When I drive my car after coming out of reverse the car revs up between 35 and 45 rpms. This is when it is going about 25 mph. When I remove my foot from the gas the car jerks violently forward and rpms drop to 25rms. When I give it some gas the rpms go up again to the 35-45 RPM. The only way to get this to stop is to pull over, put the car in park, turn off the car and open the door. I let it sit for about 10 min and then turn it back on and drive. I have brought it to the dealer several times and they keep telling me there is nothing wrong that when they plug it in everything comes back fine. I have had other people in the car and it has happened with witnesses so I am not imagining it. This is a brand new vehicle and started happening a few days after I got it. The date I am giving of when it happened is the latest one - it started 8/18.

My vehicle has been making a noise every since the day of purchase. It started as a vague sound and has since gotten worse. The noise is coming from the rear exhaust. At certain speeds of travel the noise gets worse. I have done a visibility check of the rear exhaust pipe and noticed the assembled exhaust where it was welded is loose and shaking. I'm not for sure if this is where the noise is coming from but it could use some investigation. I purchased my vehicle with no mileage about 5 months ago from hennessy GMC in morrow Georgia.

1. lane departure warning only works with hands off the steering wheel.GM refuses to fix it as they said they designed the vehicle this way. Who in their right mind drives with hands off the steering wheel, we bought this feature for our young drivers to have them reminded if they drift out of their lane. 2. warning window about distracted driving displays on the radio screen while driving, so you have to take your eyes off the road to push ok to get rid of it. GM refuses to do anything about that either. 3. seatbelts are non adjustable heightwise and lengthwise. They are ok for tall people, for me being 5'4 they are uncomfortable and rub my neck.so I have to drive without them. GM in 2018 designed all their GMC and Buick vehicles this way, to save money, I am sure. These type of unadjustsble seatbelts were used back im the 80's.

Their is a start/stop feature in this model where the car automatically shuts off when the vehicle starts. I'm told it's for fuel efficiency. One day I stopped at a stop sign which happened to be on a small hill. The car stopped and began rolling backwards. It scared me and I thought I would hit the car behind me. I immediately took my foot off the brake to make the car re-start, then immediately stepped on the brake. I don't think we should sacrifice safety over fuel. If only there was an option to disable this function. I was scared for the people who were behind me. Scary situation to be in!

There is no way to deactivate the auto / stop feature; I consider each user should have the option to activate or deactivate this option.

Purchased a brand new GMC Terrain. 12 days and 460 miles later the service engine soon light came on. Took it to dealership for a P050F. This is code for a leak in the booster. They did not repair anything, just checked for leak and reset engine light. As I read more, the problem affects the brakes ability to function properly increasing danger to driver. There is also defective stop/idle on the engine that no longer works. I was just driving down the road in town when it popped on. GM and young's have refused to refund this defective vehicle.

The weather was dry with a overcast sky. The traffic was very light.it was not possible for any foreign matter to hit the glass.I ammediately drove the vehicle to the GMC, where I purchased it.( dixie Buick GMC).my vehicle only has 2040 miles on it.this was a Saturday and the service dept. Was closed. Spoke to the sales manager, who said he never seen anything like this before. He gave me a loaner car to use. The service dept. Called on Monday, and stated that the was no defect, and I or my insurance co, would have to pay. I called GMC customer support and they stated that they would do what the service dept. Said.so they will not cover it.finally today I called my insurance co. And looks like they also will not cover it.I'am still waiting for a final decision from state farm ins.my vehicle was traveling South on interstate 75 in South West Florida in ft. Myers.
