The vehicle was taken to a dealer; however, the cause of the failure was not determined after 8 weeks. The manufacturer was not notified of the failure. The failure mileage was approximately 34,000.
The active cruise control does not appear to be able to be completely turned off, you can only cancel a particular speed you have set. I have experienced multiple times in a parking lot situation when trying to park that as steering wheel was spinning, it is very easy to hit the toggle switch that sets/resumes the cruise control, at that point vehicle may acclerate to the set point as you are trying to park. You must quickly either hit the cancel button or the brake to disengage the cruise control that you have no intention of engaging. Although I have been able to get the situation under control, had another moving car or pedestrian been close by, not sure if I would have same result. I have gone through the operating manual provided with the vehicle, and from what I can tell, there is nothing in the manual that even tells you how to operate the active cruise control. It seems like there needs a “system off switch” so the set/resume button is not active, until the system is turned on. I have owned many GMC Products, and none have had the design where the toggle switch sticks out from the steering wheel and is easily inadvertently engaged. Usually the controls are flat/smooth like the “cancel” button on this vehicle…….which can’t easily be engaged accidentally. Luckly, I have not had a crash or injured a pedestrian
While driving on the interstate, my vehicle started losing speed. I pulled over to the shoulder of the interstate and put in neutral so I could coast further to the exit ramp where I would be in a safer location. My vehicle has 14037 miles on the odometer and has now gone through 2 engines. It has always been serviced by GM.
The issues with my vehicle began when the radio intermittently cut off or froze. Despite several attempts by the dealer to resolve the problem, they were unsuccessful. Early on, various electrical components failed to load or perform correctly, with the dealer attributing this to software updates. Currently, when the radio cuts off or freezes, I experience additional problems: the headlights randomly flash between dim and bright, the heads-up display fails to load or shows incomplete information, the collision detection activates with no objects around, and dynamic cruise control becomes unreliable or fails to engage. The wipers operate randomly, and the vehicle stalls when the auto start/stop feature is engaged. Random warning lights appear on the dash, and each day brings new, different issues. A new symptom involves the vehicle not recognizing the keys are inside, causing it to shut off and lock me inside. This recently happened while I was driving at low speed in a parking lot, which poses a serious safety risk. On the interstate, safety issues are more concerning: headlights flashing on and off, dynamic cruise control failing, BLIS and collision control activating unexpectedly, and the vehicle locking me inside with keys in the truck. My children are scared to ride in the vehicle due to these issues. The dealer claims they cannot replicate the problems, despite videos I’ve provided showing malfunctions. They acknowledge the issues but blame them on software updates. Multiple updates have been applied, but the problems continue and are becoming more frequent, affecting more systems. The vehicle is under warranty, but as of December 13, 2024, the dealer has refused to service it. After the dealer completed some work, an independent inspection confirmed the issues persist. Warning messages and malfunctioning lamps have been captured on video. Problem has been reported from first service approximately 6/2023 as radio malfunction / electrical issues
Purchased vehicle new June 23 2023 and Super Cruise never worked and if engaged acted erratically . Vehicle spent over 40 days in several GM dealerships for the issue and one dealer even charged me for installing a warranty part.. GM filled a case 9-10220813020 but were not helpful in dealing with dealers and to add insult to injury would not even reimburse me for warranty work or in any way compensate me for my time and efforts to fix the issue. Frustrated with GMs indifference I traded the vehicle in March 2024.
The contact owns a 2023 GMC Sierra 1500. The contact stated that while operating the vehicle, the rearview camera, front view camera, and side view cameras became inoperable. The vehicle was taken to the local dealer to be diagnosed. The contact was informed that the camera module needed to be replaced; however, the part to fix the vehicle was not available. The manufacturer was notified of the failure. The failure mileage was 8,500.
Front blind spot visibility is dangerous and GMC does not provide a forward facing camera standard. Blind spot warning also not standard and visibility is subpar.
Traveling at 70 mph on cruise control, tapped breaks to turn off, multiple warning lights flashed, vehicle lost power, and breaks with multiple messages including “Break system failure, top speed 62 mph”. I lost all breaking control on the highway and nearly crashed into other vehicles due to inability to stop. Was able to pull over, turn off vehicle, and turn back on, when the breaks were working again but the vehicles acceleration was very slow. Currently at authorized repair shop. When dropped off, there were 8-9 active codes.
Truck has died going down the road at 40mph. Also have electrical issues with radio..running boards opening going down the road. No sound from radio, signals ...no connections to google on star lost. Radio screen half of screen shuts off. Front crash sensors go off with noting in front of vehicle...loss of cameras no connection. Sounds like a bug zapper under truck. Gm has reprogrammed truck now 3 times sent a tech from factory...replaced radio reprogrammed all computers again!! Truck has been in the shop this time for over 30 days with 6200 miles on it this is the 4th time since I bought in june. Have a case representative from gm who will not help with issues just keeps putting me off. Have videos pictures of all the issues and have given to dealer and gm
The infotainment system loses all audio through the speakers intermittently. when this happens I also lose the Safety warning chimes as well. shutting off the vehicle for an extended period of time resets something and it resumes normal function. I have contacted GM customer service and spoke to 3 different representatives and requested an escalation to a Senior Advisor, which i was told could take up to 4 days to hear back. the vehicle has 800 miles and is 1 month old, this has occurred 4 times. it has not been looked at by the manufacturer as i am waiting for return communication. Other than no sound, everything else on the touch screen seemed to be working normal, but im no technician to determine that. i feel this is a safety concern as i travel with my 13 month old daily.
