We have multiple problems with our new Suburban. After traveling slowly or coasting in traffic, when I try to accelerate the vehicle won't go and when it finally decides to go it shudders and vibrates badly, it also does this from a complete stop, been to the dealer 2 times so far this and the last time they told me "it is a normal characteristic of vehicle". it is a very bad one and it will cause a wreck! the radio display flickers all the time even when back up camara is on, GM has no fix for this yet either! the vehicle sticker says it has heated/ac seats, it doesn't have A/C seats, they are airrated from the air in vehicle, that was a total misrepresentation of the product on the sales sticker. GM rep had us test drive another Suburban and we drove 3 different ones and not one of the others did the things our does. When we informed GM of this they said sorry we don't qualify for a buyback/replacement. GM doesn't care to help and its their very expensive product. I hope no one dies or is injured from the hesitations that GM know these vehicles have that is 0.7 seconds before the vehicle will engage or reengage when excelerating from a slow roll or a complete stop.

When driving the 2015 Suburban we experience an awful ear pressure and vibration. The car is not drivable and is causing headaches and vertigo. The problem is known by service techs and GM. They believe there is a problem when the car transitions from V8 to V4. There are multiple forums online regarding the issue. GM has not issued a fix as of yet. From what I have read, the problem is found in 2015 Suburban, escalades, and Yukon XLS. We purchased the vehicle with 1750 miles on it. After putting 500 miles on it, we cannot wait to get rid of it, and have attempted to initiate a buyback procedure with GM.

This vehicle has a push button start/stop. You can stop the vehicle while it is in gear, and if you get out the vehicle can just roll away. This has nearly caused 2 serious accidents, once it rolled backwards, narrowly missing a pedestrian, another time forwards into a car in front. GM need to rectify this asap.

The vehicle completely stalls and loses all power. It usually happens when you run the vehicle on the highway and have to come to a stop after exiting. In my case I drove the vehicle for an hour and half and exited the express way. Once, I exited and slowed down to come to a complete stop the engine starts to run rough and just before you completely stop it stalls out. This has happened at least sevne times on a 1400 mile trip. It even happens when you come to a stop behind other cars. You can put it in park or neutral and the vehicle will restart.
