While at a traffic light, the engine auto stop engaged as usual. However, upon releasing the brake to proceed through the intersection, the vehicle restarted but would not run properly. The vehicle would lurch/jerk forward then lose power over and over again. It felt like we would get whiplashed from the movement of the vehicle. The engine light came on. We were able to make it off of the road into a parking lot in order to call the dealership for advice. They advised to turn the vehicle off and restart it in order to reset the systems. While this restored the ability to drive the vehicle, the check engine light has remained on and the vehicle will be going into the dealership in 3 days (the earliest available appointment) to be evaluated.

Started SUV then noticed check engine came on once driving. Went down a major road and noticed the SUV was losing power and wasn't shifting properly. Had my kids in the car and was able to turn around to get back to my house. Once I got it to a safe spot I pressed on the gas to properly park it. Then the SUV jerked forward in a sudden amd hard fashion and I almost hit the car in front of me.

While driving on rainy day about 20 mph the engine would alternate between a power surge to no power. This continued for several minutes while driving (nowhere to pull over) until the engine completely died. Both the jerking forward and the shutoff while driving could have caused a horrible accident but fortunately we were lucky. The street was a city street, it was a very wet environment, and I was going straight. Traffic was stop and go so the car speed never was higher than about 20mph. All events occurred while SUV was in motion. Engine light was on. Took car in for service. They said nothing is currently a reported issue during the dtc status check but there was a "history" of "lin bus 14 lost communication with device", and a few reports regarding intake camshaft and exhaust camshaft issues. Have not heard the dealer's assessment yet.

My wife was driving to a college interview from rio grande city tx to austin tx; while she was passing by pleasantown tx, the SUV reduced the speed by itself and she could not get it up passing 25 miles per hour. It seemed like a transmission issue. She was towed to the nearest Chevrolet dealer and is still there.

New lease under 8,000 miles and the transmission failed. While stopped at a red light on a heavily trafficked roadway, when I hi the gas there was a loud grinding. The transmission would not engage again as I sat in the middle of main roadway with car speeding by as my wife, my children and my niece sat in the vehicle with me. After trying to get the transmission to engage in "AWD" I was able to get the car off the roadway and into a much safer parking area. When put into "park" the car continued to roll unless the "emergency brake was engaged. The car is currently in a dealer in Maryland awaiting repairs more than a week later, and I am back at home on long island.

At 7,256 miles, the engine light came on. Dale willey automotive replaced the engine coolant fan motor & assembly, as it was intermittently turning on & off, causing a code to be fired for the engine light. The radiator also had to be replaced due to a leak. Also, a fuse had to be replaced that was installed incorrectly by the factory with a plastic coating covering the metal contact of the fuse which was causing intermittent power.

Was driving from nyc to toronto. We stopped 3 hours after for bathroom break and lunch. I did not leave the car therefore the car remained on. Drove for another 2 hours and stopped for a bathroom break at junius ponds travel plaza around 330pm. Turned off the car and thats when we realized we drove without the key. This is in the middle of winter with children in the car. We called onstar and Chevy but they could not assist in anyway. My parents had to drive to us to give us they key. It took them over 6 hours because it was rush hour. Imagine 6 hours being stranded with kids. Luckily we were at a rest stop with food, bathroom and most importantly heat. It turned out while my husband was busy packing up the car, he had switched into his winter jacket leaving his sweatshirt behind which that keys were in. The car was in park in our driveway. We drove off and there were no notifications. We even stopped at startbucks and put the car in park again. This is a major safety issue as this will make it easy for theft and risks the safety and health of the people in the car. Can you imagine if we had stopped at a place that did not have heat. Onstar only allows 2 remote engine start then it will tell you that the car engine has to be manually turned on before using the remote start again. Im not talking about if a child accidentally throws the keys out the window in the middle of the highway and the car should turn off. Im suggesting that the car should not be allowed to move from parking if the key is not in the vehicle. Imagine driving 5 hours 300+ miles away from the key and no warning.
