Trailer brakes keep disconnecting and connecting . Warning pops up on dash to check trailer connections. I may not happen for a hundred miles or does it 10 or 12 times in just a few miles.I've seen several complaints from on line reports but no solutions from GM yet. Very frustrating when trying to pull a trailer.

While driving on the highway our transmission cooling line completely separated at rubber hose to metal line crimp. This cause transmission fluid to burst out all over the vehicle including the windshield and trailer. Vehicle immediately stopped pulling and we barely were able to get to the side of the road. This also caused a catastrophic transmission failure costing approximately $10,000 to repair. GM covered some of the transmission cost but still left us with $5000 bill for a transmission line defect on a vehicle under 100,000 miles. This created a unsafe condition with the trans fluid on the windshield and immediate loss of drive. All maintenance was performed per manufacturers…

My vehicle was taken to Legacy Chevrolet of Waxahachie where a routine recall notice was addressed. During the process they technician broke my battery terminal. Upon my discovery the dealership claimed the broken terminal must have just broke on its own during the time it was at their dealership in spite of the ECM module update requiring the technician to specifically remove the battery cable from that specific terminal. Legacy has refused to address this issue and charged me for the new batteries as well as for the tow that was required. The damage was caused by their technician and all of the costs incurred should have been absorbed by the dealership.
