general problems of the 2015 GMC Sierra 3500

The contact owns a 2015 GMC Sierra 3500. The contact stated her husband was driving at 20-30 mph and hauling a trailer, the driver entered the highway, made a right turn and the vehicle loss of power steering assist and became difficult to steer. The vehicle was towed to cavender Buick GMC west (7400 TX-1604 loop, san antonio, TX 78254) to be diagnosed. The driver was informed that the power steering needed to be replaced. The vehicle was not repaired. The contact referenced the failure to (NHTSA campaign number: 14v719000 (steering) however the VIN was not included. The manufacturer was not made aware of the failure. The failure mileage was 33,000.

Front tires are continually wearing on the front outside edge. Wearing until bald in first 15000 miles of ownership, multiple front end alignment calibration tests and actual front end calibration not resolving issue. Front tires replaced at approximately 23,000 miles and again wearing on outside edge at 40,000 miles. Worse on driver side. Contacted dealer several times for resolution and contacted gm twice to open ticket. Last gm ticket was 8-4030406653. Tires are michelin and are supposed to last 65,000 miles. Never seen this type of wear on any past gm vehicle owned. Rear tires are in excellent condition. Unable to get dealer or gm to find cause and resolve once and for all. Tired of paying out of pocket alignment costs. The front tires are on the second set and the current vehicle mileage is 42k. I have attached images of front driver side tire which has greatest wear and image 20180328_113012. Jpg is the original back tires which have no wear. Front are the second set since purchasing vehicle. Original set was completely bald on outside edge before 19k miles.
