Have had the rear door locks stop working during the cold, it would not allow the doors to shut and stay shut. I did have children in car seats in the truck at the time. After trying to get the locks to work for about 10 minutes they stared working again. Also have an oil leak that was discovered while having an oil change. I became aware of Technical Service Bulletin: 23/2083, NHTSA ID Number: 10233594 (Engine and Engine Cooling) and related the failure to the TSB. Called the dealership and they said they couldn’t do anything about it because there was no recall for it. My truck is included in the vehicles from the Kansas and Detroit plants that are affected by a defective oil pan. The manufacturer is refusing to issue a recall.
