SERVICE BRAKES

Potential Consequences:

While driving on the highway a message came up stating Brake System Failure, top speed 62 mph. It also came up with other error messages, like service traction control. I completely lost any braking capability and had to let it slow down & pull off to the side of the highway. I shutoff the vehicle and then restarted it & everything seemed fine. I took it to the dealership right away, where they said it had about 20 communication codes across different systems. After 3 days of them having it, they have no idea what is going on. They are now test driving my truck to see if they can get it to happen again (which could kill someone if it does happen again).

FUEL/PROPULSION SYSTEM

Potential Consequences:

Engine stops running due to a known problem with GM's Fuel Pump Control Module. The unexpected shutting off of the engine poses a serious risk to passengers and other vehicles while operation on all roads. There are numerous vehicles in the service centers of all GM dealerships with the exact same failed part. The three month backlog on receiving parts is indicative that GM knows about this problem and has not issued recalls.

UNKNOWN OR OTHER

Potential Consequences:

This vehicle has an electronic tailgate release mechanism. This is the 1/2 ton version of GMC ‘s pickup. The tailgate releases randomly and opens, generally while driving down the highway. I have dump the contents of the truck bed on the road immediately in front of vehicles which are behind me, causing serious handling and collision issues for the trailing vehicles. No accidents have occurred yet. When I have called the GMC dealer, they inform me that the electronic tailgate release mechanism HAS BEEN RECALLED ON OTHER GMC TRUCKS for this EXACT reason but NOT for my model. While they will repair the device if they can get it to fail in the shop(which it wont), they will NOT replace it under warranty because it has not been recalled. How can this be?? It is clearly a recall issue and should be included in the recall program.

STRUCTURE:BODY

Potential Consequences:

My 2023 Sierra has an issue with the tailgate opening at any given time while in park. The dealer denied such issue until I noted a GM recall on the tailgate switch becoming contaminated with water. My issue is the amount of items, such as tools, half full plastic gas cans, shovel, etc, that I have lost out the rear of my vehicle endangering other motorists. My tailgate has become damaged, mostly paint damage, however I am more concerned about the public's safety and other GM trucks with the same growing issue. It was not until my dead battery (in a 2023 vehicle) caused me to discover the tailgate issue was connected to the short in the release switch. I also have a tonneau cover so I cannot see the tailgate and the truck gives no indication of the tailgate being down. This problem began within a few months after purchase.

ENGINE

Potential Consequences:

While driving my 2023 GMC Sierra 1500 Denali, 6.2-liter engine on the highway, the engine seized at 22,000 miles. GMC has been working on my truck since 9/7/24 and still no truck. The end state is, I was told by the Service Department that there is a design flaw with the 6.2-liter engine (something with the intakes valves being too large, resulting in the valve bending seizing the engine). I was also told, this dealer had two other trucks there now with the same seized engine. Their plan is to install a new engine with the same design flaw with the hopes it does not happen again. This was an extremely unsafe condition as I was travelling at 65 miles per hour on the highway when the engine seized, luckily, I was able to coast to a large shoulder after almost getting into an accident when it seized going uphill.

STEERING

Potential Consequences:

While at highways speeds, the steering will not return to center while going/coming out of a curve. It acts as if the power steering system is failing or low on fluid but that is not the case. I’m aware of a current recall with the Sierra but my VIN does not fall into the recall. The recall is for a software fix. GMC will not look into without charging me. This is a safety issue while driving. It holds the steering wheel in the turning position and I have to pull it to center.
