I am surprised to hear so many comments about the reliability issues of the GX470. We bought my wife's 2006 GX470 about 2 years ago, with 82k miles. It just hit 100k miles, and we have had no issues with it, and have only had to keep up with the standard maintenance. I am just about to replace the original set of front brakes and rotors.
I've had a fair number of issues with my '03 4Runner, which I bought new. It has 160k miles on it. Many of the issues have been rust related:
- the frame had to be replaced last year.
- transmission cooler lines rusted out.
- steering intermediate shaft had to be replaced, due to rusted u-joint.
- steering hoses had to be replaced due to rust.
- left side running board brackets rusted out.
- both front turn signal sockets had to be replaced due to corrosion.
- spare tire winch rusted to the point that it was almost impossible to operate.
- rear suspension end links.
Other issues included:
- replaced both front wheel bearings.
- replaced front sway bar bushings twice.
- replaced front and rear calipers numerous times due to calipers becoming frozen. The left rear caliper is on its way out right now.
- torn CV boots at least twice.
- replaced the driver's side seatbelt socket.
- replaced the driver's side, rear seat seatbelt socket.
In the summer, the blend doors will often make noise.
While I like my 4Runner, it hasn't been trouble free. I've dumped $5,500 into it in the past year. I was hoping I was over the hump and it would be trouble-free for a while, but I suspect that I need about $500-$700 in rear brake work.
At some point, I'm going to have to cut my losses.
