	Rating	Comments
Engine		An occasional problem on this vehicle is the failure of the Timing Belt (2.4L engine only). This failure can cause the engine to stall and will prevent the engine from starting. When the timing belt fails it may also damage the Crankshaft Position (CKP) Sensor. The damaged CKP can prevent the engine from starting, and may cause the Check Engine Light to illuminate. In extreme cases, if the Timing Belt breaks while driving, it is possible to damage the Engine Valves. The cost to repair the Timing Belt is estimated at $106.90 for parts and $195.00 for labor. The cost to replace the CKP sensor is estimated at $108.35 and $136.50 for labor, or can be replaced at the same time as the timing belt for no additional labor. The cost to repair the Engine Valves is estimated at $325.00 for parts and $715.00 for labor. All prices are estimates based on $65.00 per flat rate hour and do not include diagnostic time or any applicable sales tax.
