Roughly every 8 months Sirius XM "radio" runs an automatically triggered free subscription period that includes "weather alerts". These alerts BLOCK part of the car's normal navigational (map) system, requiring UNNECESSARY MOVEMENTS to dismiss the prompts so one can see map details. These movements RISK DRIVING MISTAKES. The weather alerts are unhelpful and unwanted: trivial events that don't affect me. And they keep repeating the same alert multiple times per day. I once called Sirius tech support to have them shut that feature off, but they claimed they couldn't, and to just wait out the promotion period. Sirius XM comes with the car and I can't remove it. I suspect the prompts are a marketing gimmick to trick people into sampling their music channels when they fiddle in the Sirius menus trying to turn off the alerts. Others on social media have reported similar problems in different car models. (PS: I bought the car used in 2019.)

After parking the truck in the garage, the "check power steering," light came on. I immediately lost power steering. I shut the truck off, and about a minute later started it and the power steering worked enough to turn the wheel 1/4t turn to the right and the wheel locked and never moved again. I don't mean hard to turn, I mean would not turn. Had it towed to the dealership in Fairbanks, Alaska and they verified that the wheel would not turn at all. Recommended replacement of the streeting box. There were no prior indicator lights on the truck and little warning of failure. Losing ability to control the truck could have got me in a bad accident. I understand that this was an issue and there was a GMC recall, but my truck was not part of that. The Fairbanks dealership said they never saw one lock up light that before. The truck does have a damaged title due to a house fire and the truck was parked near the garage and it melted the plastics/grill etc. Repairs were made by a certified body shop.

Shortly after the warranty expired my torque converter went out and damaged the transmission. After speaking with several transmission shops this is a known problem with this vehicle! The torque converter and transmission are poorly made, and no matter if you get all of your services this will still happen to you! This should be a recall on this vehicle. Less than 4 years old and I am having to spend over $5,000 to replace a transmission. The vehicle just hit 100,000 miles. If this is a known issue with this vehicle why has it not been recalled? The dealership tried to tell me I just needed battery cables replaced. I decided to get a second and third opinion and as I suspected the transmission is gone. There were NO warning lights, the car just suddenly started not wanting to change gears while driving. At the red light it jumped and wouldn’t move which made the car behind me almost hit me. There were no other symptoms until the gears started not wanting to change. No noises, smells, or any indication that something was wrong. The vehicle is now at a transmission shop awaiting repair. This needs to be a recall if this is a known issue.

GOODYEAR WRANGLER LT275/65R20 LOAD E TREAD ON PASSENGER REAR TIRE PEELED OFF AND CAUSED DAMAGE TO VEHICLE AND THE TRAVEL TRAILER BEING TOWED.

Incident: the drivetrain shudders and experiences hesitation while attempting to accelerate, and car surges forward when breaking due to what seems to be an issue with the tranmission. This present concerns with potential stalling while driving or the car surging into other vehicles. No indicator lights or error codes are displayed. The presence of this problem in multiple GM vehicles is confirmed by service bulletin 18-NA-358. The safety concern related to this defect should warrant a manufacturer recall to fix the know n defective parts. The vehicle has not yet been repaired. Will request to retain defective parts for inspection upon repair.

On May 5, 2024, while driving my 2023 GMC Sierra truck on HWY 40 near Holbrook, AZ, the tailgate lowered un-commanded twice while driving. I called GMC and they told me that my vin is not included in the recall. There is a recall for this exact problem however GMC said it is only for GMCC truck built at a specific plant. This happened twice and did significant damage to my tailgate.
