The official notice
Defect
On certain vehicles equipped with a 2.5-L 4-cylinder engine, the engine block may be porous. As a result, the engine block could crack and cause internal or external coolant leaks. This could cause engine overheating or internal engine damage and result in an engine failure. For non-hybrid vehicles, this could also result in a sudden loss of engine power while driving. Note: This problem may lead to engine noise, smoke, cause warning lights to turn on and/or cause an audible chime to sound before an engine failure.
Safety Risk
A sudden loss of engine power could increase the risk of a crash. Additionally, an engine failure could create the risk of a fire.
Remedy
The company will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the engine block casting serial number. If the serial number is within the identified range, the dealer will replace the engine with a new one.
