 1 service bulletin or notice for the 2023 Chevrolet Colorado that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
This service bulletin provides information for the technicians to use a Customer Concern Verification sheet to facilitate the questions needing to be answered by the customer regarding Automatic Emergency Braking (AEB) issues.
What owners wrote
“Recall was performed on truck about a year ago for the pedestrian collision automatic braking. Today the truck locked up the brakes in traffic and there wasnât a pedestrian in sight. I believe the recall didnt truly fix the issue, as it has given false alerts before without applying the brakes”

“Radiator inlet hose leaked which caused low coolant. Check light alerted. Replace the hose. Parts are on backorder. Also had a recall on the emergency brake assist. I took this in for the recall however the alert assist still goes off.”

“When driving through an intersection, the vehicle incorrectly applied the automatic emergency braking system. There was no risk of crash, however the application of the hard braking in the intersection put me at risk of a rear collision. I do see that the new recall is supposed to address this issue.”
Filed Apr 12, 2024
“Twice in the first 6000 miles this vehicle has suddenly activated the forward collision avoidance system with emergency breaking although no cars were around. Fortunately a vehicle wasnât behind me otherwise there may have been a collision. I took the vehicle in for service with this complaint and the dealership simply said they could not reproduce the issue during a test drive. Obviously this wasnât helpful.”

Should you keep driving it?
This page can't tell you that. 1 of 26 reports involved a crash and 4 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
