Check Engine Light On problems of the 2018 Chevrolet Traverse

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.

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.

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.

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.

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.
