Transmission was shifting 'roughly' both in accelerating and decelerating conditions. So rough that movement within the vehicle was experienced by driver and passengers. When the vehicle was undergoing braking and decelerating conditions the vehicle would also make noise as shifts occurred in the transmission (loud banging or knocking sounds were heard). The vehicle was maintained according to manufacturers recommendation. Eventually the transmission experienced more unsafe conditions when gears would not engage during acceleration. The vehicle would roll backwards on inclined surfaces for several inches to several feet before transmission engagement. If traffic was behind on any incline the driver would have to use brake to prevent rolling backward and making impact with vehicle behind.

My condenser went out at 96K. I contacted GM and they stated that they had a recall on the condenser. Took the vehicle in to a GM/Chevrolet dealership and they began to inform me that the recall only is for vehicles less than 60K. They stated that GM knows there is a problem but due to mileage my vehicle is not covered. Due to living in the South I can not afford to have a car and not have air. So we fixed the condenser out of pocket. 1st-the condenser part was on a national back order and they stated that it could take up to a month to receive the part. Alert that there is a problem with the manufactory making condensers for GM cars. 2nd-the part was $200-300, although the service was $1100. 3rd-6 months after the replacement of the condenser and all working fine, paying out of pocket. The transmission goes out and the connection is associated with the replacement of the condenser. GM is aware of this issue but only wants to assist with people who mileage is less than 60K. There is obviously a serious problem and GM has not taken ownership! total cost in 2yrs for repairing and fixing 1part that lead to 3parts $4.5K.

Car would rev, then shift very hard into gear from a full stop - either going forward or into reverse. Had also noticed some uneven gear shifts when go up hills and revving of engine prior to transmission engaging when on the highway. Taken to dealership, where I was told the transmission pump went out and would require the entire transmission to be replaced, which was not under warranty. This happened at 144,400 miles. However, the remanufactured transmission would be waranteed for 300,000 miles.

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.

Vehicle is creating a buffeting, pressure sound and sensation at low to mid range speeds. Creating headache, dizziness and strain.

- Ellicott City, MD, USA

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.

- Hayward, CA, USA

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.
