problem #1

Jun 282012

Grand Cherokee 6-cyl

  • 36,700 miles
Engine started running roughly and attempted to stall in traffic. Check engine light came on. I went to Jeep dealer in gulf shores Alabama and was told that the left cylinder head was defective. I was also advised that it was a manufacturing defect that could result in catastrophic engine failure. It is a well known defect in the 2012 Cherokee with the 3.6 pentastar engine. If this vehicle had stalled while on an interstate ramp, or a valve in the defective head dropped down into the cylinder, an accident could result. Jeep has full knowledge of this defect but has not issued a recall. This could be as serious as the GM ignition switch issue.
