While driving in the far right lane my dashboard went completely black, the radio went off and my steering wheel was extremely difficult to turn.I was able to maneuver the car to sidewalk the car was still in drive the keys were in ignition. I turned the key and attempted to restart the car it made a terrible banging clunking noise.I called the dealer and told them waited 15 minutes later the car started.ths really needs to be investigated as I could have caused are been involved in a accident. I'm very afraid to drive my car. I took the car in later to dealer they kept it until Friday provided me a loaner they claimed they drove it and it didn't act up. But its not like they drove it all day I'm extremely upset and disappointed in this matter. I feel they discounted what I said.this could occur while a teenager are elderly person is driving. Please please look into this matter.

At times, the vehicle jerks while shifting. I have experienced heavy jolting, rough shifting, especially during low speeds. While on highway or during strong acceleration, car shifts great. Mostly the issues are during downshifts or low speed shifts. Took to Chevrolet dealership, was told a factory reset may help adjust to driving styles. We bought car used with 35000 miles. This did not help. Not even sure if this is an option. No check engine lights or anything. Dealership cannot locate problem. Says transmission takes some getting used to. Awesome car, just wish this problem was corrected.

At speeds 15 mph and above after decelerating then accelerating transmission will make a noise ranging from a clink, clank, clunk to a banging jolt as if the car has been rear ended. The more pressure on acceleration and the lower the gear the louder the noise and the greater the jolt. Dealership states transmission is operating properly.
