Over the past month and a half I have been noticing that when I attempt to push the gas to make my car go faster that it doesn't accelerate. It is usually when my vehicle is already in motion and I attempt to go faster. I can hear it making a noise like it's trying to go faster but there is definitely a delay before the vehicle actually starts to go faster. Usually I am on a normal streets going anywhere from 35-55 mph (depending on the street and post speed limit), so it's not always a huge deal when it happens. I do a lot of highway driving and this is where my concern comes into play. A few weeks ago I was merging onto 696. There was more then enough room in the first lane for me to safely merge into traffic, however, when attempting to accelerate my vehicle it would not go above 35mph for a good 30 seconds and a car that was in the right lane probably going at least 70mph almost rear ended me. There was another instance when I was merging onto the vandyke expressway where the posted speed is 70mph and the exact same thing happened. Trying to merge into traffic with a post speed of 70mph and my vehicle not going above 35mph is not safe. My vehicle was recently in the shop because my air compressor literally melted and started smoking as I was driving my car. When it was in the shop this problem was mentioned to them and we were told "the problem would be like finding a needle in a haystack" the air compressor was fixed along with the current air bag recall, however, this acceleration issue was not addressed whatsoever. To me this is the most pressing issue and should have taken priority. I should be able to know that when I am merging onto a highway with fast moving traffic that my car is going to accelerate and not potentially cause a major accident.

My car skips as if the engine is not getting enough gas. I will be driving along and the Acadia will shake and do a little skip jump. It does this at least a couple of times a week. I also have to constantly add oil to the truck even when I am 1000 miles out from my next oil change.

While driving on interstate 17W going to deposit, NY, I suddenly saw an error message on the dashboard that read "service traction control", then it read "traction control off" and then the last thing that read was "engine power is reduced". that's when my car dropped from going 60 mph on cruise control to 20 mph and I could not accelerate. Thankfully, I was already in the right lane and was able to pull onto the shoulder. At that point, I turned off the vehicle and waited, thinking that the error message would go away and it's just a computer glitch, as this is common with this model vehicle. I started the vehicle again and it had full power but the error message to "service traction control" was still on and alternating between that message and "traction control off". this incident occurred three separate times on the same day along the same highway and at one of the times, there was a large vehicle behind me and thankfully, the driver was able to quickly move to the next lane because I the engine reduced power and I could not accelerate. I put my hazard lights on each time it happened. Thank god my children were not in the car with me when this happened. I have had many difficulties with this vehicle since it was first leased in 2011. I think that all the GMC Acadias should be recalled as it poses such a tremendous danger to motorists.
