2021 GMC Acadia problems

“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.”

“Car was running great and mins later I get an error stating steering assist is reduced -Drive with care. Vehicles temperature gauge is stuck at cold and fans turn on after turning off the vehicle. I had the vehicle serviced at Dave White on Alexis Rd in Sylvania almost exactly a year ago for the same reason. Was told by the service manager the issue was a computer update and not the thermostat and proceeded to charge for the "update" no issues with vehicle until now.”

“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?”

“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.”

“This is a very known issue that has been reoccurring with GMC Acadia. The torque converter slipping. That cost alone is over $7.000 for the transmission. I am still making monthly payments for my 2021 Acadia. With rising cost above the board GMC could have resolved this issue before releasing this vehicle to the public for purchase. Only had this vehicle for 2 years and already a new transmission is needed. Other individuals i personally know have the same issue. From my research GMC is aware and fails to do a recall on this issue.”
