GMC Complaints

On my 2023 GMC Yukon, XL the infotainment screen freezes and you have no access to any vehicle information, including rearview camera. This issue appeared three months after I purchased a vehicle in 2023 and was taken to the dealership confirmed the issue, but said the resolution was to do a hard reset on the infotainment center. After driving the car for three years and taking the advice of the dealership and resetting the infotainment center every few weeks, the problem escalated and started freezing up at least once a week to eventually doing it every day and the heart reset wouldn’t always work the first time. Dealership eventually confirmed it was a defective radio module. This is a very large vehicle and the rearview camera is an essential necessity to avoid collision.

GM performed a vehicle wide Over the Air reprogramming of the modules incorporated in the VIP/Global B electronics platform in April, 2026. Following that my vehicle became totally dead. Key fob would not unlock the vehicle. Had to use the metal key, open the drivers door. Opened the door, nothing moved. No lights, no movement from anything on the vehicle. Opened the hood, charged the battery and tried to crank it. Would not budge. Starter would not engage. Disconnected the negative battery cable. Tried again. Still would not budge. After an hour of so of trying and using jumper cables from our other vehicle, still would not budge. I disconnected the negative battery cable from the right front fender ground and reattached it. It then cranked. Drove the vehicle 30 miles at interstate speed. 8 miles in city traffic. Drove home and parked it in the garage. Drove it abput 10-12 days later to get breakfast. Parked it, locked it with the key fob. Came back after getting food, key fob would not work. Opened it with the button on the door handle. Got In tried to crank it. Would not budge. Disconnected the negative battery cable twice, before it cranked, but would not drive. Message in dash said vehicle could not be driven. Finally got it cranked. GM never advised that the battery must have a 70% charge at all times for the electronics to work. Owner's manual contains no such statement. Vehicle is defective to the extent that it will leave me stranded in wherever the battery power is less than 70%. Dangerous to get stranded at night on a lonely road or highway, away from cities with tow trucks and competent service personnel. Vehicle in shop 32 days before dealer advised resolution. Modules bricked requiring engine control module and telematics module replacement.

My truck is intermittently having the camera display a warning code. While in reverse or while towing and trying to use the surrounding cameras. It happens randomly and almost caused accidents in parking lots. While towing I use it for lane changes and with non towing mirrors it’s a very dangerous issue that could cause an accident especially on the highway

Engine temp rises way above mid-level and will stay there for several minutes before cooling back down to normal temps. 2 different mechanic shops have told me it's the coolant control valve, but want $2500 to fix it. This service bulletin is for the same year, make, model, and motor as my truck, but the dealership said it wasn't covered.

Our onstar module has stopped working since last November after a software update and now issues are starting to cascade causing many other electrical issues to the point that I expect the car to leave my wife and 15 month old daughter stranded. Ours and many other vehicles are having this issue and when any question is asked to gm no response is given or we’re just told to keep waiting.
