2003 Buick Rendezvous CX AWD 4dr SUV (3.4L 6cyl 4A)
I just dumped mine. In 4 years: wheel bearing twice (the electronic controls for AWD are in the bearing assembly - a lousy design), heated seat burnt out, spare tire safety mechanism rusted shut (could not get spare out one night), and the best of all - valve lifter bolt sheared out of aluminum head. In the same time frame all I did was change the oil in a Honda Accord. A guy in my office also has 2003 and has had even worse problems including head gasket.
