Driving late at night with family down a state highway/city street with some stoplights and rotary, vehicle suddenly seems to be intermittently losing power or transmission slipping when driving. When giving gas entering rotary, intermittent slipping/power loss (like a skipping power/slipping transmission) worsened - felt greater loss of power and for slightly longer periods. Noted engine light came on. Worsening intermittent power failure/slipping/hesitation/jerking continued when giving gas to engine for ~1/4 mile until pulled into shopping mall parking lot. Felt lucky to be able to reach lot, called for flatbed tow to dealer. Dealer had vehicle for 1 week, and when assessment complete, reported dtc P0011, P0014, P0021 and P0024 cam codes. They visually inspected with no concerns, test actuator system operating. Search for bulletins revealed document 5251270 with no repair yet for anomaly, which describes "some customers may comment that the ses [service engine soon] lamp is illuminated. This lamp may have come on by itself or in some cases, the customer may experience drivability issues such as a stall, lurch, stumble, hesitation or power loss after an auto stop/restart." Notes technician may find the above listed codes. Cause is listed as "a software anomaly that allows the 'verify sync' status to not restart and reach full 'sync' when the engine restarts. The ECM then reports actual cam positions as '0' while it continues to command the actuators to move resulting in engine roughness and/or drivability concerns (as stated above) with the possibility of setting multiple cam phaser performance dtcs." Instructions on the bulletin are to check and clear codes and return vehicle to customer. Bulletin created on 5/7/2018 with 5 updates since. Brought vehicle back to dealer due to concerns of lack of fix and safety when recurs, dealer unable to replicate.

I had stopped for a red light on a city street. The auto stop was on (stops the engine idling) and when I attempted to go after the light turned green, I would press the accelerator and the car would lurch forward, then do nothing, lurch forward, then nothing and the engine light came on. I got it into the nearest parking lot and turned it off. I restarted the car, the engine light remained on and then I had the car towed to the local Chevrolet dealership. The dealership looked at the car, said it was a "known issue" in cars of this make and model year, but they didn't have a fix for it yet. They told me they cleared the error codes and to keep driving it and let them know when it happened again. I said I was concerned about it doing again and me possibly being hit by someone who expected my car to move and the dealership said my other choice was not to drive it until the software fix was available; however, they could provide no timeframe on when or if a fix would be available.

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.

As I was waiting at a red light and proceeded to to turn green I pressed on the gas to accelerated and the vechicle began to jerk and lerch forward and would not advance almost as as it was losing power or not respoding to the gas pedal. Very scary in the middle of an intersection. I have taken my SUV in several times now for the same issue and have been told there is now repair yet issued by GM. I purchased my car in Sept 2018 and started having issued just months after. This is scary and unsafe.

While driving my Traverse today the vehicle suddenly jerked to a stop while driving through a restaurant parking lot twice, then while attempted to accelerate to the suicide lane on a 4 lane road the check engine light came on and the engine began to over rev red lining as if it couldn't change gears. This could have caused a serious accident and certainly should not be happening on an automatic vehicle with 16,000 miles on it. On arrival at dealership I inquired if this was a known issue and was informed they had two of the same year model and make cars that had repairs completed due to a strikingly similar issue. I'm requesting this be reviewed or investigated as there are also reports on forums across the internet of other 2018 Chevrolet Traverse drivers experiencing this issue between 10,000 and 20,000 miles meaning it may be a larger scale issue the consumers are facing and the manufacturer is putting us at undo risk by not issuing a recall or notice regarding this known issue. Not to mention many of us spent $45,000 or more for these vehicles and should not be having these issues. Thank you for any help you can provide.

While driving on flat level surface the vehicle would sporadically shift into first gear. I pulled over shut off the vehicle and it corrected itself. The next day after putting it into drive it wouldn't shift out of 1st. I tried putting it in L and manually shifting and it still wouldn't leave 1st. This is a direct safety issue as it does this while driving. It jerks the vehicle and if an inexperienced driver experiences this it will be fatal.

Sporadic transmission failure during operation of vehicle. During operation of vehicle a sudden jerk of the transmission occurs and the vehicle is unable to shift gears in transit. I am force to pull over and stop vehicle in order to procedure. This has occurred 3 times in the past 7 months. Dealer has informed me that GM reported they are unable to repair this problem at this time.

- The Villages, FL, USA

On freeway at 75mph with cruise control on, every time it goes uphill there is a constant surging feel like it wants to shift from 8th to 9th gear but it doesn't shift down and keeps surging. I suspect a transmission problem or something related to the computers and how they determine when to shift with cruise control on.

When placing the vehicle into drive, on numerous occasions, the vehicle would act as if the transmission was in neutral. The drive "D" indicator on the dashboard would flash. After a few seconds, the transmission would engage and on more then 1 occasion, the car jerked forward. Some occasions I would have to place the vehicle back into park and then back to drive for the transmission to engage properly. Took vehicle back to dealer around a dozen times trying to replicate the issue with no luck. Dealer believes they know what the issue is, but could not find any hard codes with the obd2 to get authorization to make repairs.

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.

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.

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.

I purchased a 2018 Traverse/redline on 6 Feb 2018, drove it less than 100 miles, and the transmission stopped working two (2) days later. The vehicle was towed back to the dealer. The service section advised they don't have the equipment needed to diagnose the problem, and that the equipment is expected sometime next week. Today, 20 Feb 2018, still awaiting equipment. I told the dealership mgr that I don't want that vehicle back. The mgr said that his hands are tied and I would have to deal with GM. Contacted GM on 9 Feb, and completed an application for what I was let to believe was a 'buy back' of my vehicle. The GM rep informed me that someone would contact me within two days. Needless to say, it didn't happen. I called GM back on 13 Feb, spoke with another rep who had no clue as to why I was calling. This rep asked for 72 hours, and would get back to me. On 20 Feb, I rcvd a call from the GM rep who stated that GM can only do a buy back after 3 or more problems with the vehicle. Bottom line is that I bought a 46,000 dollar piece of junk, and of course, no one wants it back. And GM is more than aware this problem exists... thank god I wasn't making a turn in front of another vehicle when the vehicle stalled... truly an unsafe vehicle... buyer beware !
