2021 GMC Acadia

The magnetic chest clip does NOT latch. It can easily be pulled apart by hand. It compromises my child’s safety tremendously by allowing the harness straps to slip off of her shoulders in event of a crash leading to a projected infant. Upon doing further research and posting in my moms group on facebook i’ve found countless reports dating back to 2023 where this magnetic chest clip is a terrible design and idea. Many consumers reported to the manufacturer and received multiple replacements and regretted buying the $360+ car seat. It needs recalled and removed IMMEDIATELY before they have an ejected child lawsuit or many.

The contact owns a 2021 GMC Acadia. The contact stated that while driving at 30 MPH, traffic stopped abruptly, and the brake pedal was depressed to the floorboard; however, the vehicle continued to accelerate while the Forward Collision Avoidance warning feature activated with a red warning light on the instrument panel. The contact attempted to steer off the road to avoid a collision; however, the vehicle crashed into the vehicle ahead, resulting in a three-vehicle collision. The air bags did not deploy upon impact. Another driver involved claimed unknown injuries, and the contact sustained whiplash but did not seek medical attention. Police were called, but a police report was not filed at the scene. The vehicle was towed to an independent tow yard. The manufacturer was notified of the failure and stated that the VIN was not included in a recall. The failure mileage was approximately 64,000.

exhaust flex pipe is cracked. Causes fumes of gas to be released through the crack. inspected by GMC Repair shop Vibrating noise started, then a few days later the smell of gas, and now yes the Engine light is on. This has been on going for about 3 weeks.

My 2021 GMC Acadia steering wheel dangerously stiffened while I was turning off the road into a busy shopping parking lot making it difficult to continue my turn. Having to put on my brakes sharply as to not collide with the out going traffic. There was no warning prior to the incident and had to make a quick safety judgement call and hoped the steering wheel would turn. Only after does the warning come on saying there is an issue with the steering assist and to drive carefully! The following morning I took it to Eagle Buick/GMC. There the tech experienced the same. I was told the parts for the repair would take around a week with an estimated cost of $1604.25. I had to carefully drive back with traffic and unable to continue my days work. As I look up this issue I am finding other GMC vehicles with the same dangerous issues that should not wait until it causes an accident, injury or even death. Please make this an important priority as the occurrence has no warning and after it gives only a drive carefully?

My 2021 GMC Acadia that has 63,768 miles on it was idling Wednesday 9/30 when it died and would not start back we had to have it towed to a shop to get it checked out and it was throwing the P023F code for the fuel pump control module that has a recall bulletin for the same thing make model problem and under their 80,000 miles but recall not on my vin number and GM is refusing to pay for it. It's going to cost me 937.27 to get it fixed.

While driving home from work the car displayed a "No Fuel" warning, despite having a full tank of gas. Within seconds of the display showing the car stalled out and stopped right in the middle of the road. It would not go into neutral and I had to be towed from the middle of the road to a mechanic close by. Upon reading forums online it looks like this is a known and common issue affecting the fuel pump sensor and system in these models. There are no open recalls but being this is known and happens so often I am shocked GMC has not taken ownership to recall and correct this issue. If I had not been on a slower road I could have gotten into an accident and, as I said, the car would not go in neutral so I couldn't even safely get off the road.

On 9/08/2026 I was driving and almost got a wreck but I was able to get out and was going less the 25 and lost control of the vehicle and barely hit the curb and the two air bags went off and I was sent to the hospital

While driving the brake vacuum pump exploded leading to catastrophic brake failure. My husband was driving and was able to stand on the brakes to get the car to stop, but had i been driving, I am not strong enough to have stopped the car. I have 3 children with my youngest being 1. If this had happened with me and my kids, we could have had a major wreck and/or DIED! GM is aware of the brake vacuum pump issues but does not have a recall on the part. The braske assist light did not come on the dash until brakes were lost.

No incident but steering assisted reduced could cause an issue. Also the fix is to reset the computer by detaching the negative pole on the battery. This could be an issue due to the heat in the car someone could get burned.

I have seen numerous complaints for this same issue. My 2021 Acadia with 31,600 miles failed to start when parked in garage. It turned over just fine but wouldn't fire as if it wasn't getting any fuel. I had it towed to my regular mechanic. He troubleshot it and told me it was the "Fuel Pump Power Control Module". He said he could replace it but it would have to be programmed by a GM dealer as he didn't have the equipment to do that. So I had it towed to the local GMC dealer. Two tow bills equal $360. There is a recall for this issue. It is called "Emission Recall N252516900, Fuel Pump Power Control Module". part number 13554820 I have yet to receive a recall notice. I have seen mentioned in several of the other complaints that I have read that many of the service employees say that this has been an ongoing issue for several of the GM vehicles. Hopefully I will get a recall notice soon and be able to get reimbursed for the cost of the repair.

My brake pedal got stiff when I was driving. I had zero control of my brakes. I was informed by a GMC dealership that my BRAKE BOOSTER blew up causing my brakes to stop working and metal shrapnel to be sent into my engine. My 2021 vehicle is a complete loss. GMC has done NOTHING to help me.
