The contact owns a 2014 GMC Acadia. The contact received notification of NHTSA Campaign Number: 23V334000 (Air Bags) however, the part to do the recall repair was not yet available. The local dealer was made aware of the issue and confirmed that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

Multi-function tailgate lowers without warning. Issue has occurred four times over the past week. The first issue resulted in cosmetic damage to the upper part of the gate.

I purchased my Sierra in 2021 and 2 weeks after purchase I got a warning for service stabilitrk and another for trailer brake system. This is very very annoying and also has my abs light on. My next issue is a code u510 for active grille shutter assembly. Please fix these issues as they are very common and unsafe. Not to mention as much ad I paid for this truck.

Brake control module disconnects trailer brakes while towing. Apparently a known issue with trailers equipped with solar battery chargers which have higher charge than vehicle battery. It feeds back into the trailer brake power module causing it to shut down. The vehicle has an integrated trailer brake controller as it is specifically designed with primary function as a tow vehicle. Shutting down the integrated trailer brake controller results in loss of trailer brakes. Not having trailer brakes is critically dangerous. GM has issued a TSB #23-NA-149 specifically addressing this known defect. Unfortunately, GM refuses to authorize its service technicians to replace the defective brake controller unless they experience the defect personally - the policy is to disbelieve the customer with the defective vehicle. Effectively, this requires providing the trailer to the service tech to drive around until the brakes fail, thus creating another dangerous situation for a tech who may or may not have experience driving vehicles over 50’ in length. Thus, it would appear the best remedy is to enforce a recall to replace the defective brake controller before someone is harm by loss of brakes, since GM requires its techs to encounter a loss of brakes before authorization of replacement of the known defective unit. This happened over 25 times during a trip last week. This fact situation reveals why your Administration actually exists - to protect the public from harm.

Side Blind Zone Warning in Driver’s side mirror constantly alerts(turns on) when driving on a highway next to guardrails without any other vehicles nearby. Extremely disturbing at night.

What component or system failed or malfunctioned, and is it available for inspection upon request? The Infotainment system continuously changes screens without being touched. No matter what screen is displayed, it will change on it's own to various other screens. How was your safety or the safety of others put at risk? While I was driving I was using my GPS via CarPlay and the directions were displayed on the Infotainment screen. The screen started changing to other screens and at one point changed to the back up camera. I was almost in an accident because I was unable to see the directions and frightened and confused when the back up camera appeared while I was going forward on the highway. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, I took the car to the dealership while it was still under warranty and they told me it was due to me using CarPlay and that my iPhone just needed to be updated. I updated my phone and the problem never went away. So now I've stopped using CarPlay and the problem is still occurring. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Only the dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warnings. The problem first appeared in late 2020 early 2021. I have a video recording of the issue as well. Also when I Google the issue lots of other owners are complaining of the same issue.

I am writing to complain about that General Motors has issued a retrofit program for 2022 model vehicles that did not come with safety features due to the microchip shortage. I purchased my vehicle new in 2021 and the vehicle did not have the option of having safety features at the time of purchase. I find not having the safety features in a large vehicle to be a safety concern for those that use the vehicle or around the vehicle. General Motors should add the 2021 model vehicles that also did not have the ability to have those features on them added as a part of their retrofit program.

it’s the lifters that are collapsed and The lifters are pitted because the camshaft is cracked. So in couple months some of my friends who owned GMC Yukon had same problem. I think this problem become a common problem need to investigated by GMC and the cost should paid by GMC no matter it’s in guaranteed or not. Repair cost is around 10000$.

1.)Rear Brakes are not functioning properly. They still have pads but when you press down to pump the brake it fails. I was told by a mechanic that they other GMC vehicles have had recalls on this, but mine is not showing one. 2.)The suspension on this vehicle has never worked properly. It rides extremely rough. It has some special suspension in it from a shock perspective, but it feels as if it often fails. 3.) I had to replace the torque converter in this vehicle last year, and the fluid that runs through it. Apparently this is a known issue with no recall. 4.) the transmission slips when the vehicle shifts gears. It shifts hard. Also a known issue with no recall.

I just purchased a used 2021 GMC Sierra after having for a month the SERVICE POWER STEERING came on, I took it in for service and was told the part is on back order. Not to worried if the dealership and GM sold it to me that way. I am going to drive it and hope and pray that nothing bad happens. And if it does i will be getting a Lawyer.
