Gutless Gas Hog
By TonyC on Tuesday, November 12, 2024
Make no mistake, this is a beautiful suv. We purchased a 2024 Acadia Denali in July of 2024....5100 miles and traded it in. Fuel economy never got better than 19 highway. I can live with that if I have some power but that was lacking as well. My 2021 F250 gets better mileage. Even when we traded it in, the salesman took it for a spin and commented on how gutless it was. 4700 miles took it back because of a stange noise. Front differential was leaking and slipping. Once fixed the fuel economy seemed to get worse...strange. the noise was gone but some of the similar issues still existed. This is probably the loudest inetrior noise car I have ever driven. The little 4 banger engine just cannot handle the weight of the car and is loud. The interior is beautiful but the position of the AC vents is bad. To cool where you sit you will.also freeze your kneecaps because your knees are right in front of the vent. The infotainment system could easily be about half the size. Kind of dumb to have something that big and bright shining in your face while driving at night. Yes, you can dim it but then you cannot see it during the daytime. We had high hopes for this car. My wife loved the color and style...outside of that, harsh reality was, this thing was a terrible choice. We took a $15k hit on trade in and I have to say...it was money well spent. - 3.0
All looks, no power
By jgerwig on Friday, August 23, 2024
This vehicle is beautiful inside and out, but beauty is skin deep. The pathetic 4 cylinder engine that GM decided to put in this large, heavy SUV was a huge mistake and disappointment. When you accelerate on the freeway, it whines so loud (like an old four banger) that you think it's going to explode. I also don't believe their claim of 328 hp; this thing is weak and certainly doesn't feel like is has that kind of horsepower. Overpriced and underpowered is not a combination I'm interested in. - 2.0
2 stars so far!
By Pipeweld on Wednesday, July 30, 2025
2025 Acadia Denali, this is the most disappointing vehicle purchase ever! 1158 Miles and the brakes go out! In the shop twice for over 45 days! Now the Infotainment system is going wacko! The remote start works, but won't work right! When you try and do it as manual says, it does nothing! Then you have to turn it off and start from inside! So much other glicthy stuff too! Run away!!!
