My vehicle's transmission is lagging. It sometimes won't go when in drive and given gas. The engine will rev up but won't move. It shifts hard as well. The shift to park indicator comes on when the vehicle is in park and not moving. The radio screen sometimes won't turn off or on, like it's froze. When I turn the vehicle off and all power is off, I can walk in the house and about 4 minutes later my radio comes on by itself. Even if the radio is powered off. The volume will only go up to 32-36, as far as sound, while the radio screen shows 63. It's not loud at all! when I turn the volume button down, the radio increases volume but still isn't as loud as before. It has less than 30,000 miles on it and it's very upsetting. I've already had to put in the shop to replace one faulty part already.

In early April 2019, approximately the first week of April, I was driving the Traverse on a hill and stopped at a stop light. When the light turned green, I attempted to step on the gas and pull forward, but the car rolled backwards. I looked down to see if I was in reverse, but the car was in drive. This specific incident occurred a total of two times. On April 23, 2019 around 9:40 am I was driving and my car stalled multiple times during this trip. I was not sure if the car was going to make it to my final destination. The check engine light illuminated. On April 24, I received a call from the dealership. The dealership informed me that the car showed 4 'codes'. P0011 'a' camshaft position ' timing over-advanced or system performance bank 1 P0014 'B' camshaft position ' timing over-advanced or system performance bank 1 P0021 'a' camshaft position ' timing over-advanced or system performance bank 2 P0024 'B' camshaft position ' timing over-advanced or system performance bank 2 these codes represented a software problem related to the engine. Tim informed me that according to the GM bulletin (pip5568E or document id# 5251270), the recommendation is to delete the codes and that there is not a software solution to the problem at this time. The dealership informed me that because of the severity of the symptoms I was experiencing related to the codes he did not feel comfortable with the recommendation from the GM bulletin and he would be escalating the issue to the GM district manager. The ultimate result is that they want to delete the codes and have me come pick up the car as there is no solution to the issue at this time.

On a normal sunny afternoon after about driving for 20 or so miles, we were approaching a red light in a line of traffic at a busy intersection, the vehicle appeared to start slightly jerking as I was coming to a stop. Once stopped the stop/start function operated. Upon releasing the brake to accelerate thru the intersection the vehicle started jerking and lurching uncontrollably then shut down completely, the instrument panel went dark. I could not get the car out of the line of heavy traffic, I had to put it in park right in the middle of the road and try the start button. Thankfully the vehicle started, the check engine light came on and stayed on but the vehicle appeared to be running normal again and we were able to proceed. This was very upsetting and dangerous as it occurred in heavy traffic at an intersection. I took it back to the dealership the next day (I bought this vehicle used 2 weeks prior, this was only my 2nd time driving it and I had only put 70 miles on it in the 2 weeks I had it). The current mileage is approx. 25,600. The hard code the dealer retrieved noted a camshaft sensor issue. The sensor was notreplaced, I was told that GM is aware of this problem and would be issuing a recall but they are not sure when. They said it was a computer program issue. I am very concerned for our safety while operating this vehicle as they said the issue may or may not happen again. Onstar sent me an email notifying me that my 2018 chev Traverse had and engine/transmission issue and to take it to the dealer asap. Thank you onstar, I am very aware of the issue and it was already at the dealer but I appreciate that you also recognize that there was a problem. Hoping GM does something very soon, this is a $50,000 vehicle with only 25K miles on it and it is not safe to operate under these conditions.

Vehicle turned off during operation. Vehicle was traveling at 45 mph on a local highway and turned off. Coasted the vehicle into an empty parking lot where parking gear was applied and vehicle was restarted. Check engine light was now present. Vehicle was dropped off at dealership where it was purchased. Was informed it was a software anomaly and is currently being investigated. No repair, software was reset and vehicle was released

On 2 separate occasions, one while on a highway going around 65 mph. The other occasion was while going around 45-65 mph on a city road. The display screen in front of the driver flashed on and off for around 10-20 minutes. While the screen was flashing on and off, the buttons on the steering wheel would not change any of the menu screens. I took the vehicle back to the dealer and they informed me that because it was a soft code and not a hard code, they would not do anything.

While driving car on a state highway, it began to jerk, lose power and check engine light came on. Next day taken in to dealer, informed GM is aware of the problem that also affects several other GM cars and is unable to fix.

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.

After getting the recall done on the back up camera done. At jim glover on the river in tulsa I continued having issues with camera took it back as the phone charger was also having problems now and the camera wasn't fixed. Took it back said they didn't follow all the instructions for the recall and now it's fixed. One agent said they rebooted the phone charger when I picked it up the other told me they did nothing as the was no problem with it. About a few weeks later the car alarm starts going off randomly with it St or not set and the driver mirrors doors not defrost. Again I got the oh nothing is wrong with it it is fine hey still alarm goes off with our with out alarm set.

Purchased a 2018 Chevrolet Traverse in October. Beginning within the first 30 days the car made a loud roaring noise when @ 2100 RPM and going approximately 74 mph. Just thought it was a fluke. Then starting in December, while travelling out of town, it persisted every time we drove it. It also would lose power or something strange when putting it in gear after backing out of our driveway. We would accelerate for a short distance when the RPM's would rev-up to 6-7,000 RPM but the car wouldn't go. It was almost as if it would slip itself into neutral while going down the road. We have taken the car in 4 different times for repair and the problem has not been fixed. The car also turns itself off. The panel goes black. When we start hearing a loud rumbling noise while sitting in neutral at a fast food drive thru or red light we turn the air conditioning off to try and hear the noise better and the car dies and the panel goes black. We have had to actually re-start the car. We are extremely concerned for the safety of this vehicle and are returning it do the dealership tomorrow for our final time. They have been given numerous opportunities to repair the problem and things are actually getting worse. This is such a shame because we were so excited about our new car. We live on a very busy road where vehicles and 18 wheelers can go in excess of 70 miles an hour and I am afraid to pull out of my driveway with this car. We have even coasted to the side of the road when it looses power to avoid being hit from behind. The dealership wouldn't even start repairs until they could duplicate the problem. Finally a mechanic road with us and witnessed the noise but they have not been able to "duplicate" the slipping out of gear type problems. Since it is happening regularly now, maybe then can see for themselves. It has truly become a serious safety problem.
