One problem related to automatic transmission torque converter has been reported for the 2017 Chevrolet Suburban. The most recently reported issues are listed below.
While driving normally on the highway there appeared to be a hard shift between first and second gear and when second gear did kick in, there was a sudden jerk. Already having made an appointment with the dealership the next day, that morning a whirling sound appeared each time the acceleration pedal was pressed. When we got the vehicle to the dealership, they ran a diagnostic and it came back clear. I also pay for on star, and they provide me with regular diagnostic reports, which never indicated a problem and the check engine light never came on. The vehicle appeared fine on paper but with a test run, the dealership was able to see the problem and told us we needed a new transmission. A mechanic took our old transmission apart and said there was a problem with the torque converter and when it went up it sent shrapnel into the pumps and destroyed the transmission. This seems to be a common problem with certain gm trucks.
