This Jeep had the 4. 7l v8 engine. Jeep was running fine, never had any issues with leaking fluids, etc. Or any engine issues at all. Went to a friends house for a couple hours and when I went to leave, the vehicle started very rough and had no power - hitting the brake to change gears would stall the engine. Diagnostic testing showed no compression in the first cylinder. I was unable to pay to have my engine torn apart (keep in mind I only had this vehicle for little over a year and still owed over $1000 on something that was not driveable), but from the symptoms it seems this was caused by a dropped valve seat. I have seen numerous complaints on this issue in this engine (in Jeeps and other Chrysler vehicles) and am surprised that no recall has been made. I am unsure what would have happened if I was driving at 50 mph when the engine failed.
Dt consumer stated the engine failed on September 16, 2005, the oil pressure dropped to zero while on a hill, all types of noise came out of the engine. Consumer stated they had the vehicle towed to a dealer, and dealer said there was sludge build up inside the motor. Consumer a has used the proper oil as stated in the owners manual. Consumer contacted the manufacturer, they said there was nothing they could do. They claimed it was not from changing the oil at Chrysler. However, consumer stated they had records for the oil changes at their local mechanic.
I was driving on interstate 68 in maryland when engine failed. Douglas motors a member of the Chrysler group informs me the engine failed due to sludge. Engine oil has been changed every 3000 to 5000 miles with 5w 30. Chrysler offers no help except I should of taken the extends warranty.
While driving at 65 mph engine failed. As a result, power steering and brakes malfunctioned. Took vehicle to mechanic but they couldn't find anything wrong. Two hundred miles later, the same thing, nothing was found. At 6133 miles it happened again. Consumer took vehicle to another mechanic. Three different mechanics and no one could find anything. Problem still exist.
