One problem related to battery cable has been reported for the 2015 Chevrolet Suburban. The most recently reported issues are listed below.
Vehicle was serviced at the local Chevrolet dealership subject to NHTSA recall 18v-586 on Friday, September 14, 2018. The next day, 9/15/18, vehicle experienced same problems that were happening prior to being serviced. Specifically, on Saturday(9/15) at approx. 4:30 p. M. Cst, while making a rolling right hand turn on green the vehicle lost power steering and lost all power. No one was directly behind me as I stopped in the middle of the city street. I put on the flashers and, after unsuccessfully trying to restart the vehicle in neutral, was able to restart the car while in park. I noticed the battery voltage meter was lower than normal for the remainder of my trip, however, it had returned to normal the next morning. This has been an ongoing problem which started on Aug. 9, 2018. First trip to the chevy dealership resulted in replacing the f-module. Problems persisted and the next recommendation was to replace the negative battery cable, which was done on 9/10/18. Now, after servicing due to recall, I continue to have the same problem.
