Car Stall problems of the 2018 Chevrolet Traverse

I have had issues with my 2018 Traverse since December. The problem started around 9,000 miles. I took my vehicle into the dealership and they could not duplicate the issue. I would put the vehicle in drive and the "d" light would blink but the car would not move. In March after several trips to the dealership they finally repaired the vehicle. They removed the transmission and replaced a sensor. The vehicle did not have any issues until July 23rd when driving on a city road the car got stuck in first gear. I was pushing the gas pedal and the car would not go over 20 mph. I took the vehicle in and they replaced the tcm and solenoid sensor. I picked up the vehicle on 8/8 only to return on 8/15 when the car stalled and jerked while I was driving. On 8/16 I spoke with the dealership who informed me Chevrolet advised them to clear the code and return the vehicle to me. This is a known issue to them and the engineering department is working on figuring out the problem. As of 8/18/2019 this vehicle has spent 47 days in the shop for repairs and has 10 repair orders.

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.

Car had about 10000 miles and in two separate occasions has stalled, steering wheel had stop working, couldn't steer, car turns off when stopped at traffic lights, alrms go off and dealer just says they can only reprogram the computer, no repairs available. On a third time braking system alarms went off and dealer had to replace the braking system. Vehicle has always failed while in motion. Dealer and manufacturer will be responsible if someone gets hurt because this car does not function as it should.

Transmission light came on, car started excessively jerking and stalling (vehicle was in motion on a city street while turning and driving straight) took into dealership and said gm does not have a �fix� for this problem and it's currently under investigation. There are �concerns with all 4 or pairs of camshaft position system performance dcts p0011 p0014 p0021 and p0024. Dealership cleared codes and we were told �chances are it won't happen again�.
