GMC Canyon adaptive cruise problems

Filed May 20, 2025 · Driver assistance · UT

While driving a two lane road the adaptive cruise control detects oncoming traffic and improperly slows down or breaks unnecessarily. Most of the time the vehicle breaks so hard it will jolts me forward in my seat. I fear another car will be behind me and this will cause an accident. I have had my vehicle in the shop two (2) times to repair the issue. The dealership/service department has been able to replicate the issue by having one of their technicians drive the vehicle. The front camera has been replaced twice and I have been told every time they plug a new camera in the trucks interior and exterior lights "go crazy and flash". GM's response to this issue is "set the gap to mid" or simply "shut it off". They refuse to see this as an issue. Doing my research I found that the 2023 GMC Canyons have been recalled due to the same issue. I have brought this information to the sales department. However due to not being able to find this on General Motors website I have been told by the dealership/service department, and owner of the dealership that the information I found on the federal safety agency is insufficient and they can not go off this information.

On [XXX] I took a trip with family through Ohio from Pennsylvania. While truck was in adaptive cruise control on highway, phantom braking occurred where truck slowed down from 70mph to about 60mph 5 times. No objects or vehicles in front of truck or around truck during the braking. The weather was mostly clear overcast at times with no rain or snow. Concerned if vehicles were behind me during the breaking causing an accident. It was abrupt completely out of the blue when it happened. Took truck into service on 1/8/25 for oil change and braking issue, dealership states there’s no service bulletin for issue. I have not used adaptive cruise control since.

Adaptive Cruise Control has applied brakes multiple times while cruise has been sent at speeds ranging from 55-75 MPH. Vehicle aggressively slowed down 10-20 MPH then picked up speed. No vehicles in sight ahead of vehicle, aggressively applied braking without warning. Aggressive braking could cause traffic behind vehicle to crash into me while driving at high speeds. Multiple other reports of this happening to other 2023-2024 GMC Canyon owners based on comments on Facebook and Reddit with acknowledgement from the manufacturer that this is a know issue they currently are trying to resolve. Issue not isolated to this vehicle. Vehicle has not been inspected by Manufacturer or problem been reproduced dealership. Vehicle goes in for service next week, meanwhile cruise is not being used as it is a safety hazard. No collision warning or any other warnings experienced with this issue. Issue first happened on day 1 of vehicle ownership and has happened 2-3 other times with one instance of it braking and accelerating 3 times over a 2-3 mile stretch of highway with cruise set at 75MPH with vehicle slowing down to around 55MPH before resuming set speed.

Headlights flicker all the time regardless of speed Radar cruise control will slam on the brakes for no reason even when there's nothing in front of me. (Seems to happen more at night) Blindspot monitoring will randomly turn on for no reason

I was driving with my cruise control set at 77 mph in the fast lane of a four-lane highway. There was no one in front of me for more than 3/4 of a mile. A car in the lane to my right apparently triggered the automatic breaking system to the point it slammed on my brakes, pushed me into the steering wheel, and slowed me all the way to 38 mph in the fast lane of the freeway. The result of this unrequested breaking caused four cars behind me to almost rear end me and pile up. The second event was going down the freeway with the cruise control set at 65 and nobody around me and the car again slammed the brakes on for no apparent reason. At this point I’m afraid to drive the car. I have zero confidence in this vehicle letting me operate the vehicle. I need help.

The contact owns a 2023 GMC Canyon. The contact stated while driving 20 MPH, while making a right turn, the left turn signal activated and blinked three times. The contact stated that the Adaptive Cruise Control intermittently activated the brakes independently, and the Forward Collision Avoidance system activated and forced the vehicle to stop abruptly, almost causing a crash. The Forward Collision Avoidance warning light was illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure and informed the contact that the parts to repair the vehicle were on backorder. The failure mileage was approximately 2,251.

My husband recently asked if I had encountered any problems using the cruise control in this vehicle. Since I seldom drive any distance with that vehicle, I never noticed anything. But he had traveled onto the interstate, and when attempting to set the cruise, noticed it didn't work. Yesterday, I had to follow him somewhere, and I noticed the brake lights weren't coming on. We tested all the other things (tail lights, back up lights, turn signals), and everything was working properly. Today I was looking to see how to replace the brake light switch, and also noticed there were instructions on how to replace the cruise control switch and fuses,too (as they all seem to be related.) Then I found that some models of the Chevy Colorado and the GMC Canyon were affected by a recall for this same issue. When I looked it up just now, this model (2009 GMC Canyon) is not under the recall (but it has the same issue).

Transmission experiences torque convertor shudder. With very hard shifts at 5 and 18 MPH. Dealer complied with bulletin 18-na-355. Had improvement in shift for a while. Then hard shift return at 5 and 18 MPH. During decelerations there would be a shudder. When using cruise control when reducing speed transmission would shudder. Return to dealer, when oil pan was removed found aluminum chips and one metal chip. Dealer replace with remanufactured transmission. Drove vehicle home.

"cruise control" went out and I cannot find out where the problem is. The fuses are excellent. While I was driving I had the cruise control on, then all of a sudden for no reason the green illumination on the dash that let's me know it's on, was off. I tried to engage the cruise control again but that did not work. The green illumination on the dash does not come on anymore even as I attempt to engage the cruise control. I was on the highway at the time this happened.

2015 gmc canyon crew can 4 wd has intermittently had power steering fail. My wife has almost wrecked twice due to not being able to steer vehicle. Called dealer & was tolls " it's not safety issue nor is it covered under warranty. Wife was driving on freeway at @ 65-70 MPH on all 6 times this has happened. With cruise control on & suddenly lights come on the dash & it becomes very difficult to turn the vehicle, making it very unsafe for anyone to drive especially if you don't have great strength to turn wheel.
