The contact owns a 2024 GMC Canyon. While the contact’s son was driving approximately 35 mph, the brake pedal was depressed; however, the vehicle failed to slow for a traffic signal and the brake pedal was stiff. The contact stated that his son needed to use force to depress the brake pedal. There were several unknown warning lights on the instrument cluster. The contact stated that the phone app showed a failure with the abs. The contact stated that the failure was intermittent. The vehicle was taken to a local dealer. The dealer was not able to duplicate the failure and cleared the codes from the warning lights but provided no information on the fault codes. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 11,000.

Since I purchased the vehicle it’s had the issue of it braking on its own. I brought this up to GMC many times. At the beginning they had me try to duplicate it with them, which I thought would be unsafe. They only acknowledged the problem and attempted repairs after I contacted GMC directly. The issue with the crash alerts while driving always stayed, even though there was nothing in front of me. Just recently it started braking on its own again in traffic. This has caused bodily and property damage, luckily nothing grave. I do not feel safe in the vehicle and gave GMC many attempts at fixing such a serious issue. I want them to tow replace the vehicle and provide a loaner. Please contact me if you need more details. [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S.

Battery dies during vehicle update spontanteniouly. After jumoing vehicle to start it all systems will not return to normal causing brakes not to function normally. I jumped my vehicle after one system update and brakes failed to engage almost causing an acident. These vehicles should not be on the road due to the software safety flaws. GMC is aware of this and still have no fix for the problem. There are numerous accounts of this happening to this vehicle on forums and solcial media.

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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2016 GMC Canyon. The contact stated while driving 65 mph, the abs, and service stabili-trak warning lights were illuminated.

Vehicle was brought in 7/29/24 for park assist code dealer found short in wire. Dealer stated that to fix wire would require taking cab and bed off frame. Dealer ran a new wire along frame to avoid fixing properly. Vehicle picked up 8/1/24. Vehicle brought in 9/10/24 for a variety of sensors activated. Dealer stated to me that anti-lock brake module was on national back order and not expected until 10/28/24. Ut was not safe to drive the vehicle, and they have had the vehicle from 9/10/24. Also, drivers power window module has to be replaced. This 2024 Canyon has been a problem. I have contacted gm and asked for a buyback of the vehicle which gm refused.

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.

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 that when applying the brake pedal, the steering wheel would begin shaking. The computer on the center council that displays information, had blacked out. The vehicle was taken to the dealer who diagnosed that the brake pads had failed. The dealer had completed a software update for the main computer however the failure persisted. The vehicle was not repaired due to the brake pads (part number 87850375) not being in production for repairs. The failure had become more persistent and now the brakes have failed. The dealer was contacted and confirmed that the part for the repair was unavailable even for purchase. The parts were on national backorder. The vehicle had not been repaired. The manufacturer was made aware of the failure by the dealer and the manufacturer confirmed that the part was unavailable. The failure mileage was unknown.

Automatic breaking system. Driving along at 25-30 mph on a snow covered road when all of a sudden alert system sounded and vehicle brakes abruptly applied putting vehicle into an uncontrollable slide. Fortunately there was no one behind and nom on coming traffic. Notified gm customer service, as I have a case open for other issues they claim tyhey do not have a fix for. Gm's response to the sudden brake application was "OH I'm sorry".

Service brake assist light comes on and vehicle loses braking power. Brake pedal gets hard and unable to stop if needed and has potential of injury / accidental death. This similar problem has been recalled in the larger trucks /suvs due to safety issues. It appears it's also happening in the smaller truck's Canyon and colorado's as well, however no recalls. Many blogs online discussing the issues and failures of the braking system.

Driving down the road and power (electric) steering goes out. Power steering and traction control warnings lit up on the display. Almost impossible to steer without power steering. I am lucky that this didn't cause an accident-- very scary. This seems to be the same issue as the recall for the 2015s, but gm didn't recall the 2016s (even though online forums report that it was the same part number for 2016 as 2015). Reported same codes when the truck was the same as those reported by others (c0545: steering wheel torque sensor, also u0420: invalid data reported from steering control module). Upload button below disappears when I try to upload my invoice--but invoice included remove and replace of rack and pinion, diagnosis, alignment-- total invoice $2003. 78.

Vehicle only two months old with 2000 miles. Service engine light and brake assist service light activated. GMC dealer states brake master cyclinder failure and vehicle should not be driven. Vehicle left at dealer while awaiting replacement master cyclinder. Unknown if this is a widespread problem causing brake failures in GMC and chevy new model Canyons and colorados.

During normal operations the truck will come to a complete stop. I turned off the abs and it still happens. It caused a major incident today while I was driving 50mph and it brought me to an abrupt stop on the highway. It’s happened many times but today the driver behind me avoided my truck by an inch. I was then followed y that driver for half a mile when I immediately exited the highway.

Emergency collison fault problem on the 2023 GMC Canyon failure date: 10/22/2023 driving approximately 45mph while car in front is approximately 50 yards ahead driving at a matched speed as my vehicle and without any prior warning the forward collision alert activated flashing red light on windshield and automatically applying full braking until the truck came to a complete abrupt stop in the center lane of rush hour traffic causing other drivers behind to swerve narrowly avoiding serious accident. I manually DE-activated the automatic braking but kept forward alert on until the truck could be brought to the dealership for diagnosis. Forward alert went off erroneously multiple times the following days without any rhyme or reason. Not until the final day before the scheduled service appointment did the system DE activate itself indicating an issue with the forward collision. Dealer now has vehicle in their possession and confirmed a fault issue. They are working with gm on a solution, but no luck yet.

Driving approximately 45mph while car in front is approximately 50 yards ahead driving at a matched speed as my vehicle and without any prior warning the forward collision alert activated flashing red light on windshield and automatically applying full braking until the truck came to a complete abrupt stop in the center lane of rush hour traffic causing other drivers behind to swerve narrowly avoiding serious accident. Had the cars been following closer or an 18 wheeler been behind me during this incident, the outcome could have been much worse. I manually DE-activated the automatic braking but kept forward alert on until the truck could be brought to the dealership for diagnosis. Forward alert went off erroneously multiple times the following days without any rhyme or reason. Not until the final day before the scheduled service appointment did the system DE activate itself indicating an issue with the forward collision. Most issues occurred while it was either raining or damp outside. Dealer now has vehicle in their possession and confirmed a faulty component that is on backorder with no date. Truck has had multiple other electrical issues since purchase 3 months ago. ~200 miles dealer replaced faulty hvac module. ~4500 miles forward collision alert as described above. Since day one there have also been issues with trailering harness intermittently not working causing trailer brakes to not function while towing. (yet to be diagnosed by dealer) lastly left turn signal would stick causing turn signal to stay on until manual deactivation. Dealer confirmed faulty turn signal and is in the process of replacing while it is in for service.

The contact owns a 2023 GMC Canyon. The contact stated that the vehicle had experienced several electrical failures and the vehicle would not start due to a faulty battery which had lost power. After the manufactures over the air electrical update was performed the vehicle began to experience several additional safety malfunctions which included the backup camera, door locks, brakes and power steering. The contact indicated that while driving approximately 5 mph the warning messages "power brake assist" and "power steering" had displayed and when pressing the brake pedal the pedal extended to the floor and the vehicle would not immediately stop. Also, the steering wheel became stiffer to turn. The vehicle was later taken to the local dealer who indicated that the vehicle had experienced unknown electrical failures but no solutions were available. The manufacturer was also notified of the failures but no assistance was offered. The failure mileage was 2,500.

Constantly getting a message and beeping to service my trailer brake system while in park and driving. I’ve never used this before for towing any trailers or anything. This message and beeping cause a distraction and I find it to be dangerous. And the fact I’ve never used this is quite annoying.

The brakes locked up and stayed locked for several minutes about 6 times when the brake peddle was lightly touched. I was told by the dealership service department that the computer needed reprogramming. A software glitch caused the brakes to lock up? not very confident in this product!!! I am trading in this GMC for a Ford.

This is the 4th time I have had a problem with my brakes. The brake pedal will be extremely hard to push to brake and this has happened while driving. The brake booster has been replaced 3 times now and is now at the dealership, where they have discovered that this is happening due to the break booster pump being bad. Now we get to add another $900 to this truck towards this problem. I am really surprised that there is no recall for this. This truck us not that old and we have had problems since we've owned it.

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).

As I started the vehicle I got a notification that the power steering has maldonado I got a few warning lights on the dashboard. As I drove the vehicle the power steering did not work and it makes it hard to steer. This has been happening for a week now.

We have a 2017 GMC Canyon diesel with 56570 miles on it. While we were driving down the street (it was raining) going about 30 miles an hour and all of the sudden the "service stabilitrak" censor came on am it instantly put the brake on. We turned the truck on and off. Over and over letting it sit for more that a minute completely and still nothing. . . . We were down the street from our house and my husband had to push it home. This could have been such a dangerous situation 😳 there happened to be no one behind us but it was so abrupt that if we did they most definitely wouldn't have had time to stop and crashed right into us. I will be calling GMC in the morning but we were definitely grateful we made it home safely though pushing a truck through the rain up hill was not fun for my husband. We have read up on this and was completely surprised how many people have had this same problem. You definitely should have something put out for this letting people know. . . . This is crazy gm has either basically ignored this or simply does not care for safety. I absolutely love my truck but this truly disappoints me I hope we are not put in the same situation as all these other folks who were put through the ringer with no result for this issue!.

No brake fluid had repaired by deal in one week same issues no brake fluid onstar diagnostic report and alerts say brake system error noneno error code foundnone abs - braking and stability systemc0273an issue has been detected in the traction control system. Service within 7 days got this today pulled over no fluid driving 30 mph on city street I have all onstar and mechanics report�s.

I was parked. When I started the truck I put it in reverse. While backing up I applied the brakes. The power for the brakes was gone. I had to slam as hard as I could to stop the truck. A very scary situation. I heard there was a recall for this problem. I went to this website to find out. It states there are no recalls on this truck. This is a very dangerous problem. If GMC puts a product out like this they should fix the problem. I took it to the dealer all he said to me was it dangerous and it would cost this much to check it out. Nothing about it was a recall or not. Please let me know if this is on them as I still have to drive the truck.

Abs fault I have replaced brakes wheel hubs and sensers 2 times in 3 months still abs fault 98,000 miles on truck this issue is all over the internet needs to be addressed.

When you start your truck up let it warm up you start driving down the road and you touch the brakes and the rpm start going up and down up and down with vehicle dying sporadically.

"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.
