Engine Shut Off Without Warning problems of the 2009 Jeep Liberty

While driving 55 mph down a busy road, my Liberty's engine shut down without warning. No warning lights lit up on the dash, oil was full, and it was running great just before the failure. Upon inspection at a Chrysler dealer it was determined that the #5 valve failed causing the engine to seize immediately. Cost to replace the engine was $6971. 00. Chrysler nor mopar will admit that there is a problem with these engines, yet there was nothing I could have done to prevent the engine from seizing at 81,152 miles. Luckily I was able to get it off the road and stopped before I was hit by another vehicle. Liberty was 1, 152 miles over the power train warranty.
