Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The engine cylinder head was cracked between number three and four cylinders for a undetermined amount of time. Jeep would not confirm that a updated cylinder was made to fix the issue. I was told that Jeep had no records of cylinder heads cracking. A replacement head has been installed but the oil pressure is low due to the excessive bearing wear cause by coolant in the oil.”

“The engine has released more than one gallon of antifreeze into the oiling system in less than 500 miles. After removal of the valve cover, a fracture in the cooling system cylinder head water jacket has been found between cylinders 3 and 4 that permits coolant to enter into the oiling system. The dealership stated that the cylinder heads are known to crack without cause, can be replaced with a cylinder head that maybe prone to cracking again and in addition will require several more components to be replaced. The dealership offered no further information.”
