Very reliable. Minor problems in pre-2005 models all fixed under warranty. The a/c blower may quit working or change to another speed without input from passengers, requiring a new wiring harness from the blower motor speed controller. The radiator fan motor may stop working in 2003 models, requiring a new wire between the powertrain control module (PCM) and fan motor. Some pre-2005 engines may develop a ticking sound from the engine at idle requiring replacement of the cylinder head and camshaft assembly. The rear wheels in pre-2006 models may chatter during low speed turns requiring installation of a revised clutch pack in the 8.8-inch, limited slip differential.
