This is my second 4Runner. After driving an SR5 for 3 years I decided to lease the Limited. After 3 years of reliability I decide to purchase it. 185,000+ miles later I am still enjoying the reliability of the best vehicle I've ever owned. It has never had any major mechanical problems. I've had to replace the battery twice, brake pads once (always parked outdoors), and only now do I have to replace the muffler. The only electrical problem is the CD player skipping. It has been so reliable I am going to drive it until the wheels fall off.
