Example complaints
One per model year, chosen for length and detail. Personal details are removed. They are consumer reports, not findings.
2015: “While driving, the power steering hose came off causing a sudden lose of fluid resulting in loss of power steering and power brakes. Although a recall/bulletin was to be issued on this per the dealer (I can not find evidence of a recall for this), my vehicle was built after the incident was recognized and thought to be corrected. Sudden lose of power steering and power brakes in a vehicle this size while pulling a large trailer could have been disastrous.”
