Front Seat Recliner problems of the 2017 Jeep Wrangler

At about 4,433 miles, my passenger complained that the front passenger seat would not recline. I inspected both driver and passenger front recliners, and found broken plastic pieces underneath both the driver and passenger inboard recliners. The dealership inspected and replaced both driver and passenger seatbacks. At about 8,052 miles, the passenger seat inboard recliner failed again. The dealership inspected and replaced the passenger seatback. At about 20,000 miles, the driver inboard recliner failed again. To date, the dealership has not replaced the fourth failed recliner. I have provided fca written notice of these failures. Since four seat recliners have failed within the first 20,000 miles, I am concerned that a design, material, or workmanship defect exists. I am also very concerned how these failed seat recliners will perform in a crash. Upon research, it appears that others have had multiple failures with these specific model year seat recliners as well. See NHTSA id number 11074326.
